Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, and more particularly to a method and device for identifying an automatic gear shifting process, an electronic device and a storage medium. BACKGROUND

[0002] AMT (Automated Mechanical Transmission) is also known as an automatic manual transmission. It is an automatic transmission system with a microcomputer control installed on the basis of a dry clutch and a gear transmission. The AMT transmission is a combination of the advantages of automatic and manual transmissions, and is an automatic transmission integrating mechanical, electrical and hydraulic systems. It has the advantages of automatic transmission, and also has the advantages of high efficiency, low cost, simple structure and easy manufacturing of the original manual transmission.

[0003] The gear shifting process of the AMT transmission includes three stages of clearing torque, synchronization and returning torque. In the clearing torque process, the engine torque gradually decreases to 0, and in this process, the clutch of the transmission gradually separates. In the synchronization process, the engine speed is adjusted to the speed required by the transmission to facilitate gear shifting. In the returning torque stage, the actual torque of the engine gradually increases to meet the demand torque of the transmission, and the returning torque process is completed when the actual torque reaches the demand torque, thus completing the gear shifting process.

[0004] To meet the demand for driving comfort, the engine needs to take special control strategies for torque, throttle, supercharger, EGR, etc. in different gear shifting stages during the gear shifting process of the AMT transmission. However, for vehicles with natural gas engines, it is more difficult to control due to its relatively slow speed compared to diesel engines. Therefore, the current control strategy for vehicles with natural gas engines does not identify the clearing torque-synchronization-returning torque process of the AMT gear shifting, which makes it impossible to take appropriate control strategies for the gear shifting process and meet the demand for driving comfort. SUMMARY

[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of the present application.

[0058] The present application provides an intelligent recognition scheme for an automatic shifting process of a natural gas engine adapted to an AMT gearbox. In the automatic shifting process of a vehicle equipped with an AMT automatic gearbox, the natural gas engine needs to complete torque zeroing and torque recovery in a very short time, and respond to the control from the gearbox to complete the automatic shifting process. If the engine cannot well follow the control requirements of the gearbox, it will seriously affect the shifting comfort and the driving experience. For the natural gas engine, through the vehicle experiments of the inventor, it is found that if the control strategy used in the normal steady state is adopted, the engine cannot meet the control response requirements in the shifting process. In order to make up for this defect, the present application recognizes the torque zeroing-synchronization-torque recovery process of the AMT gearbox in the shifting process, so as to take targeted ECU control strategy to speed up the engine response speed in each stage and improve the driving comfort. Based on this, the following technical solutions are proposed.

[0059] Figure 1 A flow chart of an automatic shifting process recognition method according to an embodiment of the present application.

[0060] As Figure 1As shown, the embodiment provides a recognition method of automatic gear shifting process, which is applied to an electronic device of a vehicle, the vehicle is provided with a natural gas engine and an AMT gearbox, and is used for recognizing the automatic gear shifting process of the AMT gearbox. The electronic device can be a server, a PC, a PAD, a mobile phone, an ECU (Electronic Control Unit), a VCU (Vehicle Control Unit), an MCU (Micro Controller Unit), an HCU (Hybrid Control Unit) and the like which have data processing ability and information processing ability. The specific recognition process is as follows:

[0061] S1, judging whether the engine control mode message can be received.

[0062] The message is from the TCU of the AMT gearbox, if the message can be received, the gear shifting process can be recognized based on the message and other parameters, and the subsequent step S2 is executed; if the message cannot be received due to the disconnection of the bus, the gear shifting process is recognized according to the clutch state of the AMT gearbox, i.e. whether the gears of the clutch are engaged and other parameters, and the step S4 is executed.

[0063] S2, judging whether the opening degree of the accelerator pedal of the vehicle is greater than a first opening degree threshold.

