Vehicle Control Device Modular Interface Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control devices face difficulties in easy assembly, detachment, maintenance, and inspection due to complex arrangements of signal lines and power lines, which complicate electromagnetic compatibility (EMC) selection and hinder efficient emergency repairs.
Innovation Solution
The vehicle control device is designed with functional modules that have separate interface surfaces for signal lines and power lines, where signal line terminals are concentrated in one area and power line terminals in another, allowing for simplified wiring and streamlined maintenance operations by facing interface surfaces in the same direction.

1Object-affected harmful factors
If signal lines and power lines are separately arranged on different side surfaces, then electromagnetic compatibility is improved, but assembly and maintenance operations become more difficult
Solution Approach 1:
The interface surface is segmented into distinct first interface areas for signal line terminals and second interface areas for power line terminals. This spatial segmentation maintains electromagnetic compatibility by separating signal and power connections while consolidating all connections on one side surface, enabling easy assembly and maintenance operations from a single access point.
2Productivity
If wiring paths are simplified by concentrating terminals, then manufacturing efficiency is improved, but wiring path length may increase
Solution Approach 1:
All signal line terminals and power line terminals are merged and concentrated on a single side surface of the functional module through divided interface areas. This merging enables wiring operations to be completed from one location, significantly improving manufacturing efficiency and productivity while the structured layout optimizes wire routing to minimize path length increases.

AI summary
A vehicle control device includes plural functional modules each of which is a minimum part unit that contributes to change in input/output potentials, and has an input and an output of one power line or one set of power lines, except for power lines having a same potential as that on an overhead wire side or that on a ground side. The functional module has an interface surface on one side surface, to which both of a signal line and the power line are connected. Each interface surface is divided into a first interface area in which a signal line terminal connected to the signal line is placed, and a second interface area in which a power line terminal connected to the power line is placed. The plural functional modules are adjacently arranged such that the interface surfaces face in a same direction, the first interface areas are located on one end side in common, and the second interface areas are located on the other end side in common.
