中文摘要：

针对新手开车误踩油门而经常产生严重交通事故现象，文章设计由急刹车误踩油门判断电路、单片机控制电路、继电器切断油门及驱动刹车等电路构成的急刹车误踩油门应急系统，能自动识别误踩油门，启动紧急刹车功能。实验表明系统易于实现并取得较好效果，具有广泛的应用前景。文中概述了系统的硬软件设计与具体实现方法。

英文摘要：

Aiming at the serious traffic accident phenomenon resulting from new driver false stepping on accelerator, an emergency system for false stepping on accelerator under abrupt halt which is composed of the judgment circuit of false stepping on accelerator under abrupt halt, MCU control circuit, throttle cutting off with relay, and drive brake circuit, etc. is designed. This system can identify false stepping on accelerator automatically, start the emergent brake function. The experimental results show that the system is easy to realize and achieve good results, and has a broad prospect of application. The design of hardware and software and the concrete realization method of the system are described in this paper.
