Abstract

The invention discloses a vehicle on-board light control system and method, wherein the vehicle on-board light control system comprises a controller, a brake, a light, and a power supply Vcc. The power supply Vcc, the brake and the light are all connected with the controller. The vehicle on-board light control system is characterized in that further comprises an auxiliary circuit comprising resistors R1, R2, R3, R4, wherein one end of the resistors R1, R2, R3 is connected in parallel with the power source Vcc; one end of the resistor R2 is grounded; the resistance of the resistor R2 is four times that of the resistor R1, and the resistance R2 is equal to the resistance of the resistors R3 and R4, and the auxiliary circuit is a TTL non-gate circuit.

Description

technical field [0001] The invention relates to vehicle lighting control, in particular to a vehicle lighting control system and method. Background technique [0002] Car lights are various traffic lights installed on cars to ensure safe driving. There are two types of lights and signal lights. From 1905 to 1912, in order to solve the front road lighting, the spotlight type acetylene headlights were first installed, and a kerosene lamp was equipped as the rear license plate light. From 1945 to 1947, the various exterior lamps that must be equipped at a minimum have been finalized. Qualified automotive lamps should meet the corresponding photometric, chromatic and basic environmental test specifications. [0003] Car headlights and car LED daytime running lights, as the eyes of a car, are not only related to the external image of a car owner, but also closely related to safe driving at night or in bad weather. The use and maintenance of car lights cannot be ignored. [0...
