Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically a method, device, terminal, and storage medium for handling abnormal gear separation in a multi-speed hybrid transmission. Background Technology

[0002] Currently, multi-gear hybrid transmissions are widely used in the market. By rationally setting two or more gears, the overall vehicle power and fuel economy can be improved, and they are often used in high-end models with high performance requirements. The introduction of multiple gears brings about gear selection and control issues. Unlike traditional transmissions, hybrid transmissions need to comprehensively judge gear selection based on vehicle mode requirements and system fault status. This function, as a post-processing mechanism for abnormal gear operation, is an important part of system fault detection and handling. Currently, there is no method for post-processing abnormal gear operation. Summary of the Invention

[0003] This invention proposes a method, device, terminal, and storage medium for post-processing of abnormal gear separation in a multi-speed hybrid transmission. While ensuring system safety, this function, through reasonable triggering, enables post-processing of abnormal gear separation faults in the system, thereby improving the rationality of the application and diagnosis of the shifting system.

[0004] The technical solution of this invention is described below in conjunction with the accompanying drawings:

[0005] In a first aspect, embodiments of the present invention provide a method for handling abnormal gear separation in a multi-gear hybrid dedicated transmission, including:

[0006] The functional precondition judgment module determines the preconditions for post-gear abnormal exit and gear disengagement processing, and outputs a flag indicating whether the preconditions are met in real time, which is then sent to the gear abnormal separation detection module.

[0007] When the preconditions are met, the gear shift abnormality detection module, in conjunction with the G1BlockOut, G1JumpOut, G2BlockOut, and G2JumpOut signals output by the diagnostic module, performs gear shift abnormality status detection and reset, and outputs a flag indicating whether gear shift abnormality has occurred in 1st or 2nd gear in real time. When G1Out = 1 or G2Out = 1, it indicates that gear shift abnormality has occurred in 1st or 2nd gear. When G1Out = 0 and G2Out = 0, it indicates that the gear shift abnormality flag for 1st or 2nd gear has been reset. The G1Out and G2Out flags are output to the target N-gear arbitration module in real time, and, in conjunction with the VCU request for target gear and the VCU communication fault signal output by the vehicle control module, jointly make a decision and output the requested gear.

[0008] The gear execution and post-processing module receives the gear request output from the target N gear arbitration module in real time, and, in conjunction with other forced gear requests and the overall vehicle status, reasonably triggers the prohibition of parallel operation and the supplementary disengagement of gears.

[0009] Furthermore, the specific working method of the functional precondition judgment module for handling preconditions after judging abnormal gear position and exiting to re-engage is as follows:

[0010] A1. The system has no definite gear abnormality fault;

[0011] B1. The hydraulic system has no leakage faults;

[0012] C1. All sensors related to gear shifting are functioning correctly;

[0013] D1. All actuators related to gear shifting are functioning correctly;

[0014] E1. Main oil circuit pressure build-up is normal;

[0015] Among them, when A1, B1, C1, D1, and E1 are all satisfied, it is determined that the preconditions for handling the abnormal gear exit and subsequent gear disengagement are met.

[0016] Furthermore, the specific working method of the gear abnormal separation detection module for detecting and resetting the gear abnormal separation state is as follows:

[0017] A2. Upon receiving the first gear cannot be engaged (G1BlockOut flag), the first gear abnormal disengagement flag G1Out=1 is set, and a timer is started. If the set time T_BlockOutResetHld is exceeded, the gear disengagement action is performed for the set duration. Alternatively, upon receiving the first gear disengagement flag, the first gear abnormal disengagement flag G1Out=0 is cleared.

[0018] B2. Upon receiving the 1st gear unexpected jump (G1JumpOut flag), the 1st gear abnormal separation flag G1Out = 1, and a timer starts; if the set time T_JumpOutResetHld is exceeded, the set duration of the re-gear disengagement action is executed, or upon receiving the 1st gear separation flag, the 1st gear abnormal separation flag G1Out = 0 is cleared.

[0019] C2. Upon receiving the G2BlockOut flag indicating that 2nd gear cannot be engaged, the 2nd gear abnormal disengagement flag G2Out=1 is set, and a timer is started. If the set time T_BlockOutResetHld is exceeded, the set duration of the disengagement action is executed, or if the 2nd gear disengagement flag is received, the 2nd gear abnormal disengagement flag G2Out=0 is cleared.

