电动助力转向在环仿真试验台的开发.

To solve the problems of traditional vehicle EPS system performance test with long test period, high input cost and low efficiency, the experimental platform was redeveloped based on the TAT-6/TL type of electric power steering in the loop simulation test bench. According to the working characteristics and testing requirements of EPS system, the electric push rod loading device was selected, and the electric putter real-time control was realized based on the speed and steering wheel angle by MCS912 controller. The steering resistance was accurately simulated under different steering conditions. By the virtual test technology and EPS test bench, the debugging was conveniently and quickly realized to reduce the dependence on real vehicle test. The performance of the linear EPS system was verified by the resistance test of ground and steering condition, the current follower and the response characteristic test. The results show that the simulation and test results are basically consistent, which can meet the requirements of EPS performance test. [ABSTRACT FROM AUTHOR]
