Route Segmentation for Autonomous Vehicle Dispatch Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic driving vehicles face challenges in accurately acquiring peripheral information in certain environments, leading to uncertainties in route planning and service availability for users, as existing systems do not clearly differentiate permissible and non-permissible regions for vehicle operation.
Innovation Solution
A route information decision device and system that searches for routes and distinguishes permissible and non-permissible regions based on driving environment information, allowing users to plan their journey by identifying sections where automatic driving vehicles can be used and providing alternative routes through manual driving vehicles when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system provides route information for automatic driving vehicles, then users can plan their movement, but the service cannot be provided in non-permissible regions where the vehicle is not permitted to be dispatched
Solution Approach 1:
The route is segmented into permissible route parts (contained in permissible regions where the vehicle is permitted to be dispatched) and non-permissible route parts (contained in non-permissible regions where the vehicle is not permitted to be dispatched). This segmentation allows the system to provide reliable service information by clearly identifying which portions of the route can be served by automatic driving vehicles.
Solution Approach 2:
Different regions along the route are assigned different qualities: permissible regions where the automatic driving vehicle can operate and non-permissible regions where it cannot. This local differentiation enables the system to provide adapted service information for each region, maintaining reliability while preserving adaptability across diverse route conditions.
2Loss of information
If the system clearly marks permissible and non-permissible regions, then users can make informed movement plans, but the route information becomes more complex
Solution Approach 1:
The route information is segmented into distinct permissible and non-permissible parts, allowing the system to provide clear, differentiated information without overwhelming complexity. Each segment is clearly marked with its operational status, enabling users to make informed decisions.
Solution Approach 2:
The system provides partial route information (only the necessary distinction between permissible and non-permissible parts) rather than exhaustive details about every aspect of the route. This partial information approach maintains clarity while avoiding excessive complexity.

AI summary
A route information decision device includes: a route search unit that searches for a route along which a user moves from a first spot to a second spot; a partial route decision unit that decides a permissible route part of the route and a non-permissible route part of the route, the permissible route part being contained in a permissible region where a vehicle is permitted to be dispatched to the user, the non-permissible route part being contained in a non-permissible region where the vehicle is not permitted to be dispatched to the user, the vehicle being a vehicle for which an automatic driving control is performed.
