摘　　要：为了避免误把油门当刹车的操作,减少恶性交通事故发生,设计了基于车载CAN总线的智能刹车系统。该系统以PIC18F258单片机为核心,根据对油门踏板的上下限时间差,判断出把油门当刹车的误操作,通过车载CAN总线以报文的形式发送给车载网络上的相关控制单元,使汽车自动刹车;并给出了系统的硬件电路和软件设计流程。In order to avoid the misuse of throttle and brake and to reduce the vicious traffic accidents, intelligent braking systems is designed based on vehicle CAN bus in the paper. PIC18F258 microeontroller is used as the core of the system. According to time difference of up and down limit on the gas pedal, it determines the error operation of braking and sends messages to network-related vehicle control unit through the vehicle CAN bus, to stop the car automatically. The hardware circuit and software design process is given in the paper.
