Autonomous Vehicle Confidence Score System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to enhance consumer confidence in autonomous vehicles by identifying safe areas for autonomous driving, as different levels of autonomy and varying driver experiences and environments affect trust and comfort levels.
Innovation Solution
A confidence enhancement system that uses a navigation unit, sensors, and an electronic control unit to determine a confidence score based on vehicle location, sensor data, and user profiles, adjusting autonomous driving levels and providing notifications to ensure safe operation, including communication with surrounding vehicles and infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous driving is activated in all areas, then productivity and transportation efficiency are improved, but safety and consumer confidence deteriorate due to varying driving conditions and driver comfort levels
Solution Approach 1:
The system applies local quality by evaluating autonomous driving safety on a location-specific basis rather than universally. The confidence score is calculated based on geographic location, environmental conditions, traffic patterns, and infrastructure quality at each specific area, allowing autonomous driving to be permitted in safe locations while restricted in unsafe ones.
Solution Approach 2:
The system implements dynamics by making the autonomous driving permission status changeable based on real-time conditions. The confidence score is dynamically updated as environmental conditions, traffic patterns, or infrastructure changes occur, allowing the system to adapt to varying driving conditions and update safety assessments accordingly.
2Ease of operation
If the autonomous driving system operates at high levels of autonomy, then ease of operation is improved, but consumer confidence and trust deteriorate due to lack of driver control and varying comfort levels
Solution Approach 1:
The system applies dynamics by allowing the level of autonomous driving to be adjusted dynamically based on driver comfort levels and environmental conditions. The system can transition between different levels of autonomy (from fully autonomous to driver-controlled) depending on the calculated confidence score and driver preferences, making the operation mode flexible rather than fixed.
Solution Approach 2:
The system implements feedback by continuously monitoring driver comfort levels, confidence scores, and operational conditions, then using this information to adjust the level of autonomous driving provided. The system learns from driver responses and environmental feedback to optimize the balance between automation and driver control.
