Abstract
Description
Technical Field
[0001] The present invention relates to the field of vehicle control technology, and in particular to a vehicle gear shifting method, device, electronic device and storage medium. Background Technology
[0002] With the development of the vehicle industry, the safety factor during vehicle gear shifting is closely related to the personal safety of the driver.
[0003] Currently, dual-clutch automatic transmissions generally have two clutches: an odd-numbered clutch for odd-numbered gears and an even-numbered clutch for even-numbered gears. They can automatically shift gears based on vehicle speed and accelerator pedal opening. Most dual-clutch automatic transmissions support both automatic and manual shifting modes. Figure 1 This is a schematic diagram of a vehicle gear shifter in the prior art, such as... Figure 1 As shown, when the shift lever 000 is in the D position 010, the transmission enters automatic shifting mode. At this time, it automatically selects the appropriate gear based on the accelerator pedal opening and vehicle speed to meet the driver's needs for comfort and power. When the shift lever 000 moves to the right from the D position into the M position 020, the transmission enters manual shifting mode. In this mode, the driver can manually shift gears by moving the shift lever up or down. In existing technology, during vehicle gear shifting operations, a shift torque request is generally sent to the engine control unit based on the magnitude of the engine torque request value. Figure 2 This is a schematic diagram of a vehicle shifting torque increase method in the prior art, such as... Figure 2 As shown, when the vehicle needs to downshift from 5th gear to 4th gear, after the torque exchange phase is completed, a shift torque increase request is sent to the engine control unit, so that the engine speed is increased to near the target gear clutch speed, so as to facilitate the smooth engagement of the target 4th gear.
[0004] In the process of developing this invention, the inventors discovered the following defects in the prior art: When performing vehicle gear shifting operations, the prior art can determine whether to allow sending a gear shifting torque request to the engine control unit simply by judging the magnitude of the engine torque request value, ignoring the problem that other factors may affect the vehicle gear shifting operation, thus reducing the safety of vehicle gear shifting. Summary of the Invention
[0005] This invention provides a vehicle gear shifting method, apparatus, electronic device, and storage medium, which can improve the safety of vehicle gear shifting.

[0018] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the vehicle shifting method described in any embodiment of the present invention.
[0019] This invention, through a transmission control unit responding to a real-time generated engine torque increase request value, acquires shift-related reference parameters such as the current vehicle's shift condition reference parameters, clutch state reference parameters, engine speed reference parameters, and torque increase request value reference parameters. Based on these shift-related reference parameters, the engine torque increase request value is monitored, and the current shift operation of the vehicle is controlled according to the monitoring results. This solves the problem of poor safety during existing vehicle shifting processes and improves the safety of vehicle shifting.

[0033] Example 1
[0034] Figure 3 This is a flowchart of a vehicle gear shifting method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where safe gear shifting operations are performed while the vehicle is in motion, taking into account multiple influencing factors. The method can be executed by a vehicle gear shifting device, which can be implemented in software and / or hardware, and is generally integrated into an electronic device. This electronic device can be a terminal device with vehicle gear shifting functionality, or a server device used to simulate and test vehicle functions, etc. The electronic device acts as a transmission control unit to execute the vehicle gear shifting method. This embodiment of the present invention does not limit the specific type of electronic device. Correspondingly, as... Figure 3 As shown, the method includes:
[0035] S110. In response to the real-time generated engine torque increase request value, obtain the current vehicle's shift-related reference parameters; wherein, the shift-related reference parameters may include shift condition reference parameters, clutch status reference parameters, engine speed reference parameters, and torque increase request value reference parameters, etc.
[0036] Among them, the engine torque increase request value can be understood as the torque value that the engine needs to increase to after a downshift. Shift-related reference parameters can be reference parameters describing vehicle operating state parameters and vehicle component state parameters associated with the shift operation. Shift condition reference parameters can be reference parameters describing the current vehicle state when shifting gears. Clutch state reference parameters can be parameters describing the clutch state corresponding to the original gear before shifting, or parameters describing the clutch state corresponding to the target gear after shifting. Engine speed reference parameters can be reference parameters describing the current engine speed of the vehicle. Torque increase request value reference parameters can be reference parameters describing the engine torque increase request value.
