Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle clutch slip monitoring method and electronic equipment. Background Art

[0002] The clutch of a vehicle may wear out during use. Long-term wear will cause the clutch to polish. When the engine directly drives the vehicle, the clutch cannot effectively transmit the engine torque, and may even cause the engine to idle. Therefore, it is necessary to continuously monitor whether the clutch has a risk of slipping. At present, the monitoring of the clutch is usually completed in the vehicle-side controller, which occupies the computing resources of the vehicle-side controller and greatly reduces the operating efficiency of the vehicle-side controller. Summary of the invention

[0003] In view of this, the purpose of the present application is to propose a vehicle clutch slip monitoring method and electronic equipment to solve the problem that the clutch is monitored by a vehicle-side controller, resulting in reduced operating efficiency of the vehicle-side controller.

[0004] Based on the above purpose, the first aspect of the present application provides a vehicle clutch slip monitoring method, which is applied to a service end, comprising:

[0008] Optionally, determining whether the vehicle driving data satisfies a preset clutch slip condition includes:

[0009] Filtering the vehicle driving data according to the vehicle identification and the driving mode to determine target driving data;

[0010] Determine whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data.

[0011] The method of this embodiment can effectively reduce the data processing volume of the server and improve the data analysis and processing rate of the server.

[0012] Optionally, screening the vehicle driving data according to the vehicle identification and the driving mode to determine the target driving data includes:

[0013] The vehicle driving data is divided according to the vehicle identification, and the vehicle driving data belonging to the same vehicle is used as the first candidate driving data;

[0014] dividing the first candidate driving data according to the driving mode, and taking the first candidate driving data in the direct driving mode as the second candidate driving data;

[0015] The target driving data is determined from the second candidate driving data according to the target data collection time.

[0016] The target driving data determined in this embodiment is data for the same vehicle, data associated with determining whether the clutch has a slip risk, and data generated at the same time. Therefore, based on the target driving data, it is possible to accurately determine whether the clutch of the vehicle has a slip risk, thereby improving the accuracy of the slip risk determination.

[0017] Optionally, the second candidate driving data includes a candidate engine speed and a candidate transmission speed, and the target driving data includes a target engine speed and a target transmission speed;

[0018] The step of determining the target driving data from the second candidate driving data according to the target data collection time includes:

[0019] determining the target engine speed from among the candidate engine speeds according to the target data collection time;

[0020] The candidate transmission speed whose time difference between the data collection time and the target data collection time is less than a preset time difference threshold is used as the target transmission speed.

[0021] Through the method of this embodiment, when the engine speed and the transmission speed are generated at different times, data with close generation times can be determined as the target engine speed and the target transmission speed, thereby accurately analyzing whether there is a risk of clutch slippage and ensuring the accuracy of data screening.

[0022] Optionally, the second candidate driving data includes a candidate engine speed and a candidate transmission speed, and the target driving data includes a target engine speed and a target transmission speed;

[0023] The step of determining the target driving data from the second candidate driving data according to the target data collection time includes:

[0024] Determining the target gearbox speed from among the candidate gearbox speeds according to the target data collection time;

[0025] The candidate engine speed whose time difference between the data collection time and the target data collection time is less than a preset time difference threshold is used as the target engine speed.

[0026] Through the method of this embodiment, when the engine speed and the transmission speed are generated at different times, data with close generation times can be determined as the target engine speed and the target transmission speed, thereby accurately analyzing whether there is a risk of clutch slippage and ensuring the accuracy of data screening.

[0027] Optionally, the target driving data includes a target engine speed and a target transmission speed; and determining whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data includes:

[0028] For each data collection moment within a preset time period, calculating a speed difference between a target engine speed and a target gearbox speed corresponding to the data collection moment;

[0029] In response to the number of rotation speed differences greater than the preset difference threshold exceeding the preset number threshold, it is determined that the vehicle driving data satisfies the preset clutch slip condition.

[0030] By setting a preset quantity threshold in this embodiment, it is possible to avoid misjudgment of the risk of clutch slippage due to interference in the data collection or transmission process, thereby improving the accuracy of the judgment process and avoiding subsequent false alarms.

[0031] Optionally, the method for determining the preset difference threshold includes:

[0032] Collect historical engine speed and historical transmission speed of vehicles without faulty clutch;

[0033] determining a reference difference value according to the historical engine speed and the historical transmission speed;

[0034] The product of the reference difference and the preset safety factor is used as the preset difference threshold.

