Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular, to a clutch oil filling control method, device, electronic device, and vehicle. Background Art

[0002] The clutch oil filling process generally includes a fast filling stage and a slow filling stage. The goal of the fast filling stage is to quickly inject oil into the oil circuit and fill the clutch cavity, while discharging the residual air. The fast filling stage involves two key factors: the high target pressure and the holding time. The high target pressure is a key parameter to ensure that the oil can quickly enter the system and fill the oil circuit, which determines whether the oil filling process can be successfully completed. The holding time affects whether the oil can fully enter the clutch cavity and ensures that the air can be discharged. When the fast filling stage is basically completed, the system enters the slow filling stage, and the slow filling stage mainly relies on the low target pressure. The purpose of this stage is to ensure that the oil is full while avoiding excessive pressure shock that may cause abnormal engagement or unstable operation of the clutch.

[0003] In the related art, to ensure that the clutch is filled with oil during the oil filling stage, it is necessary to monitor the oil circuit pressure in real time through a pressure sensor, and then adjust the oil filling strategy. For example, in the fast filling stage, ensure that the fast filling pressure reaches the preset high target pressure to achieve fast oil filling. The oil circuit pressure also needs to be monitored in the slow filling stage. However, due to the high price of the high-precision pressure sensor itself, especially in application scenarios with high temperature, high pressure, or high dynamic response requirements, sensors with higher durability and precision need to be used, and such sensors are even more expensive, further increasing the procurement cost.

[0048] As Figure 1 shown, a clutch oil filling control method provided by an embodiment of the present invention includes:

[0049] S100: Fill the clutch with oil based on a first preset target pressure.

[0050] Specifically, in combination with Figure 5As shown, during the rapid oil filling stage, the clutch is filled with oil based on the first preset target pressure (usually a high target pressure, such as 7 bar), which speeds up the clutch engagement process and improves the response speed. Among them, the high target pressure (P_high) can be read from the NVM (Non-Volatile Memory). The pressure can be applied in a square wave manner (the first preset target pressure, lasting for the first duration) to make the oil filling process smoother and more controlled, avoiding the impact caused by instantaneously too high pressure.

[0051] S200: When the clutch is filled with oil for the first duration based on the first preset target pressure, the clutch is filled with oil according to the second preset target pressure.

[0052] Specifically, combined with Figure 5 As shown, after the rapid oil filling stage is completed (for example, when the clutch is filled with oil for the first duration based on the first preset target pressure), it switches to the second preset target pressure (usually a low target pressure, such as 2 bar) to fill the clutch with oil to ensure smooth engagement of the clutch.

[0053] S300: When the clutch is filled with oil for the second duration according to the second preset target pressure, the oil filling completion of the clutch is detected based on the clutch slip under the third preset target pressure. When the oil filling is not completed, the first preset target pressure is adjusted, and based on the adjusted first preset target pressure, the step of filling the clutch with oil based on the first preset target pressure is executed again until the oil filling is completed. Among them, both the first preset target pressure and the third preset target pressure are greater than the second preset target pressure.

[0054] Specifically, combined with Figure 5 As shown, the basic oil filling process is completed, and the clutch is partially engaged, but it will not immediately determine that the oil filling is completed. Instead, it is necessary to detect the oil filling completion of the clutch based on the clutch slip under the third preset target pressure (greater than the second preset target pressure). Among them, when the oil filling is completed, the clutch is basically engaged, and at this time the clutch slip is small; when the oil filling is not completed, the clutch is not engaged, and at this time the clutch slip is large. When the oil filling is not completed, the first preset target pressure can be adjusted according to the second preset target pressure and the third preset target pressure to realize the dynamic adjustment of the oil filling strategy, and the clutch is refilled with oil based on the adjusted first preset target pressure, avoiding power loss or shift shock caused by insufficient oil filling, so as to improve the responsiveness and smoothness of the transmission.

[0055] In this embodiment, first, the clutch is filled with oil based on the first preset target pressure for the first duration, which can quickly fill the clutch cavity and improve the oil filling efficiency. Then, the oil filling pressure is maintained based on the second preset target pressure for the second duration, which can avoid the impact caused by excessive pressure and improve the shift smoothness. Finally, the oil filling completion is detected based on the clutch slip at the third preset target pressure. If the oil filling is not completed, the first preset target pressure is adjusted, and the clutch is refilled with oil based on the adjusted first preset target pressure. For example, the initial oil filling pressure for the next time is increased to ensure that the oil can fully enter the clutch cavity and prevent slip or power loss caused by insufficient oil filling. It is possible to achieve clutch oil filling control without using a pressure sensor, reduce manufacturing and maintenance costs, and make the oil filling process more economical, reliable, and efficient.

[0056] Optionally, the oil filling completion detection based on the third preset target pressure includes:

[0057] S310: Define that the oil filling is not completed. After maintaining the oil filling pressure at the third preset target pressure for the third duration, judge the change of the clutch slip.

[0058] Specifically, as shown in Figure 2 , in some cases, the clutch may not be fully filled, and additional oil filling completion detection is required. At this time, define that the oil filling is not completed, maintain the oil filling pressure at the third preset target pressure for the third duration (i.e., short - time pulse pressure), and observe the change of the clutch slip (the rotational speed difference between the main and driven ends).

[0059] S320: When the clutch slip is greater than the slip threshold, it is determined that the clutch oil filling is not completed.

[0060] Specifically, as shown in Figure 2 , when the clutch slip is greater than the slip threshold, it means that the clutch is still not fully filled, resulting in insufficient friction force and unable to effectively transmit power.

[0061] S330: When the clutch slip is less than or equal to the slip threshold, it is determined that the clutch oil filling is completed.

