It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0027] Figure 1 is a flow chart of an optional vehicle oil pump control method according to an embodiment of the present invention, such as Figure 1 As shown, the method comprises the following steps:

[0028] Step S102, determines the engine speed, the oil pressure of the fuel tank, the closed-loop control parameters of the vehicle oil pump and the first correction value of the oil pumping amount, the closed-loop control parameters are used to characterize the integral parameters or differential parameters of the closed-loop control of the oil pumping amount, and the first correction value is used to characterize the result obtained by correcting the oil pumping amount through closed-loop control.

[0029] The above-mentioned vehicle refers to a vehicle that can be driven by fuel, including but not limited to: a gasoline-powered car, a gasoline-powered bus, a gasoline-powered truck, a hybrid car, a hybrid bus or a hybrid truck, etc. The above-mentioned vehicle at least includes an engine, a fuel pump and a fuel tank, and the above-mentioned vehicle can correct the pumping amount of the vehicle fuel pump through closed-loop control.

[0030] The above-mentioned closed-loop control refers to a control method that affects and controls input through output. The input value can be controlled by the target output value and the actual output value. In the present application, the oil pumping amount of the oil pump can be controlled by the actual oil pressure of the vehicle engine and the target oil pressure of the vehicle engine. Among them, the above-mentioned closed-loop control can be: integral control (Integral Control), proportional-integral control (Proportional-Integral Control, PI Control) or proportional-integral-derivative control (Proportional-Integral-Derivative Control, referred to as PID control, etc.

[0031] The above-mentioned oil pumping amount refers to the oil pumping amount of the vehicle's oil pump. The vehicle uses the oil pump to pump the fuel in the vehicle's fuel tank into the vehicle's engine to drive the vehicle.

[0032] The above-mentioned closed-loop control parameters refer to parameters for closed-loop control of the oil pumping amount of the vehicle oil pump, which may include the historical correction amount of the vehicle oil pump during the historical time period, and may also control the control speed and control amplitude of the closed-loop control. In this application, the closed-loop control parameters include but are not limited to: historical correction amount, integral coefficient, integral gain and calculation step size.

[0033] The first correction amount is a correction amount for correcting the oil pumping amount of the oil pump through closed-loop control. The vehicle corrects the oil pumping amount of the oil pump for the first time through closed-loop control to obtain the first correction amount.

[0034] In an optional embodiment, the engine speed of the vehicle is determined by a speed sensor, the oil pressure of the oil tank is determined by a pressure sensor provided inside the oil tank, and the closed-loop control parameters of the vehicle oil pump are set before the oil pumping amount of the vehicle oil pump is controlled: the historical correction amount, the integral coefficient, the integral gain and the calculation step length, and the first correction amount of the oil pumping amount is determined through the closed-loop control, the closed-loop control parameter is used to characterize the integral parameter or differential parameter of the closed-loop control of the oil pumping amount, and the first correction amount is used to characterize the result obtained by correcting the oil pumping amount through the closed-loop control. Exemplarily, when the closed-loop control method of the vehicle is proportional-integral-differential control, the engine speed of the vehicle is determined by a speed sensor, the oil pressure of the oil tank is determined by a pressure sensor provided inside the oil tank, the integral gain, differential gain and proportional gain of the proportional-integral-differential control are determined, and the first correction amount of the oil pumping amount of the vehicle oil pump is determined through the integral gain, differential gain and proportional gain of the proportional-integral-differential control.

[0035] In another optional embodiment, when the closed-loop control method of the vehicle is proportional-integral control, the engine speed of the vehicle is determined by a speed sensor, the oil pressure of the fuel tank is determined by a pressure sensor installed inside the fuel tank, the integral gain and proportional gain of the proportional-integral control are determined, and the first correction amount of the oil pumping amount of the vehicle's oil pump is determined by the integral gain and proportional gain of the proportional-integral control.

[0036] In the present application, the first correction amount of the vehicle oil pump's oil pumping volume is determined through closed-loop control, so that the first correction amount of the vehicle oil pump is obtained through closed-loop control before considering the vehicle oil pumping capacity, thereby improving the accuracy of correcting the vehicle oil pump's oil pumping volume and effectively improving the user experience.

[0037] Step S104, determining the oil pumping capacity of the oil pump based on the vehicle state, engine speed, oil pressure and closed-loop control parameters.

