Description

Mileage detection method and device, electronic equipment and computer storage medium

Technical Field

The present invention relates to the field of automotive technologies, and in particular, to a method and an apparatus for mileage detection, an electronic device, and a computer storage medium.

Background

With the development of the used-car market, the used-car trading business is continuously increased. Since the total driving mileage of the vehicle affects the service life of components such as an engine and a transmission, and further affects the transaction price of the vehicle, in order to increase sales profits, the total driving mileage of the vehicle may be tampered by the vehicle owner or the middleman, which may damage the benefit of the consumer.

In order to guarantee the benefit of consumers, the total mileage of a vehicle is usually checked during a transaction to detect whether the total mileage of the vehicle is tampered. At present, a method for detecting whether the total driving mileage of a vehicle is tampered generally includes that a professional estimates the driving mileage of the vehicle according to personal experience and the wear degree of the vehicle, compares the driving mileage with the mileage displayed on a vehicle instrument panel, and finally determines whether the total driving mileage of the vehicle is tampered according to a comparison result.

However, since the above method is easily affected by human factors, a large deviation may be generated between the estimated mileage and the actual mileage of the vehicle, so that it is impossible to accurately detect whether the total mileage of the vehicle is falsified.

Disclosure of Invention

The embodiment of the application discloses a mileage detection method, a mileage detection device, electronic equipment and a computer storage medium, so as to improve the accuracy of detecting whether the total mileage of a vehicle is tampered.

In a first aspect, an embodiment of the present application provides a mileage detection method, including: acquiring first mileage information recorded by a vehicle to be detected through an instrument panel; acquiring a verification result of an electronic control unit of the vehicle to be detected, wherein the verification result is used for describing the matching degree of the vehicle to be detected and the electronic control unit; under the condition that the check result indicates that the matching degree meets a first preset threshold value, acquiring second mileage information recorded by the vehicle to be detected through the electronic control unit; and determining a first detection result of the vehicle to be detected according to the first mileage information and the second mileage information, wherein the first detection result is used for determining whether the total driving mileage of the vehicle to be detected is tampered.

In an embodiment of the application, the first mileage information includes total mileage information displayed on an instrument panel of the vehicle to be detected. The electronic control unit is in communication connection with the vehicle to be detected, and the total driving mileage of the vehicle to be detected can be calculated according to the rotating speed information of the power tires. For example, the method may determine the first preset threshold by comparing the difference code of the electronic control unit corresponding to the vehicle type of the vehicle to be detected, the operating system setting parameter, and/or the communication mode between the electronic control unit and the vehicle to be detected, and may obtain the first mileage information, the second mileage information, and the vehicle information associated with the check result through an On Board Diagnostics (OBD) interface of the vehicle to be detected.

In the method, if the check result indicates that the matching degree between the vehicle to be detected and the electronic control unit meets the first preset threshold, it can be indicated that the operating system of the electronic control unit is not tampered, and correspondingly, the driving data stored in the electronic control unit is the driving data of the vehicle to be detected, and the matching degree between the second mileage information recorded by the electronic control unit and the actual total driving mileage of the vehicle to be detected is higher. Therefore, compared with the prior art, the first detection result is determined based on the first mileage information recorded on the instrument panel of the vehicle to be detected and the second mileage information recorded in the electronic control unit, so that the deviation between the total mileage displayed on the instrument panel of the vehicle to be detected and the actual total mileage can be identified, and the accuracy of detecting whether the total mileage of the vehicle is tampered or not is improved.

In a possible implementation manner of the first aspect, before the determining a first detection result of the vehicle to be detected according to the first mileage information and the second mileage information, the method further includes: obtaining modification information of the vehicle to be detected, wherein the modification information is used for describing the change of a power system of the vehicle to be detected; the determining a first detection result of the vehicle to be detected according to the first mileage information and the second mileage information includes: and determining the first detection result of the vehicle to be detected according to the first mileage information, the second mileage information and the refitting information.

