Abstract
Description
Technical Field
[0001] This invention relates to the field of clutch technology, and more particularly to a clutch adaptive method, apparatus, device, and storage medium. Background Technology
[0002] Dry dual-clutch transmissions are popular in the market due to their smooth shifting and good fuel economy. A dual-clutch is a transmission mechanism that can both transmit and disconnect power. Because dry dual-clutches are sensitive to complex operating conditions and greatly affected by external factors, their control is quite challenging. In clutch control, clutch position and torque transmission characteristics play a crucial role. The magnitude of the target current in the clutch actuator determines the clutch's engagement position. As vehicle mileage increases, the clutch wears down, and the relationship curve between the clutch's target position and the actuator's current changes. To achieve precise control, the clutch needs to undergo an adaptive adjustment of its position and current relationship within a certain mileage interval. Therefore, how to achieve clutch self-adaptation and obtain an accurate clutch self-adaptation curve after the adjustment process becomes a pressing problem to be solved.

[0050] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the clutch adaptive device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.
[0051] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a clutch adaptive program.

[0053] Based on the aforementioned clutch adaptive device, this embodiment of the invention provides a clutch adaptive method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the clutch adaptive method of the present invention.
[0054] In this embodiment, the clutch adaptive method includes the following steps:
[0055] Step S10: Obtain the clutch position and clutch current of the clutch to be processed during the adaptive process;
[0056] It should be noted that the executing entity in this embodiment can be a computing service device with data processing and network communication functions, such as a microprocessor or a central processing unit, or an electronic device or clutch adaptive device capable of performing the above functions. The following description uses the clutch adaptive device as an example to illustrate this embodiment and the subsequent embodiments.
[0057] It should be understood that the clutch to be processed refers to a dry dual-clutch transmission that requires adaptive operation. The adaptive process is generally carried out after the vehicle has traveled a certain distance and is in a stop.
[0058] Understandably, clutch position refers to the position when the clutch is engaged, and clutch current refers to the pressure valve current in the clutch.
[0059] Furthermore, in order to determine whether the vehicle to be processed meets the conditions for adaptive operation, in this embodiment, before step S10, the method further includes: obtaining the status information of the vehicle to be processed; when the status information meets the preset adaptive entry conditions, the clutch of the vehicle to be processed enters the adaptive process.
[0060] It should be noted that the vehicle to be processed refers to the vehicle that needs to undergo clutch adaptation, and the status information refers to the vehicle information of the vehicle to be processed before entering the clutch adaptation process, which may include the gear position of the vehicle to be processed, the gear position of the shift fork in the vehicle to be processed, etc. This embodiment does not impose specific limitations on this.
[0061] In the specific implementation, the preset adaptive entry condition refers to the pre-set adaptive entry condition, which can be set according to the actual situation. This embodiment does not impose specific restrictions on this. For example, the preset adaptive entry condition can be set as follows: (1) The handle position of the vehicle to be processed needs to be in P gear; (2) The main oil pressure is within the normal range, and there are no specific restrictions on the normal range; (3) The vehicle to be processed has no faults; (4) The shift fork in the vehicle to be processed is in the neutral position, and the vehicle to be processed is in a no-gear state; (5) The engine in the vehicle to be processed is in the Engine Off state, that is, the off state; (6) KL15 is in the power-off state, that is, the generator ignition signal is in the power-off state; (7) The clutch temperature and ambient temperature are within a reasonable range, and this embodiment does not impose specific restrictions on the reasonable range; (8) The vehicle to be processed runs a certain number of kilometers, and this embodiment does not impose specific restrictions on the certain number of kilometers.
[0062] Step S20: Construct an adaptive curve based on the clutch position and the clutch current;
[0063] It is understood that the adaptive curve refers to the curve between the clutch position and the clutch current. It can be that the clutch position is the abscissa of the adaptive curve and the clutch current is the ordinate of the adaptive curve, or it can be that the clutch position is the ordinate of the adaptive curve and the clutch current is the abscissa of the adaptive curve. This embodiment does not impose any specific restrictions on this.
[0064] Step S30: When the adaptive curve meets the preset change conditions, it is determined that the adaptive process of the clutch to be processed is complete.
[0065] It should be understood that the preset change conditions refer to the pre-set curve change conditions. This embodiment does not impose specific restrictions on this. For example, the adaptive curve may grow with a fixed slope or with a changing slope. This embodiment does not impose specific restrictions on this.
[0066] This embodiment acquires the clutch position and clutch current of the clutch under test during the adaptive process, then constructs an adaptive curve based on the clutch position and clutch current. When the adaptive curve meets preset change conditions, the adaptive process of the clutch under test is determined to be complete. This embodiment constructs an adaptive curve based on the clutch position and clutch current, obtaining a clutch adaptive curve, which is the curve between the clutch position and clutch current. When the adaptive curve meets preset change conditions, the adaptive process of the clutch under test is determined to be complete. It can determine whether clutch adaptive process is complete based on the changes in the adaptive curve, thereby achieving clutch adaptive process and obtaining an accurate clutch adaptive curve after completion.
