Description

Technical Field

[0001] The present invention relates to the field of computer technologies, and in particular, to a clutch control method, device, equipment, and computer-readable medium. Background Art

[0002] Currently, for vehicles with an automatic clutch control function, during the development stage, control parameters for clutch position requirements and control parameters for clutch speed requirements are usually pre-set in the starting clutch control program. Among them, the control parameters for clutch position requirements are used to control the movement of the clutch to a target position during the engagement and disengagement processes in the starting stage. The control parameters for clutch speed requirements are used to control the movement of the clutch at a target speed during the engagement and disengagement processes in the starting stage. When the vehicle enters the starting stage, the vehicle controller executes the starting clutch control program to control the engagement and disengagement of the clutch according to the pre-set control parameters for clutch position requirements and control parameters for clutch speed requirements, so as to provide a good starting experience for the user.

[0003] However, the pre-set starting clutch control program is only applicable to specific vehicle models and clutch models. When the vehicle uses a different model of clutch, or when the starting clutch control program of a certain vehicle model is applied to another vehicle model, due to the mismatch of the control parameters for clutch position requirements and control parameters for clutch speed requirements, problems such as slow clutch engagement during the starting stage and the inability of the clutch to engage with the transmission will occur, and thus a good starting experience cannot be brought to the user.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] In this application, the terms "include", "comprise" or any other variation thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0041] Refer to Figure 1 , an embodiment of this application proposes a clutch control method, which can be applied to devices or modules with control functions such as a vehicle controller and an electronic control unit. The clutch control method specifically includes the following steps:

[0042] S101. Detect the maximum acceleration of the vehicle in the current starting stage.

[0043] Specifically, the starting stage of the vehicle refers to the transition process from stationary to moving. When the vehicle enters the starting stage, detect the maximum acceleration of the vehicle in the starting stage, so as to judge whether the current starting process can meet the comfort requirements of the user according to the maximum acceleration of the vehicle in the starting stage. Specifically, in the starting stage, if the maximum acceleration of the vehicle is too large, it is easy to cause the user to have a sense of driving impact and poor user experience. If the maximum acceleration of the vehicle is too small, the starting speed of the vehicle will be too slow, and it is difficult to quickly reach the vehicle speed required by the user, which will also bring poor comfort to the user and cause a bad starting experience. Therefore, it is necessary to execute step S101 to determine whether a good starting experience can be brought to the user currently.

[0044] Optionally, before executing step S101, it further includes receiving a starting signal, and then starting to execute step S101 under the trigger of the starting signal. The starting signal can be understood as a signal generated when the vehicle enters the starting stage, which is used to indicate that the vehicle enters the starting stage. Exemplarily, after receiving the starting signal, trigger the execution of the starting clutch control program, and then execute the step of detecting the maximum acceleration of the vehicle in the current starting stage in the starting clutch control program.

[0045] Optionally, during the starting phase of the vehicle, in addition to performing step S101, starting control of the vehicle can also be performed. Specifically, the engagement process of the clutch can be controlled according to the first control parameter and the second control parameter in the current starting phase, so that the vehicle completes starting. Among them, the first control parameter (which can also be called the clutch position demand control parameter) is used to control the clutch to move to the target position during the engagement process in the starting phase, and the second control parameter (which can also be called the clutch speed demand control parameter) is used to control the clutch to move at the target speed during the engagement process in the starting phase.

[0046] Optionally, the first control parameter is also used to control the clutch to move to the target position during the disengagement process in the starting phase. The second control parameter is also used to control the clutch to move at the target speed during the disengagement process in the starting phase. That is, during the starting phase of the vehicle, the engagement and disengagement of the clutch can be controlled according to the first control parameter and the second control parameter.

