Technical Field

[0001] The present disclosure relates to the technical field of automobiles, and particularly to a vehicle mileage backup method, system, device and medium. Background Art

[0002] With the development and wide popularization of household automobiles, the quality of after-sales maintenance of vehicles has gradually attracted attention; when the instrument is replaced during routine vehicle maintenance, the instrument does not record the previous driving mileage of the vehicle, and the new instrument only records from 0 kilometers, thus failing to guarantee some after-sales maintenance rights and interests of customers. When customers improperly change the displayed mileage of the instrument, it is also not conducive to market supervision.

[0003] In summary, the prior art lacks mileage backup technology, which is not conducive to market supervision and cannot guarantee the after-sales maintenance rights and interests of customers. Summary of the Invention

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0041] As Figure 1 shown, a vehicle mileage backup method includes:

[0042] S101. After the vehicle is powered on, controller A for displaying the mileage sends the current mileage data to controller B for mileage backup recording, and receives the mileage backup record data and controller anti-theft information sent by controller B.

[0043] S102. If the current mileage data is greater than or equal to the mileage backup record data, controller A sends mileage valid information to controller B.

[0044] S103. If the current mileage data is less than the mileage backup record data, controller A compares the received controller anti-theft information with the controller anti-theft information stored in controller A; when the controller anti-theft information comparison is consistent, controller A updates the current mileage data to the mileage backup record data.

[0045] Specifically, the implementation is as follows:

[0046] Controller A and controller B are preset with the same controller anti-theft information. When controller A is replaced, the same controller anti-theft information preset in controller B is written into controller A through a diagnostic instrument.

[0047] If the current mileage data is less than the mileage backup record data, controller A compares the received controller anti-theft information with the controller anti-theft information stored in controller A. When the controller anti-theft information comparison is inconsistent, controller A gives an audible and visual alarm.

[0048] When the vehicle is in the powered-on state, controller A periodically sends the current mileage data to controller B and periodically receives the mileage backup record data sent by controller B.

[0049] As Figure 2 shown, controller A outputs the total mileage A_TotalOdometer_Km (maximum value is 999999 KM) to controller B;

[0050] Controller B sends B_TotalOdometer_Km to controller A as the mileage backup output;

[0051] Send the signal A_TotalOdometer_Km_OBDValidData to inform Controller B whether the current A_TotalOdometer_Km is valid. After Controller A powers on each time and compares and passes the controller anti-theft information (only compare once, and will not compare again after the process ends, not elaborated later), and when the current B_TotalOdometer_Km ≤ A_TotalOdometer_Km, Controller A sets A_TotalOdometer_Km_OBDValidData to valid ("0x0:Valid"), otherwise, A_TotalOdometer_Km_OBDValidData is always set to invalid ("0x1:Not_Valid");

[0052] When the vehicle powers on to ON, Controller B needs to send out the controller anti-theft information of Controller B (the vehicle controller anti-theft information stored in Controller B itself). If the received A_TotalOdometer_Km_OBDValidData = "0X0", Controller B will perform mileage backup storage;

[0053] When the vehicle powers on to ON and a new Controller A is replaced, after the diagnostic instrument writes the controller anti-theft information to Controller A, Controller A must read and compare the backup information received from B. If the comparison with the controller anti-theft information of Controller B passes and B_TotalOdometer_Km > A_TotalOdometer_Km, Controller A must update and store the display mileage according to the backup mileage;

[0054] A vehicle mileage backup storage method adopts the above-mentioned vehicle mileage backup method,

[0055] After the vehicle powers on, Controller B sends the mileage backup record data and controller anti-theft information stored in itself to Controller A;

[0056] When Controller B receives the mileage valid information sent by Controller A, Controller B updates the mileage backup record data to the current mileage data sent by Controller A.

[0057] The initial mileage backup record data of Controller B is set to a preset value.

[0058] As Figure 3 shown, a vehicle mileage backup system includes: Controller A and Controller B;

[0059] Controller A is used to display the mileage;

[0060] Controller B is used for mileage backup record;

[0061] After the vehicle is powered on, controller A sends the current mileage data to controller B and receives the mileage backup record data and the controller anti-theft information sent by controller B;

[0062] If the current mileage data is greater than or equal to the mileage backup record data, controller A sends mileage valid information to controller B;

[0063] If the current mileage data is less than the mileage backup record data, controller A compares the received controller anti-theft information with the controller anti-theft information stored in controller A; when the controller anti-theft information comparison is consistent, controller A updates the current mileage data to the mileage backup record data.

[0064] As Figure 4 shown, the present disclosure provides an electronic device, including a processor 401, a communication interface 402, a memory 403, and a communication bus 404. Among them, the processor 401, the communication interface 402, and the memory 403 complete mutual communication through the communication bus 404;

[0065] The memory 403 stores a computer program;

[0066] The processor 401, when executing the computer program stored on the memory 403, implements the above-mentioned vehicle mileage backup method or implements the above-mentioned vehicle mileage backup storage method.