[0038] The above-mentioned vehicle status refers to whether the vehicle is in a powered-on state. The vehicle status includes a powered-on state and a powered-off state. Only when the vehicle is in a powered-on state can the vehicle fuel pump be controlled by the vehicle fuel pump control method set in the vehicle control system. When the vehicle is in a powered-off state, the vehicle fuel pump cannot be controlled by the vehicle fuel pump control method set in the vehicle control system.

[0039] The above-mentioned oil pumping capacity refers to the ability of the vehicle oil pump to pump fuel to the vehicle engine. Since the oil pumping capacity of the vehicle oil pump may deteriorate after the vehicle has been running for a period of time, it is necessary to correct the oil pumping amount of the vehicle oil pump. Before correcting the oil pumping amount of the vehicle oil pump, it is necessary to determine whether the vehicle oil pump meets the correction conditions of the oil pumping amount, that is, to determine the oil pumping capacity of the vehicle oil pump. At this time, the oil pump can be determined by the vehicle state, engine speed, oil pressure and closed-loop control parameters to determine whether the oil pump meets the preset oil pumping capacity. In this application, the oil pumping capacity of the oil pump is determined by the vehicle state, engine speed, oil pressure and closed-loop control parameters to determine whether the oil pumping capacity of the vehicle oil pump meets the preset oil pumping capacity. Among them, the above-mentioned preset oil pumping capacity can be: the vehicle state is the power-on state, and the engine speed is greater than or equal to the speed threshold, and the oil pressure is within the preset oil pressure range, and the integral gain is not abnormal.

[0040] The above-mentioned speed threshold refers to a pre-set speed threshold of the vehicle engine. When the speed of the vehicle engine is greater than or equal to the speed threshold, the vehicle engine can work normally. The above-mentioned speed threshold can be set according to the engine status. The above-mentioned speed threshold can also be set manually according to experience and needs. The above-mentioned speed threshold can also be set according to the actual application scenario.

[0041] The above-mentioned preset oil pressure range refers to the preset oil pressure range in the vehicle's fuel tank. When the oil pressure in the vehicle's fuel tank is within the preset oil pressure range, the oil pump can normally pump the fuel in the fuel tank to the engine. The above-mentioned preset oil pressure range can be set according to the fuel tank status. The above-mentioned preset oil pressure range can also be set manually according to experience and needs. The above-mentioned preset oil pressure range can also be set according to the actual application scenario.

[0042] The above-mentioned abnormality in the integral gain refers to that the difference between the integral gain of the vehicle's oil pumping volume and the low-pass filter value of the integral gain is too large. When the difference between the integral gain of the oil pumping volume and the low-pass filter value of the integral gain is too large, it may cause the obtained correction amount to be inaccurate, so that the oil pumping volume of the vehicle's oil pump cannot be accurately controlled, resulting in sudden acceleration or deceleration when correcting the oil pumping volume of the vehicle's oil pump.

[0043] In an optional embodiment, it is determined whether the vehicle is in a powered-on state, the engine speed is compared with the speed threshold, whether the oil pressure is within a preset oil pressure range, and whether the integral gain is abnormal. When the vehicle is in a powered-on state, and the engine speed is greater than or equal to the speed threshold, and the oil pressure is within the preset oil pressure range, and the integral gain is not abnormal, it is determined that the vehicle oil pump meets the preset oil pumping capacity; when the vehicle is in a powered-off state, or the engine speed is less than the speed threshold, or the oil pressure is outside the preset oil pressure range, or the integral gain is abnormal, it is determined that the vehicle oil pump does not meet the preset oil pumping capacity.

[0044] In the present application, before determining the correction amount of the vehicle's oil pump's oil pumping volume, the oil pump's oil pumping capacity is first determined through the vehicle state, engine speed, oil pressure and closed-loop control parameters to determine whether the vehicle's oil pump meets the preset oil pumping capacity. Before correcting the vehicle's oil pump's oil pumping volume, it is first determined whether the vehicle meets the preset oil pumping capacity, which effectively improves the safety and stability of the vehicle's oil pump control and enhances the user experience.

[0045] Step S106, determining a second correction value of the oil pumping amount based on the oil pumping capacity and the closed-loop control parameter, wherein the second correction value is used to characterize a result obtained by correcting the oil pumping amount based on the oil pumping capacity of the oil pump.

[0046] The second correction amount is a correction amount for correcting the oil pumping amount of the vehicle oil pump based on the degradation of the oil pumping capacity of the vehicle oil pump. In the present application, the oil pumping capacity of the vehicle oil pump can be accurately corrected by combining the first correction amount and the second correction amount.

