摘要
针对电动商用车在低附路面ABS激活后制动平顺性较差的问题,设计基于滑移率和ABS的制动性能控制系统。系统在ABS激活前通过调节制动扭矩,降低ABS激活概率;在ABS激活后通过控制电制动取消速率,并耦合正常状态电制动MAP,从而改善制动平顺性。
Aiming at the problem of poor braking smoothness of electric commercial vehicles after ABS activation on low adhesion roads,this paper designs a braking performance control system based on slip ratio and ABS.The system reduces the probability of ABS activation by adjusting the braking torque before ABS activation.After ABS activation,the braking smoothness is improved by controlling the electric braking cancellation ratio and coupling the normal state electric braking MAP.
