The invention discloses an electric power steering system of a refitted vehicle and a control method of the electric power steering system, the electric power steering system comprises a control module ECU and a torque sensor, the torque sensor sends detected steering of a steering wheel and the size of torque to the control module ECU, the system further comprises a vehicle speed simulation module, and the output end of the vehicle speed simulation module is connected with the control module ECU; the vehicle speed simulation module outputs a vehicle speed signal to the control module ECU; and the control module ECU is used for controlling a power-assisted motor of the electric power steering system to operate so as to provide assisting power. According to the invention, corresponding vehicle speed signal values can be represented in the CPU through different voltage signals in a knob switch mode according to the requirements of a user, and then different vehicle speed signal values are sent to the EPS through the CPU, so that the purpose that the power-assisted steering of the user can be autonomously adjusted is achieved; the method is suitable for refitting of the electric power assisting system which cannot directly modify the VCU of a refitted vehicle, and large modification of the ECU is avoided.

    本发明公开了一种改装车的电动助力转向系统及其控制方法,包括控制模块ECU、转矩传感器,所述转矩传感器将检测到的转向盘的转向以及转矩的大小发送至控制模块ECU中,所述系统还包括车速模拟模块,所述车速模块的输出端连接控制模块ECU;所述车速模拟模块输出车速信号至控制模块ECU中;所述控制模块ECU控制电动转向助力系统的助力电机运行提供助力。本发明可以根据用户的需求通过旋钮开关的方式通过不同电压信号来表征对应的车速信号值CPU中,然后由CPU发送不同的车速信号值EPS中,从而实现了用户的转向助力可以自主调节的目的,适用于改装车辆无法直接对VCU修改的电动助力系统的改装,避免了对ECU进行较大的改动。
