Abstract

Disclosed is a vehicle-based interactive communication system to ensure the safety of cyclists and pedestrians that cannot hear an approaching vehicle. The system receives profiles emitted by the personal devices of nearby road occupants, combines the profiles with environmental factors, and then emits an appropriate audio signal to warn the pedestrian, cyclist, or others of the approaching vehicle.

Interactive Communication System to Make Road Participants Aware of Quiet Vehicles

Quiet electric vehicles are difficult for roadside pedestrians and cyclists to hear; therefore, walking or biking individuals cannot detect that a vehicle is approaching from behind, the left, or the right, and cannot move further to the shoulder of the road for safety. Cyclists already have trouble with hearing vehicles because of noise from the wind.

A system or method is needed to make cyclists, pedestrians, and other users of the road aware of approaching vehicles, both conventional and electric.

The novel contribution is a vehicle-based interactive communication system for road participants. With this system, a vehicle receives the profiles emitted by personal devices of nearby road occupants (e.g., people, pets, etc.). The system combines the detected profiles with environmental factors, and then determines the appropriate sound qualities (e.g., type, volume, pitch, etc.) to emit as a warning to the pedestrian, cyclist, or others of the approaching vehicle.

This system enables safe sharing of the road between vehicles and slower moving road occupants. By hearing optimized/personalized sounds of passing vehicles, people become aware of approaching faster-moving vehicles. A person can then take measures to move out of the way such as stepping aside, moving to the right, or standing still until the vehicle has passed.

In an example embodiment, Driver A can see a cyclist ahead. The cyclist is riding too close to the middle of the road and seems a bit unstable. To implement the system and ensure the safety of the cyclist:


1. Driver A's vehicle is monitoring the surroundings while traveling on the road


2. The cyclist is wearing a wireless personal device that emits a signal


3. The system picks up the device signal:

A. Recognizes the exposed cyclist in proximity to the vehicle

    B. Reads the cyclist's profile
4. The system identifies:

A. Distance to the exposed occupants to pass (e.g., by radar calculations)

    B. Wind direction C. Noise level on street
D. Direction the cyclist is moving
E. Travel speed
5. The system accordingly determines the best method for emitting a warning sound, based on the cyclist'...
