Abstract
A method for vehicle-to-vehicle identification and detection and a system for the same are revealed. A plurality of radio frequency (RF) communication units with different communication directions is arranged at a vehicle body. Each RF communication unit sends identification information of the vehicle to nearby vehicles in response to communication requests from the nearby vehicles. The vehicle sends communication requests to the nearby vehicles in different communication directions by antennas of the RF communication units using time-sharing polling or simultaneous communication scheme. Thus RF communication between vehicles is achieved for identification and detection of the nearby vehicles. The precise and accurate positioning of the respective vehicle within the area is achieved to support vehicle active safety control or provide data required for autonomous driving for improving driving safety.
