Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles exhibit varying driving styles due to differences in control system programming and sensing capabilities, leading to unpredictable behavior that can cause accidents and unpleasant experiences for nearby drivers.
Innovation Solution
A system that collects driving characteristics and occupant feedback using sensors and user interfaces to characterize the driving style of autonomous vehicles, which can be evaluated onboard or offboard to identify patterns and share this information with nearby vehicles for enhancing safety and experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomous vehicles use different control system programming and sensing capabilities, then each vehicle can be optimized for its specific function, but driving style variations become unpredictable and lead to safety issues
Solution Approach 1:
The system collects driving characteristic data from sensors and occupant feedback through user interfaces, then uses this feedback to characterize and classify driving styles. This feedback loop enables the system to adapt to individual vehicle behaviors while maintaining overall safety through centralized monitoring and classification of driving patterns.
Solution Approach 2:
A centralized server acts as an intermediary between autonomous vehicles with different control systems. The server receives driving characteristic data from various vehicles, processes this information to characterize driving styles, and provides a standardized framework that mediates between diverse control system programming, ensuring predictable and safe interactions.
2Reliability
If driving style information is collected and shared with nearby vehicles, then safety and driving experience are improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system segments driving style characterization into distinct components: sensor data collection, occupant feedback collection, pattern evaluation, and style classification. This segmentation allows each component to be independently optimized and managed, reducing overall system complexity while maintaining comprehensive safety monitoring.
Solution Approach 2:
A centralized server serves as an intermediary that handles the complex data processing and driving style characterization. This mediator absorbs the computational complexity, allowing individual vehicles to maintain simpler onboard systems while still benefiting from comprehensive driving style analysis and safety improvements.
