Abstract
A method to control a hybrid electric vehicle (HEV) having a compression ignition engine includes operating the engine based on an engine-on request and performing an exhaust aftertreatment procedure based on a completion time for the aftertreatment procedure compared to a predicted engine-on time determined using a driving pattern. An HEV is provided with a compression ignition engine with an aftertreatment system, and a controller. The controller is configured to: (i) operate the engine based on an engine-on request, and (ii) perform an exhaust aftertreatment procedure for the vehicle based on a completion time for the aftertreatment procedure compared to a predicted engine-on time determined using a driving pattern. A computer readable medium having stored data representing instructions executable by a controller to control a vehicle is provided with instructions for operating the engine based on an engine-on request, and instructions for performing an exhaust aftertreatment procedure.
