[0009] In a possible implementation of the present application, in response to an affirmative response instruction sent by the OTA platform, before sending a request upgrade instruction to the OTA platform, the method includes: determining whether the current network status of the vehicle meets the preset network status; if the current network status meets the preset network status, sending a request upgrade instruction to the OTA platform.

[0010] In a possible implementation of the present application, a request for upgrade instruction is sent to the OTA platform, and, in response to the upgrade instruction sent by the OTA platform, the ECU to be upgraded is upgraded, including: sending an nth request for upgrade instruction to the OTA platform, so that the OTA platform parses the file to be upgraded in the task to be upgraded and sends the upgrade instruction to the OTA controller; in response to the nth upgrade instruction sent by the OTA platform, sending the nth upgrade instruction to the ECU to be upgraded, so that the ECU to be upgraded is upgraded based on the nth upgrade instruction; the nth upgrade instruction includes the nth message information parsed from the file to be upgraded of the task to be upgraded; wherein n is a positive integer greater than or equal to 1.

[0023] Exemplary Method 1

[0024] As a first aspect of the present application, the present application provides an OTA upgrade method, which is applied to an OTA platform. Figure 1 FIG. 1 is a flow chart of an OTA upgrade method applied to an OTA platform provided by an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0025] S101, in response to a task query instruction sent by the OTA controller, determining whether there is a task to be upgraded;

[0026] Specifically, the above-mentioned OTA platform can be used to represent the cloud platform responsible for managing and executing remote software upgrade tasks in the automotive OTA technology system.

[0027] The above-mentioned OTA controller can be used to represent the vehicle-mounted system or module responsible for managing and executing remote software upgrade tasks in the automotive OTA technology system.

[0028] The above-mentioned task query instruction may be used to indicate an instruction to instruct or request the OTA platform to query whether there is a task to be upgraded.

[0029] The above-mentioned tasks to be upgraded can be used to indicate tasks that require upgrading of vehicle components, including but not limited to upgrading of vehicle hardware or software. The tasks to be upgraded are not specifically defined and can be adjusted according to actual conditions.

[0030] In an optional embodiment, during the OTA upgrade of the vehicle, the OTA controller first sends a task query instruction to the OTA platform. In response to receiving the task query instruction sent by the OTA controller, the OTA platform can determine whether there is a task to be upgraded. Generally, the judgment result includes two situations. When there is a task to be upgraded on the OTA platform, subsequent processing can be performed to upgrade the vehicle components; when there is no task to be upgraded, the OTA platform feeds back an upgrade end instruction to the OTA controller, which means that there is no need to upgrade the vehicle components.

[0031] In addition, before performing OTA upgrades on vehicle components, vehicle developers can create tasks to be upgraded in the OTA platform, so that based on the created tasks to be upgraded, subsequent instructions can be executed to upgrade the vehicle components.

[0032] S102, if there is a task to be upgraded, feeding back a positive response instruction to the OTA controller;

[0033] Specifically, the above-mentioned affirmative response instruction can be used as a feedback instruction indicating that there is a task to be upgraded in the OTA platform.

[0034] In an optional embodiment, when there are tasks to be upgraded in the OTA platform, the OTA platform may feedback an affirmative response instruction to the OTA controller, so that the OTA controller executes subsequent instructions to upgrade the vehicle-mounted components after receiving the affirmative response instruction.

[0035] Generally, the OTA platform may send a positive response instruction to the OTA controller via wireless network transmission.

[0036] S103, in response to the upgrade request instruction sent by the OTA controller, parsing the files to be upgraded in the upgrade task, and sending the upgrade instruction to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded.

[0037] Specifically, the above-mentioned upgrade request instruction can be used to indicate an instruction for requesting an OTA upgrade.

[0038] In an optional embodiment, after receiving the above-mentioned affirmative response instruction, the OTA controller sends an upgrade request instruction to the OTA platform, that is, requests an OTA upgrade. After receiving the upgrade request instruction, the OTA platform can parse the files to be upgraded in the upgrade task, and after the analysis is completed, send an upgrade instruction to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded. Among them, the parsing process of the files to be upgraded includes general methods in the field, and the parsing process is not described in detail here.

[0039] Specifically, parsing the upgrade file on the OTA platform, on the one hand, reduces the computing resource consumption of the vehicle system; on the other hand, after the OTA platform completes the parsing of the upgrade file, by sending an upgrade instruction to the OTA controller, the OTA controller can upgrade the ECU to be upgraded, reducing the OTA upgrade time and thereby improving the upgrade efficiency of vehicle components.

