Optionally, the load reduction adjustment is performed on the power of the fuel cell engine based on the relationship between the speed regulation braking power demand of the driving motor and the set charging power of the power cell, and includes:
the speed regulation braking power demand of the driving motor is smaller than the set charging power of the power battery, and after a gear shifting allowing instruction sent by the vehicle control unit is received, the power of the fuel battery engine is reduced to the difference between the set charging power of the power battery and the speed regulation braking power of the driving motor;
if the speed regulation braking power requirement of the driving motor is larger than the set charging power of the power battery, after a gear shifting allowing instruction sent by the vehicle control unit is received, the power of the fuel battery engine is reduced to the minimum stable power of the fuel battery engine.
Optionally, the speed regulation braking power demand of the driving motor is less than the set charging power of the power battery, and after receiving the shift-allowed instruction sent by the vehicle controller, the power of the fuel cell engine is reduced to the difference between the set charging power of the power battery and the speed regulation braking power of the driving motor, including:

In a specific example, as shown in fig. 1, the transmission upshift process is divided into several stages, such as torque reduction, gear disengagement, speed regulation, gear entering, and torque slowing, and when there is an upshift request from the transmission, the following control logic is executed to adjust the power of the fuel cell engine:
a) And if the speed regulation braking power requirement of the driving motor is smaller than the difference between the set charging power of the power battery and the generating power of the fuel battery, keeping the power of the engine of the fuel battery unchanged in the gear shifting process.
b) If the speed regulation braking power demand of the driving motor is larger than the difference between the set charging power of the power battery and the power generation power of the fuel battery, and the speed regulation braking power demand of the driving motor is smaller than the set charging power of the power battery, after the vehicle control unit is allowed to shift, the power of the fuel battery engine is reduced to the difference between the set charging power of the power battery and the speed regulation braking power of the driving motor at the fastest speed, and if the difference between the set charging power of the power battery and the speed regulation braking power of the driving motor is smaller than the minimum stable power of the fuel battery engine, the power of the fuel battery engine is reduced to the minimum stable power of the fuel battery engine at the fastest speed.
