Apparatus capable of automatically shutting down automobile big lamp system and control method thereof

Abstract

The invention provides a device capable of turning off vehicle headlight system automatically and a method for controlling the same. The device is arranged on the control end of a relay in a headlight power supply circuit, and the headlight is controlled by controlling the on and the off of the relay. The device comprises a main processor, a power supply processing part, a signal inputting part, and a control signal outputting part. The control method is as follows: when an ignition key is turned off, a dipped headlight and a small light are allowed to be used through a high beam glittery switch and can be delayed to be turned off automatically. Because an intelligent circuit centering on the main processor is additionally arranged in the headlight power supply circuit, the power supply circuit can control the headlight after the ignition key is turned off so that the headlight can provide lighting in certain period of time and can be turned off automatically. Therefore, the device is convenient to park at night, caters for the psychology of people with increasingly higher requirements on vehicle intellectualization, and meets the market requirements.

Description

technical field [0001] The invention relates to a control device and a control method for an automobile headlight, in particular to a control device and a control method for an automobile headlight after the automobile is turned off. Background technique [0002] Car headlights (also known as headlights) are powered by batteries or car generators. They are controlled by the headlight control system. The headlight control system includes two parts: relay control and electronic control. The device for the relay to control the headlight is a combined switch, which is composed of a light switch, a relay and a dimmer switch. The dimming of the headlights is controlled by the dimmer switch. The electronically controlled headlight system mainly controls the dimmer switch. When meeting cars at night, the high beam is automatically changed to the low beam through the dimmer switch, and then the low beam is changed back to the high beam. . At present, the light switches of most car ...

AI Technical Summary

Problems solved by technology

At present, the light switches of most car lights at home and abroad can only simply control the lights to be turned off. Generally, after the car is turned off, the car headlights cannot be turned on again, or even if they can be turned on, they cannot be automatically turned off. This is less intelligent, and consumption of car electricity

When driving into the garage at night, the car light system cannot be turned on after the car is turned off, or even if it can be turned on, it cannot be turned off automatically, which brings great inconvenience to the car owner when entering and leaving the garage.

With the increasing popularity of automobiles, people have higher and higher requirements for automobile intelligence. The above-mentioned existing situation obviously cannot meet the market requirements.
