[0025] Figure 1 is a flowchart of a vehicle transmission system wear condition monitoring method according to an embodiment of the present application, as shown in Figure 1 The method comprises the following steps:

[0026] Step S102, in the case that the vehicle enters a preset coasting state, acquiring current vehicle condition information, driving condition information and driving environment information of the vehicle.

[0027] The current vehicle condition information is used to represent the current hardware vehicle condition information of the vehicle, and the driving condition information is used to represent the driving parameter information generated by the vehicle driving in the preset coasting state.

[0028] The transmission system mentioned above can refer to a series of components and electrical and mechanical devices that transmit power to the wheels. The transmission system can include but is not limited to clutches, gearboxes, drive shafts, differentials, and drive wheels. The clutch can be used to connect and disconnect the contact between the engine and the transmission system, so that the vehicle can stop or start. The gearbox can be used to change the speed and torque of the engine output to adapt to different driving conditions and speed requirements. The drive shaft can transmit the power of the engine to the rear wheels or four-wheel drive system of the vehicle. The differential can be used to balance the speed difference between the wheels to ensure the stability of the vehicle when turning. The drive wheel can push the vehicle forward through the friction between the tire and the ground. Monitoring and maintaining the transmission system can ensure that the vehicle maintains good performance and reliability during use. The specific structure of the transmission system can be determined according to actual needs, which is not limited here.

[0029] The vehicle mentioned above can refer to a fuel vehicle, a new energy vehicle, etc. with a transmission system. The specific type of the vehicle can be determined according to actual needs, which is not limited here.

[0030] The preset coasting state mentioned above can refer to a pre-set vehicle coasting state. The determination conditions for the vehicle entering the preset coasting state can include but are not limited to the vehicle switching to neutral, the vehicle brake pedal being in the released state, the vehicle being in the straight running state, the current vehicle speed being greater than the preset vehicle speed, and the vehicle current driving road condition information, etc. The determination conditions for the vehicle entering the preset coasting state can be determined according to actual needs, which is not limited here.

[0031] The current vehicle condition information mentioned above can refer to the hardware condition information of the vehicle, which can include the state of the mechanical components, the transmission system, the power system, etc. of the vehicle. The working state of each component of the vehicle can be monitored by sensors and fed back to the system for analysis and judgment. The current vehicle condition information can include but is not limited to the current speed of the engine, the tire pressure of each tire of the vehicle, the temperature condition of each component of the vehicle, etc. The current vehicle condition information can be determined according to actual needs, which is not limited here.

[0032] The driving condition information mentioned above can refer to various driving parameter information generated by the vehicle in the preset coasting state. It can include but is not limited to speed, acceleration, etc. The driving condition information can help the monitoring system analyze the running condition of the vehicle in the coasting state. By monitoring and analyzing the driving condition information, the monitoring system can timely discover the faults and wear of the transmission system and perform maintenance and repair in advance to ensure the safety and performance of the vehicle. The driving condition information can be determined according to actual needs, which is not limited here.

[0033] For example, when the vehicle enters the preset coasting state, the monitoring system can record the speed change, acceleration change, wheel speed, etc. of the vehicle in real time, and by analyzing these data, the monitoring system can determine whether the transmission system of the vehicle is working normally and whether there is abnormal wear phenomenon. For example, if the vehicle has abnormal acceleration change or speed fluctuation in the coasting state, it may mean that the transmission system has a problem and needs further inspection and repair.

[0034] The above-mentioned driving environment information can refer to the environmental conditions in which the vehicle is located during driving, which can include but is not limited to road conditions, temperature, humidity, wind force, etc. The driving environment information can affect the driving state and performance of the vehicle. When monitoring the wear condition of the vehicle transmission system, the environmental conditions of the vehicle can be considered. For example, if the vehicle is driving on a road with poor road conditions, such as a bumpy road or a muddy road, such environmental conditions will cause the vehicle transmission system to bear greater impact and friction. The specific type of driving environment information can be determined according to actual needs, which is not limited here.

