Vehicle Control Device Passing Vehicle Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On bidirectional two-lane roads, passing vehicles can be hidden behind target vehicles, making it difficult for oncoming vehicles to recognize them, which can lead to head-on collisions, and existing solutions are not easily applicable to vehicles with human drivers due to assumptions based on controlled vehicle environments.
Innovation Solution
A vehicle control device and method that uses radio communication to notify oncoming vehicles of passing vehicles by generating and transmitting position data, determining passing and oncoming vehicles based on received communication data, and providing driving support to prevent collisions, while minimizing radio communication congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio communication transmission output is increased to ensure sufficient communicable area between passing vehicle and oncoming vehicle, then communication reliability is improved, but radio communication congestion occurs
Solution Approach 1:
The patent introduces a second vehicle as an intermediary node between the first vehicle (passing vehicle) and the third vehicle (oncoming vehicle). The second vehicle receives position information from the first vehicle, determines passing vehicle status, and relays this information to the third vehicle. This multi-hop communication approach allows notification without requiring direct high-power communication between the first and third vehicles, thus avoiding radio communication congestion while maintaining communication reliability.
2Reliability
If passing vehicle determination is performed based on position data from radio communication, then collision prevention capability is improved, but communication data requirements increase
Solution Approach 1:
The patent extracts only the essential position information needed for passing vehicle determination from the radio communication data stream. Instead of transmitting complete vehicle state data or using high-bandwidth communication protocols, the system transmits only the minimum necessary position coordinates and timing information. This allows the second vehicle to perform passing determination and relay critical alerts to the third vehicle with minimal communication data requirements, while maintaining effective collision prevention capability.
Data Source
AI summary
A vehicle control device and a vehicle control method are configured: to perform passing vehicle determination to determine whether another vehicle is a passing vehicle, based on position data included in first communication data received from the other vehicle and also position data of an own-vehicle; to transmit second communication data including a result of the passing vehicle determination and the position data of the own-vehicle; and to perform oncoming vehicle determination to determine whether the other vehicle is an oncoming vehicle, based on the position data included in the second communication data received from the other vehicle and the position data of an own-vehicle.
