The invention discloses a vehicle wheel driving state monitoring method and device and a vehicle. The method comprises the steps that the wheel acceleration of a target wheel and the whole vehicle actual acceleration of the vehicle are calculated; according to the difference value between the wheel acceleration and the actual acceleration of the whole vehicle, the wheel acceleration difference of the target wheel is obtained; according to the comparison relation between the wheel acceleration difference and a preset acceleration difference threshold value, whether the target wheel is in a slip driving state or not is monitored, and when the target wheel is in the slip driving state, the required torque of a motor corresponding to the target wheel is reduced. By adopting the technical means of the embodiment of the invention, the accuracy of judging whether the wheels slip or not can be effectively improved, so that the accuracy of anti-slip control on the vehicle is improved, and the safe driving performance of the vehicle is optimized.

    本发明公开了一种车辆的车轮驱动状态监测方法、装置和车辆。所述方法包括:计算目标车轮的车轮加速度和所述车辆的整车实际加速度;根据所述车轮加速度与所述整车实际加速度的差值,得到所述目标车轮的车轮加速度差;根据所述车轮加速度差与预设的加速度差阈值的比较关系,监测所述目标车轮是否处于打滑驱动状态,当监测到所述目标车轮处于打滑驱动状态时,降低所述目标车轮所对应的电机的需求扭矩。采用本发明实施例的技术手段,能有效提高判断车轮是否打滑的精准性,从而提高对车辆的防滑控制的准确性,优化车辆的安全行驶性能。
