[0049] Those skilled in the art can understand that Figure 1 the structure shown in does not constitute a limitation on the electric dual-clutch control device, and it may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0051] In Figure 1 the electric dual-clutch control device shown in the figure, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the electric dual-clutch control device of the present invention may be arranged in the electric dual-clutch control device. The electric dual-clutch control device calls the electric dual-clutch control program stored in the memory 1005 through the processor 1001 and executes the electric dual-clutch control method provided by the embodiments of the present invention.

[0052] The embodiments of the present invention provide an electric dual-clutch control method. Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of an electric dual-clutch control method of the present invention.

[0053] In this embodiment, the electric dual-clutch control method includes the following steps:

[0054] Step S10: Obtain the current working state of the electric-execution dual clutch.

[0055] It should be understood that the execution subject of the method in this embodiment can be an electric-execution dual clutch control device with data processing, network communication, and program running functions, such as an in-vehicle controller, etc., or other devices or equipment that can achieve the same or similar functions. Here, the above-mentioned electric-execution dual clutch control device (hereinafter referred to as the clutch control device) is taken as an example for illustration.

[0056] It should be noted that the electric-execution dual clutch can be a dual clutch driven by a motor, where the dual clutch includes an odd clutch and an even clutch. The above odd clutch can be a clutch that controls odd gears, and the above even clutch can be a clutch that controls even gears. The above current working state can be the current running working state of the electric-execution dual clutch. For example, the current working state can be the clutch stationary state, the clutch pre-charging state, the clutch torque rising state, and the clutch torque falling state, etc.

[0057] Step S20: Determine the duty ratio of the drive motor corresponding to the electric-execution dual clutch according to the current working state.

[0058] It should be noted that the drive motor can be a motor that drives the electric-execution dual clutch. The above duty ratio can be the proportion of the energization time of the drive motor corresponding to the electric-execution dual clutch in a pulse cycle to the total time.

[0059] It should be understood that in order to accurately control the drive motor corresponding to the electric-execution clutch according to the current working state of the electric-execution dual clutch, the clutch control device in this embodiment controls the drive motor corresponding to the odd clutch and the drive motor corresponding to the even clutch in the electric-execution dual clutch respectively according to the duty ratio, so that the drive motor drives the electric-execution dual clutch.

[0060] In specific implementation, the clutch control device identifies the current working state of the electric-execution dual clutch, determines the duty ratio of the drive motor corresponding to the electric-execution dual clutch according to the current working state, and determines the energization time of the drive motor in a pulse cycle according to the duty ratio.

[0061] Further, in order to accelerate the rate of the motor from stationary to starting to move, the above step S20 may include:

[0062] When the current working state is the stationary state, determine the position difference between the target position and the current position according to the position comparison result;

[0063] When the position difference exceeds the first preset threshold, determine the duty ratio of the drive motor corresponding to the electric-execution dual clutch according to the position difference and the stationary state.

[0064] It should be noted that the current working state may include states such as a stationary state, a pre-charge state, a torque rising state, and a torque falling state. The above position difference may be the difference between the current position and the target position.

[0065] It should be understood that in order to accelerate the rate of the motor from rest to starting to operate, when the current working state of the clutch control device in this embodiment is the stationary state, the position difference between the target position and the current position is determined according to the position comparison result. When the position difference exceeds a first preset threshold, the duty ratio of the drive motor corresponding to the electric-executed dual clutch is determined according to the position difference and the stationary state, and a given larger duty ratio is output for a certain period of time to enable the motor to quickly start from the stationary state.

[0066] Furthermore, in order to ensure the consistency of the pre-charge response of the electric-executed dual clutch, step S20 may include:

[0067] When the current working state is the pre-charge state, it is determined whether the target position is greater than the current position according to the position comparison result;

[0068] If so, the integral unit of the PID controller corresponding to the electric-executed dual clutch is cleared;

[0069] The PID controller is controlled to perform a feed-forward calculation, and the duty ratio of the drive motor corresponding to the electric-executed dual clutch is determined according to the calculation result.

