1. Method for regulating driving-power of a vehicle as a function of at least a distance to a destination and of an available energy supply of the energy accumulator providing the driving power, said method comprising the steps of:

  • first, at the beginning of a journey, entering journey data into a trip computer via an input unit, from which data at least a total distance to the destination can be determined;

    second, during the journey, determining at least a currently remaining distance to said destination;

    third, during the journey, measuring a remaining energy supply which is currently available in said energy accumulator;

    fourth, during the journey, determining in said trip computer a permissible nominal energy consumption rate which enables said vehicle to travel the remaining distance based on the measured currently available energy supply and determined remaining distance to the destination;

    fifth, controlling a set point value for a device for driving-power limitation based on the permissible nominal energy consumption rate so that the driving power is limited more severely the smaller the permissible nominal consumption rate determined; and

    sixth repeating said second through fifth steps throughout the journey, whereby said permissible nominal energy consumption rate is continuously updated.
