Vehicle Communication Device Coordinating Entry Times
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to manage the simultaneous entry of multiple vehicles into a predetermined area effectively, minimizing bottlenecks and optimizing communication to prevent collisions and enhance safety and convenience, particularly in scenarios where vehicles enter at the same time, which existing systems struggle to address efficiently.
Innovation Solution
A communication device equipped with a processor and communication unit that receives path information from multiple vehicles, determines the likelihood of entry into a shared area, and transmits control messages to adjust vehicle entry times, selecting vehicles capable of autonomous control or better communication quality to optimize traffic flow and prevent bottlenecks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple vehicles are allowed to enter a predetermined area simultaneously, then traffic flow efficiency is improved, but collision risk and safety issues worsen
Solution Approach 1:
The communication device performs preliminary determination of vehicle entry possibilities before vehicles actually enter the predetermined area. By calculating the possibility of each vehicle entering the area in advance and comparing it with a reference value, the system proactively identifies potential conflicts and transmits control messages to adjust entry timing, thereby preventing collisions before they occur while maintaining efficient traffic flow
Solution Approach 2:
The system establishes a feedback loop where the communication device continuously receives path information from multiple vehicles, determines entry possibilities, transmits control messages when conflicts are detected, and monitors subsequent vehicle movements. This closed-loop feedback mechanism enables real-time coordination between vehicles, allowing simultaneous entry when safe while preventing collisions when risks are identified
2Reliability
If control messages are transmitted to all vehicles, then collision prevention is improved, but communication overhead and system complexity worsen
Solution Approach 1:
The communication device applies local quality by selectively transmitting control messages only to specific vehicles based on individual entry possibility calculations. Instead of uniformly controlling all vehicles, the system identifies which vehicles have entry possibilities exceeding the reference value and targets control messages only to those vehicles, thereby reducing communication overhead while maintaining effective collision prevention
Solution Approach 2:
The system changes the parameter of control message transmission from a static all-or-nothing approach to a dynamic selective approach. By continuously evaluating entry possibility parameters for each vehicle and adjusting transmission decisions based on these changing parameters, the system optimizes the balance between collision prevention and communication efficiency

AI summary
A communication device includes a communication unit configured to receive first path information from a first vehicle and to receive second path information from a second vehicle, and a processor configured to determine a possibility of the first and second vehicles entering a predetermined area based on the first and second path information, and based on the possibility being greater than a reference, transmit a message for controlling at least one of the first vehicle or the second vehicle through the communication unit to allow the first and second vehicles to enter the predetermined area at different time points.