[0067] In a fifth aspect, a computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, it implements the above-mentioned vehicle mileage backup method or implements the above-mentioned vehicle mileage backup storage method.

[0068] The computer-readable storage medium may be included in the device / device described in the above embodiments; it may also exist separately and not be assembled into the device / device. The above computer-readable storage medium carries one or more programs, and when the above one or more programs are executed, the method according to the embodiments of the present disclosure is implemented.

[0069] According to the embodiments of the present disclosure, the computer-readable storage medium may be a non-volatile computer-readable storage medium, for example, it may include but is not limited to: portable computer disks, hard disks, random access memories (RAMs), read-only memories (ROMs), erasable programmable read-only memories (EPROMs or flash memories), portable compact disk read-only memories (CD-ROMs), optical storage devices, magnetic storage devices, or any suitable combination of the above. In the present disclosure, the computer-readable storage medium may be any tangible medium that contains or stores a program, and the program can be used by or combined with an instruction execution system, device, or device.

[0070] To enable those skilled in the art to better understand the present disclosure, the principles of the present disclosure are described below in conjunction with the accompanying drawings:

[0071] As Figure 5 shown, for controller A,

[0072] The A_TotalOdometer_Km_OBDValidData sent by controller A defaults to "0x1:Not_Valid";

[0073] Each time KL15 is powered on, the ICM determines whether the operation of writing the controller anti-theft information has been performed through the 2E service before restart;

[0074] When the vehicle instrument has not performed the operation of writing the controller anti-theft information, compare whether the controller anti-theft information of the current controller A is the same as that of controller B:

[0075] If it is inconsistent with its own controller anti-theft information, prompt "The controller anti-theft information is incorrect!", which is constantly displayed in classical Chinese and cannot be exited for 5s, and A_TotalOdometer_Km_OBDValidData continuously sends "0x1:Not_Valid";

[0076] If they are consistent, then judge the magnitudes of A_TotalOdometer_Km and B_TotalOdometer_Km:

[0077] If B_TotalOdometer_Km > A_TotalOdometer_Km, then A_TotalOdometer_Km_OBDValidData continuously sends "0x1:Not_Valid";

[0078] If B_TotalOdometer_Km ≤ A_TotalOdometer_Km, then A_TotalOdometer_Km_OBDValidData continuously sends "0x0:Valid";

[0079] When the vehicle instrument has performed the operation of writing the controller anti-theft information, compare whether the controller anti-theft information of the current controller A is the same as that of controller B:

[0080] If it is inconsistent with its own controller anti-theft information, prompt "The controller anti-theft information is incorrect!", which is constantly displayed in classical Chinese and cannot be exited for 5s. And A_TotalOdometer_Km_OBDValidData continuously sends "0x1:Not_Valid";

[0081] If they are consistent, then compare the magnitudes of A_TotalOdometer_Km and B_TotalOdometer_Km;

[0082] If B_TotalOdometer_Km > A_TotalOdometer_Km, the instrument must immediately update the displayed mileage according to the backup value B_TotalOdometer_Km and store it. After the update is completed,

[0083] Change A_TotalOdometer_Km_OBDValidData to send "0x0:Valid", and the mileage restoration function ends;

[0084] If B_TotalOdometer_Km ≤ A_TotalOdometer_Km, then Controller A does not need to update the mileage, and A_TotalOdometer_Km_OBDValidData is also changed to send "0x0:Valid", and the mileage restoration function also ends;

[0085] If an invalid value is received or this signal (B_TotalOdometer_Km) cannot be received, the instrument does not update according to the backup value, and A_TotalOdometer_Km_OBDValidData continuously sends "0x1:Not_Valid"; at the same time, the instrument prompts "The controller anti-theft information is incorrect!" and displays it for 5 s.

[0086] For Controller B,

[0087] Before Controller B performs mileage backup, the default mileage value of Controller B is the initial value: the preset value of 0 km;

[0088] After the vehicle is powered on to the ON state, receive the periodic signals of A_TotalOdometer_Km and A_TotalOdometer_Km_OBDValidData sent by Controller A;

[0089] When A_TotalOdometer_Km_OBDValidData is "0x0:Valid", Controller B performs mileage backup storage according to the original logic, and does not perform mileage backup storage when it is "0x1:Not_Valid";

[0090] After the vehicle is powered on to the ON state, Controller B reads its own backup mileage value and its own controller anti-theft information, and outputs B_TotalOdometer_Km and the controller anti-theft information of Controller B to Controller A;

[0091] Controller B determines whether to perform mileage backup storage according to the original logic;

[0092] Although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
