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.
