The invention provides a creeping control method and system for a new energy vehicle. The creeping control method comprises the steps that a time and acceleration relation curve of the new energy vehicle is obtained; according to the time and acceleration relation curve of the new energy vehicle, an MAP graph of the new energy vehicle from the initial speed to the target crawling speed and acceleration is obtained; when the new energy vehicle enters a crawling mode, determining a target torque of the new energy vehicle based on the MAP of the new energy vehicle from the initial speed to the target crawling speed and acceleration, and performing crawling control on the new energy vehicle based on the target torque; through the target torque of the new energy vehicle, crawling control over the new energy vehicle is achieved, the ideal speed can be achieved, and stable and smooth running of the crawling speed can be controlled under different loads and different working conditions.

    本发明提供了一种新能源车辆蠕行控制方法与系统,包括:获取新能源车辆的时间与加速度关系曲线;根据所述新能源车辆的时间与加速度关系曲线,得到所述新能源车辆从起始速度到目标蠕行速度与加速度的MAP图;当所述新能源车辆进入蠕行模式后,基于所述新能源车辆从起始速度到目标蠕行速度与加速度的MAP图,确定所述新能源车辆的目标扭矩,并基于所述目标扭矩,对所述新能源车辆进行蠕行控制;本发明通过新能源车辆的目标扭矩,实现对新能源车辆的蠕行控制,能够达到理想速度能够在不同载重、不同工况下,控制蠕行车速稳定平顺的运行。
