The invention discloses a hydrogen fuel cell vehicle starting control method. The control method comprises the steps that power-on awakening and self-checking are conducted on a vehicle control unit VCU; turning on an ignition switch, checking whether an upper high-voltage condition is met or not, displaying fault information by the instrument if not, and displaying high voltage success by the instrument if the upper high-voltage condition is met; the hybrid switch is pressed down to enter a hydrogen fuel cell starting mode, and is not pressed down to enter a pure electric driving mode; judging whether the temperature of the power battery cell is greater than T0, entering a hydrogen fuel cell normal-temperature starting mode if the temperature is greater than or equal to T0, and entering a hydrogen fuel cell low-temperature starting mode if the temperature is less than T0; t0 is a preset temperature value; by improving the starting control method of the hydrogen fuel cell automobile, the starting control method of the hydrogen fuel cell automobile can be more efficient and reliable, the starting requirements of the hydrogen fuel cell automobile in all temperature environments can be met, the power battery is not charged after starting, and the performance and the service life of the power battery are not affected.
本发明公开了一种氢燃料电池汽车起动控制方法,控制方法包括:对整车控制单元VCU进行上电唤醒与自检;打开点火开关,检查是否满足上高压条件,不满足上高压条件仪表显示故障信息,满足上高压条件仪表显示高压成功;按下混动开关进入氢燃料电池启动模式,不按下即进入纯电行驶模式;判断动力电池电芯温度是否大于T0,大于等于T0即进入氢燃料电池常温启动模式,小于T0即进入氢燃料电池低温启动模式;T0为预设温度值;本申请通过对氢燃料电池汽车起动控制方法的改进,能使氢燃料电池汽车起动控制方法更加高效、可靠,可满足氢燃料电池汽车各个温度环境下的起动要求,且起动后不给动力电池充电,不影响动力电池的性能及使用寿命。
