In the embodiment of the invention, before the service providing equipment and the executing equipment establish the service providing function, part or all of the service providing equipment can periodically or irregularly issue the corresponding refreshing machine function service to the executing equipment, so that the executing equipment can confirm the refreshing machine function service provided by different service providing equipment in advance, and the executing equipment can quickly and accurately select the proper service providing equipment to subscribe the refreshing machine function service when determining that a certain vehicle-mounted ECU needs to be upgraded.
202. The execution device detects whether a software upgrading instruction aiming at the target vehicle-mounted ECU is received, and when the detection result is negative, the flow can be ended, and the execution step 202 can be triggered continuously; when the detection result is yes, execution of step 203 may be triggered.
In the embodiment of the invention, the software upgrading instruction is used for indicating the target vehicle-mounted ECU to carry out software upgrading, namely the target vehicle-mounted ECU is any vehicle-mounted ECU which needs to carry out software upgrading, such as an air conditioner controller or a panoramic controller.
203. The execution device sends a subscription request to the target service providing device to request subscription to the target refresh function service matched with the target vehicle-mounted ECU.
Wherein the target service providing device is one of a plurality of service providing devices and is used for providing the target refresh function service, the type of the subscription request may be a message type, that is, the subscription request may be a subscription message.
204. The target service providing device receives the subscription request.
In the embodiment of the present invention, after receiving the subscription request, the target service providing device may first confirm the subscription request, and after confirming the subscription request, trigger to execute step 205. If the subscription request cannot be confirmed, the target service providing device may not respond, or may feedback a subscription invalid response or a subscription rejection response, so that the executing device may send a subscription request meeting the requirements in time or select other suitable service providing devices to subscribe to the target refresh machine function service.
205. The target service providing device feeds back a subscription confirmation response matched with the subscription request to the executing device.
In the embodiment of the invention, the subscription confirmation response is used for indicating that the target service providing device allows the executing device to subscribe to the target refreshing machine function service, namely, after the target service providing device feeds back the subscription confirmation response or the executing device receives the subscription confirmation response fed back by the target service providing device, the target service providing device and the executing device establish the 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 executing device receives the 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 upgrading package of the target vehicle-mounted ECU and executes the software upgrading flow aiming at the target vehicle-mounted ECU according to the software upgrading package of the target vehicle-mounted ECU.
In the embodiment of the invention, the software upgrading process is mainly a software upgrading process based on UDS (Unified Diagnostic Services, unified diagnostic service) updating, and mainly comprises processes of reading various version numbers of the target vehicle-mounted ECU, setting of DTCs (Diagnostic Trouble Code, diagnostic fault codes), communication setting, entering a programming mode, data transmission, erasing instructions, integrity verification and the like.
It should be noted that, for other detailed descriptions of the execution device and the target service providing device, and for other detailed descriptions of the steps executed by the execution device and the target service providing device, reference may be made to the related descriptions in the first embodiment, which is not repeated in the embodiments of the present invention.
In an alternative embodiment, after performing the finishing step 203, the execution device may further perform the following operations:
The executing device detects whether a subscription confirmation response fed back by the target service providing device is received within a certain period of time from the time when the subscription request is sent, if the subscription confirmation response is not received, the subscription is confirmed to be failed, and the executing device may continue to trigger the executing step 203. Wherein the duration of the certain time period is preset.
In this alternative embodiment, further optionally, after the execution device confirms the subscription failure, and before the execution step 203 is re-triggered, the execution device may further perform the following operations:
the execution device judges whether the accumulated number of subscription failures reaches or exceeds the preset number, and when the judgment result is negative, the execution device continues to trigger the execution step 203; when the determination result is yes, the current flow may be ended, or another service providing device capable of providing the target refresh function service may be selected as a new target service providing device, and the execution of step 203 may be retried.
It can be seen that, in this alternative embodiment, whether to continue to execute step 203 can be determined according to the accumulated number of subscription failures after the subscription failure, so as to implement subscription control on the executing device, and when the accumulated number of subscription failures is greater, the executing device may automatically select other service providing devices to subscribe, so as to reduce the problems of low subscription success rate and low subscription efficiency caused by the subscription failure and continuous transmission of the subscription request to the same service providing device.
In another alternative embodiment, the method may further comprise the following operations, before the completing step 203 is performed:
the execution device determines the target type of the service to be subscribed to;
The execution device selects a service providing device capable of providing the service of the target type as the target service providing device according to the target type, and triggers the execution of the above-mentioned operation of sending a subscription request to the target service providing device to request subscription to the target refresh function service matched with the target vehicle-mounted ECU.
Therefore, before the subscription request is sent, the optional embodiment can select an appropriate service providing device to send the subscription request according to the type of the required subscription service, which is beneficial to improving the subscription success rate and the refresh function service provided or released by the service providing device after the subscription success rate to meet the software upgrading requirement of the vehicle-mounted ECU needing to carry out the software upgrading.
Optionally, the target refresh machine service may be one of a CAN refresh machine function service, an ethernet refresh machine function service, and a CAN-ethernet hybrid refresh machine function service, that is, a refresh machine function service that may be provided by a service providing device may include at least one of a CAN refresh machine function service, an ethernet refresh machine function service, and a CAN-ethernet hybrid refresh machine function service, which is not limited in the embodiment of the present invention.
