The invention relates to a limp control method and device for a vehicle, the vehicle and a storage medium, and the method comprises the steps that a fault signal of the vehicle is received; a corresponding limping mode is matched based on the fault type of the fault signal, and the power constraint of the vehicle is determined through the theoretical power parameters of the vehicle, preset safety limiting conditions and the fault signal; and a vehicle speed limiting threshold value of the vehicle is obtained in combination with the power constraint and the limping mode, and the vehicle is controlled to execute the limping mode based on the vehicle speed limiting threshold value. Therefore, the technical problems that in the related technology, the limp speed limit value cannot be accurately matched with the fault, so that extra loss is easily caused to the fault part or other power assembly parts when the vehicle is in the limp mode, and large potential safety hazards exist are solved.

    本申请涉及一种车辆的跛行控制方法、装置、车辆及存储介质,其中,方法包括:接收车辆的故障信号;基于故障信号的故障类型匹配对应的跛行模式,并利用车辆的理论动力参数、预设安全限制条件和故障信号确定车辆的动力约束;结合动力约束和跛行模式得到车辆的车速限制阈值,并基于车速限制阈值控制车辆执行跛行模式。由此,解决了相关技术中,导致跛行限速值无法与故障进行准确匹配,使得车辆在跛行模式下,易对故障部件或其它动力总成部件造成额外损失,存在较大的安全隐患的技术问题。
