Regenerative braking control strategy of four-wheel drive electric vehicle considering road identification
摘要
Abstract
To make full use of road adhesion conditions for distributing regenerative braking force and improving braking energy recovery,the braking energy recovery control strategy of dual-motor four-drive electric vehicle composite braking system was investigated according to the braking system characteristics.A road identifier was designed to calculate the peak adhesion coefficient between each tire and the current road surface,and a fuzzy control strategy was used to determine the similar input of slip rate and adhesion utilization ratio between each wheel and 8 kinds of roads.According to the braking force distribution relationship of the external characteristics of dual motors,a strategy was proposed to make more braking energy return to the battery.The results show that when the braking intensity is 0.3,the energy recovery rate is 65.55%,which has high recovery efficiency.关键词
