Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a transmission gear control method and device, electronic equipment and computer readable storage medium. BACKGROUND

[0002] Currently, in order to improve the driving pleasure of users, vehicle manufacturers usually equip vehicles with steering wheel shifters. When the driver shifts the steering wheel shifter to manually increase or decrease the gear, the vehicle will either automatically upshift or the engine will maintain a high speed but the transmission will remain in the current gear (or called lock gear) when full throttle acceleration.

[0003] However, since the current transmission control system only has one manual mode shift map, and in the manual mode and non-manual mode, only one of the automatic upshift or no automatic upshift (i.e. lock gear) logic can be selected. If the automatic upshift logic is selected in the manual mode, the vehicle can automatically upshift under full throttle according to the preset threshold, but the driver cannot independently upshift, which lacks the sense of communication between the driver and the vehicle, greatly reducing the driver's pleasure and passion. If the no automatic upshift logic is selected in the non-manual mode, the transmission is prohibited from automatically upshifting under full throttle according to the preset threshold. Since the vehicle cannot continuously accelerate, the lap time of the driver on the race track will be reduced. At the same time, since the vehicle cannot increase speed by upshifting to overtake, the driver will be in panic to some extent, which is easy to cause rear-end collision.

[0004] Therefore, the prior art cannot balance the driving experience of the driver in the manual mode and the driving safety of the driver in the non-manual mode. SUMMARY

[0029] The example embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements, unless the context clearly shows otherwise. The following description of example embodiments is not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0030] The block diagrams shown in the drawings are merely functional entities, and do not necessarily have to correspond to physically independent entities. That is, the functional entities can be implemented in software, or in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0031] The flowcharts shown in the drawings are merely exemplary illustrations, and do not necessarily include all contents and operations / steps, nor do they have to be executed in the order described. For example, some operations / steps can be further divided, and some operations / steps can be combined or partially combined, so that the actual execution order can be changed depending on the actual situation.

[0032] It should also be noted that "a plurality of" as referred to in the present application means two or more. The association relationship of "and / or" describes the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone, these three cases. The character " / " generally means that the associated objects before and after are in an "or" relationship.

[0033] The terms "first," "second," "third," and "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. The terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0034] First, it should be noted that this application relates to the field of vehicle technology. A transmission is a drive system used in vehicles that automatically changes gears while the vehicle is in motion, without requiring the driver to manually operate the clutch and gear lever. A transmission includes a gear shift module (GSM), a transmission control unit (TCU), and an engine management system (EMS), which will be described in detail below.

[0035] The engine control system is a system used to control and manage the operation of a vehicle's engine. It is mainly responsible for monitoring and controlling various parameters of the vehicle's engine and sending the monitored parameters to the transmission control system. These parameters include engine speed, engine torque, and throttle opening, to ensure efficient engine operation, low emissions, and good performance.

[0036] The gear shift control system is the component responsible for actually executing the vehicle's gear shifting operations. It is mainly responsible for monitoring parameters such as the vehicle's current driving mode, gear lever mode, or steering wheel paddle shifters "+" and "-". When the driver performs the above operations, it can send the monitored parameters to the transmission control system.

[0037] The transmission control system is the core control unit of the transmission. It can receive various parameter information sent by the engine control system and the shift control system, and is responsible for monitoring and responding to the vehicle's driving conditions, making the vehicle's shifting process smoother and more efficient.

[0038] To enhance the driving experience, automakers typically equip vehicles with paddle shifters. When the driver manually shifts gears using the paddle shifters, the vehicle will either automatically upshift or maintain a higher engine speed while the transmission remains in the current gear (or locked).

[0039] However, since the current transmission control system only has one manual mode shift diagram, please refer to [link / reference needed]. Figure 1 As shown, Figure 1is a schematic diagram of the control logic of the current vehicle automatic upshift or lock shift. As shown in Figure 1 in the manual mode and the non-manual mode, only one of the automatic upshift or no automatic upshift (i.e. lock shift) logic can be selected, wherein the non-manual mode includes the comfort mode, the economy mode, the sports mode, the race mode and other modes. If the automatic upshift logic is selected in the manual mode, the automatic upshift at full throttle can be performed according to the preset calibration threshold, but the driver cannot perform the upshift operation autonomously, which greatly reduces the driver's pleasure and passion. If the no automatic upshift logic is selected in the non-manual mode, the automatic upshift at full throttle of the gearbox is prohibited according to the preset calibration threshold, which will reduce the lap time of the driver on the track; at the same time, it is impossible to complete the overtaking by increasing the speed through upshift, which will cause the car owner to panic to some extent, and it is easy to cause the rear vehicle to rear-end.

[0040] Therefore, the prior art cannot balance the driving experience of the driver in the manual mode and the driving safety of the driver in the non-manual mode.

