Description

Technical Field

[0001] This invention relates to the field of vehicle clutch technology, and in particular to a method, apparatus, equipment, and storage medium for processing clutch engagement teeth. Background Technology

[0002] The 9AT hydraulic transmission primarily utilizes the engagement and disengagement of four multi-plate clutches and two dog clutches to create nine forward gears and one reverse gear. Replacing the traditional multi-plate clutches with dog clutches overcomes space and weight limitations. Because dog clutches virtually eliminate the drag losses inherent in multi-plate clutches, the 9AT offers a significant advantage in transmission efficiency compared to traditional automatic transmissions.

[0003] A dog clutch consists of long and short teeth arranged alternately along the axial direction. It achieves a rigid mechanical connection through the meshing of these teeth. Unlike friction-based power transmission, the dog clutch relies on a rigid connection, requiring precise control of the speed difference during engagement. All speed synchronization is handled electronically. During gear shifting, the dog clutch demands meticulous control to ensure engagement within a specified time, while also preventing any impact during engagement. If the dog clutch fails to reach the intended position, the transmission will lose gear and power, compromising driving safety. Currently, the industry lacks research on strategies for handling dog clutch engagement during gear shifting.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a method, apparatus, device, and storage medium for handling clutch gear engagement and gear jamming, aiming to provide a method for handling gear jamming when a dog-tooth clutch engages gear engagement.

[0006] To achieve the above objectives, the present invention provides a method for handling clutch engagement gear jamming, the method comprising the following steps:

[0007] When the engine is detected to be running and the vehicle is in a fault-free state, a clutch engagement command is output, which is used to control the dog clutch A to engage.

[0008] According to the clutch engagement command, the clutches B and C are depressurized, and during the depressurization process, it is detected whether the dog clutch A has reached the engagement position.

[0009] If not, it is determined that the dog clutch A is stuck, and the dog clutch A is processed based on the clutch stuck processing strategy. The clutch stuck processing strategy is a strategy to adjust clutches D and E. Clutches B, C, D and E are multi-plate clutches.

[0010] Optionally, the step of outputting a clutch engagement command when the engine is detected to be running and the vehicle is in a fault-free state includes:

[0011] When the engine is detected to be running and the vehicle is in a fault-free state, shift the vehicle into Drive (D) gear.

[0012] The rotational speed of the dog clutch A is controlled by clutches B and C, and the speed difference between the two ends of the dog clutch A is monitored.

[0013] If the speed difference is less than a preset threshold, the dog clutch A is determined to meet the engagement condition, and a clutch engagement command is output.

[0014] Optionally, the step of determining that the dog clutch A is stuck if not, and performing stuck clutch A treatment based on a clutch stuck clutch treatment strategy, includes:

[0015] If the dog clutch A does not reach the engagement position, it is determined that the dog clutch A is stuck, and the type of stuck tooth is determined.

[0016] If the tooth jamming type is a tooth tip jamming type, then the dog tooth clutch A is jammed based on the first clutch jamming processing strategy. The tooth tip jamming type includes long tooth tip long tooth type and long tooth tip short tooth type.

[0017] Optionally, the first clutch tooth jamming handling strategy includes:

[0018] The speed difference of the dog clutch A is adjusted by the clutch D and the clutch E;

[0019] Increase the pressure on clutch D and decrease the pressure on clutch E, while simultaneously increasing the main hydraulic pressure of the vehicle.

[0020] Optionally, after determining the type of tooth jamming when the dog clutch A experiences tooth jamming, the method further includes:

[0021] If the tooth jamming type is a spline interlocking tooth jamming type, then the dog tooth clutch A is jammed based on the second clutch tooth jamming processing strategy.

[0022] Optionally, the second clutch tooth jamming handling strategy includes:

[0023] The circumferential force on the dog clutch A is adjusted by changing the torque of the clutches D and E.

[0024] The transmitted torque of the dog clutch A is captured in real time based on the circumferential force after the adjustment of the dog clutch A. When the transmitted torque is detected to be zero, the torque of the clutch D and the clutch E is stopped from being changed.

