The invention discloses a hydrogen fuel cell automobile starting idle speed control strategy and system, and the method comprises the following steps: presetting an SOC threshold value, obtaining the SOC of a power cell after the automobile is started, enabling a fuel cell to enter a set near-zero power output state when the SOC of the power cell reaches a first threshold value, and enabling the fuel cell to be started again when the SOC of the power cell is lower than a second threshold value, and when the SOC of the power battery reaches a third threshold value, the fuel battery keeps low power output and enters an idle speed state, and the idle speed control strategy of the hydrogen fuel cell automobile is completed through the steps. According to the invention, the performance degradation caused by overhigh voltage of the electric pile in the idling process of the fuel cell automobile can be effectively reduced, and the consumption of hydrogen is reduced to a certain extent.

    本发明公开了一种氢燃料电池汽车启动怠速控制策略及控制系统,包括以下步骤:预设SOC阈值,获取车辆启动后的动力电池SOC,当动力电池SOC达到第一阈值,燃料电池进入设定的近零功率输出状态,当动力电池SOC低于第二阈值,燃料电池再次启动,进入正常功率输出状态,对动力电池进行充电,维持整车能量需求,当动力电池SOC达到第三阈值,燃料电池保持一个较低的功率输出,进入怠速状态,通过上述步骤完成氢燃料电池汽车怠速控制策略。本发明能有效降低燃料电池汽车怠速过程中电堆电压过高引起的性能衰减,并在一定程度上减少氢气的消耗。