[0035] In this embodiment, multiplying the reference difference by the preset safety factor is equivalent to increasing the value of the reference difference, which can reduce the judgment error caused by data fluctuations. When the speed difference calculated in real time is greater than the preset difference threshold, it can be accurately determined that the preset clutch slip condition is met, eliminating the interference of data fluctuations, and then accurately determining that the clutch has a slip risk.

[0036] Optionally, the target driving data includes a target engine speed and a target transmission speed; and determining whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data includes:

[0037] For each data collection moment within a preset time period, calculating a speed difference between a target engine speed and a target gearbox speed corresponding to the data collection moment;

[0038] Calculate the rate of change of the speed difference between adjacent data collection moments within a preset time period;

[0039] In response to the fact that the rate of change of the rotational speed difference is positively correlated with the data collection time, it is determined that the vehicle driving data satisfies a preset clutch slip condition.

[0040] This embodiment monitors whether there is a risk of clutch slipping by the rate of change of the speed difference, so as to achieve accurate monitoring of the degree of clutch wear. When it is detected that the degree of clutch wear is becoming more and more serious, it is determined that the vehicle driving data meets the preset clutch slipping conditions, thereby being able to accurately determine that there is a risk of clutch slipping.

[0041] Optionally, the target driving data includes a target engine speed and a target transmission speed; and determining whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data includes:

[0042] Calculate a first change rate of the target engine speed at adjacent data collection moments within a preset time period;

[0043] Calculate a second change rate of the target gearbox speed at adjacent data collection moments within a preset time period;

[0044] In response to the first change rate being positively correlated with the data collection time, the second change rate being positively correlated with the data collection time, and the first change rate being greater than the second change rate, it is determined that the target driving data meets a preset clutch slip condition.

[0045] This embodiment jointly monitors whether there is a risk of clutch slipping through the rate of change of target engine speed and the rate of change of target transmission speed, thereby enabling accurate monitoring of the degree of clutch wear. When it is detected that the degree of clutch wear is becoming more and more serious, it is determined that the vehicle driving data satisfies the preset clutch slip conditions, thereby enabling accurate determination that there is a risk of clutch slipping.

[0046] Optionally, the method further includes:

[0047] Generate early warning information that the clutch has a risk of slipping, and send the early warning information to the vehicle end and / or the monitoring end.

[0048] This embodiment enables the user or the monitoring personnel at the monitoring end to accurately understand the working state of the clutch and formulate a subsequent maintenance plan in a timely manner. The risk of slipping can be predicted in advance before the clutch slips, and the vehicle can be maintained in advance, which reduces the subsequent maintenance costs of vehicle parts and improves user satisfaction.

[0049] Based on the same inventive concept, the present application also provides an electronic device, comprising a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method described in the first aspect when executing the computer program.

[0050] As can be seen from the above, the vehicle clutch slip monitoring method and electronic device provided by the present application are applied to the service end, and the vehicle driving data sent by the vehicle end is received by the service end to determine whether the vehicle driving data meets the preset clutch slip condition. If it meets the condition, it is determined that the clutch has a slip risk. The service end replaces the vehicle end controller to analyze the vehicle driving data to determine whether the clutch has a slip risk, that is, to predict the slip risk in advance, which can reduce the safety hazards of the vehicle. Since the vehicle driving data needs to be monitored in real time, the computing resources are continuously occupied during the monitoring process. Transferring the real-time monitoring process from the vehicle end controller to the service end can reduce the continuous occupation of the computing resources of the vehicle end controller, thereby avoiding the problem of reduced operating efficiency due to the shortage of computing resources of the vehicle end controller. At the same time, since the process from the beginning of clutch wear to the clutch slipping is a slow change, the service end can predict in advance whether there is a clutch slip risk by monitoring the wear of the clutch in real time. Therefore, even if the real-time monitoring process is transferred from the vehicle end controller to the service end, there will be no problem of vehicle driving safety caused by untimely monitoring. In summary, the method of the present application can not only timely monitor whether there is a risk of slipping of the clutch, but also reduce the occupation of computing resources of the vehicle-side controller, improve the performance of the vehicle-side controller, and thus enhance the user experience.