[0025] Optionally, after the step of determining that the dog clutch A is stuck and performing stuck clutch A based on the clutch stuck clutch handling strategy if no, the method further includes:

[0026] When the clutch tooth jamming treatment strategy is detected to be activated, the main hydraulic pressure tooth jamming treatment strategy is also activated. The main hydraulic pressure tooth jamming treatment strategy is used to adjust the main hydraulic pressure of the vehicle.

[0027] Furthermore, to achieve the above objectives, the present invention also proposes a clutch shifting tooth processing device, the clutch shifting tooth processing device comprising:

[0028] The command output module is used to output a clutch engagement command when the engine is detected to be running and the vehicle is in a fault-free state. The clutch engagement command is used to control the dog clutch A to engage.

[0029] The position detection module is used to depressurize clutches B and C according to the clutch engagement command, and to detect whether the dog clutch A has reached the engagement position during the depressurization process.

[0030] The tooth jamming processing module is used to determine if the dog clutch A is jammed if not, and to perform tooth jamming processing on the dog clutch A based on the clutch tooth jamming processing strategy. The clutch tooth jamming processing strategy is a strategy to adjust clutches D and E. Clutches B, C, D and E are multi-plate clutches.

[0031] Furthermore, to achieve the above objectives, the present invention also proposes a clutch shifting gear jamming device, the device comprising: a memory, a processor, and a clutch shifting gear jamming processing program stored in the memory and executable on the processor, the clutch shifting gear jamming processing program being configured to implement the steps of the clutch shifting gear jamming processing method described above.

[0032] Furthermore, to achieve the above objectives, the present invention also proposes a storage medium storing a clutch shifting gear locking processing program, wherein when the clutch shifting gear locking processing program is executed by a processor, the steps of the clutch shifting gear locking processing method described above are implemented.

[0033] This invention outputs a clutch engagement command when the engine is detected to be running and the vehicle is in a fault-free state. This clutch engagement command controls the engagement of the dog clutch A. Based on the clutch engagement command, clutches B and C are depressurized, and during the depressurization process, it is detected whether the dog clutch A has reached the engagement position. If not, it is determined that the dog clutch A is jammed, and a jamming handling strategy is implemented for the dog clutch A. The jamming handling strategy involves adjusting clutches D and E. Clutches B, C, D, and E are multi-plate clutches. Because this invention detects the state of the dog clutch A after outputting the clutch engagement command and performs jamming handling based on the clutch jamming handling strategy when jamming is detected, it avoids the technical drawback of gear loss caused by the dog clutch failing to reach the expected position, thereby improving vehicle driving safety.

[0044] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the clutch shifting gear processing device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0045] 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 shifting and gear-gripping processing program.

[0046] exist Figure 1 In the clutch shifting and gear-clamping processing device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the clutch shifting and gear-clamping processing device of the present invention can be set in the clutch shifting and gear-clamping processing device. The clutch shifting and gear-clamping processing device calls the clutch shifting and gear-clamping processing program stored in the memory 1005 through the processor 1001 and executes the clutch shifting and gear-clamping processing method provided in the embodiment of the present invention.

[0047] This invention provides a method for handling clutch engagement gear jamming, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the clutch gear engagement and tooth jamming treatment method of the present invention.

[0048] In this embodiment, the clutch engagement gear jamming treatment method includes the following steps:

[0049] Step S10: When the engine is detected to be running and the vehicle is in a fault-free state, a clutch engagement command is output. The clutch engagement command is used to control the dog clutch A to engage.

[0050] It should be noted that the executing entity of the method in this embodiment can be a terminal device with command output, data processing, and program execution functions, such as a smartphone or computer, or an electronic device with the same or similar functions, such as the clutch shifting gear processing device mentioned above. The following description uses the clutch shifting gear processing device (hereinafter referred to as the processing device) as an example to illustrate this embodiment and the following embodiments.

[0051] Understandably, the aforementioned clutch engagement command could be a command that controls the connection between the engine and the transmission by controlling the engagement of the dog clutch A.