In this embodiment, the refitting information may be obtained, for example, through a third-party network device storing the vehicle refitting report information to be detected. The powertrain variations described above may include modifying the mechanical structure of the vehicle power device/kit to be tested, and may also include modifying the software design of the force control module. In order to maintain the power performance of the vehicle, the mechanical structure of the vehicle power device/kit generally needs to correspond to the software design of the power control module in the same vehicle power system, and modification of the mechanical structure or the software design in the power system may cause great deviation between the driving data recorded by the electronic control unit of the vehicle and the actual driving data.

In one possible implementation manner of the first aspect, the determining the first detection result of the vehicle to be detected according to the first mileage information, the second mileage information, and the refitting information includes: and if the refitting information indicates that the circumference of the power tire of the vehicle to be detected is larger than a second preset threshold value, and the mileage value corresponding to the first mileage information is smaller than or equal to the mileage value corresponding to the second mileage information, determining that the first detection result of the vehicle to be detected is that the total driving mileage of the vehicle to be detected is tampered, wherein the second preset threshold value is matched with the tire specification parameters stored by the electronic control unit.

In the present embodiment, the tire specification parameters include, but are not limited to, the diameter, radius, or circumference of the power tire. It can be understood that the electronic control unit may calculate the second mileage information according to the stored tire specification parameters and the rotational speed information corresponding to the power tire, if the circumference of the modified power tire is increased, the mileage value corresponding to the second mileage information calculated by the electronic control unit may be smaller than the actual driving mileage value, at this time, if the mileage value corresponding to the first mileage information displayed on the dashboard is smaller than the mileage value corresponding to the second mileage information, it may be indicated that the total mileage value displayed on the dashboard is also tampered except that the total mileage is tampered due to modifying the power tire, if the mileage value corresponding to the first mileage information displayed on the dashboard is equal to the mileage value corresponding to the second mileage information, it may be indicated that the total mileage is tampered due to modifying the power tire of the vehicle to be detected, and the accuracy of detecting whether the total driving mileage of the vehicle is tampered.

In a possible implementation manner of the first aspect, the determining the first detection result of the vehicle to be detected according to the first mileage information, the second mileage information, and the refitting information includes: and if the refitting information indicates that a mileage calculation program stored in the electronic control unit is changed and the mileage value corresponding to the first mileage information is less than or equal to the mileage value corresponding to the second mileage information, determining that the first detection result of the vehicle to be detected is that the total mileage of the vehicle to be detected is tampered.

In the present embodiment, the mileage calculation process is changed, including but not limited to modifying the configuration parameters and/or calculation logic related to mileage calculation. It can be understood that, under the condition that the electronic control unit is matched with the vehicle to be detected, the terminal device may be accessed through a designated interface configured on the vehicle itself, and the program code stored in the electronic control unit is rewritten through the terminal device to change the mileage calculation program of the vehicle, so that the mileage value corresponding to the second mileage information recorded by the vehicle electronic control unit is greatly deviated from the actual traveled mileage value.

In this embodiment, the TCU is also called a transmission computer, and the total driving mileage of the vehicle to be detected can be calculated according to the driving speed of the vehicle. In the method, if the check result indicates that the matching degree between the vehicle to be detected and the electronic control unit does not meet the first preset threshold, it may indicate that the operating system of the electronic control unit is tampered, and correspondingly, the driving data stored in the electronic control unit is the driving data of the vehicle to be detected, and further, the matching degree between the second mileage information recorded by the electronic control unit and the actual total driving mileage of the vehicle to be detected is low, and at this time, the mileage data recorded in the electronic control unit is used as the detection basis to possibly cause misjudgment.

Similarly, in the method, if the check result indicates that the matching degree between the vehicle to be detected and the electronic control unit does not meet the first preset threshold, it may indicate that the operating system of the electronic control unit is tampered, and correspondingly, the driving data stored in the electronic control unit is the driving data of the vehicle to be detected, and further, the matching degree between the second mileage information recorded by the electronic control unit and the actual total driving mileage of the vehicle to be detected is low, and at this time, the mileage data recorded in the electronic control unit is used as the detection basis, which may cause misjudgment.

