  • Control device for a braking system of a vehicle, and method for operating a braking system of a vehicle
    Patent number: 9550482
    Abstract: A method for operating a braking system of a vehicle includes: establishing a first setpoint brake pressure to be set in a first wheel brake cylinder of a first brake circuit and a second setpoint brake pressure to be set in a second wheel brake cylinder of a second brake circuit; reducing first and second actual brake pressures by setting a master brake cylinder pressure to be no greater than a minimum of the first and second setpoint brake pressures, and controlling a first switchover valve of the first brake circuit and/or of the second brake circuit; and/or increasing the first and second actual brake pressures by setting the master brake cylinder pressure to be no smaller than a maximum of the first and second setpoint brake pressures, and activating a first wheel inlet valve of the first brake circuit and/or of the second brake circuit.

  • Method for determining the temperature of an electrical component with the aid of a temperature model
    Patent number: 7865327
    Abstract: A method for determining the temperature or the ohmic resistance of an electrical component, especially of a coil of a magnetic valve. The component temperature is estimated with the aid of a temperature model, which is able to determine the curve of the component temperature even during a control of the valve. The temperature model is corrected regularly based on the measured value, in this context.
