APPARATUS, SYSTEM, AND METHOD FOR ADAPTIVE ENGINE SYSTEM CONTROL WITH INTEGRATED GLOBAL POSITION SENSING
First Claim
1. A system for timing an after-treatment process in an exhaust gas after-treatment system of a motor vehicle coupled to an internal combustion engine, the system comprising:
- a controller operatively connected to the internal combustion engine, the controller configured to control the internal combustion engine and exhaust after-treatment system processes;
a geographical locator operably connected to the controller and configured to provide data to the controller for detecting a location of the motor vehicle in which the locator is housed; and
a database accessibly connected to the controller, the database storing geographic information;
wherein the controller is configured to;
determine a current load of the engine and predict a future load of the engine at a future driving location, the future driving location being based on the detected location and geographic information;
initiate an exhaust after-treatment process if a difference between the predicted future engine load and a desired engine load for an exhaust after-treatment process is greater than a predetermined threshold representing a current state of the exhaust gas after-treatment system; and
delay a requested exhaust after-treatment process until the vehicle arrives at the future location if the difference between the predicted future engine load and the desired engine load for the exhaust after-treatment process is less than the predetermined threshold.

Abstract
According to one embodiment, an apparatus includes an electronic controller (15) for an internal combustion engine (12) of a motor vehicle. The electronic controller includes a location detection module (32) configured to identify a location of the motor vehicle by a global positioning system (GPS) device (18). Also, the electronic controller includes a driving condition prediction module (34) configured to determine a direction of travel and access geographic information data for a path to be traveled by the motor vehicle. The electronic controller also has a simulation module (36) configured to simulate engine performance including effects from parasitic loads. Still further, the electronic controller includes a parasitic load control module (38) configured to adjust the timing for one or more of a regeneration process for an exhaust filter and at least one other parasitic load in order to maintain engine performance at or above a predetermined threshold.