[0040] In addition, by parsing the upgrade files on the OTA platform, compared with the traditional method of parsing and downloading the upgrade files through the OTA controller, the waste of space resources for storing the downloaded files is avoided. That is, the upgrade files are parsed on the OTA platform, and there is no need to save the upgrade files locally, which reduces the storage resource dependence of the vehicle system and reduces hardware costs.

[0041] The OTA upgrade method provided by the present application is applied to the OTA platform, including: responding to the task query instruction sent by the OTA controller, judging whether there is a task to be upgraded; if there is a task to be upgraded, feeding back a positive response instruction to the OTA controller; responding to the request upgrade instruction sent by the OTA controller, parsing the files to be upgraded in the upgrade task, and sending an upgrade instruction to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded. It is easy to notice that by using the OTA platform to parse the files to be upgraded in the upgrade task, and after parsing the files to be upgraded, issuing a start upgrade instruction to upgrade the vehicle components, compared with the prior art, the process of downloading and parsing the upgrade package by the vehicle OTA controller is cancelled, thereby reducing the upgrade time of vehicle components, reducing hardware costs, and reducing computing resource consumption, thereby achieving the purpose of improving the upgrade efficiency of vehicle components, thereby solving the technical problems of increased hardware costs and reduced upgrade efficiency in the process of upgrading vehicle components.

[0042] In a possible implementation of the present application, if there is no task to be upgraded, a negative response is fed back to the OTA controller to confirm the termination of the OTA upgrade process.

[0043] Specifically, the above negative response may be used to indicate that there is no feedback result of the task to be upgraded on the OTA platform.

[0044] In an optional embodiment, after the OTA platform receives the upgrade request instruction, if it is determined that there is no task to be upgraded on the OTA platform, a negative response is fed back to the OTA controller, that is, there is no task to be upgraded on the OTA platform, and there is no need to execute subsequent OTA upgrade instructions, confirming the termination of the OTA upgrade process.

[0045] In a possible implementation of the present application, in response to an upgrade request instruction sent by the OTA controller, the files to be upgraded in the task to be upgraded are parsed, and the upgrade instruction is sent to the OTA controller, including: in response to the nth upgrade request instruction sent by the OTA controller, the nth upgrade instruction is fed back to the OTA controller; the nth upgrade instruction includes the nth message information parsed from the files to be upgraded in the task to be upgraded; wherein n is a positive integer greater than or equal to 1.

[0046] Specifically, the above-mentioned message information includes detailed information of the file to be upgraded, including but not limited to metadata, data content, verification information, serial number, timestamp and other information, and the message information is not specifically limited here.

[0047] In an optional embodiment, in response to a request upgrade instruction sent by the OTA controller, the files to be upgraded in the upgrade task are parsed, and the upgrade instruction is sent to the OTA controller. After the OTA platform receives the nth request upgrade instruction sent by the OTA controller, the nth upgrade instruction can be fed back to the OTA controller, wherein the nth upgrade instruction serves as a feedback instruction to the nth request upgrade instruction.

[0048] In addition, if the files to be upgraded in the upgrade task have not been upgraded, the nth upgrade instruction includes the nth message information parsed from the files to be upgraded; if the files to be upgraded in the upgrade task have been upgraded, the nth upgrade instruction includes the completion of upgrading the files to be upgraded.

[0049] Figure 2 FIG. 1 is a flow chart of a vehicle OTA upgrade process provided by an embodiment of the present application. When the OTA upgrade method is applied to an OTA platform, as shown in FIG. Figure 2 As shown in the figure, the OTA platform performs the following steps during the OTA upgrade process:

[0050] a1, create a task;

[0051] Vehicle developers can create tasks to be upgraded in the OTA platform.

[0052] a2, task query;

[0053] After receiving the task query instruction sent by the OTA controller, the OTA controller is fed back with an instruction indicating the existence of the OTA task, so that the OTA controller upgrades the ECU to be upgraded;

[0054] a3, after receiving the upgrade request instruction sent by the OTA controller, sending a start upgrade instruction to the OTA controller, so that the OTA controller starts upgrading the ECU to be upgraded;

[0055] a4, after receiving the first upgrade request instruction sent by the OTA controller, parsing the file to be upgraded in the upgrade task, and sending the first upgrade instruction to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded based on the first upgrade instruction, wherein the first upgrade instruction includes first message information obtained by parsing the file to be upgraded;

[0056] a5, after receiving the second upgrade request instruction sent by the OTA controller, parsing the file to be upgraded in the upgrade task, and sending a second upgrade instruction to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded based on the second upgrade instruction, wherein the second upgrade instruction includes second message information obtained by parsing the file to be upgraded;

[0057] a6, and so on, until the nth request upgrade instruction sent by the OTA controller is received. If the upgrade of the file to be upgraded is completed at this time, an upgrade end instruction is sent to the OTA controller to confirm the completion of the OTA upgrade. On the contrary, if the upgrade of the file to be upgraded is not completed at this time, the nth upgrade instruction is continued to be sent to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded based on the nth upgrade instruction until the completion of the OTA upgrade is confirmed.

