The invention provides an automobile electronic brake power assisting device. A return spring is arranged between the outer side of the rear end of a rack shaft and a shell, the rear portion of the rack shaft is of a hollow pipe structure, the front end of a brake ejector rod is arranged in a hollow pipe of the rack shaft, a certain gap is formed between the front end of the brake ejector rod and the closed end of the hollow pipe of the rack shaft, a spring seat is arranged on the brake ejector rod, an ejector rod return spring is arranged between the spring seat and the shell, and the rear end of the brake ejector rod is connected with a brake arm movable pin. A pedal position sensor is arranged on a brake arm rotating shaft, the controller controls output torque of the motor according to signals of the pedal position sensor, and the signals of the pedal position sensor are in direct proportion to the output torque of the motor. And a brake lamp switch is used for assisting when the pedal position sensor fails.

    一种汽车电子制动助力装置,齿条轴后端外侧与外壳之间设置回位簧,齿条轴后部为空管结构,制动顶杆前端设置在齿条轴空管内,制动顶杆前端与齿条轴空管封闭端设置一定的间隙,制动顶杆上设置弹簧座,弹簧座与外壳之间设置顶杆回位簧,制动顶杆后端与制动臂活销连接。制动臂旋转轴上设置踏板位置传感器,控制器根据踏板位置传感器信号,控制电机的输出扭矩,踏板位置传感器信号和电机输出扭矩成正比。制动灯开关在踏板位置传感器失效时进行辅助助力。