[0070] It should be noted that the relevant parameters for the torque control of the electric-executed dual clutch should be able to adapt to different current working states. The Kp, Ki, Kd, and feed-forward term of the clutch position control can be obtained by looking up a preset mapping table according to the clutch target position, the difference between the clutch target position and the current position.

[0071] It should be understood that in order to ensure the consistency of the pre-charge response of the electric-executed dual clutch, when the current working state of the clutch control device in this embodiment is the pre-charge state, it is determined whether the target position is greater than the current position according to the position comparison result. If so, the integral unit of the PID controller corresponding to the electric-executed dual clutch is cleared, and the PID controller is controlled to perform a feed-forward calculation, and the duty ratio of the drive motor corresponding to the electric-executed dual clutch is determined according to the calculation result, thereby ensuring the consistency of the pre-charge response of the electric-executed dual clutch.

[0072] Furthermore, in order to improve the response speed of the electric-executed dual clutch during torque reduction, step S20 may include:

[0073] When the current working state is the torque decreasing state, determine whether the position difference between the target position and the current position exceeds a second preset threshold according to the position comparison result;

[0074] When the position difference does not exceed the second preset threshold, determine the running direction of the drive motor corresponding to the torque decreasing state;

[0075] Determine the duty ratio of the drive motor according to the running direction, the position difference, and the torque decreasing state.

[0076] It should be understood that, in order to improve the response speed of the electro - actuated dual clutch during torque decrease, the clutch control device in this embodiment determines whether the position difference between the target position and the current position exceeds a second preset threshold according to the position comparison result when the current working state is the torque decreasing state. When the position difference does not exceed the second preset threshold, determine the running direction of the drive motor corresponding to the torque decreasing state, and determine the duty ratio of the drive motor according to the running direction, the position difference, and the torque decreasing state, and output a given large reverse duty ratio for a certain period of time to achieve rapid commutation of the motor and improve the response speed of the clutch torque decrease.

[0077] Further, in order to improve the response speed of the running direction of the drive motor corresponding to the electro - actuated dual clutch, the above - mentioned step S20 may include:

[0078] When the signs of the proportional unit and the integral unit of the PID controller corresponding to the electro - actuated dual clutch are opposite, determine the position difference between the target position and the current position according to the position comparison result;

[0079] When the position difference exceeds a third preset threshold, clear the integral unit of the PID controller corresponding to the electro - actuated dual clutch.

[0080] It should be understood that, in order to improve the response speed of the running direction of the drive motor corresponding to the electro - actuated dual clutch, the clutch control device in this embodiment determines the position difference between the target position and the current position according to the position comparison result when the signs of the proportional unit and the integral unit of the PID controller corresponding to the electro - actuated dual clutch are opposite, and clears the integral unit of the PID controller corresponding to the electro - actuated dual clutch when the position difference exceeds a third preset threshold, avoiding that the integral unit cannot calculate the correct sign as soon as possible during steering, thereby improving the response speed of the running direction of the drive motor corresponding to the electro - actuated dual clutch.

[0081] Step S30: Control the drive motor to drive the odd - numbered clutch and the even - numbered clutch in the electro - actuated dual clutch according to the duty ratio.

[0082] It should be noted that the clutch control device can determine the proportion of the energization time of the drive motor within a pulse cycle relative to the total time according to the duty ratio, and control the energization of the drive motor according to the duty ratio.

[0083] In this embodiment, by obtaining the current working state of the electro-executed dual clutch, determining the duty ratio of the drive motor corresponding to the electro-executed dual clutch according to the current working state, and controlling the drive motor to drive the odd clutch and the even clutch in the electro-executed dual clutch according to the duty ratio. The present invention determines the duty ratio of the drive motor according to the current working state of the electro-executed dual clutch, and controls the drive motor according to the duty ratio, so that the drive motor drives the odd clutch and the even clutch in the electro-executed dual clutch respectively, thereby realizing precise control of the electro-executed dual clutch, improving the control accuracy of the electro-executed clutch, and effectively improving the performance of the electro-executed clutch.

