According to the braking force control method based on the decoupling type braking system, during braking, the driving force output by power is detected in real time, and when the driving force is increased, the braking force adjusting strategy of the wheel end is activated, specifically, the braking system actively improves the braking force of the wheel end; a driving torque threshold value is set, when the driving torque exceeds the threshold value, the braking force starts to be compensated, and it is guaranteed that the whole vehicle still has the crawling function after the braking force is compensated. The method is used for solving the problems that when an engine of a vehicle equipped with a hydraulic torque converter is cold or at a 4L gear and the pedal travel is determined, braking force is insufficient, and a driver needs to continuously step on a brake pedal deeply, so that the pedal travel is too long or pedal force is large.
本发明一种基于解耦式制动系统的制动力控制方法,在制动时,实时检测动力的输出的驱动力,当驱动力增加时,激活轮端的制动力调整策略:制动系统主动提高轮端的制动力;制动系统不完全抵消所有的驱动力:设定一个驱动扭矩阈值,当驱动扭矩超过此阈值后,制动力开始补偿,保证在制动力补偿后整车仍具有蠕行功能。本发明用于解决装备液力变矩器的车辆在发动机冷机或4L档位时,在踏板行程确定时,制动力不足,驾驶员需要继续深踩下制动踏板造成踏板行程过长或踏板力大的问题。