[0058] Exemplary Method 2

[0059] As a second aspect of the present application, the present application also provides an OTA upgrade method, which is applied to an OTA controller. Figure 3 FIG. 1 is a flow chart of an OTA upgrade method applied to an OTA controller provided by an embodiment of the present application. Figure 3 As shown, the method includes:

[0060] S301, sending a task query instruction to the OTA platform, so that the OTA platform determines whether there is a task to be upgraded;

[0061] Specifically, during the vehicle OTA upgrade process, a task query instruction can be sent from the vehicle-mounted OTA controller to the cloud-based OTA platform, so that the OTA platform can query whether there is a task to be upgraded based on the task query instruction.

[0062] S302, in response to the positive response instruction sent by the OTA platform, sending an upgrade request instruction to the OTA platform, so that the OTA platform parses the files to be upgraded in the upgrade task and sends the upgrade instruction to the OTA controller; wherein the positive response instruction is sent by the OTA platform to the OTA controller when it is determined that there is a task to be upgraded;

[0063] Specifically, if an affirmative response instruction is received from the OTA platform, indicating that there is a task to be upgraded in the OTA platform, a request upgrade instruction is sent to the OTA platform, so that the OTA platform performs cloud-based parsing of the file to be upgraded based on the received request upgrade instruction, and sends an upgrade instruction to the OTA controller, wherein the upgrade instruction includes the message information obtained by parsing the file to be upgraded.

[0064] S303, in response to the upgrade instruction sent by the OTA platform, upgrading the ECU to be upgraded.

[0065] Specifically, after receiving the upgrade instruction sent by the OTA platform, the ECU to be upgraded can be upgraded based on the upgrade instruction. Specifically, the ECU to be upgraded can be upgraded based on the message information carried in the upgrade instruction.

[0066] The OTA upgrade method provided by the present application is applied to the OTA controller, including: sending a task query instruction to the OTA platform so that the OTA platform determines whether there is a task to be upgraded; in response to the positive response instruction sent by the OTA platform, sending a request upgrade instruction to the OTA platform so that the OTA platform parses the files to be upgraded in the upgrade task and sends the upgrade instruction to the OTA controller; wherein the positive response instruction is sent by the OTA platform to the OTA controller when it is determined that there is a task to be upgraded; in response to the upgrade instruction sent by the OTA platform, the ECU to be upgraded is upgraded. It is easy to notice that by using the OTA platform to parse the files to be upgraded in the upgrade task, and after parsing the files to be upgraded, issuing a start upgrade instruction to upgrade the vehicle-mounted components, compared with the prior art, the process of downloading and parsing the upgrade package by the vehicle-mounted OTA controller is cancelled, thereby reducing the upgrade time of vehicle components, reducing hardware costs, and reducing computing resource consumption, thereby achieving the purpose of improving the upgrade efficiency of vehicle components, thereby solving the technical problems of increased hardware costs and reduced upgrade efficiency in the process of upgrading vehicle components.

[0067] In a possible implementation of the present application, in response to an affirmative response instruction sent by the OTA platform, before sending a request upgrade instruction to the OTA platform, the method includes: determining whether the current network status of the vehicle meets the preset network status; if the current network status meets the preset network status, sending a request upgrade instruction to the OTA platform.

[0068] Specifically, the above-mentioned preset network status can be used to represent the pre-set vehicle network status that meets the upgrade conditions, including but not limited to performance indicators such as network rate and network delay. The preset network status is not specifically set here and can be adjusted according to actual conditions.

[0069] In an optional embodiment, before sending a request for upgrade instruction to the OTA platform, it can be determined whether the current network status of the vehicle satisfies the preset network status, that is, whether the current network status of the vehicle satisfies the upgrade conditions. If the current network status of the vehicle satisfies the preset network status, that is, it means that the current network status of the vehicle satisfies the upgrade conditions, then a request for upgrade instruction is sent to the OTA platform; conversely, if the current network status of the vehicle does not satisfy the preset network status, that is, it means that the current network status of the vehicle does not meet the upgrade conditions, then a request for upgrade instruction is not sent to the OTA platform for the time being. After the current network status of the vehicle meets the upgrade conditions, a request for upgrade instruction is sent to the OTA platform, so as to avoid the entire vehicle OTA upgrade process being affected by the vehicle network status.

