Driving Assist Route Optimization Using Use Possibility Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle navigation systems do not adequately consider road environments when recommending routes, making it difficult for drivers to utilize driving assist functions like preceding vehicle follow-up and lane keeping, especially on roads with heavy traffic or poorly maintained lanes, which limits the effectiveness and safety of these features.
Innovation Solution
An information processing device and method that acquires and calculates the use possibility of driving assist functions based on vehicle data, including use rates and driver operation, to recommend routes optimized for the use of these features, by transmitting this information to vehicles equipped with driving assist systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If navigation systems set driving routes based on distance and time, then route efficiency is improved, but driving assist function usability deteriorates
Solution Approach 1:
The patent changes the routing parameter from traditional distance/time-based optimization to driving assist function usability-based optimization. The system calculates a 'use possibility' parameter that represents how suitable a route is for using driving assist functions, and uses this as the primary criterion for route selection instead of conventional efficiency metrics.
Solution Approach 2:
The patent introduces an intermediary information processing device that collects actual driving data from multiple vehicles, calculates driving assist function usability for different routes, and provides this information to navigation systems. This intermediary layer bridges the gap between raw driving data and route optimization decisions.
2Device complexity
If driving routes are selected without considering road environment, then route selection simplicity is improved, but driving assist function effectiveness deteriorates
Solution Approach 1:
The system performs preliminary analysis of road environments and driving assist function usability before route selection. By pre-calculating the 'use possibility' of driving assist functions for various routes based on historical and real-time data, the system prepares optimization criteria in advance, maintaining simplicity while improving effectiveness.
Solution Approach 2:
The patent implements a feedback mechanism where actual driving data from vehicles is continuously collected and used to update the calculation of driving assist function usability. This feedback loop allows the system to learn from real-world performance and improve route recommendations over time without increasing complexity.
3Adaptability or versatility
If driving assist functions are used on unsuitable roads, then function availability is improved, but safety and comfort deteriorate
Solution Approach 1:
The patent applies local quality by evaluating driving assist function suitability for specific local road conditions rather than uniformly across all routes. The system calculates 'use possibility' based on local characteristics such as traffic density, road geometry, and lane conditions, allowing driving assist functions to be recommended only for appropriate local segments of a route.

AI summary
An information processing device includes circuitry configured to: acquire, from vehicles each of which has a driving assist function, a use information of the driving assist function of each of the vehicles that are traveling; calculate an information indicating a use possibility of the driving assist function on the basis of the use information; and transmit the information indicating the use possibility to a given vehicle having the driving assist function in a manner that the given vehicle uses the information indicating the use possibility to conduct a route search.
