The invention relates to a vehicle control method and device, a storage medium and a hybrid vehicle. The method comprises the steps that if a high-voltage interlocking fault is detected, whether a high-voltage contactor is in a closed state or not is detected, and when an engine does not work, the engine is controlled to be started; if the high-voltage contactor is in the closed state, whether the high-voltage contactor is disconnected or not is judged at least according to the current running state of the hybrid power vehicle, and the current running state is one of the starting state and the running state; and if the high-voltage contactor is determined to be disconnected, controlling the high-voltage contactor to be disconnected. Therefore, the probability of vehicle power failure caused by a high-voltage interlocking fault can be reduced, and traffic accidents and traffic jams caused by sudden power failure and parking can be reduced. In addition, when the vehicle has the high-voltage interlocking fault, if the engine does not work, the engine is controlled to be started. Therefore, when the vehicle is powered off, the vehicle can still be driven by the engine to run, so that the basic running function of the vehicle is ensured, and the public traffic safety is prevented from being influenced.
本公开涉及一种车辆控制方法、装置、存储介质及混合动力车辆。方法包括:若检测到高压互锁故障,则检测高压接触器是否处于闭合状态,在发动机未工作时,控制发动机启动;若高压接触器处于闭合状态,则至少根据混合动力车辆的当前运行状态,判定是否断开高压接触器,当前运行状态为启动状态、行驶状态中的一者;若确定断开高压接触器,则控制高压接触器断开。由此,可降低高压互锁故障导致的车辆断电的概率,从而可减少因突然断电停车导致的交通事故及交通拥堵。另外,在车辆发生高压互锁故障时,若发动机未工作,则控制发动机启动。这样,可在车辆断电时,仍然可以通过发动机驱动车辆行驶,从而保证车辆基本的行驶功能,避免影响公共交通安全。
