Apparatus, system, and method for adaptive engine system control with integrated global position sensing

摘要

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.

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; anddelay 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.
