A Study on Acceleration Slip Regulation of Electric Drive Vehicle Based on Road Identification

摘要

In order to improve the dynamic performance of vehicle driven by in-wheel motor, the acceleration slip regulation (ASR) is established based on the road identification. The ASR control adopted a slip mode control method based on the road's optimal slip rate and designed an abnormal fault detector based on CUSUM algorithm. The optimal estimation of slip rate can be realized based on the figure and the filtering algorithm. This kind of control is proven by a real-time simulation in the (HIL) Hardware In Loop in order to improve the vehicle's performance including the directly accelerating ability. It can also help the vehicle to cross road obstacles better.
