电动汽车 EPS 助力曲线设计与评价研究
Study on Design and Evaluation of Assisted Characteristics Curve for EPS
摘要
Abstract
We analyzed the assist characteristic of electric power steering of the vehicle.Under different speeds,the ideal steering wheel torque of driver was changed with the steering wheel angle and lateral acceleration.We studied the ideal steering wheel torque model and established the ideal steering wheel torque models in high and low speed range.The ideal steering wheel torque model parameters in low speed range and its influence factors were analyzed.The vehicle model was built by ADAMS /CAR and Matlab,and the speed responding assist characteristic curve of passenger car was drawn up,and then the process assisted characteristic curve of electric power steering system was formed.The result showed that the assist curve meets the requirements of the automobile steering characteristic.关键词
