A device for operating a braking system of a motor vehicle, including a first control unit for operating an ABS unit of the braking system and including a second control unit for operating a brake booster unit of the braking system. The control units are designed as application-specific integrated circuits and are connected to a microprocessor for their control, the microprocessor including a separate shut-off path for each of the circuits.

Device and method for operating a braking system of a motor vehicle

A method for actuating a valve with an electromagnetic valve drive through which electric current is conducted to open or close the valve or to hold the valve in an open or closed position includes receiving an opening signal, determining an adapted opening signal which is adapted to physical limits of the valve or valve drive, and determining a feed-forward signal for feed-forward control of an electric current to drive the electromagnetic valve drive to open the valve in reaction to the adapted opening signal. The method further includes calculating an actuation signal for actuating the valve drive using the feed-forward signal, and outputting the actuation signal.

Method for actuating a valve, and corresponding device

A device for operating an electrical consumer, in particular a solenoid valve, including at least one first circuit which encompasses an activatable first switch and a first freewheeling unit connected or connectable in parallel to the consumer, and including a control unit which is designed for activating the first switch in order to energize the consumer with a predefinable electric current with the aid of pulse width modulation. It is provided that the circuit encompasses at least one second switch and one second freewheeling unit, which is connected or connectable in parallel to the consumer, and that the control unit is designed for activating the second switch in a phase-shifted manner with respect to the first switch in order to energize the consumer.
