Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle monitoring technology, and in particular to a method, device, equipment and medium for locating an illegal vehicle maintenance point. Background Art

[0002] At present, buying a car is a common thing. When the money is not sufficient or the funds are temporarily tight, the car purchase policies launched by car dealers such as 0 down payment and three years of interest-free have attracted many car buyers to buy cars with loans. When buying a car with a loan, the car dealer or bank will have the risk of not being able to recover the loan. In order to reduce this risk, T-Box is generally installed on the vehicle. Through T-Box, remote monitoring or remote locking instructions can be issued to urge the lender to repay on time.

[0003] However, in recent years, with the upgrading of technology of illegal vehicle repair institutions, these institutions have destroyed the vehicle hardware equipment or software information to make the vehicle uncontrollable by the above remote monitoring and locking instructions. This makes it impossible for dealers or banks to locate and remotely control the vehicle, and without the deterrent of remote locking, some borrowers will maliciously owe money, resulting in the dealers or banks being unable to recover the loans, causing significant losses to the dealers or banks.

[0041] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0042] An embodiment of the present application relates to a method for locating an illegal vehicle maintenance point. The implementation details of the method for locating an illegal vehicle maintenance point of this embodiment are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.

[0043] The specific process of the method for locating illegal vehicle maintenance points in this embodiment can be as follows: Figure 1 As shown, including:

[0044] Step 101, obtaining engine running time and mileage of multiple different vehicles at different times within a preset time period.

[0045] For example, 500,000 vehicles are randomly selected and all CAN data reported by each vehicle through T-BOX in the past year (including the vehicle's engine running time and mileage), as well as the data collection time and data reporting time of each of these data, are obtained.

[0046] In one example, after obtaining the above data, the following preprocessing operations are first performed on it, including:

[0047] (1) Analyze these data and flatten the analyzed data according to the data reporting time.

[0048] (2) Clean the flattened data to remove the jump data. Jump means that the vehicle's T-BOX reports an invalid data at a certain moment and then reports normal data. At this time, the invalid data is removed as jump data and then stored in the database to avoid affecting the subsequent location of illegal maintenance points. For example, the vehicle's mileage is A1, A2, A3, A4, A5, ..., A10 for 10 consecutive mileages, where A1 to A5 increase regularly, A2-A1<1km, A3-A2<1km, A4-A3<1km, A5-A4<1km, and A6-A5>5km, and A7-A5<1km, then A6 can be determined as jump data and A6 can be removed.

[0049] Step 102: Screen out vehicles that meet the target conditions from multiple different vehicles. The target conditions are that the engine running duration of the vehicle decreases and then gradually increases within a preset time period, or the driving mileage of the vehicle becomes 0 or 0.5 within a preset time period.

[0050] Specifically, circularly query the CAN data reported by each vehicle, and screen out vehicles whose engine running duration does not increase continuously or whose reported driving mileage shows data 0 or 0.5. The fact that the engine running duration does not increase continuously or the driving mileage becomes 0 or 0.5 means that the vehicle is likely to be illegally damaged.

[0051] In the specific implementation, for screening vehicles whose engine running duration does not increase continuously: Under normal circumstances, the engine running duration of a vehicle increases with time. If, after a certain moment, the engine running duration data decreases and then starts to increase again, it means that the vehicle is likely to be damaged at that moment. For example, if a vehicle has 10 consecutive engine running durations of A1, A2, A3, A4, A5,..., A10, where A1 to A5 increase regularly, 0km < A2 - A1 < 1km, 0km < A3 - A2 < 1km, 0km < A4 - A3 < 1km, 0km < A5 - A4 < 1km, while A6 - A5 < 0km, and 0km < A7 - A6 < 1km, then it can be determined that the engine running duration of this vehicle does not increase continuously, and this vehicle meets the target conditions.