[0052] It should be understood that for a vehicle to be in a fault-free state, it should at least meet the following requirements: the engine, transmission, drive system, and other power components are not faulty; the brake pads, brake discs, brake fluid, and other braking components are not faulty; the suspension components, steering components, and other components are not faulty; and the battery, alternator, wiring, and other components (if present) are not faulty. Of course, since the definition of a fault-free state may differ between different vehicle models, other requirements that demonstrate a vehicle is in a fault-free state also apply to this embodiment, and will not be elaborated upon here.

[0053] Step S20: Depressurize clutches B and C according to the clutch engagement command, and detect whether the dog clutch A has reached the engagement position during the depressurization process.

[0054] In a specific implementation, after the vehicle receives the clutch engagement command, it can use the clutch engagement command to call the pressure vessel to release the pressure of clutch B and clutch C, or it can call the power booster pump, electric oil pump, compensation tank, etc. to release the pressure of clutch B and clutch C. This embodiment does not limit this.

[0055] Step S30: If not, it is determined that the dog clutch A is stuck, and the dog clutch A is processed based on the clutch stuck processing strategy. The clutch stuck processing strategy is a strategy to adjust clutch D and clutch E. Clutch B, clutch C, clutch D and clutch E are multi-plate clutches.

[0056] It should be noted that clutches B, C, D, and E mentioned above are all multi-plate clutches. These multi-plate clutches can consist of multiple clutch plates (also called friction plates or clutch discs), which can be made of friction materials. The clutch plates are pressed together under the action of the clutch pressure plate, forming a connection between the engine and the transmission. When the clutch is engaged, the clutch plates are pressed together, transmitting torque; when the clutch is disengaged, the clutch plates separate, cutting off torque transmission.

[0057] In practical implementation, due to factors such as oil temperature, system oil pressure, turbo torque, and hardware during gear shifting, the dog tooth position may not reach the engagement position after the dog tooth drive command is given, affecting the gear shifting response speed. Therefore, this embodiment proposes the above-mentioned clutch stuck-tooth handling strategy, which identifies the stuck-tooth clutch and coordinates with the clutch action and main oil pressure to handle the stuck-tooth clutch, improving the gear shifting quality and robustness. Specifically, when shifting from P / N to the power forward gear D, during the process of engaging the dog tooth clutch A with the auxiliary BCD clutch, if the dog tooth clutch A is detected not reaching the engagement position during the non-working clutch depressurization process after the clutch engagement command has been given, the dog tooth stuck-tooth clutch is identified (this can be identified by the dog tooth position sensor). At this time, the processing device can handle the stuck-tooth clutch through the cooperation of clutch E and clutch D.

[0058] This embodiment outputs a clutch engagement command when the engine is detected to be running and the vehicle is in a fault-free state. This clutch engagement command controls the engagement of the dog clutch A. Based on the clutch engagement command, clutches B and C are depressurized, and during the depressurization process, it is detected whether the dog clutch A has reached the engagement position. If not, it is determined that the dog clutch A is jammed, and a jamming handling strategy is implemented to handle the jamming of the dog clutch A. The jamming handling strategy involves adjusting clutches D and E. Clutches B, C, D, and E are multi-plate clutches. Because this embodiment detects the state of the dog clutch A after outputting the clutch engagement command and handles the jamming of the dog clutch A based on the clutch jamming handling strategy when jamming is detected, it avoids the technical drawback of gear loss caused by the dog clutch failing to reach the expected position, thereby improving vehicle driving safety.

[0059] refer to Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the clutch gear engagement and tooth jamming treatment method of the present invention.

[0060] Based on the first embodiment described above, in this embodiment, in order to more accurately determine whether the dog clutch A meets the engagement conditions, step S10 may include:

[0061] Step S101: When the engine is detected to be running and the vehicle is in a fault-free state, shift the vehicle into D gear.

[0062] In practice, when the engine starts, there is no driving force transmitted to the wheels in the vehicle's transmission system, and there is no direct connection between the engine and the transmission system. If the vehicle is in a fault-free state at this time, the clutch plates in the transmission can engage with the transmission housing to transmit engine power to the transmission, thereby enabling the vehicle to be engaged in D (Drive) gear.