In this embodiment, the service record is stored in the target server. The identification information may uniquely identify the vehicle to be detected, which includes, but is not limited to, a Vehicle Identification Number (VIN). For example, in the target server, the maintenance record may be stored according to a storage rule corresponding to the identification information, and correspondingly, the identification information is used as an index, so that the maintenance record corresponding to the vehicle to be detected can be quickly and accurately obtained from the target server.

The mileage detection method provided by the application relates to the technical field of automobiles, and can be particularly applied to detecting whether the total mileage of a vehicle is tampered in a second-hand vehicle transaction process.

At present, the general way of detecting the total mileage of a used vehicle is to estimate the mileage of the vehicle by a professional according to the personal experience and the degree of wear of the vehicle, compare the mileage with the mileage displayed on a dashboard of the vehicle, and finally determine whether the total mileage of the vehicle is tampered according to the comparison result. However, the method is easily affected by human factors, and may cause a large deviation between the estimated mileage and the actual mileage of the vehicle, which may result in that whether the total mileage of the vehicle is tampered with or not cannot be accurately detected.

In view of the above problems, the embodiments of the present application provide a mileage detection method, which can improve the accuracy of detecting whether the total mileage of a vehicle is tampered.

Referring to fig. 1, the mileage detection method will be described with reference to fig. 1 in an embodiment of the present application, and fig. 1 is a schematic flow chart of a first mileage detection method provided in the embodiment of the present application.

As shown in fig. 1, the mileage detection method includes the following steps:

s101, the vehicle diagnosis equipment/server obtains first mileage information recorded by a vehicle to be detected through an instrument panel.

And communication connection is established between the vehicle diagnosis equipment or the server and the vehicle to be detected, and the first mileage information comprises total mileage information displayed on an instrument panel of the vehicle to be detected. For example, when the vehicle diagnostic device obtains the first mileage information, the first mileage information recorded by the instrument panel (or odometer) is read through the OBD interface of the vehicle to be detected, and when the server obtains the first mileage information, the server may receive the first mileage information reported by the vehicle to be detected through a communication connection with the vehicle to be detected.

S102, the vehicle diagnosis equipment/server obtains a verification result of the electronic control unit of the vehicle to be detected, and the verification result is used for describing the matching degree of the vehicle to be detected and the electronic control unit.

The electronic control unit is in communication connection with a vehicle to be detected, and may calculate a total driving range of the vehicle to be detected according to rotational speed information of a power tire, and the electronic control unit may be determined according to a type of a power system of the vehicle to be detected, for example, if the vehicle to be detected is a conventional fuel vehicle, the electronic control unit may be an Electronic Control Unit (ECU), if the vehicle to be detected is a new energy vehicle, the electronic control unit may be a Vehicle Control Unit (VCU), and if the vehicle to be detected is a hybrid vehicle, the electronic control unit may also be a hybrid vehicle control unit (HCU).

For example, the vehicle diagnosis device or the server may check a difference code of a loaded electronic control unit of the vehicle to be detected, an operating system setting parameter, and/or a communication method with the vehicle to be detected, to obtain the check result, so as to determine a matching degree between the vehicle to be detected and the electronic control unit. The difference code may be a vehicle VIN adapted to the electronic control unit, or a version number of the electronic control unit (in the case of different version numbers, the electronic control unit has different corresponding mounting interface positions on the vehicle, and may also have different corresponding sensor configurations in the vehicle, and if the version number of the electronic control unit mounted on the vehicle to be detected is different from that of the vehicle-mounted electronic control unit originally mounted on the vehicle, a specified fault code may be generated after the vehicle to be detected and the electronic control unit are powered on). The operating system setting parameters correspond to control functions supported by the vehicle to be detected, and if the operating system setting parameters corresponding to the electronic control unit loaded on the vehicle to be detected are different from the operating system setting parameters corresponding to the vehicle-mounted electronic control unit originally loaded on the vehicle, great differences can be presented in the control functions or performances of the vehicle. For example, when the original electronic control unit corresponding to the vehicle with higher information security communicates with the vehicle, a specified encryption mode is adopted to prevent other devices from tampering data transmitted in the vehicle communication system.

