Abstract
A wireless communication device for vehicle-to-vehicle communication includes a vehicle positioning module that uses sensors and detects a current position and a direction of the vehicle. In a map matching, pre-calculated route information and road network information based on the current position are retrieved from map data and a current link of the vehicle is identified and a potential signal pattern is determined regarding a position of next intersection and the road network information based on the current position, the direction of the vehicle and the current link. Based on the potential signal pattern, radio characteristics including a level of intensity, a frequency, and a direction are assigned. A transmitter produces a radio signal of the radio characteristics carrying the current position, the speed and the direction of the vehicle. An antenna module converts the radio signal from the transmitter into radio waves and radiates the radio waves.
