METHOD FOR ENHANCEMENT OF VEHICLE COLLISION AVOIDANCE SYSTEMS BY TRANSLATION OF EVENTS TO ALTERNATE HUMAN SENSES PF2118NA

ABSTRACT

This paper describes the translation of vehicle events captured by a wireless Vehicle Collision Avoidance System (VCAS) into multiple different presentation mechanisms. The improvement allows audio cues and/or events to be turned into visual indicators, voice descriptions, or mechanical vibration notifications.

INTRODUCTION

In today's automotive environments, it can sometimes be difficult to hear external events, especially if they are some distance away. For example, at highway speeds, it is nearly impossible to hear police/fire/ambulances until the emergency vehicle is in close proximity. In addition, many people have hearing and vision impairments, which make it difficult for them to detect certain types of external events.

Vehicle collision avoidance systems (VCAS) are used for the detection and prevention of vehicle collisions. Advanced VCAS would integrate GPS and vehicle sensors to allow vehicles to broadcast various events occurring within the vehicle.

These events could include location/speed/direction information, vehicle breaking, emergency vehicles approaching, etc.

This information is used by VCAS to predict potential collisions, but it can also be displayed to other drivers. Since this information is digital in nature, it can be presented to a driver in multiple forms. Some drivers may prefer audio warnings, while others may prefer visual cues. Allowing the driver to customize the presentation medium would improve the effectiveness of the system by matching it to the driver's preferences.

DESCRIPTION OF THE METHOD

Drivers behave differently to different types of stimuli, so presenting VCAS information using a fixed media type would reduce system effectiveness. A solution is to broadcast various "events" as part of the telemetry stream to allow the local vehicle's VCAS to inform the driver in a user-specified fashion. Notification types would vary depending on the capabilities of the installed VCAS, but these could include:

Text display via "Heads Up Display" (HUD)

Audio warning via vehicle stereo system

Dashboard indicator lights/messages

Driver seat vibration patterns

Emergency vehicles equipped with VCAS could broadcast "Clear the road" events, which would be received by each vehicle in range. Filtering would be done using additional VCAS data to remove false notifications (vehicles in other lane, on side roads, etc.).

This would reduce accidents and improve emergency crew response times by reducing the dependence on the driver's monitoring of mirrors and their external environment.

This mechanism could also be used to enhance the driver's notification options when "collision threats" are identified by VCAS. Notifi...
