Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a method, device, equipment and medium for flashing a vehicle electronic control unit. Background Art

[0002] Currently, ODX-OTX (Open Diagnostic data eXchange-Open Test sequence eXchange) is a new technology for vehicle diagnosis. Diagnostic data and diagnostic processes can be obtained by parsing vehicle diagnostic data packets, thereby performing vehicle diagnosis. In existing methods, there are two ways to flash a vehicle. One is to use code to implement flashing according to the protocols and processes provided by OEM (Original Entrusted Manufacture) suppliers. The other is that the manufacturer writes JAR (Java Archive) packages or OTX (-Open Test sequence eXchange) source files, puts them into the vehicle type diagnostic data packets for packaging, and the diagnostic device downloads the vehicle diagnostic data packets through the network, and then uses the vehicle diagnostic data packets for flashing. Among them, flashing with code has a high coupling degree, high after-sales development cost, and is not easy to change. Flashing with JAR packages requires high requirements for developers. However, when using the above two methods for flashing, if a flashing failure occurs, the flashing fails, and the flashing fault tolerance rate is relatively low.

[0044] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0045] Currently, there are two ways to flash a vehicle. One is to use code to implement flashing according to the protocols and processes provided by OEM suppliers. The other is that the manufacturer writes a JAR package or an OTX source file, puts it into the vehicle diagnostic data packet for packaging, and the diagnostic device downloads the vehicle diagnostic data packet through the network, and then uses the vehicle diagnostic data packet for flashing. However, when using the above two methods for flashing, if a flashing failure occurs, the flashing fails and the flashing fault tolerance rate is relatively low.

[0046] To overcome the above problems, this application provides a vehicle electronic control unit flashing solution, which can improve the flashing fault tolerance rate.

[0047] In the vehicle electronic control unit flashing solution of this application, the system framework adopted can be seen Figure 1 as shown. Specifically, it may include a server 01 and a diagnostic device 02, and may also include a development terminal 03. The hardware forms of the diagnostic device 02 and the development terminal 03 include but are not limited to mobile terminals, personal computers (PCs, Personal Computers), and personal digital assistants.

[0048] Among them, the server 01 is specifically used to receive and save the vehicle diagnostic data packet uploaded by the development terminal 03, and send the vehicle diagnostic data packet to the diagnostic device 02. The diagnostic device 02 is specifically used to obtain the vehicle diagnostic data packet and determine whether there is target diagnostic data in the vehicle diagnostic data packet. If there is target diagnostic data, the vehicle electronic control unit is flashed using the target diagnostic file. If the target diagnostic file does not exist, a preset flashing module written in advance through a preset flashing code is called to flash the vehicle electronic control unit. The development terminal 03 is specifically used to determine whether a target diagnostic file is required when flashing the vehicle electronic control unit; if it is determined that the target diagnostic file is required, the target diagnostic file is saved to the vehicle diagnostic data packet corresponding to the vehicle and the vehicle diagnostic data packet is uploaded to the server 01; if it is determined that the target diagnostic file is not required, a preset flashing module written in advance through a preset flashing code is directly saved to the diagnostic device 02.

[0049] See Figure 2 As shown, an embodiment of this application discloses a method for flashing a vehicle electronic control unit, which is applied to a diagnostic device. The method includes:

[0050] Step S11: Obtain the vehicle diagnostic data packet corresponding to the vehicle from the server.

[0051] In the embodiment of the present application, first, the vehicle flashing program needs to be started, then the vehicle identification information corresponding to the vehicle is obtained, the vehicle identification information is uploaded to the server, and based on the vehicle identification information, the vehicle diagnostic data packet corresponding to the vehicle is obtained from the server. It should be noted that after obtaining the vehicle diagnostic data packet, the diagnostic device can save the vehicle diagnostic data packet locally.

[0052] It should be noted that the vehicle identification information includes, but is not limited to, VIN (Vehicle Identification Number).

[0053] Step S12: Query whether there is a target diagnostic file in the vehicle diagnostic data packet.

[0054] In the embodiment of the present application, after obtaining the vehicle diagnostic data packet, the vehicle diagnostic data packet is parsed, and it is determined whether there is a target diagnostic file in the vehicle diagnostic data packet.

[0055] It should be noted that as Figure 3 shown, the target diagnostic file is a flashing JAR package, and the vehicle diagnostic data packet includes, but is not limited to, the target diagnostic file and other vehicle diagnostic data files; as Figure 4 shown, the JAR package is taken out from the vehicle diagnostic data packet.

[0056] Step S13: If there is the target diagnostic file in the vehicle diagnostic data packet, use the target diagnostic file to flash the vehicle electronic control unit.

