V2V Queue Notification for Driver Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face significant delays when waiting in a queue of vehicles, as they often cannot see or are not aware of the movement of vehicles ahead due to obstacles or inattention, leading to a large time-gap before each vehicle starts moving.
Innovation Solution
A Vehicle-to-Vehicle (V2V) communication system, including a DSRC radio, camera, and processing unit, provides a preliminary notification to the driver of a host vehicle when remote vehicles in front are likely to start moving by determining the movement of specified vehicles through basic safety messages and controlling a notifying device to alert the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If drivers wait in a queue without notification, then they can maintain normal stopping behavior, but they experience large delays before each vehicle starts moving
Solution Approach 1:
The system performs preliminary action by notifying the driver in advance that remote vehicles are likely to start moving. The controller determines when remote vehicles (second or further vehicles in the queue) are about to move and activates the notifying device before the driver would naturally observe the movement, allowing the driver to prepare for upcoming traffic flow changes.
Solution Approach 2:
The notifying device acts as an intermediary between the remote vehicles and the driver. Instead of the driver directly observing remote vehicle movements through the preceding vehicle (which may be blocked), the notifying device mediates this information transfer, converting remote vehicle movement data into driver-perceptible notifications.
2Loss of information
If the preceding vehicle blocks the view of remote vehicles, then the driver cannot see the movement of vehicles ahead, but the driver should still be aware of traffic flow changes
Solution Approach 1:
The notifying device serves as an intermediary that bypasses the visual obstruction caused by the preceding vehicle. It receives movement information from remote vehicles through V2V communication and directly notifies the driver, eliminating the need for the driver to visually observe remote vehicles through the blocked view.
Solution Approach 2:
The system replaces the mechanical visual observation system (driver's eyes viewing remote vehicles directly) with an electronic information transmission system (V2V communication and notifying device). This substitution allows the driver to receive accurate movement information without relying on visual line-of-sight that is blocked by the preceding vehicle.
3Loss of information
If drivers are not paying attention to traffic, then they miss cues about vehicle movement ahead, but continuous monitoring increases cognitive load
Solution Approach 1:
The system applies preliminary action by notifying the driver before traffic flow changes occur. Instead of requiring continuous driver attention to detect movement cues, the system proactively provides information about upcoming vehicle movements, allowing drivers to maintain normal attention levels while still receiving critical traffic flow information.
Solution Approach 2:
The notification system operates autonomously by automatically determining when remote vehicles are likely to move and activating notifications without driver intervention. The controller continuously monitors remote vehicle status and independently decides when notification is needed, reducing the cognitive burden on the driver while maintaining effective communication.

AI summary
The present disclosure provides a system for providing a driver of a host vehicle being stopped with a preliminary notification that remote vehicles forming a queue in front of the host vehicle are likely to start moving. The system includes a receiver, a notifying device, a determiner, and a controller. The receiver is configured to receive messages from the remote vehicles through Vehicle-to-Vehicle (V2V) communications. The notifying device is configured to provide the driver with the preliminary notification. The determiner is configured to determine whether a specified vehicle among the remote vehicles other than a preceding vehicle directly ahead of the specified vehicle starts moving based on the messages sent from the specified vehicle. The controller is configured to control the notifying device to provide the preliminary notification when the determiner determines that the specified vehicle starts moving.
