Abstract
A method for regulating a charging state of an energy accumulator for a vehicle with a hybrid drive includes detecting a driving speed variable value of the vehicle and determining a nominal charging state of the energy accumulator as a function of the driving speed variable value by a control unit, detecting an actual charging state of the energy accumulator, comparing the actual charging state with the nominal charging state by the control unit, switching on an energy consumer by a charging state regulator, for at least partially discharging the energy accumulator when the actual charging state exceeds the nominal charging state, tabulating a first nominal charging state value as a function of the driving speed variable value by a characteristic curve, in order to determine the nominal charging state of the energy accumulator, and adapting the characteristic curve by the control unit when the vehicle is braked.
