Problems solved by technology

Cars bring convenience to people’s travel, but they can also cause us troubles due to various reasons. When we go to the underground garage to pick up the car, we need to turn on the headlights, but we didn’t turn off the headlights when we got to the ground because we couldn’t see the lights during the day. The lights may be forgotten after a while. When we arrive at the destination, we turn off the car and leave the car, but the headlights are not turned off. When we finish our work and need to leave, we find that the car has no electricity and cannot start. This will be very troublesome.

Embodiment 1

[0022] Embodiment 1 of the present invention: a kind of method of automatically turning off the headlight of a car, when the car is turned off, the headlight is automatically turned off through the control of the on-board computer to the relay, and the steps include:

[0023] a. Detect whether the car key is pulled out;

[0024] b. If the result of step a is affirmative, then detect whether the time for pulling out the key reaches a predetermined value, otherwise repeat step a;

[0025] c. If the result of step b is affirmative, then detect whether the headlight is turned on, otherwise the control method is invalid;

[0026] d. If the result of step c is affirmative, the photosensitive sensor senses the light intensity and judges whether it is daytime, otherwise the control method is invalid;

[0027] e, if the result of step d is affirmative then will send signal to on-board computer;

[0028] f. The on-board computer sends a signal to the relay after processing the informa...
