Detailed Description
At present, the phenomenon that the actual driving mileage of a vehicle is abnormally modified (namely, the phenomenon that an odometer is tampered) is a phenomenon specific to the domestic second-hand vehicle market, and the vehicle with the tampered odometer is called a meter-adjusting vehicle. In mature used-vehicle markets such as the united states, european union, japan, etc., illegal modification of vehicle odometer data is strictly prohibited, thereby concealing the actual vehicle information. The domestic second-hand vehicle market is not perfect, no legal regulation and no clear text forbidding on meter exchanging vehicles are provided, and no penalty measures are provided. Due to the fact that prices of second-hand vehicles of the same type with different mileage are different greatly, a large number of meter-adjusting vehicles appear in domestic second-hand vehicle markets.
Therefore, in the process of detecting the used cars, the detection of the actual driving mileage of the used cars is an important detection link. The actual driving mileage of the used vehicle directly reflects the mechanical structure service life of the vehicle and the working state of the electronic equipment, and has great influence on the trading price of the used vehicle. The actual driving mileage of the vehicle is generally detected by reading the mileage recorded on the odometer of the used vehicle by a detector, and determining whether the mileage recorded on the odometer is adjusted or not by combining the mileage with the conditions of steering wheel wear, tire wear, and accelerator pedal wear of the used vehicle determined by the detector. However, the detection method of the meter-adjusting vehicle completely depends on the subjective judgment of the detection personnel by self experience, and the conditions of missed judgment and wrong judgment are easy to occur. Therefore, the detection of the actual driving mileage of the vehicle is always lack of comprehensive and objective technical means.
When the vehicle is in use, each time a fault occurs and a fault code is generated, an Electronic Control Unit (ECU) records the fault code of the vehicle to form a freeze frame.
The freeze frame includes: the vehicle comprises a frame number, a frozen frame identification, time information and mileage information of the vehicle.
And the frozen frame identifier is used for uniquely identifying the frozen frame.
And the time information is used for recording the forming time of the freeze frame.
And the mileage information is used for recording the driving mileage data of the vehicle when the freeze frame is formed.
The freeze frame is one of contents specified by an On-Board Diagnostic System (OBD) standard protocol, and therefore, the freeze frame of the vehicle can be acquired by using an existing OBD Diagnostic apparatus.
The freeze frame is data reserved when the vehicle has a fault, is not easy to be tampered and has high usability. Based on this, the method, the device and the electronic equipment for determining the shunting schedule car provided by the embodiment of the application obtain the time information and the mileage information with the preset format by processing the freezing frame of the car, combine the mileage information with the same freezing frame identification with the time information with the preset format to obtain the freezing frame mileage information, then judge whether the car is the shunting schedule car according to the time sequence recorded in the time information with the preset format in the freezing frame mileage information and the sequencing result obtained by sequencing the freezing frame mileage information, do not need manual participation in the whole detection process of the shunting schedule car detection, can objectively determine whether the car is the shunting schedule car, and the mileage information recorded in the freezing frame is not easy to change, can objectively reflect the car mileage, and avoids the misjudgment and missed judgment of the shunting schedule car as much as possible, the reliability and the reliability of the meter adjusting vehicle detection are improved.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Example 1
The execution main body of the shunting car judging method provided by the embodiment is the server.
The server can be connected with the OBD diagnostic instrument to receive the freeze frame acquired by the OBD diagnostic instrument from the OBD of the vehicle, process the freeze frame and determine whether the vehicle is a shunting car.
The server may adopt any computing device capable of processing the freeze frame and judging the shunting cars according to the time information and the mileage information obtained by processing in the prior art, and details are not repeated here.
In order to judge whether the vehicle is a meter-dispatching vehicle, the server stores vehicle information of the vehicle which needs to be judged by the meter-dispatching vehicle.
The vehicle information of the vehicle is input into the server by the worker.
The vehicle information includes, but is not limited to: the frame number of the vehicle, the date of delivery, and the vehicle style.
Referring to a flowchart of a method for determining a scheduled vehicle shown in fig. 1, the present embodiment provides a method for determining a scheduled vehicle, which includes the following specific steps:
In step 100, the server may obtain a freeze frame from the OBD diagnostic apparatus.
In order to process the frozen frame and obtain the time information and the mileage information in the frozen frame, respectively, in the step 100, the following steps (1) to (3) may be performed:
(1) acquiring a first keyword related to mileage and a second keyword related to time;
(2) inputting a frozen frame of a vehicle and an acquired first keyword into an NLP (non-line segment) model, processing the frozen frame of the vehicle and the first keyword by using the NLP model, and obtaining time information in the frozen frame from the frozen frame of the vehicle;
(3) inputting a frozen frame of a vehicle and an acquired second keyword into an NLP model, processing the frozen frame of the vehicle and the second keyword by using the NLP model, and obtaining mileage information in the frozen frame from the frozen frame of the vehicle.