Optionally, the diagnostic device or the server may determine the matching degree by obtaining the vehicle VIN of the vehicle to be detected, and comparing the vehicle VIN with the vehicle VIN adapted to the currently loaded electronic control unit to determine the similarity between the vehicle VIN and the vehicle VIN. Or, by searching a map containing the model of the vehicle to be detected and the model of the electronic control unit, comparing differences (including differences of operating system setting parameters and/or differences of communication modes between the electronic control unit currently loaded in the vehicle to be detected and the corresponding electronic control unit in the map) to determine the matching degree.

S103, the verification result indicates that the matching degree meets a first preset threshold value.

For example, the method may determine the first preset threshold by comparing a difference code of an electronic control unit corresponding to the type of the vehicle to be detected, an operating system setting parameter, and/or a communication mode with the vehicle to be detected. It can be understood that, taking the case of determining the first preset threshold value by comparing the vehicle VIN as an example, if the verification result indicates that the similarity between the vehicle VIN of the vehicle to be detected and the vehicle VIN adapted to the currently loaded electronic control unit is greater than or equal to the first preset threshold value, it may indicate that the matching degree satisfies the first preset threshold value.

For example, if the check result indicates that the matching degree between the vehicle to be detected and the electronic control unit meets the first preset threshold, it may be indicated that the operating system of the electronic control unit is not tampered, and correspondingly, the reliability that the driving data stored in the electronic control unit is the driving data of the vehicle to be detected is higher, and further, the matching degree between the second mileage information recorded by the electronic control unit and the actual total mileage of the vehicle to be detected is higher.

And S104, the vehicle diagnosis equipment/server acquires second mileage information recorded by the vehicle to be detected through the electronic control unit.

For example, the vehicle diagnosis device may read data in the electronic control unit through an OBD interface of the vehicle to be detected, and generate corresponding diagnosis information, and extract the second mileage information from the diagnosis information if no abnormality occurs in the diagnosis information. Or, the server may receive the second mileage information reported by the vehicle to be detected through a communication connection between the server and the vehicle to be detected.

Optionally, the condition that the diagnostic information is not abnormal includes that the diagnostic information does not have an information missing behavior and/or that the mileage value corresponding to the diagnostic information meets a preset distribution rule (the simulation map corresponding to the mileage value does not have an abnormal discrete point), for example, the information missing behavior includes, but is not limited to, that the mileage information is empty or cleared in a specified time period, and the preset distribution rule may be obtained by calculating a distribution function that a total mileage value obtained in multiple time periods meets.

And S105, determining a first detection result of the vehicle to be detected according to the first mileage information and the second mileage information.

The first detection result is used for determining whether the total driving mileage of the vehicle to be detected is tampered, and the information recorded in the first detection result may be used for describing a mileage difference value, a ratio value and/or other data forms capable of reflecting differences between the first mileage information and the second mileage information. For example, if the difference between the two detected results exceeds the allowable error range, it may be determined that the total mileage of the vehicle to be detected is tampered, otherwise, it may be determined that no tampering has occurred. The allowable error range can be obtained by testing an experimental vehicle belonging to the same vehicle type as the vehicle to be detected.

In the embodiment of the application, compared with the prior art, the first detection result is determined based on the first mileage information recorded on the instrument panel of the vehicle to be detected and the second mileage information recorded in the electronic control unit, so that the deviation between the total mileage displayed on the instrument panel of the vehicle to be detected and the actual total mileage can be identified, and the accuracy of detecting whether the total mileage of the vehicle is tampered or not is improved.

