Method for monitoring and reporting vehicular mileage
First Claim
1. A method of measuring a distance traveled in a trip of a first type by a vehicle having a fixed base, the vehicle carrying monitoring equipment comprising a navigational receiver for receiving a location datum at each of a plurality of times and means of storing a plurality of location records, each record comprising one of the location data and the time at which it was received, in a log file, the method comprising the steps of:
- (a) driving the vehicle away from the fixed base;
(b) storing in the log file, responsive to respective manual inputs provided by an operator of the vehicle, a plurality of time-stamped waypoint records, each waypoint record indicative of a terminus of one of the trips of the first type;
(c) returning the vehicle to the fixed base and communicating the records from the log file to a base computer;
(d) calculating from the communicated log file records, by means of an algorithm carried out by the base computer, a sequence of locations visited at which the vehicle stopped for longer than a predetermined minimum interval and a corresponding sequence of trip distances between sequential ones of the locations visited;
(e) labeling, as a trip of the first type, each trip extending between two sequential locations at which waypoint records were entered, or between one location at which a waypoint record was entered and the fixed base.

Abstract
A navigational system and a computer-based datalogger are used to store data on the distances traveled by and places visited by a monitored vehicle. The datalogger includes a clock and an on-board memory 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 located at the vehicle'"'"'s home base to assign labels to locations where the vehicle is expected to make a stop. The central computer 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.

7. A method of measuring a duration of a visit to one of a plurality of predetermined locations previously visited by a vehicle having a fixed base, the vehicle carrying monitoring equipment comprising a navigational receiver receiving a location datum at each of a plurality of times and means for storing a plurality of location records, each record comprising one of the location data and the time at which it was received, in a log file, the method comprising the steps of:
-
(a) generating a vehicle history file comprising a plurality of records, each vehicle history file record comprising a datum representative of a respective one of the predetermined locations; (b) driving the vehicle from the fixed base to the one of the predetermined locations and remaining at the one of the predetermined locations for longer than a predetermined interval; (c) returning the vehicle to the fixed base and communicating the records from the log file to a base computer; (d) calculating as the duration of the visit, from the communicated log file records, by means of an algorithm carried out by the base computer, the time greater than the predetermined interval at which the vehicle remained at the one of the predetermined locations. - View Dependent Claims (8, 9, 10)
