Description

Technical Field

[0001] The present application relates to the technical field of automobile transmission shifting, and in particular to a shifting control method, device, equipment and readable storage medium of an AMT transmission. Background Art

[0002] At present, the existing AMT shifting method is mainly to shift according to the engine speed range, and at the same time, the shifting speed is corrected in combination with the throttle opening and the road slope. The main implementation method is to write the engine shifting speed range corresponding to different gears in the gearbox shifting logic. During the gear shifting, when the engine is within the current speed range, the gearbox does not take the gear shifting action. When the engine speed is higher than the set value, the gearbox takes the upshift action, and when the engine speed is lower than the set value, it takes the downshift action. This is also the most widely used shifting method.

[0003] However, the above gearbox shifting logic mainly uses the engine speed as the main gear shifting judgment condition, and corrects the speed based on the slope and throttle opening. This shifting control method results in the engine speed being in the non-shifting range under high-speed and low-torque conditions, and the gearbox cannot adjust the gear in time, so the engine will run in the non-economical area, affecting the economy of the engine.

In addition, these processes may include more or fewer operations, and these operations or steps may be executed in sequence or in parallel, and these operations or steps may be combined.

[0045] At present, the existing AMT shifting method is mainly to shift according to the engine speed range, and at the same time, the shifting speed is corrected in combination with the throttle opening and the road slope. The main implementation method is to write the engine shifting speed range corresponding to different gears in the gearbox shifting logic. During the gear shifting, when the engine is within the current speed range, the gearbox does not take the gear shifting action. When the engine speed is higher than the set value, the gearbox takes the upshift action, and when the engine speed is lower than the set value, it takes the downshift action. This is also the most widely used shifting method.

[0046] However, the above gearbox shifting logic mainly uses the engine speed as the main gear shifting judgment condition, and corrects the speed based on the slope and throttle opening. This shifting control method results in the engine speed being in the non-shifting range under high-speed and low-torque conditions, and the gearbox cannot adjust the gear in time, so the engine will run in the non-economical area, affecting the economy of the engine.

[0047] Based on the above problems, the embodiments of the present application provide a shift control method, device, equipment and readable storage medium for an AMT transmission. The key point of the invention is that the actual fuel consumption parameters of the current vehicle gear are calculated by obtaining the engine speed and engine torque of the vehicle in driving state, and further the calculation of simulated fuel consumption parameters is performed in other gears that meet the current driving speed, so as to obtain the fuel consumption economy of each gear that can be selected at the current driving speed, and select the gear with smaller fuel consumption parameter for switching, and finally control the vehicle to drive in a gear with better fuel consumption economy at this speed, thereby solving the technical problem of poor economy of the selected gear in the related technology.

[0048] In a first aspect, an embodiment of the present application provides a shift control method for an AMT transmission.

[0049] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the shift control method of the AMT transmission of the present application. Figure 1 As shown, the shift control method of the AMT transmission includes:

[0050] S100, obtaining the current vehicle speed, driving gear, engine speed, and engine torque;

[0051] S200, obtaining an actual fuel consumption parameter of the vehicle according to the engine speed and the engine torque;

[0052] S300, simulating and obtaining the simulated engine speed and simulated engine torque when the vehicle is traveling at the driving speed in one or more other gears, and obtaining the corresponding simulated fuel consumption parameters of the vehicle in each other gear;

[0053] S400, determining whether the simulated fuel consumption parameter is smaller than the actual fuel consumption parameter;

[0054] S500: If yes, according to whether the vehicle currently meets the set automatic shifting condition, adjust the driving gear of the vehicle to the gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter.

[0055] Specifically, when calculating the actual fuel consumption parameters in step S200, the two-dimensional coordinate correspondence table corresponding to the engine speed, engine torque and fuel consumption parameters that are collected and calculated in advance can be used to calculate and output the fuel consumption parameters corresponding to the current engine speed and engine torque in a two-dimensional interpolation manner. At the same time, in step S300, one or more other gears can be selected in different embodiments to simulate the calculation of fuel consumption parameters. It should be noted that the gears involved in the calculation need to be able to support the current driving speed. For gears that cannot support the current driving speed, there is no need to participate in the calculation and subsequent comparison. Finally, when it is found that there is a gear with lower fuel consumption, the gear can be switched to a gear with a lower fuel consumption parameter according to the set automatic shifting conditions.

