Abstract

System and method for analyzing position data and fuel injector data from a vehicle equipped with a geographical position system (GPS) and fuel injector sensors to enable fuel use patterns of the vehicle to be analyzed. Data defining a flow of fuel through the vehicle's fuel injectors is combined with temporal data and GPS data to produce fuel use encoded GPS data that is transmitted to a remote computer. The fuel use encoded GPS data can be analyzed to determine how much fuel was used by the vehicle during off road use to enable proper fuel tax computations to be performed. The data can also be used to evaluate the mechanical condition of a vehicle. By monitoring fuel use for a trip repeated numerous times, a decrease in fuel efficiency may indicate a mechanical problem (dirty injectors, fouled spark plugs, etc).

First claim

The invention in which an exclusive right is claimed is defined by the following:

1. A method for automatically detecting the existence of a mechanical problem in a vehicle equipped with a geographical position system, the method comprising the steps of:
(a) collecting geographical position data from the vehicle during vehicle operation, the geographical position data being time indexed;
(b) collecting fuel injector data from the vehicle during operation of the vehicle, the fuel injector data being time indexed to define a quantity of fuel passing through an engine fuel injector at a specific point in time;
(c) combining the fuel injector data and the geographical position data together at the vehicle to produce fuel use encoded position data for a first instance of operating the vehicle on a route;
(d) combining the fuel injector data and the geographical position data together at the vehicle to produce fuel use encoded position data for a second instance of operating the vehicle on the route;
(e) conveying the fuel use encoded position data to a remote computing device that is physically spaced apart from the vehicle; and
(f) causing the remote computing device to automatically compare fuel use during the second instance of operating the vehicle on the route to fuel use during the first instance of operating vehicle on the route and if fuel efficiency has decreased, to provide an indication for inspecting the vehicle for a mechanical problem.

2. The method of claim 1 , further comprising the steps of:
(a) collecting odometer data from the vehicle during operation of the vehicle; and
(b) including the odometer data in the fuel use encoded position data such that the odometer data is also time indexed.

3. A method for generating and using fuel use encoded position data from a vehicle equipped with a geographical position system to determine at least one operational characteristic of the vehicle, the method comprising the steps of:
(a) collecting geographical position data from the vehicle during vehicle operation;
(b) collecting fuel injector data from the vehicle during operation of the vehicle, the fuel injector data defining a quantity of fuel passing through an engine fuel injector;
(c) combining the fuel injector data and the geographical position data together at the vehicle to produce fuel use encoded position data, such that the fuel use encoded position data is time indexed;
(d) conveying the fuel use encoded position data to a remote computing device; and
(e) using said remote computing device to automatically analyze the fuel use encoded position data to determine at least one aspect of the vehicle condition.

4. the method of claim 3 , further comprising the steps of:
(a) collecting odometer data from the vehicle during operation of the vehicle; and
(b) including the odometer data in the fuel use encoded position data, before conveying the fuel use encoded position data to the remote computing device.

5. The method of claim 3 , wherein the step of analyzing the fuel use encoded position data to determine at least one aspect of the vehicle condition comprises the step of comparing the vehicle's fuel usage for a first trip with the vehicle's fuel use for a second trip, where the geographical position data collected during the first and second trip indicate the vehicle traversed the same route for the first and second trips, such that a change in the fuel usage indicates a change in fuel consumption required to traverse the same route.

6. The method of claim 3 , wherein the step of analyzing the fuel use encoded position data to determine at least one aspect of the vehicle condition comprises the step of enabling a user to define a geofence, such that only fuel use encoded position data falling within the confines of the geofence are included within the analysis.
