Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a vehicle clutch wear detection method, device, electronic equipment and storage medium. Background Art

[0002] In conventional energy vehicles with automatic transmissions, dry clutches are widely used due to their simple structure and easy maintenance. Dry clutches mainly transmit and interrupt torque through the contact and separation of friction plates. In vehicle starting, creeping, and slow reversing, the clutch needs to slide between the master and slave parts to ensure smooth power transmission. This sliding process will cause wear of the friction plates, thereby affecting the performance of the clutch. As wear increases, the torque transmission capacity of the clutch will gradually decrease, which may eventually cause the vehicle to be unable to drive normally. However, in the prior art, the wear detection of the clutch has the following disadvantages:

[0003] 1. Indirect visibility: The wear of the clutch friction plate is not easy to observe directly and needs to be inspected by disassembling the clutch, which increases the complexity and cost of detection;

[0004] 2. Inaccurate estimation of the degree of wear: Usually the degree of clutch wear is judged based on the vehicle's mileage. This method considers a relatively single factor and is difficult to fully reflect the degree of clutch wear;

[0005] 3. Lack of real-time monitoring: Existing detection methods often cannot provide real-time wear data, resulting in the inability to understand the current status of the clutch in a timely manner, which may lead to missing the best time for replacement.

[0006] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0041] Figure 1 is a flow chart of a vehicle clutch wear detection method according to one embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0042] Step S10, obtaining static semi-clutch starting point information and dynamic semi-clutch starting point information of the target vehicle, wherein the static semi-clutch starting point information is used to indicate the semi-clutch starting point information of the clutch of the target vehicle in a static self-learning state, and the dynamic semi-clutch starting point information is used to determine the semi-clutch starting point information of the clutch in a dynamic self-learning state;

[0043] In step S10, the above clutch is used to characterize a dry clutch of the target vehicle. A dry clutch is a clutch used in a vehicle transmission system, and its main function is to transfer torque between the engine and the transmission while allowing the engine to be separated from the transmission system when needed. This clutch does not require liquid (such as oil) to transmit pressure.

[0044] The above-mentioned static semi-clutch starting point information is used to characterize the static semi-clutch starting point information obtained when the target vehicle is offline and the clutch static self-learning state is activated after power-on. The present invention is explained by taking the clutch position sensor as a positive value, and the sensor value changes from small to large when the clutch moves from the disengagement point to the engagement point position.

[0045] The above-mentioned dynamic semi-clutch starting point is used to represent that when the target vehicle meets the dynamic self-learning conditions, the dynamic self-learning of the clutch is activated, and the dynamic semi-clutch starting point information is obtained when the clutch is in the dynamic self-learning state.

[0046] Specifically, when the clutch of the target vehicle is in a static self-learning state, the static semi-clutch starting point of the clutch is obtained, which is recorded as KPD0, wherein KPD0 can be stored when powered off and read when powered on. When the clutch is in a dynamic self-learning state, the dynamic semi-clutch starting point information is obtained, wherein the dynamic semi-clutch starting point can also be stored when powered off and read when powered on. The semi-clutch starting point in the present invention is the point at which the clutch starts to transmit torque, that is, the point at which the clutch gradually engages during the self-learning process and the transmission input shaft starts to rotate.

[0047] Step S12, determining initial semi-linked starting point information based on the static semi-linked starting point information and the dynamic semi-linked starting point information;

[0048] Specifically, in order to eliminate the influence of clutch position sensor signal fluctuation and error in static / dynamic self-learning state on clutch semi-clutch starting point, initial semi-clutch starting point information is determined based on static semi-clutch starting point information and dynamic semi-clutch starting point information.

[0049] Specifically, a plurality of dynamic semi-linked starting point information is obtained, and the static semi-linked starting point information and the dynamic semi-linked starting point information are averaged to determine an initial semi-linked starting point value, which is recorded as IntKP.

[0050] Step S14, fitting the dynamic semi-linked starting point information to determine the current semi-linked starting point information;

[0051] Specifically, the dynamic semi-linked starting point information is fitted using a preset fitting algorithm to obtain a linear regression equation of the semi-linked starting point, and the current semi-linked starting point information is determined according to the linear regression equation.

[0052] Step S16, determining the wear information of the clutch based on the initial semi-clutch starting point information and the current semi-clutch starting point information, wherein the wear information is used to determine the wear level of the clutch.

