Abstract

The invention relates to the technical field of hydrogen energy automobiles, in particular to a gear shifting system of a fuel cell hydrogen energy automobile. The gear shifting system comprises a vehicle control unit, a gear switch, a brake pedal, a hydrogen fuel cell system, a power battery management system, a high-voltage distribution box, a driving system and an HMI display screen. The gear shifting system of the fuel cell hydrogen energy automobile is complete in function, all the control units cooperate with one another to jointly complete the function of the gear shifting system, and very high stability and reliability are achieved; the HMI display screen can prompt that the gear shifting operation is forbidden under the working condition which does not conform to gear shifting, a driver is informed that the gear shifting operation under the current working condition is allowed, wrong vehicle operation caused by incomplete information prompt of the driver is prevented, and the vehicle safety is improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy vehicles, in particular to a gear shift system and a control method for fuel cell hydrogen energy vehicles. Background technique [0002] With the vigorous promotion of hydrogen fuel cells, the application of hydrogen energy vehicles is becoming more and more extensive. Compared with traditional fuel vehicles, the gear shifting strategy of hydrogen vehicles is different. If the gear shifting operation of traditional fuel vehicles is directly applied to hydrogen vehicles, it will cause the vehicle to be prone to gear shifting problems during use. The driver is a bit of a bother. Contents of the invention [0003] In view of this, the present invention provides a gear shifting system and a control method for a fuel cell hydrogen energy vehicle. [0004] The invention provides a gear shifting system and a control method for a fuel cell hydrogen energy vehicle, which mainly includes the fo...
