Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a flushing method for a main oil circuit solenoid valve, an electronic device, and a readable storage medium. Background Technology

[0002] Hybrid transmissions are a widely used type of new energy hybrid system in recent years, offering advantages such as low energy consumption and ample power. The structure of a hybrid transmission allows the engine to operate within its high-efficiency range, improving fuel economy. Simultaneously, the addition of dual electric motors, in parallel mode, allows them to work in conjunction with the engine to provide strong torque output, enhancing the overall vehicle performance.

[0003] Hybrid transmissions contain three valve bodies: the main oil circuit solenoid valve, the clutch solenoid valve, and the shift solenoid valve. The main oil circuit solenoid valve plays a crucial role in establishing overall pressure. Over long-term use, wear and tear on the transmission's moving components can cause fluid contamination, affecting the control quality of the main oil circuit solenoid valve and potentially causing it to stick, seriously impacting driving safety. Therefore, flushing the main oil circuit solenoid valve to prevent sticking is particularly important.

[0004] Currently, the rinsing method for clutch solenoid valves generally adopts a single rinsing mode, but this single rinsing mode is prone to causing poor rinsing effect. Summary of the Invention

[0005] The purpose of this application is to provide a flushing method, electronic device, and readable storage medium for the main oil circuit solenoid valve, so as to solve the problem of poor flushing effect in the current hybrid transmission where the main oil circuit solenoid valve is flushed using a single flushing mode.

[0006] In a first aspect, the present invention provides a flushing method for a main oil circuit solenoid valve, the method comprising: acquiring a vehicle driving state; wherein the vehicle driving state includes clutch state parameters, driving gear parameters, and driving mode parameters; determining a current flushing strategy for the main oil circuit solenoid valve based on the clutch state parameters, driving gear parameters, and driving mode parameters; wherein the flushing strategy includes a series flushing strategy and a parallel flushing strategy, wherein the flushing current value used by the main oil circuit solenoid valve in the series flushing strategy and the parallel flushing strategy are different; and flushing the vehicle's main oil circuit solenoid valve according to the current flushing strategy.

[0007] The above-designed flushing method for the main oil circuit solenoid valve first obtains the vehicle's driving status. Then, this method uses different flushing strategies to flush the main oil circuit solenoid valve under different driving conditions. Different flushing strategies use different flushing current values, so that flushing the main oil circuit solenoid valve does not affect the vehicle's driving status. The flushing strategy that is more suitable for the current driving condition is used to flush the main oil circuit solenoid valve, thereby improving the flushing effect of the main oil circuit solenoid valve under different driving conditions.

[0008] In an optional embodiment of the first aspect, the current flushing strategy of the main oil circuit solenoid valve is determined based on clutch state parameters, gear parameters, and driving mode parameters, including:

[0009] If the clutch status parameter is determined to be in the disengaged state, the driving gear parameter is the first target gear, and the driving mode is the series driving mode, then the current flushing strategy of the main oil circuit solenoid valve is determined to be the series flushing strategy.

[0010] In an optional embodiment of the first aspect, flushing the main oil circuit solenoid valve of the vehicle according to the current flushing strategy includes: flushing the main oil circuit solenoid valve with a first flushing current value; flushing the main oil circuit solenoid valve with a second flushing current value when the flushing operation time reaches a first time; and flushing the main oil circuit solenoid valve with the first flushing current value when the flushing operation time reaches a second time; wherein the first flushing current value is less than the second flushing current value, and the first flushing current value is less than the current request value of the main oil circuit solenoid valve in the parallel mode of engine and motor; the second flushing current value is the maximum flushing current of the main oil circuit solenoid valve.

[0011] In the above implementation method, when the vehicle's clutch is disengaged and the vehicle is in a series driving mode, i.e., the engine generates electricity and the electric motor is responsible for driving, this solution first flushes the main oil circuit solenoid valve with a small current, then flushes it with the maximum flushing current value that the main oil circuit solenoid valve can withstand, and finally flushes the main oil circuit solenoid valve with a small current. In this way, the flushing effect of the main oil circuit solenoid valve is improved by switching between small current and large current.

