Technical Field

[0001] The present invention belongs to the field of automobile technology, and in particular to a method, device, terminal and storage medium for post-processing abnormal gear separation of a multi-speed hybrid transmission. Background Art

[0002] Among the common hybrid transmissions on the market, the hybrid multi-speed scheme is widely used. By reasonably setting two or more gears, the power and economy of the vehicle can be improved. It is mostly used in high-end models with high requirements for vehicle performance. The introduction of multiple gears brings about gear decision-making and control issues. Unlike traditional transmissions, the gear decision of hybrid transmissions also needs to be comprehensively judged in combination with the vehicle mode requirements and system fault status. This function is an important part of system fault detection and processing as a post-processing of abnormal system gear action. There is currently no post-processing method for abnormal system gear action. Summary of the invention

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

[0006] Through the function prerequisite judgment module, the gear abnormal exit and re-shift post-processing prerequisite is judged, and the flag bit of whether the prerequisite is satisfied is output in real time to the gear abnormal separation detection module;

[0007] When the prerequisite is met, the gear abnormal separation detection module, combined with the G1BlockOut, G1JumpOut, G2BlockOut, and G2JumpOut signals output by the diagnosis module, performs gear abnormal separation state detection and clearing, and outputs in real time whether the gear 1 and 2 have abnormal gear separation state flags; when G1Out=1 or G2Out=1, it means that the gear 1 or 2 is abnormally separated; when G1Out=0 and G2Out=0, it means that the gear 1 and 2 are abnormally separated. The flags of G1Out and G2Out are output to the target N gear arbitration module in real time, combined with the VCU request target gear and VCU communication fault signals output by the vehicle control module, make a joint decision, and output the requested gear;

[0008] The gear execution and post-processing module receives the requested gear output by the target N gear arbitration module in real time, and reasonably triggers the execution of parallel prohibition and supplementary gear removal based on other mandatory gear requests and vehicle status.

[0009] Furthermore, the specific working method of the function prerequisite judgment module for judging the gear abnormal exit and the post-processing prerequisite of the gear shift is as follows:

[0015] Among them, when A1, B1, C1, D1, and E1 are all met, it is determined that the prerequisite for post-processing of abnormal gear exit and gear shifting is met.

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

[0017] A2. Receive the 1st gear cannot be engaged, i.e., G1BlockOut flag, the 1st gear abnormal separation flag G1Out=1, and start timing; when the set time T_BlockOutResetHld is exceeded, the supplementary gear action setting time is executed, or receive the 1st gear separation flag, the 1st gear abnormal separation flag is cleared G1Out=0;

[0018] B2. Receive the 1st gear unexpected jump out G1JumpOut flag, the 1st gear abnormal separation flag G1Out = 1, and start timing; when the set time T_JumpOutResetHld is exceeded, the supplementary gear action setting time is executed, or receive the 1st gear separation flag, the 1st gear abnormal separation flag is cleared G1Out = 0;

[0019] C2. Receive the 2nd gear cannot be engaged, i.e., G2BlockOut flag, the 2nd gear abnormal separation flag G2Out=1, and start timing; when the set time T_BlockOutResetHld is exceeded, the gear-shifting action setting time is executed, or receive the 2nd gear separation flag, the 2nd gear abnormal separation flag is cleared G2Out=0;

[0020] D2. Receive the 2nd gear unexpected jump (G2JumpOut) flag, the 2nd gear abnormal separation flag G2Out=1, and start timing; when the set time T_JumpOutResetHld is exceeded, the gear-switching action setting duration is executed, or receive the 2nd gear separation flag, the 2nd gear abnormal separation flag is cleared G2Out=0.

