Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems for autonomous vehicles lack adaptability and do not account for unique capabilities such as hands-free time or sleep time, limiting their routing options and flexibility compared to non-autonomous vehicles.
Innovation Solution
A navigation apparatus and method for autonomous vehicles that receives and displays routes with characteristics like hands-free and sleep time, dividing routes into segments based on these characteristics and highlighting them for user selection, allowing for optimized route planning considering driver states and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional navigation systems are used for autonomous vehicles, then basic routing functionality is provided, but adaptability to autonomous vehicle capabilities (hands-free time, sleep time) is lost
Solution Approach 1:
The patent segments the route into multiple route segments based on autonomous driving characteristics. Each segment is evaluated for its suitability for hands-free driving, sleep time, and other autonomous capabilities. This segmentation allows the system to provide detailed, capability-specific routing information rather than treating the entire route as a single unit.
Solution Approach 2:
The navigation system dynamically adjusts route recommendations based on real-time driver state and vehicle capabilities. The system can modify the suggested route during traversal based on changing conditions, such as transitioning from a segment suitable for hands-free driving to one requiring driver attention. This dynamic adaptation enhances both adaptability and routing reliability.
2Productivity
If conventional navigation systems select routes based on traditional factors (travel distance, travel time), then basic routing efficiency is achieved, but optimization for autonomous-specific factors (hands-free time, sleep time) is lost
Solution Approach 1:
The patent introduces new evaluation parameters specific to autonomous vehicle capabilities, including hands-free driving time, sleep time, and other autonomous operation metrics. These parameters replace or supplement traditional routing factors like distance and time, enabling the system to optimize routes based on autonomous-specific productivity metrics while maintaining adaptability to different vehicle configurations.
3Ease of operation
If detailed route characteristics and segmentation are provided, then user selection flexibility is improved, but information processing complexity increases
Solution Approach 1:
The patent extracts and highlights only the most relevant route characteristics and segments that match the driver's current state and preferences. Rather than presenting all possible route attributes simultaneously, the system selectively displays information based on what is most useful for the current decision context, reducing information overload while maintaining user flexibility.
Solution Approach 2:
The system acts as an intermediary between the complex route data and the user by processing and filtering information before presentation. It translates detailed route characteristics into user-friendly recommendations, managing the complexity internally while presenting simplified, actionable options to the user.