[0047] It should be noted that the target position to which the first control parameter moves during the clutch engagement process is different from the target position to which the first control parameter moves during the clutch disengagement process. The target position during the engagement process is a position for engaging the clutch with the transmission. The target position during the disengagement process is a position for disengaging the clutch from the transmission. The first control parameter in the embodiments of the present application can be understood as a parameter that at least includes the target position. The target position can be understood as a specific position to which a device or module with control functions needs to control the clutch to move. The specific target position can be set according to experience. For example, the target position during the clutch engagement process can be set to 16 on the x-axis, and the target position during the clutch disengagement process is 20 on the x-axis. The coordinate representation method of the target position and the establishment method of the coordinate system are not limited in the embodiments of the present application.

[0048] It should also be noted that the second control parameter in the embodiments of the present application can be understood as a parameter that at least includes the target speed. The target speed mentioned in the embodiments of the present application can also be a specific speed that a device or module with control functions needs to control the clutch to reach when moving. It should be noted that the target speed in the second control parameter can be a combination of one or more specific speeds. For example, the target speed can be speed a from 0 to 1 ms, and speed b from 1 ms to 5 ms.

[0049] Optionally, in the current starting stage, there are many ways to control the clutch according to the first control parameter and the second control parameter in the current starting stage. For example, according to a specific clutch position movement rule, during the process of clutch engagement and disengagement, the clutch is controlled to move to the target position. According to a specific clutch speed change rule, during the process of clutch engagement and disengagement, the clutch is controlled to move at the target speed. For example, the first control parameter is used to control the target position that the clutch needs to move to during the engagement process to be 16 on the x-axis. Then, according to the clutch position movement rule, the clutch can be first controlled to move to 18 on the x-axis, then the clutch is controlled to move to 17 on the x-axis, and finally the clutch is controlled to move to 16 on the x-axis to complete the clutch engagement. That is, there are many ways to control the clutch to complete the engagement specifically according to the first control parameter and the second control parameter, and the embodiments of the present application do not limit it.

[0050] Optionally, there are many ways to execute step S101. For example, the maximum acceleration of the vehicle in the starting stage can be calculated based on data such as the engine speed and torque in the starting stage, or the acceleration of the vehicle can be detected in real time in the current starting stage, and then the maximum acceleration in the starting stage can be determined. The embodiments of the present application do not limit the method for detecting the maximum acceleration of the vehicle in the starting stage.

[0051] S102. Determine whether the maximum acceleration of the vehicle is within the target acceleration range, where the target acceleration range is: greater than or equal to the first acceleration threshold and less than or equal to the second acceleration threshold. The first acceleration threshold is the minimum acceleration that satisfies the user's comfort requirement in the starting stage, and the second acceleration threshold is the maximum acceleration that satisfies the user's comfort requirement in the starting stage.

[0052] Among them, the target acceleration range can be understood as the acceleration range that can meet the user's comfort requirement in the starting stage of the vehicle. When the maximum acceleration of the vehicle is within the target acceleration range, it means that the first control parameter and the second control parameter used in the current starting stage are adapted to the current vehicle, and there is no need to readjust the first control parameter and the second control parameter, that is, the process ends. If the maximum acceleration of the vehicle is not within the target acceleration range, it means that the first control parameter and / or the second control parameter used in the current starting stage are not adapted to the current vehicle. For example, it may not be adapted to the current vehicle model or the current clutch model, which may lead to problems such as slow clutch engagement and incomplete clutch engagement with the transmission, and ultimately the maximum acceleration of the vehicle cannot bring a good starting experience to the user. Therefore, when it is determined that the maximum acceleration of the vehicle is not within the target acceleration range, step S103 needs to be executed so that the maximum acceleration of the vehicle can be within the target acceleration range in the next starting stage.

[0053] Optionally, the first acceleration threshold and the second acceleration threshold can be preset according to multiple tests or other methods, that is, the target acceleration range can be a preset fixed acceleration range. Optionally, the first acceleration threshold and the second acceleration threshold can also be calculated based on current vehicle condition parameters such as the current throttle opening, engine speed, and torque, that is, in real time, according to some parameters reflecting the vehicle operation state during the current starting stage, to calculate the first acceleration threshold and the second acceleration threshold, and then determine the target acceleration range. Since the target acceleration range determined in this way is based on the parameters of the current vehicle driving state, the determined target acceleration range can conform to the current driving habits of the user and can more accurately reflect the acceleration range that meets the user's comfort requirements.

