摘　　要：主要对新能源汽车防追尾预警刹车功能进行了优化设计。基于汽车防撞模型对车辆的制动过程进行了分析,并在此基础上构建了一种防追尾预警刹车系统。该系统基于AT89S52,在汽车的行驶过程中对前方车辆状态进行实时检测,能够准确判断出安全制动距离系统声光预警模块,在发现其对本车构成危险时会向驾驶员及时发出提示、给出预警界限,根据实测距离和自车车速协助驾驶员及时采取刹车等措施,从而使车辆追尾情况得以有效避免。This article mainly optimizes the design of the anti-collision warning brake function of new energy vehicles,analyzes the braking process of the vehicle based on the vehicle anti-collision model,and builds on this basis an anti-collision warning brake system.Based on AT89S52,real-time detection of the state of the vehicle in front of the car during the driving process can accurately determine the safety brake distance system,sound and light early warning module will prompt the driver and give an early warning when it finds that it poses a danger to the car.Based on the measured distance and the speed of the vehicle,the system can assist the driver to take timely measures such as braking so that the rear-end situation of the vehicle can be effectively avoided.