[0070] In a possible implementation of the present application, a request for upgrade instruction is sent to the OTA platform, and, in response to the upgrade instruction sent by the OTA platform, the ECU to be upgraded is upgraded, including: sending an nth request for upgrade instruction to the OTA platform, so that the OTA platform parses the file to be upgraded in the task to be upgraded and sends the upgrade instruction to the OTA controller; in response to the nth upgrade instruction sent by the OTA platform, sending the nth upgrade instruction to the ECU to be upgraded, so that the ECU to be upgraded is upgraded based on the nth upgrade instruction; the nth upgrade instruction includes the nth message information parsed from the file to be upgraded of the task to be upgraded; wherein n is a positive integer greater than or equal to 1.

[0071] Specifically, in the process of sending a request for upgrade instruction to the OTA platform and, in response to the upgrade instruction sent by the OTA platform, upgrading the ECU to be upgraded, an nth request for upgrade instruction may be sent to the OTA platform, so that the OTA platform parses the file to be upgraded in the task to be upgraded after receiving the nth request for upgrade instruction and sends the nth upgrade instruction to the OTA control; after receiving the nth upgrade instruction sent by the OTA platform, the nth upgrade instruction may be sent to the ECU to be upgraded, so that the ECU to be upgraded is upgraded based on the nth upgrade instruction, wherein the nth upgrade instruction includes the nth message information parsed from the file to be upgraded of the task to be upgraded, that is, the nth upgrade instruction is sent to the ECU to be upgraded, so that the ECU to be upgraded is upgraded based on the nth upgrade instruction.

[0072] For example, when the OTA upgrade method is applied to the OTA controller, as described above Figure 2 As shown, the OTA controller performs the following steps during the OTA upgrade process:

[0073] b1, sending a task query instruction to the OTA platform, so that the OTA platform queries whether there is a task to be upgraded;

[0074] b2, in response to receiving a feedback instruction from the OTA platform indicating the existence of an OTA task, checking whether the current network status of the vehicle meets the upgrade conditions;

[0075] b3, if the current network status of the vehicle meets the upgrade conditions, send an upgrade request instruction to the OTA platform;

[0076] b4, in response to receiving the start upgrade instruction sent by the OTA platform, sending a first request upgrade instruction to the OTA platform, so that the OTA platform parses the file to be upgraded based on the first request upgrade instruction and sends the first upgrade instruction to the OTA controller;

[0077] b5, in response to receiving a first upgrade instruction sent by the OTA platform, sending the first upgrade instruction to the ECU to be upgraded, so that the ECU to be upgraded is upgraded based on the first upgrade instruction;

[0078] b6, in response to receiving the first positive response instruction fed back by the ECU to be upgraded, sending a second upgrade request instruction to the OTA platform, so that the OTA platform parses the file to be upgraded based on the second upgrade request instruction and sends the second upgrade instruction to the OTA controller;

[0079] b7, in response to receiving the second upgrade instruction sent by the OTA platform, sending the second upgrade instruction to the ECU to be upgraded, so that the ECU to be upgraded is upgraded based on the second upgrade instruction;

[0080] b8, and so on, until the nth request upgrade instruction is sent to the OTA platform, so that the OTA platform parses the upgrade file based on the nth request upgrade instruction and sends the nth upgrade instruction to the OTA controller. If the upgrade of the upgrade file is completed at this time, the received nth upgrade instruction is the end of the upgrade; otherwise, if the upgrade of the upgrade file is not completed at this time, the upgrade of the ECU to be upgraded is based on the received nth upgrade instruction until the OTA upgrade is confirmed to be completed.

[0085] S11, responding to the task query instruction sent by the OTA controller, determining whether there is a task to be upgraded;

[0086] S12, if there is a task to be upgraded, a positive response instruction is fed back to the OTA controller;

[0087] S13, in response to the upgrade request instruction sent by the OTA controller, parsing the files to be upgraded in the upgrade task, and sending the upgrade instruction to the OTA controller, so that the OTA controller upgrades the ECU to be upgraded.

[0088] In some implementations, the OTA platform is further configured to: if there is no task to be upgraded, feed back a negative response to the OTA controller to confirm the termination of the OTA upgrade process.

[0089] In some implementations, the OTA platform is also used to: in response to the nth request upgrade instruction sent by the OTA controller, feedback the nth upgrade instruction to the OTA controller; the nth upgrade instruction includes the nth message information parsed from the upgrade file of the task to be upgraded; wherein n is a positive integer greater than or equal to 1.
