It is configured as follows.
JP 2004-351949 A

  By the way, when lighting control of indoor lighting is performed in response to the passenger getting on and off as described above, lighting control suitable for the operation of the passenger must be performed on the driver seat side or the passenger seat side where the passenger gets on and off. In addition to not being able to obtain a sufficient interior decoration effect, useless lighting is performed and power is wasted.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an interior illumination lamp control device that performs lighting control of a plurality of interior illumination lamps provided in a vehicle interior. It is to improve the texture of the passenger compartment efficiently by devising the lighting control.

  In order to achieve the above object, in the vehicle interior illumination light control device according to the first aspect of the present invention, the interior illumination light around the driver seat or around the passenger seat respectively in accordance with the opening operation of the door on the driver seat side or the passenger seat side. The lighting control was performed.

  That is, the invention of claim 1 is directed to a vehicle interior illumination light control device that performs lighting control of a plurality of interior illumination lights provided in a vehicle interior. And a driver seat door open detecting means for detecting that the driver seat side door is open, a passenger seat door open detecting means for detecting that the passenger seat door is open, and the driver seat door open detecting means. When the opening on the driver's seat side is detected, a first lighting control means for lighting a plurality of indoor lighting lights around the driver's seat in a predetermined sequence, and the passenger's seat door opening detection means It is assumed that there is provided second lighting control means for lighting a plurality of room illumination lamps in the vicinity of the passenger seat in a predetermined order when door opening is detected.

  With this configuration, a passenger's ride on the driver's seat or passenger's side is detected by opening the driver's or passenger's side door, and the interior lighting around the driver's seat or the passenger's seat is detected according to the ride operation. Since the lights can be sequentially turned on, only the side on which the occupant gets on can be rendered by the interior lighting, and the texture of the interior of the vehicle can be improved efficiently.

  In the vehicle interior illumination light control device according to the second aspect of the present invention, the interior illumination lights around the driver's seat and the passenger's seat are respectively controlled according to the unlocking operation of the driver side or passenger side door by the keyless entry system. Lighting control was performed.

  That is, in the invention of claim 2, in the vehicle having the driver side door and the passenger side door that can be unlocked by the keyless entry system, the interior lighting for controlling the lighting of a plurality of interior illumination lamps provided in the passenger compartment is provided. Intended for lamp control devices. And a driver seat side unlock detecting means for detecting unlocking of the driver seat side door, a passenger seat side unlock detecting means for detecting unlocking of the passenger seat side door, and the driver seat side unlock detecting means. When the unlocking of the driver's seat side door is detected by the above, a first lighting control means for lighting a plurality of interior illumination lamps around the driver's seat in a predetermined order, and an assistant by the passenger seat side unlock detecting means When the unlocking of the seat side door is detected, a second lighting control means for lighting a plurality of room illumination lights around the passenger seat in a predetermined sequence is provided.

  With this configuration, even in the configuration in which the doors on the driver's seat and passenger's side are unlocked using the keyless entry system, the unlocked side in the vicinity of the driver's seat or the passenger's seat according to the unlocking operation Since the interior illumination lights can be sequentially turned on, it is possible to appropriately and surely produce the ride with the interior illumination lights, and to efficiently improve the texture of the interior of the interior.

  In the above-described configuration, the lighting control unit is configured to sequentially turn on the plurality of indoor illumination lamps from the outside of the vehicle toward the inside of the vehicle interior (the invention of claim 3). By doing so, the interior lighting lights up so as to invite the occupant to the passenger compartment in accordance with the occupant's riding operation, so that the texture given to the occupant when getting on can be further improved.

  Further, as described above, instead of lighting the room lighting from the outside of the vehicle toward the interior of the vehicle, a plurality of room lighting may be sequentially turned on from the vehicle rear side toward the vehicle front side ( Invention of Claim 4). In this way, since the interior lighting lights are turned on in accordance with the driver's driving consciousness ahead, it is possible to produce an effect that matches the driving image of the occupant and to improve the texture of the passenger compartment.

  In the above configuration, it is preferable that the lighting control means is configured to sequentially turn on the room illumination lamps for a predetermined period (invention of claim 5). Here, the predetermined period may be a preset time such as a time required for the occupant to get on, or a predetermined operation (such as ignition ON) meaning completion of the occupant's boarding. It may be the time until it is performed.