[0035] In an optional embodiment, when the vehicle meets the condition of entering the preset coasting state during driving, it can be determined that the vehicle enters the preset coasting state. The current hardware vehicle condition information of the vehicle can be obtained through various sensors and monitoring devices, which can help to determine the overall condition and performance of the vehicle. After the vehicle enters the preset coasting state, the driving condition information generated during driving of the vehicle can be monitored, which can reflect the actual driving condition of the vehicle in the coasting state. At the same time, the driving environment information of the vehicle can be monitored, which can include road conditions, temperature, humidity, etc. The current vehicle condition information, driving condition information and driving environment information obtained through the above steps can help to analyze the wear condition of the vehicle transmission system. By monitoring these information, the problems of the transmission system can be found in time for maintenance and repair, prolonging the service life of the vehicle and ensuring driving safety. The current vehicle condition information and driving condition information of the vehicle, as well as the driving environment information of the vehicle, are comprehensively considered when monitoring the wear condition of the vehicle transmission system, which facilitates subsequent comprehensive evaluation of the working state and wear condition of the transmission system.

[0036] Step S104, determining a set of actual coasting accelerations of the vehicle in the preset coasting state based on the driving condition information.

[0037] The above-mentioned set of actual coasting accelerations can refer to the actual coasting accelerations of the vehicle in the entire process of the preset coasting state, and can also include a plurality of actual accelerations obtained by dividing the entire process of the preset coasting state according to time intervals or speed intervals. The set of actual coasting accelerations can be determined according to actual needs, which is not limited here.

[0038] In an optional embodiment, the actual coasting acceleration set of the vehicle in the preset coasting state can be determined based on the driving condition information. Specifically, the collected data can be pre-processed, which can include noise removal, data alignment, and the like, to ensure the accuracy and integrity of the data. The actual coasting acceleration of the vehicle in the coasting state can be calculated based on the speed change and time information of the vehicle. The calculated actual coasting acceleration set can be analyzed, and the wear condition of the vehicle can be evaluated and predicted through statistical analysis, machine learning algorithms, and the like. Through the above steps, the actual coasting acceleration set of the vehicle in the preset coasting state can be determined based on the driving condition information, which can reflect the actual coasting resistance of the vehicle in the preset coasting state, facilitating subsequent monitoring and analysis of the wear condition of the vehicle transmission system.

[0039] In step S106, the reference coasting acceleration set of the vehicle in the preset coasting state is determined based on the current vehicle condition information and the driving environment information.

[0040] The reference coasting acceleration set mentioned above can refer to the reference coasting acceleration corresponding to the transmission system of the vehicle being within the normal wear degree range. The reference coasting acceleration data in the reference coasting acceleration set can be obtained through computer simulation software simulation calculation, and can also be obtained through actual vehicle test field testing. The data in the reference coasting acceleration set can be determined according to actual needs, which is not limited here.

[0041] In an optional embodiment, the reference coasting acceleration set of the vehicle in the preset coasting state can be determined based on the current vehicle condition information and the driving environment information. Specifically, the reference coasting acceleration set of the vehicle in the preset coasting state can be determined through computer simulation software simulation or actual vehicle test field testing. In the computer simulation software, a mathematical model of the vehicle transmission system can be established to simulate the running state of the vehicle under different conditions, including acceleration, deceleration, turning, and the like. Through analysis of the simulation results, the reference coasting acceleration set can be determined. In the actual vehicle test field testing, sensors and data acquisition equipment can be installed on the vehicle to record the running data of the vehicle under different conditions, such as acceleration, speed, fuel consumption, and the like. Through analysis and processing of the experimental data, the reference coasting acceleration set of the vehicle in the preset coasting state can be determined. Subsequently, by comparing the running data of the actual vehicle with the reference coasting acceleration set, the wear condition of the vehicle transmission system can be evaluated, and maintenance measures can be taken in a timely manner to ensure the safety and performance of the vehicle.

[0042] In step S108, the actual coasting acceleration set and the reference coasting acceleration set are compared to obtain a target comparison result.

[0043] The target comparison result can be used to represent the difference between the actual coasting acceleration set and the reference coasting acceleration set. The comparison method can use statistical methods such as mean, variance, etc. Through comparison, the target comparison result, i.e., the difference between the actual coasting acceleration and the reference coasting acceleration, can be obtained.

[0044] In an optional embodiment, the actual coasting acceleration set and the reference coasting acceleration set are compared, and data analysis and processing techniques such as statistical analysis, data mining or machine learning algorithms, etc. can be used for data processing and analysis. The target comparison result can be determined by the ratio of corresponding elements in the actual coasting acceleration set and the reference coasting acceleration set, or by the difference of corresponding elements in the actual coasting acceleration set and the reference coasting acceleration set. The determination method of the target comparison result can be determined according to actual needs, which is not limited here. The target comparison result is obtained, which facilitates the subsequent determination of the wear condition of the vehicle transmission system according to the comparison result. If there is a significant deviation between the actual coasting acceleration and the reference coasting acceleration, it may indicate that the vehicle transmission system is worn or faulty, and needs to be repaired or replaced. Through the above steps, the wear condition of the vehicle transmission system can be monitored and diagnosed, problems can be found and handled in time, and the normal operation and safety of the vehicle can be ensured.

