The invention relates to the technical field of vehicle control technologies, in particular to an IPB and EHPS or EPS safety redundant system which comprises an IPB, an RBU and an EHPS or EPS, a transmission mechanism is provided with an EHPS hydraulic pump on a hydraulic power-assisted steering pipeline and is driven by an EHPS motor to achieve hydraulic power-assisted steering or is directly connected with an EPS motor to achieve electric power-assisted steering. The RBU motor serves as an IPB redundant standby motor and is connected with the IPB motor through a CAN, the IPB motor is provided with an IPB motor fault monitoring module, the EHPS motor or the EPS motor is connected with the RBU motor through the CAN, the EHPS motor or the EPS motor is provided with an EHPS motor fault monitoring module or an EPS motor fault monitoring module, and the RBU motor serves as a redundant standby 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.