[0067] refer to Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the clutch adaptive method of the present invention.
[0068] Based on the first embodiment described above, in this embodiment, step S10 includes:
[0069] Step S101: Obtain the set of preset flow valve current and preset pressure valve current corresponding to the clutch to be processed;
[0070] It should be understood that the clutch to be processed may include a flow valve and a pressure valve, with the flow valve corresponding to the flow valve current and the pressure valve corresponding to the pressure valve current.
[0071] It is understood that the preset flow valve current refers to the pre-set flow valve current, which in this embodiment can be set to a constant current, such as 0.5A, 0.6A, etc., and this embodiment does not impose specific limitations on this. The preset pressure valve current set refers to multiple pre-set pressure valve currents, such as [0.6 0.7 0.8 0.9 1.0 1.1]A, and this embodiment does not impose specific limitations on the magnitude and number of pressure valve currents.
[0072] Step S102: Adaptive control is performed on the clutch to be processed based on the preset flow valve current and the preset pressure valve current set;
[0073] It should be understood that the clutch to be processed can be adaptively controlled based on the preset flow valve current and preset pressure valve current sets. Specifically, the clutch engagement action is controlled so that the clutch flow valve quickly reaches the aforementioned preset flow valve current, and the flow valve maintains a constant flow rate during the clutch adaptive phase. The pressure valve current changes according to the pressure valve current in the preset pressure valve current set, that is, according to the increase of the set pressure valve current, the driven disc of the clutch engages the driving disc, and the pressure valve current changes to the preset pressure valve current of the next stage after each preset pressure valve current is maintained stably for a period of time.
[0074] Step S103: Determine the clutch position and clutch current of the clutch to be processed during the adaptive control process based on the preset pressure valve current set.
[0075] Furthermore, in order to accurately determine the clutch position and clutch current, in this embodiment, step S103 includes: obtaining the current of each pressure valve in the preset pressure valve current set; obtaining the clutch position corresponding to each clutch when the clutch to be processed is at each target current; using each pressure valve current as the clutch current and each clutch position as the clutch position.
[0076] It should be understood that the clutch current in this embodiment is the pressure valve current, and the clutch position is the position where the clutch is engaged when the pressure valve current is at different current levels.
[0077] Understandably, referring to Figure 4 , Figure 4 This is a schematic diagram of the clutch current in an embodiment of the clutch adaptive method of the present invention. Figure 4 As shown, the horizontal axis represents time, and the vertical axis represents the clutch current. The clutch current increases over time. I1-I6 represent the preset pressure valve current set, i.e., the clutch current. Figure 4 This example only uses six currents as an example; the specific number of currents, their magnitudes, and their trends are not limited in this embodiment.
[0078] Specifically, refer to Figure 5 , Figure 5 This is a schematic diagram of the clutch position according to an embodiment of the clutch adaptive method of the present invention. Figure 5As shown, the horizontal axis represents time, and the vertical axis represents the clutch position. The clutch position also increases with time. L1-L6 represent the clutch positions. The number of clutch positions corresponds to the number of clutch currents. This embodiment does not impose specific restrictions on the trend of clutch position changes.
[0079] In practical implementation, due to Figure 4 and Figure 5 The horizontal axis represents time, thus revealing the relationship between clutch current and clutch position.
[0080] This embodiment obtains a set of preset flow valve current and preset pressure valve current corresponding to the clutch to be processed. Then, it performs adaptive control on the clutch to be processed based on the preset flow valve current and preset pressure valve current sets. Finally, it determines the clutch position and clutch current of the clutch to be processed during the adaptive control process based on the preset pressure valve current set. This embodiment provides a constant flow valve current and a varying pressure valve current, and performs clutch adaptation based on the constant flow valve current and the varying pressure valve current to obtain the clutch current and clutch position during the adaptive process. Thus, it is possible to construct an adaptive curve based on the clutch position and clutch current.
[0081] refer to Figure 6 , Figure 6 This is a flowchart illustrating the third embodiment of the clutch adaptive method of the present invention.
[0082] Based on the above embodiments, in this embodiment, step S20 includes:
[0083] Step S201: Select the odd-numbered clutch positions and the even-numbered clutch positions from the clutch positions;
[0084] It should be understood that the clutch adaptation process in this embodiment may include odd clutch adaptation and even clutch adaptation. Even clutch adaptation is performed after odd clutch adaptation is completed. The two adaptation processes are the same, both of which are based on constant flow valve current and changing pressure valve current to perform clutch adaptation, only the objects of adaptation are different.
[0085] Understandably, since both odd-numbered and even-numbered clutches will complete the adaptive process, it is possible to obtain the position of the odd-numbered clutch during the adaptive process of the odd-numbered clutch and the position of the even-numbered clutch during the adaptive process of the even-numbered clutch.