[0045] Specifically, the comparison of the actual coasting acceleration set and the reference coasting acceleration set can be completed through data analysis and algorithm calculation. The coasting acceleration data of the vehicle at different speeds can be collected, and these data can be sorted into an actual coasting acceleration set, and then a reference coasting acceleration set can be established. The target comparison result can be obtained by comparing the difference between the actual coasting acceleration set and the reference coasting acceleration set, and then the wear condition of the vehicle transmission system can be determined. For example, the target vehicle collects coasting acceleration data at different speeds during actual coasting test, and obtains an actual coasting acceleration set [2.5 m / s^2, 3.0 m / s^2, 2.8 m / s^2]. The reference coasting acceleration set [3.0 m / s^2, 3.2 m / s^2, 3.1 m / s^2] is obtained by statistical analysis of the reference coasting data of the same model vehicle. By comparing the two sets, the difference between the actual coasting acceleration and the reference coasting acceleration can be calculated, and the target comparison result is obtained, which is used to determine the wear condition of the vehicle transmission system.

[0046] In step S110, the wear condition of the vehicle transmission system is determined based on the target comparison result.

[0047] In an optional embodiment, the wear condition of the transmission system of the vehicle can be determined based on the target comparison result. According to the target comparison result, if the actual coasting acceleration is significantly different from the reference coasting acceleration, it indicates that the transmission system of the vehicle may have wear or failure. According to this judgment, the components of the transmission system, such as the clutch and the gearbox, can be further checked to determine the specific wear condition. Assuming that the comparison result of the actual coasting acceleration and the reference coasting acceleration shows that the actual coasting acceleration is significantly lower than the reference coasting acceleration, it indicates that the transmission system of the vehicle may have wear. For example, it is found through further inspection that the clutch of the vehicle is severely worn, resulting in reduced transmission efficiency. Therefore, the wear condition of the transmission system of the vehicle is determined based on the comparison result, and corresponding maintenance and repair work is performed.

[0048] In the embodiment of the present application, a monitoring method for the wear condition of the transmission system of a vehicle is provided, which comprises: obtaining current vehicle condition information, driving condition information and driving environment information of the vehicle when the vehicle enters a preset coasting state, wherein the current vehicle condition information is used to represent the current hardware vehicle condition information of the vehicle, and the driving condition information is used to represent the driving parameter information generated by the vehicle when driving in the preset coasting state; determining a set of actual coasting accelerations of the vehicle in the preset coasting state based on the driving condition information; determining a set of reference coasting accelerations of the vehicle in the preset coasting state based on the current vehicle condition information and the driving environment information; comparing the set of actual coasting accelerations with the set of reference coasting accelerations to obtain a target comparison result; and determining the wear condition of the transmission system of the vehicle based on the target comparison result. It is easy to note that the monitoring method for the wear condition of the transmission system of the vehicle proposed in the present application can be automatically implemented during actual driving of the vehicle. The current vehicle condition information, the driving condition information and the driving environment information of the vehicle are comprehensively considered. The set of actual coasting accelerations of the vehicle in the preset coasting state is determined based on the driving condition information, which can accurately reflect the performance of the vehicle in the actual resistance coasting process. The set of reference coasting accelerations of the vehicle in the preset coasting state is determined based on the current vehicle condition information and the driving environment information, which can establish the resistance coasting reference information of the vehicle in the ideal state. The target comparison result can be obtained by comparing the difference between the set of actual coasting accelerations and the set of reference coasting accelerations, and the wear condition of the transmission system of the vehicle can be determined. The monitoring and diagnosis of the wear condition of the transmission system of the vehicle can be realized, problems can be found and handled in time, the normal operation and safety of the vehicle can be ensured, and the technical problem of low efficiency in monitoring the wear condition of the transmission system of the vehicle in the related art is solved.

[0049] Optionally, the method further comprises: determining that the vehicle enters the preset coasting state when the vehicle switches to neutral, the brake pedal of the vehicle is in the released state, and the current vehicle speed is greater than a preset vehicle speed during driving of the vehicle.