[0052] For screening vehicles whose driving mileage shows data 0 or 0.5: Under normal circumstances, the driving mileage of a vehicle increases with time. When the vehicle is illegally damaged, the driving mileage will become 0 or 0.5. For example, if a vehicle has 10 consecutive driving mileages of B1, B2, B3, B4, B5,..., B10, where B1 to B5 increase regularly, 0 < B2 - B1 < 5m, 0 < B3 - B2 < 5m, 0 < B4 - B3 < 5m, 0 < B5 - B4 < 5m, and B6 to B10 become 0, 0.5, 0, 0, 0, then it can be determined that the driving mileage of this vehicle shows data 0 or 0.5, and this vehicle meets the target conditions.

[0053] In some embodiments, the above target conditions include any one of the following: the absolute value of the difference between the engine running durations of two adjacent vehicles is greater than or equal to a first preset threshold; the vehicle continuously shows that the driving mileage becomes 0 or 0.5 and the number of times it becomes 0 or 0.5 is greater than or equal to a second preset threshold.

[0054] For example, for each vehicle, determine whether the absolute value of the difference between two adjacent engine running time data among all the engine running time data reported by it is greater than 50. If so, confirm that the vehicle meets the target conditions. The reporting frequency of CAN data (engine running time and mileage) is generally about 5s. Under normal circumstances, the absolute value of the difference between two consecutive engine running times reported by a vehicle will not be greater than 50. If it is greater than 50, it means that the vehicle was illegally damaged at the time of reporting the second data of these two data. Alternatively, for each vehicle, determine whether there are 5 consecutive reports of mileage of 0 or 0.5 among all the mileage data reported by it. If so, confirm that the vehicle meets the target conditions to prevent the jump data from affecting the positioning of subsequent illegal maintenance points.

[0055] In a specific example, the engine running time of the vehicle is arranged in ascending order according to the data reporting time. All data are traversed in sequence. For example, if 10 consecutive engine running times are A1, A2, A3, A4, A5, ..., A10, the engine running time of the vehicle that has been illegally damaged (wrong example) and the engine running time of the vehicle in normal conditions are as follows (normal example):

[0056] Correct examples: 0<|A2-A1|<5 & 0<|A3-A2|<5 & 0<|A4-A3|<5

[0057] Incorrect example: 0<|A2-A1|<5 & |A3-A2|>50 & |A4-A3|>50

[0058] Incorrect example: 0<|A2-A1|<5 & |A3-A2|>50 & 0<|A4-A3|<5

[0059] The mileage of the vehicle is arranged in ascending order according to the time of data reporting. All data are traversed in sequence. For example, if 10 consecutive mileages are B1, B2, B3, B4, B5, ..., B10, the mileage of the vehicle that has been illegally damaged (wrong example) and the mileage of the vehicle in normal conditions are as follows (normal example):

[0060] Incorrect example: B1=0, B2=0, B3=0, B4=0, B5=123, B6=0

[0061] Correct example: B1=0, B2=0, B3=0, B4=0, B5=0, B6=0.5

[0062] Correct example: B1=0, B2=0, B3=0.5, B4=0, B5=0.5, B6=0

[0063] Correct example: B1=0, B2=0.5, B3=0, B4=0, B5=0.5, B6=0

[0064] Step 103, obtaining GPS data of the selected vehicles at the moment when the engine running time decreases and then starts to increase, or at the moment when the mileage becomes 0 or 0.5.

[0065] Specifically, when randomly selecting 500,000 vehicles and obtaining all CAN data (including the vehicle's engine running time and mileage) reported by each vehicle through T-BOX in the past year, as well as the data collection time and data reporting time of these data, all GPS data (including latitude and longitude, direction, and vehicle speed, etc.) reported by these vehicles through T-BOX, as well as the data collection time and data reporting time of these data, are simultaneously obtained. When there is a vehicle that meets any of the above target conditions among all the randomly selected vehicles, the moment when the engine running time of the above vehicle decreases and then starts to increase, or the moment when the mileage becomes 0 or 0.5, is obtained, and the GPS data corresponding to this moment is obtained from all the obtained GPS data.

