1. A vehicular power system for powering a parallel hybrid vehicle, the parallel hybrid including an internal combustion engine powered by fossil fuel, an electric motor/generator, and a battery source for powering the electric motor/generator, a inverter regulates the flow of current from the battery source to the electric motor/generator, said vehicle power system comprising:

  • a first demand map providing a first set of demand parameters for controlling the current between said battery and said electrical electric motor/generator corresponding to the operation of said vehicle in a first external operating environment simultaneously utilizing both said internal combustion engine and said electric motor to power said hybrid vehicle;

    a second demand map having a second set of demand parameters for controlling the amount of current between said battery and said electric motor/generator corresponding to the operation of said vehicle in a second external operating environment simultaneously utilizing both said internal combustion engine and said electric motor to power said hybrid vehicle;

    said first and second demand map being independently selectable from one another and;

    a selector for selecting between said first and second demand maps depending upon an external operating environment.
