V2X Speed Control for Dynamic Traffic Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle speed control systems, such as smart cruise control, lack flexibility in adjusting speed based on driving section characteristics and neighboring vehicles, leading to potential accidents and traffic jams, especially in accident black spots where speeding is common.
Innovation Solution
A vehicle-to-infrastructure communication system that collects and analyzes driving information to generate control data for automatic speed adjustment, using a V2X terminal and integrated controller to calculate deceleration levels based on speed limits and neighboring vehicle information, and displays warning notifications to drivers through an AVN system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SCC module automatically controls engine and brake based on inter-vehicle distance, then speed control between vehicles is maintained, but quick braking occurs when distance is insufficient due to inflexible speed control
Solution Approach 1:
The system dynamically adjusts vehicle speed based on real-time driving section characteristics and neighboring vehicle information received through V2X communication. The integrated controller modifies the speed limit according to dynamic conditions such as accident black spot locations, construction zones, and traffic flow, enabling flexible speed adaptation rather than rigid maintenance of a fixed speed setting.
Solution Approach 2:
The system continuously receives feedback from V2X terminals about driving section characteristics, speed limits, and neighboring vehicle positions. This feedback loop allows the integrated controller to adjust speed control strategies in real-time, preventing situations that would require emergency braking by proactively adapting to changing conditions ahead of time.
2Reliability
If V2V/V2I communication is used for advance warning and braking, then accident prevention is improved, but traffic flow flexibility is reduced
Solution Approach 1:
The system dynamically adjusts speed control strategies based on real-time V2X communication data about driving section characteristics. Rather than applying uniform braking warnings, the integrated controller adapts speed limits and control parameters to specific conditions such as accident black spots, construction zones, and varying traffic flows, maintaining both safety and traffic flexibility.
Solution Approach 2:
The system changes control parameters including speed limits, deceleration rates, and warning thresholds based on received V2X information about driving section characteristics. The integrated controller modifies these parameters dynamically to match conditions such as urban versus highway environments, weather conditions, and traffic density, enabling adaptable response rather than fixed reaction.
3Ease of operation
If fixed speed limit is enforced, then speed control simplicity is maintained, but driving section characteristics are not considered
Solution Approach 1:
The system transforms fixed speed control into dynamic speed control by continuously receiving and processing V2X communication data about driving section characteristics. The integrated controller automatically adjusts speed limits based on received information about accident black spots, construction zones, and other environmental factors, maintaining simplicity of operation while adapting to varying conditions.
Solution Approach 2:
The system enables the vehicle to automatically adapt its speed control to driving section characteristics without requiring manual driver input. The integrated controller self-adjusts speed limits and control parameters based on V2X received information, making the system self-aware of environmental conditions and self-capable of appropriate response.

AI summary
Disclosed are an automatic speed controllable vehicle and a speed controlling method thereof. The vehicle collects vehicle information and transmitted collected vehicle information to an RSE, and the RSE receives vehicle information from each vehicle within a management section and transmits again, to each vehicle, information required for each vehicle to adjust a speed. The vehicle receiving information required to adjust the speed may adjust the speed of the vehicle based on the received information and may display a warning notification for a driver.
