The invention provides a driving anti-skid rotating speed control method for a distributed driving electric vehicle. A rotating speed control intervention judgment device, a rotating speed control quit judgment device and a rotating speed controller are included. The judging device is used for judging whether the number of slipping wheels and the multi-wheel slipping duration exceed corresponding threshold values or not; when not activated, the rotating speed controller tracks the accelerator pedal to analyze the vehicle speed and calculate the reference wheel speed; the larger value between the reference wheel speed calculated by the real vehicle speed and the reference wheel speed calculated by the set vehicle speed is tracked when activated. Compared with the prior art, according to the scheme, through accurate calculation, the problems that due to multi-stage transmission of a gearbox, a transmission system is greatly delayed, due to steep and rugged road surfaces, wheel loads are greatly changed, and the traditional driving anti-skid control effect is poor are solved; and the driving anti-skid capacity of the distributed driving electric automobile under the severe working condition is greatly improved.
本发明提供一种分布式驱动电动汽车驱动防滑转速控制方法,包括转速控制介入判断器、转速控制退出判断器、转速控制器。判断器以打滑车轮数目和多轮打滑持续时间是否超过对应阈值为条件;未激活时转速控制器跟踪油门踏板解析车速计算出的参考轮速;激活时跟踪真实车速计算的参考轮速与设定车速计算的参考轮速之间的较大值。与现有技术相比,本方案通过精准的计算,解决由于变速箱多级传动导致的传动系统存在较大延迟和由于路面陡峭崎岖导致的车轮载荷大幅度变化,导致的传统驱动防滑控制效果不佳的问题,极大程度提高恶劣工况下分布式驱动电动汽车的驱动防滑能力。
