The invention discloses a hydrogen energy vehicle gas leakage safety control system, which is composed of an ECU, an information display system, an air conditioning system A/C, a vehicle body controlsystem, a power battery system, a gas engine system, a driving system and a gas supply system. The ECU is a vehicle electronic control unit and is responsible for collecting data of gas concentrationsensors at different positions of a vehicle. According to a gas concentration detection result and different working conditions of a vehicle, an appropriate control strategy is adopted to issue different control instructions to different systems, and the ECU is a control unit of a gas power generation system and is one or two of an engine controller EMS, a vehicle control unit VCU and a fuel cellcontroller FCU. According to the system, when leakage occurs, different control modes are adopted according to different leakage positions, meanwhile, different safe driving control strategies are adopted in combination with different current running working conditions of the whole vehicle, from multiple aspects, different systems are coordinated in a unified mode, an automatic control mode is adopted, and the safety of the whole vehicle is guaranteed to the maximum extent.

    本发明公开了一种车辆氢能汽车燃气泄漏安全控制系统,由ECU、信息显示系统、空调系统A/C、车身控制系统、动力电池系统、燃气发动机系统、驱动系统和燃气供应系统组成,所述ECU为车辆电子控制单元,负责采集车辆不同位置的燃气浓度传感器数据,根据燃气浓度检测结果和车辆不同工况,采取合适的控制策略给不同的系统下达不同的控制指令,ECU是燃气发电系统的控制单元,为发动机控制器EMS、整车控制器VCU、燃料电池控制器FCU中的一种或两种。该系统在泄漏发生时,根据不同的泄露的位置采取不同的控制方式,同时结合整车当前不同的运行工况采取不同的安全驾驶控制策略,从多个方面、对不同的系统统一协调,采取自动控制方式,最大程度保证整车安全。