[0063] Step S102: Control the rotational speed of the dog clutch A through clutch B and clutch C, and monitor the speed difference between the two ends of the dog clutch A.

[0064] In a practical implementation, the aforementioned clutches B and C can form a mechanical chain, thereby transmitting the rotational speed to the dog clutch A through mechanical coupling, and thus controlling the rotational speed of the dog clutch A.

[0065] Step S103: If the speed difference is less than a preset threshold, the dog clutch A is determined to meet the engagement condition, and a clutch engagement command is output.

[0066] It should be understood that when the speed difference is less than the preset threshold, it indicates that the speeds at both ends of the dog clutch A have been synchronized. Therefore, it can be determined that the dog clutch A meets the engagement conditions and can output a clutch engagement command.

[0067] Furthermore, in this embodiment, to further improve the efficiency of handling tooth jamming when the dog clutch jams, after step S30, the following may be included:

[0068] Step S40: When the clutch tooth jamming treatment strategy is detected to be activated, the main hydraulic pressure tooth jamming treatment strategy is also activated. The main hydraulic pressure tooth jamming treatment strategy is used to adjust the main hydraulic pressure of the vehicle.

[0069] In practical implementation, the main hydraulic pressure jamming strategy can also be activated when the clutch tooth jamming strategy is activated. In the main hydraulic pressure jamming strategy, the first stage is the main hydraulic pressure requested during the clutch charging stage; the second stage is the main hydraulic pressure requested when the dog clutch A begins to engage. If the dog clutch A is not engaged after a certain period following the clutch engagement command, the main hydraulic pressure is increased to the target value (i.e., the third stage); during the pre-charging of clutch E, the target value of the main hydraulic pressure is reduced, requesting a lower main hydraulic pressure. This is because reducing the main hydraulic pressure during the clutch pre-charging stage saves oil and prevents an unexpected drop in the main hydraulic circuit pressure; after clutch E completes pre-charging, the main hydraulic pressure jamming enters the fifth stage, where the target main hydraulic pressure is set to the maximum value. Increasing the main hydraulic pressure increases the axial force of the dog clutch A, which is beneficial for the engagement of the dog clutch A; after the dog clutch A maintains engagement and establishes power flow, the main hydraulic pressure jamming enters the sixth stage, where the target main hydraulic pressure is 0 bar.

[0070] This embodiment involves engaging the vehicle in Drive (D) when the engine is detected to be running and the vehicle is in a fault-free state. The rotational speed of the dog clutch A is controlled via clutches B and C, and the speed difference between the two ends of dog clutch A is monitored. If the speed difference is less than a preset threshold, dog clutch A is deemed to meet the engagement conditions, and a clutch engagement command is output. When the clutch jamming handling strategy is activated, a main hydraulic pressure jamming handling strategy is also activated simultaneously to regulate the vehicle's main hydraulic pressure. This embodiment improves the efficiency of jamming handling by controlling the rotational speed of dog clutch A via clutches B and C, thereby ensuring that dog clutch A meets the engagement conditions and outputs a clutch engagement command. Simultaneously, the combination of the clutch jamming handling strategy and the main hydraulic pressure jamming handling strategy improves the efficiency of the jamming process.

[0071] refer to Figure 4 , Figure 4 This is a flowchart illustrating the third embodiment of the clutch gear engagement and tooth jamming treatment method of the present invention.

[0072] Based on the above embodiments, in this embodiment, in order to implement different clutch jamming treatment strategies for different jamming types, thereby enabling more targeted jamming treatment of the dog-tooth clutch A, step S30 may include:

[0073] Step S301: If the dog clutch A does not reach the engagement position, it is determined that the dog clutch A is stuck, and the type of stuck tooth is determined.

[0074] In practical implementation, the type of gear jamming in the dog clutch A can be determined based on the gear state when gear jamming occurs. (Reference) Figure 5 , Figure 5 This is a schematic diagram of the gear state of the dog-tooth clutch A in the clutch engagement and gear jamming treatment method of the present invention. From Figure 5 As can be seen, disengagement and engagement are normal states of the dog clutch A, while tooth tip jamming (including long tooth tipping long tooth and long tooth tipping short tooth) and spline interlocking jamming are jamming states of the dog clutch A.

