Next, with reference to FIG. 7, the effect | action at the time of operating the vehicle information display apparatus 1 of embodiment of this invention with the touchscreen of the main monitor 2 is demonstrated.
First, with reference to FIG. 7, the outline of an effect | action of the vehicle information display apparatus 1 of embodiment of this invention is demonstrated. First, “search menu” → “name search” is selected from the uppermost operation screen of the car navigation device 18 shown in FIG. 7A to display the operation screen of FIG. Enter the name of. In the middle of this input, when the driver feels that the passenger compartment is hot and operates the third system selector switch 12 from the left, the uppermost operation screen of the air conditioner 22 shown in FIG. 7C is displayed. . The driver who has lowered the temperature setting of the air conditioner 22 on the operation screen of FIG. 7C operates the system selector switch 12 assigned to the car navigation device 18 in order to select the car navigation device 18 again. When the system changeover switch 12 is operated, the operation screen selection means 30 of the integrated processing device 10 selects an operation screen that the driver will want to operate from among the operation screens of the in-vehicle devices corresponding thereto, Is displayed on the main monitor 2.

  In this example, when the system changeover switch 12 is operated, the operation screen selection means 30 selects and displays the screen keyboard operation screen (FIG. 7 (d)) that was being input, so that the driver continues. You can enter the name of the destination. If the operation screen selected by the operation screen selection means 30 is different from the operation screen intended by the driver, the operation of the car navigation device 18 is performed by the top menu switch 14 that is always displayed at the lower part of the operation screen. You can move to the top layer of the screen with a single touch and then move to the operation screen of the desired level. As described above, the operation screen selection means 30 for selecting an operation screen of an appropriate hierarchy from the operation screens of the in-vehicle devices corresponding to the operated system changeover switch 12, and the selection by the operation screen selection means 30 is appropriate. The driver can quickly display the desired operation screen by the combination of the top menu switch 14 that can move to the uppermost layer of the operation screen of the vehicle-mounted device with one touch if not. On the other hand, when the return switch 16 is operated on the operation screen of FIG. 7D, the operation screen of FIG. 7C displayed immediately before that is displayed.

  Next, as shown in FIG. 7 (e), the driver who has searched the destination by the car navigation device 18 operates the system changeover switch 12 as shown in FIG. When the car navigation device 18 is selected again by the system changeover switch 12, the uppermost operation screen of the car navigation device 18 is displayed.

  Next, with reference to FIG. 8 thru | or 13, the control of the cursor by the cursor switches 9a-9d with which the vehicle information display apparatus 1 by embodiment of this invention is equipped is demonstrated. FIG. 8 is an enlarged front view of the sub-monitor 8 provided in the vehicle information display device 1 according to the present embodiment. The sub monitor 8 is disposed above the main monitor 2 and at a position farther from the driver than the main monitor 2 (in front of the vehicle). As shown in FIG. 8, the sub-monitor 8 is configured to display various information on the upper and lower two stages. In the upper part of the sub monitor 8, information such as the time and the current position of the vehicle is displayed in a horizontal row (this is OK). In the lower row, icons representing operation menus such as air conditioning and audio are displayed in a line.

  FIG. 9 shows an enlarged view of the cursor switches 9 a to 9 d provided on the handle 6. The cursor switches 9a to 9d are arranged near the outer periphery of the handle 6 and are positioned so that they can be easily operated with the thumb of the left hand of the driver who holds the handle. The cursor switch is composed of two buttons 9a and 9b for instructing the left and right direction, and two buttons 9c and 9d for changing the parameters of the operation menu selected by these buttons. Each button has a generally sector shape with a central angle of 90 °. An order cursor switch 9e is arranged in the center of the cursor switches 9a to 9d.

  Electrical contacts (not shown) are respectively arranged on the back side of the four buttons 9a to 9d of the cursor switch, and by pressing each button 9a to 9d, the electrical contacts arranged on the back side become conductive. When each electrical contact is conducted, the integrated processing apparatus 10 recognizes that the button has been pressed. Similarly, electrical contacts are also arranged on the back side of the order cursor switch 9e. When the cursor switch button 9a or 9b is pressed, the cursor position control means 34 incorporated in the integrated processing apparatus 10 moves the cursor displayed on the sub monitor 8 in the direction indicated by the pressed button. In FIG. 8, the cursor is positioned at “VOLUME” for increasing / decreasing the volume of the audio device 20, and the cursor is sequentially moved to “SOURCE”, “DISK”, “TRACK” by pressing the button 9b from this state. Moving. Further, when the button 9a is pressed while the cursor is at "VOLUME", the cursor sequentially moves to "TEMP", "MODE", and "FAN".

