Fig. 1 is a flowchart of a wet dual clutch transmission control method according to an embodiment of the present invention, which is applicable to a situation where a gear of a wet dual clutch transmission is flexibly controlled when a fastiff function of a vehicle is activated, and the method may be performed by a wet dual clutch transmission control device, which may be implemented in hardware and/or software, and the wet dual clutch transmission control device may be configured in the vehicle. As shown in fig. 1, the method includes:
s110, when the FASTOFF function of the target vehicle is in an activated state, determining whether a running gear of the wet type double clutch transmission of the target vehicle meets a preset control condition.
In the existing automatic gearbox control strategies, under the condition of quick throttle release, a vehicle activates Fastoff function by judging the throttle change slope, the throttle pedal opening and the like, and further the upshift of a transmission is forbidden, however, the control mode is too low in flexibility, and upshift cannot be performed under various working conditions such as a slope, a plateau and the like according to the driving intention of a driver, so that the driving experience of a user is influenced.

When the fact that the FASTOFF function activation flag bit FASTOFFLag is not equal to 1 is detected, the FASTOFF function is not activated, and gear shifting is carried out according to a normal gear shifting table; when the fastiff function activation flag fastiflag=1 is detected, the fastiff control strategy is activated.
The fastiff function activates the conditions of flag fastifffflag=1, including but not limited to the following conditions at the same time:
a) The gear shifting handle is not in a manual gear shifting mode;
b) The gear shifting handle is not at the P, R, N gear position;
c) The speed of the vehicle exceeds a certain threshold value FASTOFSPLimit, and the threshold value FASTOFSPLimit can be calibrated;

e) The accelerator pedal release speed is lower than a certain threshold fastoffDthLimit, which can be calibrated according to the driving mode;
f) The accelerator pedal release time does not exceed a certain threshold TimeFOfIdleDelay, which is calibrated according to the accelerator pedal release speed.
In the embodiment of the present invention, the control condition is that the driving gear is greater than 2.
When the current gear is smaller than 2, the driving gear is directly switched to 2 gears, and if the driving gear is 2 gears, the driving gear does not need to be switched.

and determining the current vehicle speed threshold according to the basic vehicle speed threshold and at least one compensation coefficient.
The current vehicle speed threshold value represents an upper limit value of a vehicle speed suitable for the target vehicle in a current vehicle state, and if the vehicle speed exceeds the current vehicle speed threshold value, the gear of the target vehicle needs to be switched to adapt to the vehicle speed.

and inputting the current driving mode and the driving gear into a first corresponding relation table to look up a table to obtain the basic vehicle speed threshold, wherein the first corresponding relation table comprises at least one driving mode and a corresponding relation between the driving gear and the basic vehicle speed threshold.
The driving mode includes, but is not limited to, economy mode, comfort mode, sport mode and the like, and can be freely selected by a driver according to driving habits and driving road conditions. For calculation of a basic vehicle speed threshold (SPH), a corresponding basic vehicle speed threshold is obtained by looking up a table according to a current driving mode of a target vehicle and a first correspondence table, and the first correspondence table can be calibrated according to actual requirements. For example, fig. 2 is a schematic diagram of a first correspondence table, as shown in fig. 2, according to an embodiment of the present invention, assuming that a current driving mode of a current target vehicle is a comfort mode and a gear is 3, a corresponding basic vehicle speed threshold is 40km/h.