[0075] Step S302: If the tooth jamming type is a tooth tip jamming type, then the dog tooth clutch A is jammed based on the first clutch tooth jamming processing strategy. The tooth tip jamming type includes long tooth tip long tooth type and long tooth tip short tooth type.

[0076] In a specific implementation, the above-mentioned first clutch tooth jamming handling strategy may include: adjusting the speed difference of the dog-tooth clutch A through the clutch D and the clutch E; increasing the pressure on the clutch D and decreasing the pressure on the clutch E, while increasing the main oil pressure of the vehicle.

[0077] Step S303: If the tooth jamming type is a spline interlocking tooth jamming type, then the dog tooth clutch A is jammed based on the second clutch tooth jamming processing strategy.

[0078] In a specific implementation, the above-mentioned second clutch tooth jamming handling strategy may include: adjusting the circumferential force of the dog clutch A by changing the torque of the clutch D and the clutch E; capturing the transmitted torque of the dog clutch A in real time according to the adjusted circumferential force of the dog clutch A; and stopping the change of the torque of the clutch D and the clutch E when the transmitted torque is detected to be zero.

[0079] This embodiment determines that the dog clutch A is jammed if it fails to reach the engagement position, and identifies the type of jamming. If the jamming type is a tip-jamming type, a first clutch jamming treatment strategy is applied to the dog clutch A. The tip-jamming type includes long-tooth-to-long-tooth and long-tooth-to-short-tooth types. If the jamming type is a spline interlocking type, a second clutch jamming treatment strategy is applied to the dog clutch A. The first clutch jamming treatment strategy includes: adjusting the speed difference between the dog clutch A and clutches D and E; increasing the pressure on clutch D and decreasing the pressure on clutch E; and simultaneously increasing the vehicle's main hydraulic pressure. The second clutch jamming handling strategy includes: adjusting the circumferential force on the dog clutch A by changing the torque of clutch D and clutch E; capturing the transmitted torque of the dog clutch A in real time based on the adjusted circumferential force; and stopping the change of torque on clutch D and clutch E when the transmitted torque is detected to be zero. In this embodiment, the above method combines the first and second clutch jamming handling strategies to implement different clutch jamming handling strategies for different jamming types, thereby enabling more targeted jamming handling of the dog clutch A in a jammed state, and thus improving vehicle driving safety.

[0080] Furthermore, this embodiment of the invention also proposes a storage medium storing a clutch shifting gear jamming process program, which, when executed by a processor, implements the steps of the clutch shifting gear jamming method described above.

[0081] Reference Figure 6 , Figure 6 This is a structural block diagram of the first embodiment of the clutch shifting and gear-clamping processing device of the present invention.

[0084] The position detection module 602 is used to depressurize clutch B and clutch C according to the clutch engagement command, and detect whether the dog clutch A has reached the engagement position during the depressurization process.

[0085] The tooth jamming processing module 603 is used to determine if the dog clutch A is jammed if not, and to perform tooth jamming processing on the dog clutch A based on the clutch tooth jamming processing strategy. The clutch tooth jamming processing strategy is a strategy to adjust clutches D and E. Clutches B, C, D and E are multi-plate clutches.

[0086] This embodiment outputs a clutch engagement command when the engine is detected to be running and the vehicle is in a fault-free state. This clutch engagement command controls the engagement of the dog clutch A. Based on the clutch engagement command, clutches B and C are depressurized, and during the depressurization process, it is detected whether the dog clutch A has reached the engagement position. If not, it is determined that the dog clutch A is jammed, and a jamming handling strategy is implemented to handle the jamming of the dog clutch A. The jamming handling strategy involves adjusting clutches D and E. Clutches B, C, D, and E are multi-plate clutches. Because this embodiment detects the state of the dog clutch A after outputting the clutch engagement command and handles the jamming of the dog clutch A based on the clutch jamming handling strategy when jamming is detected, it avoids the technical drawback of gear loss caused by the dog clutch failing to reach the expected position, thereby improving vehicle driving safety.

