The invention belongs to the technical field of skid resistance of intelligent electric vehicles, and relates to a vehicle driving skid resistance control method and system and a vehicle, and the method comprises the following steps: determining a controllable moment limit value according to road conditions and the speed of the vehicle; according to the vehicle driving power and the motor external characteristic map, the target driving torque proportion under the external characteristics is obtained; judging whether the vehicle enters a driving anti-skid stage or not according to the wheel acceleration and the wheel slip rate; if not, the target driving torque proportion under the external characteristics is set as the target driving force proportion; if yes, according to a driving anti-skid strategy, calculating to obtain a target driving force proportion; and multiplying the controllable torque limit value by the target driving force proportion to obtain the target electromagnetic torque. The method gives consideration to the utilization of vehicle road state sensing information and the accuracy and real-time performance of anti-skid control.
本发明属于智能电动汽车防滑技术领域,涉及一种车辆驱动防滑控制方法、系统及车辆,包括以下步骤:根据路况和车辆的车速确定可控力矩限值;根据车辆驱动功率和电机外特性map图,获得外特性下目标驱动力矩比例;根据车轮加速度和车轮滑移率,判断车辆是否进入驱动防滑阶段;若否则将外特性下目标驱动力矩比例设置为目标驱动力比例;若是,则根据驱动防滑策略,计算得到目标驱动力比例;将可控力矩限值与目标驱动力比例相乘,得到目标电磁转矩。其兼顾对车辆道路状态感知信息的利用、以及防滑控制的准确性和实时性。
