Route Search Device for Multi-Modal Transport via Automatic Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route search devices do not account for routes where the user moves by transportation means other than a vehicle from a departure place to a parking lot, leading to inconvenient situations.
Innovation Solution
An information processing device that acquires current vehicle position information and searches for routes from the departure place to a destination, allowing users to save time and labor by setting the vehicle's position as a via point, and also searching for routes without passing through the vehicle's current position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the route search device only searches for routes using vehicle from departure place to destination, then the route search is simple, but the user convenience deteriorates when the user needs to use transportation means other than vehicle
Solution Approach 1:
The route search is divided into multiple segments: departure place to parking lot (using transportation means other than vehicle), parking lot to destination (using vehicle), and return routes. This segmentation allows the system to handle different transportation modes separately while maintaining overall simplicity through modular processing
Solution Approach 2:
The route search device is enhanced to handle multiple transportation modes universally - both vehicle-based and non-vehicle-based transportation means can be used for route search. The system automatically determines which mode to use based on user input or default settings, providing multi-functional capability without significantly increasing complexity
2Measurement precision
If the user manually sets the vehicle position as a via point, then the route search precision is improved, but the user labor and time increase
Solution Approach 1:
The system automatically acquires the vehicle's current position information through GPS or other positioning technologies without requiring manual input from the user. The route search device autonomously uses this position data as the via point, making the system self-serve the position acquisition function and eliminating user labor while maintaining route precision
Solution Approach 2:
The system performs preliminary acquisition of vehicle position information before the route search is initiated. By pre-obtaining the current position data through automatic positioning, the system prepares the necessary parameters for accurate route calculation without requiring the user to manually input position information at the time of route search

AI summary
In an information processing device, an acquisition unit acquires current position information of a vehicle. A route search unit searches for a route from a departure place via the current position of the vehicle to a destination based on the current position information of the vehicle acquired by the acquisition unit.
