System and method for route identification using a low cost GPS system
First Claim
1. A route identification system, comprising:
- a GPS unit adapted to collect GPS data during an instance of a vehicle traveling a route;
a processor configured to collect vehicle operating data during the instance of the vehicle traveling the route; and
a storage unit adapted to receive the GPS and vehicle operating data in a non-transitory, computer-readable medium;
wherein the processor is configured to control operation of a vehicle device during a subsequent instance of the vehicle traveling the route based on the GPS and vehicle operating data collected for a plurality of positions of the route during the prior instance of the vehicle traveling the route,wherein the processor interpolates the GPS and vehicle operating data after a predefined number of runs over the route before controlling operation of the vehicle device, andwherein the processor decreases the amount of interpolation as the number of runs over the route increases due to the aggregation of the GPS and vehicle operating data for the route.

Abstract
A system and method for identifying and analyzing a route using an inexpensive GPS system is provided. The system and method provides a location for storing GPS and vehicle operating data for at least one route, requiring a plurality of runs over the at least one route. Once a predetermined minimum number of runs have been reached, the system and method define a route segment, interpolate additional data points using the GPS and vehicle operating data, synchronize the data over the plurality of runs, and analyze the data. The analyzed data is then provided to a module capable of controlling the operation of an internal combustion engine. The analyzed data is forward-looking in that it permits anticipation of vehicle operation, and more particularly, engine and transmission operation.

12. A route identification system, comprising:
a processor configured to; collect GPS data during an instance of a vehicle traveling a route; collect vehicle operating data during the instance of the vehicle traveling the route; interpolate the GPS and vehicle operating data between adjacent received GPS and vehicle operating data points for the route; analyze the GPS and vehicle operating data to control operation of a vehicle device during a subsequent instance of the vehicle traveling the route based on the GPS and vehicle operating data collected for a plurality of positions of the route during the prior instance of the vehicle traveling the route, interpolate the GPS and vehicle operating data after a predefined number of runs over the route before controlling operation of the vehicle device, and decrease the amount of interpolation as the number of runs over the route increases due to the aggregation of the GPS and vehicle operating data for the route.

13. A computer-readable storage medium having machine instructions stored therein, the instructions being executable by a processor to cause the processor to perform operations, comprising:
-
receiving GPS and vehicle operating data during an instance of a vehicle traveling a route in a plurality of routes; interpolating the GPS and vehicle operating data between adjacent received GPS and vehicle operating data points for each route in the plurality of routes; synchronizing the interpolated GPS and vehicle operating data to correspond with a specific route in the plurality of routes; analyzing the interpolated and synchronized GPS and vehicle operating data over a plurality of runs of each route in the plurality of routes; and providing the interpolated, synchronized, and analyzed GPS and vehicle operating data to a controller to control operation of a vehicle device during a subsequent instance of the vehicle traveling the route, wherein the control is based on the GPS and vehicle operating data collected for a plurality of positions during the prior instance of the vehicle traveling the route, wherein interpolation of the GPS and vehicle operating data occurs after a predefined number of runs over the route before controlling operation of the vehicle device during the subsequent instance of the vehicle traveling the route, and wherein the amount of interpolation decreases as the number of runs over the route increases due to the aggregation of the GPS and vehicle operating data for the route. - View Dependent Claims (14, 15, 16)
