Optionally, the control unit may also be connected to the low-pressure oil pump and the high-pressure oil pump for controlling the operating states of the low-pressure oil pump and the high-pressure oil pump.
Fig. 2 is a flow chart of an alternative oil vapor control method of the present application, as shown in fig. 2. Disclosed herein in one aspect is a control method of oil vapor, including:
s201, acquiring a pressure value set of an oil suction port of the high-pressure oil pump by using a pressure sensor.
The technical solution will be explained below by taking a control unit of the vehicle as an execution subject, and in step S201, the control unit may acquire a set of pressure values of the oil suction port of the high-pressure oil pump through the pressure sensor for preparing for subsequent control of the vehicle.
In an alternative embodiment, step S201 includes:
the control unit acquires a pressure value corresponding to each time point in a plurality of preset time points based on the pressure sensor, wherein each time point is a time point corresponding to each oil absorption of the high-pressure oil pump; and the control unit obtains the pressure value set according to the pressure value corresponding to each time point. For example, as shown in fig. 3, fig. 3 is a diagram illustrating pressure value sets in an alternative embodiment of the present application. The pressure values corresponding to 6 moments acquired by the pressure sensor, namely the pressure value P1 at the time point of t1, the pressure value P2 at the time point of t2, the pressure value P3 at the time point of t3, the pressure value P4 at the time point of t4, the pressure value P5 at the time point of t5, and the pressure value P6 at the time point of t6 are set to be { P1, P2, P3, P4, P5, P6}, so that the identification result, namely whether oil vapor exists in the pipeline or not, can be obtained by analyzing and processing the pressure value set subsequently.
In an optional embodiment, the low-pressure oil pump is connected in communication with the pressure sensor, the control system for reducing oil vapor further includes a processing unit, the low-pressure oil pump is connected with the processing unit and constitutes a low-pressure oil pump control system, the processing unit is connected in communication with the pressure sensor, and the control unit acquires a signal of the pressure sensor by being connected with the processing unit, wherein the signal of the pressure sensor contains the time point and the corresponding pressure value information. The embodiment can be used in the scene of a control system with a low-pressure oil pump in a vehicle, so that the oil vapor in the pipeline can be controlled under the condition of reducing the change of the circuit connection of the vehicle.
S202, the control unit determines an identification result based on the pressure value set.
In this embodiment, the identification result includes two cases, one is that the oil vapor is present in the pipe and the other is that the oil vapor is not present in the pipe.
In an alternative embodiment, step S202 includes:
the control unit determines a pressure value set to be judged from the pressure value set, wherein the pressure value in the pressure value set to be judged is less than or equal to a preset pressure value; if the number of the pressure values in the set of pressure values to be judged is larger than or equal to a first preset number, the control unit determines that the identification result is that oil vapor exists, and the pressure values of the first preset number are the pressure values corresponding to the continuous time points. That is, for example, when the first preset number is 3, the preset pressure value is P0, and when the pressure values corresponding to successive time points in { P1, P2, P3, P4, P5, P6}, such as P4, P5, P6, are all less than or equal to P0, the control unit determines that oil vapor exists in the pipeline from the time point t4, at this time, the oil vapor suppression system may be adopted, and since there is no oil vapor in the time period t1-t4, measures for suppressing oil vapor are not required for the vehicle, the low-pressure oil pump of the vehicle can still operate at a lower oil pressure, a lower pressure limit can be provided for oil pressure control of the low-pressure oil pump, minimum energy consumption control of the low-pressure oil pump is realized, and the fuel consumption level is reduced.
Of course, since the operation of the high-pressure oil pump is periodic and intermittent, the pressure value detected by the actual pressure sensor at a continuous time point is continuously fluctuated, and when oil vapor exists in the oil suction port or the pipeline of the high-pressure oil pump, the oil pressure fluctuation at the oil suction port of the high-pressure oil pump is reduced, the preset pressure value P0 can be obtained from historical experimental data, and in order to make the judgment result more accurate, the first preset number may be set to 10 or 20.

In an alternative embodiment, the pressure value set P ═ { P1, P2, P3, P4, P5, P6} may determine 5 pressure error values, and the pressure values at successively adjacent time points are subtracted and the absolute value is taken, so as to obtain corresponding pressure error values, i.e., G1 ═ P1-P2|, G2 ═ P2-P3|, G3 ═ P3-P4|, G4 ═ P4-P5|, G5 ═ P5-P6|, alternatively, the larger of the two adjacent pressure values may be set as a subtracted number, and the other is set as a subtracted number, so as to directly obtain the corresponding pressure error value.

That is, the pressure value error value set G ═ { G1, G2, G3, G4, G5}

For example, when the pressure error values obtained at 4 consecutive time points, i.e., t3-t6, are G3, G4, and G5, and G3, G4, and G5 are all less than or equal to the preset pressure error value G0, a set of the pressure error values determined by the belt is formed by G3, G4, and G5, and optionally, the pressure error value G0 is 0 to 5 kpa.
S304, if the number of the pressure error values in the pressure error value set to be judged is more than or equal to a second preset number, the control unit determines that the identification result is that oil vapor exists, and the pressure error values of the second preset number are the pressure error values corresponding to the continuous time points.
That is, following the example of step S303, when the second preset number is 3, and the number in the pressure error value set is equal to 3, the control unit determines that oil vapor exists in the current pipeline.
S203, if the oil vapor exists in the identification result, the control unit starts a gasification inhibition control system.

In another alternative embodiment, the control unit initiates a suppressed gasification control system comprising: and the control unit resets the pressure value of the low-pressure oil pump, wherein the pressure value of the low-pressure oil pump is greater than the current pressure value of the low-pressure oil pump.
In an alternative embodiment, the pressure value of the low-pressure oil pump is increased by the control unit, and a low-pressure oil pump pressure value is set directly according to historical experience, wherein the set low-pressure oil pump pressure value is larger than the current low-pressure oil pump pressure value.
In another alternative embodiment, the control unit sets a preset increment value x, if the current low-pressure oil pump pressure value is n, the pressure value of the low-pressure oil pump is adjusted for the first time to be n + x, and repeats the above steps S201 to S202, if the obtained identification result still has oil vapor, the control unit performs a second adjustment, and the pressure value of the low-pressure oil pump is adjusted for the second time to be n +2x, that is, the pressure value after each adjustment of the low-pressure oil pump pressure value is the last low-pressure oil pump pressure value plus the preset increment value, until the detected identification result is that no oil vapor exists, the control unit completes the adjustment of the pressure value of the low-pressure oil pump.
In another alternative embodiment, when there is a deviation between the set pressure value of the low pressure oil pump and the pressure value of the output of the actual low pressure oil pump, a correction coefficient is obtained from the history data, and the set pressure value of the low pressure oil pump is equal to the pressure value of the target low pressure oil pump multiplied by the correction coefficient.
