The invention discloses a redundant wheel speed detection device for a motor vehicle. The motor vehicle is provided with a sensor assembly used for collecting the wheel speed. Each sensor assembly comprises a wheel speed sensor installed on each wheel edge and a processing module electrically connected with each wheel speed sensor in the sensor assembly, each wheel speed sensor transmits an acquired wheel speed signal to the connected processing module, and the wheel speed detection device is characterized in that the number of the sensor assemblies is at least two. The redundant wheel speed detection device for the motor vehicle can ensure that the vehicle obtains an accurate state no matter whether a wheel speed sensing device of a wheel and a wiring harness of the wheel or a processingmodule of a wheel speed or a vehicle speed breaks down. By means of the structure, it is guaranteed that at least two wheel speed sensing devices are arranged on each wheel edge, and the wheel speed sensing devices are connected to the two processing modules respectively and operate independently.