[0054] S103. Adjust the first control parameter of the current starting stage to obtain the first control parameter of the next starting stage, and / or adjust the second control parameter of the current starting stage to obtain the second control parameter of the next starting stage, where the first control parameter is used to control the clutch to move to the target position during the engagement process in the starting stage, and the second control parameter is used to control the clutch to move at the target speed during the engagement process in the starting stage.

[0055] Among them, the first control parameter and the second control parameter can refer to the foregoing descriptions of the first control parameter and the second control parameter, which will not be elaborated here. Since the maximum acceleration of the vehicle in the current starting stage is not within the target acceleration range, it is necessary to adjust the first control parameter, and / or the second control parameter of the current starting stage.

[0056] That is, in step S103, only the first control parameter of the current stage can be adjusted to obtain the adjusted first control parameter as the first control parameter of the next starting stage. Among them, the first control parameter of the next starting stage refers to the parameter used to control the position of the clutch when entering the next starting stage. The second control parameter of the current starting stage can remain unadjusted and continue to be used to control the speed of the clutch in the next starting stage. Since the first control parameter has been adjusted, the position control of the clutch in the next starting stage has been adjusted, which can better adapt to the current vehicle, so that the maximum acceleration of the vehicle detected in the next starting stage is within, or closer to, the target acceleration range.

[0057] Similarly, it is also possible to only adjust the second control parameter in the current stage to obtain the adjusted second control parameter as the second control parameter for the next starting stage. Herein, the second control parameter for the next starting stage refers to the parameter used to control the moving speed of the clutch when entering the next starting stage. The first control parameter for the current starting stage can remain unadjusted and continue to be used to control the position of the clutch in the next starting stage. Since the second control parameter has been adjusted, the speed control of the clutch in the next starting stage is adjusted, enabling better adaptation to the current vehicle, such that the maximum acceleration of the vehicle detected in the next starting stage falls within, or is closer to, the target acceleration range.

[0058] In step S103, it is also possible to adjust both the first control parameter and the second control parameter in the current stage to obtain the adjusted first control parameter and second control parameter as the first control parameter and second control parameter for the next starting stage. Since the first control parameter and the second control parameter have been adjusted, the speed and position control of the clutch in the next starting stage are adjusted, enabling better adaptation to the current vehicle, such that the maximum acceleration of the vehicle detected in the next starting stage falls within, or is closer to, the target acceleration range.

[0059] After step S103 is executed, when the vehicle enters the next starting stage, the clutch is controlled according to the first control parameter and the second control parameter for the next starting stage obtained in step S103. Since the first control parameter and the second control parameter for the next starting stage are adjusted compared with the first control parameter and the second control parameter for the current starting stage, the first control parameter and the second control parameter for the next starting stage obtained after adjustment can be adapted to the vehicle. When using the first control parameter and the second control parameter for the next starting stage to control the clutch in the next starting stage, the maximum acceleration of the vehicle can be within the target acceleration range, meeting the comfort requirements of the user in the starting stage.

[0060] Optionally, to ensure that the maximum acceleration of the vehicle can meet the comfort requirements of the user in the starting stage, the process shown in Figure 1 can be triggered every time the vehicle enters the starting stage. Thus, in the case where the maximum acceleration of the vehicle is not within the target acceleration range, the first control parameter, and / or the second control parameter can be continuously adjusted until the maximum acceleration of the vehicle is within the target acceleration range.