In view of the fact that besides the manual modification of the mileage data displayed in the instrument panel (or odometer) of the vehicle, the modification of the vehicle power system for improving the vehicle dynamic performance also usually results in the total mileage of the vehicle being tampered, based on this, the embodiment of the present application also provides a flow diagram of a second mileage detection method, please refer to fig. 2.

As shown in fig. 2, the mileage detection method includes the following steps:

s201, the vehicle diagnosis equipment/server obtains first mileage information recorded by a vehicle to be detected through an instrument panel.

S202, the vehicle diagnosis equipment/server obtains a verification result of the electronic control unit of the vehicle to be detected, and the verification result is used for describing the matching degree of the vehicle to be detected and the electronic control unit.

S203, the check result indicates that the matching degree meets a first preset threshold value.

And S204, the vehicle diagnosis equipment/server acquires second mileage information recorded by the vehicle to be detected through the electronic control unit.

For the specific implementation of steps S201 to S204, reference may be made to the related descriptions of steps S101 to S104 in the foregoing embodiments, which are not repeated herein.

S205, the vehicle diagnosis equipment/server obtains the refitting information of the vehicle to be detected.

The modification information is used for describing a change of a power system of the vehicle to be detected, optionally, the modification information may be obtained through a third-party network device storing modification provision information of the vehicle to be detected, and for example, the vehicle diagnosis device or the server may obtain the vehicle modification provision information corresponding to the vehicle to be detected by using the driving license or VIN of the vehicle to be detected as an inquiry index under the condition that the access authority of the third-party network device is obtained, and extract the modification information from the driving license or VIN. The powertrain variations described above may include modification of the mechanical structure of the vehicle powertrain/package under test, and may also include modification of the software design of the force control module.

S206, the vehicle diagnosis device/server determines a first detection result of the vehicle to be detected according to the first mileage information, the second mileage information and the modification information.

The first detection result is used for determining whether the total mileage of the vehicle to be detected is tampered, and information in the first detection result may be recorded in a mileage difference value, a mileage ratio value and/or other data forms capable of reflecting differences between the first mileage information and the second mileage information under the condition that the modification information is integrated. For example, in the case of integrating the modified information, if the difference between the first mileage information and the second mileage information, which is shown in the first detection result, exceeds an allowable error range, it may be determined that the total mileage of the vehicle to be detected is tampered, and otherwise, it may be determined that the total mileage of the vehicle to be detected is not tampered. The allowable error range can be obtained by testing an experimental vehicle belonging to the same vehicle type as the vehicle to be detected, and it should be noted that the allowable error range may be the same as or different from the error range described in step S105 in the foregoing embodiment, and is not limited herein.

In this embodiment, since in the power system of the same vehicle, in order to maintain the power performance of the vehicle, the mechanical structure of the vehicle power device/kit generally needs to correspond to the software design of the power control module, and the modification of the mechanical structure or the software design in the power system may cause a large deviation between the driving data recorded by the electronic control unit of the vehicle and the actual driving data.

In an alternative embodiment, the step S206 may include:

s2061, if the modification information indicates that the circumference of the power tire of the vehicle to be detected is greater than a second preset threshold, and the mileage value corresponding to the first mileage information is less than or equal to the mileage value corresponding to the second mileage information, determining that the first detection result of the vehicle to be detected is that the total mileage of the vehicle to be detected is tampered with, and the second preset threshold is matched with the tire specification parameters stored in the electronic control unit.

The tire specification parameters include, but are not limited to, the diameter, radius or circumference of the power tire. It can be understood that the electronic control unit may obtain the second mileage information by acquiring the rotation speed information acquired by the sensor corresponding to the power tire and calculating the second mileage information by combining the stored tire specification parameters. It can be understood that, if the circumference of the modified power tire is increased, the mileage value corresponding to the second mileage information calculated by the electronic control unit is smaller than the actual driving mileage value, at this time, if the mileage value corresponding to the first mileage information displayed on the dashboard is smaller than the mileage value corresponding to the second mileage information, it may be indicated that the total mileage value displayed on the dashboard is also tampered except for the total mileage caused by modifying the power tire, and if the mileage value corresponding to the first mileage information displayed on the dashboard is equal to the mileage value corresponding to the second mileage information, it may be indicated that the total mileage of the vehicle to be detected is tampered caused by modifying the power tire, and the accuracy of detecting whether the total driving mileage of the vehicle is tampered may be further improved.