[0037] In this embodiment of the invention, after calculating the engine torque increase request information, the transmission control unit can respond to the real-time generated engine torque increase request value and obtain the current vehicle shift condition reference parameters, clutch state reference parameters, engine speed reference parameters, and torque increase request value reference parameters, etc.
[0038] S120: Monitor the engine torque increase request value based on the shift-related reference parameters.
[0039] Accordingly, after obtaining the shift-related reference parameters of the current vehicle, the transmission control unit can monitor the engine torque increase request value according to the shift-related reference parameters to obtain the monitoring result of the engine torque increase request value, and then determine whether the current vehicle status meets the safe shifting conditions based on the monitoring result of the engine torque increase request value.
[0040] S130: Control the current gear shift operation of the current vehicle based on the monitoring results of the engine torque increase request value.
[0041] In this embodiment of the invention, the transmission control unit can control the transmission of the current vehicle to perform a shift operation based on the monitoring results of the engine torque increase request value, and control the engine control unit of the current vehicle to perform a torque increase request, thereby completing the current shift operation of the current vehicle.
[0042] This invention, through a transmission control unit responding to a real-time generated engine torque increase request value, acquires shift-related reference parameters such as the current vehicle's shift condition reference parameters, clutch state reference parameters, engine speed reference parameters, and torque increase request value reference parameters. Based on these shift-related reference parameters, the engine torque increase request value is monitored, and the current shift operation of the vehicle is controlled according to the monitoring results. This solves the problem of poor safety during existing vehicle shifting processes and improves the safety of vehicle shifting.
[0043] Example 2
[0044] Figure 4 This is a flowchart of a vehicle gear shifting method provided in Embodiment 2 of the present invention. This embodiment further optimizes and expands upon the above embodiment, providing various specific optional implementation methods for monitoring the engine torque increase request value based on gear shifting associated reference parameters. Correspondingly, such as... Figure 4 As shown, the method may include:
[0045] S210. In response to the real-time generated engine torque increase request value, obtain the current vehicle's shift-related reference parameters; wherein, the shift-related reference parameters may include shift condition reference parameters, clutch status reference parameters, engine speed reference parameters, and torque increase request value reference parameters, etc.
[0046] S220: Monitor the engine torque increase request value based on the shift association reference parameters.
[0047] Optionally, the shift condition reference parameters may include the current vehicle speed, the shift torque increase speed limit, and the current vehicle shift status. Monitoring the engine torque increase request value based on the shift-related reference parameters may include: obtaining the current vehicle speed, the shift torque increase speed limit, and the current shift status; and determining that the engine torque increase request value passes the shift condition monitoring if the current vehicle speed is greater than or equal to the shift torque increase speed limit and the current shift status is in the shift process state.
[0048] Among them, the speed limit for shifting and increasing torque can be a preset limit value of the current vehicle speed when the vehicle is performing a shifting and torque-increasing operation.
[0049] Correspondingly, the transmission control unit can determine the shift condition by acquiring the current vehicle speed, the shift torque increase speed limit, and the current shift status. If the current vehicle speed is greater than or equal to the shift torque increase speed limit and the current shift status is in the shift process state, the shift condition determination can be considered successful. In this way, the monitoring result of the shift condition for the engine torque increase request value can be determined as successful, and the next step can be carried out.
[0050] Optionally, the clutch status reference parameters may include the target gear clutch status and the original gear clutch status before shifting. Monitoring the engine torque increase request value based on the shift-related reference parameters may include: determining the engine torque increase request value through clutch status monitoring when the target gear clutch status is determined to be a first clutch status and the original gear clutch status before shifting is a second clutch status; wherein, the first clutch status may include a slipping state or a disengaged state; and the second clutch status may include a disengaged state.
[0051] The target gear clutch state can be the clutch state after the current gear shift. The original gear clutch state can be the clutch state before the current gear shift. Clutch slippage state can be understood as the state when the clutch pressure is greater than the half-engagement point pressure and the clutch speed difference is greater than the closing slippage difference. Clutch disengagement state can be understood as the state when the clutch pressure is less than the half-engagement point pressure.
[0052] Correspondingly, the transmission control unit can determine the clutch status. If it is determined that the clutch status of the target gear is slipping or disengaged, and the original gear clutch status is disengaged before shifting, the clutch status determination can be considered successful. In this way, the clutch status monitoring result of the engine torque increase request value can be determined to be successful, and the next step can be carried out.
