[0002] Currently, automatic transmissions are used in several important areas, including passenger cars and commercial vehicles. They can achieve continuously variable speeds, providing drivers with good driving performance and comfort. As the application of automatic transmissions becomes more and more widespread, people's requirements for their comfort and stability are also getting higher and higher.

[0003] With the gradual popularization of automobiles, various complex working conditions are becoming more and more numerous. Traditional automatic transmissions currently require fine calibration during the gear shifting process. Once poorly controlled, gear shifting shock, dragging, power loss, etc. are likely to occur, affecting the driving experience; especially after releasing the accelerator during the gear shifting process, the engine torque drops rapidly, from powered to unpowered. At this time, if poorly controlled, problems such as long gear shifting time and torque interference are likely to occur. Therefore, it is particularly important for the electronic control unit to identify and control in a timely manner to improve driving comfort and stability. Summary of the Invention

[0029] Specifically, in many automobile automatic transmissions, when shifting from pressing the accelerator to releasing the accelerator, the engine speed and torque drop rapidly, and the engine torque changes from positive torque to negative torque, which can easily cause gear shift shock or severe drag feeling, seriously affecting comfort.

[0030] The torque increase request control method for automatic transmission gear shifting proposed in the embodiment of the present disclosure, when a series of parameters such as the engine non-intervention torque and throttle opening are known, monitors the current gear shifting conditions and sends a suitable torque increase request, so that the engine torque and speed can smoothly decrease when the throttle is released during the gear shifting process, reducing drag and impact and improving driving comfort. That is, it can timely monitor the throttle release during the gear shifting process and send a torque increase request, so that the engine torque and speed can slowly decrease according to the calibrated slope, reducing the occurrence of impact and drag, and improving driving comfort.

[0031] Figure 1 This is a flow chart of a method for controlling a torque increase request for automatic transmission shifting provided by an embodiment of the present disclosure. This method can be executed by a device for controlling a torque increase request for automatic transmission shifting, wherein the device can be implemented using software and / or hardware and can generally be integrated into an electronic device. Figure 1 As shown, the method includes:

[0032] Step 101: In the initial stage, the torque increase target torque is obtained as a calibrated value, and whether the first energy level condition of the torque increase control stage is met is detected. When the first energy level condition is detected to be met, a torque increase request is sent to the engine; wherein the torque increase request includes the basic target torque.

[0033] In the embodiment of the present disclosure, the initial stage refers to the default stage, that is, the vehicle's electronic control unit adopts a state machine control method and enters the initial stage by default; usually the target torque for the initial stage is the default value, that is, the calibrated value, which can be selected and set according to the actual application scenario.

[0034] In the embodiment of the present disclosure, when entering the initial stage, real-time detection is performed to determine whether the first energy level condition of the torque increase control stage is met. The first energy level condition includes that the function total enable switch is set to 1, the gear shift enable switch is set to 1, the engine cooling temperature is within a preset limit range, the engine non-intervention torque is greater than a calibrated first limit, and the throttle is switched from pressing the accelerator to releasing the accelerator, and the difference between the maximum value of the engine non-intervention torque and the engine non-intervention torque is greater than a calibrated difference, and the engine non-intervention torque is less than a calibrated second difference.

[0035] Specifically, it is detected whether the function total enable position switch is set to 1, whether the gear shift enable position switch is set to 1, whether the engine cooling temperature is within the preset limit range, whether the engine non-intervention torque is greater than the calibrated first limit, and whether the throttle is switched from pressing the throttle to releasing the throttle. After the function total enable position switch is set to 1, the gear shift enable position switch is set to 1, the engine cooling temperature is within the preset limit range, the engine non-intervention torque is greater than the calibrated first limit, and the throttle is switched from pressing the throttle to releasing the throttle, it is detected whether the difference between the maximum value of the engine non-intervention torque and the engine non-intervention torque is greater than the calibrated difference and whether the engine non-intervention torque is less than the calibrated second limit; wherein the calibrated second limit is greater than the calibrated first limit, when the difference between the maximum value of the engine non-intervention torque and the engine non-intervention torque is greater than the calibrated difference and the engine non-intervention torque is less than the calibrated second limit, it is determined that the first enable position condition is met, thereby sending a torque increase request including the basic target torque to the engine.

[0036] Step 102 : Based on the torque increase request, the torque increase target torque is controlled to be the basic target torque, and the torque increase target torque is controlled to be reduced from the basic target torque according to a preset first reduction strategy to obtain the torque in the torque increase control phase.

[0037] In the embodiment of the present disclosure, when the first energy level condition is met, it is necessary to control the torque increase target torque to increase to the basic target torque; wherein, the basic target torque can be obtained by querying the current gear shift information and the preset information table.

[0038] Furthermore, when the torque-up target torque is the basic target torque, it indicates that the first torque-up control phase is finished, and the torque-up target torque needs to be further controlled to be reduced from the basic target torque according to a preset first reduction strategy to obtain the torque in the torque-up control phase.

