The invention relates to the technical field of new energy vehicles, in particular to a pure electric vehicle driving anti-skid control method and device and a vehicle. Comprising the following steps that after a whole vehicle is powered on, when the vehicle is in a driving mode, the wheel speed is in a normal range, the absolute value of the front and rear wheel speed difference value is larger than a wheel speed difference value preset threshold value and the vehicle turns, influence factors are determined according to the steering wheel rotating angle and the whole vehicle speed; calculating the product of the influence factor and the driving torque; calculating the product of the influence factor and the driving torque and the minimum value of the basic torque and the sliding control adjusting torque, and taking the minimum value as the final driving torque; the adjustment of the driving torque by the basic torque is optimized, so that the adjustment of the driving torque is more accurate, the problem that the wheel continuously accelerates and slips on a low-attachment road surface is avoided, and the safety of the vehicle is improved.

    本发明涉及新能源汽车技术领域,具体为一种纯电动汽车驱动防滑控制方法、装置及车辆。包括如下步骤:整车上电后,当车辆处于驱动模式、车轮轮速处于正常范围内、前后轮速差值的绝对值大于轮速差值预设阈值且车辆转弯时,根据方向盘转角和整车车速确定影响因子;计算影响因子和驱动扭矩的乘积;计算影响因子和驱动扭矩的乘积、基础扭矩和滑动控制调节扭矩的最小值,并将最小值作为最终驱动扭矩;优化了基础扭矩对驱动扭矩的调节,使得对驱动扭矩的调节更准确,避免了在低附路面车轮持续加速打滑问题,提高了车辆的安全性。
