The invention discloses a programmable logic device-based automotive headlight adaptive control system and a programmable logic device-based automotive headlight adaptive control method. The control system is provided with a main control module, wherein the input port of the main control module is connected with a light detection input module, the control port of the main control module is connected with a control switch module, the output port of the main control module is connected with a dimming control output module, the power supply port of the main control module is connected with a level converter, the level converter is connected with a fuse, and the fuse is connected with a storage battery. The main control module processes the acquired signals of the light detection input module, determines whether to call the control switch module according to the processing result, and sends instructions to the dimming control output module when the output state of the control switch module is high level so as to realize switching of high and low beam lights. The function of free transformation under intricate ray environments and the adaptive capacity in various states in the running process of an automobile are solved. The system has simple circuits, high integration degree and low manufacturing cost.
Description
technical field [0001] The invention relates to an adaptive control system and method for automobile headlamps based on programmable logic devices. Background technique [0002] Cars bring great convenience to people's lives, but traffic accidents seriously threaten people's lives and property safety. However, the proportion of traffic accidents at night accounts for 50% of the total number of accidents. Lighting is an important factor affecting driving safety. The headlight is an important device for the car to provide lane lighting for the driver at night or under conditions of low visibility, and it is also a light signal device for the driver to warn and communicate. [0003] At present, there is a certain relationship between road traffic safety accidents in China and drivers' awareness of driving safety. For example, when meeting cars at night, some drivers do not change the far and low beam lights or change them improperly because the far and near lights of the ready...
