Vehicle Passing Warning System Using V2V Communication

The patent introduces a controller as an intermediary that receives vehicle information from multiple sources (vehicle sensor, GPS module, communication module) and processes this data to calculate passing required distance and assess passing safety. This intermediary system automates the complex measurements and calculations that would be difficult for drivers to perform accurately manually, thereby improving measurement precision while accepting increased system complexity.

The controller serves multiple functions: it calculates passing required distance, determines vehicle locations using GPS, receives and processes communication data from other vehicles, and provides warning outputs. By consolidating these diverse functions into a single multi-functional controller, the system achieves high measurement precision for passing safety assessment without proportionally increasing overall system complexity.

The patent replaces the manual visual detection mechanism with electronic detection systems including communication modules that exchange vehicle information and GPS modules that track vehicle locations. These electronic systems can detect and recognize opposite-direction vehicles in curved sections where visual recognition is difficult, significantly improving detection capability while accepting increased system complexity.

The controller acts as an intermediary that processes communication data from other vehicles and GPS location information to determine the presence and position of opposite-direction vehicles. This intermediary processing system overcomes the limitations of manual visual recognition, especially in curved sections, by automatically analyzing data from multiple sources to assess vehicle locations and passing safety.

The system continuously collects and processes vehicle information, GPS locations, and communication data in advance before a passing maneuver is initiated. By performing these information gathering and processing actions preliminarily and continuously, the system maintains up-to-date awareness of the passing environment, improving reliability without adding significant delay when the actual passing decision is made.

The system implements continuous feedback loops where vehicle information, GPS data, and communication messages are constantly received, processed, and used to update the passing safety assessment. This real-time feedback mechanism ensures that the most current information is available for decision-making, improving reliability while keeping processing time minimal through efficient continuous operation rather than batch processing.