[0056] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0057] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0058] Currently, hybrid vehicles are at risk of coolant leakage in the transmission due to seal failure in low-temperature environments. Figure 1 A schematic diagram of the vehicle architecture of an embodiment of the present application is shown. Figure 1 As shown, the clutch is located between the engine and the gearbox. When the clutch is closed, the output torque of the engine can be transmitted to the gearbox, the engine can directly drive the wheel end, and the driving mode of the vehicle is direct drive mode. The clutch is connected to the input shaft of the gearbox, and the output shaft of the gearbox is connected to the reducer. After the coolant in the gearbox leaks, it will enter the cavity of the reducer and mix with the lubricating oil in the cavity of the reducer. After a period of time, the lubricating oil will emulsify, affecting the lubricating effect of the lubricating oil. Since the various components and transmission systems in the vehicle architecture are integrated, the cavities of each component are connected, and the emulsified lubricating oil in the reducer will circulate into the clutch, which will lead to a deterioration in the lubrication effect of the clutch, wear of the clutch, and eventually clutch polishing. When the engine directly drives the vehicle, due to the wear of the clutch, the clutch cannot effectively transmit the engine torque to the gearbox.

[0059] In order to prevent the above problems from occurring, it is necessary to continuously monitor the wear of the clutch in real time. When it is determined that the clutch is worn and there is a risk of slipping, the user or relevant monitoring personnel should be notified in time to maintain the vehicle's clutch and reduce vehicle safety hazards. At present, real-time monitoring of the clutch is completed through the vehicle-side controller. Since it is real-time monitoring, it is necessary to continuously occupy part of the computing resources of the vehicle-side controller, resulting in a decrease in the operating efficiency of the vehicle-side controller.

[0060] In view of this, the present application proposes a vehicle clutch slip monitoring method, which transfers the real-time monitoring of the clutch to the server for execution, thereby reducing the occupancy of the vehicle-side controller's computing resources and improving the operating efficiency of the vehicle-side controller.

[0061] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0062] The embodiment of the present application proposes a vehicle clutch slip monitoring method, which is applied to the service end, referring to Figure 2 , the method comprises the following steps:

[0063] Step 102: Receive the vehicle driving data sent by the vehicle end in real time.

[0064] Specifically, vehicle driving data is generated during the driving process of the vehicle, and the vehicle driving data is collected through the vehicle-mounted sensors. The vehicle driving data may include vehicle speed, acceleration, driving mode, engine speed, engine output torque, gearbox speed, etc. The vehicle end may send the vehicle driving data to the server end through a communication module, such as a telematics box (T-BOX), and the server end stores the vehicle driving data. Exemplarily, the server end may be a third-party service platform such as a telematics platform.

[0065] The vehicle driving data sent by the vehicle side is received in real time through the server side. The frequency of sending vehicle driving data can be set according to demand. For example, the vehicle side sends vehicle driving data to the server side once every 1s or 5s. By collecting vehicle driving data of multiple vehicles, the server side can perform statistical analysis on the driving status of each vehicle. When a vehicle is found to have driving safety hazards, the user or monitoring side can be informed in time to avoid driving safety problems of the vehicle.

[0066] Step 104: determine whether the vehicle driving data satisfies a preset clutch slip condition. If so, determine that there is a clutch slip risk.

[0067] Specifically, the service end determines whether the vehicle driving data meets the preset clutch slip condition based on the vehicle driving data. The preset clutch slip condition is used to characterize the conditions that the vehicle driving data needs to meet when the vehicle's clutch is at risk of slipping. When it is determined that the vehicle driving data meets the preset clutch slip condition, it is determined that the clutch is at risk of slipping. At this point, the clutch has been worn, and when the wear continues for a period of time, the clutch will slip. Whether the clutch can work normally directly affects whether the engine can directly drive the vehicle. By presetting the clutch slip condition, it is possible to predict in advance whether the clutch is at risk of slipping. Once a slip risk is found, the user or monitoring personnel can be notified in time to maintain the vehicle's clutch.