  Thus, by sequentially lighting the interior illumination lamps for a predetermined period, it is possible to continuously perform the interior illumination according to the occupant's operation, and thus it is possible to continue improving the texture of the vehicle interior.

  Further, the lighting control means may be configured to sequentially turn on the indoor lighting until the occupant's boarding operation is completed (invention of claim 6). Here, the completion of the ride operation of the occupant means a case where the occupant closes the door or turns an ignition key. As a result, the interior lighting is sequentially turned on until the occupant completes the riding operation, so that the texture of the passenger compartment can be reliably improved during the occupant's riding operation.

  Furthermore, it is preferable that the lighting control means is configured to end the sequential lighting of the room illumination lamps at an earlier timing of the elapse of a predetermined period or the completion of the boarding operation by the occupant (invention of claim 7). In this way, when the ride operation by the occupant is performed and it is desired to improve the interior of the vehicle interior, the interior illumination lights are sequentially turned on, and when unnecessary, the interior illumination lights are turned off, which is useless. There is no need to perform lighting control of the interior lighting, and the texture of the vehicle interior can be improved effectively.

  As described above, according to the vehicle interior illumination light control device of the present invention, the driver's seat can be opened by opening the door on the driver's seat or passenger's side, or by unlocking the driver's seat or passenger's side of the keyless entry system. Since the interior lighting around the passenger seat or the passenger seat is sequentially turned on, the interior texture of the passenger compartment can be improved efficiently in accordance with the passenger's riding operation.

  In addition, if the interior lighting is turned on sequentially from the outside of the vehicle toward the inside of the vehicle, a more suitable effect can be achieved by the occupant's riding operation, and if the indoor lighting is turned on sequentially from the rear of the vehicle to the front of the vehicle Thus, it is possible to provide a more suitable effect for the driver's driving awareness, and to improve the texture of the passenger compartment.

  Furthermore, by continuously lighting the room illumination lamp within a predetermined period or until the boarding operation is completed, it is possible to continuously improve the texture of the vehicle interior for a necessary period. In addition, the lighting of the interior lighting is stopped at the earlier of the predetermined period of time or when the riding operation is completed, thereby improving the quality of the interior of the vehicle efficiently without causing unnecessary lighting of the interior lighting. can do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature and is not intended to limit the present invention, its application, or its use.

Then, courtesy lamps 50 and 50 are provided at the vehicle interior side of the driver seat side door 5 and the passenger seat side door 6 and in the lower part of the vehicle rear side, respectively.

  Here, the driver seat side and passenger seat side doors 5 and 6 are respectively provided with door opening detection sensors 5b and 6b (driver seat door opening detecting means, passenger seat doors) for detecting, for example, unlocking or opening of the door. Open detection means), and output signals from the door open detection sensors 5b, 6b are input to the controller 60.

  The various switches 42, 43, 46, 48, 49 and the instrument panel 45 described above are provided with illumination means such as a light bulb for lighting them so that their positions and indications can be read accurately even at night. For example, it is configured to light up in response to lighting of a headlight (not shown). In addition, indoor lighting such as the centralized display 44, the instrument panel lighting device 47, and the courtesy lamp 50, including the various switches 42, 43, 46, 48, 49 and the instrument panel 45, is provided on the driver's seat side or When the passenger seat side doors 4 and 5 are opened, the doors are sequentially turned on.

  That is, as shown in FIG. 1, the various switches 42, 43, 46, 48, 49, the instrument panel 45, the centralized display 44, the instrument panel lighting device 47, and the courtesy lamp 50 are respectively connected to a controller 60 as a lighting control means. It is connected and is turned on or off by an output signal from the controller 60. The output signal from the controller 60 is output in conjunction with the ON / OFF of the headlamps, and is output according to the input signals from the door open detection sensors 5b and 6b accompanying the opening and closing operations of the doors 4 and 5. Is done. In the following, the lighting control of the interior lighting according to the opening and closing of the doors 4 and 5 will be described in detail.

