Vehicle Route Planning Using Other-Vehicle Travel Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems do not optimize travel routes based on various factors such as weather, road surface, and parking information, leading to reduced comfort and safety for vehicle occupants.
Innovation Solution
An information processing device that acquires travel information from another vehicle that has traveled on a candidate route and uses this data to decide an optimal route for the destination, considering factors like weather, road conditions, and parking information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a navigation system provides a travel route based on basic routing algorithms, then the route can be calculated quickly, but the route is not optimized for comfort and safety based on weather, road surface, and other dynamic conditions
Solution Approach 1:
The system performs preliminary actions by having other vehicles collect and transmit travel information (weather, road surface, parking) along candidate routes before the user vehicle needs to make routing decisions. This advance data collection enables optimized route selection without real-time delays
Solution Approach 2:
The navigation system uses other vehicles as intermediaries to gather environmental data along potential routes. These vehicles act as mobile sensors that collect information about weather conditions, road surface states, and parking availability, which is then transmitted to the user vehicle for route optimization
2Measurement precision
If the system acquires travel information from other vehicles to optimize routes, then comfort and safety improve, but information accuracy may be affected by data timing and source reliability
Solution Approach 1:
The system implements feedback mechanisms where other vehicles continuously transmit their current position, collected travel information, and status data back to the navigation system. This ongoing feedback loop allows the system to track data freshness and adjust route recommendations based on the most recent information available
Solution Approach 2:
The navigation system dynamically adjusts route recommendations based on the timing and source of travel information. It can weight recent data more heavily, adjust for vehicle-specific observation conditions, and update routes in real-time as new information becomes available from moving vehicles

AI summary
An information processing device that provides a travel route to a destination to an occupant of a vehicle includes a controller. The controller is configured to acquire travel information obtained by another vehicle that travels on a candidate route to the destination set by the occupant from a second point in time prior to a first point in time when the destination is set to the first point in time in relation to traveling of the other vehicle, and to decide the travel route optimal for driving of the vehicle to the destination based on the acquired travel information.
