The invention relates to the technical field of vehicle control, and provides a driving wheel rotating speed control method and system. The method comprises the steps that: whether a current vehicle condition meets a preset wheel speed control condition or not is judged, and if the current vehicle condition meets the preset wheel speed control condition, the following step is executed: a current rotating speed difference of two driving wheels connected to the same differential mechanism of a vehicle is obtained in real time, and under the condition that the current rotating speed difference islarger than a preset first threshold value, a torque value output by the vehicle is controlled to be reduced; and the driving wheel rotating speed of the vehicle is controlled based on the reduced torque value. According to the driving wheel rotating speed control method and system, damage and ablation of the differential mechanism are prevented.
本发明涉及车辆控制技术领域,提供一种驱动轮转速控制方法及其系统,该驱动轮转速控制方法包括:判断当前车辆情况是否满足预设的轮速控制条件,在判断结果为是的情况下,执行:实时获取连接在车辆的同一个差速器上的两个驱动轮的当前转速差,在所述当前转速差大于预设第一阈值的情况下,控制所述车辆输出的扭矩值降低;基于所述降低后的扭矩值控制所述车辆的驱动轮的转速。本发明防止差速器的损坏和烧蚀。