[0020] D2. Upon receiving the 2nd gear unexpected jump (G2JumpOut) flag, the 2nd gear abnormal separation flag G2Out=1, and a timer starts; if the set time T_JumpOutResetHld is exceeded, the set duration of the re-gear disengagement action is executed, or if the 2nd gear separation flag is received, the 2nd gear abnormal separation flag G2Out=0 is cleared.

[0021] Furthermore, the specific working method of the target N-gear arbitration module and the target gear output N activation condition judgment submodule is as follows:

[0022] A3. Input gear availability status is N gear available;

[0023] B3, VCU input target gear request is 1st gear, but the 1st gear abnormal separation flag is 1;

[0024] C3 and VCU input target gear request is 2nd gear, but the 2nd gear abnormal separation flag is 1;

[0025] D3. Communication failure of the upper-level controller;

[0026] When A3&&(B3||C3||D3), the target gear is N gear, and bCond_Neutral=1 is activated.

[0027] Furthermore, the specific working method of the target N-gear arbitration module and the target gear output N activation condition judgment submodule is as follows:

[0028] A4. Input gear availability status is N gear unavailable;

[0029] B4. Input gear availability status is N gear available, upper controller communication is normal, VCU input target gear request is 1 gear, 1 gear abnormal separation flag bit is restored to 0;

[0030] C4. Input gear availability status is N gear available, upper controller communication is normal, VCU input target gear request is 2nd gear, 2nd gear abnormal separation flag bit is restored to 0;

[0031] D4. Input gear availability status is N gear available, upper controller communication is normal, VCU input target gear request is N gear;

[0032] When A4||B4||C4||D4, the target gear is forcibly exited as N bCond_Neutral=0.

[0033] Furthermore, the specific working method of the gear shifting and post-processing module is as follows:

[0034] A5. Parallel Mode Prohibition: After an abnormal gear state is triggered, G1Out == 1 or G2Out == 1, output a gear shifting / disengagement flag for a specific duration T_GearRetrying: GearRetrying = 1; when GearRetrying == 1, it is considered that the system is in the process of shifting / disengaging, and a clutch disengagement request is sent to the VCU to prohibit the system from entering parallel mode. At the same time, the corresponding actuators are triggered to ensure the power source for shifting / disengaging the system.

[0035] B5. Execute the gear shift disengagement action: If condition 1 is met, when bCond_Neutral == 1, the output gear request is N gear, and the gear shift disengagement action is executed. If bCond_Neutral == 0, the VCU gear request is responded to. If the request is 1st or 2nd gear, normal gear engagement is performed; if the request is N gear, N gear is temporarily maintained. If, under the premise of meeting condition 1, an abnormal downshift or inability to engage occurs again during gear engagement, then as described in 2, bCond_Neutral == 1, the gear request is N gear, and the gear shift disengagement action is executed; this process is repeated until gear engagement is successful, or if gear engagement still fails after a set number of attempts, the corresponding gear fault is confirmed and output.

[0036] A5 and B5 are executed simultaneously.

[0037] Furthermore, the duration of T_GearRetrying needs to cover the expected number of gear re-engagement and re-engagement attempts, and should be set to several times the duration of T_BlockOutResetHld and T_JumpOutResetHld.

[0038] Secondly, embodiments of the present invention also provide a post-processing device for abnormal gear separation of a multi-speed hybrid dedicated transmission, comprising:

[0039] The functional precondition judgment module is used to judge the preconditions for the post-gear abnormal exit and re-gear disengagement processing, and output the flag of whether the preconditions are met in real time, which is then sent to the gear abnormal separation detection module.

[0040] The gear shift anomaly detection module, when the given conditions are met, combines the G1BlockOut, G1JumpOut, G2BlockOut, and G2JumpOut signals output by the diagnostic module to detect and reset the gear shift anomaly status, and outputs a flag indicating whether gear shift anomaly has occurred in 1st or 2nd gear in real time; when G1Out = 1 or G2Out = 1, it indicates that gear shift anomaly has occurred in 1st or 2nd gear; when G1Out = 0 and G2Out = 0, it indicates that the gear shift anomaly flag for 1st or 2nd gear has been reset to zero; the G1Out and G2Out flags are output to the target N-gear arbitration module in real time;

[0041] The target N-gear arbitration module is used to combine the VCU request for the target gear output by the vehicle control module and the VCU communication fault signal to make a joint decision and output the requested gear.

