Gateway Device Group Mapping for Selective Vehicle Network Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle network systems, electronic control devices that do not support partial networks are activated unnecessarily, leading to increased power consumption.
Innovation Solution
A gateway device is introduced to manage communication between electronic control devices, using a correspondence map to identify groups of devices and relay activation requests only to networks containing devices that need to be activated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If activation request messages are transmitted without including specific frame information, then electronic control devices can be activated, but unnecessary devices are also activated leading to increased power consumption
Solution Approach 1:
The gateway device acts as an intermediary between the transmission source and electronic control devices. It receives activation request messages, determines the appropriate group based on the transmission source, and selectively relays messages only to relevant networks. This prevents unnecessary activation of devices while maintaining ease of operation for the transmission source.
Solution Approach 2:
The system applies different activation behaviors to different groups of electronic control devices based on their network affiliation. The gateway device determines which group the transmission source belongs to and selectively activates only devices within that group, rather than broadcasting to all devices universally.
2Adaptability or versatility
If activation request messages are broadcast to all networks, then all electronic control devices can receive activation requests, but devices in unrelated networks are unnecessarily activated
Solution Approach 1:
The electronic control devices are divided into different groups based on network affiliation. The gateway device segments the activation request relay process by determining which group the transmission source belongs to and only relaying messages to networks containing devices from that group. This segmentation prevents energy waste while maintaining adaptability.
3Adaptability or versatility
If electronic control devices without partial network adaptation are used, then device compatibility is improved, but unnecessary activation occurs increasing power consumption
Solution Approach 1:
The gateway device serves as a mediator that bridges devices with and without partial network adaptation. It receives activation requests from incompatible devices, determines the appropriate group, and selectively relays requests only to relevant networks, preventing unnecessary activation of devices while maintaining broad compatibility.

AI summary
The storage device stores a correspondence map. The correspondence map indicates a correspondence relationship between a plurality of groups, an electronic control device belonging to the group, and a network constituted by the electronic control device. The execution device refers to the correspondence map and identifies a group to which the node information included in the received activation request message belongs. The execution device determines a network including an electronic control device belonging to the specified group as a relay destination, without using a network including an electronic control device belonging to the specified group as a relay bond.