[0053] In step S16, the wear level of the clutch can be divided into abnormal wear of the clutch, and the driver needs to repair and maintain it in time, and the clutch fails, and the driver needs to replace the clutch.

[0054] Specifically, the wear information of the clutch is determined based on the initial semi-clutch starting point information and the current semi-clutch starting point information. When the wear level of the clutch is abnormal wear, the driver is reminded to perform timely maintenance; when the wear level of the clutch is clutch failure, the driver is reminded to replace the clutch.

[0055] Based on the above steps S10 to S16, the static semi-clutch starting point information and the dynamic semi-clutch starting point information of the target vehicle are obtained, the initial semi-clutch starting point information is determined based on the static semi-clutch starting point information and the dynamic semi-clutch starting point information, and the dynamic semi-clutch starting point information is fitted to determine the current semi-clutch starting point information, and finally the wear information of the clutch is determined based on the initial semi-clutch starting point information and the current semi-clutch starting point information, thereby achieving the purpose of accurately and real-time detection of the degree of wear of the clutch, thereby achieving the technical effect of improving the efficiency of vehicle dry clutch wear detection and the accuracy of wear degree judgment, and further solving the technical problems of low efficiency of vehicle dry clutch wear detection and low accuracy of wear degree judgment in related technologies.

[0056] Optionally, in step S10, obtaining the dynamic semi-coordinated starting point information of the target vehicle includes:

[0057] Step S101, obtaining a lubricating oil temperature value in a transmission of a target vehicle during driving;

[0058] In step S101, if there is no oil temperature sensor and the temperature value of the lubricating oil in the transmission of the target vehicle cannot be collected during driving, the water temperature value in the cooling system of the engine may also be referred to.

[0059] Step S102, in response to the lubricating oil temperature value being greater than a preset temperature value, determining the semi-cooperative starting point information corresponding to the lubricating oil temperature value as the candidate dynamic semi-cooperative starting point information;

[0060] Specifically, when the lubricating oil temperature in the transmission is low, the transmission input shaft resistance is large, and the dynamic semi-clutch starting point value in the clutch dynamic self-learning state is too large, so the semi-clutch starting point value when the transmission oil temperature is greater than the preset temperature value is selected as the alternative dynamic semi-clutch starting point value. Above the preset temperature value, the lubricating oil temperature has a low impact on the clutch dynamic self-learning semi-clutch starting point value. For example, if the preset temperature value is 10 degrees Celsius, the semi-clutch starting point value when the lubricating oil temperature is greater than 10 degrees Celsius is used as the alternative dynamic semi-clutch starting point value.

[0061] Step S103, screening the candidate dynamic semi-coordinated starting point information based on the semi-coordinated starting point quantity constraint condition to obtain dynamic semi-coordinated starting point information, wherein the semi-coordinated starting point quantity constraint condition is determined based on the number of candidate dynamic semi-coordinated starting points and a first preset number of dynamic semi-coordinated starting points.

[0062] In step S103, the above-mentioned semi-linked starting point quantity constraint condition is as shown in expression (1).

[0063] num=min(M,Y) (1)

[0064] Wherein, M represents the number of dynamic semi-linked starting points that need to be obtained, that is, the first preset number of dynamic semi-linked starting points; Y represents the number of candidate dynamic semi-linked starting points, where Y≥0.

[0065] Specifically, first, the lubricating oil temperature value of the target vehicle during driving is obtained; then, when the lubricating oil temperature value is greater than the preset temperature value, the semi-linked starting point information corresponding to the lubricating oil temperature value is determined as the candidate dynamic semi-linked starting point information; finally, the candidate dynamic semi-linked starting point information is screened based on the semi-linked starting point quantity constraint condition to obtain the dynamic semi-linked starting point information. For example, the preset temperature value is 10°C, M=100, if the semi-linked starting point quantity Y=50 corresponding to the lubricating oil temperature value greater than 10°C is satisfied, 50 semi-linked starting points KPD1, ..., KPD50 greater than 10°C are recorded and stored, if the semi-linked starting point quantity Y=100 corresponding to the lubricating oil temperature value greater than 10°C is satisfied, 100 semi-linked starting points KPD1, ..., KPD100 greater than 10°C are recorded and stored, if the semi-linked starting point quantity Y=200 corresponding to the lubricating oil temperature value greater than 10°C is satisfied, 100 semi-linked starting points KPD101, ..., KPD200 greater than 10°C are recorded and stored. The minimum (M, Y) dynamic semi-linkage starting points that meet the requirements can be stored when the power is turned off and read when the power is turned on. If there is no oil temperature sensor, the above operation can also be performed by referring to the engine water temperature.