[0042] The gear execution and post-processing module is used to receive the gear request output from the target N gear arbitration module in real time, and, in combination with other forced gear requests and the overall vehicle status, reasonably trigger the prohibition of parallel operation and the supplementary disengagement execution.

[0043] Thirdly, a terminal is provided, including:

[0044] One or more processors;

[0049] Fifthly, an application product is provided, which, when running on a terminal, causes the terminal to execute the method described in the first aspect of the present invention.

[0050] The beneficial effects of this invention are as follows:

[0051] This invention is based on the judgment and processing of abnormal gear disengagement state of the system, the judgment of the current gear availability state, and the target gear input signal, etc., and comprehensively judges and outputs a signal to force the target gear to N gear. It realizes the output of multiple gear disengagement requests under abnormal gear state, and designs a countermeasure. When performing gear disengagement in abnormal gear disengagement state of the system, it interacts with the vehicle controller to request the disengagement of the clutch to avoid derivative faults.

[0062] Example 1

[0063] Figure 1 , Figure 2 , Figure 3 and Figure 4 This is a schematic diagram of a multi-speed hybrid system configuration and its operating mode. This invention is applicable to all multi-speed hybrid transmissions with the configuration shown in the diagram. The multi-speed hybrid transmission-specific decision-making method for forcibly shifting to neutral (N) in this invention outputs a forced shift signal to N gear via a decision module, which serves as the actual shift execution request. There are no requirements regarding the form of the actual shift execution mechanism (such as electric, hydraulic, or pneumatic actuation).

[0064] See Figure 5This embodiment provides a method for handling abnormal gear separation in a 2-speed hybrid dedicated transmission. This method can be executed by a device for handling abnormal gear separation in a multi-speed hybrid dedicated transmission, as described in this embodiment. This device can be implemented in software and / or hardware, and specifically consists of the following parts:

[0065] I. The precondition judgment module determines the preconditions for handling gear abnormality exit and gear disengagement, and outputs a flag indicating whether the preconditions are met in real time, which is then sent to the gear abnormality separation detection module, as detailed below:

[0066] A1. The system has no definite gear abnormality fault;

[0067] B1. The hydraulic system has no leakage faults;

[0068] C1. All sensors related to gear shifting are functioning correctly (related to the design of the shifting system, such as the shift fork position sensor and the main oil circuit pressure sensor).

[0069] D1. All actuators related to gear shifting are functioning properly; (This is related to the design of the actuator system. For example, if it is a hydraulic gear shifting system, it should include relevant solenoid valves, mechanical valves, etc.)

[0070] E1. Main oil circuit pressure build-up is normal (if it is a hydraulic shifting system).

[0071] Among them, when A1, B1, C1, D1, and E1 are all satisfied, it is determined that the preconditions for handling the abnormal gear exit and subsequent gear disengagement are met.

[0072] II. When the current conditions are met, the gear shift abnormality detection module, in conjunction with the G1BlockOut, G1JumpOut, G2BlockOut, and G2JumpOut signals output by the diagnostic module, performs gear shift abnormality status detection and reset, and outputs a flag indicating whether gear shift abnormality has occurred in 1st or 2nd gear in real time; when G1Out = 1 or G2Out = 1, it indicates that gear shift abnormality has occurred in 1st or 2nd gear; when G1Out = 0 and G2Out = 0, it indicates that the gear shift abnormality flag for 1st or 2nd gear has been reset to zero; the G1Out and G2Out flags are output to the target N-gear arbitration module in real time; as detailed below:

[0073] A2. Upon receiving the first gear cannot be engaged (G1BlockOut flag), the first gear abnormal disengagement flag G1Out=1 is set, and a timer is started. If the set time T_BlockOutResetHld is exceeded, the gear disengagement action is performed for the set duration. Alternatively, upon receiving the first gear disengagement flag, the first gear abnormal disengagement flag G1Out=0 is cleared.

[0074] B2. Upon receiving the 1st gear unexpected jump (G1JumpOut flag), the 1st gear abnormal separation flag G1Out = 1, and a timer starts. If the set time T_JumpOutResetHld is exceeded, a gear replacement action is performed for the set duration; or upon receiving the 1st gear separation flag, the 1st gear abnormal separation flag G1Out = 0 is cleared.