-Lighting control-
In this embodiment, as shown in FIG. 2, when the door 5 on the driver's seat side is opened, lighting control is performed so that the interior lighting around the driver's seat is sequentially lit from the outside of the vehicle toward the interior of the vehicle. . The lighting control at this time will be described in detail below based on the flow of FIG. In this embodiment, the central display 44, the audio operation button 43 lamp, and the air conditioner setting dial 42 lamp can be turned on or off independently on the left and right sides (driver's seat side and passenger seat side). Therefore, when the door 5 on the driver's seat side is opened, only the driver's seat side portion is turned on or off.

  In the flow of FIG. 3, it is first determined in step SA1 whether the door 5 on the driver's seat side is open. If it is determined that the door 5 is open (in the case of YES), the following step SA2 is performed. Then, the courtesy lamp 50 provided on the door 5 on the driver's seat side is turned on. On the other hand, when it is determined in step SA1 that the driver's seat door 5 is not open (in the case of NO), the lighting control accompanying the opening / closing of the door is unnecessary, and thus this flow is finished as it is (end).

  After the courtesy lamp 50 is turned on in step SA2, it is determined whether or not a predetermined time has elapsed from that state (step SA3). If the predetermined time has not elapsed (in the case of NO), the predetermined time has elapsed. On the other hand, if it is determined that the predetermined time has elapsed (in the case of YES), the lamp of the power window switch 48 is turned on in the subsequent step SA4. The lamp of the power window switch 48 also stands by until a predetermined time elapses (in the case of NO in step SA5), while if the predetermined time has elapsed (in the case of YES in step SA5), the process proceeds to step SA6 and proceeds to the instrument panel. The lamp of the operation switch group 46 is turned on.

  In the same manner, the meter illumination of the instrument panel 45, the centralized display 44, the lamp of the audio operation button 43 (audio illumination) and the lamp of the air conditioner setting dial 42 (air conditioner illumination) are sequentially turned on at predetermined time intervals. (Steps SA7 to SA14). FIG. 4 schematically shows the sequential lighting. Accordingly, in response to the opening operation of the driver's seat side door 5, the driver's seat side interior lighting is sequentially lit from the outside of the vehicle toward the inside of the vehicle, and the interior lighting according to the passenger's riding operation The lighting can improve the texture of the passenger compartment.

  In this embodiment, as shown in FIG. 3 and FIG. 4, the interior lighting is not turned off until all the interior lighting on the driver's seat is turned on. As indicated by the alternate long and short dash line in FIG. 4, each indoor illumination lamp may be turned on and then turned off after a predetermined time has elapsed.

  Then, after all the interior illumination lights on the driver's seat side are turned on as described above, a predetermined time is left (step SA15), and all the illumination lights are turned off (step SA16). Thereafter, it is determined whether or not the driver's seat door 5 is closed (step SA17). If the driver's seat door 5 is closed (in the case of YES), the lighting control becomes unnecessary, and this flow ends (END). On the other hand, if the driver's seat door 5 is open (in the case of NO), it is determined in the subsequent step SA18 whether or not the lighting or extinguishing of the interior illumination lamp as described above has been performed a predetermined number of times. If it is determined in step SA18 that the above-described lighting control has been performed a predetermined number of times (in the case of YES), this flow is terminated as it is, but if it is determined that the predetermined number of times has not yet been performed (in the case of NO). ), The process returns to the step SA2, and the various indoor illumination lights are sequentially turned on again. Here, the predetermined number of times means the number of times of lighting control performed until the occupant's boarding operation is reliably completed.

  In this way, if the number of times the indoor lighting is sequentially turned on is terminated at a predetermined number of times, even if the driver's seat side door 5 remains open, the door 5 opens and passengers get on. Since the lighting control can be performed only at a time when there is a high possibility of performing, the interior of the vehicle interior can be effectively performed without using wasted power.

