Patent Images
1. An inter-vehicle communication apparatus, comprising:
- a communication unit configured to perform communication with another vehicle;
a positioning unit configured to obtain positional information of a vehicle; and
a controller configured to synchronize time instances of transmitting/receiving messages to/from the other vehicle using a signal from the positioning unit, to set communication conditions based on communication congestion with the other vehicle, to perform transmitting/receiving messages to/from the other vehicle at the synchronized time instance according to the communication conditions, and to determine the communication congestion with the other vehicle by utilizing channel busy percentage (CBP) of a corresponding communication environment with the other vehicle.
