ABSTRACT
In recent years, with the continuous improvement of our economic strength, the number of resident motor vehicles has shown a rising trend. At the same time, the number of motor vehicles and motor vehicle drivers keeps increasing, the road traffic accidents caused by it also rise. Reducing road traffic accidents, reducing the severity of accidents and improving the safety performance of vehicles are the requirements of the majority of drivers, which further promotes the automobile manufacturers to produce vehicles with better safety performance. Automatic emergency braking is an important vehicle active safety technology. Research shows that it can avoid 27% of traffic accidents and reduce the degree of injury of personnel and vehicles in the event of accidents. Therefore, this paper studies the collision avoidance strategy of automatic emergency braking system. The design detects the obstacles in front of the vehicle through the ultrasonic wave, measures the speed value through the Hall sensor, realizes the automatic braking under the condition of close range through the distance and speed, adjusts the speed through the button, displays the measurement data through the LCD1602; The detection verifies the effectiveness of the collision avoidance strategy developed, and the results show that the above research can effectively avoid the occurrence of collision accidents or reduce the severity of collision accidents.
