Patent attributes
Vehicle-to-pedestrian information systems that use directional sound transmission on autonomous vehicles are disclosed. A cloud computing system manages messages for transmission to pedestrians via autonomous vehicles having directional speakers. The cloud computing system identifies pedestrians and identifies messages for the pedestrians. Pedestrians may be known and authenticated to the cloud computing system or may be unknown. The cloud computing system maintains profiles for known pedestrians and transmits messages to vehicles based on the profiles. The cloud computing system keeps track of the location of vehicles and causes the vehicles to use directional speakers to transmit messages to the pedestrians based on the relative positions of the vehicles and the pedestrians.
