Match the engine of hybrid vehicle, the opposite engine for matching traditional vehicle, engine be not it is whole all into
Row work only works when needing engine to provide power and power generation, therefore engine has frequent start and stop
Process.The preprocessor (catalyst converter) of engine requires initiation temperature, generally requires preprocessor inlet temperature greater than 300
DEG C just there is relatively high transformation efficiency.For matching the engine of hybrid vehicle, when engine is shut down, if shut down
Overlong time, preprocessor temperature slippage is excessive, causes in engine start, since preprocessor temperature is low, conversion effect
Rate is low, so as to cause high problem is discharged.
Prior art is that hybrid vehicle determines when engine starts according to the power battery electricity of vehicle,
The power threshold of engine start is arranged in entire car controller, when power battery electricity starts engine lower than the threshold value.The strategy
The temperature that After-treatment technics can not be monitored, when may cause engine start, since preprocessor temperature is low, transfer efficiency
It is low, it is high so as to cause discharge.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
