The invention discloses a vehicle collision safety control system and method and a vehicle. The system comprises a collision safety controller, a hydrogen system controller and a hydrogen leakage monitor. The collision safety controller is used for detecting a collision stress value of a target position of the vehicle and sending a collision fault signal to the hydrogen system controller when the collision stress value is greater than a preset stress value; the hydrogen leakage monitor is used for collecting leakage data of the hydrogen cylinder and sending the leakage data to the hydrogen system controller; the hydrogen system controller is used for sending a closing signal to a cylinder valve when the collision fault signal is received and determining whether the hydrogen cylinder is in an abnormal state or not based on the leakage data when the collision fault signal is not received, if the hydrogen cylinder is in the abnormal state, the closing signal is sent to the cylinder valve, and the closing signal is used for controlling the cylinder valve to be closed. According to the system, the safety of the vehicle hydrogen system can be improved by actively closing the hydrogen cylinder valve when the vehicle hydrogen system is possibly damaged due to collision at the target position of the vehicle.
本发明公开了一种车辆碰撞安全控制系统、方法及车辆,所述系统包括:碰撞安全控制器、氢系统控制器以及氢泄漏监测器;碰撞安全控制器,用于检测车辆目标位置的碰撞受力值,并在碰撞受力值大于预设受力值时,向氢系统控制器发出碰撞故障信号;氢泄漏监测器,用于采集氢气瓶的泄漏数据,并发送给氢系统控制器;氢系统控制器用于在接收到碰撞故障信号时,向瓶阀发出关闭信号,以及在未接收到碰撞故障信号时,基于泄漏数据确定氢气瓶是否处于异常状态,若为异常状态,则向瓶阀发出关闭信号,其中,关闭信号用于控制瓶阀关闭。该系统能够在车辆目标位置发生碰撞,可能出现车辆氢系统损坏时,通过主动关闭氢气瓶瓶阀,增加车辆氢系统安全性。
