Japanese Patent Laid-Open No. 11-348652 JP 59-167374 A

  In the conventional direction indicator, the flasher relay is used for both blinker lamp blinking and hazard lamp blinking. When the blinker relay is stopped by the blinker canceller, blinker lamp blinking stops and the hazard lamp blinking function Is also stopped. In order to solve this problem, it is conceivable to provide flasher relays for blinking the blinker lamp and blinking the hazard lamp. However, the flasher relay is expensive and is not preferable from the viewpoint of reducing the number of parts.

  In the winker canceller described in Patent Document 1, a hazard switch is provided in parallel with the winker canceller circuit, and a bypass switch for operating a flasher relay that closes in conjunction with the hazard switch is provided. However, by adding this bypass switch, it is necessary to take measures for preventing leakage due to water.

  Further, when the winker cancel output from the control unit is turned off due to a failure of the winker canceller circuit, there is a problem that not only the winker canceller mechanism but also the original direction indicating function is stopped.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a robust vehicular direction indicating device capable of simplifying the configuration by reducing the number of flasher relays and maintaining the original direction indicating function even when a blinker canceller circuit fails. is there.

  In order to achieve the above object, the present invention provides a vehicle direction indicator having a winker canceller control unit that outputs a winker cancel signal for stopping a direction indication operation for blinking a winker lamp, and a winker switch connected to the winker lamp. A flasher relay as a winker relay connected in series with the winker switch, a cancel relay connected between the flasher relay and the winker switch, and the winker lamp connected in parallel with the cancel relay. There is a first feature in that a hazard switch for instructing an emergency flashing operation is provided, and the cancel relay is turned off by the blinker cancel signal.

  Further, the present invention has a second feature in that a wincassette switch interlocked with the winker switch is provided and the cancel relay is turned on when the wincassette switch is turned on.

  According to the present invention having the first and second features, the blinking blinker lamp direction indicating operation is stopped by turning off the cancel relay. However, since the hazard switch is provided in parallel with the cancel relay, the blinker lamp is connected to the flasher relay by turning on the hazard switch. Therefore, the blinker lamp blinks as a hazard lamp while the hazard switch is turned on by an on / off operation of a predetermined cycle by the flasher relay.

  As described above, a single flasher relay can be shared for the blinking operation as the direction instruction and the blinking operation as the hazard display, and the operation of the blinker canceller does not affect the hazard display.

  A steering angle detection signal from the steering angle sensor 16 is input to the meter control unit 46b via the input terminal 62, and a win cassette signal from the win cassette switch (described later) is input to the meter control unit 46b via the set signal terminal 63. The The steering angle detection signal input from the input terminal 62 is A / D converted by the AD input circuit 71 and input to the CPU 51. The wincassette signal input from the set signal terminal 63 is input to the CPU 51 via the switch input circuit 72. Further, the winker cancel signal output from the CPU 51 is input to an external device (a cancel relay 65 described later) via a winker cancel signal terminal 64.

  As the relays, a cancel relay 65 and a position relay 66 are provided in addition to the winker relay 21. Further, a hazard switch 67, a winker switch 68, a position switch 69, and a wincassette switch 70 are provided as switches. The winker switch 68, the position switch 69, and the wincassette switch 70 operate in conjunction with each other. The relays are disposed, for example, above the engine in the center of the vehicle body, and the switches are provided on the handle 11 or the periphery thereof.

  The blinker relay 21 is a flasher relay that has a coil portion and a contact point connected to an oscillation circuit, and energizes the coil portion at a predetermined cycle to turn the contact point on and off. The blinker relay 21 is also used for the operation of the hazard lamp. A power source is connected to the contact of the cancel relay 65 via the contact of the blinker relay 21 and is connected to one of the hazard switches 67 which is a dual type. The power source connected to the winker relay 21 is connected to the winker switch 68 via the cancel relay 65.