[0066] Based on the above steps S101 to S103, the lubricating oil temperature value of the target vehicle during driving is obtained; in response to the lubricating oil temperature value being greater than the preset temperature value, the semi-clutch starting point information corresponding to the lubricating oil temperature value is determined as the alternative dynamic semi-clutch starting point information; based on the constraint condition of the number of semi-clutch starting points, the alternative dynamic semi-clutch starting point information is screened to obtain the dynamic semi-clutch starting point information. By dynamically obtaining the semi-clutch starting point information, unnecessary data collection can be reduced and the efficiency of data processing can be improved. In addition, by screening data according to actual temperature conditions, the wear state of the clutch under different working conditions can be more accurately reflected, thereby improving the accuracy of judging the degree of wear of the vehicle's dry clutch.

[0067] Optionally, in step S12, determining the initial semi-coordinated starting point information based on the static semi-coordinated starting point information and the dynamic semi-coordinated starting point information includes:

[0068] Step S121, performing an average operation on the static semi-coordinated starting point information and a second preset number of candidate dynamic semi-coordinated starting point information to obtain initial semi-coordinated starting point information.

[0069] Step S121, performing an average operation on the static semi-coordinated starting point information and a second preset number of candidate dynamic semi-coordinated starting point information to obtain initial semi-coordinated starting point information.

[0070] Specifically, the second preset number of candidate dynamic semi-linked starting point information is recorded as KPD1, ..., KPD x For example, x=10, which means obtaining 10 candidate dynamic semi-linked starting point information. The obtained static semi-linked starting point value and the second preset number of candidate dynamic semi-linked starting point information are averaged to obtain the initial semi-linked starting point value, which is recorded as IntKP. The specific calculation process is shown in Expression (2).

[0071] IntKP=(KPD0+KPD1+KPD2+……KPD X ) / (X+1) (2)

[0072] Among them, IntKP represents the initial semi-clutch starting point value corresponding to the sub-historical driving distance; KPD0 represents the static semi-clutch starting point; KPD1, KPD2, ..., KPD X They respectively represent a second preset number of alternative dynamic semi-linked starting point values.

[0073] Based on the above steps S121 to S123, the static semi-clutch starting point information and the second preset number of alternative dynamic semi-clutch starting point information are averaged to obtain the initial semi-clutch starting point information. By combining static and dynamic data, the wear state of the clutch in different driving stages can be more accurately reflected, allowing real-time or near real-time monitoring of the wear state of the clutch, which helps to detect problems in time and make repairs.

[0074] Optionally, in step S14, the dynamic semi-linked starting point information is fitted to determine the current semi-linked starting point information including:

[0075] Step S141, fitting each group of sub-dynamic semi-linkage starting point information using a preset fitting algorithm to obtain a fitting equation;

[0076] Step S142, determining the current semi-linked starting point information corresponding to each of the sub-historical driving distances based on an independent variable and the fitting equation, wherein the independent variable is determined based on the constraint condition on the number of semi-linked starting points.

[0077] Specifically, the least square method is used to fit the linear regression equation corresponding to the dynamic semi-linkage starting point information. The specific calculation process of the linear regression equation is shown in expression (3).

[0078] DynKP=K*m+DynKP0,0≤m≤x (3)

[0079] Among them, m represents the independent variable, where 0≤m≤min(M,Y); x represents the number of dynamic semi-linkage starting point values; K represents the slope of the linear regression equation; DynKP0 represents the constant term of the linear regression equation.

[0080] Specifically, the current semi-linkage starting point value of the clutch is calculated, that is, m=min(M,Y) is substituted into the linear regression equation to obtain the current semi-linkage starting point value DynKP1=K*x+DynKP0. This can eliminate the influence of the clutch position sensor signal fluctuation and the dynamic self-learning error on the current semi-linkage starting point information of the clutch.

