With reference to Fig. 3, according to the control method bag of the electric oil pump in the motor vehicle driven by mixed power of each embodiment of invention Include:Fuel temperature measurement step S10 of the oil temperature of measurement variator;Determine whether the oil temperature of variator is no more than predetermined ginseng 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 Rate, reduction noise simultaneously contribute to improving the persistency of electric oil pump.
Setting ultra low temperature determines the predetermined reference temperature in step S20, in view of in variator during setting The change of the viscosity of oil acts on the impact in the formation in response to the oil pressure of electric oil pump operation.In each embodiment, can Reference temperature is set at least -10 °C or lower of scope.