[0064] It is actually judged whether the signal sent by the accelerator pedal represents that the opening degree of the accelerator pedal is greater than the first opening degree threshold, the threshold is determined through bench test or experience, and can be a value close to 0. If it is less than or equal to the first opening degree threshold, it indicates that the driver does not step on the pedal, at this time, it is in the power-off gear shifting process, and is not recognized; otherwise, if it is greater than the first opening degree threshold, the subsequent recognition step is executed.

[0065] S3, recognizing the gear shifting process according to the engine control mode and other parameters.

[0066] The application is implemented according to the engine control mode of the natural gas engine and other parameters, the engine control mode is obtained from the TCU (Transmission Control Unit) of the AMT gearbox through the bus, and the other parameters include the target gear position, the actual gear position, the actual torque, the demand torque and the gear shifting process state of the AMT gearbox. The specific recognition method is as follows:

[0067] When the engine control mode is the clean twist stage engine control mode, the target gear position is not equal to the actual gear position, the target gear position changes, the actual gear position and the target gear position are both not the neutral gear position, and the shift process state quantity is the active state, the current shift process is identified as the clean twist stage.

[0068] When the engine control mode is the synchronization stage engine control mode, the actual gear position and the target gear position are both not the neutral gear position, and the shift process state quantity is the active state, the current shift process is identified as the synchronization stage.

[0069] When the engine control mode, the actual gear position, the target gear position, the demand torque, the actual torque and the shift process state quantity all satisfy the shift twist judgment condition, the current shift process is identified as the shift twist stage, and the shift twist stage includes the entering shift twist process and the shift twist process end.

[0070] Specifically, the identification of the shift twist stage is realized by the following means, that is, determining whether the shift twist stage is in the entering shift twist process or the shift twist process end.

[0071] When the engine control mode is the shift twist stage engine control mode, the actual gear position and the target gear position are both not the neutral gear position, and the shift process state quantity is the active state, the current shift process is identified as the entering shift process. When the change rate of the demand torque is stable, if the actual torque and the demand torque are in the close range or the actual gear position is the neutral gear position or the target gear position is the neutral gear position, the current shift process is identified as the shift twist process end.

[0072] S4, judging whether the accelerator pedal opening degree of the vehicle is greater than a second opening degree threshold.

[0073] In fact, it is to judge whether the signal sent by the accelerator pedal represents that the opening degree of the accelerator pedal is greater than the second opening degree threshold, which is determined by bench test or experience and can be a value close to 0. If it is less than or equal to the second opening degree threshold, it indicates that the driver does not step on the pedal, at this time, the power-off shift process is in the process, and it is not identified; otherwise, if it is greater than the second opening degree threshold, the subsequent identification steps are executed. The second opening degree threshold and the first opening degree threshold can be the same or different.

[0074] S5, identifying the shift process according to the clutch state and other multiple parameters.

[0075] The application is to judge according to the clutch state and other multiple parameters of the AMT gearbox, the clutch state includes the meshing state and the non-meshing state, and the other multiple parameters include the target gear position, the actual gear position, the actual torque, the demand torque and the shift process state of the AMT gearbox. The specific identification method is as follows:

[0076] When the clutch state is the engaged state, the target gear position is not equal to the actual gear position, the target gear position changes, the actual gear position and the target gear position are both not the neutral gear position, and the gear shifting process state quantity is the activated state, the current gear shifting process is identified as the twist cleaning stage.

[0077] When the clutch state is the disengaged state, the actual gear position is not equal to the target gear position, the actual gear position and the target gear position are both not the neutral gear position, the gear shifting process state quantity is the activated state, the required torque is less than the first threshold value, and the change rate of the required torque is less than the second threshold value, the current gear shifting process is identified as the synchronization stage.

[0078] When the actual gear position, the target gear position, the required torque, the actual torque, and the gear shifting process state quantity all satisfy the twist shifting judgment condition, the current gear shifting process is identified as the twist returning stage, and the twist returning stage includes the entering twist shifting process and the twist shifting process end.

