Embodiment Construction
[0029] As mentioned above, in the prior art, when a hybrid electric vehicle switches from pure electric mode to parallel mode, the engine will intervene to provide driving force. In the process of closing the clutch, there is a speed difference between the engine and the clutch when they are in contact with each other, which will make the engine and the clutch unable to match well, resulting in uneven power output when the car switches from pure electric mode to parallel mode, and the switching time The longer length makes the user feel a strong sense of shock and frustration, which seriously affects the driving experience.
[0030] The inventor of the present invention has found through research that the key to the above problem is that in the prior art, the engine is started at the idle speed, and then the engine is actively synchronized to adjust the speed from the idle speed to the target speed, which takes a long time, and when the clutch is closed afterwards The problem ...
