Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a control method, device, equipment, and storage medium for a vehicle oil pump. Background Technology

[0002] With the widespread use of automobiles, people are paying more and more attention to their performance, and the engine, as an important component of automobiles, is also constantly improving its performance.

[0003] The temperature of engine oil directly affects the engine's operating condition. Too low a temperature will increase the resistance of moving parts, while too high a temperature will cause it to lose its lubricating effect.

[0004] However, the methods for controlling engine oil temperature in related technologies are not precise enough to achieve optimal engine performance. Summary of the Invention

[0005] This invention provides a method, device, equipment, and storage medium for controlling a vehicle oil pump, in order to solve the problem that the method for controlling engine oil temperature is not precise enough and cannot bring out the engine's optimal performance.

[0006] According to one aspect of the present invention, a method for controlling a vehicle oil pump is provided, the method comprising:

[0007] In response to a cold start control command, the engine operating status of the target vehicle is obtained;

[0008] When the operating state is "operation has started", the actual oil temperature of the target vehicle is obtained;

[0009] Based on the actual oil temperature, the temperature control stage of the target vehicle is determined, and the oil pump of the target vehicle is controlled to operate according to the temperature control stage.

[0010] According to another aspect of the present invention, a control device for a vehicle oil pump is provided, the device comprising:

[0011] The engine start module is used to obtain the operating status of the engine of the target vehicle in response to cold start control commands.

[0012] The oil temperature acquisition module is used to acquire the actual oil temperature of the target vehicle when the operating state is "started".

[0013] The oil pump operation control module is used to determine the temperature control stage of the target vehicle based on the actual oil temperature, and control the oil pump of the target vehicle to operate according to the temperature control stage.

[0014] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the vehicle oil pump control method according to any embodiment of the present invention.

[0018] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the vehicle oil pump control method according to any embodiment of the present invention.

[0019] The technical solution of this invention first obtains the operating status of the target vehicle's engine in response to a cold start control command. If the engine is already running, the actual oil temperature of the target vehicle is obtained, ensuring timely and accurate monitoring of the oil temperature while the engine is running. Then, based on the actual oil temperature, the temperature control stage of the target vehicle is determined, and the oil pump of the target vehicle is controlled to operate according to the temperature control stage. This allows the target vehicle to control the oil temperature based on the oil pump operation at different temperature control stages. This solves the problem of insufficient precision in engine oil temperature control methods. It achieves accurate and effective control of engine oil temperature without increasing or decreasing hardware costs, resulting in improved engine performance.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] It should be noted that the terms "first," "second," and "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0032] Example 1

[0033] Figure 1This is a flowchart illustrating a vehicle oil pump control method according to Embodiment 1 of the present invention. This embodiment is applicable to controlling the operation of a vehicle oil pump. The method can be executed by a vehicle oil pump control device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0034] S110: In response to the cold start control command, obtain the operating status of the engine of the target vehicle.

[0035] The cold start control command can be a command to control the engine ignition and start. Obtaining the engine operating status of the target vehicle can mean obtaining information on whether the engine has started running. It is understood that the engine operating status includes at least two states: started or not running. It is also understood that when the target vehicle experiences difficulty in cold starting due to internal or external factors such as temperature and the condition of internal components, and requires repeated ignition attempts, the number of times the engine operating status of the target vehicle is obtained can correspond to the number of repeated cold start control commands.

[0036] Specifically, in response to the cold start control command of the target vehicle, the operating status of the target vehicle's engine is obtained, indicating whether the engine has started running.

[0037] For example, the driver of the target vehicle triggers a cold start control command to start the vehicle, and the engine of the target vehicle has started running. At this time, in response to the cold start control command, the operating state of the target vehicle's engine, indicating that it has started running, can be obtained. For example, the driver of the target vehicle repeatedly triggers the cold start control command to start the vehicle, but due to the low temperature, the engine of the target vehicle does not start running until the third ignition attempt. At this time, in response to three cold start control commands, the operating states of the target vehicle's engine can be obtained three times, which can be: not running, not running, and running.

[0038] S120. When the operating status is "already started", obtain the actual oil temperature of the target vehicle.

[0039] The actual oil temperature of the target vehicle can be the real-time temperature of the engine oil in the target vehicle obtained from an oil temperature sensor.