[0053] Optionally, the engine speed reference parameters may include the current engine speed, the target gear clutch speed, and the clutch slip difference speed limit, etc. Monitoring the engine torque increase request value based on the shift-related reference parameters may include: calculating the sum of the target gear clutch speed and the clutch slip difference speed limit; and determining the engine torque increase request value through engine speed monitoring if the current engine speed is less than or equal to the sum of the target gear clutch speed and the clutch slip difference speed limit.
[0054] The target gear clutch speed value can be the clutch speed value after the current gear shift. The clutch slip difference speed limit is also the preset limit value of the clutch slip difference speed.
[0055] Correspondingly, the transmission control unit can determine the engine speed and calculate the sum of the target gear clutch speed value and the clutch slip difference speed limit. If the current engine speed value is less than or equal to the sum of the target gear clutch speed value and the clutch slip difference speed limit, the engine speed determination can be considered successful. Then, the engine speed monitoring result of the engine torque increase request value can be determined as successful, and the next step can be carried out.
[0056] Optionally, the torque increase request value reference parameters may include the engine torque increase request value and the engine shift torque increase limit, etc. Monitoring the engine torque increase request value according to the shift-related reference parameters may include: determining that the engine torque increase request value is monitored through the torque increase request when it is determined that the engine torque increase request value is less than or equal to the engine shift torque increase limit.
[0057] Correspondingly, the transmission control unit can determine the engine torque increase request value. If it is determined that the engine torque increase request value is less than or equal to the engine shift torque increase limit, the engine torque increase request value determination can be considered passed. Thus, the monitoring result of the engine torque increase request value can be determined as passed, and the next step can be carried out.
[0058] S230. Determine whether the monitoring result of the engine torque increase request value is "monitoring passed". If yes, proceed to S240; otherwise, proceed to S250.
[0059] Specifically, the transmission control unit can determine whether the monitoring result of any shift-related reference parameter of the engine torque increase request value is a pass. If the monitoring result of any shift-related reference parameter of the engine torque increase request value is a pass, then S240 is executed; if the monitoring result of any shift-related reference parameter of the engine torque increase request value is a fail, then S250 is executed.
[0060] S240, Send a shift torque increase request to the engine control unit; wherein, the shift torque increase request may include an engine torque increase request value, used to request the engine control unit to control the current engine speed to increase to the target gear clutch speed.
[0061] Correspondingly, if the transmission control unit determines that the monitoring result of the engine torque increase request value is passed, it can send a shift torque increase request to the engine control unit to enable the current vehicle to actively perform a shift torque increase operation.
[0062] S250, prohibit sending shift torque increase requests to the engine control unit.
[0063] Correspondingly, if the transmission control unit determines that the monitoring result for the engine torque increase request value has failed, it will prohibit sending a shift torque increase request to the engine control unit. It should be noted that in this situation, the vehicle can still perform gear shifts by passively performing a shift torque increase operation.
[0064] For example, combining the above-mentioned optional shift-related reference parameters of the current vehicle can yield a preferred embodiment. Figure 5 This is a flowchart illustrating a vehicle gear shifting method according to Embodiment 2 of the present invention. In a specific example, such as... Figure 5 As shown, before sending a shift torque increase request to the engine control unit, the transmission control unit needs to perform four steps of determination: shift condition determination, clutch status determination, engine speed determination, and engine torque increase request determination. Figure 6 This is a flowchart illustrating a vehicle gear shifting method according to Embodiment 2 of the present invention, as shown below. Figure 6 As shown, the four-step determination process can specifically include:
[0065] Step 1: Shift Condition Determination. The transmission control unit responds to the real-time generated engine torque increase request value. If the vehicle speed is greater than or equal to the shift torque increase speed limit, and the current shift state is in the process of shifting, the transmission control unit can determine that the shift condition determination has passed. For example, the shift torque increase speed limit ranges from 0-10 km / h, and the current shift state is determined based on the transmission's normal shift process algorithm.
[0066] Step 2: Clutch Status Determination. The clutch status determination is considered successful when the target gear clutch is in a slipping or disengaged state, and the original gear clutch was disengaged before the shift. For example, the slip difference can range from 10 to 100 rpm.
[0067] Step 3: Engine Speed Determination. The engine speed determination is considered successful when the engine speed is less than or equal to the target gear clutch speed plus the clutch slip difference speed limit. For example, the clutch slip difference speed limit can be set between 0-100 rpm.
