Abstract

This invention teaches an inventive method for tracking trip data in relation to geographic position for a vehicle. The first steps in the method involve recording trip data periodically and recording geographic position periodically. Each trip data recording is time stamped. Each geographic position recording is time stamped. The next step is saving the recorded trip data and geographic position to a database. The final step in the inventive method is graphically displaying the trip data and the geographic position, as a function of time, from the database. This invention also covers an apparatus and a system for carrying out the inventive method.

Claims

1. A method for tracking for a vehicle, both geographic position and multiple types of trip data wherein none of the types of trip data is used to determine geographic position, said method comprising:

recording multiple types of trip data not used to determine geographic position periodically and time stamping each periodic recording;

recording geographic position periodically and time stamping each recording;

saving the time stamped trip data and time stamped geographic position in a database;

electronically monitoring multiple types of trip data not used to determine geographic position and recording the trip data and geographic position when trip data indicates one of multiple predetermined trip events is occurring, thereby recording the event trip data and the event geographic position for the occurring trip event rather than waiting for a next period of one of the periodic recordings to initiate recording;

saving the recorded event trip data and event geographic position in the database;

graphically displaying the recorded trip data and the recorded geographic position as a function of time, from the database, wherein the graphically displayed time stamped trip data and time stamped geographic position is displayed differently than the graphically displayed event trip data and event geographic position.

2. The method of claim 1 wherein choosing an instant in time causes corresponding recorded trip data and recorded geographic position to be displayed.

3. The method of claim 1 wherein choosing a geographic position causes temporally corresponding recorded trip data to be displayed.

4. The method of claim 1 further comprising graphically displaying only the event trip data.

5. The method of claim 1 wherein a method for graphically displaying geographic position is further comprising:

recording geographic position periodically in terms of latitude and longitude; and

plotting the geographic position on a map containing latitude and longitude information.

6. The method of claim 1 wherein the periodic recording of trip data is based on a periodic interval of time and the periodic recording of geographic position is based on a periodic interval of distance.
