[0051] Embodiment 1

[0052] This embodiment provides an intelligent oil pump start-stop control method for an oil-cooled electric drive system. The method can be executed by an intelligent oil pump start-stop control device for an oil-cooled electric drive system in an embodiment of the present invention.

[0055] The initial oil pump pre-lubrication control only involves the first power-on condition of the motor controller. Lubrication needs to be established under normal low-voltage power supply conditions for the first power-on, and the cooling oil must fully reach the bearing and reducer end;

[0056] 11) Obtain the maximum allowable control current of the oil pump;

[0057] 12) Record the oil pump load current under different oil pump power supplies, different oil temperatures, and different oil pump speeds;

[0058] 13) According to the maximum allowable current of the oil pump, the corresponding speed limit value under different oil pump power supply and oil temperature is obtained;

[0059] 14) Test the NVH conditions of different oil pump speeds on the vehicle and obtain the NVH limit oil pump speed constant;

[0060] 15) The speed limit values ​​of step 13) and step 14) are combined to take the minimum, and a two-dimensional MAP of the speed limit values ​​of the oil pump under different oil pump power supplies and questions is obtained;

[0061] 16) Under different oil pump speeds, the time required for the bearings and reducer to be fully lubricated is obtained through experiments, thereby obtaining the initial oil pump speed MAP and operating time under different oil pump power supplies and oil temperatures.

[0062] Step 2: See Figure 2 , under the flow rate calibrated in step 1, the initial oil pump intelligent start and stop are controlled as follows:

[0063] 21) The electric drive system is powered on for the first time;

[0064] 22) Detect low voltage power supply;

[0065] 23) Determine whether the low voltage power supply is greater than the threshold value A; if the low voltage power supply is greater than the threshold value A, execute step 24); if the low voltage power supply is not greater than the threshold value A, execute step 212);

[0066] Among them, the small battery on a normal car is about 12-14V. If the voltage is too low, the oil pump will not work. The threshold A is determined based on the operating power and time of the oil pump and the capacity of the small battery.

[0067] 24) Turn on the oil pump and it can be controlled;

[0068] 25) Output the initial fuel supply pump speed control command,

[0069] Among them, the initial fuel supply pump speed control command is output, the current fuel volume is first obtained, so as to obtain the initial fuel supply calibration MAP, and finally the initial fuel supply pump speed control command is output. The initial fuel pump control speed is obtained through step one;

[0070] 26) Initial fuel supply timer;

[0071] 27) Determine whether the timer upper limit is reached, if so, execute step 28), if not, return to step 26);

[0072] 28) The timer count is cleared to 0;

[0073] 29) Determine whether the high voltage power supply is greater than a threshold value B; if the high voltage power supply is greater than the threshold value B, execute step 210); if the high voltage power supply is not greater than the threshold value B, execute step 212);

[0074] Among them, threshold B is the lowest voltage of the high-voltage battery.

[0075] 210) determining whether the electric drive system is in a driving state, if the electric drive system is in a driving state, executing step 211), if the electric drive system is not in a driving state, executing step 212);

[0076] 211) Output the oil pump speed according to the actual working condition of the electric drive system;

[0077] 212) The oil pump speed control command is cleared to 0;

[0078] 213) Turn off the oil pump control enable.

[0079] In summary, the present invention controls the start and stop of the oil pump according to the low-pressure and high-pressure conditions of the whole vehicle, and turns off the oil pump when there is no demand for oil pump control. At the same time, the pre-lubrication requirement ensures that the oil fully reaches the bearings and gears of the electric drive system, thereby avoiding damage to the bearings or reducers due to insufficient lubrication during the initial driver's high-throttle acceleration condition, taking into account the system efficiency, cruising range and NVH characteristics of the whole vehicle, and also largely avoiding the small battery feeding caused by the power consumption of the oil pump.
