The present invention relates to a system and method for engine idle stop control, in particular to a system and method for controlling engine idle stop in a hybrid vehicle balance the extra electrical load imposed on the vehicle during engine stop with the electrical energy saved to achieve net fuel savings. Predictive information is used to determine potential vehicle stops and corresponding stop durations during a time window. To achieve net fuel savings, the engine stop duration time must be long enough for the electrical energy savings to cover electrical load added to the system. If the predicted stop duration time is long enough to yield net fuel savings, engine stop may be initiated. If not, engine stop may be inhibited.