[0056] Therefore, in this embodiment, the actual fuel consumption parameters of the current vehicle gear are calculated by obtaining the engine speed and engine torque of the vehicle in driving state, and the calculation of the fuel consumption parameters is further simulated in other gears that meet the current driving speed, so as to obtain the fuel consumption economy of each gear that can be selected at the current driving speed, and select the gear with smaller fuel consumption parameters for switching, and finally control the vehicle to drive in a gear with better fuel consumption economy at this speed, thereby solving the technical problem of poor economy of the selected gear in the related technology.

[0057] Further, in one embodiment, the step S300, simulating the engine speed and engine torque of the vehicle when it is traveling in one or more other gears that allow the driving speed, and obtaining the corresponding simulated fuel consumption parameters of the vehicle in each other gear, includes the following steps:

[0058] S310, simulating and obtaining the corresponding engine simulated speed and engine simulated torque when the vehicle is in the previous gear and the next gear of the driving gear at the driving speed;

[0059] S320. Calculate, based on the corresponding simulated engine speed and simulated engine torque, a first simulated fuel consumption parameter and a second simulated fuel consumption parameter corresponding to the vehicle in the previous gear and the next gear of the driving gear, respectively.

[0060] In this embodiment, by comparing the previous gear and the next gear of the current driving gear, it is effectively ensured that the gear for simulation calculation meets the current driving speed requirement. At the same time, by calculating the fuel consumption of both the higher speed gear and the lower speed gear relative to the current driving gear, it is possible to find a gear with more suitable fuel consumption parameters more comprehensively. In addition, the analysis and calculation of two adjacent gears makes the subsequent gear switching smoother and more reliable.

[0061] Further, in one embodiment, the step S500, according to whether the vehicle currently meets the set automatic shifting condition, adjusts the driving gear of the vehicle to the gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter,

[0062] Adjust the driving gear of the vehicle to the gear corresponding to the minimum simulated fuel consumption parameter.

[0063] In this embodiment, by adjusting the gear to the gear corresponding to the smallest simulated fuel consumption parameter, the lowest fuel consumption effect can be achieved at the current driving speed, thereby fully solving the problem of poor fuel consumption economy of the gear selected by the vehicle during driving in related technologies.

[0064] Further, in another embodiment, the step S500, according to whether the vehicle currently meets the set automatic shifting condition, adjusts the vehicle's driving gear to a gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter,

[0065] The driving gear of the vehicle is adjusted to a gear whose median vehicle speed is closest to the driving speed among the gears corresponding to the simulated fuel consumption parameters that are smaller than the actual fuel consumption parameters.

[0066] In this embodiment, the vehicle's driving gear is adjusted to a gear corresponding to a plurality of simulated fuel consumption parameters that are smaller than the actual fuel consumption parameters, and the gear whose median speed is closest to the driving speed, so that the fuel consumption can be reduced to a certain extent after the gear adjustment, thereby improving the economy. At the same time, it can ensure that the vehicle is in a relatively suitable gear at the current driving speed, avoiding frequent gear switching after a small change in the driving speed, which affects the normal driving of the vehicle.

[0067] Further, in some embodiments, the step S500, adjusting the driving gear of the vehicle to a gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter according to whether the vehicle currently meets the set automatic shifting condition, includes the following steps:

[0068] S510, determining whether the vehicle is in a fuel consumption economy mode;

[0069] S520: If the vehicle is in a fuel economy mode, adjust the driving gear of the vehicle to a gear corresponding to the simulated fuel consumption parameter that is smaller than the actual fuel consumption parameter.

