An Architecture of Hardware and Driver in the Loop Simulation for Electric Power Assisted Steering System

• This paper introduces an architecture for virtual development of electric power assisted steering (EPAS) system, which is implemented at Volvo Cars. The architecture involves an EPAS power pack rig and driver in the loop, so engineers can test both the ECU software and electric motor on a virtual prototype vehicle. Eective results are shown for tests in low-mid frequency and at mid-high vehicle speed. Currently, the high frequency and low speed test is still challenging due to vibration and instability, which should be addressed by the control improvement.