[0012] In an alternative embodiment of the first aspect, the first flushing current value includes any flushing current value from 0mA to 30mA, and the second flushing current value includes 1500mA.

[0013] In an optional embodiment of the first aspect, the current flushing strategy of the main oil circuit solenoid valve is determined based on the clutch state parameters, the driving gear parameters, and the driving mode parameters, including: if it is determined that the clutch state parameters are in an engaged state, the driving gear parameters are in the second target gear, and the driving mode is a parallel driving mode, then the current flushing strategy of the main oil circuit solenoid valve is determined to be a parallel flushing strategy.

[0014] In an optional embodiment of the first aspect, flushing the main oil circuit solenoid valve of the vehicle according to the current flushing strategy includes: flushing the main oil circuit solenoid valve with a third flushing current value; flushing the main oil circuit solenoid valve with a fourth flushing current value when the flushing operation time reaches a third time; and flushing the main oil circuit solenoid valve with a third flushing current value when the flushing operation time reaches a fourth time; wherein the third flushing current value is less than the fourth flushing current value, the third flushing current value is the current request value of the main oil circuit solenoid valve in the parallel mode of engine and motor; and the fourth flushing current value is the maximum flushing current value of the main oil circuit solenoid valve.

[0015] In the above implementation method, when the vehicle's clutch is engaged and the vehicle is in parallel driving mode (i.e., a driving mode where the engine and motor are jointly driven), this solution first flushes the main oil circuit solenoid valve using the current request value of the main oil circuit solenoid valve in the parallel engine and motor mode. Then, it flushes it using the maximum flushing current value that the main oil circuit solenoid valve can withstand (the fourth flushing current value). Finally, it flushes the main oil circuit solenoid valve using the current request value of the main oil circuit solenoid valve in the parallel engine and motor mode. Since this solution uses the current request value of the main oil circuit solenoid valve in the parallel engine and motor mode to flush the main oil circuit solenoid valve, the third flushing current value used will not affect the current parallel driving mode of the vehicle; that is, changes in the flow rate of the main oil circuit solenoid valve will not affect the operation of the clutch solenoid valve and the shift valve body. Furthermore, using the maximum flushing current value that the main oil circuit solenoid valve can withstand (the fourth flushing current value) can improve the flushing effect of the main oil circuit solenoid valve.

[0016] In an optional embodiment of the first aspect, before obtaining the vehicle's driving status, the method further includes: obtaining the vehicle's operating condition parameter information; determining whether the vehicle meets the flushing enable condition based on the vehicle's operating condition parameter information; and if it is determined that the flushing enable condition is met, then performing the step of obtaining the vehicle's driving status.

[0017] In an optional embodiment of the first aspect, the vehicle's operating condition parameter information includes current mileage information, main oil circuit solenoid valve information, and clutch solenoid valve information. Determining whether the vehicle meets the flushing enable condition based on the vehicle's operating condition parameter information includes: determining whether the main oil circuit solenoid valve is faulty based on the main oil circuit solenoid valve information; if the main oil circuit solenoid valve is not faulty, determining whether the clutch solenoid valve is flushing enabled based on the clutch solenoid valve information; if the clutch solenoid valve is not flushing enabled, determining whether the current mileage information has reached a preset mileage; if the current mileage information has reached the preset mileage, determining that the vehicle meets the flushing enable condition.

[0018] In the above implementation method, before flushing the main oil circuit solenoid valve, the solution determines whether the vehicle meets the flushing enable conditions based on the vehicle's operating condition parameters. Only when the vehicle meets the flushing enable conditions will the main oil circuit solenoid valve be flushed, thereby improving the reliability of flushing the main oil circuit solenoid valve.