[0061] Optionally, referring to Figure 2 , in a specific embodiment of the present application, adjusting the first control parameter for the current starting stage to obtain the first control parameter for the next starting stage includes:

[0062] S201. If the maximum acceleration of the vehicle is less than the first acceleration threshold, then adjust the target position in the first control parameter of the current starting stage from the first engagement position to the second engagement position to obtain the first control parameter for the next starting stage, where during the engagement process of the clutch in the starting stage, the distance moved to the second engagement position is greater than the distance moved to the first engagement position.

[0063] Specifically, when it is determined in step S102 that the maximum acceleration of the vehicle is not within the target acceleration range, there are generally two possible cases: one is the case where the acceleration of the vehicle is less than the first acceleration threshold, and the other is the case where the acceleration of the vehicle is greater than the second acceleration threshold. These two cases can adjust the first control parameter in different ways. When the maximum acceleration of the vehicle is less than the first acceleration threshold, the first control parameter is adjusted in the manner of step S201. When the maximum acceleration of the vehicle is greater than the second acceleration threshold, the first control parameter is adjusted in the manner of step S202.

[0064] It should also be noted that the judgment in step S102 can actually be divided into three judgment results, namely: (1) it is judged that the maximum acceleration of the vehicle is less than the first acceleration threshold; (2) it is judged that the maximum acceleration of the vehicle is greater than the second acceleration threshold; (3) it is judged that the maximum acceleration of the vehicle is not within the target acceleration range. And there are many ways to obtain one of these results: for example, it can first be judged whether the maximum acceleration of the vehicle is within the target acceleration range. If it is not within the target acceleration range, then it is judged whether the maximum acceleration of the vehicle is less than the first acceleration threshold. If it is judged that the maximum acceleration of the vehicle is less than the first acceleration threshold, then step S201 is executed. If it is judged that the maximum acceleration of the vehicle is not less than the first acceleration threshold, then step S202 is executed.

[0065] For another example, it can also be to first judge whether the maximum acceleration of the vehicle is less than the first acceleration threshold. If so, then step S201 is executed. If not, then it is judged whether the maximum acceleration of the vehicle is greater than the second acceleration threshold. If so, then step S202 is executed. If not, then it is judged that the maximum acceleration of the vehicle is within the target acceleration range, and the process ends.

[0066] For another example, it can also be to first judge whether the maximum acceleration of the vehicle is greater than the second acceleration threshold. If so, step S202 is executed. If not, then it is judged whether the maximum acceleration of the vehicle is less than the first acceleration threshold. If so, step S201 is executed. If not, then it is judged that the maximum acceleration of the vehicle is within the target acceleration range, and the process ends.

[0067] It should be noted that the embodiments of the present application do not limit the sequence of determining whether the maximum acceleration of the vehicle is less than the first acceleration threshold, determining whether the maximum acceleration of the vehicle is greater than the second acceleration threshold, and determining whether the maximum acceleration of the vehicle is within the target acceleration range.

[0068] Specifically, in step S201, the maximum acceleration of the vehicle is less than the first acceleration threshold, that is, the maximum acceleration of the vehicle is too small to meet the comfort requirements of the user. To meet the comfort requirements of the user, it is necessary to increase the maximum acceleration of the vehicle. Specifically, the target position in the first control parameter at the current starting stage can be adjusted from the first engagement position to the second engagement position to obtain the first control parameter for the next starting stage. During the engagement process of the clutch at the starting stage, the distance moved to the second engagement position is greater than the distance moved to the first engagement position. That is, the second engagement position is closer to the position where the transmission is located compared to the first engagement position. Thus, it can be fully engaged with the transmission during the engagement process, avoiding the situation where the maximum acceleration of the vehicle is too small due to incomplete engagement between the clutch and the transmission, and increasing the maximum acceleration of the vehicle at the starting stage.

[0069] The first engagement position refers to the target position in the first control parameter at the current starting stage, while the second engagement position is the target position in the first control parameter for the next starting stage. The position change amount between the second engagement position and the first engagement position can be set arbitrarily. For example, a fixed position change amount can be adjusted, such as the position change amount each time is 2 millimeters.

