Abstract:
1. A method for regulating a charging state of an energy accumulator for a vehicle with a hybrid drive comprising: detecting a driving speed variable value of the vehicle by a driving speed detection device 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 by a charging state detection device; comparing the actual charging state with the nominal charging state by said 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 said control unit when the vehicle is braked, whereby a correction value determined by said control unit is added to the first nominal charging state value of the characteristic curve, said first nominal charging state value being associated with a real-time driving speed variable value during braking, and the first nominal charging state value which is increased or decreased by adding the correction value is stored as a new nominal charging state value of the characteristic curve for the real-time driving speed variable value, wherein the correction value is determined by:
