PEDESTRIAN WARNING SYSTEM PROVIDING ADJUSTABLE ACOUSTIC INDICATIONS
First Claim
Patent Images
1. A method for a vehicle to provide acoustic information to pedestrians, the method comprising:
- producing a first sound at a first frequency range from a first sound generator located at a front of the vehicle;
producing a second sound at a second frequency range from a second sound generator located under the vehicle;
adjusting, by a processor, acoustic characteristics of the first and second sounds based on vehicle motion data; and
adjusting the acoustic characteristics of at least one of the first sound or the second sound based on feedback collected from mobile devices in a vicinity external to the vehicle.

Abstract
Systems and methods are disclosed for a pedestrian warning system. An example disclosed method to simulate noise for an electric or noise-dampened vehicle to warning pedestrians includes producing a first sound at a first frequency range from a first sound generator located at a front of the vehicle. The method also includes producing a second sound at a second frequency range from a second sound generator located under the vehicle. Additionally, the example method includes adjusting the acoustic characteristics of the first and second sounds based on vehicle motion data.
