[0002] The present application claims priority to and the benefit of the filing date of Chinese Patent Application No. CN202411153168.6, filed August 21, 2024, and is hereby incorporated by reference in its entirety. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of electronic oil pumps, and in particular to a control method and device for an electronic oil pump, a vehicle and a storage medium. BACKGROUND

[0004] In today's automotive field, vehicles with engines as power sources or range extenders still occupy the main market of the automotive industry. When the engine is working, the high-speed friction between the surfaces of the parts not only increases the internal power consumption of the engine, but also causes wear of the parts in the engine, affecting the normal operation of the engine. Therefore, it is necessary to ensure the lubrication between the moving parts during the operation of the engine, reduce the friction resistance, reduce the power loss, reduce the wear and prolong the service life of the engine.

[0005] Most of the current vehicle engines use mechanical oil pumps. The pump speed of the mechanical oil pump is strongly coupled with the engine speed, and the main oil passage pressure is only controlled by the engine speed, which cannot meet the needs of all operating conditions. The electronic oil pump realizes the decoupling of the oil pump speed control and the engine speed, and can control the speed of the electronic oil pump according to the different operating conditions of the engine. However, the control strategy in the related art is still relatively rough, which cannot guarantee the fine control requirements of the engine under various operating conditions, resulting in that there may still be wear between the parts of the engine during operation, affecting the service life of the engine.

[0066] In order to solve the technical problem that the prior art cannot guarantee the fine control requirement of the engine under various working conditions, and the wear between the parts of the engine during operation still exists, affecting the service life of the engine, the present disclosure provides a control method, device, vehicle and storage medium. In the present disclosure, after the engine of the vehicle is started, it is first detected whether the pressure detection device has a fault. If the pressure detection device does not have a fault, the target request speed corresponding to the electronic oil pump can be determined based on the real-time engine oil state parameters such as real-time engine oil temperature and real-time engine oil pressure, and the real-time working condition parameters of the engine such as real-time engine speed and real-time engine torque. Then, the oil pump speed of the electronic oil pump is controlled based on the target request speed, which can better guarantee the fine control requirement of the engine under various working conditions, better improve the lubrication performance, better avoid the wear between the parts in the engine, better reduce the power loss of the engine, prolong the service life of the engine, and also improve the fuel economy of the vehicle.

[0067] In order to facilitate the understanding of the embodiments of the present disclosure, the following will be further explained and described in specific embodiments with reference to the drawings, and the embodiments do not constitute a limitation on the embodiments of the present disclosure.

[0068] The present embodiment provides a control method, which can be applied to a vehicle. Referring to FIGS. 1 and 2, the method can include:

[0069] S110, after the engine of the vehicle is started, detecting whether the pressure detection device has a fault;

[0070] S120, in the case where the pressure detection device does not have a fault, determining a target request rotating speed of the electronic oil pump based on a real-time engine oil state parameter and a real-time engine operating condition parameter;

[0071] S130, controlling the oil pump rotating speed of the electronic oil pump based on the target request rotating speed.

[0072] In step S110, whether the engine is started can be determined by detecting whether the engine is in a running state. If it is detected that the state of the engine is in the running state, it indicates that the engine is completed to be started. After the engine is started, the controller of the vehicle can detect whether the pressure detection device has a fault. The pressure detection device may, for example, include a pressure sensor for detecting the oil pressure to obtain a real-time oil pressure. It should be noted that the real-time oil pressure can refer to the oil pressure of the main oil gallery.

[0073] In step S120, the real-time engine oil state parameter at least includes a real-time engine oil temperature and a real-time engine oil pressure, and can also include other parameters related to the oil state according to requirements, which are not limited. The real-time operating condition parameter at least includes a real-time engine rotating speed and a real-time engine torque, and can also include other parameters related to the engine operating condition according to requirements, which are not limited. It should be noted that the real-time engine torque can reflect the real-time load of the engine. Therefore, the real-time engine load can also be used instead of the real-time engine torque.

[0074] Wherein, after obtaining the real-time engine oil state parameter and the real-time operating condition parameter, the corresponding basic oil pressure can be determined based on the real-time operating condition parameter.

[0075] It should be noted that the higher the engine rotating speed and the greater the engine torque, the greater the oil pressure required by the main oil gallery. In view of this, the required oil pressure of the main oil gallery under different engine operating conditions (engine rotating speed, engine torque) can be determined through a large amount of bench calibration data, so as to obtain first configuration information. The above-mentioned first configuration information can be stored in the vehicle, and the first configuration information can include a one-to-one correspondence relationship between a plurality of operating condition parameters and a plurality of oil pressures. The above-mentioned first configuration information can be stored in the form of a table, or can be stored in other forms (such as a main oil gallery pressure model), which are not limited.