[0068] Step 4: Engine Torque Request Determination. When the engine torque request value generated by the transmission control unit is less than or equal to the engine shift torque limit, the engine torque request value determination is considered successful. For example, the engine shift torque limit is 0-100 Nm.
[0069] It should be noted that in this preferred embodiment, a shift torque increase request is only allowed to be sent to the engine control unit after all four of the above determinations have passed; otherwise, a shift torque increase request is prohibited from being sent to the engine control unit.
[0070] Figure 7 This is a schematic diagram of the hardware structure of a vehicle gear shifting method provided in Embodiment 2 of the present invention. Figure 7 As shown, the hardware structure of this vehicle shifting method includes four parts: a transmission control unit, a vehicle information unit, a transmission information unit, and an engine control unit. The transmission control unit internally runs a software algorithm to implement this preferred embodiment. The transmission control unit receives vehicle speed and accelerator pedal information from the vehicle information unit, and combines this information with clutch pressure, clutch speed, and gear position information generated by the transmission information unit to send a shift torque increase request value to the engine control unit.
[0071] It should be noted that any arrangement or combination of the technical features in the above embodiments also falls within the protection scope of this invention.
[0072] The technical solution of this invention improves the safety and flexibility of the vehicle shifting method by monitoring one or more of the shifting-related reference parameters, such as shifting condition reference parameters, clutch state reference parameters, engine speed reference parameters, and torque increase request value reference parameters.

Figure 8 As shown, the vehicle shifting device includes: a shifting-related reference parameter acquisition module 310, an engine torque increase request value monitoring module 320, and a current shifting operation control module 330.
[0075] The shift-related reference parameter acquisition module 310 is used to acquire the shift-related reference parameters of the current vehicle in response to the real-time generated engine torque increase request value. The shift-related reference parameters include shift condition reference parameters, clutch status reference parameters, engine speed reference parameters, and torque increase request value reference parameters. The engine torque increase request value monitoring module 320 is used to monitor the engine torque increase request value according to the shift-related reference parameters. The current shift operation control module 330 is used to control the current shift operation of the current vehicle according to the monitoring result of the engine torque increase request value.
[0076] This invention, through a transmission control unit responding to a real-time generated engine torque increase request value, acquires shift-related reference parameters such as the current vehicle's shift condition reference parameters, clutch state reference parameters, engine speed reference parameters, and torque increase request value reference parameters. Based on these shift-related reference parameters, the engine torque increase request value is monitored, and the current shift operation of the vehicle is controlled according to the monitoring results. This solves the problem of poor safety during existing vehicle shifting processes and improves the safety of vehicle shifting.

[0078] Optionally, the clutch status reference parameters may include the target gear clutch status and the original gear clutch status before shifting. The engine torque increase request value monitoring module 320 is specifically used to: determine the engine torque increase request value through clutch status monitoring when it is determined that the target gear clutch status is the first clutch status and the original gear clutch status before shifting is the second clutch status; wherein, the first clutch status includes slipping state or disengagement state; the second clutch status includes disengagement state.
[0079] Optionally, the engine speed reference parameters may include the current engine speed value, the target gear clutch speed value, and the clutch slip difference speed limit, etc. The engine torque increase request value monitoring module 320 is specifically used to: calculate the sum of the target gear clutch speed value and the clutch slip difference speed limit; and determine the engine torque increase request value through engine speed monitoring if it is determined that the current engine speed value is less than or equal to the sum of the target gear clutch speed value and the clutch slip difference speed limit.
[0080] Optionally, the torque increase request value reference parameters may include the engine torque increase request value and the engine shift torque increase limit, etc. The engine torque increase request value monitoring module 320 is specifically used to: determine the engine torque increase request value through torque increase request monitoring when it is determined that the engine torque increase request value is less than or equal to the engine shift torque increase limit.
[0081] Optionally, the current shift operation control module 330 is specifically used to: send a shift torque increase request to the engine control unit when the monitoring result of the engine torque increase request value is determined to be a passing monitoring result; and prohibit sending a shift torque increase request to the engine control unit when the monitoring result of the engine torque increase request value is determined to be a failing monitoring result; wherein, the shift torque increase request includes an engine torque increase request value, which is used to request the engine control unit to control the current engine speed to increase to the target gear clutch speed.
