摘要: 为了减少自动驾驶车辆行驶过程中由于故障导致的车辆失控、碰撞等安全问题,设计了一种自动驾驶车辆故障诊断系统.该系统采用萤火虫算法对车辆故障进行预判,实时诊断车辆发生的故障信息,按照故障对自动驾驶车辆安全行驶影响的严重程度进行分级,并按照安全防护等级,结合责任敏感安全(RSS)防碰撞模型下发不同的控制指令进行车辆控制,以达到安全行车的目的.实车应用结果表明,该系统可有效应对由于自动驾驶车辆故障导致的车辆失控、碰撞等安全问题,保证了自动驾驶车辆的安全运行.Abstract: In order to reduce the safety problems such as out of control and collision caused by vehicle faults during the driving of autonomous vehicle, a fault diagnosis system for autonomous vehicle was developed. The system used the firefly algorithm to predict vehicle faults, and diagnosed the faults all the time.It divided the faults into five levels according to the severity of the impact of faults on the safe driving of autonomous vehicle.Different control commands were issued according to the safety protection level and the responsibility sensitive safety (RSS) to ensure the safe operation of the vehicle. The results showed that the system could effectively deal with some safety problems such as out of control and collision caused by the vehicle faults and could ensure the safe operation of autonomous vehicle.
