A circuit system for controlling an electrical consumer, the circuit system including an up-down counter, and the circuit system being configured to generate a control signal for controlling the electrical consumer, in particular for shutting off the electrical consumer, as a function of a counter content of the up-down counter. The circuit system includes a controllable clock divider circuit, with the aid of which the circuit system is configured to predefine a counting direction and a counting speed of the up-down counter as a function of at least one variable characterizing an actual current and/or a nominal current of the electrical consumer.

Circuit system for controlling an electrical consumer

A method for operating a control unit of a motor vehicle including a function unit and a monitoring unit which have a communication connection to one another. In a first check, the function unit is checked for errors, an error of the function unit being inferred if an error counter reaches a threshold value, and the monitoring unit and the function unit exchange first data with one another. In the event of a correct exchange of the first data, a positive change of the error counter is carried out. Otherwise, a negative change of the error counter is carried out. In a second check, the monitoring unit and the function unit exchange second data with one another. In the event of an incorrect exchange of the second data, a negative change of the error counter and a negative change of the threshold value are carried out.

Method for operating a control unit of a motor vehicle

In a method for controlling the heat in an internal combustion engine for a vehicle with a coolant circuit and actuable devices for influencing the heat balance of the internal combustion engine, wherein a coolant temperature and further operating parameters of the internal combustion engine are recorded, the actuable devices are operated as a function of the coolant temperature and the further operating parameters of the internal combustion engine in such a manner that an output value for determining a control variable is provided by means of a basic characteristic diagram as a function of the rotational speed and the load on the internal combustion engine, and this control value is corrected by means of a controller as a function of the coolant temperature and/or the further operating parameters.