In an optional implementation manner, the step S206 may further include:

s2062, if the modified information indicates that the mileage calculation program stored in the electronic control unit changes and the mileage value corresponding to the first mileage information is less than or equal to the mileage value corresponding to the second mileage information, determining that the first detection result of the vehicle to be detected is that the total mileage of the vehicle to be detected is tampered with.

Illustratively, the mileage calculation process may be modified, including, but not limited to, modifying configuration parameters and/or calculation logic associated with mileage calculation. Optionally, the vehicle diagnosis device or the server may obtain information about a change of the mileage calculation program based on the modification information stored in the third-party network device, or may determine whether the mileage calculation program stored in the electronic control unit of the vehicle to be detected changes currently by obtaining total mileage values recorded by the electronic control unit at a plurality of different time points and comparing differences between the total mileage values corresponding to each time point.

It can be understood that, under the condition that the electronic control unit is matched with the vehicle to be detected, the terminal device may be accessed through a designated interface configured in the vehicle itself, and the program code stored in the electronic control unit is rewritten through the terminal device, so as to change the mileage calculation program of the vehicle, so that the mileage value corresponding to the second mileage information recorded by the vehicle electronic control unit has a larger deviation from the actual mileage value.

It should be noted that, in an alternative embodiment, before or after the step S2061 is executed, the step S2062 may also be executed to implement simultaneous detection of the influence of the refitting of the power tire and the refitting of the mileage calculating program stored in the electronic control unit on the total mileage traveled, so as to further improve the accuracy of detecting whether the total mileage traveled by the vehicle is tampered.

In order to further improve the accuracy of detecting whether the total mileage of the vehicle is tampered, in the case that the vehicle to be detected is an automatic transmission type, the mileage information recorded by the TCU of the vehicle to be detected can be combined to perform judgment, and based on this, the embodiment of the present application provides a flowchart of a third mileage detection method, please refer to fig. 3.

As shown in fig. 3, the mileage detection method includes the following steps:

s301, the vehicle diagnosis device/server obtains first mileage information recorded by the vehicle to be detected through the instrument panel.

S302, the vehicle diagnosis equipment/server obtains a verification result of the electronic control unit of the vehicle to be detected, and the verification result is used for describing the matching degree of the vehicle to be detected and the electronic control unit.

For the specific implementation of steps S301 to S302, reference may be made to the related descriptions of steps S101 to S102 in the foregoing embodiments, which are not repeated herein.

And S303, the checking result indicates that the matching degree does not meet a first preset threshold value.

For example, if the check result indicates that the matching degree between the vehicle to be detected and the electronic control unit does not satisfy the first preset threshold, it may indicate that the operating system of the electronic control unit is tampered, and correspondingly, the driving data stored in the electronic control unit is the driving data of the vehicle to be detected, and the reliability is low, further, the matching degree between the second mileage information recorded by the electronic control unit and the actual total mileage of the vehicle to be detected is low, and at this time, the mileage data recorded in the electronic control unit is used as the detection basis, which may cause an erroneous determination.

S304, the vehicle diagnosis device/server obtains third mileage information recorded by the vehicle to be detected through the TCU.

For example, the TCU of the vehicle to be detected may implement automatic transmission control of the vehicle to be detected, and may establish communication connection with the vehicle to be detected through a Controller Area Network (CAN) bus, and may calculate the total driving mileage of the vehicle to be detected according to the driving speed of the vehicle. Optionally, the vehicle diagnostic device may read data in the TCU through the OBD interface, generate corresponding diagnostic information, and extract the third mileage information from the diagnostic information when no abnormality occurs in the diagnostic information. Or, the server may receive the third mileage information reported by the vehicle to be detected through a communication connection between the server and the vehicle to be detected. For a specific implementation manner of determining whether the diagnosis information is abnormal, reference may be made to the related description of step S104 in the foregoing embodiment, which is not described herein again.

