  • Publication number: 20240337547
    Abstract: A sensor device for torque measurement includes a substrate, a first conductor track, and a second conductor track. The first conductor track and the second conductor track are arranged on the substrate, and each of the first conductor track and the second conductor track includes at least one region having meander-shaped structures. The structures of the first conductor track and the structures of the second conductor track are each continuously connected to each other via connecting sections. The structures make it possible to determine the torque load on the substrate. The structures of the first conductor track and the structures of the second conductor track extend in an alternating manner along a curve.

  • Patent number: 11136929
    Abstract: A device and method for controlling an internal combustion engine having a catalytic converter. At least one actuating variable for the internal combustion engine is determined as a function of a system model of the catalytic converter and/or the internal combustion engine. The system model, a setpoint variable for the control and/or the actuating variable is adapted. Information about a modeled residual oxygen content in the exhaust gas downstream from the catalytic converter is determined using the system model. Information about an acquired residual oxygen content in the exhaust gas at the output of the catalytic converter is acquired. The information about the modeled residual oxygen content is compared with the information about the acquired residual oxygen content. A measure for an adaptation requirement is determined as a function of the result of the comparison.

  • Patent number: 10859017
    Abstract: A method for controlling a filling level of an exhaust gas component accumulator of a catalytic converter in the exhaust gas of an internal combustion engine where an actual filling level of the accumulator is determined with a first catalytic converter model. The method includes forming a lambda setpoint is formed, wherein a predetermined target fill level is converted into a base lambda setpoint via a second system model reverse of the first catalytic converter model, a deviation of the actual fill level from the predetermined target fill level is determined and processed to a lambda setpoint correction value via a fill level control unit, a sum of the base lambda setpoint value and the lambda setpoint value correction value is formed, and said sum is used to form a correction value, with which fuel metering to at least one combustion chamber of the internal combustion engine is influenced.

  • Publication number: 20190309698
    Abstract: The invention relates to a method for controlling a filling level of an exhaust gas component accumulator of a catalytic converter (26) in the exhaust gas of an internal combustion engine (10), in which an actual filling level (?mod) of the exhaust gas component accumulator is determined with a first catalytic converter model (100).
