NOVELTY - The system (10) has an electric motor (16) receiving power from a supplemental power source i.e. direct current battery (26) and/or a main power source (12), and driving a hybrid vehicle. A self-learning control unit (28) is responsive to information from a global positioning system (GPS) receiver (30) and information from a set of inputs associated with the vehicle. The self-learning control unit uses the information to make predictions about future driving conditions of the vehicle to efficiently utilize main and supplemental power sources.    USE - Self-learning satellite assisted navigation hybrid vehicle system.    ADVANTAGE - The self-learning controls unit optimizes power distribution between the main power source and the supplemental power source to reduce fuel consumption, reduce emissions and/or improve performance of the vehicle. The controls unit slowly raises state-of-charge (SOC) of the battery prior to typical performance demand within commute, thus preventing high power demand of the power source from reoccurring in later commutes. The state-of-charge of the battery typically needs to be low in city-type driving conditions and high for high power demand or high load situations to optimize vehicle efficiency. The system determines and/or predicts future power demands of a hybrid vehicle to enable the state-of-charge of the battery or ultracapacitor to be prepared for high power demand events. The self-learning controls unit uses the information to make predictions about future driving conditions of the vehicle to efficiently utilize the main and supplemental power sources.    DETAILED DESCRIPTION - The main power source is an internal combustion engine or a fuel cell stack. An INDEPENDENT CLAIM is also included for a method for a self-learning assisted operating method for a hybrid vehicle.
