METHOD OF MONITORING VEHICULAR MILEAGE

摘要

A navigational system (10) and a computer-based datalogger (14) are used to store data on the distances traveled by and places visited by a monitored vehicle (18). The datalogger includes a clock (24) and an on-board memory (22) that can store time-stamped records of the latitude and longitude of places visited by the vehicle. In some such systems the vehicle operator can assign a label or a location classification to selected places that he or she visits. Additionally, in some versions of the system an administrator can use a central computer (30) located at the vehicle's home base (26) to assign labels to locations where the vehicle is expected to make a stop. The central computer (30) generates a map-like graphical output that displays a point corresponding to each of the places visited. This display may also show the time spent at each place visited during an operational period.
