Problems solved by technology
According to the current signal matching method, one signal only represents one function. In order to solve this problem, the high beam and overtaking signal gears can only be separated, and a new signal is added to the combination switch. This requires the redevelopment of the combination switch, which will cause additional development costs

Abstract
A control method for a vehicle combination lamp control system, the control system comprises a body control module, a vehicle lamp combination switch, and the second pin, the fourth pin, the eighth pin and the ninth pin of the vehicle lamp combination switch are respectively automatic Headlight AUTO switch pin, small light switch pin, low beam light switch pin, high beam switch pin, these pins and the light sensor are all connected to the signal input end of the body control module. The connection and combination of the feet form different working conditions and provide the combination information to the body control module, which not only ensures that the body control module can complete the corresponding control actions, but also does not require additional signal lines, which maximizes the versatility of the light combination switch.
Description
technical field [0001] The invention belongs to the technical field of automobile control, and in particular relates to a control method of an automobile combination lamp control system. Background technique [0002] Automatic headlights, also known as automatic induction automatic headlights, are equipped with a photosensitive control system for the front combination lights of the car. The body control module (BCM) judges the change of light brightness according to the light sensor, so as to control the function of automatically turning on or off the headlights. . The driver can avoid the process of looking for a switch when the headlight is needed, and at the same time, it can also avoid the driver forgetting to turn on the headlight at night or when the light is not good, thereby improving the driving safety. [0003] The traditional car headlight function consists of the following components: position light and high and low beam light switch (generally on the combinatio...
