However, the relation between the damping force generated by the damping mechanism and the pedal stroke is linear, that is, the damping force of the damping mechanism is related to the compression length, so that two different damping forces cannot be provided at the same position, and nonlinear adjustment cannot be realized. However, the force output by the drive motor 5 is independent of the pedal stroke, and the force output by the drive motor 5 can be set as needed, thereby achieving nonlinear adjustment of the pedal stroke and the load force (damping force generated by the damping mechanism and the drive motor). The realization of nonlinear adjustment can increase the dimension of the user for autonomously adjusting the pedal feeling, increase the adjustment of the pedal force and improve the user experience; in addition, frequent disassembly and assembly and mold opening periods can be omitted in the development process, different pedal feelings can be quickly switched, and development efficiency is improved.
