ACOUSTIC VEHICLE ALERTING SYSTEM

A pedestrian alerting system adapts alerting sounds emitted by a vehicle according to an acoustic environment around the vehicle. Echoes of the alerting sound in an enclosed space such as a garage can be irritating to the pedestrians and/or occupants of the vehicle. A sensor suite including radar, cameras, and/or a GPS locator detect confined spaces in which reflections result in a greater apparent loudness. Emitted loudness of the alerting sounds are reduced, wherein the reduction of the volume may be based on the size of the space.
