Embodiment Construction

[0026] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0027] like figure 1 As shown, the present invention discloses a control method for automatically turning off the headlights of automobiles, which specifically includes the following steps:

[0028] (1) Monitor to determine whether the car is in a state of flameout: if it is determined that the car is not flamed off, go to step (1); if it is determined that the car is in a state of flameout, go to step (2).

[0029] In step (1), it is judged whether the car is in a state of flameout by reading the engine speed sensor: if it is judged that the generator speed is greater than zero, it means that the car has not been turned off, there are occupants in the car, and there are still people using car headlights at this time. It is possible, so the occupants in the car can actively judge whether it is necessary to turn off the headlights to save the pow...

The invention discloses a control method for automatically turning off an automobile headlamp. The control method includes the steps: (1) monitoring and judging whether an automobile is switched off or not, continuing the step (1) if the automobile is not switched off, and shifting to the step (2) if the automobile is switched off; (2) judging whether an automobile door lock is locked or not, shifting to the step (3) if the automobile door lock is locked, and continuing the step (2) if the automobile door lock is not locked; (3) judging the on-off state of the automobile headlamp, shifting to the step (1) if the automobile headlamp is turned off, and shifting to the step (4) if the automobile headlamp still works; (4) cutting off a power supply of the headlamp by a control system. By the control method, the automobile headlamp can be automatically turned off when not in use, and unnecessary trouble of an automobile owner can be decreased. Besides, by the aid of pre-existing equipment of an existing vehicle, the whole device is simple in structure, low in cost and applicable to most vehicles.

Description
