Abstract

The application provides an engine control method for a fuel cell vehicle, and the method comprises the steps: obtaining the current temperature in a power cell; according to the current temperature,identifying the current temperature level of the vehicle; determining the target output power of a fuel engine according to the temperature grade, so that the electric quantity of the power battery iskept in a target interval, different temperature levels corresponding to different output powers; and adjusting the output power of the fuel engine to the target output power. The target output powerof the fuel engine on the vehicle can be determined on the basis of the current temperature grade of the vehicle, so that the output power of the engine can be dynamically adjusted according to different temperature grades, the influence of temperature factors on the output power of the engine is considered, and sufficient electric quantity of the power battery is ensured; therefore, the dynamicproperty requirement of the whole vehicle can be better met.

Description

technical field [0001] The present application relates to the technical field of fuel cell vehicles, in particular to an engine control method and device for a fuel cell vehicle and the fuel cell vehicle. Background technique [0002] Hydrogen fuel cell vehicles can achieve zero emissions, which is the future of new energy vehicles. From the national strategy to the development of the enterprise, the layout of the field of hydrogen energy vehicles has already begun. [0003] However, limited by the technical development of domestic hydrogen fuel cell engines, the real-time power of hydrogen fuel cell engines cannot follow the demand for vehicle power in time, and only works in the selected high-efficiency range. In a low temperature environment, the output power of the hydrogen fuel engine is low, which leads to the low SOC of the power battery, and its allowable discharge power cannot meet the power demand of the whole vehicle. Contents of the invention [0004] This ap...