[0070] For another example, the position change amount between the second engagement position and the first engagement position can be determined according to the difference between the maximum acceleration of the vehicle and the first acceleration threshold. Specifically, the greater the difference between the maximum acceleration of the vehicle and the first acceleration threshold, the greater the position change amount between the second engagement position and the first engagement position, and the greater the adjustment range of the first control parameter at the current starting stage.

[0071] Exemplarily, the position change amount between the second engagement position and the first engagement position can be determined based on the difference between the maximum acceleration of the vehicle and the first acceleration threshold, as well as the position change amount coefficient. Among them, the position change amount coefficient can be set according to multiple tests or experience, and the specific setting method is not limited in the embodiments of the present application. Specifically, the difference between the maximum acceleration a of the vehicle and the first acceleration threshold a1, as well as the position change amount coefficient KL are substituted into the first formula, and the position change amount ΔL1 between the second engagement position and the first engagement position is calculated by the first formula. Among them, the first formula is: ΔL1 = kL * (a - a1). For example, during the engagement process of the clutch, the initial position of the clutch is at 20 mm on the pre-established coordinate axis, the first engagement position is at 16 mm on the coordinate axis, the first acceleration threshold a1 is 2.78 m / s, the maximum acceleration a at the current starting stage is 1.78 m / s, and KL is set to 2. Then, ΔL1 is calculated to be -2, that is, the second engagement position is 16 - 2 = 14 mm. That is, the target position of the first control parameter at the next starting stage is at 14 mm. When entering the next starting stage, the clutch will be controlled to move from the initial position of 20 mm to the target position of 14 mm.

[0072] S202. If the maximum acceleration of the vehicle is greater than the second acceleration threshold, adjust the target position in the first control parameter of the current starting stage from the first engagement position to the third engagement position to obtain the first control parameter for the next starting stage, where the distance that the clutch moves to the third engagement position during the engagement process in the starting stage is less than the distance that it moves to the first engagement position.

[0073] Regarding the process and method of determining that the maximum acceleration of the vehicle is greater than the second acceleration threshold, reference can be made to the relevant content in the foregoing "Determining Whether the Maximum Acceleration of the Vehicle is Less than the First Acceleration Threshold, Determining Whether the Maximum Acceleration of the Vehicle is Greater than the Second Acceleration Threshold, and Determining Whether the Maximum Acceleration of the Vehicle is within the Target Acceleration Range" section, which will not be elaborated here.

[0074] Specifically, in step S202, the maximum acceleration of the vehicle is greater than the second acceleration threshold, that is, the maximum acceleration of the vehicle is too large to meet the comfort requirements of the user. To meet the comfort requirements of the user, it is necessary to reduce the maximum acceleration of the vehicle. Specifically, the target position in the first control parameter in the current starting stage can be adjusted from the first engagement position to the third engagement position to obtain the first control parameter in the next starting stage. During the engagement process of the clutch in the starting stage, the distance that the clutch moves to the third engagement position is less than the distance that it moves to the first engagement position. That is, the third engagement position is farther from the position where the transmission is located than the first engagement position. Therefore, the clutch can be adjusted to a more appropriate engagement position in the next starting stage, avoiding excessive maximum acceleration of the vehicle caused by excessive engagement between the clutch and the transmission, and reducing the maximum acceleration of the vehicle in the starting stage.

[0075] The first engagement position refers to the target position in the first control parameter in the current starting stage, while the third engagement position is the target position in the first control parameter in the next starting stage. The position change amount between the third engagement position and the first engagement position can be set arbitrarily. For example, a fixed position change amount can be adjusted, such as the position change amount each time is 2 millimeters.

[0076] For another example, the position change amount between the third engagement position and the first engagement position can be determined according to the difference between the maximum acceleration of the vehicle and the second acceleration threshold. Specifically, the greater the difference between the maximum acceleration of the vehicle and the second acceleration threshold, the greater the position change amount between the third engagement position and the first engagement position, and the greater the adjustment range of the first control parameter in the current starting stage.

