Potential accident detection assessment wireless alert network
First Claim
1. A method of detecting a potential collision between two or more vehicles and alerting an operator of the potential collision comprising:
- defining around a first vehicle a safe perimeter, the extent of the safe perimeter being determined according to one or more parameters of the first vehicle selected from the group consisting of;
speed, direction of travel, acceleration, and change of direction; and
transmitting from the first vehicle to one or more other vehicles in proximity to the first vehicle the extent of the safe perimeter defined around the first vehicle.

Abstract
Disclosed herein are systems and methods for detecting a potential collision between a plurality of vehicles and alerting the operator to the potential collision. If the operator fails to heed the alert, the system may also assume control of the vehicle until the dangerous situation is passed. In connection with these systems, each vehicle is equipped with a telematics system that defines a safe perimeter around the vehicle. The safe perimeter is constantly changed in response to the velocity and acceleration of the vehicle. The telematics system is in communication with the telematics systems of other vehicles in the vicinity and the systems exchange data about the current extent of their safe perimeters. If a telematics system detects the impingement of one of the other safe perimeters into its safe perimeter, the alert is triggered.

11. A vehicle telematics system equipped to detect a potential collision between two or more vehicles and alert an operator to the potential collision comprising:
-
a differential GPS receiver;
a computer configured to receive information containing one or more vehicle parameters selected from the group consisting of;
speed, direction of travel, acceleration, and change of direction, and to define a safe perimeter around the vehicle, the extent of which is based on one or more of the parameters; and
a transmitter for sending and the extent of the safe perimeter around the vehicle to one or more other vehicles in proximity to the vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system for detecting and preventing a potential collision between two or more vehicles comprising:
-
means for determining the position of a vehicle;
means for defining around the vehicle safety perimeter, the extent of which is based on one or more operating parameters of the vehicle;
means for transmitting to another vehicle data including the position of the vehicle and the extent of the safety perimeter around the vehicle;
means for receiving from at least one other vehicle data including the position of the at least one other vehicle and the extent of a safety perimeter around the at least one other vehicle; and
means for comparing the safety perimeter around the first vehicle to the safety perimeter around the at least one other vehicle to determine whether the safety perimeters overlap.

19. A method of detecting and avoiding a potential collision between two or more vehicles comprising:
-
detecting the presence of a second vehicle presenting a potential collision hazard to the first vehicle;
calculating the extent of a safe perimeter around the first vehicle;
establishing a communications link with the second vehicle;
receiving from the second vehicle data comprising the extent of a safe perimeter around the second vehicle;
comparing the extent of the safe perimeter around the first vehicle and the extent of the safe perimeter around the second vehicle; and
alerting the operator of the first vehicle if the safe perimeter around the first vehicle overlaps with the safe perimeter around the second vehicle. - View Dependent Claims (20)
