The present application is capable of other and different embodiments and its several details are capable of modifications and/or changes in various respects, all without departing from the spirit of the present application. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present disclosure.

In the following description, numerous details are set forth to provide a more thorough explanation of the embodiments of the present application, however, it will be apparent to one skilled in the art that the embodiments of the present application may be practiced without these specific details, and in other embodiments, well-known structures and devices are shown in block diagram form rather than in detail in order to avoid obscuring the embodiments of the present application.

It should be noted that, at present, network management commonly used in automobiles is generally global network management, that is, when a certain function is activated, all nodes (Electronic Control units, ECUs, electronic Control units, controllers) participating in network management on the network need to be woken up, even if some nodes do not participate in the activation of the function. As functions on vehicles become more and more complex, local Network management (PN) has a greater advantage than global Network management. Unlike the logic that all nodes wake up simultaneously in global network management, local network management divides the entire network into a plurality of PN groups according to functional attributes, and these PN groups can be regarded as virtual local networks. One or more nodes are awakened through the network management message instead of all nodes on the bus, the nodes of the virtual local networks can be in the same network segment or cross the network segment, and the same node can also belong to a plurality of PN groups. It should be appreciated that in the embodiments of the present application, the PN group is consistent with the local network cluster group, and the PN parameter set is consistent with the local network cluster data group. Although the prior local network management technology realizes only waking up part of network segments or part of controllers, the possibility of waking up unrelated network segments or unrelated controllers still exists, for example, when a node spans multiple network segments, once the node is woken up, the node can cause all the segments spanned by the node to be woken up, thereby causing some unrelated network segments and unrelated controllers to be woken up. To solve these problems, embodiments of the present application respectively provide a local network management grouping method, a local network management grouping apparatus, an electronic device, a computer-readable storage medium, and a computer program product based on automotive local network management, which will be described in detail below.

The computer device 102 is operable to respond to a vehicle wake-up event and to invoke a target controller in accordance with the vehicle wake-up event. The remote sending terminal 103 may be any remote device supporting sending of a remote network management message, such as a smart phone, a tablet computer, a notebook computer, a microcomputer, a smart watch, and a smart car key. The remote sending end 103 and the automobile 101 are configured to send a vehicle wake-up event, where the remote sending end 103 sends a remote wake-up network management message to the computer device 102, and the automobile 101 sends information of a local wake-up source to the computer device 102, so that the computer device 102 performs subsequent execution.

Illustratively, the computer device 102, in response to a vehicle wake-up event, determines a current local network cluster data set according to the vehicle wake-up event, divides the current local network cluster data set according to a byte number to obtain a preset network segment, so as to perform primary matching on the current local network cluster data set and the preset network segment, if the matching is successful, transmits the current local network cluster data set to a target network segment, configures a controller mask to perform secondary matching on the current local network cluster data set and a preset controller in the target network segment, and calls a target controller according to a secondary matching result. Therefore, the technical scheme of the embodiment of the application can determine and awaken the target network segment and the target controller through the vehicle awakening event, reduces awakening of irrelevant network segments and a non-controller, saves energy consumption, can be suitable for various vehicle types, and is high in transportability.

It should be noted that the local network management grouping method provided in the embodiment of the present application is generally executed by the computer device 102, and accordingly, the local network management grouping apparatus is generally disposed in the computer device 102.

Referring to fig. 2, fig. 2 is a flowchart illustrating a local network management grouping method according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in FIG. 1 and specifically executed by the computer device 102 in the implementation environment. It should be understood that the method may be applied to other exemplary implementation environments and is specifically executed by devices in other implementation environments, and the embodiment does not limit the implementation environment to which the method is applied.

The current PN parameter set can be extracted from the network management message in the vehicle wake-up event; and setting the PN parameters corresponding to the preset functional scene to obtain the current PN parameter group by identifying the preset functional scene with a mapping relation with the vehicle awakening event. It should be understood that the routing gateway ECU is a preset controller having a gateway function among the preset controllers; the vehicle wake-up event may include a wake-up event set by a person skilled in the art, such as KL15 power-on, hard-line wake-up, timer, sensor, CAN (Controller Area Network) wake-up, and the like; the preset function scenario is set in advance by a person skilled in the art.

If the PNI value meets a preset identification threshold value, awakening and executing response; and if the PNI value does not meet the preset identification threshold value, keeping the sleep. Illustratively, the predetermined flag threshold may be 1, or other values set by those skilled in the art.

And carrying out network segment distribution according to the division result to obtain a preset network segment. And matching the current PN parameter set with the preset network segment for one time. If the matching is successful, determining the successfully matched preset network segment as a target network segment, and sending a network management message carrying the current PN parameter set to the target network segment so that a preset controller on the target network segment receives the network management message. And if the matching fails, not sending the network management message to the preset network segment with the failed matching. In the embodiment, the target network segment is obtained by matching the current PN parameter set with the preset network segment so as to send the network management message carrying the current PN parameter to the target network segment, thereby achieving the effect of isolating the network segment, namely only waking up the related network segment (the target network segment) and keeping the sleep state of the unrelated network segment continuously.

In one embodiment of the present application, step S220 includes the steps of:

and step S221, obtaining each local network cluster according to the division result, and distributing each local network cluster to each network segment.
