The invention relates to a hybrid vehicle engine start-stop dynamic control method. The invention belongs to the technical field of engine control methods. The engine starting process dynamic control method comprises the following steps that 11, a vehicle control unit sends an engine starting request to an engine; 12, the vehicle control unit sends a torque control command and a request torque initial value to the motor controller; 13, the ISG motor drags up the engine according to the torque request value; 14, the vehicle control unit optimizes the torque request value of the ISG motor; 15, whether the actual rotating speed of the engine is larger than the target idle speed of the engine is judged, if yes, the step 16 is executed, and if not, the step 13 is executed again; 16, the vehicle control unit sends an oil injection allowing instruction to the engine; and 17, the engine injects oil, and the feedback state of the engine is operation. The engine can be stopped working in a pure electric mode, the engine can be quickly started in a series or parallel mode, and the dynamic property is effectively improved.
本发明涉及一种混合动力车辆发动机启停动态控制方法。属于发动机控制方法技术领域。发动机启动过程动态控制包括以下步骤:步骤11整车控制器向发动机发送发动机的启动请求;步骤12整车控制器向电机控制器发送扭矩控制命令及请求扭矩初始值;步骤13 ISG电机跟随扭矩请求值拖起发动机;步骤14整车控制器优化ISG电机的扭矩请求值;步骤15判断发动机实际转速是否大于发动机目标怠速,如果结果为是,则进入步骤16,如果结果为否,则返回步骤13;步骤16整车控制器向发动机发送允许喷油指令;步骤17发动机喷油,发动机反馈状态为运行。本发明可以在纯电模式时停止发动机工作,在串联或者并联模式时快速启动发动机,有效提升动力性。
