The invention relates to a control method for a steering system with electric power assistance, comprising a steering wheel, an electric power assist motor, an electric control unit, which includes a memory for storing digital data, a motor driver unit which based on a target engine torque that is delivered to the motor driver unit, determines and sends out electrical signals for controlling the electric power assist motor, at least one sensor device for determining a control variable introduced into the steering wheel, for example a manual torque, wherein in the control unit with the help of the control variable a preset value is determined for a engine torque of the power assist motor, characterised in that in the memory an upper threshold value for the target engine torque is stored and for a case A, in which the preset value exceeds the upper threshold value, the control unit sends out the upper threshold value as the target engine torque to the motor driver unit and in a case B, in which the preset value does not exceed the upper threshold value, the control unit sends out the preset value as the target engine torque to the motor driver unit. |
