Patent ID: 7657184

Claim:
An interactive vehicle communication system, particularly for motor vehicles, comprising a communication device ( 2 ) for being placed on a stationary support ( 3 ) or a vehicle ( 4 ) traveling on a roadway and a receiver device ( 5 ) for being placed on a stationary support ( 3 ) or a vehicle ( 4 ′) traveling on a roadway and interacting with said communication device, wherein said communication device ( 2 ) comprises: first means ( 6 ) for interfacing with external data detection and/or generation means; an emitter device ( 9 ) with a semiconductor light source ( 14 ) for generating and emitting a visible light beam ( 8 ) with a predetermined solid angle (α) and range; digitizing means ( 7 ) for digitizing said visible light beam ( 8 ); control means ( 10 ) for suitably conforming and orienting said visible light beam ( 8 ), to allow it to selectively interact with vehicles traveling in a predetermined drive direction, and to exclude other vehicles traveling in the opposite drive direction; and wherein said receiver device ( 5 ) comprises: receiving means ( 11 ) for receiving said visible light beam ( 8 ); interfacing means ( 12 ) for interfacing with external transducers; characterized in that said semiconductor light source ( 14 ) is of the laser type and includes optical and/or electronic means ( 17 ) for generating images ( 11 ) in space or over a substantially flat surface and having a variable configuration for transmitting optical information to vehicles having no receiver device ( 5 ) mounted thereon.
