1. A hybrid vehicle, comprising:
- a fuel consuming engine configured to supply power to drive the vehicle;
an energy storage device disposed within the hybrid vehicle, the energy storage device configured to supply power to drive the vehicle;
a prediction processor configured to predict power demand to drive the vehicle based on changing conditions during operation of the vehicle;
a drive train coupled to cause movement of the vehicle; and
a controller configured to automatically control power flow between at least one of;
the engine and the drive train,the energy storage device and the drive train, andthe engine and the energy storage device, so as to provide the power to drive the vehicle based at least in part on the predicted power demand, wherein the power demand to drive the vehicle is greater than a maximum power available from the engine at at least one point in time during operation of the hybrid vehicle.

Abstract
Systems and methods for controlling and operating a hybrid vehicle having a high degree of hybridization are disclosed. A power flow control system predicts vehicle power demand to drive the hybrid vehicle based on changing conditions during operation of the hybrid vehicle. The power flow control system controls the power flow so as to provide power to drive the hybrid vehicle based on the predicted vehicle power demand, wherein the predicted vehicle power demand is greater than a maximum
