Abstract
A method for protecting the electric drive of a vehicle against overload when the nominal power is temporarily exceeded includes measuring the traveling speed of the vehicle. The traveling speed is automatically limited for preventing a continuous speed obtained at nominal operation of the electric drive corresponding to traveling resistances independent of acceleration, from being exceeded.
