Disaster Vehicle Control for Evacuation Route Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems for ultra-compact mobility devices do not adequately address safety during disasters, potentially hindering evacuation efforts by obstructing evacuation routes or allowing vehicles to enter dangerous zones.
Innovation Solution
A vehicle control method that shifts unmanned vehicles to temporary refuge positions to avoid obstructing evacuees, while manned vehicles guide evacuees to safety using automatic or manual driving, ensuring both types of vehicles assist in safe evacuation without hindering passage or entry into dangerous areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle moves to a refuge place during disaster, then evacuation safety is improved, but the vehicle may hinder passage of evacuees or prevent entry into dangerous zones
Solution Approach 1:
The control device determines a refuge place in advance before the vehicle moves during disaster. By pre-calculating the optimal refuge position that avoids obstructing evacuation routes or dangerous zones, the system ensures the vehicle can take protective action without creating harmful effects during the emergency evacuation process.
2Loss of time
If the vehicle automatically moves to refuge place, then response time is improved, but control complexity increases
Solution Approach 1:
The control device autonomously determines the refuge place and controls the vehicle to move there without requiring external intervention. The system self-manages the disaster response process by automatically detecting disaster conditions, calculating appropriate refuge positions, and executing the movement, thereby reducing response time while keeping the control logic integrated within a single device.

AI summary
A vehicle control method according to an embodiment is a vehicle control method to be executed by a controller for controlling a vehicle that travels in an area, wherein the controller is configured to: in a case where detecting occurrence of a disaster and determining that nobody is riding on the vehicle, cause the vehicle to move to a refuge place, and the refuge place includes at least one of a place in which the vehicle having taken refuge hinders passage of an evacuee toward an outside of the evacuation route and a place in which the vehicle having taken refuge prevents an evacuee from entering a dangerous zone.