[0077] Exemplarily, the position change amount between the third engagement position and the first engagement position can be determined based on the difference between the maximum acceleration of the vehicle and the second acceleration threshold, and the position change amount coefficient. The position change amount coefficient can be set according to multiple tests or experience, and the specific setting method is not limited in the embodiments of the present application. Specifically, the difference between the maximum acceleration a of the vehicle and the second acceleration threshold a2, and the position change amount coefficient kL are substituted into the second formula, and the position change amount ΔL2 between the third engagement position and the first engagement position is calculated by the second formula. The second formula is: ΔL2 = kL * (a - a2). For example, during the engagement process of the clutch, the initial position of the clutch is at 20 mm on the pre-established coordinate axis, the first engagement position is at 16 mm on the coordinate axis, the second acceleration threshold a2 is 2.78 m / s, the maximum acceleration a at the current starting stage is 3.78 m / s, and KL is set to 2. Then, ΔL2 is calculated to be 2, that is, the third engagement position is 16 + 2 = 18 mm. That is, the target position of the first control parameter at the next starting stage is at 18 mm. When entering the next starting stage, the clutch will be controlled to move from the initial position of 20 mm to the target position of 18 mm.

[0078] It should be noted that the position change amount coefficient KL in the first formula and the second formula in the embodiments of the present application takes a positive number.

[0079] Optionally, in a specific embodiment of the present application, when it is determined in step S102 that the maximum acceleration of the vehicle is not within the target acceleration range, an implementation manner of "adjusting the second control parameter for the current starting stage to obtain the second control parameter for the next starting stage" in step S103 can be as Figure 3 shown:

[0080] S301. If the maximum acceleration of the vehicle is less than the first acceleration threshold, increase the target speed in the second control parameter for the current starting stage by a first change amount to obtain the second control parameter for the next starting stage.

[0081] The specific process and method for determining that the maximum acceleration of the vehicle is less than the first acceleration threshold can refer to the relevant part of the foregoing step S201, and will not be elaborated here.

[0082] Specifically, in step S301, the maximum acceleration of the vehicle is less than the first acceleration threshold, that is, the maximum acceleration of the vehicle is too small to meet the comfort requirements of the user. To meet the comfort requirements of the user, it is necessary to increase the maximum acceleration of the vehicle. Specifically, the target speed in the current starting stage can be increased by a first change amount, that is, the target speed in the second control parameter is increased, so as to obtain the second control parameter for the next starting stage. As a result, during a starting stage, the clutch can complete the engagement with the gearbox faster during the engagement process, and the maximum acceleration of the vehicle during the starting stage is increased.

[0083] Among them, the first change amount can be set arbitrarily. For example, the first change amount can be set to a fixed value, or the first change amount can be determined according to the difference between the first acceleration threshold and the maximum acceleration of the vehicle. Specifically, the greater the difference between the first acceleration threshold and the maximum acceleration of the vehicle, the greater the first change amount, and the greater the adjustment range of the second control parameter for the current starting stage.

[0084] Exemplarily, the first change amount can be determined according to the difference between the first acceleration threshold and the maximum acceleration of the vehicle, and the speed change amount coefficient. Among them, the speed change amount coefficient can be set according to multiple tests or experience, and the specific setting method is not limited in the embodiments of the present application. Specifically, the difference between the first acceleration threshold a1 and the maximum acceleration a of the vehicle, and the position change amount coefficient kv are substituted into the third formula to calculate the first change amount Δv1. Among them, the third formula is: Δv1 = kv * (a1 - a).

[0085] S302. If the maximum acceleration of the vehicle is greater than the second acceleration threshold, the target speed in the second control parameter for the current starting stage is reduced by a second change amount to obtain the second control parameter for the next starting stage.