and inputting the gradient interpolation and the driving gear into a second corresponding relation table to look up a table to obtain the gradient compensation coefficient, wherein the second corresponding relation table comprises at least one gradient interpolation and a corresponding relation between the driving gear and the gradient compensation coefficient.
The calculation of slope interpolation (slopeIndex) is performed, a table is checked according to a real-time slope signal (AXGradient) of a target vehicle, the real-time slope signal AXGradient is input, the slope interpolation slopeIndex is output, the corresponding relation can be determined according to actual requirements, and the real-time slope signal AXGradient can be obtained through sensing of a whole vehicle sensor of the vehicle. Fig. 3 is a schematic diagram of a table of correspondence between a real-time gradient signal and gradient interpolation according to an embodiment of the present invention, as shown in fig. 3, for example, when the real-time gradient signal is-10, the corresponding gradient interpolation is 8.
After gradient interpolation is obtained, the gradient interpolation and the driving gear are input into a second corresponding relation table, the corresponding gradient compensation coefficient is obtained by looking up a table, and the second corresponding relation table can be calibrated according to actual requirements. For example, fig. 4 is a schematic diagram of a second correspondence table according to an embodiment of the present invention, and as shown in fig. 4, assuming that the driving range is 3 and the gradient interpolation is 8, the gradient compensation coefficient is 0.75.
In an embodiment of the present invention, the compensation coefficient includes: a plateau compensation coefficient; correspondingly, determining the compensation coefficient of the target vehicle comprises:
obtaining corresponding air pressure interpolation according to the atmospheric pressure coefficient;
and inputting the air pressure interpolation and the driving gear into a third corresponding relation table to look up a table to obtain the altitude compensation coefficient, wherein the third corresponding relation table comprises at least one air pressure interpolation and a corresponding relation between the driving gear and the gradient compensation coefficient.
The method comprises the steps of calculating air pressure interpolation (AltIndex), and obtaining air pressure interpolation AltIndex corresponding to an air pressure coefficient according to a corresponding relation table of the air pressure coefficient LatitudeFac and the air pressure interpolation, wherein the air pressure coefficient LatitudeFac is the ratio of the current air pressure to the standard air pressure; the corresponding relation table of the atmospheric pressure system and the air pressure interpolation is input into an atmospheric pressure coefficient LatitudeFac, the air pressure interpolation AltIndex is output, and the corresponding relation table of the atmospheric pressure coefficient and the air pressure interpolation can be calibrated according to actual requirements. The barometric pressure coefficient LatitudeFac is typically measured by a sensor. Fig. 5 is a schematic diagram of a correspondence table between atmospheric pressure coefficient and air pressure interpolation according to an embodiment of the present invention, as shown in fig. 5, assuming that the atmospheric pressure coefficient LatitudeFac is 0.8, the corresponding air pressure interpolation AltIndex is 5.
After the air pressure interpolation is obtained, the air pressure interpolation and the driving gear are input into a third corresponding relation table, the corresponding altitude compensation coefficient is obtained by looking up a table, and the corresponding relation can be calibrated according to actual requirements. Fig. 6 is a schematic diagram of a third correspondence table according to an embodiment of the present invention, as shown in fig. 6, assuming that the air pressure interpolation is 5, the driving gear is 3, and the corresponding altitude compensation coefficient is 1.
In addition, when the vehicle is in a plain working condition, 1 can be directly used as a plateau compensation coefficient to indicate that no plateau compensation is needed.
After a basic vehicle speed threshold (SPH), a gradient compensation coefficient (m) and a plateau compensation coefficient (n) are obtained, a current vehicle speed threshold is obtained through the product SPH m n of the three.
And S130, controlling the driving gear according to the current vehicle speed threshold and the current vehicle speed of the target vehicle.
In an embodiment of the present invention, the controlling the driving gear according to the current vehicle speed threshold and the current vehicle speed of the target vehicle includes:
and when the current vehicle speed is greater than the current vehicle speed threshold value, executing an upshift operation.
When the current vehicle speed is detected to be greater than the basic vehicle speed threshold sph×m×n, executing step S301 to perform upshift, wherein the target gear=the current gear+1; when it is detected that the current vehicle speed is less than the basic vehicle speed threshold sph×m×n, step S302 is executed to maintain the current gear, and the target gear=the current gear.
The invention provides a gear shifting strategy under the condition of quick throttle release of a wet double-clutch automatic transmission, which solves the problems that after a FASTOFF function is activated in the condition of quick throttle release of a wet double-clutch automatic transmission vehicle, the vehicle is comprehensively judged to carry out adaptive upshift according to the road condition information such as the current driving mode, a slope, a plateau and the like, the gear shifting inhibiting function after throttle release can be controlled more flexibly, the upshift can be carried out more accurately according to the intention of a driver, and the frequent gear shifting of the vehicle can be effectively avoided.
