Abstract: To realize the vehicle automatic parking function, not only need the automatic parking assist module for reasonable parking path planning, but also need the electric power steering module for smooth steering output in order to create a good and comfortable automatic parking experience. Different roads, different scenes of parking performance are closely related to electric power steering (EPS) system automatic parking assist (APA) function. Whether the electric power steering system can meet the performance requirements of the whole vehicle automatic parking, the debugging and calibration of the steering system APA function module parameters are particularly important. The vehicle test shows that it can make the vehicle APA function of various performance indicators to be effectively improved by reasonable debugging optimization of the EPS system APA module parameters.
