The invention discloses a hybrid electric vehicle engine dynamic coordination control method and device which are applied to a coaxial series-parallel hybrid electric vehicle, and the coaxial series-parallel hybrid electric vehicle comprises an engine, a clutch 1, a motor 1, a clutch 2 and a motor 2 which are connected in sequence. The method comprises the steps that when an engine has a starting request, the starting mode of the engine is obtained; and according to the starting mode of the engine and the working state of the clutch, a dynamic coordination control method corresponding to engine starting and intervention is determined. According to the conditions of the actual state, the mode, the starting mode and the like of the whole vehicle, the two control methods of starting and intervening dynamic coordination control of the series hybrid power engine and starting and intervening dynamic coordination control of the parallel hybrid power engine can be achieved, impact on the whole vehicle is reduced as much as possible in the engine starting and intervening process, and the starting efficiency of the whole vehicle is improved. The vehicle driving smoothness, the NVH performance and the driving comfort of a driver are improved.

    本发明公开了一种混合动力汽车发动机动态协调控制方法和装置,应用于同轴混联式混合动力汽车中,同轴混联式混合动力汽车包括:依次连接的发动机、离合器1、电机1、离合器2以及电机2。该方法包括:当发动机有起动请求时,获取发动机的起动方式;根据发动机的起动方式,以及离合器的工作状态,确定发动机起动及介入对应的动态协调控制方法。本发明可以根据整车实际状态、模式、起动方式等条件,实现串联式混合动力发动机起动及介入动态协调控制、并联式混合动力发动机起动及介入动态协调控制两种控制方法,实现在发动机起动及介入过程中,尽可能的减少对整车的冲击,提高车辆行驶平顺性、NVH性能以及驾驶员的驾驶舒适感。