[0057] In an embodiment of the present application, if the target diagnostic file exists in the vehicle diagnostic data packet, the target diagnostic file is copied to a preset directory, and then the target diagnostic file is called from the preset directory to flash the vehicle electronic control unit. Specifically, the target diagnostic file, the dynamic link library file, the first preset source file constructed based on the target diagnostic process, and the second preset source file constructed based on the target diagnostic data are copied to the preset directory; the first preset source file is selected from the preset directory and parsed to obtain the target diagnostic process, and then the second preset source file is selected from the preset directory and parsed to obtain the target diagnostic data; based on the target diagnostic process and the target diagnostic data, the target diagnostic file and the dynamic link library file are called from the preset directory to flash the vehicle electronic control unit. It should be noted that the first preset source file is an OTX source file, and the second preset source file is an ODX source file; specifically, it should be noted that when flashing using a JAR package, the manufacturer does not need to inform the supplier of the flashing protocol and steps, and the supplier only needs to parse the source file according to the corresponding standard, and then the JAR package will be called in relevant places in the source file, and the entire flashing process is completed by the manufacturer by configuring the source file and the JAR package, which can effectively prevent leakage of secrets. It should be noted that the JAR package is a packaged file developed using JAVA, and JAR is a computer file format; the dynamic link library (DLL, Dynamic Link Library) file includes but is not limited to the security algorithm calculation dynamic link library file, and the security algorithm calculation dynamic link library file is used to calculate the security algorithm in the JAR package. It should be noted that the manufacturer may be a vehicle OEM, and the supplier may be a diagnostic equipment service provider.

[0058] It should be noted that the target diagnostic data includes but is not limited to fault codes and data stream algorithms, and the target diagnostic process is a special function mainly used to perform vehicle diagnosis; for example, matching keys, and the corresponding steps include the first step of prompting the user to power on the vehicle, the second step of sending a target instruction, and the third step of parsing the target diagnostic process.

[0059] Step S14: If the target diagnostic file does not exist in the vehicle diagnostic data packet, a preset flashing module written by a preset flashing code is called to flash the vehicle electronic control unit.

[0060] In an embodiment of the present application, when flashing the vehicle electronic control unit with a preset flashing module written by a preset flashing code, the manufacturer needs to inform all the protocols and steps of the flashing.

[0061] It can be seen that the present application obtains the vehicle diagnostic data packet corresponding to the vehicle from the server; queries whether there is a target diagnostic file in the vehicle diagnostic data packet; if there is the target diagnostic file in the vehicle diagnostic data packet, the vehicle electronic control unit is flashed using the target diagnostic file; if there is no target diagnostic file in the vehicle diagnostic data packet, a preset flashing module pre-written with a preset flashing code is called to flash the vehicle electronic control unit. Thus, the present application is compatible with two methods of flashing the vehicle electronic control unit, namely, using the target diagnostic file to flash the vehicle electronic control unit and calling the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit, providing two different flashing methods for the diagnostic device; because the present application queries whether there is a target diagnostic file in the vehicle diagnostic data packet and selects to use the target diagnostic file or call the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit, providing an execution mode for intelligent judgment of the flashing method, the flashing efficiency and the flashing fault tolerance rate are improved.

[0062] See Figure 5 As shown, an embodiment of the present application discloses a specific method for flashing a vehicle electronic control unit, which is applied to a diagnostic device. The method includes:

[0063] Step S21: Obtain the vehicle diagnostic data packet corresponding to the vehicle from the server.

[0064] Step S22: Query whether there is a target diagnostic file in the vehicle diagnostic data packet.

[0065] Step S23: If there is the target diagnostic file in the vehicle diagnostic data packet, flash the vehicle electronic control unit using the target diagnostic file.

[0066] Step S24: If the flashing of the vehicle electronic control unit using the target diagnostic file fails, call the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit.

[0067] In the embodiment of the present application, if the flashing of the vehicle electronic control unit using the target diagnostic file fails, it is necessary to call the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit. This process provides a method of calling the preset flashing module pre-written with the preset flashing code for flashing in the case of failure of flashing using the target diagnostic file, improving the flashing stability, security and success rate.

[0068] Step S25: If there is no target diagnostic file in the vehicle diagnostic data packet, call the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit.

[0069] In this embodiment, for the specific processes of the above steps S21 to S23 and S25, reference may be made to the corresponding content disclosed in the foregoing embodiments, and details thereof will not be elaborated herein.