In step (1) above, the first keywords related to mileage include, but are not limited to: kilometers, meters, and kilometers.
The second keywords related to time include, but are not limited to: time, date, ambient data-date, and global real time clock.
In the step (2), the NLP model may be run in a server.
The method comprises the steps of inputting a frozen frame of a vehicle and an acquired first keyword into a natural language analysis model, processing the frozen frame of the vehicle and the first keyword by using the natural language analysis model, and obtaining time information in the frozen frame from the frozen frame of the vehicle, which is the prior art, is not repeated here.
In one embodiment, the format of the time information in the freeze frame can be represented by the following table 1:
TABLE 1
The time information unit S in table 1 means seconds. The time information name "time" in the format 1, the time information name "date" in the format 4, and the time information name "environment data — date" in the format 5 all refer to the time at which the freeze frame to which the time information belongs is formed. The time information name "time" in format 2, the time information name "time" in format 3, and the time information name "global real-time clock" in format 6 all refer to the total number of seconds from 1970 to 00 minutes 00 seconds 01 month 00 hour 00 second to the time when the freeze frame to which the time information belongs is generated.
Table 1 above, which may also be referred to as a time information format list, is cached in the server.
In the step (3), inputting the frozen frame of the vehicle and the obtained second keyword into a natural language analysis model, and processing the frozen frame of the vehicle and the second keyword by using the natural language analysis model is the prior art, and is not repeated here.
And processing the frozen frame of the vehicle and the first key word by using the natural language analysis model to obtain information related to mileage.
Due to abnormal conditions such as equipment failure, communication failure, data analysis error and the like, the information related to the mileage obtained by processing the frozen frame of the vehicle and the first keyword by the NLP model may include invalid data.
Further, the server may adopt the following data cleaning methods to clean invalid data in the information related to the mileage to obtain the time information in the freeze frame:
a) and according to the determined distance unit, eliminating the target item with the distance unit as abnormal data.
The distance units include, but are not limited to: kilometers, and meters.
b) And filtering the too big and too small target items according to a fixed threshold value.
In one embodiment, target items smaller than 0 and larger than 1000000 in the target item may be culled as exception data.
c) And uniformly converting the distance units of the target items reserved after the methods a and b are executed.
Such as: for convenience of subsequent processing, the distance units of the target items may be unified into one kilometer.
d) And according to a preset value type, removing the target items which are not in the preset value type as abnormal data.
In one embodiment, the preset value type may be, but is not limited to: integer numbers, floating point numbers, and/or fractions.
e) And carrying out 2-system, 8-system, 10-system or 16-system data conversion on the target item to unify the expression form of the target item.
f) And converting the target item according to the byte sequence stored by the computer.
After invalid data in the information related to mileage is cleaned by using the above-mentioned methods a) to f), the mileage information in the freeze frame can be obtained.
Similar to the time information, the mileage information may be cached in the server in the form of a table.
The mileage information includes: and the frozen frame identification and the driving mileage data of the vehicle when the frozen frame is formed.
The time information in the freeze frame has a plurality of time formats, and if the time formats are not processed, the time information in different time formats cannot be sorted, so that after the processing of the time information is completed, the following step 102 can be continuously executed to process the obtained time information.
And 102, processing the time information to obtain the time information with a preset format.
The time information with the preset format means that time data in the processed time information has the following format: year/month/day-hour: dividing into: and second.
In order to obtain the time information with the preset format, the step 102 may perform the following steps (1) to (4):
(1) acquiring a time information format list, and a time information name and a time information unit of the time information; the time information format list is used for recording a time data format corresponding to a time information name and a time information unit;
(2) determining a time data format corresponding to a time information name and a time information unit of the time information from a time information format list;
(3) acquiring the format of time data in the time information with the preset format;
(4) and when the time data format corresponding to the time information name and the time information unit of the time information is not consistent with the time data format in the time information with the preset format, converting the time data format of the time information into the time data format in the time information with the preset format to obtain the time information with the preset format.
The processing flow of the time information described in the above steps (2) to (4) is explained by the following example:
when the time information name of the obtained time information is "time" and the time information unit is "second", the server can determine from the time information format list that the time data format is XXXX in format 3, which corresponds to the time information name being "time" and the time information unit being "second".