[0066] In one example, the GPS data includes the latitude and longitude, direction, and speed of the vehicle. First, the direction and speed data are removed, and only the latitude and longitude data are retained as the final GPS data.

[0067] In some embodiments, the moment corresponding to the latter engine running time of two adjacent engine running times is selected, and GPS data of the moment corresponding to the latter engine running time of the two adjacent engine running times is obtained; or, the moment when the mileage becomes 0 or 0.5 for the first time in a case where the mileage becomes 0 or 0.5 continuously occurs is selected, and GPS data of the moment when the mileage becomes 0 or 0.5 for the first time in a case where the mileage becomes 0 or 0.5 continuously occurs is obtained.

[0068] For example, if when traversing the vehicle's engine running time data, the engine running time satisfies that the absolute value of the difference between two adjacent engine running time data is greater than 50, then the data reporting time of the second data that satisfies the absolute value of the difference greater than 50 is recorded. As in the correct example above, the data reporting time of the engine time at point A3 is recorded. The recorded information may be the frame number: LB666666, and the data reporting time: 2023-07-11 12:22:22. If when traversing the vehicle's mileage data, the mileage is 0 or 0.5 for 5 consecutive times, then the data reporting time of the first mileage being 0 or 0.5 is recorded. The recorded information may be the frame number: LB666666, and the data reporting time: 2023-07-11 12:22:22.

[0069] At this time, according to the above data reporting time: the data reporting time of the second data whose absolute value of the difference between two adjacent engine running time data is greater than 50, or the data reporting time of the first mileage of 5 consecutive mileages being 0 or 0.5, obtain the GPS data of the vehicle at the corresponding time.

[0070] In some embodiments, the moment when the engine running time decreases and then starts to increase and the moment when the mileage becomes 0 or 0.5 are taken as the target moment. If the GPS data is not obtained at the target moment, the GPS data of the vehicle is obtained at the moment when the absolute value of the difference with the target moment is within the preset time range. For example, if the GPS data of the vehicle is not obtained at the above data reporting time (i.e., the data reporting time of the second data of the data whose absolute value of the difference between two adjacent engine running time data is greater than 50, or the data reporting time of the first mileage of 5 consecutive mileages being 0 or 0.5), the GPS data of the time point (i.e., the target moment) whose absolute value of the difference from the data reporting time point is within 300 seconds is obtained. Since the GPS data and the CAN data (i.e., the engine running time and the mileage) belong to different messages, the data reporting time may be different. If the GPS data cannot be queried according to the CAN data reporting time, it is also acceptable to query the GPS data closest to the reporting time.

[0071] In a specific implementation, when the GPS data of the vehicle is acquired at a time when the absolute value of the difference with the target time is within a preset time range, the GPS data corresponding to the time closest to the target time is selected.

[0072] In a specific example, assuming that the recorded data reporting time is C1, if the GPS data of the vehicle at that time point can be obtained based on the C1 time point and the frame number, the GPS data is recorded, and the recorded content may be the frame number: LB666666, data reporting time: 2023-07-11 12:22:22, longitude: 106.34567, latitude: 35.54678.

[0073] In another specific example, assuming that the recorded data reporting time is C1, if the GPS data of the vehicle at that time point cannot be obtained based on the C1 time point and the frame number, check whether there is GPS data within 5 minutes before and after C1. If there is one piece of data, record the GPS data. If there are multiple pieces of data, select the GPS data closest to the C1 time point. The recorded content can be the frame number: LB666666, data reporting time: 2023-07-11 12:22:22, longitude: 106.34567, latitude: 35.54678.

[0074] Step 104, determining the area where the illegal vehicle maintenance point is located based on the GPS data.