[0040] Specifically, when the engine of the target vehicle is running, the real-time temperature of the engine oil in the target vehicle is obtained based on the target vehicle's oil temperature sensor.

[0041] S130. Determine the temperature control stage of the target vehicle based on the actual oil temperature, and control the oil pump of the target vehicle to operate according to the temperature control stage.

[0042] The temperature control stage can be a division of temperature range used to indicate the state of the engine oil temperature, such as a low-temperature control stage or a high-temperature control stage. Different temperature stages can correspond to different temperature limit ranges. The oil pump in the target vehicle can be the oil pump that controls the engine lubrication system, such as an oil pump.

[0043] Specifically, after determining the temperature control stage of the target vehicle based on the actual oil temperature, the oil pump of the target vehicle can be controlled according to the temperature control stage.

[0044] For example, based on an actual oil temperature of 105°C, the target vehicle is determined to be in a high-temperature control phase. At this time, the oil pump of the target vehicle can be controlled to operate at high speed according to the temperature control phase, so as to reduce the engine oil temperature of the target vehicle.

[0045] Optionally, the temperature control phase includes a cold start control phase, a warm-up control phase, a normal temperature control phase, and a high temperature control phase; the actual oil temperature increases sequentially for the cold start control phase, the warm-up control phase, the normal temperature control phase, and the high temperature control phase; the oil pump's continuous operating time and / or oil pump speed are higher for the temperature control phase with a higher actual oil temperature than for the temperature control phase with a lower actual oil temperature.

[0046] The actual oil temperature increases sequentially between the cold start control stage, the warm-up control stage, the normal temperature control stage, and the high temperature control stage. This can be understood as follows: the actual oil temperature in the cold start control stage is lower than that in the warm-up control stage, the actual oil temperature in the warm-up control stage is lower than that in the normal temperature control stage, and the actual oil temperature in the normal temperature control stage is lower than that in the high temperature control stage.

[0047] For example, based on an actual oil temperature of 15°C, it can be determined that the target vehicle is in the cold start control stage of temperature control. At this time, the control strategy for the cold start control stage can be used to control the target vehicle's oil pump to operate intermittently at a low speed, allowing the engine oil to heat up quickly. When the actual oil temperature is 105°C, it can be determined that the target vehicle is in the high-temperature control stage of temperature control. At this time, the control strategy for the high-temperature control stage can be used to control the target vehicle's oil pump to operate continuously for a long time at a high speed, increasing the oil flow through the oil heat exchanger and thus allowing the engine oil temperature to drop rapidly.

[0048] In embodiments of the present invention, the actual oil temperature of an engine already in operation is acquired, a temperature control stage is determined, and the oil pump of the target vehicle is controlled according to the temperature control stage. This allows the target vehicle to control the oil temperature based on the oil pump operation at different temperature control stages. This achieves accurate and effective control of engine oil temperature without increasing or decreasing hardware costs, resulting in improved engine performance.

[0049] Example 2

[0050] Figure 2 This is a flowchart illustrating a vehicle oil pump control method according to Embodiment 2 of the present invention. This embodiment, based on the above embodiments, specifically describes the oil pump control method during the cold start control phase. For detailed implementation methods, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 2 As shown, the method includes:

[0051] S210: In response to the cold start control command, obtain the operating status of the engine of the target vehicle.

[0052] S220. When the operating status is "already started", obtain the actual oil temperature of the target vehicle.

[0053] S230, Determine the temperature control stage of the target vehicle based on the actual engine oil temperature.

[0054] S240. When the temperature control stage is the cold start control stage, the oil pump of the target vehicle is in a stopped state.

[0055] For example, when the engine of a target vehicle has just started, the temperature control stage of the target vehicle can be determined to be the cold start control stage based on the actual oil temperature of the target vehicle. In this case, the actual oil temperature of the target vehicle is generally in a low range, such as 15°C. At this time, the temperature control stage of the target vehicle can be determined as the cold start control stage, and the oil pump of the target vehicle can be controlled to be stopped.

[0056] S250: If the first stop time of the oil pump in the stop state reaches the preset first time threshold, control the oil pump to run at the first speed.