[0047] In an optional embodiment, when it is determined that the oil pumping capacity of the vehicle oil pump does not meet the preset oil pumping capacity, the second correction amount of the oil pumping amount of the vehicle oil pump is determined to be zero, and when it is determined that the oil pumping capacity of the vehicle oil pump meets the preset oil pumping capacity, the second correction amount is determined using the closed-loop control parameter. The second correction amount is used to characterize the result obtained by correcting the oil pumping amount based on the oil pumping capacity of the oil pump.

[0048] In another optional embodiment, according to the function model between the oil pumping capacity of the vehicle oil pump, the closed-loop control parameter and the second correction amount, after the oil pumping capacity and the closed-loop control parameter of the vehicle oil pump are determined, the oil pumping capacity and the closed-loop control parameter of the vehicle oil pump are brought into the above function model, and the second correction amount is determined by the function model. The second correction amount is used to characterize the result obtained by correcting the oil pumping amount based on the oil pumping capacity of the oil pump.

[0049] In the present application, when the vehicle's oil pumping capacity does not meet the preset oil pumping capacity, the second correction amount is determined to be zero to prevent sudden acceleration or sudden deceleration. When the vehicle's oil pumping capacity meets the preset oil pumping capacity, the second correction amount is calculated and combined with the first correction amount to correct the vehicle's oil pumping amount, which effectively improves the safety of the vehicle's oil pump control and improves the user experience.

[0050] Step S108, correcting the pump oil volume based on the first correction amount and the second correction amount to obtain a corrected pump oil volume.

[0051] In an optional embodiment, the first correction amount and the second correction amount are added to obtain a final correction amount, and the oil pumping amount of the vehicle oil pump is corrected by the final correction amount to obtain a corrected oil pumping amount.

[0052] In another optional embodiment, the first correction amount and the second correction amount are averaged to obtain a final correction amount, and the oil pumping amount of the vehicle oil pump is corrected by the final correction amount to obtain a corrected oil pumping amount.

[0053] In the present application, the oil pumping amount of the vehicle oil pump is corrected by combining the first correction amount and the second correction amount, which effectively improves the accuracy of correcting the oil pumping amount of the vehicle oil pump and improves the user experience.

[0054] Step S110, controlling the vehicle oil pump based on the corrected pump oil amount.

[0055] Through the above steps, the engine speed, the oil pressure of the fuel tank, the closed-loop control parameters of the vehicle oil pump and the first correction amount of the oil pumping amount are determined; the oil pumping capacity is determined based on the vehicle state, the engine speed, the oil pressure and the closed-loop control parameters; the second correction amount of the oil pumping amount is determined based on the oil pumping capacity and the closed-loop control parameters; the oil pumping amount is corrected based on the first correction amount and the second correction amount to obtain the corrected oil pumping amount; the vehicle oil pump is controlled based on the corrected oil pumping amount. The present application determines the oil pumping capacity of the oil pump to determine whether the oil pumping capacity of the vehicle oil pump meets the standard, and determines the second correction amount of the oil pumping amount according to the closed-loop control parameters when the vehicle oil pumping capacity meets the standard, and accurately corrects the oil pumping amount in combination with the first correction amount of the closed-loop control, taking into account the changes in the oil pumping capacity of the vehicle oil pump, so that the present application can control the vehicle oil pump more comprehensively, thereby achieving the technical effect of improving the reliability of the vehicle, and further solving the technical problem of low accuracy in controlling the vehicle oil pump due to the complex situation during the vehicle driving process.

[0056] Optionally, a second correction amount for the oil pumping amount is determined based on the oil pumping capacity and the closed-loop control parameters, including: in response to the oil pumping capacity satisfying a preset oil pumping capacity, determining the second correction amount using the closed-loop control parameters; in response to the oil pumping capacity not satisfying the preset oil pumping capacity, determining the second correction amount to be zero.

[0057] In an optional embodiment, when the vehicle is in a powered-on state, and the engine speed is greater than or equal to the speed threshold, and the oil pressure is within the preset oil pressure range, and the integral gain is not abnormal, that is, when the oil pumping capacity of the vehicle oil pump is determined to be that the oil pump meets the preset oil pumping capacity, the integral gain and the calculation step are integrated within the current time period to determine the second correction amount within the current time period, or the calculation step is divided by the integral coefficient to obtain a first result, the first result is multiplied by the integral gain to obtain a second result, and the second result is added to the historical second correction amount to determine the second correction amount within the current time period; when the vehicle is in a powered-off state, or the engine speed is less than the speed threshold, or the oil pressure is outside the preset oil pressure range, or the integral gain is abnormal, that is, when the oil pumping capacity of the vehicle oil pump is determined to be that the oil pump does not meet the preset oil pumping capacity, the second correction amount is determined to be zero.

