Driver Feedback Control Using Driving Skill Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driver state estimation devices only provide warnings to drivers without actively improving their driving abilities, lacking a comprehensive evaluation and feedback mechanism to enhance driving skills.
Innovation Solution
A driving support device that includes a peripheral information acquisition unit, outside-world detection unit, driving status detection unit, driving evaluation unit, notification unit, and evaluation determination unit, which evaluates the driver's skills based on detected information and provides targeted feedback to improve driving abilities by notifying the driver of improvements or declines in their performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a driver state estimation device only notifies warnings to the driver, then the device complexity is reduced, but the driving ability improvement is insufficient
Solution Approach 1:
The system implements a feedback mechanism where the driving evaluation result is notified to the driver, and when the evaluation improves, specific feedback about the outside-world detection result or driving status is provided. This creates a closed-loop system that reinforces positive driving behaviors and promotes continuous improvement in driving ability.
2Reliability
If comprehensive driving evaluation and feedback mechanisms are implemented, then driving ability improvement is enhanced, but the device complexity increases
Solution Approach 1:
The system segments the driving evaluation process into distinct functional modules: outside-world detection unit for detecting targets, driving status detection unit for monitoring vehicle state, driving evaluation unit for assessing driving ability, and notification control unit for providing feedback. This modular segmentation reduces overall system complexity while enabling comprehensive evaluation.
Solution Approach 2:
The driving support device integrates multiple functions into a single system: it detects outside-world information, monitors driving status, evaluates driving ability, stores evaluation results, and provides targeted feedback. This multi-functionality approach consolidates what would otherwise require separate systems, managing complexity while achieving comprehensive driver improvement.
3Loss of information
If notification is provided only when driving evaluation improves, then information loss is reduced, but the feedback timeliness may be affected
Solution Approach 1:
The notification control unit automatically determines whether to provide feedback based on the driving evaluation result without requiring external intervention. When the evaluation improves, the system self-initiates the notification process, ensuring timely feedback while filtering out unnecessary information that would contribute to information loss.
