The invention provides a control method of a fuel cell vehicle and a vehicle control unit. The method comprises the steps: a trigger instruction of a hybrid mode switch is received; the allowable continuous charging power of a power battery is obtained; if the allowable continuous charging power is greater than or equal to the idling power generation power of a fuel cell engine, the fuel cell engine is started; if the allowable continuous charging power is smaller than the idling power generation power and the power battery is in a heating state, heating power is obtained; if the sum of the heating power and the allowable continuous charging power is greater than or equal to the idling power generation power, the fuel cell engine is started; whether the fuel cell engine meets a preset shutdown condition or not is determined; and if the fuel cell engine meets a preset shutdown condition, the fuel cell engine is stopped. According to the scheme, the battery state of the power battery isfully considered when the fuel battery engine is started and stopped, and the hybrid driving mode is prevented from being directly started or kept for a long time, so that the charging safety of the power battery and the dynamic property of the whole vehicle are ensured.
本发明提供了一种燃料电池汽车的控制方法及整车控制器，该方法为：接收混动模式开关的触发指令；获取动力电池的允许持续充电功率；若允许持续充电功率大于等于燃料电池发动机的怠速发电功率，启动燃料电池发动机；若允许持续充电功率小于怠速发电功率且动力电池处于加热状态，获取加热功率；若加热功率与允许持续充电功率之和大于等于怠速发电功率，启动燃料电池发动机；确定燃料电池发动机是否符合预设的停机条件；若燃料电池发动机符合预设的停机条件，停止燃料电池发动机。本方案中，在启停燃料电池发动机时充分考虑动力电池的电池状态，避免直接启用混动驱动模式或长时间保持混动驱动模式，从而保证动力电池的充电安全和保证整车的动力性。
