  • Method and control device for operating a reciprocating piston pump
    Patent number: 10738775
    Abstract: A method for actuating a pump having a reciprocating piston or a diaphragm for pressure generation in a hydraulic system, the reciprocating piston or the diaphragm being moved by way of an actuator which is driven by a magnetic field of a magnet coil, and a system pressure in the hydraulic system being determined.
    Type: Grant

    Date of Patent: August 11, 2020
    Assignee: Robert Bosch GmbH
    Inventors: Edna Boos, Roland Waschler
  • Method for actuating an electrically controllable reducing agent dosing valve of an internal combustion engine
    Patent number: 10697341
    Abstract: A reducing agent dosing valve (24) on an exhaust system (12) of an internal combustion engine (10), having a pump (32) which generates an injection pressure (p_24), and having a control unit (14) which actuates the reducing agent dosing valve (24) with actuation signals is presented, wherein the actuation signals are formed in a manner dependent on a reducing agent pressure (p_36) prevailing at the pump side. The method is distinguished by the fact that the actuation signals are formed additionally in a manner dependent on at least one estimated value for an influence of a drop in the injection pressure (p_24), which occurs upon the opening of the reducing agent dosing valve (24), on the injected reducing agent quantity.
