Abstract
Location information may be used to adjust the engine start/stop characteristics of a hybrid electric vehicle (HEV) in order to increase the amount of electric vehicle (EV) mode driving, particularly near a destination in which an ignition-off event may occur. Common ignition-off locations may be learned and stored in a database along with the number of ignition-off occurrences associated with each learned location. The vehicle may calculate current distance to a nearest ignition-off location stored in the database using positioning system coordinates and may determine whether to adjust one or more engine pull-ups based at least in part on the distance and the corresponding number of ignition-off occurrences.
