Vehicle Evacuation Control via V2V Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques, such as blinking hazard lamps and sounding a horn, are insufficient to alert drivers of surrounding vehicles to the danger posed by a vehicle with an incapacitated driver, potentially causing those vehicles to hinder the incapacitated vehicle's evacuation to a safe stop position.
Innovation Solution
A travelling support apparatus equipped with a communication section, state determination section, path setting section, information acquisition section, and evacuation control section, which communicates with surrounding vehicles to set an evacuation path and control the incapacitated vehicle's movement while informing others of its evacuation intentions, thereby preventing hindrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If hazard lamps are blinked and horn is sounded to alert surrounding vehicles, then the incapacitated vehicle's danger is communicated, but surrounding vehicles may still hinder the evacuation process
Solution Approach 1:
The system transmits evacuation information to surrounding vehicles and receives feedback about their status and position. This two-way communication allows the incapacitated vehicle to adjust its evacuation path based on real-time responses from surrounding vehicles, ensuring they understand the situation and will not hinder the evacuation process.
Solution Approach 2:
The communication device acts as an intermediary between the incapacitated vehicle and surrounding vehicles. It transmits structured evacuation information including the incapacitated vehicle's intentions and requests surrounding vehicles to cooperate, thereby mediating the interaction and ensuring smooth evacuation without direct human intervention.
2Reliability
If the incapacitated vehicle performs evacuation traveling to a stop position, then it can be brought to safety, but surrounding vehicles may obstruct the evacuation path
Solution Approach 1:
The system performs preliminary actions by transmitting evacuation information to surrounding vehicles before the evacuation process begins. This advance notification allows surrounding vehicles to prepare and adjust their positions, preventing potential obstructions before they occur and ensuring a clear evacuation path.
Solution Approach 2:
The system takes preliminary anti-action by requesting surrounding vehicles to cooperate and avoid obstructing the evacuation path before the evacuation begins. This proactive measure prevents harmful obstructions from occurring in the first place, rather than reacting to them after they happen.
3Ease of operation
If communication information is transmitted to surrounding vehicles, then cooperation can be obtained for smooth evacuation, but the system complexity increases
Solution Approach 1:
The communication device performs multiple functions: it transmits evacuation information, requests cooperation from surrounding vehicles, and receives their responses. By consolidating these functions into a single device, the system achieves smooth evacuation operations without proportionally increasing overall system complexity.
Solution Approach 2:
The communication system operates autonomously, automatically transmitting evacuation information and managing communication with surrounding vehicles without requiring manual intervention. This self-service capability simplifies operation while the automated nature keeps the system complexity manageable.

AI summary
A travelling support apparatus includes: a communication section that communicates with a vehicle around an own vehicle; a state determination section that determines whether a driver is capable of driving appropriately; a path setting section that sets an evacuation path for bringing the own vehicle to an emergency stop on the basis of a certain algorithm when the state determination section determines that the driver is incapable of driving appropriately; an information acquisition section that acquires various types of information required for execution of the algorithm; an evacuation control section that performs evacuation traveling to bring the own vehicle to the emergency stop along the evacuation path set by the path setting section; and an information transmitting section that transmits, to the vehicle around the own vehicle via the communication section, information indicating that the own vehicle performs the evacuation traveling.
