The invention discloses a redundant wheel speed processing system for a motor vehicle, which is characterized in that each wheel edge of the motor vehicle is provided with a sensor assembly for independently acquiring the wheel speed, each sensor assembly is connected with an ECU (Electronic Control Unit) through a signal line, two independent processing modules are arranged in the ECU, each sensor assembly is connected with the input end of a change-over switch, and the change-over switch is connected with the corresponding processing module. The output ends of the change-over switches are connected to the two processing modules respectively, the change-over switches are connected with the change-over controller, and the change-over controller outputs control signals to the change-over switches so that the change-over switches can be selectively connected with one of the processing modules. The redundant wheel speed detection system for the motor vehicle can ensure that the vehicle obtains accurate wheel speed and vehicle speed when the processing module or the wheel speed sensing device and the wire harness of the wheel have single-point faults, and the structure and the processing method can realize simple wheel speed redundancy and safe operation of automatic driving.
