Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional route search methods fail to present an ecological route that is easily accepted by users, as they often suggest routes significantly different from the user's usual travel path, making it difficult for users to accept the proposed switch to an electric vehicle.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a route search is performed based solely on link cost to find the optimal route, then energy consumption is minimized, but the route may be completely different from the user's usual travel path, making it difficult for the user to accept
Solution Approach 1:
The patent changes the route search parameters by introducing a dual-cost evaluation system. Instead of using only link cost (energy consumption), it combines link cost with identity cost (similarity to usual route) to create a comprehensive evaluation index. This parameter change allows the system to find routes that balance energy efficiency with user acceptance, resolving the contradiction between minimizing energy consumption and maintaining user acceptance.
Solution Approach 2:
The patent applies beforehand cushioning by pre-calculating and storing the usual travel routes and their characteristics before performing the optimal route search. This pre-prepared information serves as a reference baseline that cushions against the potential user rejection of completely new routes. The system uses this pre-established data to ensure the recommended route maintains sufficient similarity to the user's accustomed path while still achieving energy savings.
2Loss of energy
If a route completely different from the user's usual route is presented as optimal, then energy consumption may be reduced, but the user finds it difficult to accept as a future self-traveling route
Solution Approach 1:
The patent transforms the route evaluation from a single-parameter (link cost) system to a multi-parameter system that includes both energy consumption and route identity. By changing the evaluation parameters to include similarity metrics compared to usual routes, the system can identify routes that achieve energy savings without sacrificing adaptability to user preferences and habits.
Solution Approach 2:
The patent introduces route identity (similarity to usual route) as an intermediary factor between energy consumption and user acceptance. This intermediary parameter acts as a bridge, allowing the system to translate energy-efficient routes into user-acceptable recommendations by ensuring they maintain sufficient resemblance to the user's established travel patterns.
3Ease of operation
If the system recommends a route with high identity to the user's usual route, then user acceptance improves, but energy consumption may not be minimized
Solution Approach 1:
The patent changes the optimization objective from minimizing only energy consumption to minimizing a composite cost function that includes both energy consumption and route identity. This parameter transformation enables the system to find routes that achieve an optimal balance between user acceptance and energy efficiency, rather than prioritizing one factor at the expense of the other.

AI summary
An information processing device (100) according to the present disclosure includes: an acquisition unit (131) configured to acquire a history of a moving route in which a first moving object has moved from a departure point to a destination; and an output control unit (134) configured to cause a route searched from among candidate routes from the departure point to the destination to be output as a proposed route for moving by a second moving object different from the first moving object. In addition, the output control unit (134) causes the route searched from among the candidate routes to be output as the proposed route on condition that the route has higher identity with the moving route and an energy consumption amount is smaller than that in a case of moving the moving route by the second moving object.