[0079] Specifically, the identification of the twist shifting stage is realized by the following means, that is, determining whether the twist returning stage is in the entering twist shifting process or the twist shifting process end.

[0080] When the change rate of the required torque is greater than the third threshold value, the actual gear position and the target gear position are both not the neutral gear position, the actual gear position is equal to the target gear position, and the gear shifting process state quantity is the activated state, the current gear shifting process is identified as the entering gear shifting process; when the change rate of the required torque is stable, if the actual torque and the required torque are in the close range, the actual gear position is the neutral gear position, or the target gear position is the neutral gear position, the current gear shifting process is identified as the twist shifting process end.

[0081] It can be seen from the above technical solution that the embodiment provides an identification method of an automatic gear shifting process. The method is applied to an electronic device of a vehicle, specifically, whether an engine control mode message of an AMT gearbox can be received is judged; if the engine control mode message can be received, whether the opening degree of an accelerator pedal of the vehicle is greater than a first opening degree threshold value is judged; if the opening degree is greater than the first opening degree threshold value, whether the current gear shifting process of the AMT gearbox is identified based on whether the engine control mode of a natural gas engine, a target gear position, an actual gear position, an actual torque, a required torque, and a gear shifting process state are activated is judged; if the engine control mode message cannot be received, whether the opening degree of the accelerator pedal is greater than a second opening degree threshold value is judged; if the opening degree is greater than the second opening degree threshold value, whether the current gear shifting process of the AMT gearbox is identified based on whether the clutch state of the AMT engine, the target gear position, the actual gear position, the actual torque, the required torque, and the gear shifting process state are activated is judged. Through the identification of the current gear shifting process, appropriate control strategies can be adopted for the gear shifting process, so as to meet the demand for driving comfort.

[0082] The computer program instructions can also be loaded onto a computer or other programmable information processing apparatus to cause a series of operations to be performed on the computer or other programmable information processing apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable information processing apparatus implement the functions / acts specified in the flowchart and / or block diagram block or blocks.

[0086] Figure 2 A flowchart for an identification of an automatic gear shift process according to an embodiment of the present application.

[0087] As Figure 2As shown, the embodiment provides a recognition device of automatic gear shifting process, which is applied to an electronic device of a vehicle, the vehicle is provided with a natural gas engine and an AMT gearbox, and is used for recognizing the automatic gear shifting process of the AMT gearbox. The electronic device can be a server, a PC, a PAD, a mobile phone, an ECU (Electronic Control Unit), a VCU (Vehicle Control Unit), an MCU (Micro Controller Unit), an HCU (Hybrid Control Unit) and the like which have data processing ability and information processing ability. The recognition device comprises a first judging module 10, a second judging module 20, a first recognition module 30, a third judging module 40 and a second recognition module 50.

[0088] The first judging module is used for judging whether the engine control mode message of the AMT gearbox can be received.

[0089] The second judging module is used for further judging whether the opening degree of the accelerator pedal of the vehicle is greater than a first opening threshold value if the engine mode message can be received.

[0090] In fact, it is judged whether the signal sent by the accelerator pedal represents whether the opening degree of the accelerator pedal is greater than the first opening threshold value, and the threshold value is determined through a bench test or experience and can be a value close to 0. If it is less than or equal to the first opening threshold value, it indicates that the driver does not step on the pedal, at this time, the no-power gear shifting process is not recognized.

[0091] The first recognition module is used for recognizing the gear shifting process according to the engine control mode and other parameters if the opening degree of the accelerator pedal is greater than the first opening threshold value.

[0092] The application is implemented according to the engine control mode of the natural gas engine and other parameters, the engine control mode is obtained from the TCU (Transmission Control Unit) of the AMT gearbox through a bus, and the other parameters include the target gear position, the actual gear position, the actual torque, the required torque and the gear shifting process state of the AMT gearbox. The module comprises a first recognition unit, a second recognition unit and a third recognition unit.

