Abstract

This paper describes the enhancement of vehicle collision avoidance systems on a per driver basis. The improvement is achieved by the incorporation of "driver profiles", which can be used to communicate and filter information based on the characteristics, preferences, and behaviors of the driver.

METHOD FOR ENHANCEMENT OF VEHICLE COLLISION AVOIDANCE SYSTEMS BASED ON DRIVER CHARACTERISTICS

ABSTRACT

This paper describes the enhancement of vehicle collision avoidance systems on a per driver basis. The improvement is achieved by the incorporation of "driver profiles", which can be used to communicate and filter information based on the characteristics, preferences, and behaviors of the driver.

INTRODUCTION

Vehicle collision avoidance systems (VCAS) are used for the detection and prevention of vehicle collisions. They are primarily concerned with the physical aspects of the vehicle to determine potential collisions. Collision avoidance techniques used by VCAS, are solely based on the surrounding environment and the other vehicles within it.

An aspect that is not captured is the information about the individual operator and the operators around them. This could be particularly important in automobiles, where the driver's capabilities and preferences may vary widely. This paper introduces the use of "driver profiles" which capture and communicate driver information to enhance VCAS.

DESCRIPTION OF THE METHOD

In this invention, driver profiles are used to customize and enhance the VCAS. The driver profile captures any information about the driver that is deemed relevant. Information such as:

Vision or hearing impairments

Experience level

Age

Physical condition or limitations

Reckless driving behaviors

Traffic record

Driver preferred warning levels

This information would be added by the operators of the vehicle and stored by the VCAS. Each driver would simply select which stored settings to use. In the case where objective information is needed, the information could be stored on the driver's license and then swiped into a VCAS card reader. The driver profile could be used in two distinctly different ways.

For the driver's own profile, the VCAS could used this information to provide warnings based on limitations of the driver. For example, a near sighted or elderly person might want more advance warnings of impending collisions. Others may prefer to have as little warning as possible. A hearing impaired driver might choose to have a horn sounded by a nearby vehicle or the sirens of a fire engine amplified.

The system could also be configured to help train novice drivers by indicating the positions and actions of vehicles around them.

For the profiles of other drivers, the information would be received in the same manner as the other information in the VCAS. The profile would be included as part of the information transmitted by the traditional VCAS. This information could be used to warn the driver of potential hazards based on the driving capabilities of those around them.

For example, the VCAS system could warn the operator every time a driv...
