The ultra low temperature for examining the ultra low temperature of temperature determines step S20；Control electric oil pump in an open-loop manner until target revolution the
One opened loop control step S30；And with closed loop control electric oil pump tracking closed loop control step S40 of target revolution.
When under ultra low temperature state start electric oil pump operation when, be not unconditionally control in an open-loop manner it is electronic
Oil pump is until predetermined reference revolution, this is different from correlation technique.On the contrary, in an open-loop manner control electric oil pump until
By transmission control unit（TCU）The target revolution of offer, then, controls electric oil pump in a closed loop manner.Therefore, this eliminates
The excessive initial launch more than target revolution of electric oil pump, so as to increase fuel oil effect by preventing unnecessary energy expenditure
