Fuel cell automobile network architecture

Abstract

The invention provides a fuel cell automobile network architecture. The fuel cell automobile network architecture comprises a gas-electricity function controller, an isolation gateway, an instrument gateway and an instrument display. The isolation gateway is connected with a controller local area network bus of the fuel cell vehicle and the gas-electricity function controller, and the controller local area network bus is isolated from the gas-electricity function controller. The instrument gateway is respectively connected with the isolation gateway, a controller local area network bus of the fuel cell automobile, the instrument display and an instrument in the fuel cell automobile, and the instrument gateway is used for transmitting controller information of the fuel cell automobile. And the instrument display is used for displaying controller information of the fuel cell vehicle. The fuel cell automobile network architecture has system reliability and flexibility.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of vehicle development, and more specifically, relate to a fuel cell vehicle network architecture. Background technique [0002] The development cycle of a car generally takes three to four years, while some car show or rehearsal projects need to complete all work such as prototype car design, controller development, and vehicle debugging within one year. The cycle and range of changes are relatively limited. [0003] Compared with traditional vehicles, fuel cell vehicles have increased the functions of fuel cell vehicles. It is necessary to retain the control strategy of traditional vehicles and increase the management of power sources such as fuel cell packs. Therefore, the bus network structure becomes complicated, and the original The network architecture cannot meet the requirements and requires rapid transformation. At the same time, the network architecture needs to h...

AI Technical Summary

Problems solved by technology

[0002] The development cycle of a car generally takes three to four years, while some car show or rehearsal projects need to complete the prototype design, controller development, and vehicle debugging within one year. The period and the range of changes have been greatly restricted

[0003] Compared with traditional vehicles, fuel cell vehicles have added fuel-electricity functions. It is necessary to retain the control strategy of traditional vehicles and increase the management of power sources such as fuel cell packs. Therefore, the bus network structure becomes complex, and the original The network architecture cannot meet the needs and needs to be quickly transformed. At the same time, the network architecture needs to have certain scalability and flexibility, and a reasonable layout of the network architecture needs to be considered

[0004] There are two main solutions at present: redesigning the network architecture of the vehicle to meet the needs of fuel cell vehicles. The disadvantage of the gas-fired part of the function is that the original car controller has been verified by various rigorous experiments, and the newly developed controller cannot meet the stable operation requirements in a short period of time and the cost is high
