Abstract
A navigation system and a wireless communication device are installed on an automobile. The navigation system determines the state vector of the automobile. The navigated state vector is periodically transmitted by the wireless communication device for use by other vehicles. The wireless communication device also receives state vectors transmitted from neighboring vehicles. The received state vectors are compared with the automobile'"'"'s current state vector by a processor. The processor drives a display that displays the relative position of the neighboring vehicles. The processor also determines the likelihood of collision with another vehicle. The processor issues display or audio cues to alert the driver. The processor may also send brake or steering commands when a driving correction should be made.