[0021] Furthermore, the specific working methods of the target gear output N activation condition judgment submodule of the target gear arbitration module are as follows:

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

[0025] D3, communication failure of upper controller;

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

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

[0034] A5. Forbidden to parallel connection: After the abnormal state of gear is triggered, G1Out==1 or G2Out==1, the gear re-engagement flag of a specific duration T_GearRetrying is output: GearRetrying=1; when GearRetrying==1, it is considered that the system is re-engaging the gear, and a clutch separation request is sent to the VCU, prohibiting the system from entering the parallel connection mode, and triggering the corresponding execution components at the same time to ensure the power source of the system re-engagement;

[0035] B5. Execute the action of supplementary gear shifting: When condition 1 is met, when bCond_Neutral==1, the output gear request is N gear, and the gear shifting action is executed. When bCond_Neutral==0, respond to the VCU gear request. If the request is 1st gear or 2nd gear, execute the normal gear shifting. If the request is N gear, keep N gear temporarily. If abnormal gear shifting or failure to shift gear occurs again during the gear shifting under the premise of meeting condition 1, as described in 2, bCond_Neutral==1, the gear request is N gear, and the gear shifting action is executed; repeat this process until the gear shifting is successful, or the gear shifting still fails after the set number of times, and the corresponding gear fault is confirmed and output;

[0036] Among them, A5 and B5 are executed at the same time.

[0037] Furthermore, the duration of T_GearRetrying needs to cover the expected number of attempts to shift gears and engage gears, and be set to be several times of T_BlockOutResetHld and T_JumpOutResetHld.

[0062] Embodiment 1

[0063] Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention is a schematic diagram of a multi-speed hybrid system configuration and its working mode. The present invention is applicable to all hybrid multi-speed transmissions of the configuration shown in the figure. The present invention relates to a method for forcing a multi-speed hybrid transmission to shift to neutral gear. After the output of the gear shifting signal is output by the decision module, it is used as an actual gear shift execution request. There is no requirement for the actual gear shift execution mechanism (such as electric execution, hydraulic execution, pneumatic execution).

[0064] See also Figure 5This embodiment provides a method for post-processing abnormal gear separation of a 2-speed hybrid transmission. The method can be executed by a post-processing device for abnormal gear separation of a multi-speed hybrid transmission in an embodiment of the present invention. The device can be implemented in software and / or hardware, and is specifically divided into the following parts:

[0065] 1. Through the function prerequisite judgment module, the gear abnormal exit and re-shifting post-processing prerequisite is judged, and the prerequisite is output in real time to the flag bit to see whether it meets the gear abnormal separation detection module, as follows:

[0066] A1. The system has no confirmed abnormal gear position fault;

[0067] B1. There is no leakage in the hydraulic system;

[0068] C1. There are no faults in the sensors related to the gear shifting execution; (related to the design of the execution system, such as the shift fork position sensor and the main oil circuit pressure sensor);

[0069] D1. All the actuators related to gear shifting are free of faults; (related to the design of the execution system. If it is a hydraulic gear shifting execution system, it should include related solenoid valves, mechanical valves, etc.);

[0070] E1. The main oil circuit pressure is established normally (such as hydraulic shift execution system);

[0071] Among them, when A1, B1, C1, D1, and E1 are all met, it is determined that the prerequisite for post-processing of abnormal gear exit and gear shifting is met.

[0072] 2. When the prerequisite is met, the gear abnormal separation detection module, combined with the G1BlockOut, G1JumpOut, G2BlockOut, and G2JumpOut signals output by the diagnosis module, performs gear abnormal separation state detection and clearing, and outputs in real time whether the gear 1 and 2 have gear abnormal separation state flags; when G1Out=1 or G2Out=1, it means that the gear 1 or 2 has gear abnormal separation; when G1Out=0 and G2Out=0, it means that the gear 1 and 2 have gear abnormal separation flags cleared; the G1Out and G2Out flags are output to the target N gear arbitration module in real time; the details are as follows:

[0073] A2. Receive the 1st gear cannot be engaged, i.e., G1BlockOut flag, the 1st gear abnormal separation flag G1Out=1, and start timing; when the set time T_BlockOutResetHld is exceeded, the supplementary gear action setting time is executed, or receive the 1st gear separation flag, the 1st gear abnormal separation flag is cleared G1Out=0;

[0074] B2. Receive the 1st gear unexpected jump out G1JumpOut flag, 1st gear abnormal separation flag G1Out=1, and start timing. If the set time T_JumpOutResetHld is exceeded, the set time of the supplementary gear action is executed, or receive the 1st gear separation flag, 1st gear abnormal separation flag is cleared G1Out=0;

