The invention discloses a fault limp processing method and system for a hydrogen fuel cell vehicle, which are applied to control equipment. The hydrogen fuel cell vehicle comprises a hydrogen fuel cell system, an auxiliary energy device and a power part. The fault limp processing method comprises the following steps of S1, judging whether functions of parts are limited or not, if so, entering a step S2, or otherwise, entering a step S5, S2, judging whether the function of the power part is limited or not, if yes, entering the step S6, or otherwise, entering the step S3, S3, judging whether thefunction of the hydrogen fuel cell system is limited or not, if so, entering the step S6, or otherwise, entering the step S4, S4, judging whether the function of the auxiliary energy device is limited or not, if yes, entering the step S6, or otherwise, entering the step S5, S5, controlling the whole hydrogen fuel cell vehicle to run normally, and S6, controlling the whole hydrogen fuel cell vehicle to enter a limp mode.

    本发明公开了一种氢燃料电池车的故障跛行处理方法及系统,应用于控制设备中,氢燃料电池车包含氢燃料电池系统、辅助能源装置以及动力部件。本发明的故障跛行处理方法包括以下步骤:S1、判断是否部件功能受限,若是,则进入步骤S2,否则进入步骤S5;S2、判断动力部件是否功能受限,若是,则进入步骤S6,否则进入步骤S3;S3、判断氢燃料电池系统是否功能受限,若是,则进入步骤S6,否则,进入步骤S4;S4、判断辅助能源装置是否功能受限,若是,则进入步骤S6,否则,进入步骤S5;S5、控制氢燃料电池车整车正常行驶;S6、控制氢燃料电池车整车进入跛行模式。
