  • Patent number: 11524665
    Abstract: A method for initializing an electronically slip-controllable power braking system after a startup and an electronically slip-controllable power braking system. Power braking systems are equipped with a pressure generator for conveying pressure medium in a pressure medium circuit. The pressure generator includes a plunger unit made up of a plunger cylinder, a plunger piston, and a plunger work chamber enclosed by plunger cylinder and plunger piston. A characteristic, using which an actuation of the plunger piston is carried out by the motor during the initialization of the power braking system, is selected by the electronic control unit as a function of a piece of information present about the position of plunger piston at the start of the initialization and implemented by corresponding electronic activation of the motor.

  • Patent number: 11498542
    Abstract: A method for operating a brake system of a vehicle in a maintenance mode and in a normal mode includes providing a brake pressure in the brake system in the normal mode using a brake pressure generator. The method further includes preventing a provision of a brake pressure by the brake pressure generator in the maintenance mode.

  • Patent number: 11404862
    Abstract: A method is described for operating an electrical system, in particular, of a motor vehicle, which includes at least one electrical consumer, at least one energy source for electrical energy, and at least one control unit, the consumer being test activated by the control unit for the purpose of initializing a start of the system and a voltage level of an electrical voltage in the system being monitored and compared to a predefinable minimum value, and the activation being interrupted if the voltage level falls below the minimum value, and the consumer being subsequently test reactivated. It is provided that the number of the interruptions is counted and the consumer is deactivated at least for a predefinable period of time upon reaching a predefinable maximum number.

  • Publication number: 20220024430
    Abstract: A braking system includes an actuating unit for specifying a braking intention, and multiple braking devices. A first braking device includes a wheel brake, onto which a drivable pressure generator is able to apply a pressure medium, which is under braking pressure, the pressure generator being contactable with a pressure medium reservoir via a supply line. A second braking device, for converting kinetic energy of the motor vehicle into electric energy, is equipped with a drivable electric machine. The two braking devices jointly contribute to the generation of the braking power of the braking system, the respective proportion of a braking device in the braking power being variable. A connection is established, through which pressure medium is able to flow, from the wheel brake to the pressure medium reservoir using an electronic control unit, when the second braking device is able to itself generate the braking power.