And S305, the vehicle diagnosis device/server determines a second detection result of the vehicle to be detected according to the first mileage information and the third mileage information.

The second detection result is used to determine whether the total driving mileage of the vehicle to be detected is tampered, and the information recorded in the second detection result may be used to describe a mileage difference value, a ratio value and/or other data forms capable of reflecting differences between the first mileage information and the third mileage information.

It should be noted that, after step S305 is executed, the vehicle diagnostic device or the server may directly determine whether the total mileage of the vehicle to be detected is tampered with according to the second detection result, for example, if the difference between the first mileage information and the second mileage information, which is present in the second detection result, exceeds an allowable error range, it may be determined that the total mileage of the vehicle to be detected is tampered with, otherwise, it may be determined that no tampering has occurred. The allowable error range can be obtained by testing an experimental vehicle belonging to the same vehicle type as the vehicle to be detected. After the step S305 is performed, the vehicle diagnostic apparatus or the server may also perform the step S306 to reduce the determination error.

And S306, the vehicle diagnosis equipment/server acquires fourth mileage information recorded in the maintenance record of the vehicle to be detected.

It is understood that, in the case that the vehicle to be detected is within the warranty period, the total mileage of the vehicle actually running at each repair or maintenance time is usually recorded in the maintenance record, and the maintenance record may be stored in a designated network device, and the maintenance record may be obtained through a communication interface opened by the network device, and the fourth mileage information may be extracted from the maintenance record. In an optional implementation manner, the service record is stored in a target server, and before performing step S306, the method may further include:

s3061, the vehicle diagnosis device/server obtains identification information of the vehicle to be detected, where the identification information is used to identify the vehicle to be detected.

The identification information may uniquely identify the vehicle to be detected, which includes but is not limited to a driving license and/or a VIN. For example, the vehicle diagnosis device or the server may obtain the identification information according to a code scanned by a user or vehicle information of the vehicle to be detected manually input.

S3062, if the target server permits, the vehicle diagnosis device/server obtains the maintenance record from the target server based on the identification information.

For example, the target server may store the maintenance record according to a storage rule corresponding to the identification information, and the vehicle diagnosis device or the server may send an inquiry request of the vehicle to be detected to the target server, where the inquiry request includes the identification information, and receive the maintenance record sent by the target server if the target server permits the inquiry request. In this embodiment, the identification information is used as an index, so that the maintenance record corresponding to the vehicle to be detected can be quickly and accurately obtained from the target server.

And S307, determining a third detection result of the vehicle to be detected according to the first mileage information and the fourth mileage information.

The third detection result is used to determine whether the total driving mileage of the vehicle to be detected is tampered, and the information recorded in the third detection result may be used to describe a mileage difference value, a ratio value and/or other data forms capable of reflecting differences between the first mileage information and the fourth mileage information.

It should be noted that, according to the actual scene requirement, the second detection result may be determined first or the third detection result may be determined first, and therefore, the order of determining the second detection result and determining the third detection result is not limited herein. Or, only the second detection result or the third detection result is determined, and whether the total driving range of the vehicle to be detected is tampered with is directly determined according to the second detection result or the third detection result, which can be understood that, in this case, the step S308 does not need to be executed.

In addition, when it is determined whether the total driving range of the vehicle to be detected is tampered according to the third detection result, the determination may also be performed based on a corresponding error range, and the obtaining manner corresponding to the error range may refer to the related description of step S305, which is not described herein again.

And S308, determining whether the total driving mileage of the vehicle to be detected is falsified or not according to the second detection result and the third detection result.

For example, if both the second detection result and the third detection result indicate that the total traveled mileage of the vehicle to be detected is not tampered, it may be determined that the total traveled mileage of the vehicle to be detected is not tampered. Optionally, the vehicle diagnosis device or the server may synchronize a result of determining whether the total mileage has been tampered with to a terminal device of a user.

