Autonomous Vehicle Travel Control Under Natural Disaster Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving vehicle systems lack the capability to respond appropriately to natural phenomena that could cause disasters, such as heavy rain, snow, floods, earthquakes, or tsunamis, potentially putting users at risk by continuing travel without intervention.
Innovation Solution
An autonomous driving vehicle equipped with an information acquisition device and a vehicle travel control device that recognizes alarming phenomena, determines whether to halt or alter its travel plan, and executes an emergency plan based on the type and severity of the event, including bypassing or evacuating from hazards and unlocking doors for user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous driving vehicle continues autonomous travel toward the destination without response to natural phenomena, then the vehicle maintains its original travel plan and operational simplicity, but user safety deteriorates when disasters occur
Solution Approach 1:
The vehicle travel control device performs alarming phenomenon recognition processing to identify natural disasters before they affect the vehicle's travel. By detecting earthquakes, heavy rains, floods, and other alarming phenomena in advance through sensor data and delivery information, the system can proactively adjust the travel plan to avoid hazardous areas, thereby improving user safety without requiring complex real-time response mechanisms during the disaster event
Solution Approach 2:
The system continuously receives delivery information from management servers about natural phenomena in various areas and feeds this information back to the vehicle travel control device. This feedback mechanism allows the vehicle to monitor changing environmental conditions and dynamically adjust its travel plan based on real-time disaster information, maintaining reliability while using a relatively simple control architecture
2Reliability
If the vehicle halts travel control to respond to alarming phenomena, then user safety improves, but travel time and productivity deteriorate
Solution Approach 1:
The vehicle travel control device dynamically adjusts the travel plan based on the type and severity of alarming phenomena. For earthquakes and tsunamis, the vehicle halts at the current location and unlocks doors for user safety. For heavy rains and floods, the vehicle actively reroutes to bypass hazardous areas while continuing travel. This dynamic response strategy ensures user safety is prioritized while minimizing unnecessary travel time losses
Solution Approach 2:
The system changes operational parameters based on the type of alarming phenomenon detected. When earthquakes or tsunamis are detected, the vehicle changes from moving state to stopped state and from locked door state to unlocked door state. When heavy rains or floods are detected, the vehicle changes the travel route parameter to bypass hazardous areas. These parameter changes allow the system to respond appropriately to different disaster scenarios while optimizing travel time
3Adaptability or versatility
If the vehicle implements comprehensive emergency control processing for all types of alarming phenomena, then user safety and adaptability improve, but device complexity increases
Solution Approach 1:
The vehicle travel control device implements different local response strategies for different types of alarming phenomena. For earthquakes and tsunamis, the vehicle halts at the current location and unlocks doors. For heavy rains and floods on the travel route, the vehicle bypasses hazardous areas. For heavy rains and floods at the current location, the vehicle evacuates to safe areas. This localized quality approach allows the system to be highly adaptable to different disaster types while maintaining a relatively simple control structure by using clear if-then logic for each scenario

AI summary
An autonomous driving vehicle provides a driverless transportation service for a user. An alarming phenomenon is a natural phenomenon that potentially causes a disaster. The autonomous driving vehicle recognizes, based on driving environment information, the alarming phenomenon at a current location of the autonomous driving vehicle or on a planned travel route from the current location to a destination. When recognizing the alarming phenomenon, the autonomous driving vehicle determines whether to continue or halt vehicle travel control in accordance with a current travel plan. When determining to halt the vehicle travel control in accordance with the current travel plan, the autonomous driving vehicle sets an emergency plan depending on a type of the alarming phenomenon and controls the autonomous driving vehicle in accordance with the emergency plan.
