Many drivers turn off their headlights to prevent over-discharging or to be considerate of oncoming and preceding vehicles, but sometimes they forget to turn on their headlights when they start driving again. There is a problem that in urban areas, etc., people may not notice that the headlights are turned off. In addition, in a control device like the latter that automatically turns on and off the headlights, the headlights are turned off when the vehicle is stopped, so they are unnecessarily turned on during traffic jams where the vehicle starts and stops repeatedly. The problem is that the lights repeatedly turn off, which is not only troublesome, but also inconvenient because the lights are turned off even when the driver does not want them to be turned off.

The present invention was made in order to solve the above-mentioned problems, and it is possible to arbitrarily turn off the headlights when the vehicle is stopped, and if the headlights are turned off, they are automatically turned on when the vehicle starts driving. It is an object of the present invention to provide a control device for a headlight for a vehicle, and a control device for a vehicle headlight that allows selection of either manual operation or automatic operation for turning on and off the headlight.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a headlight switch that instructs turning on and off the headlights, a vehicle speed sensor that detects vehicle speed, and a headlight switch that instructs the headlights to turn on and off; A lights-off switch that only instructs to turn off the lights; and a lights-off switch that controls turning on and turning off the headlights according to the turning-on and turning-off operations of the headlight switch; the vehicle stops with the headlights on, and the lights turn off. a control circuit that turns off the headlamp when a switch instructs the headlamp to turn off, and turns on the headlamp when the vehicle starts and receives a driving signal from the vehicle speed sensor; A headlight switch for instructing to turn on or off the headlights, a selection switch for selecting automatic or manual operation of the headlights, a vehicle speed sensor for detecting vehicle speed, and the selection switch for manual operation. When selected, the headlights are turned on and off in accordance with the operation of the headlight switch, and when the selection switch is selected for automatic operation and the headlights are turned on, the vehicle speed sensor stops the headlights. The vehicle is configured to include a control circuit that turns off the headlight when a signal is input and turns on the headlight again when the vehicle starts and a running signal is input from the vehicle speed sensor.

(Function) When the vehicle is stopped with the headlights on, when the driver operates the lights-off switch, the headlights are temporarily turned off. When the vehicle is started with the headlights turned off, the control circuit receives a signal from the vehicle speed sensor and turns on the headlights. Thereby, even if the driver starts the vehicle with the headlights turned off, the headlights can be turned on.

In addition, when the driver selects manual operation of the selection switch, the headlights can be turned on and off according to the operation of the headlight switch, and when the driver selects automatic operation, the headlights turn on and off when the vehicle is stopped. It is turned off and turned on when driving. This allows the headlights to be turned on even when the vehicle is stopped.

This headlight switch 1 outputs a signal Sa (Fig. 3 (a)) when the knob 1a is set to the headlight ON position (hereinafter simply referred to as the ON position), and stops outputting the signal Sa when set to the OFF position. do.

Lights off switch switch lO is knob 1 of headlight switch 1
It is a switch exclusively for turning off the headlights 1 and 1, which is provided so as to protrude from the end face of the headlight a. This light-off switch 10 is composed of a push button type normally open switch, which is closed when pressed and outputs an open signal Sc (FIG. 3(C)) for a certain period of time, and when the pressing force is released, it is opened and outputs the corresponding signal. Stops the output of Sc. Each contact of the headlight switch 1 and the lights-off switch 10 are connected to a control circuit 11, respectively.

Vehicle speed sensor 2 detects the speed of the vehicle and outputs a signal S when the vehicle is running.
b (Fig. 3)), and when stopped, the output of the signal sb is stopped.

The control circuit 11 controls the headlights to be turned on and off based on signals input from the headlight switch 1 , the light-off switch 10 , and the vehicle speed sensor 2 . When the control circuit 11 receives the signal Sa from the headlight switch l, the control circuit 11 receives the control signal Sd (third
(d)), and when the input of the signal Sa is stopped, the output of the control signal Sd is stopped. That is, the control circuit 11
outputs a control signal Sd in response to the on/off operation of the headlight switch l and stops. Further, the control circuit ti receives the signal Sc output from the lights-off switch IO only when the signal sb is not input from the vehicle speed sensor 2, that is, when the vehicle is stopped, and the signal Sa is input from the headlight switch 1. Even if the signal Sa is in use, the output of the control signal Sd is stopped in priority to the signal Sa, and when the vehicle starts and the signal sb is input from the vehicle speed sensor 2, the control signal Sd is output again.

The relay 4 is connected to the output terminal of the control circuit 11, and operates to close the contact when the control signal Sd is applied from the control circuit 11, and opens the contact when the control signal Sd is not applied.

When the selection switch 12 is selected for manual operation, the control circuit 13 controls the headlights 5.5 to be turned on and turned off in response to the turning on and turning off of the headlight switch 1, regardless of whether the vehicle is running or stopped. However, when the selection switch 12 is set to automatic operation, when the vehicle stops with the headlights 5.5 on and no signal is input from the vehicle speed sensor 2, the headlights 5.5 are turned off. The headlights 5.5 are then turned on again when the vehicle starts traveling again from this off state and a signal is input from the vehicle speed sensor 2.

If the driver wishes to keep the headlights 5.5 on when the vehicle is stopped, this can be achieved by selecting manual operation with the selection switch 12; Sometimes the headlights 5.5 are automatically turned off,
If it is desired to automatically turn on the headlights 5.5 again while driving, this can be achieved by selecting automatic operation with the selection switch 12. That is, the driver can select either manual or automatic operation.

(Effects of the Invention) As explained above, according to the present invention, there is provided a headlight switch that instructs turning on and off the headlights, a vehicle speed sensor that detects the vehicle speed, and an instructing only to turn off the headlights. The headlights are controlled to be turned on and off in accordance with the on and off operations of the headlight switch and the headlight switch, and when the vehicle is stopped with the headlights on and the headlights are instructed to be turned off by the light off switch. By including a control circuit that turns off the headlight when the vehicle is stopped and turns on the headlight when the vehicle starts and receives a running signal from the vehicle speed sensor, the driver can arbitrarily turn the headlight on when the vehicle is stopped. In addition to being able to turn off the headlights, the headlights can be automatically turned on even if the vehicle is driven with the headlights turned off, and the headlights are turned off when the vehicle is stopped and the vehicle is started. Lighting operations that are sometimes easily forgotten can be performed automatically.

Further, a headlight switch for instructing the headlights to turn on or off, a selection switch for selecting automatic or manual operation of the headlights, a vehicle speed sensor for detecting vehicle speed, and the selection switch include: When manual operation is selected, the headlights are turned on and off according to the operation of the headlight switch, and when the selection switch is selected for automatic operation and the headlights are turned on, the vehicle speed is changed.
