EV Route Recalculation Using Pre-Departure Vehicle Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems for electric vehicles do not account for changes in vehicle status after the travel route has been calculated, potentially leading to inadequate routes based on the vehicle's current condition.
Innovation Solution
An information processing system that continuously updates the travel route based on real-time vehicle information, allowing for a second travel route calculation before the vehicle starts traveling, ensuring the route reflects the most recent vehicle status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the travel route is calculated at the timing when the user inputs a waypoint and destination, then the route calculation is performed with available information at that time, but the route may not reflect the most recent vehicle status if the status changes after calculation
Solution Approach 1:
The system performs a preliminary first route calculation when the user inputs destination information, then conducts a second route calculation before the vehicle actually starts traveling. This preliminary action ensures the route reflects the most recent vehicle status while still allowing time for recalculation, resolving the contradiction between route accuracy and calculation timing.
2Reliability
If the travel route is recalculated based on real-time vehicle information, then the route reflects the most recent vehicle status, but this requires additional processing time and computational resources
Solution Approach 1:
The system performs the second route calculation based on real-time vehicle information before the vehicle starts traveling. This preliminary recalculation ensures route accuracy reflects the most recent vehicle status without requiring complex real-time adjustments during travel, balancing reliability with processing complexity.
Solution Approach 2:
The navigation device automatically performs the second route calculation using acquired vehicle information without requiring additional user input or manual intervention. The system serves itself by detecting vehicle status changes and autonomously recalculating the route, reducing processing complexity while maintaining high route accuracy.
3Ease of operation
If the system waits for the vehicle to start traveling before providing the route, then the route is final and stable, but the vehicle cannot benefit from the most recent vehicle status information
Solution Approach 1:
The system completes the second route calculation before the vehicle starts traveling, providing the most recent and suitable route information in advance. This allows the vehicle to benefit from updated vehicle status information while still providing a stable, finalized route for user guidance, improving both convenience and reliability.

AI summary
An information processing method, an information processing system, an information processing device, and an information terminal of the present invention, accepts a destination for the vehicle, then searches for the travel route to the destination and sets as a first travel route, and sets a travel start time to start traveling on the first travel route. Then, vehicle information is acquired for the vehicle in advance of the travel start time by a prescribed time after the setting of the first travel route; and a travel route to the destination is searched again and a second travel route is set based on the vehicle information.
