A power steering system includes a steering shaft, a linkage assembly, a first power assist assembly, and a second power assist assembly. The linkage assembly includes an input member drivingly connected to the steering shaft and an output member adapted to be drivingly connected to steerable wheels. The first power assist assembly is drivingly connected to the steering shaft and is arranged to apply a torque to the steering shaft to supplement a driver input force and change the direction of the steerable wheels. The second power assist assembly includes an electric motor drivingly connected to one of the steering shaft and the linkage assembly. The electric motor is arranged to apply torque to the steering shaft or the linkage assembly to change the direction of the steerable wheels with or without a presence of the driver input force to the steering shaft.
