The brake pedal simulator comprises a mounting base, a pedal, a pedal supporting arm, an adjusting connecting rod, a crank, a pressure sensor arranged in the pedal, a servo motor and a controller, the pedal is arranged on the pedal supporting arm, the pedal supporting arm is hinged to the mounting base, and the pedal supporting arm, the adjusting connecting rod and the crank are sequentially hinged to form a crank rocker mechanism. The controller is connected with the pressure sensor and the servo motor, the crank is connected with an output shaft of the servo motor, the servo motor is used for driving the crank to do circular motion relative to the mounting base, and the controller converts a pressure value into a real-time travel value of the pedal according to the pressure value collected by the pressure sensor and a preset brake pedal feeling curve; the force transmission mechanism is controlled to drive the pedal to move. The brake pedal simulator disclosed by the invention can provide rich brake foot feeling changes for a driver. The invention further discloses a control method of the brake pedal simulator, and the accuracy of pedal resetting and the consistency of brake experience in the long-term use process can be improved.

    本发明公开了一种刹车踏板模拟器,包括安装座、踏板、踏板支臂、调节连杆、曲柄、设于踏板内的压力传感器、伺服电机和控制器,踏板设于踏板支臂上,踏板支臂与安装座铰接,踏板支臂、调节连杆、曲柄依次铰接构成曲柄摇杆机构,控制器与压力传感器、伺服电机相连,曲柄与伺服电机的输出轴连接,伺服电机用于驱动曲柄相对于安装座做圆周运动,控制器根据压力传感器采集的压力值和预设的制动踏板感曲线将压力值转化为踏板的实时行程值,控制力传动机构带动踏板运动。本发明公开的刹车踏板模拟器能够提供给驾驶员丰富的刹车脚感变化。本发明还公开了一种刹车踏板模拟器的控制方法,有利于提高长期使用过程中踏板复位的精准性和刹车体验的一致性。
