System for automatically turning on fog lamps and position lamps of automobile in rainy and foggy weather

Abstract

The invention discloses a system for automatically turning on fog lamps and position lamps of an automobile in rainy and foggy weather, which comprises fog lamps, position lamps, a combined instrument module, as well as a rainfall sensor and an air humidity sensor both for sending a rainfall size and an air humidity value to an air conditioning module. The air conditioning module then sends relevant information to an automobile body control module; meanwhile, the automobile body control module compares the relevant information with a rainfall value, an air humidity value and an automobile speed value, which are set in the automobile body control module according to the collected automobile speed situation; and if the automobile speed is higher than the set automobile speed, and the rainfall value or the humidity value is greater than the set value, the automobile body control module drives to turn on the position lamps and the fog lamps. The system disclosed by the invention which efficiently utilizes existing configuration of the automobile has rational reconstruction, simple structure, convenient implementation and low cost, and can automatically turn on the fog lamps and the position lamps at the right time to guarantee driving safety; meanwhile, the system disclosed by the invention also can manually select to turn on or off the fog lamps and the position lamps according to practical needs of a driver to guarantee use diversity of the fog lamps and the position lamps. The system disclosed by the invention can be widely applied to various automobiles.

Description

technical field [0001] The invention relates to a system for automatically turning on lamps, in particular to a system for automatically turning on fog lights and position lights of automobiles in rainy and foggy weather. Background technique [0002] Automobile fog lights can illuminate farther and more eye-catchingly in rainy and foggy days, and play a very important role in improving vehicle safety performance and protecting driver safety. However, when it rains, the driver usually needs to manually turn on the fog lights or position lights.
