Abstract
The invention relates to a control method for a steering system having electric power assistance, comprising a control means, for example a steering wheel, which can be controlled by a driver, an electric power-assistance motor, an electric control unit, which contains a memory for storing digital data, a motor driver unit (motor controller), which determines electrical signals for controlling the power-assistance motor in accordance with a target motor torque that was transmitted to the motor driver unit and outputs said electrical signals to the power-assistance motor, at least one sensor device for determining a control variable, for example a manual torque, introduced into the control means, wherein a specification value for a motor torque of the power-assistance motor is determined in the control unit with the aid of the control variable, wherein in addition, an upper limit for the target motor torque is stored in a limiting element, and for a case A in which the specification value exceeds the upper limit, the limiting element outputs the upper limit as a target motor torque to the motor driver unit, and for a case B in which the specification value does not exceed the upper limit, the limiting element outputs the specification value as a target motor torque to the motor driver unit.
