[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] The following description, with reference to the accompanying drawings, illustrates a method and apparatus for remote vehicle upgrades according to embodiments of this application. Addressing the problem mentioned in the background section of related technologies where the upgrade process, communication method, and security access algorithm used by each controller differ, the correctness of the upgrade process during remote vehicle upgrades cannot be guaranteed, leading to a reduction in vehicle intelligence and a lower user experience. This application provides a method for remote vehicle upgrades. In this method, an upgrade file for at least one target controller is downloaded from a preset OTA server. The target data field in the upgrade file is obtained, and it is checked whether the target upgrade process, target diagnostic communication type, and target security access algorithm in the target data field are all within preset upgrade conditions. If all are within the preset upgrade conditions, the vehicle is remotely upgraded using the upgrade file, thereby ensuring the correctness of the upgrade process during remote vehicle upgrades, improving vehicle intelligence, and enhancing the user experience. This solves the problem in related technologies where the differences in the upgrade process, communication method, and security access algorithm used by each controller during remote upgrades prevent the guarantee of the correctness of the upgrade process during remote vehicle upgrades, reducing vehicle intelligence and lowering the user experience.

[0032] Specifically, Figure 1 This is a flowchart illustrating a method for remotely upgrading a vehicle, as provided in an embodiment of this application.

[0033] like Figure 1 As shown, the remote vehicle upgrade method includes the following steps:

[0034] In step S101, at least one upgrade file for a target controller is downloaded from a preset OTA server, and the target data field in the upgrade file is obtained.

[0035] It is understood that, according to the embodiments of this application, an upgrade file of at least one target controller in the following steps can be downloaded from the OTA server, thereby obtaining the target data field in the upgrade file, which effectively improves the executability of vehicle upgrade.

[0036] In one embodiment of this application, the upgrade file is a file in the SORecord data field, wherein the file adopts the S19 file format and the S19 file format adopts SORecord.

[0037] In actual implementation, such as Figure 2 As shown, in this embodiment of the application, the upgrade file is a file with an SORecord data field, and the data format in the upgrade file adopts the S19 file format, and the S19 file format adopts SORecord. The record type of SORecord is "S0", and the address field is set with zero (0x0000), thereby effectively improving the accuracy of the upgrade data.

[0038] In step S102, the target upgrade process, target diagnostic communication type and target security access algorithm in the target data domain are read, and it is checked whether the target upgrade process, target diagnostic communication type and target security access algorithm in the target data domain are all within the preset upgrade conditions.

[0039] It is understood that the embodiments of this application can read the target upgrade process, target diagnostic communication type and target security access algorithm in the target data domain, and detect whether the target upgrade process, target diagnostic communication type and target security access algorithm in the target data domain are all within the preset upgrade conditions in the following steps, effectively avoiding the controller from flashing the wrong upgrade file and improving the reliability of the vehicle.

[0040] In this embodiment of the application, the upgrade process, diagnostic communication type, and security access algorithm in the data domain can be customized, as shown in Table 1. Table 1 is a data domain format definition table, and the specific details of Table 1 are as follows:

[0041] Table 1

[0042]

[0043] For example, in S0050000010103F5(checksum), the upgrade process is EEA1.0, the diagnostic communication type is CAN, and the secure access algorithm is Algorithm 3.

[0044] It should be noted that the preset upgrade conditions are set by those skilled in the art based on the actual situation, and are not specifically limited here.

[0045] In one embodiment of this application, detecting whether the target upgrade process, target diagnostic communication type, and target secure access algorithm in the target data domain are within preset upgrade conditions includes: detecting whether the data information of the target upgrade process in the file of the SORecord data domain meets the process range of the preset upgrade conditions, wherein if the process range is met, the target upgrade process is determined to meet the preset upgrade conditions; detecting whether the target diagnostic communication type in the file of the SORecord data domain meets the diagnostic communication type range of the preset upgrade conditions, wherein if the diagnostic communication type range is met, the target diagnostic communication type is determined to meet the preset upgrade conditions; and detecting whether the target secure access algorithm in the file of the SORecord data domain meets the secure access algorithm range of the preset upgrade conditions, wherein if the secure access algorithm range is met, the target secure access algorithm is determined to meet the preset upgrade conditions.

