Abstract: A device is provided for controlling longitudinal guidance of a vehicle designed to be driven in an at least partly automated manner. The vehicle includes an actuation element for having a driver control longitudinal guidance, the actuation element being blockable within predefined limit positions in accordance with a variable representing the degree of automation of the vehicle and a first condition. The actuation element can be unblocked in accordance with the variable representing the degree of automation of the traveling vehicle and at least one second condition.

Abstract: In a method for estimating a voltage of a battery a given electrochemical battery model is provided, wherein one parameter of the electrochemical battery model is an open circuit potential. The open circuit potential is linearized. The voltage of the battery is estimated by means of the electrochemical battery model with the linearized open circuit potential.

Abstract: A method for controlling the electrical system of a motor vehicle with a generator, a battery to supply the electrical system, at least one load and a storage capacitor for brief supply of electrical power on demand, during which the battery is charged when the generator produces excess electrical power is provided. The load is supplied and the battery and the storage capacitor are charged by the generator in load operation or fuel cutoff. The load is additionally supplied by the battery and/or the storage capacitor when the instantaneous generator power is not sufficient. An instantaneously required electrical load power in load operation or fuel cutoff is recorded the load power is compared with an idle power of the generator, and the storage capacitor is charged by the generator when the idle power of the generator is less than the load power in load operation or fuel cutoff.
