Abstract
A method for determining a driver torque of a power steering assembly for an electrohydraulic power steering system of motor vehicles, includes an input shaft for introduction of a driver torque, an output shaft for driving a steering linkage and a torsion bar between the input shaft and the output shaft for actuation of a rotary slide valve, an electric drive for electrical steering assistance, and a control unit for controlling the electric drive. The power steering assembly has a sensor arrangement on the torsion bar for actuation of the rotary slide valve. An actual torque is determined with the aid of the sensor arrangement. The control unit determines a driver torque with the aid of the actual torque.