[0093] When the engine control mode is the engine control mode in the clear torque stage, the target gear position is not equal to the actual gear position, the target gear position changes, the actual gear position and the target gear position are both not the neutral gear, and the gear shifting process state is the active state, the first recognition unit recognizes the current gear shifting process as the clear torque stage.

[0094] When the engine control mode is the synchronization stage engine control mode, and the actual gear and the target gear are both non-empty gears, and the shift process state quantity is the active state, the second identification unit identifies the current shift process as a synchronization stage.

[0095] When the engine control mode, the actual gear, the target gear, the demand torque, the actual torque, and the shift process state quantity all satisfy the torque shift judgment condition, the third identification unit identifies the current shift process as a torque shift stage, which includes an entering torque shift process and a torque shift process end.

[0096] Specifically, the third identification unit identifies the torque shift stage by determining whether the torque shift stage is in the entering torque shift process or the torque shift process end.

[0097] When the engine control mode is the torque shift stage engine control mode, and the actual gear and the target gear are both non-empty gears, and the shift process state quantity is the active state, the current shift process is identified as an entering shift process; when the change rate of the demand torque is stable, if the actual torque and the demand torque are in the proximity range, or the actual gear is a non-empty gear, or the target gear is a non-empty gear, the current shift process is identified as a torque shift process end.

[0098] The third judgment module is configured to further judge whether the accelerator pedal opening degree of the vehicle is greater than a second opening degree threshold if the engine mode message cannot be received.

[0099] In fact, it is to judge whether the signal sent by the accelerator pedal represents that the opening degree of the accelerator pedal is greater than the second opening degree threshold, which is determined through bench testing or experience and can be a value close to 0. If it is less than or equal to the second opening degree threshold, it indicates that the driver does not step on the pedal, at which time the power-off shift process is not identified. The second opening degree threshold and the first opening degree threshold can be the same or different.

[0100] The second identification module is configured to identify the shift process according to the clutch state and other parameters when the accelerator pedal opening degree is greater than the second opening degree threshold.

[0101] The application is implemented according to the clutch state and other parameters of the AMT gearbox to make a judgment, the clutch state includes the engaged state and the disengaged state, and the other parameters include the target gear, the actual gear, the actual torque, the demand torque, and the shift process state of the AMT gearbox. The second identification module includes a fourth identification unit, a fifth identification unit, and a sixth identification unit.

[0102] When the clutch state is the engaged state, the target gear is not equal to the actual gear, the target gear changes, the actual gear and the target gear are both non-empty gears, and the shift process state quantity is the active state, the fourth identification unit identifies the current shift process as a torque shift stage;

[0103] When the clutch state is the disengaged state, the actual gear position is not equal to the target gear position, the actual gear position and the target gear position are not the neutral gear position, the gear shifting process state quantity is the activated state, the demand torque is less than the first threshold value, and the change rate of the demand torque is less than the second threshold value, the fifth identification unit identifies the current gear shifting process as the synchronization stage.

[0104] When the actual gear position, the target gear position, the demand torque, the actual torque, and the gear shifting process state quantity all satisfy the torque shifting judgment condition, the sixth identification unit identifies the current gear shifting process as the torque shifting stage, and the torque shifting stage includes the entering torque shifting process and the torque shifting process end.

[0105] Specifically, the sixth identification unit identifies the torque shifting stage by determining whether the torque shifting stage is in the entering torque shifting process or the torque shifting process end.

[0106] When the change rate of the demand torque is greater than the third threshold value, the actual gear position and the target gear position are not the neutral gear position, the actual gear position is equal to the target gear position, and the gear shifting process state quantity is the activated state, the current gear shifting process is identified as the entering gear shifting process. When the change rate of the demand torque is stable, if the actual torque and the demand torque are in the close range, or the actual gear position is the neutral gear position, or the target gear position is the neutral gear position, the current gear shifting process is identified as the torque shifting process end.

[0107] As can be seen from the above technical solutions, the embodiment provides an automatic gear shifting process identification device.