  On the other hand, also when the door 6 on the passenger seat side opens and closes, as shown in FIG. 2, the interior lighting around the passenger seat is sequentially turned on from the outside of the vehicle toward the interior of the vehicle. Here, the lighting control when the driver's seat side door 5 is opened and closed, as shown in FIG. 5, after the courtesy lamp 50 of the passenger seat door 6 is turned on (step SB2), the power on the passenger seat side is turned on. Turning on the lamp of the window switch 49 (step SB4), turning on the lamp of the instrument panel operation switch 46 and the meter illumination of the instrument panel 45 when the driver seat side door 5 is opened (steps SA6 and SA8 in FIG. 3). Instead, since the instrument panel illumination device 47 (instrument lamp lamp) is turned on (step SB6), the detailed description is omitted. When the passenger side door 6 is thus opened, the central display 44, the audio operation button 43 and the air conditioner setting dial 42 located near the center in the vehicle width direction are lit only on the passenger side. .

  Here, the controller 60 that executes the control flow of FIG. 3 when the driver's seat side door 5 is opened is the first lighting control means, and the control flow of FIG. 5 is when the passenger seat side door 6 is opened. The controller 60 to be executed corresponds to the second lighting control means.

  With the above configuration, when the driver's side door 5 or the passenger's side door 6 is opened, the interior lighting around the driver's seat or the passenger's seat is lit in sequence, so that the passenger's riding operation can be handled. Can improve the quality of the interior of the vehicle. In addition, since the interior lighting is sequentially turned on from the outside of the vehicle toward the interior of the vehicle so as to image the occupant's riding operation, the texture of the interior of the vehicle can be further improved.

  In the present embodiment, only the interior lighting around the driver seat or the passenger seat is turned on in response to the opening and closing of the driver seat side door 5 or the passenger seat side door 6, but this is not restrictive. For example, when only the driver's seat side door 5 is open, the interior lighting is sequentially turned on from the driver's seat door side (the vehicle exterior side) toward the vehicle interior, and then the passenger seat door side ( You may make it turn on an interior illumination light sequentially toward the vehicle exterior. In this way, the interior lighting corresponding to the passenger's boarding operation can be expressed in the entire vehicle interior, so that the texture of the vehicle interior can be further improved.

(Embodiment 2)
FIG. 6 shows the lighting state of the indoor lighting lamp according to the second embodiment of the present invention, and FIGS. 7 and 8 show the flow of lighting control according to the second embodiment, respectively. Since the entire indoor configuration is the same and the lighting order of the indoor illumination lamps is different, the same portions are denoted by the same reference numerals and only the different portions will be described below. That is, in the second embodiment, the interior lighting is not sequentially turned from the outside of the vehicle toward the vehicle interior as in the first embodiment, but from the rear side of the vehicle toward the front so as to match the driving awareness of the driver. Turn on the room lights sequentially.

  Specifically, as shown in FIG. 7, when it is determined in step SC1 that the driver's seat side door 5 is opened (in the case of YES), the courtesy lamp 50 and the air conditioner setting dial 42 are turned on in step SC2. After the predetermined time has elapsed (in the case of YES at step SC3), the lamp of the power window switch 48 and the lamp of the audio operation button 43 are turned on at step SC4. In step SC1, the open state of the door 5 is determined. However, the present invention is not limited to this, and it may be determined whether the ignition switch is turned on.

  Then, after a further predetermined time has elapsed in this state (in the case of YES at step SC5), the lamp and centralized display 44 of the instrument panel operation switch group 46 are turned on at step SC6, and after the predetermined time has elapsed (YES at step SC7). ), The meter illumination of the instrument panel 45 is turned ON (step SC8). In this way, by sequentially lighting the interior lighting around the driver's seat in the passenger compartment from the rear side of the vehicle toward the front, it is possible to realize interior lighting according to the driver's driving consciousness, and to improve the texture of the passenger compartment It can be improved further.

  Here, the lamp of the setting dial 42 of the air conditioner, the lamp of the audio operation button 43 and the centralized display 44 arranged near the center in the vehicle width direction in the passenger compartment are the driver's seat side and the assistant as in the first embodiment. The seat side can be lit separately.

  As described above, after the room illumination lamps around the driver's seat are sequentially turned on, after a predetermined time has elapsed (in the case of YES at step SC9), all the illumination lamps are temporarily turned off (step SC10). Then, in the following step SC11, it is determined whether or not the driver seat side door 5 is closed. If the door 5 is closed (in the case of YES), this flow is finished as it is (end), while the door 5 is still If it is open (in the case of NO), the process proceeds to step SC12 to determine whether or not the lighting control as described above has been performed a predetermined number of times.