[0019] Secondly, this application provides a flushing device for a main oil circuit solenoid valve. The device includes an acquisition module, a determination module, and a flushing module. The acquisition module is used to acquire the vehicle's driving state, which includes clutch state parameters, gear parameters, and driving mode parameters. The determination module is used to determine the current flushing strategy for the main oil circuit solenoid valve based on the clutch state parameters, gear parameters, and driving mode parameters. The flushing strategy includes a series flushing strategy and a parallel flushing strategy, wherein the flushing current value used by the main oil circuit solenoid valve differs between the series and parallel flushing strategies. The flushing module is used to flush the vehicle's main oil circuit solenoid valve according to the current flushing strategy.

[0020] The above-designed flushing device for the main oil circuit solenoid valve first obtains the vehicle's driving status. Then, this solution uses different flushing strategies to flush the main oil circuit solenoid valve under different driving conditions. Different flushing strategies use different flushing current values, so that flushing the main oil circuit solenoid valve does not affect the vehicle's driving status. The flushing strategy that is more adapted to the current driving state is used to flush the main oil circuit solenoid valve, thereby improving the flushing effect of the main oil circuit solenoid valve under different driving conditions.

[0021] In an optional embodiment of the second aspect, the determining module is specifically used to determine the current flushing strategy of the main oil circuit solenoid valve as a series flushing strategy if it is determined that the clutch state parameter is in a disengaged state, the driving gear parameter is the first target gear, and the driving mode is a series driving mode.

[0022] In an optional embodiment of the second aspect, the flushing module is specifically used to flush the main oil circuit solenoid valve with a first flushing current value; when the flushing operation time reaches a first time, to flush the main oil circuit solenoid valve with a second flushing current value; when the flushing operation time reaches a second time, to flush the main oil circuit solenoid valve with the first flushing current value; wherein, the first flushing current value is less than the second flushing current value, and the first flushing current value is less than the current request value of the main oil circuit solenoid valve in the parallel mode of engine and motor; the second flushing current value is the maximum flushing current value of the main oil circuit solenoid valve.

[0023] In an optional embodiment of the second aspect, the determining module is further specifically used to determine the current flushing strategy of the main oil circuit solenoid valve as a parallel flushing strategy if the clutch state parameter is determined to be in an engaged state, the driving gear parameter is the second target gear, and the driving mode is a parallel driving mode.

[0024] In an optional embodiment of the second aspect, the flushing module is further specifically used to flush the main oil circuit solenoid valve with a third flushing current value; when the flushing operation time reaches a third time, to flush the main oil circuit solenoid valve with a fourth flushing current value; when the flushing operation time reaches a fourth time, to flush the main oil circuit solenoid valve with a third flushing current value; wherein, the third flushing current value is less than the fourth flushing current value, the third flushing current value is the current request value of the main oil circuit solenoid valve in the parallel mode of engine and motor; and the fourth flushing current value is the maximum flushing current value of the main oil circuit solenoid valve.

[0025] In an optional embodiment of the second aspect, the acquisition module is further configured to acquire vehicle operating condition parameter information; the determination module is further configured to determine whether the vehicle meets the flushing enable condition based on the vehicle operating condition parameter information; the device further includes an execution module, configured to execute the step of acquiring the vehicle driving state when the determination module determines that the flushing enable condition is met.

[0026] In an optional implementation of the second aspect, the vehicle's operating parameter information includes current mileage information, main oil circuit solenoid valve information, and clutch solenoid valve information. The determining module is further specifically used to determine whether the main oil circuit solenoid valve is faulty based on the main oil circuit solenoid valve information. If the main oil circuit solenoid valve is determined not to be faulty, then the clutch solenoid valve is determined to be flush-enabled based on the clutch solenoid valve information. If the clutch solenoid valve is determined not to be flush-enabled, then the current mileage information is determined to have reached a preset mileage. If the current mileage information has reached the preset mileage, then the vehicle is determined to meet the flush-enabled condition.

[0027] Thirdly, the present invention provides an electronic device including a memory and a processor, the memory storing a computer program, and the processor executing the computer program performing any of the optional methods described in the first aspect.

[0028] Fourthly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, performs any of the optional methods described in the first aspect.

