The invention relates to a double-electric-drive-axle vehicle driving control method based on the slip rate, and the method is applied to a 6 * 4 vehicle model and comprises the steps that rotating speed signals of a front axle, a middle axle and a rear axle are obtained; according to the rotating speed signals of all the axles, the initial slip rates of the middle axle and the rear axle relative to the front axle are determined; obtaining a vehicle load state and/or current road condition information, wherein the road condition information at least comprises a road slope; based on the vehicle load state and/or the current road condition, the initial slip rates of the middle axle and the rear axle are corrected, and the actual slip rates of the middle axle and the rear axle are obtained; according to the actual slip rates of the middle axle and the rear axle, a drive control strategy is determined, and the drive control strategy at least comprises the torque distribution proportion of the middle axle and the rear axle.
本发明涉及一种基于滑移率的双电驱桥车辆驱动控制方法,应用于6×4车型,方法包括:获取前桥、中桥及后桥的转速信号;根据各桥的转速信号,分别确定中桥和后桥相对于前桥的初始滑移率;获取车辆载重状态和/或当前路况信息,路况信息至少包括路面坡度;基于车辆载重状态和/或当前路况,对中桥和后桥的初始滑移率进行修正,得到中桥和后桥的实际滑移率;根据中桥与后桥的实际滑移率,确定驱动控制策略,驱动控制策略至少包括中桥与后桥的扭矩分配比例。
