Vehicle Device Control Priority for User-Aware Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During autonomous driving, users may feel uncomfortable due to differences in the operation timing of vehicle devices such as headlights and windshield wipers between their personal preferences and the autonomous driving system's controls.
Innovation Solution
A vehicle platform that prioritizes user-set operation modes for devices like headlights, hazard lights, front windshield wipers, and rear windshield wipers over autonomous driving system requests, allowing users to maintain control over these settings even during autonomous driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the autonomous driving system controls various devices (headlights, windshield wipers, etc.) according to its own determination, then the autonomous driving function is improved, but user comfort deteriorates due to differences in operation timing from user preferences
Solution Approach 1:
The system dynamically switches between autonomous driving system control and user control for various devices based on real-time detection of user operations. When user operations are detected, the system transitions to user priority mode; when no user operations are detected, it operates in autonomous system priority mode. This dynamic adaptation resolves the contradiction by allowing the system to be fully automated when users are not interacting, while seamlessly switching to user control when needed, thus maintaining both high automation extent and user comfort.
2Ease of operation
If the vehicle prioritizes user operations for device control, then user comfort is improved, but the autonomous driving system's ability to control devices according to its determination is reduced
Solution Approach 1:
The system applies user priority control selectively and partially - only when user operations are actually detected. For all other periods without user interaction, the autonomous driving system maintains full control. This partial application of user priority resolves the contradiction by ensuring user comfort is improved precisely when users interact with the system, while the autonomous driving system's control capability remains intact during non-interaction periods.
3Extent of automation
If the autonomous driving system determines operation timing for various devices, then system automation is improved, but adaptability to individual user preferences deteriorates
Solution Approach 1:
The system continuously monitors and detects user operations on various devices, using this feedback to dynamically adjust control priority. When user operations are detected, the system switches to user priority mode, adapting to individual user preferences in real-time. This feedback mechanism resolves the contradiction by allowing the system to maintain high automation while simultaneously adapting to user preferences through real-time detection and response to user interactions.

AI summary
When a first driver setting mode indicates an “OFF mode” or an “AUTO mode,” a VP accepts a light operation mode request from an ADK. When an operation is performed by a user, the VP changes an operation mode of a headlight in accordance with the operation by the user. When the operation by the user has not been performed, the VP changes the operation mode of the headlight in accordance with the light operation mode request.
