New Control Algorithms for Steering Feel Improvements of an Electric Powered Steering System with Belt Drive

This contribution investigates an electric powered steering (EPS) system with belt drive of the company TRW Automotive GmbH, Dusseldorf (Germany), relating to new control algorithms for steering feel improvements. The EPS belt drive consists of an electric motor that transforms the assist torque with a belt and ballnut mechanism to power assist, which means to an assist force at the rack. The assist force at the rack is needed for the reduction of steering torques that are detected by the driver over the mechanical feedback of the assemblies pinion, torsion bar and steering column. Steering feel improvements are obtained with new torque control functions for a vehicle fitted with an EPS belt drive. Additionally, a simulation analysis of the steering system shows the improvements of the controller design process regarding to some specific steering manoeuvres. On the basis of subjective steering assessments, relations to the objective assessments are presented. The objective assessments are based on simulation results and vehicle measurements.