[0075] Specifically, by obtaining the GPS data of the moment when the engine running time decreases and then starts to increase, or when the mileage becomes 0 or 0.5, that is, the GPS data of the vehicle when the vehicle is illegally damaged, the location where the vehicle was illegally damaged can be determined, that is, the area where the vehicle is illegally repaired.

[0076] In one example, if the GPS data is GPS data corresponding to the time closest to the target time (i.e., the time when the engine running time decreases and then starts to increase, or the time when the mileage becomes 0 or 0.5), the area where the illegal vehicle maintenance point is located is determined based on the GPS data corresponding to the time closest to the target time.

[0077] In some embodiments, after obtaining the GPS data of the moment corresponding to the latter engine running time of two adjacent engine running times, or the GPS data of the moment when the mileage becomes 0 or 0.5 for the first time in a situation where the mileage becomes 0 or 0.5 continuously, the area where the illegal vehicle maintenance point is located is determined based on the data.

[0078] In a specific implementation, the GPS data of this embodiment is the longitude and latitude of the area where the vehicle is located, that is, the area where the illegal vehicle maintenance point is located is determined according to the longitude and latitude of the vehicle. First, the location of each vehicle is obtained according to the longitude and latitude of all vehicles that meet the target conditions. If the distance between the locations of two vehicles is less than or equal to the third preset threshold, the longitude and latitude of the two vehicles are determined to be similar; if the number of vehicles with similar longitude and latitude is greater than or equal to the fourth preset threshold, the area where the illegal vehicle maintenance point is located is determined according to the longitude and latitude. For example, according to the longitude and latitude of all vehicles that meet the target conditions, the locations of the two vehicles are obtained as points A and B, and the straight-line distance between points A and B is not greater than 50m, which means that the longitude and latitude of points A and B are similar. If the number of such similar longitudes and latitudes in the longitude and latitude judgment corresponding to all vehicles that meet the target conditions is greater than or equal to 10, the longitude and latitude information is recorded, and the area where the illegal vehicle maintenance point is located is determined based on it.

[0079] In one example, a circular area with a radius of 50m is defined as an illegal vehicle maintenance point with the latitude and longitude determined above as the center of the circle.

[0080] In some embodiments, after an illegal vehicle repair site is determined, it is designated as a high-risk area and a fence is set up, an alarm is set up for the fence, and the vehicle to be monitored is bound to the fence, so that an alarm message can be sent to the dealer in a timely manner when the vehicle enters the fence.

[0081] In this embodiment, under normal circumstances, the engine running time and mileage of a vehicle gradually increase over time. When a vehicle is modified by illegal means, the engine running time of the vehicle will be reset to zero, and the mileage will be continuously reported as 0 or 0.5. Therefore, by obtaining the engine running time and mileage of multiple different vehicles at different times within a preset time period, and screening out vehicles that meet the target conditions (the engine running time of the vehicle decreases and then gradually increases within the preset time period, or the mileage of the vehicle becomes 0 or 0.5 within the preset time period), it is possible to For vehicles that have been illegally modified, the GPS data of the screened vehicles can be obtained at the moment when the engine running time decreases and then starts to increase, or when the mileage becomes 0 or 0.5, that is, the GPS data of the vehicle just being illegally modified. The GPS data can be used to indicate the location of the illegal modification site of the vehicle (that is, the illegal vehicle maintenance site). Therefore, the area where the vehicle's illegal maintenance site is located can be determined based on the GPS data. When another vehicle approaches the illegal vehicle maintenance site, the dealer will be warned in advance to control the vehicle before it is damaged, thereby reducing the losses of the dealer and the bank.

[0082] The step division of the various methods above is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of the present invention. Adding insignificant modifications or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the protection scope of the invention.

The target conditions are that the engine running time of the vehicle decreases and then gradually increases within a preset time period, or the mileage of the vehicle becomes 0 or 0.5 within a preset time period.