[0050] The preset vehicle speed can be a preset vehicle speed threshold. The vehicle can be determined to enter the preset coasting state only when the vehicle speed meets the preset vehicle speed condition, so as to ensure that the vehicle can maintain coasting for a certain period of time in the preset coasting state, and facilitate subsequent monitoring of the wear degree of the vehicle transmission system. For example, the preset vehicle speed can be 100 km / h, 80 km / h, or the like. The preset vehicle speed can be determined according to actual needs, which is not limited here.

[0051] In an optional embodiment, in the vehicle transmission system, the neutral position indicates that there is no direct mechanical connection between the engine and the gearbox, and the vehicle can be switched to the neutral position by shifting the gear lever or the shift piece to the neutral position. When the brake pedal is in the released state, it indicates that the driver does not step on the brake pedal, and the vehicle is not braked. The monitoring system can monitor the vehicle speed in real time through the sensors of the vehicle, and determine whether the current vehicle speed is greater than the preset vehicle speed. For example, when the above conditions are met at the same time, the monitoring system can determine that the vehicle has entered the preset coasting state. For example, during the driving process of a vehicle, the driver shifts the gear lever to the neutral position, does not step on the brake pedal, and the vehicle speed exceeds the preset vehicle speed. At this time, the vehicle sensors detect these states, and the monitoring system determines that the vehicle has entered the preset coasting state. The determination conditions for the vehicle entering the preset coasting state can also be determined according to actual needs, for example, the vehicle can also be in a straight driving state, the road slope of the vehicle is less than a preset slope threshold, and the like, which is not limited here.

[0052] Optionally, the actual coasting acceleration set of the vehicle in the preset coasting state is determined based on the driving condition information, including: obtaining real-time vehicle speed information in the driving condition information, wherein the real-time vehicle speed information is used to represent real-time vehicle speed information of the vehicle when coasting after being subjected to resistance in the preset coasting state; determining at least one actual coasting acceleration of the vehicle in the preset coasting state based on the real-time vehicle speed information and a preset time interval; and generating the actual coasting acceleration set based on the at least one coasting acceleration.

[0053] The preset time interval can be a preset time interval, which can be 1 s or 0.2 s after the vehicle enters the preset coasting state, or the like. The preset time interval can be determined according to actual needs, which is not limited here.

[0054] In an optional embodiment, when it is determined that the vehicle is in the preset coasting state, real-time vehicle speed information in the driving condition information can be obtained, the speed information of the vehicle can be obtained in real time through a sensor or a vehicle-mounted device on the vehicle, the actual coasting acceleration of the vehicle can be determined based on the real-time vehicle speed information and a preset time interval, the acceleration of the vehicle in the time interval can be obtained by calculating the difference between the speeds at two adjacent time points and dividing the time interval. This acceleration value can represent the actual acceleration of the vehicle in the preset coasting state; the actual coasting acceleration set can be generated based on at least one coasting acceleration, the coasting acceleration values calculated in a plurality of time intervals can be recorded and sorted to form an actual coasting acceleration set, and the actual coasting acceleration set can be used to analyze the acceleration change of the vehicle to determine the wear condition of the transmission system of the vehicle. By analyzing the actual coasting acceleration set, the acceleration change of the vehicle in the coasting state can be understood, and the wear condition of the transmission system of the vehicle can be determined. If the acceleration suddenly increases or is unstable, it may indicate that the transmission system has a problem and needs to be repaired and maintained in time. Through the above method, the wear condition of the transmission system of the vehicle can be monitored and warned.

[0055] Optionally, the current vehicle condition information at least includes one of the following: current tire pressure information, engine oil temperature information and transmission oil temperature information of the vehicle, and the driving environment information at least includes one of the following: road slope information, road type information and weather condition information of the vehicle driving; the reference coasting acceleration set of the vehicle in the preset coasting state is determined based on the current vehicle condition information and the driving environment information, including: matching the current vehicle condition information and the driving environment information with the preset reference coasting acceleration set to obtain the reference coasting acceleration set, wherein the preset reference coasting acceleration set is used to represent a set of reference data of coasting acceleration obtained by a pre-prepared resistance coasting test.