  If it is determined in step SC12 that the lighting control has been performed a predetermined number of times (in the case of YES), this flow is finished as it is (end), while it is determined that the lighting control has not been performed a predetermined number of times. In the case of NO (in the case of NO), the process returns to the step SC2 to sequentially turn on the indoor lighting lamps.

  On the other hand, with respect to lighting control when the passenger seat side door 6 is opened, the instrument panel operation when the driver seat side door 5 is opened as shown in FIG. The instrument panel illumination device 47 (instrument illumination lamp) is turned on (step SD6) instead of turning on the lamp illumination of the switch 46, the centralized display 44, and the meter illumination of the instrument panel 45 (steps SC6 and SC8 in FIG. 7). Therefore, detailed explanation is omitted.

  Here, as in the first embodiment described above, when the driver seat side door 5 is opened, the controller 60 that executes the control flow of FIG. 7 is the first lighting control means, and the passenger seat side door 6 is opened. Further, the controller 60 that executes the control flow of FIG. 8 corresponds to the second lighting control means.

  With the above configuration, according to this embodiment, when the driver's seat side door 5 or the passenger's seat side door 6 is opened, the interior illumination lights around the driver's seat or the passenger's seat turn on sequentially from the vehicle rear side toward the vehicle front side. Therefore, the interior decoration effect according to the driver's driving consciousness can be obtained, and the texture of the passenger compartment can be improved. In addition, the lighting control of the interior lighting is performed in response to the opening operation of the door on the driver's side or the passenger's side, so that the interior lighting is not turned on unnecessarily on the side where no occupant is riding. The texture of the passenger compartment can be improved well.

  In this embodiment as well, only the interior lighting around the driver seat or the passenger seat is turned on in response to the opening and closing of the driver seat side door 5 or the passenger seat side door 6, but this is not restrictive. For example, when only the driver's seat side door 5 is open, the interior illumination lights around the driver's seat are sequentially turned on from the rear side of the vehicle to the front, and then the interior illumination lights around the passenger seat are moved forward from the rear side of the vehicle. You may make it light up sequentially. In this way, the interior lighting suitable for the driving consciousness of the occupant can be expressed in the entire vehicle interior, so that the texture of the vehicle interior can be further improved.

(Embodiment 3)
FIG. 9 shows the lighting state of the interior lighting according to the third embodiment of the present invention, and FIG. 10 shows the flow of lighting control at that time, respectively. 4 Since the front instrument panel illumination device 47 is configured so that it can be lit separately on the left and right, and the timing of lighting the interior illumination lamps is different, the same parts will be denoted by the same reference numerals and only the different parts will be denoted below. Will be explained. That is, in the third embodiment, when the driver seat side door 5 and the passenger seat side door 6 are opened as in the first and second embodiments described above, the interior lighting lights around the driver seat and the passenger seat are made independent. Instead of lighting at separate timings, the lighting timings of both are made to coincide.

  When the flow shown in FIG. 10 starts (start), it is first determined in step SE1 whether the driver's seat side door 5 is open. If it is determined that the driver's seat door 5 is open (in the case of YES), the process proceeds to step SE2 to determine whether or not the passenger's seat side door 6 is open, and the passenger's seat side door 6 is not open. In the case of NO, only the interior lighting around the driver's seat is turned on sequentially (step SE22), while when the passenger seat side door 6 is open (in the case of YES), both doors are open. Therefore, the interior illumination lights around the driver seat and the passenger seat are turned on (step SE3 and subsequent steps).

  On the other hand, even if it is determined in step SE1 that the driver's seat side door 5 is closed (in the case of NO), it is determined in step SE23 whether or not the passenger seat door 6 is open. If it is determined in step SE23 that the passenger seat door 6 is open (in the case of YES), only the passenger seat door 6 is open. Only turn on sequentially. On the other hand, if it is determined in step SE22 that the passenger seat door 6 is closed (in the case of NO), the driver seat side door 5 and the passenger seat side door 6 are closed, so that lighting control is performed. End this flow (end).