[0068] Furthermore, in the present application, the service end receives the vehicle driving data in real time and continuously determines whether the preset clutch slipping condition is met, rather than the vehicle-side controller continuously determining whether the preset clutch slipping condition is met. This can effectively reduce the occupation of the vehicle-side controller's computing resources and help improve the operating efficiency of the vehicle-side controller. Compared with the vehicle-side controller, the service end can provide more computing resources and has a higher computing rate, which is conducive to timely monitoring the risk of clutch slipping. At the same time, it takes a certain amount of time for the clutch to slip from the beginning of wear, and the wear of the clutch is a slow process. Therefore, transmitting the vehicle driving data to the service end for monitoring will not cause the problem of untimely judgment of the risk of slipping.

[0069] After receiving the driving data of multiple vehicles, the server performs statistical analysis on a large amount of driving data. It can not only conduct targeted driving status analysis on each vehicle, but also analyze vehicles of the same model to determine whether a certain vehicle or model has a fault or risk, and can also continuously monitor the maintenance effect after the vehicle is repaired. In this way, the statistical analysis of vehicle driving data by the server helps to optimize vehicle performance and improve user satisfaction.

[0070] Based on the above steps 102 to 104, this embodiment provides a vehicle clutch slip monitoring method, which is applied to the service end, and the service end receives the vehicle driving data sent by the vehicle end to determine whether the vehicle driving data meets the preset clutch slip condition. If it meets the condition, it is determined that the clutch has a slip risk. The service end replaces the vehicle end controller to analyze the vehicle driving data to determine whether the clutch has a slip risk, that is, to predict the slip risk in advance, which can reduce the safety hazards of the vehicle. Since the vehicle driving data needs to be monitored in real time, the computing resources are continuously occupied during the monitoring process. Transferring the real-time monitoring process from the vehicle end controller to the service end can reduce the continuous occupation of the computing resources of the vehicle end controller, thereby avoiding the problem of reduced operating efficiency due to the shortage of computing resources of the vehicle end controller. At the same time, since the process from the beginning of clutch wear to the occurrence of clutch slip is a slow change, the service end can predict in advance whether there is a clutch slip risk by monitoring the wear of the clutch in real time. Therefore, even if the real-time monitoring process is transferred from the vehicle end controller to the service end, there will be no problem of vehicle driving safety caused by untimely monitoring. In summary, the method of the present application can not only timely monitor whether there is a risk of slipping of the clutch, but also reduce the occupation of computing resources of the vehicle-side controller, improve the performance of the vehicle-side controller, and thus enhance the user experience.

[0071] Since the vehicle driving data uploaded from the vehicle side contains a large amount of data, some of which are irrelevant to determining whether there is a risk of clutch slippage. In order to reduce the amount of data processed by the server side, before the server side performs data analysis, a preliminary screening of the vehicle driving data is required to remove redundant or interfering data.

[0072] In some embodiments, determining whether the vehicle driving data satisfies a preset clutch slip condition includes:

[0073] The vehicle driving data is screened according to the vehicle identification and the driving mode to determine the target driving data; and whether the vehicle driving data satisfies a preset clutch slip condition is determined according to the target driving data.

[0074] Specifically, the server first cleans the vehicle driving data, including filtering duplicate data and invalid data. When the vehicle is in direct drive mode, the clutch is in a closed state. If the clutch is worn, it will affect the state of the active end and the load end of the clutch. The active end refers to the end where the clutch is connected to the engine, and the load end refers to the end where the clutch is connected to the gearbox. Since the vehicle driving data includes data of the vehicle in different states and different driving modes, it is also necessary to further filter out data related to clutch slippage from the vehicle driving data according to the driving mode, and remove data that is not related to determining whether the clutch is slipping.

[0075] In addition, the vehicle driving data also includes data of multiple vehicles. If you want to accurately monitor one of the vehicles, you also need to filter the vehicle driving data according to the vehicle identification, such as the vehicle identification number (VIN), and divide the vehicle driving data according to the vehicle identification, so that you can analyze the data belonging to the same vehicle in a targeted manner and accurately determine whether the vehicle has a risk of clutch slippage.

[0076] After filtering the vehicle driving data according to the vehicle identification and driving mode, the data obtained is used as the target driving data. Afterwards, the vehicle driving data is determined based on the target driving data to determine whether it meets the preset clutch slip conditions, which can effectively reduce the data processing volume on the server side and improve the data analysis and processing rate on the server side. Furthermore, when there is a risk of clutch slip, it can respond quickly and notify users and monitoring personnel, achieving the purpose of accurately monitoring the risk of clutch slip and timely feedback of the risk.

