Abstract
A vehicle tracking system includes a vehicle tracking unit and a monitoring station communicating therewith. The vehicle tracking unit may include a vehicle position determining device, a wireless communications device, and a controller. The controller may determine the vehicle position information including a vehicle location and an associated stationary period for each occurrence of the vehicle remaining stationary for greater than a predetermined period. For example, the predetermined time may be less than about three minutes which filters out stops in normal traffic, but which will keep track of stops where the driver likely leaves the vehicle. Accordingly, only the important information necessary to track the vehicle need be stored and/or transmitted thereby reducing the system costs.