[0058] In the present application, when the vehicle's oil pumping capacity does not meet the preset oil pumping capacity, the second correction amount is determined to be zero to prevent sudden acceleration or deceleration. When the vehicle's oil pumping capacity meets the preset oil pumping capacity, the second correction amount is calculated and combined with the first correction amount to correct the vehicle's oil pumping amount, which effectively improves the safety of the vehicle's oil pump control and enhances the user experience.

[0059] Optionally, the closed-loop control parameters include an integral gain and a calculation step size, and determining the second correction amount using the closed-loop control parameters includes: integrating the integral gain and the calculation step size within the current time period to determine the second correction amount within the current time period.

[0060] In an optional embodiment, the second correction amount of the current time period is determined by integrating the integral gain and the calculation step length within the current time period, wherein the calculation formula of the second correction amount of the current time period is as follows:

[0061] ,

[0062] in, is the second correction value for the current time period, To calculate the step size, is the integral gain.

[0063] In the present application, the integral gain and the calculation step are integrated within the current time period to quickly determine the second correction value within the current time period, which effectively improves the speed of obtaining the second correction value, improves the speed of vehicle oil pump control, and improves the user experience.

[0064] Optionally, the closed-loop control parameters include historical correction amounts, integral coefficients, integral gains and calculation steps within a historical time period, and using the closed-loop control parameters to determine the second correction amount also includes: dividing the calculation step length by the integral coefficient to obtain a first result; multiplying the first result by the integral gain to obtain a second result; adding the second result to the historical second correction amount to determine the second correction amount within the current time period; wherein the length of the historical time period is equal to the length of the current time period.

[0065] In an optional embodiment, the calculation step size is divided by the integral coefficient to obtain a first result, and the first result is multiplied by the integral gain to obtain a second result, and the second result is added to the historical second correction amount to determine the second correction amount in the current time period, wherein the calculation formula of the second correction amount in the current time period is as follows:

[0066] ,

[0067] in, is the second correction value in the current time period, It is the second historical revision. is the integral gain, To calculate the step size, is the integration coefficient.

[0068] In the present application, the second correction amount can also be determined by using the closed-loop control parameters through the historical correction amount, integral coefficient, integral gain and calculation step within the historical time period, so that the second correction amount within the current time period can be quickly obtained through the historical correction amount, integral coefficient, integral gain and calculation step, which effectively improves the acquisition speed of the second correction amount, improves the speed of vehicle oil pump control, and improves the user experience.

[0069] Optionally, the closed-loop control parameters include an integral gain, and the oil pumping capacity is determined based on the vehicle state, engine speed, oil pressure and closed-loop control parameters, including: detecting whether the integral gain is abnormal and obtaining a detection result; in response to the vehicle state being a powered-on state, the engine speed being greater than or equal to a speed threshold, and the oil pressure being within a preset oil pressure range, and determining that the detection result is that the integral gain is normal, determining that the oil pumping capacity is that the oil pump meets the preset oil pumping capacity; in response to the vehicle state being a powered-off state, or the engine speed being less than the speed threshold, or the oil pressure being outside the preset oil pressure range, or determining that the detection result is that the integral gain is abnormal, determining that the oil pumping capacity is that the oil pump does not meet the preset oil pumping capacity.

[0070] In an optional embodiment, based on the historical integral gain, integral gain, low-pass filter coefficient and calculation step size, the low-pass filter value of the integral gain is determined, and the detection result is determined based on the integral gain and the low-pass filter value, wherein the detection result is that the integral gain is normal or the integral gain is abnormal. When the vehicle state is the power-on state, and the engine speed is greater than or equal to the speed threshold, and the oil pressure is within the preset oil pressure range, and the integral gain is not abnormal, it is determined that the vehicle oil pump meets the preset oil pumping capacity; when the vehicle state is the power-off state, or the engine speed is less than the speed threshold, or the oil pressure is outside the preset oil pressure range, or the integral gain is abnormal, it is determined that the vehicle oil pump does not meet the preset oil pumping capacity.