[0075] C2. Receive the 2nd gear cannot be engaged, i.e., G2BlockOut flag, the 2nd gear abnormal separation flag G2Out=1, and start timing; when the set time T_BlockOutResetHld is exceeded, the gear-shifting action setting time is executed, or receive the 2nd gear separation flag, the 2nd gear abnormal separation flag is cleared G2Out=0;

[0076] D2. Receive the 2nd gear unexpected jump (G2JumpOut) flag, the 2nd gear abnormal separation flag G2Out=1, and start timing; when the set time T_JumpOutResetHld is exceeded, the gear-switching action setting duration is executed, or receive the 2nd gear separation flag, the 2nd gear abnormal separation flag is cleared G2Out=0.

[0077] 3. The target N gear arbitration module combines the VCU request target gear position and the VCU communication fault signal output by the vehicle control module to make a joint decision and output the requested gear position; the target N gear arbitration module includes a target gear position output N activation condition judgment submodule and a target gear position N deactivation condition judgment submodule, which are as follows:

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

[0079] A3, input gear available 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, VCU input target gear request is 2nd gear, but the 2nd gear abnormal separation flag is 1;

[0082] D3, communication failure of upper controller;

[0083] Among them, 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 position N deactivation condition judgment submodule is as follows:

[0085] A4, the input gear available status is N gear is not available;

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

[0087] C4, the input gear available status is N gear available, the upper controller communication is normal, the VCU input target gear request is 2 gear, and the 2 gear abnormal separation flag is restored to 0;

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

[0089] Among them, when A4||B4||C4||D4, the exit target gear is forced to be N bCond_Neutral=0.

[0090] 4. The gear execution and post-processing module is used to receive the requested gear output by the target N gear arbitration module in real time, and reasonably trigger the execution of the forbidden parallel connection and the supplementary gear removal according to other mandatory gear requests and the vehicle status, as follows:

[0091] A5. Forbidden to parallel connection: After the abnormal state of gear is triggered, G1Out==1 or G2Out==1, the gear re-engagement flag of a specific duration T_GearRetrying is output: GearRetrying=1; when GearRetrying==1, it is considered that the system is re-engaging the gear, and a clutch separation request is sent to the VCU, prohibiting the system from entering the parallel connection mode, and triggering the response execution component at the same time to ensure the power source of the system re-engagement;

[0092] B5. Execute the action of supplementary gear shifting: When condition 1 is met, when bCond_Neutral==1, the output gear request is N gear, and the gear shifting action is executed. When bCond_Neutral==0, respond to the VCU gear request. If the request is 1st gear or 2nd gear, execute the normal gear shifting. If the request is N gear, keep N gear temporarily. If abnormal gear shifting or failure to shift gear occurs again during the gear shifting under the premise of meeting condition 1, as described in 2, bCond_Neutral==1, the gear request is N gear, and the gear shifting action is executed; repeat this process until the gear shifting is successful, or the gear shifting still fails after the set number of times, and the corresponding gear fault is confirmed and output;

[0093] Among them, A5 and B5 are executed at the same time.

[0094] Furthermore, the duration of T_GearRetrying needs to cover the expected number of attempts to shift gears and engage gears, and be set to be several times of T_BlockOutResetHld and T_JumpOutResetHld.

[0095] In summary, the present invention is based on the judgment and processing of the abnormal disengagement state of the system gear, the judgment of the available state of the current gear and the input signal of the target gear, and comprehensively judges and outputs a signal to force the target gear to be the N gear, thereby realizing the output of multiple supplementary gear-release action requests under the abnormal gear state, and designs a response plan. When the supplementary gear-release action is executed in the abnormal disengagement state of the system gear, it interacts with the vehicle controller to request to disengage the clutch to avoid derivative faults.

[0096] It should be noted that the above embodiment describes a post-processing method for abnormal transmission gear disengagement of a 2-speed hybrid system. In fact, a post-processing method for abnormal transmission gear disengagement of a multi-speed hybrid system can also be processed according to the method described in the present invention and is within the protection scope of the present invention.
