V2X Virtual Vehicle Path Reservation for Sequential Lane Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles struggle to sequentially change driving paths while preventing collisions with neighboring vehicles, especially when they have the same or crossing paths, and existing ADAS systems are inadequate for reliably avoiding such collisions.
Innovation Solution
A method using V2X multi-virtual vehicle messages to reserve sequential driving path positions, broadcast these changes to neighboring vehicles, and utilize ADAS systems to adjust vehicle states based on received messages, including displaying path changes on the dashboard or navigation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle uses manual path selection based on road condition information, then the driver can control the driving path, but the vehicle cannot sequentially change driving path while preventing collision with neighboring vehicles
Solution Approach 1:
The vehicle transmits a first message reserving a first path change position before actually changing path, and transmits a second message reserving a second path change position before the second path change. This preliminary reservation of path positions prevents neighboring vehicles from attempting simultaneous path changes that would cause collisions.
Solution Approach 2:
The system uses V2X communication to exchange path reservation information between vehicles. When a vehicle receives a path reservation message from another vehicle, it adjusts its own path changing timing accordingly, creating a feedback loop that coordinates multiple vehicles and prevents collisions.
2Reliability
If a vehicle uses ADAS to avoid collision with neighboring vehicles, then collision avoidance capability is provided, but it cannot reliably avoid collision with neighboring vehicles changing driving path
Solution Approach 1:
Instead of reacting to neighboring vehicles' path changes after they occur, the system preliminarily reserves path positions by transmitting messages before actual path changes. This allows the vehicle to proactively coordinate with neighboring vehicles and prevent collisions before they become imminent threats.
Solution Approach 2:
The V2X communication system acts as an intermediary between vehicles, allowing them to exchange path reservation information and coordinate their actions. This intermediary communication layer enables reliable collision avoidance by facilitating awareness and coordination between independently operating vehicles.

AI summary
Disclosed herein is a method for transmitting a signal by a vehicle in a wireless communication system. The method may include: obtaining information on a predetermined position on a second driving path adjacent to a first driving path based on the vehicle driving on the first driving path; transmitting a first message which includes virtual vehicle information corresponding to the vehicle on the second driving path and reserves the predetermined position on the second driving path; obtaining information on a predetermined position on a third driving path adjacent to the second driving path based on the predetermined position on the second driving path being successfully reserved; and transmitting a second message which includes virtual vehicle information corresponding to the vehicle on the third driving path and reserves the predetermined position on the third driving path.