[0086] Among them, for the specific process and method of determining that the maximum acceleration of the vehicle is greater than the second acceleration threshold, reference can be made to the relevant part of the foregoing step S202, which will not be elaborated here.

[0087] Specifically, in step S302, the maximum acceleration of the vehicle is greater than the second acceleration threshold, that is, the maximum acceleration of the vehicle is too large to meet the comfort requirements of the user. To meet the comfort requirements of the user, it is necessary to reduce the maximum acceleration of the vehicle. Specifically, the target speed in the current starting stage can be reduced by a second change amount, that is, the target speed in the current starting stage is reduced, so that the clutch will not engage with the gearbox prematurely during the engagement process, and the maximum acceleration of the vehicle during the starting stage is reduced.

[0088] Among them, the second change amount can be set arbitrarily. For example, the second change amount can be set to a fixed value, or the second change amount can be determined according to the difference between the second acceleration threshold and the maximum acceleration of the vehicle. Specifically, the greater the difference between the second acceleration threshold and the maximum acceleration of the vehicle, the greater the second change amount, and the greater the adjustment range of the second control parameter in the current starting stage.

[0089] Exemplarily, the second change amount can be determined according to the difference between the second acceleration threshold and the maximum acceleration of the vehicle, and the speed change amount coefficient. Among them, the speed change amount coefficient can be set according to multiple tests or experience, and the specific setting method is not limited in the embodiments of the present application. Specifically, the difference between the second acceleration threshold a2 and the maximum acceleration a of the vehicle, and the position change amount coefficient kv are substituted into the fourth formula to calculate the second change amount Δv2. Among them, the fourth formula is: Δv2 = kv * (a2 - a).

[0090] It should be noted that the speed change amount coefficient kv in the third formula and the fourth formula in the embodiments of the present application takes a positive number. Since a2 is less than a, the second change amount Δv2 calculated in the fourth formula is negative, indicating that the target speed needs to be reduced by the second change amount.

[0091] The clutch control method provided by the embodiments of the present application detects the maximum acceleration of the vehicle in the current starting stage, and then, when it is determined that the maximum acceleration is not within the target acceleration range, adjusts the first control parameter in the current starting stage to obtain the first control parameter in the next starting stage, and / or adjusts the second control parameter in the current starting stage to obtain the second control parameter in the next starting stage. Among them, the first control parameter is used to control the clutch to move to the target position during the engagement process in the starting stage, and the second control parameter is used to control the clutch to move at the target speed during the engagement process in the starting stage. The target acceleration range is: greater than or equal to the first acceleration threshold and less than or equal to the second acceleration threshold. The first acceleration threshold is the minimum acceleration that satisfies the user's comfort requirement in the starting stage, and the second acceleration threshold is the maximum acceleration that satisfies the user's comfort requirement in the starting stage. The first control parameter and the second control parameter in the next starting stage obtained after adjustment can be adapted to the vehicle. When using the first control parameter and the second control parameter in the next starting stage to control the clutch in the next starting stage, the maximum acceleration of the vehicle can be within the target acceleration range, meeting the user's comfort requirement in the starting stage.

[0092] This application takes into account the different requirements for the target position and target speed of the clutch during the vehicle starting stage for different vehicle models or different clutch models. By the magnitude of the maximum acceleration of the vehicle during the starting stage, the first control parameter and the second control parameter are adjusted in real time, and finally the target acceleration range that can meet the user's comfort requirements is achieved.

[0093] Referring to Figure 4 , an embodiment of this application discloses another clutch control method, which specifically includes the following steps:

[0094] S401. Detect the maximum acceleration of the vehicle during the current starting stage.

[0095] Among them, the execution process and principle of step S401 can refer to the aforementioned Figure 1 shown step S101, which will not be elaborated here.

[0096] S402. Calculate a first acceleration threshold according to the throttle opening during the current starting stage, a preset first throttle opening correction coefficient, and a preset first acceleration value.