[0056] In an optional embodiment, the current tire pressure information, engine oil temperature information and transmission oil temperature information of the vehicle can be acquired through the vehicle-mounted sensors; the road slope information, road type information and weather condition information of the vehicle can also be acquired through the vehicle-mounted sensors or through the external data source connected to the vehicle; a set of reference data of the coasting acceleration can be obtained according to the resistance coasting test performed in advance, which can represent the acceleration range of the preset coasting state of the vehicle under different vehicle conditions and driving environments; then the current vehicle condition information and driving environment information can be matched with the set of reference coasting accelerations, for example, assuming that a vehicle is driving in high-temperature weather, the engine oil temperature and the transmission oil temperature are high, and the vehicle is driving on a mountain road with a large road slope, the system can match the reference acceleration data suitable for high-temperature weather and mountain driving in the set of preset coasting accelerations according to the information acquired by the vehicle-mounted sensors, and can match the current vehicle condition information and driving environment information of the vehicle with the set of preset reference coasting accelerations to obtain the set of reference coasting accelerations suitable for the current situation.

[0060] The above-mentioned preset threshold can refer to a threshold value for measuring the target comparison result, which can be determined according to actual needs, and is not limited here.

[0062] The following describes an optional application scenario of the technical solution proposed in the present application. After a long time of operation, the power transmission devices such as the transmission system, the rotating shaft bearing and the brake caliper of the user's vehicle can be worn or damaged, which can increase the energy consumption and the risk of vehicle failure, and even can cause safety accidents. At present, there is a lack of effective means to monitor the above problems. The technical solution proposed in the present application can monitor the vehicle coasting resistance in real time through the online monitoring means of the vehicle resistance, intelligently judge whether the coasting resistance exceeds a reasonable range, and remind the user to repair in time in the case of abnormality, thereby reducing the energy loss caused by high friction resistance and avoiding vehicle failure and safety accidents.

[0063] Specifically, the coasting test can be carried out on a standard test field to obtain the coasting acceleration of the vehicle in a normal state. Specifically, the vehicle can be run to 120 km / h after the engine is fully warmed up, at which time the vehicle is kept in neutral (N) and the accelerator pedal and brake pedal are released, the vehicle is gradually coasted to below 20 km / h, and the acceleration at each vehicle speed is calculated. The resistance monitoring can be carried out in the following steps: a, determining whether the vehicle is running between 20-120 km / h and the current trip has exceeded 5 km; b, determining whether the vehicle has traveled more than 100 km since the last monitoring; c, determining whether the current road slope is within ±0.1 according to the vehicle acceleration sensor; d, determining whether the current road is an asphalt road according to the front video camera of the vehicle; e, determining the current weather condition, whether the wind speed is less than 1 m / s, whether it is a sunny day, and whether the temperature and humidity differ from the standard state of the test field by less than 5% according to the internet information; f, determining whether the current altitude is less than 1000 m according to the vehicle air pressure sensor; g, determining whether the four tire pressures are within the normal range; h, if it is a hybrid vehicle, determining whether it is currently driving in pure electric mode; i, if it is a gasoline vehicle, determining whether the engine oil temperature, water temperature and transmission oil temperature are all higher than 70°C. The specific data of the above parameters can be set according to actual needs, which is not limited here; it can be set that if any of the above conditions is not met, the monitoring is exited; when the above conditions are completely met, the state of the driver's accelerator pedal and brake pedal can be monitored until the driver releases both pedals, at which time the vehicle speed change is recorded until any of the above conditions is not met; if the coasting duration is greater than or equal to 5 seconds, the monitoring is successful, and the vehicle coasting resistance can be determined; if the coasting duration is less than 5 seconds, the monitoring fails, and the monitoring is restarted.

[0064]

[0065] The accelerations at the above five time points can be calculated: a1=(V2-V1) / 3.6; a2=(V3-V2) / 3.6; a3=(V4-V3) / 3.6; a4=(V5-V4) / 3.6; a5=(V6-V5) / 3.6; the accelerations at the above five points can be compared with the accelerations corresponding to the vehicle speeds of the standard test field, respectively; if the average value of the differences of the five accelerations is greater than 0.1 m / s 2 , the instrument panel needs to display "vehicle resistance abnormality" to remind the user to detect and repair, if the average value of the differences of the five accelerations is less than or equal to 0.1 m / s 2Therefore, it is proved that the whole vehicle sliding resistance is normal, and no reminding is needed, the application realizes intelligent judgment of whether the vehicle and the environment are suitable for sliding acceleration test, judges whether the user vehicle exists abnormity according to the user vehicle sliding acceleration, intelligently reminds the user vehicle resistance abnormity, avoids friction energy consumption waste, reduces vehicle failure, and avoids safety accidents.