[0039] Specifically, the basic target torque may be controlled to decrease according to a preset torque change value or to decrease over time according to a preset torque change rate to obtain the torque in the torque increase control phase.

[0040] Step 103, continue to detect whether the first energy level condition of the torque increase control stage is met, and when it is detected that the first energy level condition is not met, determine that the second energy level condition is met, and control the torque increase target torque to reduce the torque from the torque increase control stage according to the preset second reduction strategy to obtain the target torque.

[0041] In the embodiment of the present disclosure, in the process of controlling the torque increase target torque to decrease from the basic target torque according to the preset first decrease strategy, it will continue to detect whether the first energy level condition of the torque increase control stage is met. When it is detected that the first energy level condition is not met, it is determined that the second energy level condition is met, and the torque increase target torque is controlled to decrease from the torque increase control stage according to the preset second decrease strategy to obtain the target torque. That is, the torque increase target torque can be controlled to decrease according to the preset torque change value or to decrease over time according to the preset torque change rate to obtain the target torque; wherein the target torque is less than or equal to the difference between the engine no-intervention torque and the calibration value.

[0042] The disclosed embodiment provides a torque-up request control scheme for automatic transmission shifting. In the initial stage, a torque-up target torque is obtained as a calibrated value. A first energy level condition of the torque-up control stage is detected. When the first energy level condition is detected to be satisfied, a torque-up request is sent to the engine. The torque-up request includes a base target torque. Based on the torque-up request, the torque-up target torque is controlled as the base target torque, and the torque-up target torque is controlled to be reduced from the base target torque according to a preset first reduction strategy to obtain a torque in the torque-up control stage. Further detection is performed to determine whether the first energy level condition of the torque-up control stage is satisfied. If the first energy level condition is not satisfied, the second energy level condition is determined to be satisfied, and the torque-up target torque is controlled to be reduced from the torque in the torque-up control stage according to a preset second reduction strategy to obtain a target torque. Thus, by properly sending the torque-up request, the engine torque is slowly reduced, thereby avoiding shock and drag caused by a rapid torque drop and improving driving comfort.

[0043] Figure 2 This is a flow chart of another automatic transmission shifting torque request control method provided by the present disclosure. This embodiment further optimizes the above automatic transmission shifting torque request control method based on the above embodiment. Figure 2 As shown, the method further includes:

[0044] Step 201, in the initial stage, obtains the target torque for the torque increase as a calibrated value, detects whether the total enable switch of the function is set to 1, whether the shift enable switch is set to 1, whether the cooling temperature of the engine is within the preset limit range, whether the engine non-intervention torque is greater than the calibrated first limit, and whether the throttle is switched from being pressed to being released.

[0045] Step 202: After the function total enable switch is set to 1, the shift enable switch is set to 1, the engine cooling temperature is within a preset limit range, the engine no-intervention torque is greater than a calibrated first limit, and the throttle is switched from being pressed to being released, detect whether the difference between the maximum value of the engine no-intervention torque and the engine no-intervention torque is greater than a calibrated difference and whether the engine no-intervention torque is less than a calibrated second limit.

[0046] Step 203: When the difference between the maximum engine no-intervention torque and the engine no-intervention torque is greater than a calibrated difference and the engine no-intervention torque is less than a calibrated second limit, it is determined that the first energy level condition is met, and a torque increase request is sent to the engine; wherein the torque increase request includes a basic target torque.

[0047] Specifically, entering the torque increase control stage requires meeting the first energy position condition, which includes the function total enable position switch being set to 1, the gear shift enable position switch being set to 1, the engine cooling temperature being within the preset limit range (which can be calibrated according to actual application needs), the engine non-intervention torque being greater than the calibrated first limit value (which can be calibrated according to actual application needs), and the throttle being changed from being pressed to being released.

[0048] It should be noted that the two conditions of the engine's non-intervention torque being greater than the calibrated first limit and the throttle changing from being pressed to being released are trigger conditions. Once these two conditions are met, it is assumed that the two conditions are always met until they are reset after the gear shift changes.

[0049] Specifically, after the above conditions are met, it is detected whether the first energy level condition is met, which also includes that the difference between the monitored maximum value of the engine no-intervention torque and the engine no-intervention torque is greater than a calibrated difference (which can be calibrated according to actual application needs) and the engine no-intervention torque is less than a calibrated second limit value (which can be calibrated according to actual application needs).

[0050] The current gear shift information is obtained, and a query is performed based on the current gear shift information and a preset information table to obtain a basic target torque.

[0051] Step 204 : Based on the torque increase request, the torque increase target torque is controlled as the basic target torque, the torque change rate of the torque increase control phase is obtained, and the basic target torque is controlled to decrease according to the torque change rate of the torque increase control phase to obtain the torque increase control phase torque.

[0052] The current gear shift information is obtained, and based on the current gear shift information and the basic target torque, a preset torque change rate table is searched to obtain the torque change rate in the torque increase control phase.