[0077] The method for determining the target driving data is described in detail below.

[0078] In some embodiments, the step of screening the vehicle driving data according to the vehicle identification and the driving mode to determine the target driving data includes:

[0079] The vehicle driving data is divided according to the vehicle identification, and the vehicle driving data belonging to the same vehicle is used as the first candidate driving data;

[0080] dividing the first candidate driving data according to the driving mode, and taking the first candidate driving data in the direct driving mode as the second candidate driving data;

[0081] The target driving data is determined from the second candidate driving data according to the target data collection time.

[0082] Specifically, the vehicle driving data is first divided according to the vehicle identification, and the vehicle driving data belonging to the same vehicle is used as the first candidate driving data. The first candidate driving data corresponds to the same vehicle, and when the first candidate driving data is analyzed, the driving data changes of the vehicle can be accurately known, and then whether the vehicle has a clutch slip risk can be accurately determined.

[0083] Secondly, since the first candidate driving data contains driving data of the vehicle in different driving modes, and the driving mode associated with clutch slip is the direct drive mode. Therefore, it is necessary to divide the first candidate driving data according to the driving mode, remove the data in the non-direct drive mode, and only retain the data in the direct drive mode to obtain the second candidate driving data. In this way, the interference data in the first candidate driving data is removed, ensuring that only the data that affects the risk of clutch slip is analyzed, and the data computing processing amount on the server side can be further reduced.

[0084] Furthermore, due to the large number of sensors on the vehicle side, different sensors may have different data collection cycles, and the timestamps corresponding to the various data received by the server are also different. When analyzing whether the clutch has a risk of slipping, the data should be sorted in chronological order, and the data generated at the same time should be analyzed to achieve an accurate analysis effect. Therefore, it is also necessary to divide the second candidate driving data according to the order of the data collection time. The target data collection time in this embodiment is the data collection time to be analyzed, and the target driving data obtained by screening from the second candidate driving data according to the target data collection time are all data generated at the target data collection time. The target driving data determined by this embodiment is data for the same vehicle, data associated with determining whether the clutch has a risk of slipping, and data generated at the same time. Therefore, based on the target driving data, it is possible to accurately determine whether the clutch of the vehicle has a risk of slipping, thereby improving the accuracy of the judgment of the risk of slipping.

[0085] It can be seen from the above embodiments that when judging whether the clutch is at risk of slipping, it is necessary to judge the data generated at the same time to ensure the accuracy of the judgment. However, due to the different periods of data collection by different sensors, the timestamps of the various data used to judge whether the clutch is at risk of slipping may be different. For example, the timestamps of the engine speed and the transmission speed contained in the target driving data are different. If the screening is performed at the same time, the engine speed and the transmission speed at the same generation time cannot be obtained. Therefore, the present application also provides a method for determining target driving data to solve the above problem.

[0086] In some embodiments, the second candidate driving data includes a candidate engine speed and a candidate transmission speed, and the target driving data includes a target engine speed and a target transmission speed;

[0087] The step of determining the target driving data from the second candidate driving data according to the target data collection time includes:

[0088] According to the target data collection time, the target engine speed is determined from the candidate engine speeds; and the candidate transmission speed whose time difference between the data collection time and the target data collection time is less than a preset time difference threshold is used as the target transmission speed.

[0089] In this embodiment, the vehicle driving data used to analyze whether the clutch is slipping includes the engine speed and the gearbox speed, and the gearbox speed refers to the input shaft speed of the gearbox. This is because the clutch is directly connected to the engine and the gearbox. When the clutch is closed, the output torque of the engine can be transmitted to the gearbox, and then transmitted to the wheel end through the gearbox to drive the vehicle. When the clutch is fault-free, the engine speed and the speed of the gearbox input shaft are equal. If the clutch is worn, it will affect the torque transmission effect of the clutch, resulting in a part of the engine's output torque unable to be transmitted to the gearbox side, which in turn causes a speed difference between the engine speed and the gearbox input shaft speed. Therefore, the engine speed and the gearbox speed are data that can directly reflect the degree of clutch wear. According to the engine speed and gearbox speed at the same time, it is possible to accurately analyze whether the clutch is at risk of slipping.

