The invention relates to the technical field of vehicle control technologies, in particular to an electronic booster and EHPS or EPS safety redundant system which comprises an electronic booster and an EHPS or EPS, a redundant backup motor driving hydraulic pump is communicated with an electronic booster redundant hydraulic pipeline, a first electromagnetic valve is installed on the electronic booster redundant hydraulic pipeline, and a second electromagnetic valve is installed on the electronic booster redundant hydraulic pipeline. According to the transmission mechanism, an EHPS hydraulic pump is installed on a hydraulic power-assisted steering pipeline and driven by an EHPS motor to achieve hydraulic power-assisted steering or the transmission mechanism is directly connected with an EPS motor to achieve electric power-assisted steering, and a redundant backup motor serves as an electronic booster redundant standby motor to be connected with the electronic booster motor. And the redundant backup motor is used as a redundant backup motor of the EHPS motor or the EPS motor and is connected with the transmission mechanism. The system is simple in structure, low in cost, small in occupied space and high in practicability and safety.

    本发明涉及车辆控制技术技术领域,尤其涉及电子助力器与EHPS或EPS安全冗余系统,包括电子助力器、EHPS或EPS,冗余备份电机驱动液压泵与电子助力器冗余液压管路连通,电子助力器冗余液压管路上安装有第一电磁阀,传动机构通过在液压助力转向管路上安装EHPS液压泵并经EHPS电机驱动实现液压助力转向或者是直接与EPS电机连接实现电动助力转向,冗余备份电机作为电子助力器冗余备用电机与电子助力器电机连接,冗余备份电机作为EHPS电机或EPS电机的冗余备用电机与传动机构连接。本发明提供的系统结构简单,成本低,且占用空间小,实用性及安全性比较强。