[0047] Hybrid transmissions are a widely used type of new energy hybrid system in recent years, offering advantages such as low energy consumption and ample power. The structure of a hybrid transmission allows the engine to operate within its high-efficiency range, improving fuel economy. Simultaneously, the addition of dual electric motors, in parallel mode, allows them to work in conjunction with the engine to provide strong torque output, enhancing the overall vehicle performance.

[0048] Hybrid transmissions contain three valve bodies: the main oil circuit solenoid valve, the clutch solenoid valve, and the shift solenoid valve. The main oil circuit solenoid valve plays a crucial role in establishing overall pressure. Over long-term use, wear and tear on the transmission's moving components can cause fluid contamination, affecting the control quality of the main oil circuit solenoid valve and potentially causing it to stick, seriously impacting driving safety. Therefore, flushing the main oil circuit solenoid valve to prevent sticking is particularly important.

[0049] Currently, the rinsing method for clutch solenoid valves generally adopts a single rinsing mode, but this single rinsing mode is prone to causing poor rinsing effect.

[0050] Based on the above problems, this application designs a flushing method, electronic device, and readable storage medium for the main oil circuit solenoid valve. First, the driving state of the vehicle is acquired. Then, this solution uses different flushing strategies to flush the main oil circuit solenoid valve under different driving states. Different flushing strategies use different flushing current values, so that flushing the main oil circuit solenoid valve does not affect the driving state of the vehicle. The flushing strategy is more adapted to the current driving state to flush the main oil circuit solenoid valve, thereby improving the flushing effect of the main oil circuit solenoid valve under different driving states.

[0051] Based on the above ideas, this application first provides a flushing method for the main oil circuit solenoid valve. This method can be applied to a computing device, specifically a vehicle controller, vehicle control chip, tram control platform, etc. Figure 1 As shown, this method can be implemented in the following ways, including:

[0052] Step S100: Obtain the vehicle's driving status.

[0053] Step S110: Determine the current flushing strategy of the main oil circuit solenoid valve based on the clutch status parameters, driving gear parameters, and driving mode parameters.

[0054] Step S120: According to the current flushing strategy, flush the main oil circuit solenoid valve of the vehicle.

[0055] The vehicles mentioned above refer to current hybrid electric vehicles (HEVs), which are vehicles whose drive systems consist of two or more individual drive systems that can operate simultaneously. "Scrubbing" refers to the electrical flushing of the solenoid valves in the vehicle's transmission, addressing any sticking caused by factors such as transmission fluid viscosity, oil film tension within the oil chamber, and impurities.

[0056] The hybrid transmission has three valve bodies: the main oil circuit solenoid valve, the clutch solenoid valve, and the shift solenoid valve. The main oil circuit solenoid valve is responsible for establishing the overall pressure. This solution mainly focuses on the flushing control process of the main oil circuit solenoid valve in the hybrid transmission.

[0057] In the above embodiments, when the hybrid vehicle is in operation, this solution can first obtain the vehicle's driving status, which may include clutch status parameters, gear parameters, and driving mode parameters. The clutch status parameters indicate whether the clutch is currently disengaged or engaged. The gear parameters indicate the current gear of the vehicle, such as neutral, first gear, second gear, etc. The driving mode parameters indicate the current driving mode of the vehicle, such as series driving mode and parallel driving mode. The series driving mode indicates that the vehicle's engine generates electricity and the vehicle's electric motor is responsible for driving. The parallel driving mode indicates that the vehicle's generator and electric motor are driven together.

[0058] With the vehicle's driving status obtained through the above methods, this solution can determine the current flushing strategy of the main oil circuit solenoid valve based on clutch status parameters, driving gear parameters, and driving mode parameters. This current flushing strategy can include a series flushing strategy and a parallel flushing strategy, with different flushing current values ​​used for the main oil circuit solenoid valve in the two strategies.

[0059] If the current flushing strategy of the main oil circuit solenoid valve is determined by the above method, this solution flushes the main oil circuit solenoid valve according to the current flushing strategy, thereby cleaning the main oil circuit solenoid valve.

