Method for producing track feedback in steering system of vehicle, involves computing rack gear force and torsion bar moment based on torque of motor to generate track feedback within predefined frequency ranges

摘要

The method involves computing rack gear force and torsion bar moment based on the motor torque of motor. The track feedback is determined within first frequency range as a function of computed rack gear force and within higher frequency range as a function of torsion bar moment. The torsion feedback is generated by amplifying torsion bar moment. Independent claims are included for the following: (1) device for producing track feedback in steering system of vehicle; and (2) control device for producing track feedback in steering system of vehicle.