[0097] Among them, the preset first acceleration value can be determined based on multiple tests. For example, the minimum acceleration value of multiple vehicles of the same model as the vehicle in the embodiment of this application during the starting stage can be tested, and then used as the preset first acceleration value. The preset first throttle opening correction coefficient can also be set based on multiple tests. For example, the minimum value of the throttle opening correction coefficient tested for this vehicle in multiple tests can be selected as the preset first throttle opening correction coefficient. The embodiment of this application does not limit the setting method of the preset first throttle opening correction coefficient and the preset first acceleration value.

[0098] Exemplarily, the way to execute step S402 is: substitute the throttle opening r during the current starting stage, the preset first throttle opening correction coefficient ka1, and the preset first acceleration value a10 into the fifth formula to calculate the first acceleration threshold a1. Among them, the fifth formula is: a1 = a10 + ka1 * r.

[0099] S403. Calculate a second acceleration threshold according to the throttle opening during the current starting stage, a preset second throttle opening correction coefficient, and a preset second acceleration value, where the preset first acceleration value is less than the preset second acceleration value.

[0100] Among them, the preset second acceleration value can be determined based on multiple tests. For example, the maximum acceleration values of multiple vehicles of the same model as the vehicle in the embodiment of the present application during the starting stage can be tested, and then used as the preset second acceleration value. The preset second throttle opening correction coefficient can also be set based on multiple tests. For example, the maximum value of the throttle opening correction coefficient tested for the vehicle in multiple tests can be selected as the preset second throttle opening correction coefficient. The embodiment of the present application does not limit the setting method of the preset second throttle opening correction coefficient and the preset second acceleration value.

[0101] Exemplarily, the manner of executing step S403 is: substituting the throttle opening r in the current starting stage, the preset second throttle opening correction coefficient ka2, and the preset second acceleration value a20 into the sixth formula to calculate the second acceleration threshold a2. Among them, the sixth formula is: a2 = a20 + ka2 * r.

[0102] It should be noted that the embodiment of the present application does not limit the execution sequence of steps S401 to S403.

[0103] In step S402, based on the current throttle opening situation, the preset first throttle opening correction coefficient, and the preset first acceleration value, the minimum acceleration (i.e., the first acceleration threshold) that meets the user's comfort requirement under the user's driving habit is determined. And in step S403, based on the current throttle opening situation, the preset second throttle opening correction coefficient, and the preset second acceleration value, the maximum acceleration (i.e., the second acceleration threshold) that meets the user's comfort requirement under the user's driving habit is determined. Then, through the first acceleration threshold and the second acceleration threshold, a target acceleration range (greater than or equal to the first acceleration threshold and less than or equal to the second acceleration threshold) that conforms to the current user's driving habit is determined. The target acceleration range determined in this way better meets the user's comfort requirement.

[0104] S404. Determine whether the maximum acceleration of the vehicle is within the target acceleration range, where the target acceleration range is: greater than or equal to the first acceleration threshold and less than or equal to the second acceleration threshold, the first acceleration threshold is the minimum acceleration that meets the user's comfort requirement in the starting stage, and the second acceleration threshold is the maximum acceleration that meets the user's comfort requirement in the starting stage.

[0105] If it is determined that the maximum acceleration of the vehicle is within the target acceleration range, the process ends. If the maximum acceleration of the vehicle is not within the target acceleration range, step S405 is executed.

[0106] Among them, the execution process and principle of step S404 can refer to Figure 1 step S102 of, which will not be elaborated here.

[0107] S405. Adjust the first control parameter of the current starting stage to obtain the first control parameter of the next starting stage, and / or adjust the second control parameter of the current starting stage to obtain the second control parameter of the next starting stage, where the first control parameter is used to control the clutch to move to a target position during the engagement process in the starting stage, and the second control parameter is used to control the clutch to move at a target speed during the engagement process in the starting stage.

[0108] Among them, the execution process and principle of step S405 can refer to Figure 1 step S103 of , which will not be elaborated here.
