Fuel cell hydrogen energy automobile collision control system and method

Abstract

The invention provides a fuel cell hydrogen energy automobile collision control system and method. The fuel cell hydrogen energy automobile collision control system comprises a safety airbag collisionsensor, a safety airbag controller, a fuel cell controller (FCU), a hydrogen cylinder, a hydrogen cylinder valve and the like. When a vehicle is collided and the safety air bag pops up, the safety air bag collision sensor sends a collision signal to the safety air bag controller, then the safety air bag controller controls the safety air bag to pop up, and meanwhile, the collision signal is sentto the fuel cell controller (FCU) through the CAN bus, and the fuel cell controller controls the hydrogen cylinder valve port to be closed. The fuel cell hydrogen energy automobile collision control system has the beneficial effects that operation is easy, the hydrogen cutting-off speed is increased, the explosion risk during vehicle collision is reduced, the vehicle and personal safety is improved, and practicability and applicability are achieved.

Description

technical field [0001] The invention relates to the field of hydrogen energy vehicles, in particular to a fuel cell hydrogen energy vehicle collision control system and method. Background technique [0002] Since the hydrogen of a hydrogen fuel vehicle is stored in a gas storage tank, the pressure is generally ≥30Mpa. Once the vehicle collides, if the hydrogen pipeline is damaged and the hydrogen leaks, it is very easy to explode when encountering an open flame. Therefore, it is required to cut off the hydrogen as quickly as possible when the vehicle collides. Reduce the risk of explosion. At present, some hydrogen-fueled passenger vehicles on the market do not have the function of cutting off the hydrogen in the collision of the whole vehicle, which seriously affects the safety of the whole vehicle. There are also some hydrogen-fueled passenger vehicles that add an acceleration sensor to the vehicle controller for collision judgment, but the sensitivity is not high, and th...