[0090] However, the engine speed and the transmission speed may be collected at different times, and there is no engine speed and transmission speed at the same time. At this time, the target engine speed is determined from the candidate engine speeds of the second candidate driving data according to the target data collection time, and the target engine speed refers to the engine speed generated at the target data collection time. The data collection time range can be determined based on the target data collection time and the preset time difference threshold. The upper limit of the data collection time range is determined by adding the preset time difference threshold to the target data collection time, and the lower limit of the data collection time range is determined by subtracting the preset time difference threshold from the target data collection time.

[0091] The target gearbox speed is determined from the candidate gearbox speeds of the second candidate driving data according to the data collection time range. In specific implementation, the data with the data collection time within the data collection time range is determined from the candidate gearbox speeds as the target gearbox speed. Among them, the preset time difference threshold can be determined according to the data collection cycle of the vehicle. Exemplarily, the preset time difference threshold is 0.5s. When the data collection time of the engine speed and the data collection time of the gearbox speed are both within the same data collection time range, since the data collection time is close, it will not affect the accuracy of the analysis of the slip risk. The engine speed and the gearbox speed within the same data collection time range are respectively determined as the target engine speed and the target gearbox speed. The target engine speed and the target gearbox speed can be used to analyze whether there is a slip risk for the clutch.

[0092] It should be noted that the above determination method is equivalent to first determining the target engine speed and then determining the target gearbox speed. In another specific implementation process, after determining the target data collection time, the target gearbox speed can also be determined from the candidate gearbox speeds according to the target data collection time, and then the candidate engine speed whose time difference between the data collection time and the target data collection time is less than the preset time difference threshold is used as the target engine speed. In other words, the target gearbox speed is determined first, and then the target engine speed is determined. The determination method is the same as above, and no further details are given here.

[0093] Through the method of this embodiment, when the engine speed and the transmission speed are generated at different times, data with close generation times can be determined as the target engine speed and the target transmission speed, thereby accurately analyzing whether there is a risk of clutch slippage and ensuring the accuracy of data screening.

[0094] After determining the target driving data, the server further determines whether the preset clutch slip condition is met based on the target driving data. The present application provides three different determination methods, which are described in detail below through different embodiments.

[0095] In a specific embodiment, the target driving data includes a target engine speed and a target transmission speed; and determining whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data includes:

[0096] For each data collection moment within a preset time period, calculating a speed difference between a target engine speed and a target gearbox speed corresponding to the data collection moment;

[0097] In response to the number of rotation speed differences greater than the preset difference threshold exceeding the preset number threshold, it is determined that the vehicle driving data satisfies the preset clutch slip condition.

[0098] Specifically, after receiving the vehicle driving data collected by the vehicle end within a period of time, the service end can divide all the vehicle driving data according to the receiving time. Divide a period of time according to the preset time to obtain multiple time periods, and the duration of each time period is equal to the preset time. For example, the preset time can be 10s. Within the preset time, each data collection moment can be regarded as a target data collection moment, and each target data collection moment corresponds to a target engine speed and a target gearbox speed. For each target data collection moment, the speed difference between the target engine speed and the target gearbox speed is calculated, and the speed difference can be the absolute value of the difference between the target engine speed and the target gearbox speed.

[0099] After calculation, multiple speed differences are obtained. If the number of speed differences greater than the preset difference threshold among the multiple speed differences exceeds the preset data threshold, it is determined that the preset clutch slip condition is met, that is, the vehicle has a clutch slip risk. Among them, the preset difference threshold represents the critical speed difference at which there is a clutch slip risk. When the speed difference is greater than the preset difference threshold, the clutch may have a slip risk.

[0100] In order to avoid errors in judgment caused by errors in the data transmission or collection process, this embodiment simultaneously judges multiple speed difference values ​​calculated within a preset time length. If the number of speed difference values ​​greater than the preset difference threshold is large, it means that the interference is not caused by the data transmission or collection process, and it can be determined that the vehicle driving data meets the clutch slip condition. The preset difference threshold and the preset number threshold can be set according to actual conditions. Exemplarily, the preset difference threshold is 30r / min, and the preset number threshold is 80% of the total number of speed differences. If the total number of speed differences calculated within the preset time length is 10, the preset number threshold is 8. When the number of speed differences exceeding 30r / min among the 10 speed differences is greater than 8, it is determined that the preset clutch slip condition is met.