[0046] For example, the OTA master node in this embodiment can download the upgrade file from the OTA server and read the upgrade process, diagnostic communication type, and security access algorithm from the S0 Record data field in the S19 file, as shown in Table 2. Table 2 is the upgrade file identification table, and the specific Table 2 is as follows:

[0047] Table 2

[0048]

[0049]

[0050] For example, embodiments of this application can detect whether the data information of the upgrade process in the SO Record data domain is 0x00 (EEA1.0)-0x02 (EEA3.0). If the process range is met, the upgrade process is determined to meet the upgrade conditions. It can also detect whether the diagnostic communication type in the SO Record data domain is 0x00 (CAN)-0x01 (Eth). If the diagnostic communication type range is met, the diagnostic communication type is determined to meet the upgrade conditions. Finally, it can detect whether the security access algorithm in the SO Record data domain is 0x00 (Algorithm 1)-0x02 (Algorithm 3). If the security access algorithm range is met, the security access algorithm is determined to meet the upgrade conditions.

[0051] In summary, when the upgrade process, diagnostic communication type, and secure access algorithm in the SOrecord data field of the S19 file in this application embodiment all meet the upgrade conditions, remote vehicle upgrade is performed, which effectively improves the reliability of remote vehicle upgrade and enhances vehicle safety.

[0052] Additionally, as shown in Table 2 of the above steps, in one embodiment of this application, both the target diagnostic communication type and the target secure access algorithm include at least one of diagnostic ID, data length, and data stream.

[0053] In one embodiment of this application, detecting whether the target upgrade process, target diagnostic communication type, and target security access algorithm in the target data domain are within the preset upgrade conditions further includes: if the target upgrade process, target diagnostic communication type, and target security access algorithm in the target data domain are not within the preset upgrade conditions, then remote vehicle upgrade is prohibited.

[0054] For example, as shown in Table 2 of the above steps, if the upgrade process, diagnostic communication type, and secure access algorithm in the data domain are not within the upgrade conditions, remote vehicle upgrades are prohibited, effectively improving the accuracy and reliability of remote vehicle upgrades.

[0055] In step S103, if the target upgrade process, target diagnostic communication type, and target security access algorithm in the target data domain are all within the preset upgrade conditions, then the vehicle is remotely upgraded using the upgrade file.

[0056] It is understood that, in the embodiments of this application, if the target upgrade process, target diagnostic communication type and target secure access algorithm in the target data domain are all within the upgrade conditions, then the vehicle can be remotely upgraded using the upgrade file, which effectively improves the correctness of the vehicle remote upgrade and enhances the vehicle's security.

[0057] Optionally, in one embodiment of this application, after disallowing remote vehicle upgrades, the method further includes: generating an upgrade failure report based on the target data domain that is not within the preset upgrade conditions, and sending the report to a preset terminal.

[0058] In actual implementation, the embodiments of this application can automatically generate an upgrade failure report based on the target data domain that is not within the upgrade conditions, and send the report to a preset terminal, such as the vehicle terminal or the user's mobile phone, thereby improving the vehicle's intelligence level and interactivity.

[0059] It should be noted that the preset terminal is set by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0060] Optionally, in one embodiment of this application, after performing a remote vehicle upgrade using the upgrade file, the method further includes: sending a remote vehicle upgrade reminder to a preset terminal.

[0061] For example, when a vehicle is undergoing a remote upgrade, this application embodiment can send a remote upgrade reminder to the user's mobile phone, thereby effectively improving the vehicle's interactivity.

[0062] like Figure 3 As shown below, the working principle of the embodiments of this application will be described in detail with a specific example.

[0063] Step S301: Read the contents of the SOrecord data field in the S19 file. That is, in this embodiment of the application, the upgrade process, diagnostic communication type and security access algorithm in the SOrecord data field of the S19 file can be read.

[0064] Step S302: Detect whether the upgrade process in the S0 Record data field is within the range of 0x00 (EEA1.0)-0x02 (EEA3.0). If the upgrade process is within the range, proceed to step S303; otherwise, proceed to step S306.

[0065] Step S303: Detect whether the diagnostic communication type in the S0 Record data field is within the range of 0x00 (CAN)-0x01 (Eth). If the diagnostic communication type range is met, proceed to step S304; otherwise, proceed to step S306.

