Research on anti-misoperation operation system for motor vehicle throttle and brake

为降低驾驶员因紧急情况误踩油门而引发交通事故的概率,提出了由信号采集单元、电子控制单元、执行单元三部分组成的机动车辆油门制动防误操作装置。当机动车驾驶员误踩油门踏板时,以油门踏板加速度、车辆与障碍物距离以及驾驶员瞳孔状态作为辨别参数,经过ECU计算,接通电子开关,从而启动怠速控制系统避免车辆非正常加速,语音报警系统同时进行安全提示。

In order to reduce the probability of traffic accident caused by the driver stepping on the throttle in an emergency,this paper presents an anti-misoperation device for throttle and brake of motor vehicles,which consists of three parts： signal acquisition unit,electronic control unit and execution unit. When the driver of a motor vehicle mistakenly steps on the accelerator pedal,the acceleration of the accelerator pedal,the distance between the vehicle and the obstacle,and the pupil state of the driver are taken as the distinguishing parameters. After ECU calculation,turn on the electronic switch. Thereby start the idle speed control system to avoid abnormal acceleration of the vehicle. The voice alarm system carries on the safety prompt simultane-ously.
