First Claim
Patent Images
1. A collision avoidance system for an automotive vehicle, the collision avoidance system comprising:
- a visual sensory system the visual sensory system being located inside and coupled to the automotive vehicle, the visual sensory system comprising;
a first camera located in front of a driver of the automotive vehicle and which is directed toward a driver of the automotive vehicle;
a second camera located behind the driver and which is also directed toward the driver; and
a controller coupled to both the first and second cameras;
wherein the first and second cameras and the controller are configured to determine the driver'"'"'s intended forward or reverse travel direction by determining the driver'"'"'s head position and the driver'"'"'s eye position, the driver'"'"'s head and eye positions being determined by one of the first camera and the second cameras detecting edges of the driver'"'"'s lips and detecting the driver'"'"'s eyes; and
the controller being additionally configured to detect whether a transmission gear shift is positioned in either a forward or rearward direction, said controller preventing movement of said vehicle upon a conflict with a determined intended travel direction and the position of said driver gear shift.

Abstract
A collision avoidance system is provided which includes a sensory system to determine a driver'"'"'s intended forward or reverse travel direction by determination of a driver'"'"'s head and eye position. A controller is provided that is cognizant of a driver'"'"'s recent transmission gear shift to a forward or rearward direction. The controller prevents movement of the vehicle upon a conflict with the driver'"'"'s intended travel direction and recent driver'"'"'s gear shift.

8. A collision avoidance system for an automotive vehicle, the collision avoidance system comprising:
-
a visual sensory system located inside the automotive vehicle and being operatively coupled to the automotive vehicle, the visual sensory system comprising; a first camera located in front of a driver of the automotive vehicle and directed toward the driver of the automotive vehicle; a second camera located behind the driver and which is also directed toward the driver, both cameras being directed generally toward each other; and a controller coupled to both the first and second cameras; wherein the cameras and controller are configured to determine a driver'"'"'s intended forward or reverse travel direction by determining the driver'"'"'s head position and the driver'"'"'s eye position and additionally configured to determine said driver'"'"'s eye focus by determining a position of said driver'"'"'s eye pupil with respect to the driver'"'"'s eye'"'"'s sclera, wherein the driver'"'"'s eye focus into a driver side exterior rearview mirror, interior rearview mirror, passenger side exterior rearview mirror, rearview camera display, or a turn of driver'"'"'s head to look backwards, is determined by the controller to be indicative of the driver'"'"'s intent to move in the reverse travel direction, and wherein the driver'"'"'s focus into the windshield other than in a region about the interior rearview mirror is determined by the controller to be indicative of the driver'"'"'s intention to travel in a forward direction; the controller being additionally configured to determine whether a transmission gear shift is positioned to make the vehicle go in either a forward or rearward direction, said controller being configured to prevent movement of said vehicle upon the detection of a conflict with said driver intended travel direction and a position of said gear shift. upon the driver'"'"'s release of a brake for the automotive vehicle. - View Dependent Claims (9)

10. A method of avoiding collisions in automotive vehicles, the method comprising:
-
determining a driver'"'"'s head position and the driver'"'"'s eye position by detecting edges of the driver'"'"'s lips and detecting the driver'"'"'s eyes, the detection of the driver'"'"'s lips and eyes being made by either a first camera that is located in front of the driver or by a second camera that is located behind the driver, both cameras being directed toward the driver and toward each other; determining a driver'"'"'s intention to travel in either a forward or reverse direction by the determined head and eye positions; and providing the determination of the driver'"'"'s head and eye positions to a controller that is coupled to a transmission gear shift having forward and rearward travel direction positions, said controller configured to prevent movement of said vehicle upon a conflict with said driver'"'"'s intended travel direction and the travel direction position of said gear shift. - View Dependent Claims (11, 12, 14)
