The invention discloses a driving anti-skid control method and device for a double-electric-drive-axle commercial vehicle, relates to the technical field of new energy vehicles, and can solve the problems that in the prior art, when the double-electric-drive-axle commercial vehicle passes through a low-attachment road surface, mechanical braking and motor driving need to be coordinated in the control process, the control difficulty is large, many cooperative parts are needed, and the cost is high. And calibration is complex. According to the specific technical scheme, firstly, the wheel speed difference and/or the slip rate of each drive axle of a target vehicle are/is obtained; judging whether the target vehicle slips or not according to the wheel speed difference and/or the slip rate; if yes, driving of the drive axle is controlled for anti-skid treatment. According to the method, an independent driving anti-skid control module is not needed, the development cost is saved, the development period is shortened, the trafficability, stability and safety of the low-attached road surface of the vehicle are improved, the vehicle slip frequency is reduced, the service life of tires is prolonged, the after-sales maintenance cost of the vehicle is saved, the vehicle calibration complexity of the method is low, and the method is suitable for popularization and application. And the method has relatively high transportability.
本发明公开了一种双电驱桥商用车驱动防滑控制方法及装置,涉及新能源汽车技术领域,能够解决现有技术中双电驱桥车型在通过低附路面时控制过程需要机械制动和电机驱动协调工作,存在的控制难度大,需要协同零部件多,标定复杂的问题。具体技术方案为:首先获取目标车辆各驱动桥的轮速差和/或滑转率;然后根据轮速差和/或滑转率,判断目标车辆是否打滑;若是,控制驱动桥的驱动进行防滑处理。本发明无需单独的驱动防滑控制模块,节省了开发成本,缩短了开发周期,提升了车辆低附路面的通过性、稳定性及安全性,降低了车辆打滑频次,提升了轮胎的使用寿命,节约了车辆售后维护成本,且本发明方法的车辆标定复杂度较低,具备较强的可移植性。
