Fuel use categorization for fuel tax reporting on commercial vehicles
First Claim
Patent Images
1. A motor vehicle management system comprising:
- a first data link installed on the motor vehicle;
an engine installed on the motor vehicle;
fuel usage related sensors and means for placing fuel usage reports on the first data link;
data processing means having access to the first data link for reading fuel usage reports;
means coupled to the data processing means for supplying vehicle location information;
a data base accessible to the data processing means supplying public right-of-way location information; and
the data processing means including programming for execution on the vehicle body computer for determining incremental fuel usage and further programming for execution for comparing vehicle location information to the public right-of-way location information to determine if the vehicle is off a public right-of-way and to allocate any incremental fuel usage occurring when the vehicle is off a public right-of-way to a non-taxable category.

Abstract
A motor vehicle equipped with a controller area network supports vehicle management functions which categorize fuel usage by type and location of the vehicle. This allows fuel usage to be allocated between a non-taxable account and taxable accounts for each jurisdiction in which the vehicle is operated.

11. A vehicle comprising:
-
an engine;
sensors for monitoring operating variables for the vehicle and generating signals indicating values for the operating variables;
data processing means coupled to the sensors and responsive to the signals generated thereby for determining fuel flow to the engine;
means for determining vehicle location coupled to the data processing means to supply periodically to the data processing means coordinate values for instantaneous vehicle location;
a database accessible to the data processing means providing coordinates for public roads; and
the data processing means being further programmed to compare coordinate values for instantaneous vehicle location and coordinates for public roads for determining whether the vehicle is off public roads. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