[0057] In this embodiment, the first stop duration can be a fixed duration during which the oil pump is in a stopped state when the temperature control phase is a cold start control phase. The preset first duration threshold can be a time threshold pre-set according to actual conditions to indicate when the first stop duration reaches its maximum value. The first speed can be the oil pump speed of the target vehicle when the temperature control phase is a cold start control phase. It can be understood that since the cold start control phase is a temperature control phase where the actual oil temperature is low, operating at the first speed can be the lower speed state of the target vehicle's oil pump.

[0058] For example, if the duration of the oil pump being stopped reaches a preset first duration threshold, the oil pump can be controlled to operate at a lower speed with a first rotational speed.

[0059] S260: Determine whether the first operating time of the oil pump has reached the preset second time threshold and whether the temperature control stage is still the cold start control stage. If so, return to execute the operation of S240. Otherwise, end the control of the cold start control stage.

[0060] Among them, the first duration threshold is greater than the second duration threshold.

[0061] In this embodiment of the invention, the control to end the cold start control phase includes: when the duration of the cold start control phase is greater than a preset first control duration, ending the control of the cold start control phase and generating an abnormal prompt message; or, when it is determined that the target vehicle is in another temperature control phase, executing control logic corresponding to the other temperature control phase.

[0062] In this embodiment, the first operating duration can be a fixed duration during which the oil pump is in operation when the temperature control phase is a cold start control phase. The preset second duration threshold can be a time threshold pre-set according to actual conditions to indicate when the first operating duration reaches its maximum value. It is understood that during the cold start control phase, because it is necessary to rapidly increase the oil temperature, and the oil pump being in a stopped state helps to increase the oil temperature, the first duration threshold (indicating the first stop duration) is greater than the second duration threshold (indicating the first operating duration). For example, the first duration threshold can be more than 10 times the second duration threshold.

[0063] Specifically, if the first operating time of the oil pump is detected to reach the preset second time threshold, and the temperature control stage is still the cold start control stage, it can be determined that the actual oil temperature of the target vehicle is still in a low temperature state. At this time, the operation of controlling the oil pump of the target vehicle to be stopped can be returned.

[0064] For example, based on the foregoing embodiments, when the target vehicle's oil pump operates at a first speed, and the operating time (first operating time) reaches a preset second time threshold, the control can return to stopping the target vehicle's oil pump. It is understood that if the oil pump is detected to have been stopped for another time reaching the preset first time threshold, the control can resume operation at the first speed. This operation / stop process can be repeated until the actual oil temperature of the target vehicle rises, at which point the temperature control phase enters the temperature rise control phase.

[0065] In embodiments of the present invention, the oil temperature is adjusted by controlling the stop and run durations of the oil pump in the target vehicle during the cold start control phase. That is, the target vehicle controls the oil temperature based on the oil pump operation adjustment strategy. Furthermore, through prolonged stoppage and short periods of operation, a stable adjustment of the oil temperature is achieved, and without increasing or decreasing hardware costs, the engine oil temperature is accurately and effectively controlled, resulting in a beneficial effect on improving engine performance.

[0066] Example 3

[0067] Figure 3 This is a flowchart illustrating a vehicle oil pump control method according to Embodiment 2 of the present invention. This embodiment, based on the above embodiments, specifically describes the oil pump control method during the temperature rise control stage. For detailed implementation methods, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 3 As shown, the method includes:

[0068] S310: In response to the cold start control command, obtain the operating status of the engine of the target vehicle.

[0069] S320. When the operating status is "already started", obtain the actual oil temperature of the target vehicle.

[0070] S330: Determine the temperature control stage of the target vehicle based on the actual engine oil temperature.

[0071] S340. When the temperature control stage is the temperature rise control stage, the oil pump of the target vehicle is in a stopped state.

[0072] When the engine oil temperature of the target vehicle reaches or exceeds the minimum temperature value of the preset temperature rise control stage, the corresponding temperature control stage for the target vehicle is determined to be the temperature rise control stage. For example, when the actual engine oil temperature is higher than the minimum temperature value of the preset temperature rise control stage, it can be determined that the temperature rise control stage has been reached. In this case, the oil pump of the target vehicle can be controlled to stop.

[0073] S350: When the second stop time of the oil pump being in a stop state reaches a preset third time threshold, the oil pump is controlled to run at a first speed.

