[0038] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Currently, in dual clutch transmission shift control, if the torque capacity of the in-gear clutch is too large and the out-gear clutch has torque holding capability, clutch disengagement will occur. If the clutch is released too early and the in-gear clutch does not have enough torque capacity to hold the engine torque at that time, engine knock will occur. Therefore, in order to meet the given shift requirements, it is crucial to precisely control the transmission torque and torque capacity of each clutch.

[0040] In the related art, fixed shifting requirements and control logic are often used in the shifting control of the dual-clutch transmission. That is, when shifting gears in this shifting control scheme, it is impossible to dynamically adjust the user's needs between the shifting speed and the shifting smoothness. As a result, in the user's actual driving scenario, the user's desire to shift gears as quickly as possible cannot be met, which needs to be further improved.

[0041] Based on the above problems, the present application proposes a dual-clutch power system torque control method, device, equipment and storage medium. The key point of the invention is that by determining the expected indicators between shifting smoothness and shifting speed required by the current vehicle according to the current shifting mode of the user's vehicle, the shifting scheme of the first clutch, the second clutch and the engine can be calculated according to the expected indicators, so that the expected indicators under the current shifting mode can be met during gear shifting, that is, the fastest shifting speed can be achieved while satisfying the set gear shifting smoothness, and ultimately, the user can be guaranteed to shift gears smoothly.

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0043] In a first aspect, an embodiment of the present application provides a torque control method for a dual-clutch powertrain.

[0044] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the torque control method of the dual-clutch power system of the present application. Figure 1 As shown, the dual-clutch power system torque control method includes:

[0045] S100, responding to a shift signal, determining expected indicators of shifting smoothness and shifting speed in a set shifting mode of a dual-clutch power system according to the shifting mode; wherein the shifting smoothness and the shifting speed are negatively correlated among the different expected indicators;

[0046] S200. Determine, based on the expected index, a shifting scheme for the first clutch, the second clutch, and the engine that each satisfies the expected index.

[0047] In this embodiment, the expected index required by the current vehicle between the gear shifting smoothness and the gear shifting speed is determined according to the gear shifting mode that the current user's vehicle is in. The gear shifting scheme of the first clutch, the second clutch and the engine can be calculated according to the expected index, so that the expected index under the current gear shifting mode can be met when shifting. Exemplarily, when the vehicle is set to the first gear shifting mode, it is required to meet the minimum stability index while achieving the fastest gear shifting speed that can be achieved. At this time, the expected index can be used to adjust the relevant parameters of the first clutch, the second clutch and the engine during the gear shifting process, such as torque, pressure applied to the clutch and other parameters, to achieve the expected index. Finally, it is ensured that the vehicle can shift gears in different gear shifting methods according to the current gear shifting mode of the vehicle, thereby meeting the user's gear shifting needs in different scenarios.

[0048] Further, the step S200, determining, according to the expected index, a shifting scheme in which the first clutch, the second clutch, and the engine each meet the expected index, comprises the following steps:

[0049] S210, obtaining a transmission shaft transmission ratio of the first clutch, a reduction gear ratio of the first clutch, a transmission shaft transmission ratio of the second clutch, and a reduction gear ratio of the second clutch;

[0050] S220, determining output torques of the first clutch, the second clutch, and the engine that meet the expected index, based on the transmission shaft transmission ratio of the first clutch, the reduction gear ratio of the first clutch, the transmission shaft transmission ratio of the second clutch, the reduction gear ratio of the second clutch, and the expected index;

[0051] S230: Determine a shifting scheme according to the output torques of the first clutch, the second clutch and the engine, respectively.

[0052] With this arrangement, it is possible to calculate the output torques required by the first clutch, the second clutch and the engine to meet the current expected indicators based on the transmission shaft ratio of the first clutch, the reduction gear ratio of the first clutch, the transmission shaft ratio of the second clutch and the reduction gear ratio of the second clutch, and then further determine and apply other related parameters based on these output torques.

[0053] Specifically, in this embodiment, step S220 determines the output torques of the first clutch, the second clutch and the engine that meet the expected index, based on the transmission shaft transmission ratio of the first clutch, the reduction gear ratio of the first clutch, the transmission shaft transmission ratio of the second clutch, the reduction gear ratio of the second clutch and the expected index, using the following calculation formula:

[0054]

[0055] In the formula, is the expected indicator, i t1 is the transmission shaft ratio of the first clutch, i f1 is the reduction gear ratio of the first clutch, i t2 is the transmission shaft ratio of the second clutch, i f2 is the reduction gear ratio of the second clutch, J e+d is the inertia of the engine and dual-mass flywheel, J ct2 is the inertia of the second clutch output shaft, T c1 is the output torque of the first clutch, T c2 is the output torque of the second clutch, T e is the output torque of the engine.

[0056] Further, in one embodiment, the S230, determining the shifting scheme according to the output torques of the first clutch, the second clutch and the engine, comprises the following steps:

[0057] S231, obtaining a first pressure required by the first clutch and a second pressure required by the second clutch according to output torques of the first clutch and the second clutch;

[0058] S232. Adjust the current required by the motor according to the first pressure and the second pressure.

[0059] Specifically, in adjusting the motor current according to the first pressure and the second pressure, a preset reverse force displacement map is transmitted to the motor position controller to adjust the current required by the motor.

[0060] In this embodiment, after the required pressure is calculated according to the output torque of the first clutch and the second clutch, it is transmitted to the motor position controller through the reverse force displacement map to adjust the required current, thereby feeding back the energy of the entire power system.

[0061] Further, in one embodiment, in S100, in response to the shift signal, according to the set shift mode of the dual-clutch power system, determining the expected indexes of the shift smoothness requirement and the shift speed in the shift mode,

[0062] S110, determining the expected index corresponding to the preset shift mode according to the correspondence between a preset fast shift mode, a smooth shift mode, and a plurality of optional shift modes between the fast shift mode and the smooth shift mode and a plurality of expected indexes.

[0063] In this embodiment, by establishing in advance the correspondence between multiple optional shift modes including a fast shift mode and a smooth shift mode and multiple expected indicators, it is achieved that when the vehicle is in a certain shift mode, it can quickly correspond according to the established expected indicators, and then determine clear expected indicators to perform the next shift operation.

[0064] In other embodiments, responding to the shift signal and determining the expected indexes of the shift smoothness requirement and the shift speed in the shift mode according to the set shift mode of the dual-clutch power system comprises the following steps:

[0065] S120, obtaining a mode position of a shift mode of a set dual-clutch power system between a preset fast shift mode and a smooth shift mode;

[0066] S121. Determine the corresponding expected index within a preset index range according to the mode position; wherein the two ends of the index range correspond to the fast shift mode and the smooth shift mode respectively.

[0067] This setting allows customers to more independently choose expected indicators between smooth shifting mode and fast shifting mode, and not be restricted to a few fixed shifting modes. After determining a shifting mode according to their own needs, they can calculate the expected indicators that best meet current needs, and use the expected indicators for subsequent shifting operations, further ensuring that the overall driving experience of users when performing shifting operations can be smoothly synchronized with their own needs.

[0071] The shift module is configured to determine, based on the expected index, a shift scheme in which the first clutch, the second clutch, and the engine each meet the expected index.
