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.
Claims11
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 at least one of the first sound or the second sound based on feedback collected from infrastructure nodes.
An apparatus to a vehicle to provide acoustic information to pedestrians comprising:
- a first sound generator positioned at a front of the vehicle;
- a second sound generator positioned under the vehicle;
- and
- a sound controller to:
- produce a first sound from the first sound generator;
- produce a second sound from the second sound generator;
- adjust acoustic characteristics of the first and second sounds based on vehicle motion data;
- and
- adjust 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.
A non-transitory computer readable medium comprising instructions that, when executed, cause a vehicle to:
- produce a first sound at a first frequency range from a first sound generator located at a front of the vehicle;
- produce a second sound at a second frequency range from a second sound generator located under the vehicle;
- and
- adjust acoustic characteristics of the first and second sounds based on vehicle motion data and feedback collected from infrastructure nodes.
