A telematics-navigation device detects that a hybrid vehicle propelled by at least two energy sources is traveling to a destination not provided to the vehicle (i.e., an unknown destination). As the vehicle travels to the destination, the device identifies a road segment between a current position of the vehicle and a next road junction that vehicle is traveling towards. A control unit determines an optimization strategy for managing the energy sources of the vehicle as the vehicle travels the road segment. The control unit executes the determined strategy.