[0076] In some embodiments, the engine speed in the first configuration information can include 1000, 1250, 1500, 1750, 2000, 2250, 2500, etc., and the unit can be revolutions per minute (r / min); the engine torque in the first configuration information can include 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 178, etc., and the unit can be Newton-meter (N m). Of course, other kinds of engine speed or engine torque can also be set according to actual needs, which are not limited.

[0077] When the base engine oil pressure needs to be determined, the first configuration information can be obtained from the storage location of the first configuration information, and then the same working condition parameter as the real-time working condition parameter is queried from the first configuration information, and then the engine oil pressure corresponding to the above-mentioned working condition parameter is determined as the engine oil pressure corresponding to the real-time working condition parameter, and is recorded as the base engine oil pressure.

[0078] In addition, the embodiment can introduce the influence of the oil temperature on the oil pump speed of the electronic oil pump, and the viscosity of the oil changes with the change of the temperature. Under the same oil pump speed, the engine oil pressure of the main oil passage has a certain difference at different oil temperatures. Therefore, the influence coefficient B of each oil temperature on the engine oil pressure can be determined through calibration to obtain the second configuration information. That is, the second configuration information can include a one-to-one correspondence relationship between multiple oil temperatures and multiple adjustment coefficients.

[0079] After obtaining the base engine oil pressure, the corresponding target engine oil pressure can be determined based on the base engine oil pressure and the real-time oil temperature to meet the lubrication demand at different temperatures, which is more conducive to protecting the engine.

[0080] After obtaining the base engine oil pressure, the second configuration information can be obtained from the storage location of the second configuration information, and then the same oil temperature as the real-time oil temperature is queried from the second configuration information, and then the adjustment coefficient corresponding to the above-mentioned oil temperature is determined as the target adjustment coefficient corresponding to the real-time oil temperature. Finally, the target engine oil pressure is determined based on the above-mentioned target adjustment coefficient and the base engine oil pressure.

[0081] In some embodiments,

[0082] The second configuration information can be stored in the vehicle in the form of a configuration table.

[0083] Configuration table

[0084] In this embodiment, if the real-time oil temperature is 10℃, the target adjustment coefficient B4 can be determined based on the above-mentioned configuration table.

[0085] It should be noted that in order to ensure the lubricating effect of the electronic oil pump on the engine under any working condition of the engine, a lower limit value of the oil pump speed of the electronic oil pump can be set, and as long as the oil pump speed of the electronic oil pump is not lower than the lower limit value of the oil pump speed corresponding to the oil temperature under the condition that the engine has a speed, the lower limit value of the oil pump speed is better to achieve the effect of protecting the engine, while reducing the power loss of the engine. That is, the vehicle in this embodiment can be configured with a lower limit configuration information of the oil pump speed in advance, and the lower limit configuration information of the oil pump speed can include a one-to-one correspondence between a plurality of oil temperatures and a plurality of lower limit values of the oil pump speed.

[0086] In this embodiment, when determining the target oil pressure based on the target adjustment coefficient and the basic oil pressure, the oil pump speed lower limit configuration information can be obtained from the storage location of the oil pump speed lower limit configuration information, and then the oil temperature corresponding to the target oil pump speed lower limit value corresponding to the real-time oil temperature can be found in the oil pump speed lower limit configuration information. Then, the lower limit value of the oil pump speed corresponding to the oil temperature obtained by querying is determined as the target oil pump speed lower limit value corresponding to the real-time oil temperature. Then, the product of the target adjustment coefficient and the basic oil pressure is compared with the target oil pump speed lower limit value, and the larger one of the two is determined as the target oil pressure.

[0087] Wherein, after obtaining the target oil pressure, the target request speed corresponding to the electronic oil pump can be determined based on the target oil pressure and the real-time engine speed. It should be noted that the target oil pressure can include 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600 and other kinds of oil pressure, and the unit can be bar. bar is the pressure unit in the international unit system, which is equal to 100,000 pascal (Pa) or 100 kPa. Of course, other kinds of target oil pressure can also be set according to actual needs, which is not limited

[0088] It should be noted that since the working state of PCJ (piston cooling oil injector) has a great influence on the oil pressure of the main oil passage, resulting in a great difference in the target request speed of the electronic oil pump, the different configuration information can be obtained based on the working state of PCJ when determining the target request speed.

[0089] Wherein, when determining the target request speed, the working state of PCJ can be detected first. Then, the corresponding target configuration information is determined based on the working state of PCJ. The target configuration information includes a one-to-one correspondence between a plurality of oil pressures, a plurality of engine speeds and a plurality of request speeds under the corresponding working state.

