Environmental perception sensors are produced during the evolution of automotive safety technology from passive safety to active safety. The main function of the perception sensor is to detect and recognize the surrounding environment of the vehicle, which can be regarded as the eyes of the vehicle. Different types of automotive intelligent driving perception systems have different applicable scenarios, limited scenarios, advantages and disadvantages, and costs, and they form a complementary relationship with each other. Environmental perception sensors capture external information and provide it to the car computer system for planning and decision-making, mainly including laser radar, car camera, millimeter wave radar, ultrasonic radar, etc. the
The car intelligent driving perception system is the perception layer of the car system, which converts real-world visual, physical, event and other information into digital signals, provides basic guarantee for the vehicle to understand the surrounding environment and formulate driving operations, and provides the decision-making layer of the advanced assisted driving system Provide accurate, timely and sufficient basis, and then the executive layer can make an accurate judgment on the safe driving of the car.
