Methods and systems for monitoring a vehicle. In a parked state of the vehicle, the control unit of the vehicle is deactivated, and the signals of some of the sensors of the vehicle are detected and evaluated by way of a separate detecting unit. If, based on the sensor signals evaluated in this way, a defined event is detected, the previously deactivated control unit can be activated. Thus, the operating time of the control unit is minimized over the total life span of the vehicle.

The present invention relates to a method for connecting multiple battery cells () of a battery (), wherein the multiple battery cells () can be connected in series to one another, and a single first control variable Pand a single second control variable Pare predefined for all the battery cells (). In this context, in order to generate a desired output voltage of the battery (), each battery cell () is electrically coupled to the battery () with a corresponding first probability, defined as a function of the first control variable P, and in each case electrically decoupled from the battery () with a corresponding second probability, defined as a function of the second control variable P. In addition, a value of the first control variable Pand a value of the second control variable Pare respectively predefined repeatedly with an update frequency which is dependent on the desired output voltage of the battery () which is to be generated.

A device for controlling an electrically actuable valve having a valve coil, including a main switch, situated in the current circuit of the valve coil, for adjusting the current flowing through the valve coil, and a freewheeling path, which has a freewheeling diode and is switched in parallel with the valve coil. A freewheeling switch is provided, by which the freewheeling path is able to be interrupted or closed. This allows for optionally operating the valve in a PMW or in a switching operation.
