EPS system is an indispensable component of intelligent driving vehicles and one of the modules with the highest safety level. In order to simplify the EPS system works in real-time dynamic torque measurement system hardware composition, increase torque measuring precision, reduce response time, this paper proposes a passive wireless type surface acoustic wave EPS torque measurement system using a microstrip antenna as a signal transmission antenna. HFSS 15.0 software is used to conduct 3 d modeling and simulation optimization for the structure of coaxial underplane fed microstrip rectangular antenna, solve the optimal structure size of the antenna, process the real antenna and build the torque test bench for the electric power steering system. The test results show that the SAW torque measurement system designed in this paper can meet the requirements of dynamic torque measurement when the vehicle is turning, which is easy to arrange, saves installation space and can transmit torque signal wirelessly. The research content of this paper can provide reference for the measurement of other dynamic performance parameters of intelligent driving vehicles.
