Vehicle Device Control for User Override in Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During autonomous driving, users may feel uncomfortable due to differences in the operation modes of vehicle devices such as headlights, hazard lights, and windshield wipers, which can be set differently by the autonomous driving system and the user.
Innovation Solution
A vehicle platform that prioritizes the user's operation mode settings for headlights, hazard lights, and windshield wipers over requests from the autonomous driving system, allowing users to set these modes manually, especially in predefined modes like OFF or AUTO, ensuring consistency with their preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the autonomous driving system controls various devices (headlights, hazard lights, windshield wipers) according to its own determination, then the autonomous driving function is improved, but the user comfort deteriorates due to difference in determination between the system and user preferences
Solution Approach 1:
The patent inverts the traditional control hierarchy by allowing user operations to override autonomous driving system commands for various vehicle devices. When the user operates the operation apparatus (e.g., steering wheel, pedals), the system switches from autonomous control to user manual control for affected devices, thereby resolving the contradiction between automation and user comfort.
2Ease of operation
If the vehicle prioritizes user operation mode settings over autonomous driving system requests, then user comfort is improved, but the autonomous driving automation level deteriorates
Solution Approach 1:
The patent implements dynamic control mode switching where the vehicle can transition between autonomous driving mode and user manual control mode based on user operations. The system dynamically adjusts which devices are under autonomous control versus user control, allowing flexible adaptation to user needs while maintaining high automation capability when desired.

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.