  Note that the lighting control performed in steps SE22 and SE24 described above is substantially the same as the lighting control of the various indoor lighting lamps shown in FIGS. 3 and 5 of the first embodiment, and the description of the specific control is omitted. However, as will be described later, in this embodiment, the centralized display 44 located near the center in the vehicle width direction in the vehicle interior, the lamp of the audio operation button 43 and the lamp of the air conditioner setting dial 42 are provided on the driver's seat side and the passenger seat. The driver's seat side portion and the passenger seat side portion are lit at the same time.

  Hereinafter, when it is determined in step SE2 that the front passenger side door 6 is open (in the case of YES), that is, when it is determined that both the driver side door 5 and the front passenger side door 6 are open. Next, the step SE3 transition will be described in detail. In step SE3, the courtesy lamps 50, 50 on the driver's seat side and the passenger seat side are turned on simultaneously. And it waits until it determines with predetermined time having passed by step SE4 (in the case of YES), and turns on the lamp | ramp of the power window switches 48 and 49 of the driver's seat side and the passenger seat side simultaneously at step SE5. Thereafter, at predetermined time intervals, the lamps of the instrument panel operation switch group 46 on the driver's seat side and the left side portion of the instrument panel illumination device 47 (instrument panel lamp) on the passenger seat side, the meter illumination of the instrument panel 45 on the driver's seat side, The right part of the instrument panel illumination device 47 (instrument panel lamp) on the passenger seat side is turned on simultaneously (steps SE6 to SE9).

  Thus, when both the driver seat side door 5 and the passenger seat side door 6 are open, the driver seat side and the passenger seat side sequentially light sequentially from the outside of the vehicle toward the vehicle interior, The texture of the passenger compartment can be further improved. In addition, by matching the lighting timing of these interior lighting lights, the lighting lights (for example, the centralized display 44) near the center in the vehicle width direction in the vehicle interior that are lighted thereafter can be separated on the driver's seat side and the passenger seat side. It does not give a sense of incongruity even if it is turned on. Therefore, it is not necessary to use a configuration in which the illuminating lamp disposed near the center in the vehicle width direction in the vehicle interior can be separately lit on the driver seat side and the passenger seat side as in the first and second embodiments. The configuration and control of the illumination lamp can be simplified.

  Specifically, as described above, after the meter illumination of the instrument panel 45 and the right part of the instrument panel illumination device 47 (instrument illumination lamp) are lit in step SE9, after a predetermined time has elapsed (step SE10), A centralized display 44 disposed near the center in the vehicle width direction, an audio operation button 43 lamp, an air conditioner setting dial 42 lamp, and a shift indicator 51 lamp provided along the lever guide groove 1b, respectively. Then, the lamps are sequentially turned on at predetermined intervals (steps SE11 to SE17).

  After all the illumination lamps in the vehicle interior are turned on in this way, all the illumination lamps are temporarily turned off (step SE19) after a predetermined time has elapsed (step SE18). Then, in step SE20, it is determined whether or not the driver side and passenger side doors 5, 6 are closed. If the doors are closed (in the case of YES), this flow is ended as it is (end). On the other hand, if it is determined that the door is still open (in the case of NO), it is determined in the subsequent step SE21 whether or not the above-described lighting control has been performed a predetermined number of times. In the case of YES), this flow is finished as it is (end). If it is determined in step SE21 that the above-described lighting control has not been performed a predetermined number of times (in the case of NO), the process returns to step SE1 and the driver side and passenger side doors 5, 6 are in the open state. Detection is performed again, and predetermined lighting control is performed again. Here, in step SE21, it is determined whether or not the number of lighting controls currently performed on the door open side has reached a predetermined number.

  Therefore, in the lighting control performed by the flow shown in FIG. 10, when only one of the driver side door 5 or the passenger side door 6 is open, the interior lighting around the driver seat or the front passenger seat respectively. When the driver seat side door 5 and the passenger seat side door 6 are open, the interior lighting lights around the driver seat and the passenger seat are at the same timing from the vehicle exterior toward the vehicle interior. It will light up sequentially. In other words, when one door is open and the lighting control of the interior lighting is being performed, when the other door is opened, it waits for all of the interior lighting on the one side to be turned on and turned off. Thus, both of the indoor lighting lights are sequentially turned on simultaneously. As a result, even if one of the doors is opened first and then the other door is opened, the interior lighting is unified in the vehicle interior, further improving the vehicle interior texture. can do.

