Headlight Control Interface for User-Autonomy Mode Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determination by an autonomous driving system regarding the operation of vehicle devices may differ from user preferences, leading to suboptimal device operations.
Innovation Solution
A vehicle control interface box that stores correspondence information for determining device operation status based on user manipulation requests and autonomous system requests, prioritizing certain modes when conflicts arise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the autonomous driving system determines device operations independently, then automation level is improved, but device operation optimality deteriorates when it conflicts with user preferences
Solution Approach 1:
The vehicle control interface box serves as an intermediary between the autonomous driving system and the vehicle platform. It receives operation requests from both the autonomous driving system and user manipulation requests, stores correspondence information defining priority relationships, and determines final device operations by referencing this correspondence information. This mediator resolves conflicts between automated decisions and user preferences, ensuring optimal device operation while maintaining high automation levels.
2Device complexity
If uniform prioritization is applied to resolve conflicts between autonomous system and user requests, then system complexity is reduced, but device operation optimality deteriorates
Solution Approach 1:
Instead of applying uniform prioritization rules across all devices and situations, the system stores correspondence information that defines device-specific priority relationships. Each device or operation type can have its own customized priority rules stored in the vehicle control interface box, allowing optimal resolution tailored to each device's characteristics and operational context while keeping the overall system architecture simple.

AI summary
When a headlight driver input indicates an AUTO mode, a VCIB accepts a headlight mode request from an ADK. The VCIB identifies a current headlight driver input. The VCIB reads first correspondence information and checks the identified headlight driver input and the accepted headlight mode request against the first correspondence information to determine an illumination status of a headlight.