  A separate power source is connected to the second switch 67 b of the hazard switch 67 that is a duplex type, and this power source is connected to the common terminal of the position switch 69 via the second switch 67 b of the hazard switch 67.

  One end of the coil of the cancel relay 65 is connected to the power source, and the other end is connected to the winker cancel signal terminal 64. Similarly, one end of the coil of the position relay 66 is connected to the power source, and the other end is connected to the blinker cancel signal terminal 64. One end of the coil of the wincassette switch 70 is connected to the power source, and the other end is connected to the set signal terminal 63.

  The first switch 67a of the hazard switch 67 has a common contact and two individual contacts, and one of the two individual contacts is connected to the two right blinker lamps FR and RR on the front and rear of the vehicle body, and the blinker Connected to the indicator input terminal 47. The other of the two individual contacts is connected to two left blinker lamps FL and RL on the front and rear sides of the vehicle body and to the blinker indicator input terminal 48.

  Furthermore, one of the two individual contacts of the position switch 68 is connected to the front right blinker lamp FR of the vehicle body and to the contact of the position relay 66. The other individual contact of the position switch 68 is connected to the front left blinker lamp FL of the vehicle body and to the contact of the position relay 66.

  In the configuration of the relay and the switch, first, in order for the driver to change the course of the vehicle to the left side, the blinker switch 68 is switched to the individual contact side connected to the front left blinker lamp FL and the rear left blinker lamp RL. When the operation is performed, the wincassette switch 70 is turned on and is input from the set signal terminal 63 to the CPU 51 via the switch input circuit 72. When the wincassette switch 70 is turned on, an operation start instruction is supplied from the CPU 51 to the winker relay 21, and the winker relay 21 intermittently turns on / off the contact. In accordance with this on / off, power is intermittently supplied to the left blinker lamps FL, RL, and the left blinker lamps FL, RL blink. At this time, the cancel relay 65 is on.

  Even when the driver changes the vehicle course to the right side, the wincassette switch 68 is switched to the individual contact side connected to the front right winker lamp FR and the rear right winker lamp RR. 70 is turned on and is input from the set signal terminal 63 to the CPU 51 via the switch input circuit 72. When the wincassette switch 70 is turned on, an operation start instruction is supplied from the CPU 51 to the winker relay 21, and the winker relay 21 intermittently turns on / off the contact. In accordance with this on / off, power is intermittently supplied to the right side blinker lamps FR, RR, and the right side blinker lamps FR, RR blink. When the blinker lamps FR, RR, FL, and RL are blinking, the blinker signal activates the blinker indicators, that is, the indicators 47b and 48b.

  Since the individual contacts of the first switch 67a of the hazard switch 67 are connected to all the blinker lamps FR, RR, FL, RL, when the hazard switch 67 is operated, all the blinker lamps FR, RR, FL , RL blinks.

  Among the blinker lamps FR, RR, FL, and RL, the front right blinker lamp FR and the front left blinker lamp FL also serve as position lamps. When the winker switch 67 is not operated, the common contact of the position switch 69 is in contact with two individual contacts at the same time, so the front winker lamps FR, FL are connected via the second switch 67b of the hazard switch 67. The power is connected to and turned on.

  When the blinker switch 68 is operated, the position switch 69 operates so that only one of the two individual contacts is selected and connected to the contact 67 b of the hazard switch 67. For example, when the winker switch 68 is switched to the individual contact side connected to the right winker lamps FR and RR, the common contact of the position switch 68 is separated from the individual contact connected to the front right winker lamp FR. The right side blinker lamp FR is turned off as a position lamp. When the winker switch 67 is switched to the individual contact connected to the left winker lamps FL and RL, the common contact of the position switch 68 is separated from the individual contact connected to the front left winker lamp FL. The left blinker lamp FL is stopped from lighting as a position lamp. Thus, since the position lamp does not light up when the blinker switch 68 is operated, the blinker display can be clearly performed.