[0060] The above-designed flushing method for the main oil circuit solenoid valve first obtains the vehicle's driving status. Then, this method uses different flushing strategies to flush the main oil circuit solenoid valve under different driving conditions. Different flushing strategies use different flushing current values, so that flushing the main oil circuit solenoid valve does not affect the vehicle's driving status. The flushing strategy that is more suitable for the current driving condition is used to flush the main oil circuit solenoid valve, thereby improving the flushing effect of the main oil circuit solenoid valve under different driving conditions.

[0061] As described above, this solution can determine the current flushing strategy based on clutch state parameters, gear parameters, and driving mode parameters. One possible implementation method is... Figure 2 As shown, this scheme can determine the current flushing strategy in the following ways, including:

[0062] Step S200: If the clutch state parameter is determined to be in the disengaged state, the driving gear parameter is the first target gear, and the driving mode is the series driving mode, then the current flushing strategy of the main oil circuit solenoid valve is determined to be the series flushing strategy.

[0063] In the above embodiments, the first target gear can be neutral. That is, if the solution determines that the clutch is disengaged, the driving gear is neutral, and the driving mode is a series driving mode, the solution adopts a series flushing strategy to flush the main oil circuit solenoid valve.

[0064] Specifically, such as Figure 2 As shown, this scheme can employ a series flushing strategy for flushing in the following manner:

[0065] Step S210: The main oil circuit solenoid valve is flushed using the first flushing current value.

[0066] Step S220: When the flushing operation time reaches the first time, the main oil circuit solenoid valve is flushed with the second flushing current value.

[0067] Step S230: When the flushing operation time reaches the second time, the main oil circuit solenoid valve is flushed again using the first flushing current value.

[0068] In the above embodiments, the first flushing current value is less than the second flushing current value, and the first flushing current value is less than the current request value of the main oil circuit solenoid valve in the parallel mode of engine and motor; the second flushing current value is the maximum flushing current of the main oil circuit solenoid valve. The first flushing current value includes any flushing current value from 0mA to 30mA, and the second flushing current value includes 1500mA.

[0069] As a possible example, assuming the first time is 0.1 seconds, the second time is 1.1 seconds, the first flushing current value is 0mA, and the second flushing current value is 1500mA, the above implementation method can be specifically as follows: when the vehicle is driving in series driving mode, the main oil circuit solenoid valve is flushed with a low current of 0mA. When the running time reaches 0.1s, this solution flushes the main oil circuit solenoid valve with a high current of 1500mA. When the running time reaches 1.1s, this solution flushes the main oil circuit solenoid valve again with a low current of 0mA.

[0070] It should be noted that this solution allows setting a flushing time, meaning the flushing process will automatically stop once the flushing time is reached. Assuming the flushing time is 2 seconds, when the running time reaches 1.1 seconds, this solution will flush the main oil circuit solenoid valve again with a low current of 0mA until the flushing time reaches 2 seconds and then stop.

[0071] In addition, this solution can also determine the status of the clutch solenoid valve and the main oil circuit solenoid valve during the flushing process. If the clutch solenoid valve or the main oil circuit solenoid valve malfunctions, this solution will end the flushing process. For example, if a low current of 0mA is used to flush the main oil circuit solenoid valve, and the running time reaches 0.1s, this solution will then use a high current of 1500mA to flush the main oil circuit solenoid valve. However, if the flushing time reaches 1s and this solution detects a malfunction in the clutch solenoid valve or the main oil circuit solenoid valve, this solution will stop the flushing process.

[0072] In the above implementation method, when the vehicle's clutch is disengaged and the vehicle is in a series driving mode, i.e., the engine generates electricity and the electric motor is responsible for driving, this solution first flushes the main oil circuit solenoid valve with a small current, then flushes it with the maximum flushing current value that the main oil circuit solenoid valve can withstand, and finally flushes the main oil circuit solenoid valve with a small current. In this way, the flushing effect of the main oil circuit solenoid valve is improved by switching between small current and large current.

