  • Patent number: 11650606
    Abstract: 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.
    Type: Grant
    Filed: April 5, 2019
    Date of Patent: May 16, 2023

  • Patent number: 10840729
    Abstract: The invention relates to a method for operating an electrical system (1) having a high-voltage section (2) and a low-voltage section (3) which are electrically connected to one another by means of a DC-DC converter (4), wherein the low-voltage section (3) has at least one rechargeable energy store (8) and at least one electrical consumer (9), wherein the DC-DC converter (4) is operated on the basis of an electrical load (P) acting on the low-voltage section (3). In order to determine the load (P), provision is made for all currents flowing through the DC-DC converter (4) to be recorded and added to one another.
