Abstract:
A motor vehicle power steering system includes a hydraulic pump, an electric motor for driving the pump, and a control unit for controlling the electric motor. The control unit includes means for controlling the power supply voltage applied to the electric motor so that said voltage increases up to a maximum value when the load impedance decreases from its unloaded value, and is at a low value when said load impedance is in the vicinity of its unloaded value.