[0074] In this embodiment, it can be understood that the second stop duration and the preset third duration threshold are similar to the first stop duration and the preset first duration threshold in the aforementioned embodiments, representing the fixed duration for which the oil pump is in a stop state when the temperature control stage is a temperature rise control stage, and the threshold used to indicate that the second stop duration has reached its maximum value. S330: If it is detected that the second operating duration of the oil pump has reached the preset fourth duration threshold and the temperature control stage is still a temperature rise control stage, return to execute S310, wherein the third duration threshold is greater than the fourth duration threshold.

[0075] The second operating duration and the preset fourth duration threshold can be similar to the first operating duration and the preset second duration threshold in the aforementioned embodiments, representing the fixed duration for which the oil pump is in operation when the temperature control phase is a temperature rise control phase, and the threshold used to indicate that the second operating duration has reached its maximum value. It is understood that in the temperature rise control phase, since it is still necessary to increase the oil temperature, and the oil pump being in a stopped state helps to increase the oil temperature, the third duration threshold (indicating the second stop duration) is greater than the fourth duration threshold (indicating the second operating duration). For example, the first duration threshold can be more than five times the second duration threshold.

[0076] For example, based on the foregoing embodiments, when the temperature control phase is detected as a temperature rise control phase, the oil pump of the target vehicle is controlled to be in a stopped state. If the duration of the oil pump being in a stopped state reaches a preset third time threshold, the oil pump can be controlled to operate at a lower speed (first speed). When the second operating time reaches a preset fourth time threshold, the oil pump of the target vehicle can be controlled to be stopped again. It is understood that if the duration of the oil pump being stopped is detected again, i.e., the second stop time again reaches the preset third time threshold, the oil pump can be controlled to operate at the first speed again. The above operating / stopping process can be repeated until the actual oil temperature of the target vehicle further increases, and the temperature control phase enters the normal temperature control phase.

[0077] S360: If the second operating time of the oil pump reaches the preset fourth time threshold and the temperature control stage is still the temperature rise control stage, return to the operation of S340; otherwise, end the control of the SHEN temperature rise control stage.

[0078] Among them, the third duration threshold is greater than the fourth duration threshold.

[0079] The technical solution of this invention controls the engine oil temperature during the temperature control phase by controlling the oil pump of the target vehicle to stop and start. Furthermore, the adjustment method is simple, achieved through prolonged periods of stoppage and short periods of operation, and it achieves stable adjustment of the engine oil temperature. Without increasing or decreasing hardware costs, it accurately and effectively controls the engine oil temperature, thus improving engine performance.

[0080] Example 4

[0081] Figure 4 This is a flowchart illustrating a vehicle oil pump control method according to Embodiment 4 of the present invention. This embodiment, based on the above embodiments, specifically describes the oil pump control method during the normal temperature control stage. For detailed implementation methods, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 4 As shown, the method includes:

[0082] S410: In response to a cold start control command, obtain the engine operating status of the target vehicle.

[0083] S420. When the operating status is "already started", obtain the actual oil temperature of the target vehicle.

[0084] S430: Determine the temperature control stage of the target vehicle based on the actual oil temperature.

[0085] S440. When the temperature control stage is the normal temperature control stage, the speed of the oil pump of the target vehicle is adjusted by the first enhancement coefficient so that the oil pump operates at the target speed.

[0086] The first enhancement coefficient is related to the actual oil temperature and the temperature difference between the actual oil temperature and the target oil temperature, while the target speed is related to the engine speed and engine load.

[0087] In this embodiment, the normal temperature control stage can be the temperature control stage determined based on the actual oil temperature when the target vehicle is driving normally on a normal road. The first enhancement coefficient can be an adjustment coefficient used to regulate the speed of the oil pump in the target vehicle. The target oil temperature can be the oil temperature most suitable for the engine to perform optimally when the temperature control stage is the normal temperature control stage. The first enhancement coefficient can be determined based on the temperature difference between the actual oil temperature and the target oil temperature. It is understood that the first enhancement coefficient can be positively correlated with the temperature difference between the actual oil temperature and the target oil temperature. The target speed can be the suitable speed of the oil pump determined based on the engine speed and engine load. The target speed can be a range of suitable speeds or a fixed value; this invention does not limit this. By adjusting the speed of the oil pump in the target vehicle with the first enhancement coefficient, the oil pump can be made to operate at the target speed, thereby controlling the oil temperature to reach the oil temperature most suitable for the engine to perform optimally.

