In the embodiment of the present invention, the subscription confirmation response is used to indicate that the target service providing device allows the execution device to subscribe to the target refresher function service, that is, after the target service providing device feeds back the subscription confirmation response or the execution device receives the subscription confirmation response fed back by the target service providing device, the target service providing device and the execution device establish a service providing function. The type of the subscription confirmation response may be a message type, that is, the subscription confirmation response may be specifically a subscription confirmation message.

206. The execution device receives a subscription confirmation response.

207. The execution device transmits the software upgrade package of the target vehicle-mounted ECU to the target service providing device.

208. The target service providing device receives the software upgrade package of the target vehicle-mounted ECU, and executes a software upgrade process for the target vehicle-mounted ECU according to the software upgrade package of the target vehicle-mounted ECU.

In the embodiment of the present invention, the software upgrade process is mainly a software upgrade process based on UDS (Unified Diagnostic Services), which mainly includes reading various version numbers of the above-mentioned target vehicle-mounted ECU, DTC (Diagnostic Trouble Code) settings, communication settings, entering programming mode, data transmission, erase instructions and integrity verification, etc., which are not limited in the embodiment of the present invention.

It should be noted that for other detailed descriptions of the execution device, the target service providing device and other detailed descriptions of the steps executed by the execution device and the target service providing device, reference can be made to the relevant descriptions in Embodiment 1, and the embodiments of the present invention will not be repeated here.

In an optional embodiment, after executing step 203, the execution device may further perform the following operations:

The execution device detects whether a subscription confirmation response fed back by the target service provider device is received within a certain time period starting from the time of sending the subscription request. If the subscription confirmation response is not received, the subscription is confirmed to have failed, and step 203 can be triggered to execute. The duration of the certain time period is preset.

In this optional embodiment, further optionally, after the execution device confirms that the subscription fails and before re-triggering the execution of step 203, the execution device may further perform the following operations:

When it is determined that the service required by the execution device is one of at least one service that the target service provider device can provide, the execution device is determined to be a legally subscribed execution device.

It can be seen that this optional embodiment can also verify the legitimacy of the subscription of the execution device sending the subscription request according to the content included in the subscription request after the service providing device receives the subscription request, which is beneficial to improving the accuracy of the service providing function established by the service providing device and the execution device.

For example, the software upgrade of the air-conditioning controller (CAN refresh) and the panoramic controller (Ethernet refresh) through OTA is used to illustrate. Among them, Tbox is the executor (that is, the execution device) for subscription services and refresh distribution functions, the gateway provides CAN refresh machine function services and Ethernet refresh machine function services, and the instrument controller provides Ethernet refresh machine function services. The specific process is described as follows.

The software upgrade of the air conditioning controller (CAN refresh) via OTA mainly includes the following processes:

Step S01: The gateway periodically sends a message providing a CAN flash machine function service;

Step S02: Tbox receives a software upgrade instruction for upgrading the air-conditioning controller;

Step S03: Tbox subscribes to the gateway CAN refresh machine function service, that is, Tbox sends a subscription message to the gateway;

Step S04: The gateway receives the subscription message and confirms the subscription. After confirmation, it sends a subscription confirmation message to Tbox. Tbox receives the subscription confirmation message and completes the subscription process. If Tbox does not receive the subscription confirmation message from the gateway within the specified time, the subscription fails and it is necessary to return to step S03. This process is repeated N times (N is a configurable number, such as 3). If the subscription still fails after N times, Tbox will choose to subscribe to other controllers that can provide CAN refresher function and start subscription again.

Step S05: Tbox transmits the air conditioner controller upgrade software package to the gateway;

Step S06: The gateway receives and saves;

Step S07: The gateway acts as a CAN refresher to perform a software upgrade process on the air-conditioning controller. This process is mainly based on the software upgrade process of UDS update, and mainly includes reading various version numbers of the air-conditioning controller, DTC settings, communication settings, entering programming mode, data transmission, erasing instructions, integrity verification and other processes;

Step S08: The air conditioning controller software upgrade is completed.

And, software upgrade of the panoramic controller via OTA (Ethernet refresh) includes the following process:

Step S11: The gateway and the instrument controller periodically send messages providing Ethernet refresh machine function services;

Step S12: Tbox receives a software upgrade instruction for upgrading the panoramic controller;

Step S13: Tbox selects one of the gateways or instrument controllers to subscribe to the Ethernet refresh machine function service according to its own strategy. Taking the gateway as an example to subscribe to the Ethernet refresh machine function service, Tbox sends a subscription message to the gateway;

Step S14: The gateway receives the subscription message and confirms the subscription. After confirmation, it sends a subscription confirmation message to Tbox. Tbox receives the subscription confirmation message and completes the subscription process. If Tbox does not receive the subscription confirmation message from the gateway within the specified time, the subscription fails and it needs to return to step 03. This process is repeated N times (N is a configurable number, such as 3). If the subscription still fails after N times, Tbox will choose to subscribe to other controllers that can provide Ethernet refresh machine function (such as instrument controller) and start subscription again.

Step S15: Tbox transmits the panoramic controller upgrade software package to the gateway;

Step S16: The gateway receives and saves;

Step S17: The gateway acts as an Ethernet refresher to perform a software upgrade process on the panoramic controller. This process is mainly based on the software upgrade process updated by UDS, and mainly includes reading various version numbers of the panoramic controller, DTC settings, communication settings, entering programming mode, data transmission, erasing instructions, integrity verification and other processes;

Step S18: The panoramic controller software upgrade is completed.

It can be seen that the service-oriented vehicle ECU software upgrade method described in the embodiment of the present invention can be implemented by the execution device (also understood as the upgrade end) to subscribe to the refresh machine function service and obtain the software upgrade package, and the service providing device (such as the ECU with the refresh machine function) that provides the refresh machine function service publishes the service to the execution device, and after confirming the software upgrade, the execution device sends the acquired software upgrade package to the service providing device that provides the refresh machine function service for software upgrade, that is: providing a service-oriented software upgrade strategy, adding the subscription and publishing operations of the refresh machine function service before the software upgrade, and providing a more flexible, safer and more configurable software upgrade method for the whole vehicle ECU software upgrade. In addition, it can also enable the execution device to confirm the refresh machine function service provided by different service providing devices in advance, which is conducive to the execution device to quickly and accurately select the appropriate service providing device to subscribe to the refresh machine function service when determining that a certain vehicle ECU needs to be upgraded.