[0081] Based on the above steps S141 to S142, each group of the sub-dynamic semi-clutch starting point information is fitted using a preset fitting algorithm to obtain a fitting equation; the current semi-clutch starting point information corresponding to each sub-historical driving distance is determined based on the independent variable and the fitting equation, wherein the independent variable is determined based on the constraint condition of the number of semi-clutch starting points, which can more effectively utilize existing data, improve the efficiency and accuracy of data processing, and improve the reliability of clutch wear detection by eliminating sensor fluctuations and self-learning errors.

[0082] Optionally, in step S16, determining the clutch wear information based on the initial semi-clutch starting point information and the current semi-clutch starting point information includes:

[0083] Step S161, performing a difference operation on the current semi-linked starting point information and the initial semi-linked starting point information to obtain a first difference value;

[0084] Step S162, determining a first wear value based on the first difference and the friction plate information of the clutch;

[0085] Step S163: determining target wear information based on the first wear value and a plurality of wear thresholds.

[0086] Specifically, first, the current semi-clutch starting point information and the initial semi-clutch starting point information are subtracted to obtain a first difference value. Then, the first wear value is determined based on the first difference value and the friction plate information of the clutch. Finally, the wear level of the clutch is determined based on the first wear value and multiple wear thresholds. The specific calculation process of the first difference value is shown in Expression (4).

[0087] CluWA=(DynKP1-IntKP) / H*100 (4)

[0088] Among them, CluWA represents the first wear value; DynKP1 represents the current semi-clutch starting point value; IntKP represents the initial semi-clutch starting point value; H represents the initial thickness of the friction plate of the clutch.

[0089] Based on the above steps S161 to S163, the current semi-clutch starting point information and the initial semi-clutch starting point information are subtracted to obtain a first difference; the first wear value is determined based on the first difference and the friction plate information of the clutch; the target wear information is determined based on the first wear value and multiple wear thresholds, and the first difference is obtained by subtracting the current semi-clutch starting point information and the initial semi-clutch starting point information, which reflects the change of the semi-clutch starting point. The first wear value is calculated using the first difference and the friction plate information of the clutch, and the difference is converted into the actual physical wear amount. The accuracy of the detection result is improved by quantifying the difference and wear value.

[0090] Optionally, in step S163, the multiple wear thresholds include: a first wear threshold, and determining the target wear information based on the first wear value and the multiple wear thresholds includes:

[0091] Step S1631, in response to the first wear value being greater than the first wear threshold, determining that the target wear information is that the wear level of the clutch is the first wear level, wherein the first wear threshold is determined based on the friction plate information, and the first wear level is used to indicate that the clutch needs to be replaced.

[0092] Specifically, when the first wear value is greater than the first wear threshold, the target wear information is determined to be that the wear level of the clutch is the first wear level, that is, the wear level of the clutch is clutch failure, and the driver needs to be reminded to replace the clutch. For example, if the first wear threshold is 90, CluWA>90, then the target wear information is determined to be that the wear level of the clutch is the first wear level, that is, the wear level of the clutch is clutch failure, and the driver needs to be reminded to replace the clutch.

[0093] Based on the above step S1631, in response to the first wear value being greater than the first wear threshold, the target wear information is determined to be the wear level of the clutch being the first wear level, wherein the first wear threshold is determined based on the friction plate information, and the first wear level is used to indicate that the clutch needs to be replaced, thereby achieving the purpose of accurately and in real time detecting the degree of wear of the clutch, thereby achieving the technical effect of improving the efficiency of vehicle dry clutch wear detection and the accuracy of wear degree judgment, and further solving the technical problems of low efficiency of vehicle dry clutch wear detection and low accuracy of wear degree judgment in related technologies.

[0094] Optionally, in step S163, the multiple wear thresholds include: a second wear threshold, and determining the target wear information based on the first wear value and the wear threshold includes:

[0095] Step S1632, dividing the historical driving distance based on the preset driving distance to obtain a plurality of sub-historical driving distances;

[0096] Specifically, the historical driving distance is divided according to the preset vehicle driving distance information to obtain multiple sub-historical driving distances. For example, if the vehicle historical driving distance is 2000km and the preset vehicle driving distance is 200km, the vehicle historical driving distance is divided into 10 sub-historical driving distances, which are respectively denoted as S 200 , S 400 ,……,S 1800 , S 2000 .