[0090] For example, if the working state of the PCJ is the open state, the first state configuration information corresponding to the open state can be determined as the target configuration information. The first state configuration information can include a one-to-one correspondence relationship among a plurality of oil pressures, a plurality of engine speeds and a plurality of request speeds in the open state. That is, the first state configuration information can include corresponding request speeds under different oil pressures and different engine speeds in the open state, and each group of oil pressure and engine speed corresponds to a unique request speed. If the working state of the PCJ is the closed state, the second state configuration information corresponding to the closed state can be determined as the target configuration information. The second state configuration information can include a one-to-one correspondence relationship among a plurality of oil pressures, a plurality of engine speeds and a plurality of request speeds in the closed state. That is, the second state configuration information can include corresponding request speeds under different oil pressures and different engine speeds in the closed state, and each group of oil pressure and engine speed corresponds to a unique request speed.

[0091] After the target configuration information is determined, the target request speed can be determined based on the target configuration information, the real-time engine speed and the target oil pressure. Among them, the request speed corresponding to the real-time engine speed and the target oil pressure in the target configuration information can be determined as the corresponding target request speed.

[0092] It should be noted that in addition to determining the target request speed in the above manner, the target request speed can also be determined in other manners, which are not limited.

[0093] In step S130, after the target request speed is determined, the oil pump speed of the electronic oil pump can be controlled based on the target request speed. For example, the target request speed can be sent to the electronic oil pump by the controller through the CAN line, and the electronic oil pump can respond to the speed control demand of the controller.

[0094] Among them, after the engine is started and it is determined that the pressure detection device is not faulty, the electronic oil pump can be controlled to operate at the target request speed without PID control, that is, without closed-loop control of the oil pump speed of the electronic oil pump based on the target oil pressure and the real-time oil pressure. After the first set time is reached, PID control of the oil pump speed can be started, that is, the oil pump speed of the electronic oil pump is controlled based on the target request speed and the difference between the target oil pressure and the real-time oil pressure. In this case, the target request speed can be combined, and the actual speed of the electronic oil pump can be adjusted according to the deviation between the target oil pressure and the actual oil pressure by using the PID control method, so as to ensure the consistency of the actual oil pressure and the target oil pressure, and realize closed-loop control.

[0095] In the embodiment, the operation of the electronic oil pump can be controlled under the actual use conditions of the engine, and the precise control of the oil pump speed of the electronic oil pump is realized. The controller controls the oil pump speed of the electronic oil pump according to various engine conditions and oil state parameters, decouples the oil pump speed from the engine speed, and controls the oil pump speed of the electronic oil pump according to the engine speed, torque, oil pressure of the main oil passage, oil temperature and other conditions, thereby having higher controllability and precision. The embodiment enables the engine to be fully lubricated while reducing the power loss of the engine and improving the fuel economy of the vehicle.

[0096] In addition, in the embodiment, after the engine is started, if it is detected that the pressure detection device (for example, the oil pressure sensor) has a fault, the real-time oil pressure of the main oil passage cannot be fed back at this time. In order to meet the engine lubrication under the current state, the oil pump speed of the electronic oil pump can be determined based on the engine speed and the engine torque and other parameters, and this process can no longer require closed-loop control. Moreover, the embodiment also provides an oil pump speed control strategy of the electronic oil pump under abnormal conditions. For example, when the real-time oil temperature is less than a temperature threshold (which can be set according to actual needs, and the specific value is not limited), the oil pump speed of the electronic oil pump can be determined based on the engine speed and the engine torque, and this process can also no longer require closed-loop control.

[0097] That is, in the case of a fault in the pressure detection device, the oil pump speed of the electronic oil pump can be controlled based on the real-time working condition parameters and the real-time oil temperature.

[0098] In the case where the real-time oil temperature is greater than or equal to the temperature threshold, the fifth configuration information can be obtained from the storage location of the fifth configuration information, and then the same working condition parameters as the real-time working condition parameters (for example, the real-time engine speed and the real-time engine torque) can be searched from the fifth configuration information. Then, the greater value between the requested speed corresponding to the searched working condition parameters and the lower limit value of the target oil pump speed corresponding to the real-time oil temperature is determined as the target requested speed. The fifth configuration information includes a one-to-one correspondence between a plurality of working condition parameters and a plurality of requested speeds, which can be calibrated in advance. After obtaining the target requested speed, the electronic oil pump can be controlled to operate at the target requested speed.