[0101] By setting a preset quantity threshold in this embodiment, it is possible to avoid misjudgment of the risk of clutch slippage due to interference in the data collection or transmission process, thereby improving the accuracy of the judgment process and avoiding subsequent false alarms.

[0102] The preset difference threshold can be used to determine whether there is a risk of clutch slippage. The accuracy of the preset difference threshold will affect the accuracy of subsequent clutch slippage risk judgment. Therefore, the determination of the preset difference threshold is an important step. The method of determining the preset difference threshold is described below through a specific embodiment.

[0103] In some embodiments, the method for determining the preset difference threshold value includes:

[0104] Collect historical engine speed and historical transmission speed of vehicles without faulty clutch;

[0105] determining a reference difference value according to the historical engine speed and the historical transmission speed;

[0106] The product of the reference difference and the preset safety factor is used as the preset difference threshold.

[0107] Specifically, the preset difference threshold is determined based on the data of the vehicle with a fault-free clutch. The fault-free clutch refers to a clutch that has no wear. The historical data of the vehicle with a fault-free clutch is used as a standard reference value, and then the preset difference threshold is formulated. The historical engine speed and the historical gearbox speed of the vehicle with a fault-free clutch are collected, and the collection time of the historical engine speed and the historical gearbox speed is one-to-one. According to the difference between the historical engine speed and the historical gearbox speed, a reference difference is determined. Since the historical engine speed and the historical gearbox speed collected at different times are different, in this embodiment, the speed difference with the largest calculated value is used as the reference difference. The reference difference represents the maximum speed difference between the historical engine speed and the historical gearbox speed when the fault-free clutch is operating normally. If the speed difference exceeds the reference difference, it means that the clutch has a certain wear and the clutch is at risk of slipping. Under normal circumstances, due to the accuracy of the sensor itself or the different sampling frequencies of data collection, there will be a small difference between the historical engine speed and the historical gearbox speed. Usually, the difference will not exceed 5% of the historical engine speed or 5% of the historical gearbox speed.

[0108] In addition, since the reference difference is a critical value for judging whether the clutch has a risk of slipping, in order to avoid fluctuations during judgment, after determining the reference difference, the reference difference is multiplied by a preset safety factor. Among them, the preset safety factor is a value greater than 1, such as 1.5. Multiplying the reference difference by the preset safety factor is equivalent to increasing the value of the reference difference, which can reduce the jump in the judgment result caused by data fluctuations. When the speed difference calculated in real time is greater than the preset difference threshold, it can be accurately determined that the preset clutch slip condition is met at this time, eliminating the interference of data fluctuations, and then accurately determining that the clutch has a risk of slipping.

[0109] In another specific embodiment, the target driving data includes a target engine speed and a target transmission speed; and determining whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data includes:

[0110] For each data collection moment within a preset time length, the speed difference between the target engine speed and the target transmission speed corresponding to the data collection moment is calculated; the change rate of the speed difference between adjacent data collection moments within the preset time length is calculated; in response to the change rate of the speed difference being positively correlated with the data collection moment, it is determined that the vehicle driving data meets the preset clutch slip condition.

[0111] Specifically, after receiving the vehicle driving data collected by the vehicle end within a period of time, the service end can divide all the received vehicle driving data according to the receiving time. A period of time is divided according to the preset time to obtain multiple time periods, and the duration of each time period is equal to the preset time. For example, the preset time is 10s. Within the preset time, each data collection moment can be regarded as a target data collection moment, and each target data collection moment corresponds to a target engine speed and a target gearbox speed. For each target data collection moment, the speed difference between the target engine speed and the target gearbox speed is calculated, and the speed difference can be the absolute value of the difference between the target engine speed and the target gearbox speed.

[0112] After calculation, multiple speed differences are obtained. Within the preset time, the speed difference change rate between adjacent data collection moments is calculated. If the speed difference change rate increases with the increase of data collection time, it means that the speed difference change rate has an increasing trend with time, that is, the speed difference between the engine speed and the gearbox speed is getting bigger and bigger, and the efficiency of the clutch in transmitting the engine torque is getting lower and lower, indicating that the degree of wear of the clutch is getting more and more serious. It can be determined that the vehicle driving data meets the preset clutch slip condition and there is a risk of clutch slip.

