Automated Driving Preference Feedback for Override-Based Comfort Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving support apparatuses do not account for user preferences in automatic driving control, leading to discomfort when the automatic driving control does not match the user's original preferences.
Innovation Solution
A driving support apparatus that includes a sensor to acquire environmental information and a controller to execute a learning control for learning vehicle behaviors during manual driving. The controller starts behavior control based on learned behaviors at a user-preference specified start point and suggests preference changes if manual overrides occur not caused by external factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the automatic driving control executes based on pre-designated user preference, then the user preference is respected, but the user may feel uncomfortable when the designated preference differs from the original preference
Solution Approach 1:
The system monitors manual operations during automatic driving control and uses this feedback to detect when the designated preference differs from the user's original preference. When a manual operation occurs that is not caused by external environment, the system infers a preference mismatch and provides feedback to the user to change the designated preference, thereby resolving the contradiction between respecting user preferences and ensuring user comfort.
Solution Approach 2:
The system automatically detects preference mismatches by monitoring manual operations and autonomously determines when the designated preference differs from the original preference. The system then prompts the user to adjust the preference setting, enabling the system to self-correct without external intervention while maintaining user comfort.
2Reliability
If the system monitors manual operations to detect preference mismatches, then the user comfort is improved, but the device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it executes automatic driving control based on learned behaviors, monitors manual operations, determines whether operations are caused by external environment, detects preference mismatches, and prompts users to change settings. By consolidating these diverse functions into a single control unit, the system achieves improved user comfort without proportionally increasing overall device complexity.

AI summary
A driving support apparatus executes an automatic driving control for controlling a behavior of a vehicle to reproduce a learned behavior. The driving support apparatus starts a behavior control for controlling the behavior of the vehicle based on the learned behavior, when the vehicle arrives at a control start point during the automatic driving control. The control start point is specified based on a start point at which the manual operation was performed and a preference of a user. The driving support apparatus controls the behavior of the vehicle based on the manual operation and determines whether or not the manual operation is caused by the external environment, when the manual operation performed during the automatic driving control satisfies an override condition. When the manual operation is not caused by the external environment, the driving support apparatus suggests to the user to change the preference.
