摘　　要：驾驶汽车过程中,错踩油门(油门当刹车),引发的交通事故屡见不鲜。本设计结构根据驾驶员紧急制动时,踩踏刹车踏板的力远远大于踩踏油门踏板力这一事实,从而导致节气门开度不同,通过传感器测量误踩油门时节气门开启的角度、角速度、角加速度这三个参数的模拟量,并将信号传到控制器,与试验得到的临界值比较,判断是否误踩油门,若是,则发送命令到执行器进行强制制动,防止此类交通事故的发生。In car driving,it is not rare to witness accidents caused by accelerating by mistake（mistaking accelerator for brake）.This structure according to the driver when the emergency brake,depress the brake pedal force is far greater than the stampede of the fact that the accelerator pedal power and thus lead to different throttle mistakenly stepped on the accelerator throttle angle sensor measurement, angular velocity,angular acceleration analog of these three parameters and signals in the controller, compared with the critical value to determine whether mistakenly stepped on the accelerator,and if so, to send commands to force the brake actuator to prevent the occurrence of such accidents.