As can be seen from the above, the format of the time data in format 3 is different from the format of the time data recorded in the time information having the preset format, and therefore, the server determines that the time information is obtained after 00 minutes 00 seconds XXXX seconds on 01, 00 h.01, 1970 of greenwich mean time. Then, the server can calculate the time data in the time information based on greenwich mean time 1970, 01, 00 hours, 00 minutes and 00 seconds and time data XXXX seconds.
The format of the calculated time data is a format of time data recorded in the time information having a preset format: year/month/day-hour: dividing into: and second.
When the server determines that the time information name of the time information and the time data corresponding to the time information unit are in the time data format of format 2 or format 6, the above calculation and conversion of the time data of format 3 can be adopted, and the process of obtaining the time information with the preset format is similar, and is not repeated here.
When the server determines that the time information name of the time information and the time data corresponding to the time information unit are in the time data format of format 1, format 4 or format 5, the time data of format 1, format 4 or format 5 need to be converted into the format of the time data recorded in the time information with the preset format, and the time data can be obtained without calculation.
After converting the time information into the time information having the preset format through the above step 102, the following step 104 may be continuously performed to obtain the freeze frame mileage information.
And 104, combining the mileage information with the same freeze frame identification and the time information with a preset format to obtain freeze frame mileage information.
In the step 104, any existing technology capable of combining tables may be adopted, and the mileage information having the same freeze frame identifier and the time information having the preset format are combined together, which is not described herein again.
And 106, sequencing the freeze frame mileage information according to the time sequence recorded in the time information with the preset format in the freeze frame mileage information to obtain a sequencing result.
And 108, when the sorting result indicates that the mileage information recorded by the mileage information of the freeze frame which is sorted later in the mileage information of the freeze frame is less than the mileage information recorded by the mileage information of the freeze frame which is sorted earlier in the mileage information of the freeze frame, determining that the vehicle is a shunting vehicle.
In order to determine whether the vehicle is a meter-adjusting vehicle, the step 108 may perform the following steps (1) to (4):
(1) when the mileage information recorded by the mileage information of the freezing frame which is ranked later is less than the mileage information recorded by the mileage information of the freezing frame which is ranked earlier in the ranked mileage information of the freezing frame, calculating the difference value between the mileage information recorded by the mileage information of the freezing frame which is ranked earlier and the mileage information recorded by the mileage information of the freezing frame which is ranked later;
(2) when the difference value is larger than the mileage difference value threshold value, determining that the vehicle is a meter adjusting vehicle;
(3) when the difference is smaller than or equal to the mileage difference threshold value, determining that the vehicle is an unadjusted meter vehicle;
(4) and when the mileage information recorded by the mileage information of the freezing frame which is ranked later in the ranked freezing frame mileage information is larger than the mileage information recorded by the mileage information of the freezing frame which is ranked earlier in the ranked freezing frame mileage information, determining that the vehicle is an unregulated vehicle.
In the step (2), the mileage difference threshold is cached in the server.
In one embodiment, the mileage difference threshold may be set to any value between 0 and 500, which is not described in detail herein.
Through the process described in the steps (1) to (3), if the mileage information after the ranking is less than the mileage information before the ranking, but if the difference between the mileage information recorded by the mileage information of the frozen frame before the ranking and the mileage information recorded by the mileage information of the frozen frame after the ranking is less than or equal to the mileage difference threshold, it is indicated that the mileage difference is small, which may be caused by data errors, in this case, the vehicle cannot be determined as a meter-adjusting vehicle, but if the difference is greater than the mileage difference threshold, it is indicated that the mileage difference is large, and the mileage of the vehicle is likely to be adjusted, so the vehicle can be determined as the meter-adjusting vehicle.
In summary, in the method for determining a meter-dispatching vehicle provided in this embodiment, time information and mileage information in a preset format are obtained by processing a freeze frame of a vehicle, the mileage information with the same freeze frame identifier and the time information in the preset format are combined to obtain freeze frame mileage information, and then according to a time sequence recorded in the time information in the preset format in the freeze frame mileage information, whether the vehicle is a meter-dispatching vehicle is determined by a sequencing result obtained by sequencing the freeze frame mileage information, compared with a manner in which a tester reads the mileage recorded on the odometer of a second-hand vehicle in the related art and combines with a tire wear condition of the second-hand vehicle determined by the tester to determine whether the mileage recorded on the meter is adjusted, the whole meter-dispatching vehicle detection process does not need manual participation, whether the vehicle is the meter-adjusting vehicle or not can be objectively judged, the mileage information recorded in the freezing frame is not easy to change, the vehicle mileage can be objectively reflected, the condition that the meter-adjusting vehicle is misjudged and missed in judgment is avoided as much as possible, and the reliability and the credibility of meter-adjusting vehicle detection are improved.