[0075] C2. Upon receiving the G2BlockOut flag indicating that 2nd gear cannot be engaged, the 2nd gear abnormal disengagement flag G2Out=1 is set, and a timer is started. If the set time T_BlockOutResetHld is exceeded, the set duration of the disengagement action is executed, or if the 2nd gear disengagement flag is received, the 2nd gear abnormal disengagement flag G2Out=0 is cleared.

[0076] D2. Upon receiving the 2nd gear unexpected jump (G2JumpOut) flag, the 2nd gear abnormal separation flag G2Out=1, and a timer starts; if the set time T_JumpOutResetHld is exceeded, the set duration of the re-gear disengagement action is executed, or if the 2nd gear separation flag is received, the 2nd gear abnormal separation flag G2Out=0 is cleared.

[0077] Third, the target N-gear arbitration module, in conjunction with the VCU request for the target gear output by the vehicle control module and the VCU communication fault signal, jointly decides and outputs the requested gear; the target N-gear arbitration module includes a target gear output N activation condition judgment submodule and a target gear N deactivation condition judgment submodule, as detailed below:

[0078] The working principle of the target gear output N activation condition judgment submodule is as follows:

[0079] A3. Input gear availability status is N gear available;

[0080] B3, VCU input target gear request is 1st gear, but the 1st gear abnormal separation flag is 1;

[0081] C3 and VCU input target gear request is 2nd gear, but the 2nd gear abnormal separation flag is 1;

[0082] D3. Communication failure of the upper-level controller;

[0083] When A3&&(B3||C3||D3), the target gear is N gear, and bCond_Neutral=1 is activated.

[0084] The working principle of the target gear N deactivation condition judgment submodule is as follows:

[0085] A4. Input gear availability status is N gear unavailable;

[0086] B4. Input gear availability status is N gear available, upper controller communication is normal, VCU input target gear request is 1 gear, 1 gear abnormal separation flag bit is restored to 0;

[0087] C4. Input gear availability status is N gear available, upper controller communication is normal, VCU input target gear request is 2nd gear, 2nd gear abnormal separation flag bit is restored to 0;

[0088] D4. The input gear availability status is N gear available, the upper-level controller communication is normal, and the VCU input target gear request is N gear.

[0089] When A4||B4||C4||D4, the target gear is forcibly exited as N bCond_Neutral=0.

[0090] IV. Gear Execution and Post-processing Module: This module receives gear requests from the target N-gear arbitration module in real time, and, considering other forced gear requests and the overall vehicle status, appropriately triggers parallel gear disengagement and de-gear replacement execution, as detailed below:

[0091] A5. Parallel Mode Prohibition: After an abnormal gear state is triggered, G1Out == 1 or G2Out == 1, output a gear re-engagement / disengagement flag for a specific duration T_GearRetrying: GearRetrying = 1; when GearRetrying == 1, it is considered that the system is in the process of re-engaging / disengaging gears, and a clutch disengagement request is sent to the VCU to prohibit the system from entering parallel mode. At the same time, the response execution unit is triggered to ensure the power source for the system's re-engagement / disengagement gears.

[0092] B5. Execute the gear shift disengagement action: If condition 1 is met, when bCond_Neutral == 1, the output gear request is N gear, and the gear shift disengagement action is executed. If bCond_Neutral == 0, the VCU gear request is responded to. If the request is 1st or 2nd gear, normal gear engagement is performed; if the request is N gear, N gear is temporarily maintained. If, under the premise of meeting condition 1, an abnormal downshift or inability to engage occurs again during gear engagement, then as described in 2, bCond_Neutral == 1, the gear request is N gear, and the gear shift disengagement action is executed; this process is repeated until gear engagement is successful, or if gear engagement still fails after a set number of attempts, the corresponding gear fault is confirmed and output.

[0093] A5 and B5 are executed simultaneously.

[0094] Furthermore, the duration of T_GearRetrying needs to cover the expected number of gear re-engagement and re-engagement attempts, and should be set to several times the duration of T_BlockOutResetHld and T_JumpOutResetHld.

