Dynamic Driving Mode Assignment for In-Car Time Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of autonomous vehicles face challenges in utilizing time efficiently during varying driving modes, as the availability and suitability of activities differ significantly between manual, semi-autonomous, and autonomous driving levels, making it difficult to predict and utilize 'free' time effectively.
Innovation Solution
A system that assigns driving modes based on parameters like road type, traffic conditions, and personal preferences, and proposes relevant activities for each mode, allowing drivers to engage in suitable tasks during pilot-assisted and autonomous driving segments by indicating and executing different parts of the route and suggesting appropriate activities through interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle operates in manual driving mode, then the driver has full control and awareness, but the driver cannot engage in activities that require attention away from the road
Solution Approach 1:
The system dynamically transitions between manual and autonomous driving modes based on route segments, allowing the driver's role and available activities to change flexibly throughout the journey rather than remaining static
2Loss of time
If the vehicle operates in autonomous driving mode, then the driver can engage in various activities, but the vehicle can only operate on preapproved or certified roads
Solution Approach 1:
The route is divided into multiple segments with different automation levels assigned to each segment. This allows the system to provide autonomous driving capabilities on certified roads while maintaining manual control on non-certified roads, optimizing time utilization without sacrificing overall route flexibility
3Loss of time
If the system provides detailed activity suggestions for different driving modes, then time utilization is optimized, but the system complexity increases
Solution Approach 1:
The system pre-calculates and assigns driving modes to different route segments before the journey begins, based on certified road data. This preliminary action allows the system to provide activity suggestions without requiring complex real-time calculations during driving