[0066] Step S304: Detect whether the secure access algorithm in the S0 Record data field is within the range of 0x00 (algorithm 1) to 0x02 (algorithm 3). If the secure access algorithm range is met, proceed to step S305; otherwise, proceed to step S306.

[0067] Step S305: Identify the upgrade process, diagnostic communication type, and secure access algorithm used by the controller to perform remote vehicle upgrades, thereby improving the accuracy of remote vehicle upgrades.

[0068] Step S306: Exit upgrade. If the upgrade process, diagnostic communication type and secure access algorithm in the data domain are not within the upgrade conditions, remote vehicle upgrade is prohibited, thus improving the reliability of remote vehicle upgrade.

[0069] The vehicle remote upgrade method proposed in this application can download upgrade files for at least one target controller from a preset OTA server, obtain the target data field from the upgrade file, and check whether the target upgrade process, target diagnostic communication type, and target security access algorithm in the target data field are all within preset upgrade conditions. If they are all within the preset upgrade conditions, the vehicle is remotely upgraded using the upgrade file, thereby ensuring the correctness of the upgrade process during remote upgrades, improving the vehicle's intelligence level, and enhancing the user's driving experience. This solves the problem in related technologies where the upgrade process, communication method, and security access algorithm used by each controller differ, making it impossible to ensure the correctness of the upgrade process during remote upgrades, thus reducing the vehicle's intelligence level and the user's driving experience.

[0070] Next, the vehicle remote upgrade device according to an embodiment of this application is described with reference to the accompanying drawings.

[0072] like Figure 4 As shown, the vehicle remote upgrade device 10 includes: an acquisition module 100, a detection module 200, and a control module 300.

[0073] Specifically, the acquisition module 100 is used to download an upgrade file for at least one target controller from a preset OTA server and acquire the target data field in the upgrade file.

[0074] The detection module 200 is used to read the target upgrade process, target diagnostic communication type and target security access algorithm in the target data domain, and to detect whether the target upgrade process, target diagnostic communication type and target security access algorithm in the target data domain are all within the preset upgrade conditions.

[0077] Optionally, in one embodiment of this application, the detection module 200 includes: a first detection unit, a second detection unit, and a third detection unit.

[0078] The first detection unit is used to detect whether the data information of the target upgrade process in the file of SORecord data field meets the process range of the preset upgrade conditions. If the process range is met, the target upgrade process is determined to meet the preset upgrade conditions.

[0079] The second detection unit is used to detect whether the target diagnostic communication type in the file of the SORecord data field meets the range of diagnostic communication types under the preset upgrade conditions. If it meets the range of diagnostic communication types, the target diagnostic communication type is determined to meet the preset upgrade conditions.

[0080] The third detection unit is used to detect whether the target secure access algorithm in the file in the SORecord data field meets the preset upgrade conditions for the secure access algorithm range. If it meets the secure access algorithm range, the target secure access algorithm is determined to meet the preset upgrade conditions.

[0081] Optionally, in one embodiment of this application, the detection module 200 further includes a control unit.

[0082] The control unit is used to prohibit remote vehicle upgrades if the target upgrade process, target diagnostic communication type, and target security access algorithm in the target data domain are not within the preset upgrade conditions.

[0083] Optionally, in one embodiment of this application, the apparatus 10 of this application embodiment further includes: a generation module.

[0084] The generation module is used to generate an upgrade failure report based on the target data field that is not within the preset upgrade conditions after remote vehicle upgrades are not permitted, and then send the report to the preset terminal.

[0085] Optionally, in one embodiment of this application, the apparatus 10 of this embodiment further includes a sending module.

[0086] The sending module is used to send a remote vehicle upgrade reminder to a preset terminal after the vehicle is remotely upgraded using the upgrade file.

[0087] Optionally, in one embodiment of this application, both the target diagnostic communication type and the target secure access algorithm include at least one of diagnostic ID, data length, and data stream.

[0088] It should be noted that the foregoing explanation of the vehicle remote upgrade method embodiment also applies to the vehicle remote upgrade device of this embodiment, and will not be repeated here.

This solves the problem in related technologies where the upgrade process, communication method, and security access algorithm used by each controller differ, making it impossible to ensure the correctness of the upgrade process during remote upgrades, thus reducing the vehicle's intelligence level and the user's driving experience.
