The invention relates to the technical field of automobile control, and particularly discloses a control method for vehicle escape, a vehicle and a storage medium. The control method for vehicle escape comprises the steps of acquiring the state information of a vehicle, and determining trapped wheels; acquiring the speed of the vehicle; if the vehicle speed does not reach the closing threshold value, a vehicle auxiliary escape system is started, an air spring on one side of a trapped wheel is inflated to the allowable maximum air pressure value, an air spring on an untrapped wheel on the other side is deflated to the allowable minimum air pressure value, and a rear wheel steering system drives rear wheels to adjust steering; and prompting a driver to control an accelerator pedal to perform driving force control on the vehicle until the vehicle is out of trouble. According to the control method for vehicle escape, the state that the vehicle is trapped can be actively recognized, the posture of the vehicle can be actively adjusted under the combined action of the air spring and the rear wheel steering system, more vehicle loads are distributed to the untrapped wheels, the turning angle of the rear wheels is actively controlled, the vehicle can be driven out of the pit ground more easily to escape, and the service life of the vehicle is prolonged. The technical requirements on the driver are reduced.

    本发明涉及汽车控制技术领域,具体公开了一种车辆脱困的控制方法、车辆及存储介质。车辆脱困的控制方法包括:获取车辆的状态信息,确定受困车轮;获取车辆的车速;若车速未达到关闭阈值,则启动车辆辅助脱困系统,对受困车轮一侧的空气弹簧充气至许用最大气压值,对另一侧未受困车轮的空气弹簧放气至许用最小气压值,后轮转向系统驱动后轮调整转向;提示驾驶员控制油门踏板对车辆进行驱动力控制至车辆脱困。本发明提供的车辆脱困的控制方法,能主动识别车辆遇困的状态,空气弹簧与后轮转向系统联合作用,主动调整车辆的姿态,以将更多的车辆载荷分配给未受困车轮,并主动控制后轮的转角,使车辆更容易驶出坑地脱困,降低了对驾驶员的技术要求。