[0113] This embodiment monitors whether there is a risk of clutch slipping by the rate of change of the speed difference, so as to achieve accurate monitoring of the degree of clutch wear. When it is detected that the degree of clutch wear is becoming more and more serious, it is determined that the vehicle driving data meets the preset clutch slipping conditions, thereby being able to accurately determine that there is a risk of clutch slipping.

[0114] In another specific embodiment, the target driving data includes a target engine speed and a target transmission speed; and determining whether the vehicle driving data satisfies a preset clutch slip condition according to the target driving data includes:

[0115] Calculate a first change rate of the target engine speed at adjacent data collection moments within a preset time period;

[0116] Calculate a second change rate of the target gearbox speed at adjacent data collection moments within a preset time period;

[0117] In response to the first change rate being positively correlated with the data collection time, the second change rate being positively correlated with the data collection time, and the first change rate being greater than the second change rate, it is determined that the target driving data meets a preset clutch slip condition.

[0118] Specifically, after receiving the vehicle driving data collected by the vehicle end within a period of time, the service end can divide all the received vehicle driving data according to the receiving time. Divide a period of time according to the preset time to obtain multiple time periods, and the duration of each time period is equal to the preset time. For example, the preset time is 10s. Within the preset time, each data collection moment can be regarded as a target data collection moment, and each target data collection moment corresponds to a target engine speed and a target gearbox speed.

[0119] Within a preset time period, a first change rate of the target engine speed at adjacent data collection moments and a second change rate of the target transmission speed at adjacent data collection moments are calculated. The first change rate can represent the change trend of the target engine speed, and the second change rate can represent the change trend of the target transmission speed.

[0120] When the clutch is worn and the degree of wear becomes more and more serious, the speed difference between the engine speed and the gearbox speed will become larger and larger. When the engine output torque increases, the engine speed will increase accordingly. Since the ability of the clutch to transmit torque is reduced, although the speed of the gearbox will also increase, the increase will be significantly less than the increase in the engine speed, which will lead to an increasing speed difference. Therefore, according to this principle, in this embodiment, the changes in the target engine speed and the changes in the target gearbox speed are monitored separately to determine whether there is a risk of clutch slippage. If the first change rate increases with the increase in data collection time, the second change rate increases with the increase in data collection time, and the first change rate is greater than the second change rate, it can be determined that the target driving data meets the preset clutch slip condition, the degree of clutch wear gradually increases, and the clutch is at risk of slippage.

[0121] This embodiment jointly monitors whether there is a risk of clutch slipping through the rate of change of target engine speed and the rate of change of target transmission speed, thereby enabling accurate monitoring of the degree of clutch wear. When it is detected that the degree of clutch wear is becoming more and more serious, it is determined that the vehicle driving data satisfies the preset clutch slip conditions, thereby enabling accurate determination that there is a risk of clutch slipping.

[0122] Through the aforementioned several embodiments of the present application, three methods for determining whether the vehicle driving data meets the preset clutch slip conditions are provided. When selecting a judgment method, the server can select one or several of them to jointly judge whether there is a risk of clutch slipping. When several methods are selected for joint judgment, the probability of misjudgment when one method is used for judgment can be reduced. If the judgment results generated by the two judgment methods are different, a third method can be used to make another judgment to determine whether there is a risk of clutch slipping.

[0123] After the service determines that the vehicle is at risk of clutch slippage, it needs to send a warning message to the user or monitoring personnel to promptly notify the user to repair the vehicle and reduce vehicle safety hazards.

[0124] In some embodiments, the method further comprises:

[0125] Generate early warning information that the clutch has a risk of slipping, and send the early warning information to the vehicle end and / or the monitoring end.

[0126] Specifically, after determining that the clutch is at risk of slipping, the service end generates a warning message based on the real-time vehicle driving data received, and sends the warning message to the vehicle end to notify the user, and can also send the warning message to the monitoring end to notify the monitoring personnel. The warning message can include the data analysis results of determining whether the clutch is at risk of slipping, so that the user or the monitoring personnel at the monitoring end can accurately understand the working status of the clutch and formulate subsequent maintenance plans in a timely manner. Predicting the risk of slipping in advance before the clutch slips, and then performing maintenance and maintenance on the vehicle in advance, reduces the subsequent maintenance costs of vehicle components and improves user satisfaction.

[0127] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
