Abstract: While most passenger vehicles equipped with power steering systems are hydraulic power assisted, Electric Power Steering (EPS) systems are becoming wide spread since they can afford higher fuel efficiency. This paper develops an integrated simulation of an EPS control system with a full vehicle model. Using co-simulation technique, a full vehicle model interacting with EPS control algorithm is concurrently simulated on a single bump road condition. The effects of EPS on the vehicle dynamic behaviour and handling responses resulting from steer and road input are analysed and compared with proving ground experimental data. The comparisons show reasonable agreement on tie-rod load, rack displacement, steering wheel torque and tyre centre acceleration. This developed co-simulation capability may be useful for EPS performance evaluation and calibration as well as for vehicle handling performance integration.
