In-Vehicle Network Configuration for Non-Communicating Functional Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management devices struggle to generate configuration information for a new in-vehicle network when a newly added functional unit lacks the ability to transmit functional unit information.
Innovation Solution
A management device that includes a detection unit to identify new functional units, an acquisition unit to gather functional unit information, and a generation unit to create configuration information using candidate information and feasibility data, even if the new unit cannot transmit its own information, thereby constructing a reliable new network configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the management device requires the new functional unit to transmit its own functional unit information, then the network configuration can be automatically generated, but the new functional unit must have transmission capability which may not be available
Solution Approach 1:
The management device acts as an intermediary by providing a manual input interface for users to input functional unit information when automatic acquisition fails. This intermediary approach bridges the gap between automated configuration generation and compatibility with functional units that cannot transmit their own information, allowing the system to adapt to both scenarios.
Solution Approach 2:
The system performs preliminary detection to determine whether the new functional unit has transmission capability before attempting automatic information acquisition. Based on this preliminary assessment, the system prepares appropriate acquisition methods in advance, switching between automatic and manual input modes as needed.
2Adaptability or versatility
If the system supports functional units without transmission capability, then versatility is improved, but user input burden and error complexity increase
Solution Approach 1:
The management device serves as an intermediary that simplifies the user input process by providing a structured manual input interface. This intermediary layer guides users through the information input process, reducing the burden and potential for errors compared to direct complex configuration procedures.
3Ease of operation
If automatic information acquisition is used, then ease of operation is improved, but reliability fails when the new functional unit cannot transmit information
Solution Approach 1:
The system implements feedback by detecting whether the new functional unit has transmission capability and adjusting the information acquisition method accordingly. When automatic acquisition fails, the system provides feedback to switch to manual input mode, ensuring reliable configuration generation regardless of the functional unit's capabilities.
Solution Approach 2:
The information acquisition mechanism is made dynamic, automatically switching between automatic acquisition and manual input modes based on the detected capabilities of the new functional unit. This dynamic adaptation ensures both ease of operation and reliability in different scenarios.

AI summary
A management device that includes a processor that is configured to: detect addition of a functional unit to a network including one or more in-vehicle functional units; acquire functional unit information of the one or more in-vehicle functional units, acquire target information which is functional unit information of a new functional unit which is the functional unit whose addition was detected, and, when the target information cannot be acquired from the new functional unit, transmit candidate information indicating a candidate for the target information and acquire the target information by receiving a selection result indicating a candidate indicated by the candidate information; and generate configuration information for a new network which is the network further including the new functional unit, based on the functional unit information acquired.
