摘　　要：为提高汽车智能化,保护人们的生命财产安全,智能汽车防撞系统必不可少。文章设计的汽车防撞智能系统采用单片机STC89C52为主控芯片,通过红外传感器和超声波传感器双传感器进行测距,以保障检测的精确性。当检测到物体与车的距离小于设定的阈值时,系统进行声光报警并显示距离,同时主动采取有效干预模式控制汽车减速或紧急刹车,有效防止了车辆碰撞。In order to improve the vehicle intelligence and protect people?s life and property, the intelligent vehicle anti-collision system is essential. The intelligent vehicle anti-collision system designed uses STC89C52 MCU as the main control chip, and the infrared sensor and ultrasonic sensor used for ranging so as to guarantee the accuracy of detection.When the distance between the object and the car is detected to be less than the set threshold value, the system alerts through sound and light, displaying the distance, and at the same time, actively takes an effective intervention mode to control the deceleration or emergency braking of the vehicle, thus effectively preventing vehicle collision.
