摘要
针对单轴并联混合动力客车结合离合器的模式切换,设计了发动机已启动和未启动时模式切换的控制策略.对于发动机未启动的模式切换,考虑离合器滑磨功和驾驶员需求,提出了在挡启动发动机和空挡启动发动机的控制策略.在转矩恢复时利用电机对发动机转矩进行补偿,考虑驾驶员需求、电池状态和整车控制策略,制定电机补偿发动机转矩的策略.通过台架和实车试验验证了策略的可行性与优越性.
The control strategy of mode switch with engine started and not started was designed for the mode switch that needs engagement of clutch on single-shaft parallel hybrid electric vehicle （HEV）. The clutch friction work and driver＇s intention were taken into account to determine the control strategy of starting the engine in particular gear or in neutral gear when the engine did not started. The motor could compensate engine torque during torque recovery phase and the compensation strategy was developed according to driver＇s demand, battery status and vehicle control strategy. The feasibility and superiority of the strategy were verified by bench and vehicle tests.