[0088] For example, when the target vehicle is driving normally on a regular road, the temperature control stage determined by the actual oil temperature is the normal temperature control stage. The appropriate oil pump speed (target speed) is determined based on the engine speed and engine load. In this case, a first enhancement coefficient 'a' can be determined based on the difference between the actual oil temperature and the target oil temperature, so that the enhanced oil pump speed meets the target speed range. When the actual oil temperature decreases, the first enhancement coefficient 'b' can be re-determined based on the difference between the decreased actual oil temperature and the target oil temperature, so that the enhanced oil pump speed within the target speed range meets the target speed range. It can be understood that, according to the above adjustment method, the oil pump speed can be adjusted in real time according to the actual oil temperature to reduce the oil temperature to the target oil temperature.

[0089] In embodiments of the present invention, during the normal temperature control phase, a first enhancement coefficient can be dynamically adjusted based on the actual oil temperature and the temperature difference between the actual oil temperature and the target oil temperature. Furthermore, the oil pump speed of the target vehicle is adjusted based on the first enhancement coefficient, thereby achieving dynamic adjustment of the oil temperature. Without increasing or decreasing hardware costs, this accurately and effectively controls the engine oil temperature, resulting in improved engine performance.

[0090] Example 5

[0091] Figure 5 This is a flowchart illustrating a vehicle oil pump control method according to Embodiment 4 of the present invention. This embodiment, based on the above embodiments, specifically describes the oil pump control method corresponding to the high-temperature control stage. For detailed implementation methods, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 5 As shown, the method includes:

[0092] S510, in response to a cold start control command, obtains the operating status of the engine of the target vehicle.

[0093] S520: When the operating status is "already started", obtain the actual oil temperature of the target vehicle.

[0094] S530 determines the temperature control stage of the target vehicle based on the actual engine oil temperature.

[0095] S540: Under the condition that the temperature control stage is the high temperature control stage, obtain the oil gas content of the target vehicle.

[0096] In this embodiment, the high-temperature control stage can be a temperature control stage determined when the target vehicle is traveling at high speed on ordinary roads or uphill on steep slopes, based on the actual oil temperature reaching a relatively high level. Oil gas content can be the percentage of oil volume occupied by gases dissolved in the oil at a molecular state. The oil gas content of the target vehicle can be obtained using a device in the target vehicle that measures the engine oil gas content. Optionally, the oil gas content range of the target vehicle can be 190 kPa to 490 kPa.

[0097] S550: When the oil temperature does not exceed the preset high temperature threshold and the oil gas content does not exceed the preset gas content threshold, the oil pump speed of the target vehicle is adjusted by a preset second enhancement coefficient so that the oil pump operates at the highest speed.

[0098] In this embodiment, the preset gas content threshold can be the maximum permissible value of the gas content in the target vehicle's engine oil, such as 490 kPa. The preset high temperature threshold can be the maximum permissible value of the target vehicle's engine oil temperature. The preset second enhancement coefficient can be an adjustment coefficient preset to enhance the speed of the target vehicle's oil pump, allowing the oil pump to operate at its maximum speed. The second enhancement coefficient can be a preset fixed value. It is understood that the maximum speed can be the maximum value of the safe speed range determined based on the engine speed and engine load during the high-temperature control phase. The maximum speed of the oil pump can be the rated speed of the oil pump. The product of the actual oil pump speed and the second enhancement coefficient can be equal to the maximum value of the target oil pump speed. By operating the oil pump at its maximum speed, the target vehicle's engine oil temperature can be rapidly reduced to the target oil temperature.

[0099] Specifically, when the oil temperature does not exceed the preset high temperature threshold and the oil gas content does not exceed the preset gas content threshold, the oil pump speed of the target vehicle is adjusted by a preset second enhancement coefficient to adjust the oil pump of the target vehicle to operate at the maximum value in the target speed range, such as the rated maximum speed.

[0100] Optionally, a high-temperature warning signal can be generated and issued if the engine oil temperature is detected to exceed a preset high-temperature threshold.

[0101] In this embodiment, the high-temperature warning signal can be transmitted to the driver via an in-vehicle display device to notify them to immediately go to a repair shop for inspection. Optionally, the target vehicle can also actively reduce the engine load or coolant temperature to lower the oil temperature to a safe range.

