FALSE EVENT SUPPRESSION FOR COLLISION AVOIDANCE SYSTEMS
First Claim
1. A collision warning apparatus comprising:
- one or more sensors to detect one or more objects;
one or more output devices operable to output a warning to a driver;
one or more persistent memory locations to store one or more sets of vehicle GPS coordinates associated with previously identified potential collision objects;
a GPS device operable to determine present GPS coordinates of a vehicle;
and a processor in communication with the sensors, the output devices, the GPS device and the persistent memory locations, wherein the processor is operable to;
receive information from the one or more sensors and process the information to identify a detected object as a present potential collision object;
compare present GPS coordinates of the vehicle with stored vehicle GPS coordinates saved in persistent memory, to determine whether or not the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object; and
if the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object, the processor is operable to suppress a potential collision warning.

Abstract
A collision warning apparatus includes sensors, output devices, memory locations, a GPS device, and a processor. The processor may receive information from the sensors. The processor may also process the information to identify a detected object as a present potential collision object. The processor may compare present GPS coordinates of the vehicle with stored vehicle GPS coordinates saved in memory, to determine whether or not the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object. If the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object, the processor is operable to suppress a potential collision warning.

12. A warning suppression method comprising:
-
receiving information from one or more vehicle sensors; processing the information to identify a detected object as a present potential collision object; determining present GPS coordinates of a vehicle; comparing present GPS coordinates of the vehicle with stored vehicle GPS coordinates saved in a memory, to determine whether or not the present GPS coordinates correspond to stored vehicle GPS coordinates that are associated with a previously identified potential collision object; and if the present GPS coordinates correspond to stored vehicle GPS coordinates associated with a previously identified potential collision object, suppressing a potential collision warning. - View Dependent Claims (13, 14, 15, 16, 17, 18)

20. A method of collision warning event monitoring comprising:
-
receiving a collision event warning from a remote vehicle via a wireless connection from the vehicle to a local server; receiving one or more pieces of information regarding the collision event warning, including at least one of a location or a validity state of the warning; storing the collision event warning in a database of collision event warnings, including storing the pieces of information regarding the warning; and updating one or more remote systems with the collision event warning, wherein the updating includes sending the collision event warning and at least one piece of the one or more pieces of information to the remote systems.