[0095] In summary, this invention, based on the judgment and processing of abnormal gear disengagement state of the system, the judgment of the current gear availability state, and the target gear input signal, comprehensively judges and outputs a signal to force the target gear to N gear, realizes the output of multiple gear disengagement requests under abnormal gear state, and designs a countermeasure. When performing gear disengagement in abnormal gear disengagement state of the system, it interacts with the vehicle controller to request the disengagement of the clutch, so as to avoid derivative faults.

[0096] It should be noted that the above embodiments describe a method for handling abnormal gear separation in a 2-speed hybrid system. In fact, the method for handling abnormal gear separation in a multi-speed hybrid system can also be carried out in accordance with the method described in this invention, within the scope of protection of this invention.

[0097] Example 2

[0098] See Figure 6 This embodiment provides a post-processing device for abnormal gear separation in a multi-speed hybrid dedicated transmission, comprising:

[0100] The gear shift anomaly detection module is used to detect and reset the gear shift anomaly status when the given conditions are met, based on the G1BlockOut, G1JumpOut, G2BlockOut, and G2JumpOut signals output by the diagnostic module. It outputs a real-time flag indicating whether gear shift anomaly has occurred in 1st or 2nd gear. When G1Out = 1 or G2Out = 1, it indicates that gear shift anomaly has occurred in 1st or 2nd gear. When G1Out = 0 and G2Out = 0, it indicates that the gear shift anomaly flag for 1st or 2nd gear has been reset. The G1Out and G2Out flags are output to the target N-gear arbitration module in real-time.

[0101] The target N-gear arbitration module is used to combine the VCU request for the target gear output by the vehicle control module and the VCU communication fault signal to make a joint decision and output the requested gear.

[0102] The gear execution and post-processing module is used to receive the gear request output by the target N gear arbitration module in real time, and, in combination with other forced gear requests and the overall vehicle status, reasonably trigger the prohibition of parallel operation and the supplementary disengagement execution.

Claims

1. A method for handling abnormal gear disengagement in a multi-speed hybrid dedicated transmission, characterized in that, include: The functional precondition judgment module determines the preconditions for post-gear abnormal exit and gear disengagement processing, and outputs a flag indicating whether the preconditions are met in real time, which is then sent to the gear abnormal separation detection module. When the preconditions are met, the gear shift anomaly detection module, in conjunction with the diagnostic module's output signals (G1BlockOut, G1JumpOut, G2BlockOut, G2JumpOut), performs gear shift anomaly detection and reset, and outputs a real-time flag indicating whether gear shift anomaly has occurred in 1st or 2nd gear. When G1Out=1 or G2Out=1, it indicates that gear shift anomaly has occurred in 1st or 2nd gear; when G1Out=0 and G2Out=0, it indicates that the gear shift anomaly flag has been reset. The G1Out and G2Out flags are output in real-time to the target N-gear arbitration module, which, in conjunction with the VCU request for the target gear and the VCU communication fault signal output by the vehicle control module, jointly makes a decision and outputs the requested gear. The gear execution and post-processing module receives the gear request output from the target N gear arbitration module in real time, and, in conjunction with other forced gear requests and the overall vehicle status, reasonably triggers the prohibition of parallel operation and the supplementary disengagement execution; The specific working method of the gear shifting and post-processing module is as follows: A5. Parallel Mode Prohibition: After an abnormal gear state is triggered, G1Out==1 or G2Out==1, output a gear re-engagement / disengagement flag for a specific duration T_GearRetrying: GearRetrying=1; when GearRetrying==1, it is considered that the system is in the process of re-engaging / disengaging gears, and a clutch disengagement request is sent to the VCU to prohibit the system from entering parallel mode. At the same time, the response execution unit is triggered to ensure the power source for the system's re-engagement / disengagement gears. B5. Execute the gear shifting action: If condition 1 is met, when bCond_Neutral == 1, the output gear request is N gear, and the gear shifting action is executed. If bCond_Neutral == 0, the VCU gear request is responded to. If the request is 1st or 2nd gear, normal gear engagement is performed. If N gear is requested, N gear is temporarily maintained. If, under the premise of meeting condition 1, an abnormal downshift or inability to engage occurs again during gear engagement, then bCond_Neutral == 1, the gear request is N gear, and the gear shifting action is executed. This process is repeated until gear engagement is successful, or if gear engagement still fails after a set number of attempts, the corresponding gear fault is confirmed and output. A5 and B5 are executed simultaneously.