[0102] For example, when a target vehicle is traveling at high speed on a highway for an extended period, the temperature control phase is determined to be the high-temperature control phase based on the actual oil temperature. The oil gas content and the actual oil pump speed of the target vehicle are then obtained. Since the oil gas content does not exceed a preset gas content threshold and the actual oil temperature does not exceed a preset high-temperature threshold, the oil pump speed of the target vehicle can be adjusted using a preset second enhancement coefficient to ensure the oil pump operates at the highest target speed, thereby rapidly reducing the target oil temperature.

[0103] Optionally, if the oil pump continues to operate at its highest target speed for a period of time and the oil temperature continues to rise and exceeds a preset high-temperature threshold, / or if the oil gas content exceeds a preset gas content threshold, a high-temperature warning signal can be generated and issued. In this case, the driver can safely reduce vehicle speed and proceed to a vehicle repair shop as soon as possible for engine maintenance.

[0104] In embodiments of the present invention, during the high-temperature control phase, the oil pump speed of the target vehicle can be adjusted using a preset second enhancement coefficient, provided that the oil temperature and oil gas content do not exceed a preset high-temperature threshold and a preset gas content threshold, respectively. This allows the vehicle's operating state to be determined through oil temperature and oil gas content. While ensuring relatively safe vehicle operation, the oil pump speed can be quickly adjusted using the second enhancement coefficient, thereby achieving control of the oil temperature. Simultaneously, this achieves accurate and effective control of engine oil temperature without increasing or decreasing hardware costs, resulting in improved engine performance.

[0105] Example 6

[0106] Figure 6 This is a logic block diagram of a vehicle oil pump control method provided in Embodiment 3 of the present invention. This embodiment specifically illustrates the logic framework for controlling the vehicle oil pump based on the above embodiments. For detailed implementation methods, please refer to the description of this embodiment. Technical features that are the same as or similar to those in the foregoing embodiments will not be repeated here. Figure 6 As shown, the method includes:

[0107] 1) The engine is running.

[0108] 2) Oil temperature measurement.

[0109] 3) Temperature range determination.

[0110] 4) Control strategies for low temperature, medium temperature, normal temperature and high temperature ranges.

[0111] Specifically, in response to the cold start control command, after detecting engine operation, the actual oil temperature of the target vehicle is measured, and the corresponding control strategy is entered according to the four ranges corresponding to the actual oil temperature: low temperature range, medium temperature range, normal temperature range and high temperature range.

[0112] When entering the low-temperature range, the cold start control is activated, and the electric oil pump will be stopped for a long time for a fixed value 'a'. Then it will run at a low speed for a short time for a fixed value 'b', where 'a' > 10b'. After the operation ends, the long stop will be repeated, and this process will continue until the oil temperature exceeds the low-temperature range.

[0113] When entering the mid-temperature range, the temperature rise control is activated, and the electric oil pump will be stopped for a relatively long time, a fixed value c. Then it will run at a low speed for a short time, a fixed value b. c>5b, and the engine speed is the same as the cold start control. After the operation ends, the long stop is repeated, and so on, until the oil temperature exceeds the mid-temperature range.

[0114] When entering the normal temperature range, the normal temperature control is activated, and the electric oil pump runs continuously. Its speed is multiplied by an enhancement coefficient. The target speed value changes according to the engine speed and engine load. The enhancement coefficient changes according to the actual oil temperature and the difference between the actual oil temperature and the target temperature. The speed does not exceed the preset speed threshold.

[0115] When the engine oil temperature reaches the high-temperature range, the oil gas content is monitored. If the oil gas content is less than the preset gas content threshold, emergency high-temperature control is activated. The electric oil pump runs continuously with a fixed enhancement coefficient at a relatively high value, and the electric oil pump speed reaches the maximum speed threshold to forcefully reduce the oil temperature. Once the oil temperature exceeds a certain threshold, an alarm is triggered.

[0116] In embodiments of the present invention, the actual oil temperature of an engine already in operation is acquired, a temperature control stage is determined, and the oil pump of the target vehicle is controlled according to the temperature control stage. This allows the target vehicle to control the oil temperature based on different oil pump operation adjustment strategies during the cold start control stage, warm-up control stage, normal temperature control stage, and high temperature control stage. This achieves accurate and effective control of engine oil temperature without increasing or decreasing hardware costs, resulting in improved engine performance.

