Abstract

Communications (DSRC) which involves vehicle to vehicle and vehicle to infrastructure communications can save lives by warning drivers of an impending dangerous condition or event. Dangerous condition detection functions through the application of the three P's: perceive, process, and present. Sensors in the vehicle perceive the problem; processors calculate the likelihood of an event and the information is presented to the driver. Within this document the problem of presenting the information to the driver of a vehicle in a non-distracting manner is addressed.

ABSTRACT

Communications (DSRC) which involves vehicle to vehicle and vehicle to infrastructure communications can save lives by warning drivers of an impending dangerous condition or event.  Dangerous condition detection functions through the application of the three P's: perceive, process, and present.[i] Sensors in the vehicle perceive the problem; processors calculate the likelihood of an event and the information is presented to the driver.[ii] Within this document the problem of presenting the information to the driver of a vehicle in a non-distracting manner is addressed.

PROBLEM

In-vehicle displays, heads-up displays and notifications are distracting to a driver. This includes navigation systems and text based message signs. Navigation systems have proven to be a problem and most manufacturers force the driver to push a button on the screen accepting the manufacturers disclaimer prior to enabling any map displays. Even chimes which sound to direct the driver to text based message signs in the dash are distracting as they force the driver to look away from the road.  

 

SOLUTION

To facilitate information delivery to a driver of a target vehicle in a non-distracting manner, the display capabilities on the exterior of other, nearby vehicles can be used.  Such display capabilities may include brake lights and turn signals already in current use on vehicles today or may include enhanced display capabilities such as message signs which are built into all vehicles explicitly for conveying information to other drivers.  Since drivers routinely watch the movements of other vehicles and observe indicators on those vehicles, additional information is provided without distracting the driver of the target vehicle.

Information routing to an appropriate display can work in one of two ways: source routed or target routed. To enable this capability, both an awareness of the available displays which would be appropriate to display information to the target driver and information that would be of value to the target driver are required. Sources of information that are of value to drivers already exist in the driving environment of today.  They include information about traffic signals such as phase timing.  Also included may be the outputs of traffic density sensors as well as pavement condition sensors which may be located at the side of the road.  Other vehicles on the road nearby may also be information sources.  The activation of a traction control system on a nearby vehicle gives a driver information about the nature of the roads his vehicle is or soon will be traveling over.  Conveying the information requires both the wireless communications medium (DSRC) to allow the various sources to supply data to a de...
