Patent ID: 8881505

Claim:
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.
