Problems solved by technology

At present, the start and stop of the fuel cell is mainly based on the current driving mode, the power requested by the power system, the allowable output power of the power battery and other thresholds to judge the timing of the start and stop of the fuel cell. If the driver's driving habits are poor, it will cause the fuel cell to start and stop too frequently , will not only consume too much power of the power battery, but also affect the life of the fuel cell

Abstract

The invention relates to the technical field of vehicle control, and provides a method and device for controlling a fuel cell of a vehicle. The vehicle includes a fuel cell and a power battery, and the method includes: detecting road condition information of a planned driving route of the vehicle; detecting the electric quantity of the power battery; and controlling according to the road condition information and / or the electric quantity of the power battery Startup or shutdown of the fuel cell. The invention can save the electric energy of the power battery and prolong the service life of the fuel battery.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, and in particular, to a method and device for controlling a fuel cell of a vehicle. Background technique [0002] The fuel cell (such as hydrogen fuel cell) vehicle will involve the start and stop of the fuel cell during use. At present, the starting and stopping of fuel cells are mainly based on the current driving mode, the power requested by the power system, the allowable output power of the power battery and other thresholds to determine the timing of starting and stopping the fuel cell. If the driver has poor driving habits, it will cause the fuel cell to start and stop too frequently. , not only will consume too much power battery power, but also affect the life of the fuel cell. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a control method for a fuel cell of a vehicle, so as to save the electric energy of the power battery and...