[0073] As another possible implementation, such as Figure 3 As shown, this scheme can determine the current flushing strategy in the following ways, including:

[0074] Step S300: If the clutch state parameter is determined to be engaged, the driving gear parameter is the second target gear, and the driving mode is parallel driving mode, then the current flushing strategy of the main oil circuit solenoid valve is determined to be the parallel flushing strategy.

[0075] In the above embodiments, the second target gear can be the first gear or the second gear of the vehicle. That is, if this solution determines that the clutch is engaged, the gear is the first or second gear, and the driving mode is the parallel driving mode, this solution adopts a parallel flushing strategy to flush the main oil circuit solenoid valve.

[0076] In the above situation, for step S120, this solution can implement the parallel flushing strategy in the following ways:

[0077] Step S310: The main oil circuit solenoid valve is flushed using the third flushing current value.

[0078] Step S320: When the flushing operation time reaches the third time, the main oil circuit solenoid valve is flushed with the fourth flushing current value.

[0079] Step S330: When the flushing operation time reaches the fourth time, the main oil circuit solenoid valve is flushed using the third flushing current value.

[0080] In the above implementation method, the third flushing current value is less than the fourth flushing current value.

[0081] In this parallel driving mode, the engine and motor drive each other in parallel. For the engine and motor to be in parallel operation, the clutch must be engaged. For the clutch to be engaged, the main oil circuit solenoid valve pressure must be at a certain level. This requires the main oil circuit solenoid valve to have a certain current request value, which is the third flushing current value. In other words, the third flushing current value is the current request value of the main oil circuit solenoid valve in the engine and motor parallel operation mode. The fourth flushing current value is the maximum flushing current of the main oil circuit solenoid valve, for example, the fourth flushing current value may include 1500mA.

[0082] As a possible example, assuming the first time is 0.1 seconds, the second time is 1.1 seconds, and the fourth flushing current value is 1500mA, the above implementation method can be specifically described as follows: when the vehicle is driving in parallel driving mode, the main oil circuit solenoid valve is flushed with a third flushing current value. When the running time reaches 0.1s, this solution flushes the main oil circuit solenoid valve with a large current of 1500mA. When the running time reaches 1.1s, this solution flushes the main oil circuit solenoid valve again with a third flushing current value.

[0083] It should be noted that this solution can also set the flushing time during the parallel flushing strategy. That is, the flushing process will automatically stop when the flushing time is reached. Assuming the flushing time is 2 seconds, when the running time reaches 1.1 seconds, this solution will use a third flushing current to flush the main oil circuit solenoid valve again until the flushing time reaches 2 seconds and then stop.

[0084] Furthermore, this solution can also determine the status of the clutch solenoid valve and the main oil circuit solenoid valve during the parallel flushing strategy. If a malfunction occurs in either the clutch solenoid valve or the main oil circuit solenoid valve, the flushing process will end. For example, when flushing the main oil circuit solenoid valve using a third flushing current, if the running time reaches 0.1s, this solution will flush the main oil circuit solenoid valve with a high current of 1500mA. However, if the flushing time reaches 1s and this solution detects a malfunction in either the clutch solenoid valve or the main oil circuit solenoid valve, the flushing process will stop.

[0085] In the above implementation method, when the vehicle's clutch is engaged and the vehicle is in parallel driving mode (i.e., a driving mode where the engine and motor are jointly driven), this solution first flushes the main oil circuit solenoid valve using the current request value of the main oil circuit solenoid valve in the parallel engine and motor mode. Then, it flushes it using the maximum flushing current value that the main oil circuit solenoid valve can withstand (the fourth flushing current value). Finally, it flushes the main oil circuit solenoid valve using the current request value of the main oil circuit solenoid valve in the parallel engine and motor mode. Since this solution uses the current request value of the main oil circuit solenoid valve in the parallel engine and motor mode to flush the main oil circuit solenoid valve, the third flushing current value used will not affect the current parallel driving mode of the vehicle; that is, changes in the flow rate of the main oil circuit solenoid valve will not affect the operation of the clutch solenoid valve and the shift valve body. Furthermore, using the maximum flushing current value that the main oil circuit solenoid valve can withstand (the fourth flushing current value) can improve the flushing effect of the main oil circuit solenoid valve.