You may make it turn on an indoor illumination light sequentially from the side toward the front.

  Further, in this embodiment, even if one door is opened and the other doors are opened while the lighting control of the interior lighting around the one side is being performed, all the lighting lights are turned on once. The lighting control of the other side lighting is not performed until the other side is turned off, but this is not the case, and when the other door opens, the lighting control on one side is stopped and the operation is stopped. The interior lighting around the seat and around the passenger seat may be turned on simultaneously. In this case, a step for determining whether the door is opened or closed may be provided after each step of turning on the respective indoor lighting on the driver's seat or passenger's seat.

  In addition, when the interior lighting lights around the driver seat and the passenger seat are turned on at the same time, when one of the driver seat side and the passenger seat side doors 5 and 6 is closed, only the other side is turned on. You may make it transfer to a proper control. In this case, a step for determining whether the door is opened or closed is provided after each step of lighting the indoor lighting lamps on the driver's seat side and the passenger seat side at the same time. It suffices to have a configuration in which only the lamps are again turned on sequentially from the beginning.

  Furthermore, in this embodiment, when both the driver seat side and the passenger seat side doors 5 and 6 are opened, the interior lighting lights around the driver seat and the passenger seat are controlled to be turned on simultaneously. Not only, but if the other door opens when the indoor lighting on one side is already lit in sequence, the indoor lighting (such as a centralized display) located near the center of the vehicle width is turned on In order to match the timing, after the one-side room illumination lamps are sequentially turned on, the room illumination lamps near the center may be turned on after waiting for the other-side room illumination lamps to be lit. In this case, a step of determining whether or not the other door is open before turning on the centralized display 44 may be provided.

(Other embodiments)
The configuration of the present invention is not limited to the above-described embodiments, but includes various other configurations. That is, in each of the above embodiments, the opening state of the driver side and passenger side doors 5 and 6 is detected and the lighting control of the interior lighting is performed. In such a vehicle, the unlocking of the driver side door 5 or the passenger side door 6 may be detected by the keyless entry system, and the lighting control of the interior lighting may be performed. In this case, for example, it is necessary to provide the driver side unlock detection means and the passenger side unlock detection means so that the door unlock can be detected based on the unlock signal transmitted from the transmitter of the keyless entry system. There is.

  Further, in each of the above embodiments, when deciding whether to repeat the lighting control, it is determined whether the door is in a closed state or whether the lighting control has been performed a predetermined number of times. It is not limited, and only one of them may be performed. In other words, the lighting control of the room lamp may be repeated until the door is closed or the lighting control is performed a predetermined number of times or more.

  Further, in each of the embodiments, it is determined whether or not the lighting control has been performed a predetermined number of times or more. However, the present invention is not limited to this. For example, it may be determined whether or not a predetermined time has elapsed. In addition, this predetermined time means the time estimated that a passenger | crew's boarding operation is completed.

  Furthermore, in each of the above embodiments, it is determined whether or not the door is closed after the lighting control is performed, but this is not a limitation, for example, whether or not the ignition key is inserted into the key cylinder, It may be determined whether the ignition switch is ACC or ON, or it may be determined whether the occupant gets on a weight sensor provided on the seat. In other words, any device can be used as long as it can detect the passenger's boarding.

  Further, in each of the above embodiments, the room illumination lamps are sequentially turned on and turned on. However, the present invention is not limited to this. For example, as shown in FIG. The illuminance may be shifted to 100% in order. Note that the example of FIG. 11 shows that the illuminance of the interior illumination light sequentially reaches 100% from the outside of the vehicle toward the interior of the vehicle when the driver's seat side door 5 is opened. It is configured to be turned on at low illuminance with opening. Furthermore, as indicated by the one-dot chain line in FIG.

  As described above, the vehicle interior illumination light control device according to the present invention sequentially turns on the interior illumination lights in accordance with the open / closed states of the driver side and passenger side doors, so that passengers can get on with their riding operation and driving awareness. Since a combined decoration effect can be obtained and the texture of the interior of the vehicle can be improved effectively, it is particularly useful for, for example, lighting control of interior lighting in conjunction with opening and closing of a door.
