Abstract

The invention relates to a vehicle lamp control device which comprises a vehicle lamp controller and an LED lamp panel, wherein the vehicle lamp controller and a whole vehicle are in LN communicationnetwork and are connected to a whole vehicle power supply; a thermistor is arranged in the LED lamp panel; and the LED lamp panel is connected to output pins of the vehicle lamp controller. The vehicle lamp control method comprises the following steps: under a normal work state of a vehicle lamp system, detecting LIN communication information, a temperature, input voltage of the whole vehicle as well as a temperature of the LED lamp panel by the vehicle lamp controller, and controlling the LED vehicle lamp to turn on or off by the LIN communication information of the whole vehicle; switching the vehicle lamp controller to a fault light mode from the normal work state if faults occur, controlling the LED vehicle lamp to turn off by the vehicle lamp controller, communicating and transmittingfault information to the whole vehicle, continuously detecting the fault information of the vehicle lamp controller by LIN communication until faults are eliminated, and switching back to the normalwork state. The vehicle lamp control device can timely check faults of the vehicle lamp system, and further analyzes the faults specifically.

Description
