Automobile headlamp automatic control system and method thereof

Abstract

The invention relates to the technical field of automobile headlamps, in particular to a system for realizing the automatic control of a headlamp by using a vehicle-mounted host and a method thereof.The system for realizing the automatic control of the headlamp by using the vehicle-mounted host comprises an automobile body controller, a navigation host and an automobile headlamp controller whichare connected to a BUS in parallel; the automobile body controller is used for outputting an automobile key gear signal and starting the navigation host according to the automobile key gear signal; the navigation host is used for setting an automobile headlamp starting condition, judging whether the current condition satisfies the set starting condition or not and outputting an instruction signalof turning on or turning off the automobile headlamp to the automobile headlamp controller according to a judging result; and the automobile headlamp controller is used for turning on or turning off the automobile headlamp according to the instruction signal input by the navigation host. According to the automobile headlamp automatic control system and the method thereof, through adoption of the technical scheme, the technical problems that the response of the headlamp is delayed and the cost of a light sensitive system is high because the existing automobile automatic headlamp is affected bya light sensor are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular to a system and method for realizing automatic control of headlights through a vehicle-mounted host. Background technique [0002] At present, the automatic headlights installed in most cars are often an important configuration used by manufacturers to widen the gap between high-end and low-end models. Many low-end models are not equipped with automatic headlights. [0003] The method of realizing the automatic headlights of the car is basically through the photosensitive control system. When the light is dimmed while the car is driving, the headlights will automatically light up, and they will automatically turn off when the light becomes brighter. It is worth mentioning that when entering the tunnel, the headlights will be turned on automatically after the light sensing system senses that the light is dimmed. Therefore, users still need to manually turn on the headlights in...