[0117] Example 7

[0118] Figure 7This is a schematic diagram of the structure of a vehicle oil pump control device provided in Embodiment 7 of the present invention. Figure 7 As shown, the device includes: an engine starting module 710, an oil temperature acquisition module 720, and an oil pump operation control module 730.

[0119] Among them, the engine start module 710 is used to obtain the operating status of the engine of the target vehicle in response to the cold start control command; the oil temperature acquisition module 720 is used to obtain the actual oil temperature of the target vehicle when the operating status is already started; the oil pump operation control module 730 is used to determine the temperature control stage of the target vehicle based on the actual oil temperature, and control the oil pump of the target vehicle to operate according to the temperature control stage.

[0120] The technical solution of this invention first obtains the operating status of the target vehicle's engine in response to a cold start control command. If the engine is already running, the actual oil temperature of the target vehicle is obtained, ensuring timely and accurate monitoring of the oil temperature while the engine is running. Then, based on the actual oil temperature, the target vehicle's temperature control stage is determined, and the oil pump is controlled to operate according to this stage. This allows the target vehicle to control the oil temperature based on the oil pump's operation at different temperature control stages. This solves the problem of insufficient precision in engine oil temperature control methods. It achieves accurate and effective control of engine oil temperature without increasing hardware costs, resulting in improved engine performance.

[0121] Based on the above technical solution, the oil pump operation control module 730 may further include:

[0122] The temperature control stage building unit is used for: the temperature control stage includes a cold start control stage, a temperature rise control stage, a normal temperature control stage, and a high temperature control stage; the actual oil temperature corresponding to the cold start control stage, the temperature rise control stage, the normal temperature control stage, and the high temperature control stage increases sequentially; the oil pump continuous operation time and / or oil pump speed corresponding to the temperature control stage with a higher actual oil temperature is higher than that of the temperature control stage with a lower actual oil temperature.

[0123] Based on the above technical solution, the temperature control stage building unit may further include a cold start control stage subunit, specifically used for:

[0124] When the temperature control phase is the cold start control phase, the oil pump of the target vehicle is in a stopped state;

[0125] If the first stop time of the oil pump is detected to be in a stopped state reaches a preset first time threshold, the oil pump is controlled to run at a first speed.

[0126] If the first operating time of the oil pump is detected to reach the preset second time threshold and the temperature control stage is still the cold start control stage, the operation of controlling the oil pump of the target vehicle to be stopped is returned, wherein the first time threshold is greater than the second time threshold.

[0127] Based on the above technical solution, the temperature control stage building unit may further include a temperature rise control stage subunit, specifically used for:

[0128] When the temperature control phase is the heating control phase, the oil pump of the target vehicle is in a stopped state;

[0129] If the second shutdown duration detected by the oil pump reaches a preset third duration threshold, the oil pump is controlled to operate at the first speed.

[0130] If the second operating time of the oil pump is detected to reach the preset fourth time threshold and the temperature control stage is still the temperature rise control stage, the operation of controlling the oil pump of the target vehicle to be stopped is returned, wherein the third time threshold is greater than the fourth time threshold.

[0131] Based on the above technical solution, the temperature control stage building unit may further include a normal temperature control stage subunit, specifically used for:

[0132] When the temperature control stage is the normal temperature control stage, the speed of the oil pump of the target vehicle is adjusted by the first enhancement coefficient so that the oil pump operates at the target speed. The first enhancement coefficient is related to the actual oil temperature and the temperature difference between the actual oil temperature and the target oil temperature. The target speed is related to the engine speed and engine load.

[0133] Based on the above technical solution, the temperature control stage building unit may further include a high-temperature control stage subunit, specifically used for:

[0134] Under the condition that the temperature control stage is the high temperature control stage, obtain the oil gas content of the target vehicle;

[0135] If the oil temperature does not exceed the preset high temperature threshold and the oil gas content does not exceed the preset gas content threshold, the oil pump speed of the target vehicle is adjusted by a preset second enhancement coefficient so that the oil pump operates at the highest speed.

[0136] Based on the above technical solution, the high-temperature control stage subunit is further used for:

[0137] When the engine oil temperature is detected to exceed the preset high temperature threshold, a high temperature warning signal is generated and issued.

[0138] The vehicle oil pump control device provided in the embodiments of the present invention can execute the vehicle oil pump control method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the method execution.
