  • Method for the open-loop control of an electrically controllable valve in a vehicle transmission
    Patent number: 11913506
    Abstract: A vehicle transmission includes a hydraulic circuit and a control unit. The control unit is configured to: obtain (20) a target pressure specification; convert (26) the target pressure specification into a target volume flow rate; determine (42) a valve volume flow rate as a function of the target volume flow rate and as a function of parameters that represent system properties of the hydraulic circuit; determine (46) a pressure drop at a valve due to flow forces as a function of the valve volume flow rate; determine (48) a compensated valve output pressure as a function of the valve volume flow rate and the pressure drop; determine (58) the electric control current as a function of the compensated valve output pressure; and activate a valve with the electric control current.

  • Damper for a high-pressure pump
    Patent number: 9828988
    Abstract: A damper for a high-pressure pump includes a housing and a cover that can be coupled to the housing to form a damping space. The cover has an elevation including a plurality of concave regions and a plurality of convex regions, wherein the concave and convex regions are arranged about a central region of the elevation. Each of the concave regions is arranged between two of the convex regions in order to scatter sound.
