Method for controlling power steering of motor vehicle, involves controlling level of power steering by taking into account reference speed, which is highest of values of vehicle speed and nominal speed
The method involves comparing vehicle speed information (Vveh) with nominal speed (20), which is a product of rotational speed (Vmot) of an engine multiplied by a value of a reduction gear ratio. A level of power steering (28) is controlled by taking into account a reference speed (26), which is highest of values of the vehicle speed and nominal speed, where the level of power steering forms a decreasing function compared to the reference speed, and the level of power steering control varies between 100 and 30 percent of maximum torque. An independent claim is also included for a motor vehicle.