In this embodiment, the second detection result is determined according to the first mileage information recorded on the instrument panel of the vehicle to be detected and the third mileage information acquired from the TCU of the vehicle to be detected, so that the deviation between the total mileage displayed on the instrument panel of the vehicle to be detected and the actual total mileage recorded in the TCU can be identified, the third detection result is determined according to the first mileage information recorded on the instrument panel of the vehicle to be detected and the fourth mileage information extracted from the maintenance record of the vehicle to be detected, the deviation between the total mileage displayed on the instrument panel of the vehicle to be detected and the actual total mileage recorded in the maintenance record can be identified, and the accuracy of detecting whether the total mileage of the vehicle is tampered can be improved by performing judgment according to the second detection result and the third detection result.

In order to further improve the accuracy of judging whether the total mileage of the vehicle is tampered, under the condition that the vehicle to be detected is of an automatic transmission type and the operating system of the electronic control unit of the vehicle to be detected is not tampered, the first mileage information recorded by the instrument panel of the vehicle to be detected can be compared with the second mileage information recorded by the electronic control unit, the third mileage information recorded by the TCU and the fourth mileage information recorded in the maintenance record respectively to realize joint judgment, based on which, the embodiment of the application provides a flow schematic diagram of a fourth mileage detection method, please refer to fig. 4.

As shown in fig. 4, the mileage detection method includes the following steps:

s401, the vehicle diagnosis device/server obtains first mileage information recorded by a vehicle to be detected through an instrument panel.

S402, the vehicle diagnosis equipment/server obtains a verification result of the electronic control unit of the vehicle to be detected, and the verification result is used for describing the matching degree of the vehicle to be detected and the electronic control unit.

And S403, the verification result indicates that the matching degree meets a first preset threshold.

S404, the vehicle diagnosis device/server obtains second mileage information recorded by the vehicle to be detected through the electronic control unit.

Optionally, step S404 may be replaced by: the vehicle diagnosis device/server obtains second mileage information from a third-party computing platform, wherein the third-party computing platform corresponds to the vehicle to be detected, and can realize the automatic driving function of the vehicle to be detected according to the running condition of the vehicle to be detected.

In an optional implementation manner, before performing step S405, the method further includes:

s4051, the vehicle diagnosis device/server obtains the refitting information of the vehicle to be detected.

Correspondingly, the step S405 includes:

s4052, the vehicle diagnosis device/server determines a first detection result of the vehicle to be detected according to the first mileage information, the second mileage information and the refitting information.

And S410, determining whether the total driving mileage of the vehicle to be detected is falsified according to the first detection result, the second detection result and the third detection result.

The first detection result, the second detection result, and the third detection result may be used to determine whether the total driving mileage of the vehicle to be detected is tampered, and for example, if the second detection result and the third detection result both indicate that the total driving mileage of the vehicle to be detected is not tampered, it may be determined that the total driving mileage of the vehicle to be detected is not tampered.

In this embodiment, by comparing the first mileage information recorded by the instrument panel of the vehicle to be detected with the second mileage information recorded by the electronic control unit, the third mileage information recorded by the TCU, and the fourth mileage information recorded in the maintenance record, the accuracy of detecting whether the total driving mileage of the vehicle is tampered can be improved, thereby facilitating the realization of guaranteeing the fairness of transactions during the transaction of the vehicle to be detected and guaranteeing the benefits of consumers.

Optionally, in an optional implementation manner, if the mileage data recorded in the dashboard is lost due to damage or replacement of the dashboard of the vehicle to be detected, the vehicle diagnostic device and the server may further obtain the first mileage information from a backup device of the dashboard, the backup device may backup the mileage data recorded in the dashboard when the dashboard is powered off, and the mileage data backed up in the backup device may be updated to the dashboard when the dashboard is powered on, so as to reduce loss of the first mileage information caused by maintenance and update of the dashboard.