[0041] In order to solve the above technical problems, the present application proposes a transmission gear control method and device, electronic equipment and computer readable storage medium, which will be described in detail below.

[0042] Please refer to Figure 2 , Figure 2 is a schematic diagram of the vehicle architecture according to an example embodiment of the present application. As shown in Figure 2 , the vehicle architecture can include an engine 210, a gearbox 220, a hydraulic torque converter 230, a drive shaft 240, a throttle pedal 250, a lock-up clutch 260 and a gear shifter control system 270. The engine 210 and the gearbox 220 are connected through the hydraulic torque converter 230, and the lock-up clutch 260 is included in the hydraulic torque converter 230. The hydraulic torque converter 230 contains fuel, and the amount of fuel contained can affect the opening and closing of the lock-up clutch 260 therein. The drive shaft 240 is connected to the engine 220, and the throttle pedal 250 is also connected to the engine 210. When the throttle pedal 250 is depressed, the speed of the engine 210 will be increased.

[0043] Further, please refer to Figure 3 , Figure 3 is a schematic diagram of the internal structure of the vehicle according to an example embodiment of the present application. As shown in Figure 3As shown, the internal structure of the vehicle includes a steering wheel 310, a brake pedal 320, an accelerator pedal 330, and a gear lever 340. The steering wheel 310 is a component for controlling the driving direction of the vehicle, and the driver can control the steering of the vehicle by rotating the steering wheel 310. A steering wheel shift tab is arranged at the rear end of the left and right sides of the steering wheel 310, and the shift tab arranged on the left side is usually used to reduce the gear of the vehicle, and the shift tab arranged on the right side is usually used to increase the gear of the vehicle. The brake pedal 320 is a pedal for controlling the brake system of the vehicle, and the driver can slow down or stop the vehicle by stepping on the brake pedal 320. The accelerator pedal 330 is a pedal for controlling the acceleration of the vehicle, and the driver can increase the speed of the vehicle by stepping on the accelerator pedal 330. The accelerator pedal 330 is usually located on the right side of the brake pedal 320. The gear lever 340 is usually located on the central console in front of the driver's seat, and is a lever-shaped component for manually operating the transmission of the vehicle. The driver can select different driving gears by moving the gear lever 340.

[0044] Figure 4 is a flow chart of the transmission gear control method shown in an example embodiment of the present application. As shown in Figure 4 an example embodiment, the shift map provided in the transmission control system of the vehicle includes a manual mode shift map and a non-manual mode shift map, the method can include S410 to S440, and the execution subject of the embodiment of the present application can be the transmission control system. Wherein S410 to S440 are described in detail as follows:

[0045] S410: Obtain the current gear lever mode of the vehicle and / or the position change of the steering wheel shift tab, as well as the current engine speed and the accelerator opening degree.

[0046] The parameter information corresponding to the shifters of the vehicle is collected by the shifter control system and sent to the transmission control system. The parameter information corresponding to the engine of the vehicle is collected by the engine control system and sent to the transmission control system.

[0047] Specifically, please refer to Figure 5 , Figure 5 is a timing flow chart of the transmission gear control shown in an example embodiment of the present application. The shifter control system sends the parameter information corresponding to the shifters to the CAN bus, the shifters including the gear lever and the steering wheel shift tab, and the transmission control system receives the operating parameters corresponding to the shifters from the CAN bus. The engine control system sends the parameter information corresponding to the engine to the CAN bus, and the transmission control system receives the parameter information corresponding to the engine from the CAN bus.

[0048] In the embodiments of the present application, the parameter information corresponding to the gear selector can include a driving mode, a gear lever mode and a manual gear shift. The driving mode includes a non-manual mode and a manual mode, and the manual mode is further divided into a long-term manual mode and a short-term manual mode. The gear lever mode is divided into a P gear, an R gear, an N gear, a D gear and an M gear. Specifically, the P gear is a gear for parking the vehicle at a stationary position, when the vehicle is in the P gear, the transmission will lock the drive wheels to prevent the vehicle from rolling; the R gear is a gear for reversing, which is usually used to back out of a parking space or parking area; the N gear is a gear without driving force transmitted to the wheels, which is usually used for towing or traction; the D gear is a driving gear, the vehicle can move forward and the transmission will automatically select the appropriate gear to adapt to the driving conditions; the M gear is a manual mode, the driver can manually select the gear of the transmission. The manual gear shift includes the position change of the steering wheel gear shift paddle and the position change of the gear lever in the manual driving mode. The position change of the steering wheel gear shift paddle includes shifting the steering wheel gear shift paddle to upshift and shifting the steering wheel gear shift paddle to downshift. The position change of the gear lever in the manual driving mode includes pushing the gear lever to M+ to upshift and pushing the gear lever to M- to downshift.

