Abstract
The invention relates to a method that permits the determination of a steering-wheel torque for the steering wheel of a motor vehicle. A steering angle is predefined by the driver for the steered wheels by means of the steering wheel. A steering torque that represents the forces on the vehicle axis acts on the steering wheel. According to the invention, a manual torque (M_desired) is determined using at least one axle model. The manual torque is then superimposed on the steering-wheel torque M_actual).
Claims15
A method for determining a steering torque for the steering wheel of a motor vehicle, wherein a steering angle for the steered wheels is predefined by the driver by means of the steering wheel using a continuous mechanical connection between the steering wheel and the steered wheels with a steering-wheel torque which represents the forces on the vehicle axle being active, said steering-wheel torque being caused as a result of the continuous mechanical connection existing between the steering wheel and the steered wheels and wherein a manual torque (M_soll) which is superimposed on the steering-wheel torque (M_ist) is determined using at least one axle model.
