  • Patent number: 11015538
    Abstract: A method for controlling a supercharging system for an internal combustion engine, the supercharging stage including a compressor and a turbine, and the turbine being settable with the aid of a VTG driving circuit. The method including: detecting an operating state setpoint variable, setting a maximum VTG control criterion for implementing the torque increase by an increase in a boost pressure. The setting of the maximum VTG control criterion comprising: ascertaining a setpoint boost pressure; ascertaining a VTG setpoint position as a function of the setpoint boost pressure; ascertaining an actual exhaust gas back pressure; ascertaining an actual exhaust gas pressure downstream from the turbine; ascertaining a maximum exhaust gas back pressure, taking into account the actual exhaust gas pressure downstream from the turbine; determining the VTG control criterion, based on the difference between the actual exhaust gas back pressure and the maximum exhaust gas back pressure.

  • Patent number: 10876468
    Abstract: A method for controlling a turbocharging system with a turbocharging stage for an internal combustion engine, wherein the turbocharging stage comprises a compressor and a turbine and the turbine is adjustable via a VTG control. The method includes: acquiring an operating state target variable; adjusting a maximum VTG control criterion to implement the torque increase by increasing a boost pressure, wherein adjusting the maximum VTG control criterion includes: determining a target boost pressure; determining a VTG target position as a function of the target boost pressure; determining an actual exhaust back pressure; determining a maximum exhaust back pressure; determining the VTG control criterion taking into account the difference between the actual exhaust back pressure and the maximum exhaust back pressure. The VTG control criterion limits the VTG target position such that an accelerated adaptation of an actual boost pressure to the target boost pressure) takes place.

  • Patent number: 7874621
    Abstract: The seat depth adjustable motor vehicle seat comprises a first seat part, a second seat part and a longitudinal adjustment device interposed between the first seat part and the second seat part and allowing for displacement movement in a first seat direction of the first seat part relative to the second seat part. The seat further comprises a toothed rack connected to the second seat part and extending substantially in the first seat direction. A primary gear meshes with the toothed rack. A secondary gear is in rotating communication with the primary gear. A toothed bar extends substantially in a second seat direction and engages the secondary gear. A third seat part is slidably disposed in the second seat direction and is connected to the toothed bar.