[0049] The parameter information corresponding to the engine can include an accelerator opening degree (unit: %), an engine torque (unit: N·m), an engine speed (unit: rpm / min) and a vehicle speed (unit: km / h). The accelerator opening degree represents the proportion of the accelerator pedal being depressed, for example, the accelerator pedal is depressed by 1 / 4, the accelerator opening degree value is 25%; for another example, the accelerator pedal is depressed by 1 / 2, the accelerator opening degree value is 50%. The engine torque is the moment of the mechanical element rotating, also called the rotating moment or torque, and the engine torque of the vehicle can be obtained by the engine control system. The engine speed is the number of revolutions per minute of the engine crankshaft or flywheel end.

[0050] In the foregoing embodiments of the present application, the parameter information of the vehicle can include but is not limited to the above-mentioned various parameters, and the skilled in the art can add or delete the parameter information of the vehicle according to the actual situation, which is not limited in the embodiments of the present application.

[0051] S420: determining the driving mode of the vehicle according to the gear lever mode and / or the position change of the steering wheel gear shift paddle.

[0052] It should be noted that only when the gear lever mode is in the driving gear or the manual gear, the vehicle has the corresponding driving mode, and then the driving mode of the vehicle needs to be distinguished. The driving mode of the vehicle includes a non-manual mode and a manual mode, and the manual mode is further divided into a long-term manual mode and a short-term manual mode.

[0053] Specifically, if the current gear lever mode of the vehicle is drive mode, and the position of the steering wheel shift paddle does not change, it is determined that the current driving mode of the vehicle is non-manual mode.

[0054] If the current gear lever mode of the vehicle is manual mode, it is determined that the current driving mode of the vehicle is long-term manual mode; if the current gear lever mode of the vehicle is drive mode, and the position of the steering wheel shift paddle changes, it is determined that the current driving mode of the vehicle is short-term manual mode.

[0055] Whether the position of the steering wheel shift paddle changes depends on whether the driver moves the steering wheel shift paddle during the driving of the vehicle. If the driver moves the steering wheel shift paddle, the position of the steering wheel shift paddle changes; if the driver does not move the steering wheel shift paddle, the position of the steering wheel shift paddle does not change.

[0056] S430: If the driving mode is non-manual mode, determine the target engine speed corresponding to the throttle opening according to the non-manual mode shift map, and control the vehicle to execute the automatic upshift logic based on the target engine speed and the current engine speed.

[0057] Please refer to Figure 6 , Figure 6 is a schematic diagram of the control logic of the vehicle automatic upshift or lockout shown in an exemplary embodiment of the present application. The transmission control system selects the corresponding shift map according to the determined current driving mode. If the current driving mode is non-manual mode, the non-manual mode shift map, also known as Tip-in D shift map, is selected; if the current driving mode is manual mode, the manual mode shift map is selected. Moreover, both the non-manual mode shift map and the manual mode shift map include automatic upshift logic and lockout logic.

[0058] Both the non-manual mode shift map and the manual mode shift map include the corresponding relationship between the throttle opening and the engine speed of the vehicle, and the throttle opening determined by the vehicle has a unique corresponding engine speed. For example, when the throttle opening is 10%, the current engine speed is 1000 rpm / min; when the throttle opening is 20%, the current engine speed is 2000 rpm / min.

[0059] Specifically, the step of controlling the vehicle to execute the automatic upshift logic based on the target engine speed and the current engine speed includes:

[0060] Obtaining a plurality of gears of the vehicle and target engine speeds corresponding to the plurality of gears;

[0061] Determining the current gear of the vehicle according to the current engine speed of the vehicle;

[0062] If the vehicle increases the current engine speed so as to reach above the target engine speed corresponding to the next gear, the gear of the vehicle is automatically upshifted to the next gear.

[0063] The three steps are described in detail as follows.

[0064] The target engine speeds corresponding to the plurality of gears of the vehicle are predetermined in the non-manual mode shift map, for example, the target engine speed corresponding to gear 1 of the vehicle can be set as 2000 rpm / min, the target engine speed corresponding to gear 2 of the vehicle can be set as 2500 rpm / min, and each gear has a unique target engine speed. It can be seen that if the current engine speed of the vehicle is within 2000 rpm / min, it indicates that the vehicle is in gear 1; if the current engine speed of the vehicle is between 2000 rpm / min and 2500 rpm / min, it indicates that the vehicle is in gear 2.

[0065] For example, if the current engine speed of the vehicle is 1000 rpm / min, it can be determined that the current gear of the vehicle is gear 1; by increasing the current engine speed of the vehicle so as to reach above the target engine speed 2000 rpm / min corresponding to gear 1, the gear of the vehicle is automatically upshifted to gear 2. Similarly, if the current engine speed of the vehicle is 2100 rpm / min, it can be determined that the current gear of the vehicle is gear 2; by increasing the current engine speed of the vehicle so as to reach above the target engine speed 2500 rpm / min corresponding to gear 2, the gear of the vehicle is automatically upshifted to gear 3.