  When the user changes the setting parameter of the operation menu, the value can be changed by pressing the button 9c or 9d of the cursor switch. For example, the volume of the audio device 20 can be increased by pressing the button 9c in the state shown in FIG. 8, and the volume can be decreased by pressing the button 9d. In order to decrease the air volume of the air conditioner 22, the button 9a is pressed three times from the state shown in FIG. 8 to move the cursor to “FAN”, and then the button 9d is pressed.

  In the present invention, in the type of display device in which the operation menus are arranged in a row and the menu is selected by the cursor, the one located at the end of the operation menu row is relatively easy to operate and is located near the center. We found that the ones located were difficult to operate. This is because to move the cursor to the operation menu located at the end, the cursor always stops at that menu by pressing the cursor switch in the direction where the target operation menu is located many times regardless of the position of the cursor. It is. For example, when the operation menu is arranged as shown in FIG. 8, regardless of the initial position of the cursor, the button 9b is continuously pressed six times or more, or the button 9b is pressed for a predetermined time or more. By continuing, the cursor can be set to “TRACK” without looking at the sub monitor 8. Similarly, regardless of the initial position of the cursor, the cursor can be set to “FAN” by continuously pressing the button 9a six times or more, or by continuously pressing the button 9b for a predetermined time. On the other hand, when placing the cursor on the operation menu arranged near the center, the user first checks the current position of the cursor by looking at the sub-monitor 8 and needs the direction of the target operation menu. Since it is necessary to press the button 9a or 9b for the number of times, the operation is complicated.

  Therefore, in the vehicle information display device 1 according to the embodiment of the present invention, the standby position of the cursor is set near the center of the operation menu arranged in a line on the sub monitor 8, and the cursor switch is not operated for a predetermined time. In this case, the cursor is automatically returned to the standby position by the cursor position control means 34. In the present embodiment, the cursor standby position is set to the fourth from the left, which is the center of the seven operation menus arranged in a line. Preferably, the standby position is set at approximately the center of the operation menu. That is, the standby position is, for example, 2 to 4 if the operation menu is 5, 3 or 4 if it is 6, 3 to 5 if it is 7, and 4 or 5 if it is 8. There should be.

  Next, the control of the cursor position by the cursor position control means 34 will be specifically described with reference to FIGS. FIG. 10 is a flowchart of basic control of the cursor position by the cursor position control means 34, and FIG. 11 is a control for aligning the cursor with the function of the in-vehicle device expected to be used based on the running state of the vehicle. It is a flowchart of.

  First, in step S1 of FIG. 10, it is determined whether or not the cursor is at the volume setting of the audio device 20 which is the standby position. When the cursor is at the standby position, it is not necessary to move the cursor position by the cursor position control means 34, and thus one process of this control flow is terminated. Next, when the cursor is not at the standby position, the process proceeds to step S2 to determine whether or not the vehicle is traveling. In this embodiment, the time until the cursor position is returned to the standby position is changed during traveling and when the vehicle is stopped. In principle, it is preferable to operate the cursor switch without looking at the sub-monitor 8 during driving, so it is better to quickly return the cursor to the standby position. This is because the operability deteriorates if the cursor position is automatically moved frequently.

  If the vehicle is not running, the process proceeds to step S3, and it is determined whether or not a predetermined time has elapsed since the previous cursor switch was operated. In the present embodiment, the cursor is returned to the standby position when there is no operation of the cursor switch for 5 minutes while the vehicle is stopped. If five minutes have not elapsed since the cursor switch operation, the one-time processing of this control flow is terminated. If more than 5 minutes have elapsed since the cursor switch operation, the process proceeds to step S5, where the cursor is returned to the standby position.

  On the other hand, if the vehicle is traveling, the process proceeds to step S4, where it is determined whether or not a predetermined time has elapsed since the previous cursor switch operation. In the present embodiment, the cursor is returned to the standby position when there is no operation of the cursor switch for 1 minute during traveling. If one minute has not elapsed since the operation of the cursor switch, one process of this control flow is terminated. If one minute or more has elapsed after the operation of the cursor switch, the process proceeds to step S5, where the cursor is returned to the standby position.

