The invention belongs to the technical field of hybrid vehicle type engine control, and discloses a control method of a diesel hybrid vehicle engine start-stop mode. Through the hard wire connection of the ECU and the HCU and the related shutdown process design, the shutdown function requirement of the hybrid engine is easily met, the reliability is high, and the response is rapid. Through CAN message reading of the CAN bus, the HCU can obtain feedback of shutdown information, and closed-loop control is realized. The method is suitable for popularization in development projects of hybrid vehicle type control systems.
本发明属于混动车型发动机控制技术领域,公开了一种柴油混动车辆发动机启停模式的控制方法。通过ECU与HCU的硬线连接及相关停机流程设计,较简易的实现了一种混动发动机停机功能需求,可靠性较高且响应迅速。通过CAN总线的CAN消息读取,HCU可以获取停机信息的反馈,实现了闭环控制。适宜在混动车型控制系统开发项目中推广。
