Calibration and Evaluation of Steering Wheel Torque Signal for EPS System

Abstract:

Electric power steering (EPS) uses an electric motor to assist the driver when he or she is driving, and the amount of assistance to be applied depends on steering wheel torque and driving conditions. So steering wheel torque is one of the most important signals which keep the EPS system working properly, and a steering wheel torque fault could be a disaster for whole vehicle security. The aim of this paper is to design a calibration and evaluation system of torque signal, which is utilized for function detection of steering wheel torque module in EPS systems. Firstly, the detection procedure is proposed according to detection requirement; Then hardware structure and software design of the detection system are introduced. Finally, an EMC (Electromagnetic Compatibility) problem is analyzed and a solution for the EMC problem is proposed to make the detection system working properly.