[0097] Step S1633, determining a first wear value corresponding to each sub-historical driving distance, wherein the first wear value corresponding to each sub-historical driving distance is determined based on the initial semi-linked starting point information and the current semi-linked starting point information corresponding to each sub-historical driving distance;

[0098] In step S1633, the first wear threshold is determined based on the initial semi-linked starting point information and the current semi-linked starting point information corresponding to each sub-historical driving distance. For example, if the preset vehicle driving distance is 200km, a first wear value is recorded every 200km of vehicle driving, wherein each first wear value is determined based on the initial semi-linked starting point information and the current semi-linked starting point information corresponding to each sub-historical driving distance. In the process of the vehicle driving 2000km, the first wear values ​​corresponding to 10 sub-historical driving distances are recorded as CluWA respectively. 200 、CluWA 400 、……、CluWA 1800 、CluWA 2000 The calculation process of the first wear threshold is shown in expression (5).

[0099] W1=[(CluWA 1800 +CluWA 1600 +CluWA 1400 +…+CluWA 200 )] / 9 (5)

[0100] Step S1634, in response to the difference between the first wear values ​​corresponding to adjacent sub-historical driving distances being greater than the second wear threshold, determines that the target wear information is that the wear level of the clutch is the second wear level, wherein the second wear threshold is determined based on the first wear value corresponding to each sub-historical driving distance, and the wear degree of the second wear level is lower than the first wear level.

[0101] Specifically, when the difference between the first wear values ​​corresponding to the adjacent sub-historical driving distances is greater than the second wear threshold, the target wear information is determined to be that the wear level of the clutch is the first wear level, that is, the wear level of the clutch is abnormal wear, and the driver is reminded to perform maintenance in time. For example, W1=30, CluWA 1800 -CluWA2000 If the value is greater than the threshold value of 30, the target wear information is determined to be that the wear level of the clutch is the second wear level, and the instrument displays abnormal clutch wear to remind the driver to perform maintenance in time.

[0102] Based on the above steps S1632 to S1634, the historical driving distance is divided based on the preset driving distance to obtain multiple sub-historical driving distances; the first wear value corresponding to each sub-historical driving distance is determined, wherein the first wear value corresponding to each sub-historical driving distance is determined based on the initial semi-clutch starting point information and the current semi-clutch starting point information corresponding to each sub-historical driving distance; in response to the difference between the first wear values ​​corresponding to adjacent sub-historical driving distances being greater than the second wear threshold, the target wear information is determined to be the clutch wear level is the second wear level, wherein the second wear threshold is determined based on the first wear value corresponding to each sub-historical driving distance, and the wear level of the second wear level is lower than the first wear level, achieving the purpose of accurately and real-time detection of the clutch wear level, thereby achieving the technical effect of improving the efficiency of vehicle dry clutch wear detection and the accuracy of wear level judgment, thereby solving the technical problems of low vehicle dry clutch wear detection efficiency and low wear level judgment accuracy in related technologies. Optionally, the multiple wear thresholds also include: a third wear threshold, and the vehicle clutch wear detection method also includes:

[0103] Step S171, performing a difference operation on any candidate dynamic semi-linked starting point information and the initial semi-linked starting point information to obtain a second difference value;

[0104] Step S172, determining a second wear value based on the second difference and the friction plate information;

[0105] Step S173: in response to the second wear value being less than the third wear threshold, determining that the clutch has been replaced.

[0106] Specifically, a difference operation is performed between any one of the alternative dynamic semi-linkage starting point information and the initial semi-linkage starting point information to obtain a second difference value. The second wear value is determined based on the second difference value and the friction plate information. Taking the determination of the second wear value by one of the alternative dynamic semi-linkage starting point information, the initial semi-linkage starting point information and the friction plate information as an example, the calculation process of the second wear value CluWB is shown in Expression (6).

[0107] CluWB=(KPD Y -IntKP) / H*100 (6)

[0108] Wherein, CluWB represents the second wear value; KPD YIt represents any alternative dynamic semi-clutch starting point value, that is, when the lubricating oil temperature value is greater than the preset temperature value, the semi-clutch starting point information corresponding to the lubricating oil temperature value is determined as the alternative dynamic semi-clutch starting point information; IntKP represents the initial semi-clutch starting point value; H represents the initial thickness of the friction plate of the clutch.

