The invention discloses a hydrogen reactor power-on and power-off control method suitable for a hydrogen reactor of a new energy commercial vehicle, relates to the field of new energy vehicles, and solves the problems of incomplete hydrogen reactor power-on and power-off control strategies, unclear hydrogen reactor power-on and power-off conditions and the like of an existing new energy commercialvehicle hydrogen reactor power-on and power-off control method. Power-on and power-off characteristics of the hydrogen reactor are combined to optimize and perfect the power-on and power-off controlscheme of the hydrogen reactor. d Real vehicle detection verification on the optimized power-on and power-off control scheme is optimized, and the control scheme and the technical parameters are continuously optimized. According to the method, the hydrogen reactor power-on condition is defined, and the new energy commercial vehicle hydrogen reactor power-on control strategy is perfected and optimized. Repeated power-on and power-off of the hydrogen reactor are avoided, and reliability and service life of the hydrogen reactor are not affected. A hydrogen reactor power-off control strategy is optimized and perfected, and the problems that in the hydrogen reactor power-off process, purging of a hydrogen reactor is not completed, and high-voltage power-off is conducted are solved. The safety of the whole vehicle and the hydrogen reactor is ensured. The new energy hydrogen fuel commercial vehicle adopting the hydrogen reactor power-on and power-off control method is reliable in operation, and no hydrogen reactor power-on and power-off faults occur.
