The invention provides an automatic escape method and device for a vehicle and the vehicle, and the method comprises the steps: determining whether the vehicle meets the condition of starting an automatic escape function or not when it is determined that rear wheels of the vehicle slip; and if yes, an automatic escape function is started, the driving mode of the vehicle is controlled to be switched into a four-wheel-drive driving mode, and the vehicle is controlled to escape in the four-wheel-drive driving mode. When the rear wheels of the vehicle slip, if the vehicle meets the condition of starting the automatic escape function, the automatic escape function is started, so that the driving mode of the vehicle is switched into the four-wheel driving mode, front axle power is used for assisting the vehicle in escape, the driving force of the vehicle is increased, and the problem that the vehicle is trapped due to insufficient driving force caused by slip of the rear wheels of the vehicle is avoided; therefore, the driving safety is improved while the vehicle is out of trouble.
本发明提出一种车辆自动脱困的方法及装置和车辆,方法包括:确定车辆后轮打滑时,判断车辆是否满足开启自动脱困功能的条件;若是,开启自动脱困功能,控制车辆的驱动模式切换为四驱驱动模式,以在四驱驱动模式下,控制车辆脱困。本发明在车辆后轮打滑时,若车辆满足开启自动脱困功能的条件,则开启自动脱困功能,以将车辆的驱动模式切换为四驱驱动模式,利用前桥动力辅助车辆脱困,增加车辆驱动力,避免车辆后轮打滑导致的驱动力不足而被困的问题,从而在实现车辆脱困的同时,提高行车安全性。
