Abstract
Systems, devices, and methods for alerting pedestrians as to the presence of a vehicle are provided. The system for providing alert tones may include a personal communication device, such as a mobile terminal, a vehicle communication system, and an output device. A driver of a vehicle equipped with a vehicle communication system may select an alert tone to download to his vehicle directly using the vehicle communication system or indirectly via a communications link between the personal communication device and the vehicle communication system. Upon approaching a pedestrian, the driver may actuate the vehicle communication system to sound the alert tone through the output device by interacting with an input device, such as a button or a switch. Actuation may also be caused by a voice command or automatically, through the detection of an object within a certain distance of the vehicle via one or more sensors.
