Hybrid electric vehicle fault handling and arbitration method

The invention discloses a hybrid electric vehicle fault handling and arbitration method. The hybrid electric vehicle fault handling and arbitration method adopts the form of a bumpy driving mode and afault handling vector to express treatment measures when a single fault occurs, such as sensor fault, actuator fault, controller fault, CAN communication fault and all assembly fault states, the final bumpy driving mode and fault handling vector are determined by a newly invented hybrid electric vehicle fault handling and arbitration method, the application layer of a vehicle controller only needs to control the fault handling process according to the fault processing mode and fault processing vector after final arbitration, and the source of faults and the current number of the faults are not required to be considered. 本发明公开了种混合动力汽车故障处理及仲裁方法。本发明采用跛行模式和故障处理向量的形式表达传感器故障、执行器故障、控制器自身故障、CAN通讯故障、各总成故障状态等单个故障发生时的处理措施，并采用新发明的混合动力汽车故障处理及仲裁方法确定最终的跛行模式和故障处理向量，整车控制器应用层仅需根据最终仲裁后的故障处理模式和故障处理向量进行故障处理过程控制即可，无需考虑故障来源和当前故障数量。
