Method and apparatus for automatic event detection in a wireless communication system
First Claim
1. A method for detecting when a vehicle has arrived at a planned stop, comprising the steps of:
- determining a vehicle speed and comparing said vehicle speed to a predetermined speed;
determining a vehicle position and comparing said vehicle position to at least one planned stop position; and
generating an indication of a vehicle arrival at one of said planned stops when said vehicle speed is less than said predetermined speed for a predetermined amount of time and said vehicle position is less than a predetermined distance from one of said planned stops.

Abstract
Apparatus and method for determining when a vehicle has arrived or departed from a planned or an unplanned stop, while minimizing or completely eliminating driver intervention. The apparatus comprises a mobile communication terminal located onboard a vehicle for receiving destination information, generally using wireless means, from a central facility or hub. A speedometer also located onboard the vehicle determines the speed of the vehicle and a position sensor onboard the vehicle determines the vehicle position. The vehicle speed and position are provided to a processor, also located onboard the vehicle, which uses the speed and position information to determine a vehicle arrival or departure from a planned or unplanned stop. The processor generates an indication of the event, either arrival or departure, directly to the central facility, to the vehicle operator, or both.

2. A method for detecting when a vehicle has departed from a planned stop, comprising the steps of:
-
determining that said vehicle has arrived at a planned stop; determining a vehicle speed and comparing said vehicle speed to a predetermined speed; determining a vehicle position and comparing said vehicle position to a position corresponding to said planned stop; and generating an indication of a vehicle departure from said planned stop when said vehicle speed is greater than said predetermined speed and said vehicle position is greater than a predetermined distance from said planned stop.

3. A method for detecting when a vehicle has arrived at an unplanned stop, comprising the steps of:
-
determining a vehicle speed and comparing said vehicle speed to a predetermined speed; determining whether or not said vehicle is at a planned stop; and generating an indication of a vehicle arrival at said unplanned stop when said vehicle speed is less than said predetermined speed for a predetermined amount of time and when said vehicle is not at a planned stop.
