Design of the EPS motor automation test system

Abstract

The rapid global development of electric vehicles has heightened the imperative for exacting performance assessments of Electric Power Steering (EPS) systems, a pivotal subsystem within the automotive domain [13] . This research focuses on the EPS automated testing equipment as the research subject, proposing an automated testing system solution for EPS motors in new energy vehicles based on the testing requirements of the entire vehicle factory. The system is primarily composed of three parts: a testing platform, a control cabinet, and an industrial computer, incorporating both hardware devices and software programs. Its purpose is to conduct motor performance tests specifically tailored for EPS powerassisted motors. The testing system can achieve automated execution, data collection, and data analysis, displaying test results and saving test reports. Experimental findings affirm that the motor testing system demonstrates elevated stability and reliability, contributing significantly to the enhancement of testing efficiency and precision, as substantiated by relevant academic literature.