[0070] It can be seen that this application obtains the vehicle diagnostic data packet corresponding to the vehicle from the server; queries whether there is a target diagnostic file in the vehicle diagnostic data packet; if there is the target diagnostic file in the vehicle diagnostic data packet, the vehicle electronic control unit is flashed with the target diagnostic file; if the flashing of the vehicle electronic control unit with the target diagnostic file fails, the preset flashing module pre-written with the preset flashing code is called to flash the vehicle electronic control unit; if there is no target diagnostic file in the vehicle diagnostic data packet, the preset flashing module pre-written with the preset flashing code is called to flash the vehicle electronic control unit. Thus, this application is compatible with two methods of flashing the vehicle electronic control unit, namely, flashing with the target diagnostic file and calling the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit, providing two different flashing methods for the diagnostic device; because this application selects to use the target diagnostic file or call the preset flashing module pre-written with the preset flashing code to flash the vehicle electronic control unit by querying whether there is a target diagnostic file in the vehicle diagnostic data packet, providing an execution mode of intelligent judgment of the flashing method, the flashing efficiency and the flashing fault tolerance rate are improved; because this application can also use the preset flashing module written with the preset flashing code to flash after the flashing with the target diagnostic file fails, the flashing stability, security and success rate are improved.

[0071] See Figure 6 As shown, an embodiment of this application discloses a specific method for flashing a vehicle electronic control unit, which is applied to a development terminal. The method includes:

[0072] Step S31: Determine whether a target diagnostic file needs to be used when flashing the vehicle electronic control unit.

[0073] Step S32: If it is determined that the target diagnostic file needs to be used, save the target diagnostic file to the vehicle diagnostic data packet corresponding to the vehicle and upload the vehicle diagnostic data packet to the server.

[0074] In the embodiment of the present application, if it is determined that the target diagnostic file needs to be used, the target diagnostic file needs to be saved to the vehicle diagnostic data packet corresponding to the vehicle, and then the vehicle diagnostic data packet is uploaded to the server. Specifically, after the target diagnostic file is saved to the vehicle diagnostic data packet corresponding to the vehicle, it is necessary to determine the vehicle identification information corresponding to the vehicle, and associate the vehicle identification information with the vehicle diagnostic data packet, and upload the associated vehicle diagnostic data packet to the server, so that the diagnostic device can obtain and save the vehicle diagnostic data packet corresponding to the vehicle from the server based on the vehicle identification information.

[0075] It should be noted that when uploading the vehicle diagnostic data packet to the server, it is also necessary to save the preset flashing module written by the preset flashing code to the diagnostic device, so that when the flashing using the target diagnostic file fails, the preset flashing module written by the preset flashing code can be called for flashing.

[0076] Step S33: If it is determined that the target diagnostic file does not need to be used, directly save the preset flashing module written by the preset flashing code to the diagnostic device.

[0077] In the embodiment of the present application, if it is determined that the target diagnostic file does not need to be used, directly save the preset flashing module written by the preset flashing code to the diagnostic device, so that when the target diagnostic file does not exist in the vehicle diagnostic data packet, the preset flashing module written by the preset flashing code can be directly called for flashing.

[0078] It should be noted that when it is determined that the target diagnostic file does not need to be used, the vehicle diagnostic data packet still needs to be sent to the server, but the target diagnostic file does not exist in the vehicle diagnostic data packet.

[0079] It can be seen that the present application determines whether the target diagnostic file needs to be used when flashing the vehicle electronic control unit; if it is determined that the target diagnostic file needs to be used, the target diagnostic file is saved to the vehicle diagnostic data packet corresponding to the vehicle and the vehicle diagnostic data packet is uploaded to the server; if it is determined that the target diagnostic file does not need to be used, directly save the preset flashing module written by the preset flashing code to the diagnostic device. The present application develops the vehicle diagnostic data packet based on whether the target diagnostic file needs to be used when flashing the vehicle electronic control unit, so that the diagnostic device can intelligently select the flashing method based on whether the target diagnostic file exists in the vehicle diagnostic data packet, improving the flashing fault tolerance rate.

[0080] See Figure 7 As shown, the embodiment of the present application discloses a vehicle electronic control unit flashing device, which is applied to a diagnostic device and includes:

[0085] It can be seen that this application is compatible with two methods of flashing a vehicle electronic control unit, namely, flashing by using a target diagnostic file and calling a preset flashing module pre-written with a preset flashing code to flash the vehicle electronic control unit, providing two different flashing methods for a diagnostic device; because this application selects to use a target diagnostic file or call a preset flashing module pre-written with a preset flashing code to flash the vehicle electronic control unit by querying whether a target diagnostic file exists in the vehicle diagnostic data packet, providing an execution manner for intelligently judging the flashing method, the flashing efficiency and the flashing fault tolerance rate are improved.