[0086] In an optional implementation of this embodiment, such as Figure 4 As shown, before obtaining the vehicle's driving status, this solution can also determine whether the vehicle meets the conditions for enabling flushing, which may include:

[0087] Step S400: Obtain the vehicle's operating condition parameter information.

[0088] Step S410: Based on the vehicle's operating parameters, determine whether the vehicle meets the flushing enable conditions. If it does, proceed to step S100.

[0089] In the above embodiments, the vehicle's operating condition parameter information may include the vehicle's current mileage information, the main oil circuit solenoid valve information, and the clutch solenoid valve information. The vehicle's current mileage information indicates the mileage traveled after the vehicle starts. The main oil circuit solenoid valve information indicates whether there is any fault information in the main oil circuit solenoid valve, such as whether the main oil circuit solenoid valve is stuck, leaking, or disengaged. The clutch solenoid valve information indicates whether the clutch solenoid valve has flushing capability.

[0090] In the above situation, for step S410, this solution can specifically determine whether the vehicle meets the flushing enable condition in the following way: First, this solution determines whether the main oil circuit solenoid valve is faulty based on the information of the main oil circuit solenoid valve; if it is determined that the main oil circuit solenoid valve is not faulty, then it determines whether the clutch solenoid valve is flushing enabled based on the information of the clutch solenoid valve; if it is determined that the clutch solenoid valve is not flushing enabled, then it determines whether the current mileage information has reached the preset mileage; if it is determined that the current mileage information has reached the preset mileage, then it is determined that the vehicle meets the flushing enable condition.

[0091] In the above implementation method, if it is determined that the main oil circuit solenoid valve is not faulty, the clutch solenoid valve is not flushing enabled, and the current mileage has reached the preset mileage, then the vehicle is deemed to meet the flushing enable condition. The preset mileage can be adaptively adjusted according to actual conditions; for example, the preset mileage can be 50 kilometers, 60 kilometers, etc.

[0092] In the above implementation method, before flushing the main oil circuit solenoid valve, the solution determines whether the vehicle meets the flushing enable conditions based on the vehicle's operating condition parameters. Only when the vehicle meets the flushing enable conditions will the main oil circuit solenoid valve be flushed, thereby improving the reliability of flushing the main oil circuit solenoid valve.

[0098] According to some embodiments of this application, the flushing module 520 is further specifically used to control the main oil circuit solenoid valve to flush using a third flushing current value; when the flushing operation time reaches a third time, control the main oil circuit solenoid valve to flush using a fourth flushing current value; when the flushing operation time reaches a fourth time, control the main oil circuit solenoid valve to flush using a third flushing current value; wherein, the third flushing current value is less than the fourth flushing current value, the third flushing current value is the current request value of the main oil circuit solenoid valve in the parallel mode of engine and motor; the fourth flushing current value is the maximum flushing current value of the main oil circuit solenoid valve.

[0099] According to some embodiments of this application, the acquisition module 500 is further configured to acquire vehicle operating condition parameter information; the determination module 510 is further configured to determine whether the vehicle meets the flushing enable condition based on the vehicle operating condition parameter information; the device further includes an execution module 530, configured to execute the step of acquiring the vehicle driving state when the determination module determines that the flushing enable condition is met.

[0100] According to some embodiments of this application, the vehicle's operating parameter information includes current mileage information, main oil circuit solenoid valve information, and clutch solenoid valve information; the determining module 510 is further specifically used to determine whether the main oil circuit solenoid valve is faulty based on the main oil circuit solenoid valve information; if it is determined that the main oil circuit solenoid valve is not faulty, then it determines whether the clutch solenoid valve is flushing enabled based on the clutch solenoid valve information; if it is determined that the clutch is not flushing enabled, then it determines whether the current mileage information has reached a preset mileage; if it is determined that the current mileage information has reached a preset mileage, then it determines that the vehicle meets the flushing enable condition.
