The invention provides a hydrogen energy automobile fuel cell engine back pressure valve self-learning calibration method and system. The zero position (initial position) and the full-open position ofa back pressure valve can be self-adaptively corrected in the whole life cycle, and repeated calibration is not needed; and when the valve plate of the back pressure valve has a clamping stagnation phenomenon, a back pressure valve driving motor completes a repairing function of the clamping stagnation phenomenon of the back pressure valve plate through large duty ratio impact.
本发明提供了一种氢能汽车燃料电池发动机背压阀自学习标定方法及系统;背压阀零点位置(初始位置)和全开位置可以在整个生命周期内完成自适应修正,无需重复标定;当背压阀阀片出现卡滞现象,背压阀驱动电机通过大的占空比冲击,完成背压阀片卡滞现象的修复功能。