[0070] Specifically, in some embodiments, the fuel economy mode of the car is started or closed by a trigger switch. The trigger switch can be a physical switch set inside the vehicle or a data signal switch triggered on the driving computer. In other embodiments, the fuel economy mode is started or closed according to the road traffic conditions of the future set distance. Specifically, the road traffic conditions of the future set distance will be obtained from the map software carried by the driving computer, including subsequent road parameters, vehicle parameters on the road ahead, traffic light information, etc., so as to analyze the braking frequency and acceleration frequency on the future road. For sections with high braking and acceleration frequencies, it is not suitable to execute the fuel economy mode to avoid frequent gear shifting of the vehicle. For relatively stable future sections, it can be judged to execute the fuel economy mode, so that the vehicle can travel with better fuel economy in the subsequent stable operation process.

[0071] Further, in some embodiments, after the step S500, according to whether the vehicle currently meets the set automatic shifting condition, adjusting the driving gear of the vehicle to the gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter,

[0072] S600: If a brake or accelerator signal is obtained, adjust the driving gear of the vehicle to a gear whose median speed is closest to the driving speed.

[0073] In this embodiment, after switching to a gear with a lower fuel consumption parameter, although the gear can meet the current driving speed requirement, the degree of support based on the driving speed variation range will be relatively reduced. Therefore, when there are driving instructions such as brake or throttle signals that affect the rapid change of vehicle speed, in order to ensure that the vehicle can travel with better stability in the subsequent stage, this application first adjusts the vehicle gear to the gear whose median speed is closest to the driving speed.

[0074] In a second aspect, an embodiment of the present application also provides a shift control device for an AMT transmission.

[0075] In one embodiment, referring to Figure 2 , Figure 2 This is a functional module diagram of an embodiment of the shift control device of the AMT transmission of the present application. Figure 2 As shown, the shift control device of the AMT transmission includes:

[0078] The adjustment module is configured to determine whether the simulated fuel consumption parameter is smaller than the actual fuel consumption parameter; if so, based on whether the vehicle currently meets the set automatic shifting conditions, adjust the vehicle's driving gear to the gear corresponding to the simulated fuel consumption parameter that is smaller than the actual fuel consumption parameter.

[0079] Further, in one embodiment, when the calculation module simulates and obtains the simulated engine speed and the simulated engine torque when the vehicle is traveling at the driving speed in one or more other gears, and obtains the corresponding simulated fuel consumption parameters of the vehicle in each other gear, the calculation module includes the following steps:

[0080] Simulating and obtaining the corresponding engine simulated speed and engine simulated torque respectively when the vehicle is in the previous gear and the next gear of the driving gear at the driving speed;

[0081] According to the corresponding simulated engine speed and simulated engine torque, the first simulated fuel consumption parameter and the second simulated fuel consumption parameter corresponding to the vehicle in the previous gear and the next gear of the driving gear are calculated.

[0082] Furthermore, in one embodiment, when the adjustment module adjusts the vehicle's driving gear to a gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter according to whether the vehicle currently meets the set automatic gear shifting condition,

[0084] Furthermore, in one embodiment, when the adjustment module adjusts the vehicle's driving gear to a gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter according to whether the vehicle currently meets the set automatic gear shifting condition,

[0086] Further, in one embodiment, the adjustment module adjusts the vehicle's driving gear to a gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter according to whether the vehicle currently meets the set automatic shifting condition, including the following steps:

[0087] Determine whether the vehicle is in fuel economy mode;

[0088] If the vehicle is in a fuel economy mode, the driving gear of the vehicle is adjusted to a gear corresponding to the simulated fuel consumption parameter that is smaller than the actual fuel consumption parameter.

[0089] Furthermore, in one embodiment, a fuel consumption economy mode trigger module is also included, which is used to trigger and control the opening and closing of the fuel consumption economy mode. Specifically, the start or close can be controlled by a trigger switch connected to the fuel consumption economy mode trigger module, and / or the fuel consumption economy mode is started or closed according to the road traffic conditions of a set distance in the future.

[0090] Furthermore, in one embodiment, after the adjustment module adjusts the vehicle's driving gear to a gear corresponding to the simulated fuel consumption parameter that is less than the actual fuel consumption parameter according to whether the vehicle currently meets the set automatic shifting condition, it is further used to:

[0091] If a brake or accelerator signal is obtained, the driving gear of the vehicle is adjusted to a gear whose gear speed median is closest to the driving speed.
