【摘要】 为了有效防止汽车相撞的交通事故 ,设计了一种利用红外线发射与接收原理自动控制车辆刹车的电路系统。该系统在车速超过了某一预定值时便启动。启动后 ,若车辆在某一距离范围内遇到障碍物 ,该系统迅速发出刹车信号 ,并自动产生刹车动作。超出这一距离范围 ,则不起反应更多还原

【Abstract】 WT5”BZ]To avoid car crashes effectively, a circuit system is designed by using the principle of infrared emitting and receiving, which can automatically control the brake of vehicles This system starts working when the car speed exceeds a preset speed While working, it would send out braking signals and brake the car automatically under the condition that the car confronts obstacles in a certain distance Beyond this distance, the system will not react更多还原