[0109] Specifically, when the second wear value is less than the third wear threshold, it is determined that the clutch has been replaced, wherein the third wear threshold is determined based on the original thickness of the clutch friction plate. For example, the third wear threshold is set to 20, if CluWB<20, it means that the clutch has been replaced.

[0110] Based on the above steps S171 to S173, the dynamic semi-clutch starting point information and the static semi-clutch starting point information are subtracted to obtain a second difference; the second wear value is determined based on the second difference and the friction plate information; in response to the second wear value being less than the third wear threshold, it is determined that the clutch has been replaced. A more accurate clutch wear detection method is provided using difference operations and multiple wear thresholds, and the third wear threshold is used to determine whether the clutch has been replaced. When it is determined that the clutch has been replaced, the static semi-clutch starting point information and the dynamic semi-clutch starting point information of the target vehicle are re-acquired to re-determine the wear information of the clutch. This real-time update mechanism improves the timeliness and accuracy of the wear detection results.

[0111] Optionally, the vehicle clutch wear detection method further includes:

[0112] Step S181, in response to the clutch replacement operation, reacquire the static semi-clutch starting point information to determine the clutch wear information.

[0113] Specifically, when the clutch is replaced, it is necessary to re-acquire the static semi-clutch starting point information to determine the wear information of the clutch.

[0114] Based on the above step S181, in response to the clutch replacement operation, the static semi-clutch starting point information is reacquired to determine the wear information of the clutch. Reacquiring the static semi-clutch starting point information ensures that the data of the wear detection system matches the actual components, thereby improving the accuracy of wear detection.

[0115] Figure 2 FIG. 1 is a flow chart of another vehicle clutch wear detection method according to one embodiment of the present invention. Figure 2 As shown, the vehicle clutch wear detection method mainly includes the following execution steps:

[0116] Step S201, obtaining static semi-coordinated starting point information of the target vehicle;

[0117] Step S202, obtaining a lubricating oil temperature value in a transmission of the target vehicle during driving;

[0118] Step S203, in response to the lubricating oil temperature value being greater than a preset temperature value, determining the semi-cooperative starting point information corresponding to the lubricating oil temperature value as the candidate dynamic semi-cooperative starting point information;

[0119] Step S204, screening the candidate dynamic semi-linked starting point information based on the semi-linked starting point quantity constraint condition to obtain the dynamic semi-linked starting point information;

[0120] Step S205, performing an average operation on the static semi-coordinated starting point information and a second preset number of candidate dynamic semi-coordinated starting point information to obtain initial semi-coordinated starting point information;

[0121] Step S206, fitting the dynamic semi-linkage starting point information using a preset fitting algorithm to obtain a fitting equation;

[0122] Step S207, determining the current semi-linkage starting point information based on the independent variable and the fitting equation;

[0123] Step S208, performing a difference operation on the current semi-linked starting point information and the initial semi-linked starting point information to obtain a first difference value;

[0124] Step S209, determining a first wear value based on the first difference and the friction plate information of the clutch;

[0125] Step S210, in response to the first wear value being greater than the first wear threshold, determining that the target wear information is that the wear level of the clutch is the first wear level;

[0126] Step S211, dividing the historical driving distance based on a preset driving distance to obtain a plurality of sub-historical driving distances;

[0127] Step S212, determining a first wear value corresponding to each sub-historical driving distance;

[0128] Step S213 , in response to the difference between the first wear values ​​corresponding to adjacent sub-historical driving distances being greater than a second wear threshold, determining that the target wear information is that the wear level of the clutch is a second wear level.

[0129] Based on the above steps S201 to S213, the static semi-clutch starting point information and the dynamic semi-clutch starting point information of the target vehicle are obtained, the initial semi-clutch starting point information is determined based on the static semi-clutch starting point information and the dynamic semi-clutch starting point information, and the dynamic semi-clutch starting point information is fitted to determine the current semi-clutch starting point information, and finally the wear information of the clutch is determined based on the initial semi-clutch starting point information and the current semi-clutch starting point information, thereby achieving the purpose of accurately and real-time detection of the degree of wear of the clutch, thereby achieving the technical effect of improving the efficiency of vehicle dry clutch wear detection and the accuracy of wear degree judgment, and further solving the technical problems of low efficiency of vehicle dry clutch wear detection and low accuracy of wear degree judgment in related technologies.