[0099] In the case where the real-time oil temperature is less than the temperature threshold, the requested speed corresponding to the real-time working condition parameters in the fifth configuration information can be determined as the first requested speed, and the requested speed corresponding to the real-time working condition parameters in the sixth configuration information can be determined as the second requested speed. The fifth configuration information includes a one-to-one correspondence between a plurality of working condition parameters and a plurality of requested speeds, and the sixth configuration information includes a one-to-one correspondence between a plurality of working condition parameters and a plurality of requested speeds. The fifth configuration information and the sixth configuration information can be stored in the vehicle after being calibrated in advance.

[0100] Wherein, after obtaining the first request speed and the second request speed, the target request speed can be determined based on the larger request speed between the first request speed and the second request speed. It should be noted that the target request speed can also be related to the target oil pump speed lower limit value, that is, the larger value between the above-mentioned larger request speed and the target oil pump speed lower limit value can be determined as the target request speed. Then, the electronic oil pump is controlled to operate at the target request speed.

[0101] In addition, in this embodiment, before the engine starts, if the pre-pressurization request is detected and the engine start request is not detected, the pre-pressurization mode is started to control the electronic oil pump to operate at the set speed in response to the pre-pressurization request. The pre-pressurization request is used to start the pre-pressurization mode. In the pre-pressurization mode, if it is determined that the electronic oil pump operates at the set speed for a second set time length, and / or if it is determined that the real-time oil pressure reaches the set oil pressure, the electronic oil pump is controlled to stop operating to complete the pre-pressurization of the lubrication system and end the pre-pressurization mode.

[0102] Wherein, the set speed, the second set time length and the set pressure can be set according to actual needs, and their specific values are not limited. It should be noted that the information pre-set in the vehicle in this embodiment can be modified according to needs later to better meet the different needs of users.

[0103] Wherein, before the engine starts, if both the pre-pressurization request and the engine start request are detected, that is, the pre-pressurization request and the engine start request are detected, the engine start request is given priority and the engine is started in response to the engine start request.

[0104] In some embodiments,

[0105] After the power gear of the vehicle changes from Key off to Key on and the state of the engine is still stationary, the pre-pressurization request can be detected, and then the pre-pressurization of the lubrication system is performed in response to the pre-pressurization request. When the start success flag is set, the engine start request can be detected, and then the engine can be started to switch the state of the engine to the running state. After the engine is in the running state, that is, after the engine is started, it can be detected whether the pressure detection device has a fault, and then the subsequent control of the oil pump speed of the electronic oil pump is performed.

[0106] This embodiment selects the corresponding control strategy to control the oil pump speed of the electronic oil pump according to the current vehicle operating condition through the controller, so that the vehicle can meet the lubrication demand of the engine and reduce the power loss of the engine and improve the fuel economy of the vehicle through the accurate control of the oil pump speed under different conditions.

[0107] In some embodiments,

[0108] After the vehicle power supply is powered on, the controller can monitor the fault state of the pressure detection device. If it is monitored that the pressure detection device is not faulty, at this time the engine has not started, the controller can control the electronic oil pump to run at a fixed speed for a period of time to pre-pressurize the main oil passage, so as to eliminate the situation of no lubrication or insufficient lubrication in a short time after the engine starts. During the engine starting process and after the engine starts, the lower limit value of the oil pump speed of the electronic oil pump can be limited, and the limitation is only in the engine with speed, and other working conditions are not enabled. Then, the target request speed of the electronic oil pump is calculated based on the real-time engine speed, real-time engine torque, real-time engine oil pressure, real-time engine oil temperature and other parameters. In addition, when it is detected that the pressure detection device for detecting the engine oil pressure is faulty, other corresponding control strategies can be used to control the oil pump speed of the electronic oil pump to ensure that the engine lubrication state is good.

[0109] In the embodiment, the control functions of the engine and the electronic oil pump can be realized by an EMS (Engine Management System, engine management system), which includes a controller, an electronic oil pump, an oil temperature sensor, an oil pressure sensor, an engine speed sensor, an intake pressure sensor and the like. After the vehicle is powered on, the oil pressure sensor, the oil temperature sensor and the engine speed sensor can be connected to the controller through a hard wire. The engine management system sends the target request speed to the CAN bus. The electronic oil pump sends communication faults, controller pre-drive faults, controller temperature sensor faults, motor stall faults, position sensor faults and the like to the CAN bus.

[0110] The controller receives the CAN bus signals and hard wire signals above, and comprehensively judges the demand for the oil pump speed in the current driving condition in combination with the current running condition of the controller, to perform real-time control and adjustment. At the same time, the signals are sent to the CAN bus.

[0111] The embodiment can better guarantee that the engine realizes relatively fine control requirements in various conditions, better improve the lubrication performance, better avoid the wear between parts in the engine, better reduce the power loss of the engine, prolong the service life of the engine, and also improve the fuel economy of the vehicle.