[0062] Specifically, as shown in Figure 2 , when the clutch slip is less than or equal to the slip threshold, it means that the clutch is full, the friction force is sufficient, and the slip decreases, indicating that the oil filling process is completed and the normal power transmission or shift stage can be entered.

[0063] In this optional embodiment, by accurately judging whether the oil filling is completed, the oil filling pressure can be optimized, the success rate of oil filling can be improved, the clutch slip caused by insufficient oil filling can be prevented, and the power output and clutch life can be avoided from being affected.

[0064] Optionally, the adjustment of the first preset target pressure includes:

[0065] Adjusting the first preset target pressure according to the second preset target pressure and the third preset target pressure.

[0066] Specifically, first determine the difference between the third preset target pressure and the second preset target pressure according to the second preset target pressure and the third preset target pressure, and add this difference to the original first preset target pressure to determine the adjusted first preset target pressure.

[0067] In this optional embodiment, adjusting the first preset target pressure according to the second preset target pressure and the third preset target pressure ensures the adaptability of oil filling, avoids power loss caused by insufficient oil filling of the clutch, and improves the working stability and service life of the transmission.

[0068] Optionally, the adjustment of the first preset target pressure according to the second preset target pressure and the third preset target pressure includes:

[0069] S340: Determine the pulse pressure value corresponding to the third preset target pressure according to the second preset target pressure and the third preset target pressure.

[0070] Specifically, as shown in Figure 3 , the third preset target pressure is increased by a pulse pressure value (P_Hi_Offs) on the basis of the second preset target pressure. This pulse pressure value can be the difference between the third preset target pressure and the second preset target pressure, and can be used to adjust the first preset target pressure.

[0071] S350: Increase the first preset target pressure according to the pulse pressure value.

[0072] Specifically, as shown in Figure 3 , on the basis of the first preset target pressure in this oil filling cycle, add a pulse pressure value (P_Hi_Offs) as the first preset target pressure in the fast oil filling stage of the next oil filling cycle.

[0073] In this optional embodiment, dynamically adjusting the oil filling strategy according to the actual situation ensures the adaptability of oil filling, avoids power loss caused by insufficient oil filling of the clutch, and improves the working stability and service life of the transmission.

[0074] Optionally, the second preset target pressure is less than the first preset target pressure, and the second duration is greater than the first duration.

[0075] Specifically, during the fast oil filling stage, the clutch is filled with oil based on a first preset target pressure (usually a high target pressure, such as 7 bar). After the fast oil filling stage is completed (for example, the clutch is filled with oil for a first duration based on the first preset target pressure), it is switched to a second preset target pressure (usually a low target pressure, such as 2 bar) to fill the clutch with oil for a second duration (longer than the first duration) to ensure that the clutch can be smoothly engaged.

[0076] In this alternative embodiment, by setting the target pressure and duration of the fast charging stage and the slow charging stage, the clutch engagement process is accelerated, and the oil filling process is made smoother and more controlled, avoiding impacts caused by instantaneously excessive pressure.

[0077] Optionally, before filling the oil based on the first preset target pressure, it further includes:

[0078] S001: Determine the driver's intention according to the throttle pedal signal.

[0079] Specifically, in combination with Figure 4 as shown, when filling the clutch with oil, first obtain the throttle pedal signal and determine the driver's intention according to the throttle pedal signal.

[0080] S002: When the driver's intention is an acceleration intention, control the rotational speed of the clutch driving end to be greater than the rotational speed of the clutch driven end.

[0081] Specifically, in combination with Figure 4 as shown, when the driver steps on the throttle (for example, throttle > throttle threshold), at this time the driver's intention is an acceleration intention, and the rotational speed of the clutch driving end is increased to be higher than the rotational speed of the clutch driven end to ensure that the vehicle is subject to a driving force at the moment of clutch engagement, consistent with the driver's Figure 1 intention.

[0082] S003: When the driver's intention is a deceleration intention, control the rotational speed of the clutch driving end to be less than the rotational speed of the clutch driven end.

[0083] Specifically, in combination with Figure 4 as shown, when the driver does not step on the throttle and other situations (for example, throttle ≤ throttle threshold), at this time the driver's intention is a deceleration intention, and the rotational speed of the clutch driving end is reduced to be lower than the rotational speed of the clutch driven end to ensure that the vehicle is subject to a resistance at the moment of clutch engagement, consistent with the driver's Figure 1 intention.

[0084] In this alternative embodiment, by performing pre-adjustment before filling the oil based on the first preset target pressure, suitable initial conditions are provided for the oil filling process, avoiding impacts or excessive slip caused by mismatched rotational speeds during the oil filling process.

[0085] Optionally, the driving end of the clutch is connected to the P1 motor, and the P1 motor is used to control the rotational speed of the driving end of the clutch; the driven end of the clutch is connected to the P3 motor, and the P3 motor is used to control the rotational speed of the driven end of the clutch.

[0086] Specifically, as shown in Figure 6 , taking a wet clutch as an example, the P1 motor is directly connected to the active part of the clutch (i.e., the driving end of the clutch), and the rotational speed of the active part of the clutch can be calculated according to the rotational speed of the P1 motor; the P3 motor is directly connected to the driven part of the clutch (the driven end of the clutch), and the rotational speed of the driven part of the clutch can be calculated according to the rotational speed of the P3 motor.

[0087] In this optional embodiment, by setting the P1 motor to control the rotational speed of the driving end of the clutch and the P3 motor to control the rotational speed of the driven end, the rotational speeds of both ends can be precisely matched during the oil filling stage, ensuring more sufficient oil filling and avoiding slippage or shift shock caused by insufficient oil filling.
