The invention discloses an electric hydraulic power-assisted steering system of a new energy automobile and a control method of the electric hydraulic power-assisted steering system. The electric hydraulic power-assisted steering system comprises an electric control system and a mechanical system, and the electric control system controls work of the mechanical system; the electric control system comprises a whole vehicle network, a whole vehicle controller, an EHPS controller, a low-voltage power source, an ignition signal and a steering motor. The EHPS controller adjusts the current and the rotating speed according to current changes. The EHPS only needs to adjust the current and the rotating speed according to the current change, so that the steering requirement can be responded, the energy-saving purpose is achieved, the enabling and the rotating speed do not need to be controlled through a VCU like a traditional technology, and the situation that after information such as the angle and the torque is received, complex operation is conducted, and then motor output torque change is executed is avoided; the communication path is greatly shortened, the response time is prolonged, and the cost is reduced by reducing the number of sensors.

    本发明公开了一种新能源汽车电动液压转向助力系统及其控制方法,包括电控系统、机械系统,所述电控系统控制机械系统的工作;所述电控系统包括整车网络、整车控制器、EHPS控制器、低压电源、点火信号、转向电机,所述EHPS控制器根据电流变化调整电流、转速;本发明仅需EHPS根据电流变化调整电流、转速即可响应转向需求并实现节能的目的,不需要像传统技术一样通过VCU控制使能和转速,也不需要接收角度、扭矩等信息后进行复杂运算后再执行电机输出扭矩的变动;极大的缩短了通讯路径、提高了响应时间,且通过减少传感器减少了成本。