[0087] Based on the first embodiment of the clutch gear engagement and gear jamming treatment device of the present invention, a second embodiment of the clutch gear engagement and gear jamming treatment device of the present invention is proposed.

[0088] In this embodiment, the instruction output module 601 is further configured to, when the engine is detected to be running and the vehicle is in a fault-free state, engage the vehicle in D gear; control the rotational speed of the dog clutch A through clutch B and clutch C, and monitor the speed difference between the two ends of the dog clutch A; if the speed difference is less than a preset threshold, determine that the dog clutch A meets the engagement conditions, and output a clutch engagement command.

[0089] Furthermore, the tooth jamming processing module 603 is also used to determine that the dog clutch A is jammed if the dog clutch A has not reached the engagement position, and to determine the corresponding tooth jamming type when the dog clutch A is jammed; if the tooth jamming type is a tooth tip jamming type, then the dog clutch A is jammed based on the first clutch tooth jamming processing strategy, wherein the tooth tip jamming type includes long tooth tip long tooth type and long tooth tip short tooth type.

[0090] Furthermore, the tooth-grip processing module 603 is also used to adjust the speed difference of the dog-tooth clutch A through the clutch D and the clutch E; increase the pressure on the clutch D and decrease the pressure on the clutch E, while increasing the main oil pressure of the vehicle.

[0091] Furthermore, the tooth jamming module 603 is also used to perform tooth jamming processing on the dog tooth clutch A based on the second clutch tooth jamming processing strategy if the tooth jamming type is a spline interlock tooth jamming type.

[0092] Furthermore, the tooth-grip processing module 603 is also used to adjust the circumferential force of the dog clutch A by changing the torque of the clutch D and the clutch E; to capture the transmitted torque of the dog clutch A in real time according to the adjusted circumferential force of the dog clutch A; and to stop changing the torque of the clutch D and the clutch E when the transmitted torque is detected to be zero.

[0093] Furthermore, the clutch tooth jamming module 603 is also used to activate the main hydraulic pressure tooth jamming strategy simultaneously when the clutch tooth jamming strategy is detected to be activated. The main hydraulic pressure tooth jamming strategy is used to adjust the main hydraulic pressure of the vehicle.

The main hydraulic pressure tooth jamming treatment strategy is used to adjust the main hydraulic pressure of the vehicle.

4. A clutch engagement gear processing device, characterized in that, The clutch engagement gear handling device includes: The command output module is used to output a clutch engagement command when the engine is detected to be running and the vehicle is in a fault-free state. The clutch engagement command is used to control the dog clutch A to engage. The position detection module is used to depressurize clutches B and C according to the clutch engagement command, and to detect whether the dog clutch A has reached the engagement position during the depressurization process. The tooth jamming module is used to determine if the dog clutch A is jammed if not, and to perform tooth jamming processing on the dog clutch A based on the clutch tooth jamming processing strategy. The clutch tooth jamming processing strategy is a strategy to adjust clutches D and E. Clutches B, C, D and E are multi-plate clutches. The tooth-handling module is also used for: If the dog clutch A does not reach the engagement position, it is determined that the dog clutch A is stuck, and the type of stuck tooth is determined. If the tooth jamming type is a tooth tip jamming type, then the dog clutch A is jammed based on the first clutch jamming treatment strategy. The tooth tip jamming type includes long tooth tip long tooth type and long tooth tip short tooth type. The first clutch jamming treatment strategy includes: adjusting the speed difference of the dog clutch A through the clutch D and the clutch E; increasing the pressure on the clutch D and decreasing the pressure on the clutch E, while increasing the main hydraulic pressure of the vehicle. If the tooth type is a spline interlocking tooth type, then the dog clutch A is subjected to tooth jamming based on the second clutch tooth jamming processing strategy; the second clutch tooth jamming processing strategy includes: adjusting the circumferential force of the dog clutch A by changing the torque of the clutch D and the clutch E; capturing the transmitted torque of the dog clutch A in real time according to the adjusted circumferential force of the dog clutch A; and stopping the change of the torque of the clutch D and the clutch E when the transmitted torque is detected to be zero.