  In addition, when the hazard switch 67 is turned on, that is, when the first switch 67a of the hazard switch 67 is turned on, the second switch 67b is turned off. Canceled. Therefore, the hazard lamp display can be clearly performed.

  When the winker switch 68 is operated and the CPU 51 recognizes that the winker operation is started by turning on the wincassette switch 70, the CPU 51 starts a determination process for stopping the winker operation. The blinker operation is stopped when it is determined that the vehicle has finished changing the traveling direction. The completion of the traveling direction change is, for example, that the rudder angle detected by the rudder angle sensor 16 has returned to the straight traveling angle, or that the vehicle speed detected by the vehicle speed sensor 26 has exceeded a predetermined value. Etc.

  When the CPU 51 determines that the traveling direction change has been completed based on the steering angle, the vehicle speed, or the like, it outputs a cancel signal to turn on the switching element 73. Then, the coil portion of the cancel relay 65 is energized, the contact of the cancel relay 65 is turned off, and the blinker operation is stopped.

  When the coil portion of the cancel relay 65 is energized by the operation of stopping the blinker operation, the coil portion of the position relay 66 is also energized at the same time. However, the cancel relay 65 and the position relay 66 operate with opposite logic. When the blinker operation is stopped, the contact of the position relay 66 is turned on, and the front left blinker lamp FL and the front right blinker lamp FR are lit and act as a position lamp.

  Further, even when the contact portion of the cancel relay 65 is turned off by the blinker canceller function, the hazard switch 67 is connected to the flasher relay 21. Therefore, when the hazard switch 67 is turned on, the first of the hazard switch 67 is turned on. All the blinker lamps FL, FR, RL, and RR are connected to the blinker relay 21 via the switch 67a, and blink according to the intermittent state of the blinker relay 21.

  Further, since the contact of the winker cancel relay 65 is a normally closed contact, even if the winker canceler control function fails and the signal from the winker cancel signal terminal 64 cannot be output, this normally closed Since the blinker lamps FL, FR, RL, RR and the blinker relay 21 are connected via the contacts and the blinker switch 68, the original direction indicating function can be maintained.

  1 may be modified so that the cancel relay 65 is a normally open (normally open) contact and the position relay 66 is a normally closed contact. In this case, the logic of the winker canceller signal output from the CPU 51 when it is determined that the vehicle has completed the change in the traveling direction is inverted.

  In this way, during the blinker operation, the switching element 73 is turned on by the output of the CPU 51 and the cancel relay 65 is turned on. When the traveling direction method change is completed, the CPU 51 turns off the switching element 73 and turns the blinker. Stop operation. On the contrary, the position relay 66 is turned off during the blinker operation, and is turned on when the blinker canceller function is activated.

  As shown in the above embodiment, the winker relay 21 composed of a flasher relay is also used as a hazard relay, and the winker relay 21, that is, the flasher relay is connected to the winker switch 68 via a cancel relay 65 having a simpler configuration than the flasher relay. . As a result, it is possible to solve the problem that even the hazard function is stopped when the blinker is canceled without increasing the number of flasher relays. Further, even when a signal from the blinker cancel signal terminal is not output due to a failure, a robust system that can maintain the original direction indicating function can be realized.

  The CPU 51 in the display control device of the meter panel 12 has a winker canceller control function, an AD input circuit 71, a switch input circuit 72, a switching element 73, winker indicator circuits 47a and 48a, and light emitting diodes. 47b, 48b and the like were incorporated in the control device of the meter panel 12.

  However, the present invention is not limited to this, and the winker control function and the winker canceller control function are separately provided from the display control device. For example, the winker control function and the winker canceller control function are disposed in the vicinity of the rudder angle sensor 16, It may be integrated with the control device. Further, the type of the steering angle sensor and the attachment structure to the vehicle body are not limited to this embodiment, and a known algorithm for determining the blinker cancellation time can be used.
