A power source 27 such as a battery is connected to one end of the potentiometer 21, and a movable contact 21a slides against a sliding resistance 21b in accordance with relative movement between the vehicle body and a movable part including a handle, etc. It is installed so that its position can be changed, and a voltage signal corresponding to the steering wheel turning angle is output to A.
/D converter 22. The steering wheel turning angle input as a voltage signal to the A/D converter 22 is
After being converted into a digital signal by 2, it is output to the microcomputer 23.

A steering wheel switch 24 and a vehicle speed sensor 25 are connected to the microcomputer 23, and the microcomputer 23 receives information such as the steering angle from the A/D converter 22, the state of the steering wheel switch 24, and the vehicle speed from the vehicle speed sensor 25. Based on this calculation, a blinker cancel signal is output from the output terminal 26 when a predetermined condition is met.

[Problem to be solved by the invention]

However, with the above-mentioned conventional automatic turn signal canceling device, the automatic turn signal canceling device does not operate unless the turning angle of the steering wheel exceeds a certain level. There is a problem in that when the vehicle is tilted to turn without turning the turn, the automatic turn signal canceling device does not operate and the turn signals are not automatically canceled.

The present invention has been developed in view of the above-mentioned problems, and an object of the present invention is to provide an automatic turn signal canceling system that can operate even when the vehicle turns due to only the inclination of the vehicle body.

[Means to solve the problem]

In order to solve the above problems, the present invention provides a motorcycle equipped with a microcomputer that turns on and off blinkers based on predetermined conditions such as the steering wheel turning angle, the state of the handlebar switch, and the vehicle speed detected by the vehicle speed sensor. blinker
The cancellation device includes a photosensor having a light-emitting element and a light-receiving element, and a shielding plate that moves between the light-emitting element and the light-receiving element of the photosensor according to the inclination of the vehicle body, and passes or blocks light from the light-emitting element to the light-receiving element. A vehicle body tilt detection sensor is provided to detect the tilt of the vehicle body, and the output of the vehicle body tilt detection sensor is added as a condition for turning on and off the blinker.

[Effect]

By configuring the automatic blinker cancellation system as described above, a vehicle body tilt detection sensor is provided and the output of the vehicle body tilt detection sensor is added as a condition for turning on and off the blinker, so the steering wheel turning angle is small and the turning radius is small. The turn signal is automatically canceled even when cornering with a large angle or high speed, eliminating the conventional problem of forgetting to return the turn signal.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a circuit diagram showing the configuration of an automatic blinker canceling device for a motorcycle to which an automatic blinker canceling system according to the present invention is applied. As shown in the figure, the automatic blinker canceling device includes a microcomputer 1, a steering wheel switch 2, a vehicle speed sensor 3, a steering wheel turning angle detecting section 4, an inclination sensor 5, an A/D converter 6, and an output section 7. There is.

The steering wheel switch 2 is composed of an ON switch 2a and an OFF switch 2b, the vehicle speed sensor 3 is composed of a reed switch 3a and a magnet 3b, and the tilt sensor 5 is composed of a light emitting element 5a, a shielding plate 5b, and a light receiving element 5c. ing.

The outputs of the ON switch 2a, OFF switch 2b, reed switch 3a, and light receiving element 5c are input to the input terminals T1, T2, and T of the microcomputer 1, respectively.
1, connected to T. Output section 7 is resistor R1
and a transistor TR, and is connected to an output terminal T of the microcomputer 1. Further, the + side of a battery (not shown) is connected to the input terminal T, and a blinker lamp (not shown) is connected to the output terminal T. In Fig. 1, R1 to R8° are resistors, C1 to C6 are capacitors, Dt is a diode,
O20 is an oscillation element.

FIG. 3 is a diagram showing a schematic structure of the tilt sensor 5. The tilt sensor 5 has a supporting base 31 and a shielding plate 5b attached so that the light emitting element 5a and the light receiving element 5c (see FIG. 1) face each other as fulcrums. It is constituted by a support column 33 that is rotatably supported around a center 34. In the tilt sensor 5 horizontally attached to the body of a motorcycle, a fan-shaped shielding plate 33 rotates around a fulcrum 34 in accordance with the tilt of the vehicle body.

In order to detect the tilt of the vehicle body using the automatic turn signal canceling device shown in FIG. 1, it is determined whether the state of the input terminal T6 of the microcomputer 1 is at the H (high) level or the L (low) level. In other words, if the vehicle body is within a certain angle in the vertical direction,
The light from the light emitting element 5a is blocked by the shielding plate 5b, the light receiving element 5C is not activated, and the state of the input terminal T6 of the microcomputer 1 becomes H (high) level. Next, when the vehicle body tilts over a certain angle, the shielding plate 5b moves and the light emitting element 5
The input terminal T of the microcomputer 1 because the light from a passes through and activates the light receiving element 5C.

The state is L (low) level.

As mentioned above, since the signal at the input terminal T of the microcomputer 1 corresponds to the inclination of the vehicle body, the inclination of the vehicle body can be detected by sequentially monitoring the state of the input terminal T by the microcomputer 1. I can do it. The microcomputer 1 outputs an output terminal T based on the vehicle body inclination information from the inclination sensor 5 and information from the steering wheel switch 2, vehicle speed sensor 3, and steering wheel turning angle detection section 4.

By setting the output terminal to H (high) level and lighting up the blinker lamp, or setting the output terminal T to L (low) level,
Turn off the blinker lamp. For example, even if the steering wheel turning angle is not above a certain level according to the output from the steering wheel turning angle detection section 4, the vehicle body is within a certain angle in the vertical direction, the light from the light emitting element 5a is blocked by the shielding plate 5b, and the light receiving element 5c is Microcomputer 1 not working
When the state of the input terminal T becomes H (high) level, the output terminal T is set to L (low) level and the blinker lamp is turned off.

In the above embodiments, the structure of the tilt sensor 5 is merely an example, and it goes without saying that the structure is not limited to the above structure as long as the tilt sensor detects the tilt of the vehicle body.

〔Effect of the invention〕

As explained above, according to the present invention, the automatic turn signal canceling device is provided with a vehicle body tilt detection sensor that detects the tilt of the vehicle body, and the output of the vehicle body tilt detection sensor is transmitted to the turn signal canceling device.
This is added as a condition for turning on and off the lights, so even when cornering with a large turning radius or high speed cornering where the steering wheel turning angle is small, the turn signal is automatically canceled due to changes in the lean angle of the vehicle, preventing you from forgetting to return the turn signal. You can get excellent results.
