The invention provides a method and system for judging slipping of a vehicle and the vehicle. The method comprises the steps: acquiring current working parameters of an engine of the vehicle and theoretical working parameters of driving wheels of the vehicle; according to the current working parameters and the theoretical working parameters, determining the theoretical acceleration of a driving wheel of the vehicle; acquiring the actual acceleration of the driving wheel; and under the condition that the difference value between the actual acceleration and the theoretical acceleration is larger than a preset threshold value, determining that the vehicle is in a slipping state currently. Under the condition that the engine outputs the same driving force, if the difference value between the actual acceleration and the theoretical acceleration of the driving wheel is larger than the preset threshold value,the condition indicates that the resistance borne by the driving wheel is smaller than the resistance borne by the driving wheel without slipping, the condition indicates that the driving wheel is in the slipping state at present, and therefore the method accurately judges that the wheel is in the slipping working condition.

    本发明提供了一种判断车辆打滑的方法、系统及车辆,其中,所述方法包括:获取所述车辆的发动机的当前工作参数,以及所述车辆的主动轮的理论工作参数;根据所述当前工作参数以及所述理论工作参数,确定所述车辆的主动轮的理论加速度;获取所述主动轮的实际加速度;在所述实际加速度与所述理论加速度的差值大于预设阈值的情况下,确定所述车辆当前处于打滑状态。因为在发动机输出同样大小的驱动力下,若主动轮的实际加速度与理论加速度的差值大于预设阈值,则说明主动轮所受到的阻力比不打滑时所受到的阻力更小,表明主动轮当前处于打滑状态,从而准确判断出车轮处于打滑工况。