[0084] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of a method for controlling an electro-executed dual clutch according to the present invention.

[0085] Based on the above first embodiment, in this embodiment, the step S10 includes:

[0086] Step S101: Obtain the motor state of the drive motor corresponding to the electro-executed dual clutch.

[0087] It should be noted that the motor state can be the operating state of the motor. For example, the motor state can be states such as the motor stationary state, the motor running state, and the motor pre-charging state.

[0088] Step S102: Determine the position information of the electro-executed dual clutch according to the motor state.

[0089] It should be noted that the position information can be the target position information and the current position information of the electro-executed dual clutch. The clutch control device can determine the current working state of the electro-executed dual clutch according to the position information of the electro-executed dual clutch and the motor state of the drive motor.

[0090] In a specific implementation, the clutch control device can determine the current position and the target position of the electro-executed dual clutch according to the position information of the electro-executed dual clutch, compare the current position and the target position, determine the position difference according to the comparison result, and determine the current working state of the electro-executed dual clutch according to the position difference and the motor state.

[0091] For example, the clutch control device recognizes that the drive motor is currently in a stationary state, compares the current position with the target position, determines the position difference based on the comparison result, and when it determines that the position difference between the target position and the current position of the electro-executed dual clutch is greater than a preset threshold, the clutch control device determines that the current working state of the electro-executed dual clutch is the stationary state.

[0092] Step S103: Determine the current working state of the electro-executed dual clutch according to the motor state and the position information.

[0093] It should be noted that the current working state can be the current operating working state of the electro-executed dual clutch. For example, the current working state can be the clutch stationary state, the clutch pre-charge state, the clutch torque rising state, and the clutch torque falling state, etc.

[0094] In a specific implementation, the clutch control device determines the current working state of the electro-executed dual clutch according to the position information of the electro-executed dual clutch and the motor state of the drive motor, so as to accurately identify the current working state of the electro-executed dual clutch, thereby achieving precise control of the electro-executed dual clutch.

[0095] For example, the clutch control device recognizes that the drive motor is currently in a stationary state, compares the current position with the target position, determines the position difference based on the comparison result, and when it determines that the position difference between the target position and the current position of the electro-executed dual clutch is greater than a preset threshold, the clutch control device determines that the current working state of the electro-executed dual clutch is the stationary state.

[0096] For example, the clutch control device recognizes that the target position of the electro-executed dual clutch is the pre-charge point and the target position of the electro-executed dual clutch is greater than the current position, and the clutch control device determines that the current working state of the electro-executed dual clutch is the pre-charge state.

[0097] For example, the clutch control device recognizes that the drive motor is currently in an operating state, and the position difference between the target position and the current position of the electro-executed dual clutch is less than a preset threshold, and the clutch control device determines that the current working state of the electro-executed dual clutch is the torque falling state.

[0098] Furthermore, in order to accurately identify the current working state of the electro-executed dual clutch, the above step S103 includes:

[0099] Step S1031: Compare the target position with the current position to obtain a position comparison result;

[0100] Step S1032: Determine the current working state of the electro-executed dual clutch according to the motor state and the position comparison result.

[0101] It should be noted that the position comparison result can be the result of the comparison between the target position and the current position of the electrically actuated dual clutch. For example, the position comparison result can be whether the target position is greater than the current position, whether the target position is less than the current position, and the difference between the target position and the current position, etc.

[0102] In this embodiment, the motor state of the drive motor corresponding to the electrically actuated dual clutch is obtained; the position information of the electrically actuated dual clutch is determined according to the motor state; and the current working state of the electrically actuated dual clutch is determined according to the motor state and the position information. Since the present invention determines the current working state of the electrically actuated dual clutch according to the position information of the electrically actuated dual clutch and the motor state of the drive motor, the accurate identification of the current working state of the electrically actuated dual clutch is realized.

[0103] In addition, an embodiment of the present invention also provides a storage medium, on which an electrically actuated dual clutch control program is stored. When the electrically actuated dual clutch control program is executed by a processor, the steps of the electrically actuated dual clutch control method as described above are realized.
