The invention relates to an emergency control method and device for a fuel cell vehicle, electronic equipment and the vehicle. The method comprises the steps that if a power battery of the vehicle breaks down or battery insulation breaks down, whether the vehicle meets an emergency mode starting condition or not is determined; in response to determining that the vehicle meets the emergency mode starting condition, controlling a loop between a driving system of the vehicle and a fuel cell to be closed and a loop between the driving system and a power cell to be disconnected; controlling the voltage of the fuel cell to rise to the minimum working voltage of the driving system, and limiting the current of the fuel cell to the minimum value; and in response to determining that the vehicle completes high-voltage power-on, controlling the fuel cell to generate power according to the whole vehicle power demand, and controlling the driving system to act according to the actual generated power of the fuel cell. Therefore, the fuel cell can independently supply power to the vehicle, so that the vehicle can realize emergency driving when the power cell fails or the insulation of the cell is abnormal, the reliability and the fault-tolerant rate of the vehicle are improved, and the use experience of a user is further improved.

    本公开涉及一种燃料电池车辆的应急控制方法、装置、电子设备和车辆。该方法包括:若车辆的动力电池故障或者电池绝缘故障,则确定车辆是否满足应急模式启动条件;响应于确定车辆满足应急模式启动条件,控制车辆的驱动系统与燃料电池的回路闭合、与动力电池的回路断开;控制燃料电池的电压上升至驱动系统的最低工作电压,并将燃料电池的电流限制在最小值;响应于确定车辆完成高压上电,根据整车功率需求控制燃料电池发电,并根据燃料电池的实际发电功率控制驱动系统动作。如此,能够通过燃料电池独立为车辆供电,使车辆能够在动力电池故障或者电池绝缘异常时,实现应急行驶,提高车辆的可靠性和容错率,进而提高用户的使用体验。