[0066] In another exemplary embodiment, since the accelerator opening degree of the vehicle corresponds to a unique engine speed, there is also a unique corresponding vehicle speed. For example, 70 km / h can be set as the target vehicle speed corresponding to gear 1, and 100 km / h can be set as the target vehicle speed corresponding to gear 2. It can be seen that if the current vehicle speed of the vehicle is within 70 km / h, it indicates that the vehicle is in gear 1; if the current vehicle speed of the vehicle is between 70 km / h and 100 km / h, it indicates that the vehicle is in gear 2.

[0067] For example, if the current vehicle speed of the vehicle is 60 km / h, it can be determined that the current gear of the vehicle is gear 1; by increasing the vehicle speed so as to reach above the target vehicle speed 70 km / h corresponding to gear 1, the gear of the vehicle is automatically upshifted to gear 2. Similarly, if the current vehicle speed of the vehicle is 80 km / h, it can be determined that the current gear of the vehicle is gear 2; by increasing the vehicle speed so as to reach above the target vehicle speed 100 km / h corresponding to gear 2, the gear of the vehicle is automatically upshifted to gear 3.

[0068] S440: If the driving mode is the manual mode, determining a calibration speed threshold according to the manual mode shift map, and controlling the vehicle to perform the lock shift logic based on the calibration speed threshold and the current engine speed.

[0069] The calibration speed threshold is preset in the manual mode shift map, and is an engine speed threshold for determining whether the vehicle can perform the automatic upshift logic. If the current engine speed of the vehicle is below the engine speed threshold, the vehicle cannot perform the automatic upshift logic and can only perform the lock shift logic. If the current engine speed of the vehicle is above the engine speed threshold, the vehicle can perform the automatic upshift logic.

[0070] In order to ensure that the vehicle can only perform the lock shift logic in the manual mode, the calibration speed threshold is set to an engine speed that cannot be reached in normal driving conditions, for example, 8000 rpm / min, 9000 rpm / min, etc. Similarly, an unreachable vehicle speed threshold can also be set, for example, 300 km / h, 400 km / h, etc. That is, if the vehicle speed is below the vehicle speed threshold, the vehicle cannot perform the automatic upshift logic and can only perform the lock shift logic. If the vehicle speed is above the vehicle speed threshold, the vehicle can perform the automatic upshift logic.

[0071] Since the vehicle can only perform the lock shift logic, manual operation by the driver is required when upshifting or downshifting. If the vehicle is in long-term manual mode, the vehicle can be upshifted or downshifted according to the control operation triggered by the gear lever of the vehicle, and the vehicle can also be upshifted or downshifted according to the control operation triggered by the steering wheel shift paddle. If the vehicle is in short-term manual mode, the vehicle can only be upshifted or downshifted according to the control operation triggered by the steering wheel shift paddle.

[0072] By this method, a non-manual mode shift map is added to the transmission control system of the vehicle, so that the transmission control system of the vehicle includes a manual mode shift map and a non-manual mode shift map. By obtaining the current gear lever mode of the vehicle and / or the position change of the steering wheel shift paddle, the driving mode of the vehicle is determined. If it is determined that the vehicle is in a non-manual driving mode, the target engine speed corresponding to the throttle opening is determined according to the non-manual mode shift map, and the vehicle is controlled to perform the automatic upshift logic based on the target engine speed and the current engine speed, thereby preventing the driver's driving safety from being threatened due to the vehicle's inability to continuously accelerate. If it is determined that the vehicle is in a manual driving mode, a calibration speed threshold is determined according to the manual mode shift map, and the vehicle is controlled to perform the lock shift logic based on the calibration speed threshold and the current engine speed, thereby requiring the driver to manually shift gears and ensuring the driver's driving experience.

[0073] Therefore, the technical scheme provided by the application can balance the driving experience of the driver in the manual mode and the driving safety of the driver in the non-manual mode.

[0079] In an embodiment of the application, based on the foregoing scheme, the driving mode determination module 720 further includes a long-term manual mode determination unit and a short-term manual mode determination unit. The long-term manual mode determination unit is configured to determine the driving mode as the long-term manual mode if the current gear lever mode is the manual gear. The short-term manual mode determination unit is configured to determine the driving mode as the short-term manual mode if the current gear lever mode is the drive gear and the position of the steering wheel shift paddle changes.

[0080] In an embodiment of the application, based on the foregoing scheme, the lock gear logic execution module 740 further includes a lock gear logic determination unit and a lock gear logic execution unit.
