The invention provides a pedal feeling simulation device and a control method thereof. The device comprises a brake pedal (3) and a U-shaped pin (406) connected with the brake pedal (3) and further comprises a shell (404), a rack (403) fixedly connected with the U-shaped pin (406), a motor (409) used for driving the rack (403) and a stroke sensor (405) used for generating pedal stroke signals according to displacement of the rack (403). The control method of the device comprises the following steps: enabling the stroke sensor (405) to generate a pedal stroke signal according to the displacement of the rack (403); calculating a target current of the motor (409) from the pedal travel signal; performing PID control on the target current and the actual current of the motor (409), and outputting a PWM wave to control the motor (409); and enabling the motor (409) to output torque to provide pedal effort to the rack (403). According to the invention, the pedal feeling can be realistically simulated.

    本发明提供一种踏板感模拟装置及其控制方法,该踏板感模拟装置包括制动踏板(3)和与所述制动踏板(3)连接的U型销(406),还包括壳体(404)、与U型销(406)固定连接的齿条(403)、用以驱动齿条(403)的电机(409)以及用以根据所述齿条(403)的位移产生踏板行程信号的行程传感器(405)。该装置的控制方法,包括:由行程传感器(405)根据齿条(403)位移产生踏板行程信号;根据踏板行程信号计算电机(409)的目标电流;将目标电流与电机(409)的实际电流进行PID控制,输出PWM波控制电机(409);电机(409)输出扭矩用以向齿条(403)提供踏板力。本发明可逼真地模拟踏板感。
