Method and System for Inaudible Vehicle Honk

In any crowded traffic area, different drivers sound the vehicle's horn (i.e., honk) to alert surrounding drivers or pedestrians to the vehicle's presence. A vehicle's horn sounding is heard in many directions; therefore, vehicles that are not impacted by the sound can also hear it. The vehicle's horn creates noise pollution.

    A method and system is needed that enables a vehicle's horn sound to reach and alert only the targeted vehicle(s) or individual(s), thereby reducing sound pollution. The novel solution is a method and system to use ultrasonic technology to transmit a silent vehicular horn
(i.e., honk) to a targeted receiving vehicle or mobile device.

    Ultrasonic technology transmits data, but the frequency range is beyond human hearing. A vehicular honk is of a known/calibrated wavelength. Receiver vehicles employ the Doppler Effect by determining the apparent/observed wavelength of the silent honk. The receiving vehicles assign a probability, based on Doppler Effect results, of being the targeted recipient (i.e., whether the silent honk is meant for the vehicle). Using the Doppler Effect, the system can estimate the speed, the overtake time, or the estimated time of arrival (ETA) of the approaching/receding vehicle.

    The ultrasonic (or other wave means) data transmission system replaces the current vehicle horn system. When the driver activates the horn (by pressing a button, etc.), the installed software uses ultrasound to transmit information to the surrounding area. The system can use the Doppler Effect to determine whether the source is moving toward or away from the receiver. Other parameters that can be included in data analysis include:

· Current location
· Direction of movement
· Speed of the approaching/receding vehicle
· Vehicle parameters (e.g., dimension, emergency vehicle, etc.)

    The ultrasonic data-receiving module installed in the surrounding vehicles or mobile devices receive the ultrasound signal from the surrounding area and accordingly analyze the received data to calculate whether the receiving vehicle/device is the target recipient of the alert. It does this by analyzing the direction of source, direction of movement, etc. Based on the data analysis, if the system determines that the receiving vehicle or device is the alert's target, then the mobile device or vehicle translates the signal and displays an audio/video signal or initiates a haptic effect to alert the driver to the oncoming vehicle.

    The sending vehicle can include a verbal message with the ultrasonic honk. For example, the vehicle is transporting a sick individual and wants to overtake the vehicle in front of it to get to the hospital, so the driver transmits a verbal message to that effect. The receiving vehicle receives the data from the ultrasonic transmission and accordingly displays the message in the target vehicle.