[0086] Furthermore, in this embodiment, before step S201, the method further includes: obtaining the odd-numbered flow valve current and odd-numbered pressure valve current corresponding to the odd-numbered clutch in the clutches to be processed; obtaining the even-numbered flow valve current and even-numbered pressure valve current corresponding to the even-numbered clutch in the clutches to be processed; adjusting the odd-numbered flow valve current, the odd-numbered pressure valve current, the even-numbered flow valve current, and the even-numbered pressure valve current to preset current values, and opening the odd-numbered clutch and the even-numbered clutch.
[0087] It should be understood that since both odd-numbered and even-numbered clutches will complete the adaptive process, it is possible to obtain the odd-numbered flow valve current and odd-numbered pressure valve current during the adaptive process of the odd-numbered clutch, as well as the even-numbered flow valve current and even-numbered pressure valve current during the adaptive process of the even-numbered clutch.
[0088] Understandably, after the odd-number clutch current increases according to the preset odd-number pressure valve current, both the odd-number flow valve current and the odd-number pressure valve current can be adjusted to the preset current value, and the odd-number clutch can be opened. The preset current value is a pre-set current value, which can be set to 0 in this embodiment. After the even-number clutch current increases according to the preset even-number pressure valve current, both the even-number flow valve current and the even-number pressure valve current can be adjusted to the preset current value, and the even-number clutch can be opened.
[0089] Step S202: Select the odd-numbered clutch current and the even-numbered clutch current from the clutch currents;
[0090] Understandably, since both odd-numbered and even-numbered clutches will complete the adaptive process, it is possible to obtain the odd-numbered clutch current during the adaptive process of the odd-numbered clutch and the even-numbered clutch current during the adaptive process of the even-numbered clutch.
[0091] Step S203: Construct a first adaptive curve based on the odd-numbered clutch positions and the odd-numbered clutch currents, and construct a second adaptive curve based on the even-numbered clutch positions and the even-numbered clutch currents.
[0092] It should be understood that the adaptive curve in this embodiment may include a first adaptive curve, i.e., the adaptive curve corresponding to the odd number of clutches, and a second adaptive curve, i.e., the adaptive curve corresponding to the even number of clutches.
[0093] In practical implementation, a first adaptive curve can be constructed based on the odd-numbered clutch positions and odd-numbered clutch currents, representing the relationship between these two parameters. Conversely, a second adaptive curve can be constructed based on the even-numbered clutch positions and even-numbered clutch currents, representing the relationship between these two parameters.
[0094] Furthermore, in order to determine whether the adaptive function of the clutch to be processed is completed, in this embodiment, step S30 includes: obtaining a first preset number of odd clutch position sets and a second preset number of even clutch position sets in the adaptive curve; when the odd clutch position sets and the even clutch position sets meet preset change conditions, it is determined that the adaptive function of the clutch to be processed is completed.
[0095] It is understandable that after obtaining the first adaptive curve and the second adaptive curve, a first preset number of odd clutch position sets can be obtained from the first adaptive curve. The first preset number can be the same as the number of pressure valve currents in the preset pressure valve current set. A second preset number of even clutch position sets can also be obtained from the second adaptive curve. The second preset number can also be the same as the number of pressure valve currents in the preset pressure valve current set.
[0096] It should be understood that the preset change condition refers to the pre-set position value change condition, such as monotonically increasing or monotonically decreasing. In this embodiment, it can be set to monotonically increasing.
[0097] In the specific implementation, the odd-number clutch position set and the even-number clutch position set need to be monotonically increasing. Monotonically increasing can mean that L[1]<=L[2], L[2]<=L[3], L[3]<=L[4]-offset1, L[4]<=L[5]-offset2, L[5]<=L[6]-offset3. L[1]-L[6] represents the odd-number clutch position set or the even-number clutch position set. This embodiment does not impose specific restrictions on the values of offset1, offset2, and offset3. If it is monotonically increasing, the clutch to be processed will successfully adapt and the constructed adaptive curve will be stored in EEPROM. If it is not monotonically increasing, the adaptation will fail and the constructed adaptive curve will not be stored.
[0098] In practice, if any condition for entering the adaptive process is not met or the adaptive process times out, the adaptive process needs to be exited.
[0099] This embodiment selects odd and even clutch positions from the clutch positions, and then selects odd and even clutch currents from the clutch currents. A first adaptive curve is constructed based on the odd clutch positions and odd clutch currents, and a second adaptive curve is constructed based on the even clutch positions and even clutch currents. When the adaptive curves meet preset change conditions, the clutch adaptation is determined to be complete. This embodiment can determine whether clutch adaptation is complete based on the changes in the first and second adaptive curves, thereby achieving clutch adaptation and obtaining an accurate clutch adaptive curve after adaptation is completed.
[0100] Reference Figure 7 , Figure 7 This is a structural block diagram of the first embodiment of the clutch adaptive device of the present invention.

When the adaptive curve meets preset change conditions, the adaptive process of the clutch under test is determined to be complete. This embodiment constructs an adaptive curve based on the clutch position and clutch current, obtaining a clutch adaptive curve, which is the curve between the clutch position and clutch current.