[0053] Step 205: Continue to detect whether the first energy level condition of the torque increase control stage is met. When it is detected that the first energy level condition is not met, determine that the second energy level condition is met, obtain the calibrated torque change rate of the torque increase control exit stage, and control the torque in the torque increase control stage to continue to decrease according to the calibrated torque change rate until the target torque is reached.

[0054] The target torque is less than or equal to the difference between the engine no-intervention torque and the calibrated value.

[0055] For example, Figure 3 As shown, step 3.1 enters the P0 stage by default; step 3.2 determines whether the entry condition E1 is met; if so, execute step 3.3 to enter the P1 stage; step 3.4 completes the P1 stage and enters the P2 stage; step 3.5 completes the P2 stage and enters the P8 stage; step 3.6 completes the P8 stage and enters the P0 stage; in addition, step 3.7 is also executed in the P1 and P2 stages to check whether the exit condition E2 is met, and if so, execute step 3.5.

[0056] Specifically, the torque increase request control method for automatic transmission gear shifting includes the enabling prerequisites for entering the torque increase control stage and each control stage, which is divided into four control stages, namely P0, P1, P2, and P8; among them, the PO stage is the default stage (initial stage), the P1 and P2 stages are the torque increase control stages, and P8 is the torque increase control exit stage; the state machine control method is adopted, and the P0 stage is entered by default. When the torque increase control stage enable bit E1 (the first enable bit condition) is established, the torque increase control stages P1 and P2 are entered in turn. When the torque increase control stage exit enable bit E2 (the second enable bit condition) is established, it will return from the current process control stage to P8, and finally return to P0.

[0057] Specifically, the P1 stage will send a torque increase request to the engine, and the torque increase target torque is equal to the basic target torque TqBaseTgt (obtained by looking up the table based on the current gear shift in the first cycle of the P1 stage). The P2 stage will slowly decrease from TqBaseTgt according to the calibrated slope, and gradually decrease to the engine no-intervention torque PumpTqNoInt.

[0058] Specifically, the condition for the enable bit E2 of the exit process control phase to be met (the second enable bit condition) is that when E1 is not met, E2 is met, that is, the process exits immediately after the entry condition is not met.

[0059] Specifically, in the P1 stage, the target torque for controlling the torque increase TgtTq is equal to the basic target torque TqBaseTgt. The completion condition of the P1 stage can be understood as the stage is completed after the P1 stage is established for one cycle. The purpose of the P1 stage is to assign an initial target torque, that is, to control the target torque for controlling the torque increase to be the basic target torque.

[0060] Specifically, in the P2 phase, the torque increase target torque TgtTq=the basic target torque TqBaseTgt+the torque change rate in the torque increase control phase multiplied by time (obtained by looking up the table based on the current gear shift information and the basic target torque TqBaseTgt).

[0061] It should be noted that the minimum value of the torque increase target torque TgtTq is =max(PumpTqNoInt, TqBaseTgt); the completion condition of the P2 stage is that the P2 stage is completed when the E2 exit condition is met.

[0062] Finally, in the P8 stage, the torque increase target torque TgtTq = the torque increase control stage torque TgtTqZ1 + the calibrated torque change rate multiplied by time; the completion condition of the P8 stage is that the torque increase target torque TgtTq is the target torque and is <= the engine no-intervention torque PumpTqNoInt minus the calibrated value.

[0063] For example, Figure 4 As shown, the vertical axis is Torque / Nm, that is, how much torque per Newton meter; the horizontal axis is Time / s, that is, per second; the solid line is the torque value; the dotted line is the engine torque; as time goes by, it goes through the P0 stage, P1 stage, P2 stage, P8 stage and returns to the P0 stage; the basic target torque TgBaseTgt is a fixed value.

[0064] It can be understood that the torque increase target torque TgtTq is gradually catching up with the engine non-intervention torque PumpTqNoInt at a certain torque change rate. If PumpTqNoInt is greater than the TqBaseTgt value in the P2 stage, the torque increase target torque will continue to catch up with the engine non-intervention torque PumpTqNoInt. If PumpTqNoInt is less than the TqBaseTgt value, the torque increase target torque will be limited by TqBaseTgt, that is, the minimum torque increase target torque cannot be lower than TqBaseTgt at this time. The torque increase change diagram is as follows Figure 4 As shown; in addition, the engine no-intervention torque PumpTqNoInt means the theoretical value when the engine does not respond to the torque increase request. At this time, the actual torque of the engine should change with the torque increase target torque (it can be considered that the torque increase target torque at this time is the actual torque value of the engine). The engine no-intervention torque PumpTqNoInt is only a theoretical value of logical judgment.

[0065] Therefore, the accelerator release during the gear shift process is monitored in a timely manner, and a torque increase request is issued, so that the engine torque and speed slowly decrease according to the calibrated slope, reducing the occurrence of impact and drag and improving driving comfort.