[0071] In the present application, the oil pump's pumping capacity is determined by the vehicle status, engine speed, oil pressure and closed-loop control parameters to determine whether the vehicle oil pump meets the preset oil pumping capacity. If the vehicle oil pump does not meet the preset oil pumping capacity, the oil pumping amount of the vehicle oil pump is corrected only by the first correction amount. If the vehicle oil pump meets the preset oil pumping capacity, the oil pumping amount of the vehicle oil pump is corrected in combination with the first correction amount and the second correction amount, which effectively improves the safety and stability of the vehicle oil pump control and enhances the user experience.

After obtaining the low-pass filter value, the difference between the integral gain and the low-pass filter value is obtained to obtain the integral gain deviation. When the absolute value of the integral gain deviation is greater than the preset difference threshold, the detection result is determined to be an abnormal integral gain, and when the absolute value of the integral gain deviation is less than or equal to the preset difference threshold, the detection result is determined to be normal integral gain.

[0074] In the present application, the low-pass filter value of the integral gain is determined based on the historical integral gain, integral gain, low-pass filter coefficient and calculation step size, and the detection result is determined based on the integral gain and the low-pass filter value, thereby avoiding the situation where the difference between the integral gain of the oil pumping amount and the low-pass filter value of the integral gain is too large, which may cause the obtained second correction amount to be inaccurate, so that the oil pumping amount of the vehicle oil pump cannot be accurately controlled, resulting in sudden acceleration or deceleration when the oil pumping amount of the vehicle oil pump is corrected in combination with the first correction amount and the second correction amount, effectively improving the safety of the vehicle oil pump control, improving the safety of the vehicle, and improving the user experience.

[0075] Optionally, based on the historical integral gain, integral gain, low-pass filter coefficient and calculation step, the low-pass filter value of the integral gain is determined, including: obtaining the difference between the integral gain and the historical integral gain to obtain the integral gain difference; obtaining the ratio of the calculation step to the low-pass filter coefficient to obtain the low-pass filter step; obtaining the product of the integral gain difference and the low-pass filter step to obtain the integral gain change; obtaining the sum of the integral gain change and the historical integral gain to obtain the low-pass filter value.

[0077]

[0078] in, is the low-pass filter value, is the historical integral gain, is the integral gain, To calculate the step size, is the low-pass filter coefficient.

[0079] In this application, the low-pass filter value of the integral gain is quickly calculated and determined through historical integral gain, integral gain, low-pass filter coefficient and calculation step size, which effectively improves the speed of determining the detection results, improves the speed of vehicle oil pump control, and improves the user experience.

When the absolute value of the integral gain deviation is greater than a preset difference threshold, the integral gain deviation is too large, and the detection result is determined to be an integral gain abnormality; when the absolute value of the integral gain deviation is less than or equal to the preset difference threshold, the integral gain deviation is small, and the detection result is determined to be a normal integral gain.

[0083] In the present application, the difference between the integral gain and the low-pass filter value is compared with a preset difference threshold to determine the detection result, which effectively improves the speed of determining the detection result, improves the speed of vehicle oil pump control, and improves the user experience.

[0085] The correction amount threshold value refers to the threshold value for correcting the oil pumping amount of the vehicle oil pump.

When the second correction amount is greater than the correction amount threshold value, the vehicle oil pump may be faulty and the vehicle oil pump needs to be repaired. Among them, the correction amount threshold value can be set according to the state of the vehicle oil pump, the correction amount threshold value can also be set manually according to experience and needs, and the correction amount threshold value can also be set according to the actual application scenario.

[0086] In an optional embodiment, when the second correction amount is less than or equal to the correction amount threshold, the first correction amount and the second correction amount can be added to obtain a final correction amount, and the oil pumping amount of the vehicle oil pump can be corrected by the final correction amount. When the second correction amount is greater than the correction amount threshold, the vehicle oil pump needs to be repaired.

[0087] In another optional embodiment, when the second correction amount is less than or equal to the correction amount threshold, the first correction amount and the second correction amount can be averaged to obtain a final correction amount, and the oil pumping amount of the vehicle oil pump can be corrected by the final correction amount. When the second correction amount is greater than the correction amount threshold, the vehicle oil pump needs to be repaired.

[0088] In the present application, by comparing the second correction amount with the correction amount threshold, it is possible to quickly determine whether the vehicle oil pump is faulty, thereby effectively improving the safety of the vehicle oil pump control and improving the user experience.
