A method is provided for controlling the current intensity of the electric current flowing through an inductive consumer, the consumer being connected in series to a switching device and a current measuring unit, and in parallel to a free-wheeling element, and the switching device being activated for adjusting the current intensity during a pulse width modulation period. It is provided that a mean load voltage to be set during the pulse width modulation period is determined from an input current intensity with the aid of a first controller, the mean load voltage being set in the pulse width modulation period with the aid of the switching device at the consumer, the mean load voltage or a setpoint load voltage determined with the aid of a second controller from a predefined setpoint current intensity being fed to a model adapted to the consumer, and the input current intensity being ascertained from the difference between the predefined setpoint current intensity and a difference variable between an actual current intensity through the consumer and a model current intensity determined with the aid of the model. A circuit configuration for implementing the method is also provided.

Method for controlling the current intensity of the electric current flowing through an inductive consumer and a corresponding circuit configuration

The use of a control module having at least one housing part and a multi-layer printed circuit board as the electrical connection between the inner space of the housing and components that are situated outside of the housing part is described. The multi-layer printed circuit board is the carrier for the electrical components of an electronic circuit, and is at the same time the thermal contacting to a housing part and/or a cooling element, particularly a hydraulic plate of the transmission, for a transmission control installed in an automatic transmission.

An electrical control unit has a printed circuit board substrate, on which an electronic circuit is situated, which circuit includes multiple electrical components which are interconnected via printed conductors of the printed circuit board substrate, as well as housing parts for covering the electrical components on the printed circuit board substrate, and at least one device plug connector part situated on the printed circuit board substrate outside the section of the printed circuit board substrate covered by the housing parts. Outside the section covered by the at least one housing part and outside the section of the printed circuit board substrate provided with the device plug connector part, at least one contact point for an additional electrical component is situated on the printed circuit board substrate.

A method and a device for monitoring at least one output stage for an inductive load using a current regulator and an analysis device are described. A short circuit to a power supply or to ground is detected by comparing at least one current value in a switching phase of the at least one output stage with at least one current value in a free-wheeling phase of the at least one output stage.

Method for extending the diagnostic capability of current regulators

A method for operating an electric control device for at least one power unit of a motor vehicle, an operating temperature range being assigned to the control device, and the control device being automatically switched off if its temperature exceeds the operating temperature range. A switch-on of the automatically switched-off control device may be implemented only if its temperature is within the operating temperature range. Furthermore, a corresponding electric control device.
