Vehicle Platoon Exit Control Using Adjacent Lane Time Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle platooning methods do not provide a safe and efficient process for a following vehicle to leave a platoon, potentially leading to collisions with adjacent vehicles and traffic congestion.
Innovation Solution
A method and device that assist a vehicle in leaving a platoon by determining approval based on the expected time for an adjacent vehicle to reach a parallel position, allowing safe and quick overtaking through an adjacent lane, using a communication module and controller to receive and transmit leave-request and leave-approval messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a following vehicle leaves a vehicle platoon by moving to an adjacent lane, then the vehicle can exit the platoon, but it may collide with a vehicle adjacent to the platoon
Solution Approach 1:
The control device determines whether to approve the lane change before the vehicle actually changes lanes. It calculates the expected time for the vehicle to reach a position parallel to the platoon and compares this with the time for adjacent vehicles to reach the same position, making a safety determination in advance to prevent collisions
Solution Approach 2:
The control device continuously monitors the positions and speeds of the leaving vehicle and adjacent vehicles, calculating expected arrival times at parallel positions. This feedback mechanism allows real-time assessment of collision risk and dynamic adjustment of lane change approval decisions
2Ease of operation
If a following vehicle leaves a vehicle platoon without proper coordination, then the vehicle can exit independently, but it may cause traffic congestion by traveling inefficiently
Solution Approach 1:
The control device communicates with the leaving vehicle through V2V communication, providing feedback on whether the lane change is approved. This coordination ensures that independent vehicles leave the platoon in an organized manner that maintains overall traffic flow efficiency and prevents congestion

AI summary
A device and a method for controlling vehicle platooning are disclosed.The method of controlling a vehicle for assisting leaving from a vehicle platoon. The method comprises receiving a leave-request message including an overtaking intention from a first vehicle included in the vehicle platoon. The method comprises determining approval for the first vehicle to leave based on an expected time required for another vehicle in an adjacent lane to reach a position parallel to a position of the first vehicle. The method comprises transmitting a leave-approval message to the first vehicle.
