  • Method and device for operating an internal combustion engine including an electrically supported exhaust gas-driven supercharging device
    Patent number: 11391228
    Abstract: A method for operating an internal combustion engine including an exhaust gas-driven supercharging device having an electric support drive. The method includes providing an operating point specification of the internal combustion engine, ascertaining a maximum admissible recuperation output in a recuperation mode of the electric support drive as a function of the operating point specification, and limiting the recuperation output to the maximum admissible recuperation output in the recuperation mode.

  • Method for starting an internal combustion engine, device and computer program product
    Patent number: 10563634
    Abstract: The invention relates to a method for starting an internal combustion engine for a motor vehicle, said internal combustion engine having at least two cylinders, a valve drive with at least one inlet valve and at least one outlet valve for each of the cylinders, wherein at least the closing times of the inlet valves can be variably adjusted, and a direct injection system, in particular a gasoline direct injection system, the starting process being initiated by a direct injection and ignition in one of the cylinders. During a starting process, the closing time of at least one inlet valve differs from at least one of the other cylinders dependent on at least one current state value.