  After the cursor is returned to the standby position in step S5, the process proceeds to step S6. In step S6, the cursor change notification means 36 notifies the user that the cursor position has been automatically changed by the cursor position control means 34. To do. FIG. 12 shows a display screen of the sub-monitor 8 in which the cursor change notification means 36 notifies the user when the cursor position is automatically changed. Instead of such a display screen or together with the display screen, the user can be informed that the cursor position has been automatically changed with a warning sound or the like.

  Next, a control flow in which the cursor position control unit 34 changes the cursor position according to the traveling state of the vehicle will be described with reference to FIG. First, in step S11, it is determined whether or not the vehicle has entered the tunnel. In the present embodiment, the cursor position control means 34 determines whether the vehicle has entered the tunnel based on the vehicle position data obtained by the car navigation device 18 and the map information stored in the car navigation device 18 in advance. Judging whether or not. If it is determined in step S11 that the vehicle has entered the tunnel, the process proceeds to step S15, and the cursor position control means 34 sets the cursor to the mode setting “MODE” which is one of the operation menus of the air conditioner 22. Move. This is because, when entering the tunnel, a lot of exhaust gas is contained in the air outside the vehicle, so that the user is highly likely to switch the mode setting of the air conditioner 22 to the vehicle interior circulation mode. In step S15, when the cursor position is moved to "MODE", the cursor change notification means 36 notifies the user to that effect, and ends the one-time process of this control flow.

  If it is determined in step S11 that the vehicle is not in the tunnel, the process proceeds to step S12, and it is determined whether or not the temperature in the passenger compartment is within a predetermined range. If the temperature in the passenger compartment is outside the predetermined range, the process proceeds to step S16. If the temperature is outside the predetermined range, the passenger feels hot or cold, and there is a high possibility that the temperature setting of the air conditioner 22 will be changed. In step S16, the cursor position control means 34 air-conditions the cursor. It is moved to the temperature setting “TEMP” which is one of the operation menus of the apparatus 22. In step S16, when the cursor position is moved to “TEMP”, the cursor change notifying means 36 notifies the user to that effect, and ends the one-time processing of this control flow.

  If it is determined in step S12 that the temperature in the passenger compartment is within the predetermined range, the process proceeds to step S13, and it is determined whether or not the sound quality of the radio of the audio device 20 has deteriorated. If the sound quality of the radio has deteriorated, the process proceeds to step S17. When the sound quality of the radio is deteriorated, it is highly likely that the passenger changes the sound source of the audio device 20 to something other than the radio. Therefore, in step S17, the cursor position control means 34 operates the audio device 20 with the cursor. Move to sound source switching “SOURCE” which is one of the menus. In the present embodiment, the cursor position control means 34 determines whether or not the sound quality of the radio has deteriorated based on the detuning signal output from the radio detection circuit. In step S17, when the cursor position is moved to "SOURCE", the cursor change notifying means 36 notifies the user to that effect, and ends the one-time process of this control flow.

  If it is determined in step S13 that the sound quality of the radio has not deteriorated, or if the radio is not being used, the process proceeds to step S14, and it is determined whether or not an intersection with poor visibility is approached. If the vehicle approaches an intersection with poor visibility, the process proceeds to step S18. When approaching an intersection with poor visibility, there is a high possibility that the driver will decrease the volume of the audio device 20 in order to listen to the sound outside the vehicle, so in step S18, the cursor position control means 34 moves the cursor to the audio device 20 Is moved to the volume adjustment “VOLUME” which is one of the operation menus. In the present embodiment, the cursor position control means 34 is based on the vehicle position data obtained by the car navigation device 18 and the map information stored in the car navigation device 18 in advance, and the vehicle approaches an intersection with poor visibility. It is determined whether or not. In step S18, when the cursor position is moved to “VOLUME”, the cursor change notification means 36 notifies the user to that effect, and ends the one-time processing of this control flow.

  Next, with reference to FIG. 13, the operation of the sequence cursor switch 9e of the vehicle information display device 1 according to the embodiment of the present invention will be described. The cursor displayed on the sub monitor 8 can also be moved by pressing the order cursor switch 9e. When the order cursor switch 9e is repeatedly pressed, the cursor position control means 34 moves the cursor in the order of numbers shown in the lower part of FIG. In the example of FIG. 8, when the order cursor switch 9e is pressed once, the cursor advances from the reference position “VOLUME” to “FAN”. Further, each time the order cursor switch 9e is pressed once, the cursor is moved in the order of "MODE", "SOURCE", "TRACK", "TEMP", "DISK".
