Abstract:
1. A method for compensating for drive influences of a drive train of a motor vehicle on an electric power steering system having a manual torque and a servomotor assisted torque, said method comprising the steps of: using an engine torque, an engine speed wheel speeds and a steering wheel angle of the motor vehicle in a simulation model of vehicle behavior; using the modeled vehicle behavior to predict drive influences on the electric power steering system for a predetermined time profile; calculating a compensation torque in response to the predicted influences; and applying the compensation torque to the servomotor assisted torque during the predetermined time profile such that the applied compensation torque is supported by the servomotor of the electric power steering system thereby making any disturbance that occurs as a result of the predicted drive influences imperceptible in the manual torque of the electric power steering system.
