  • Method and apparatus for diagnosing a malfunction of a clutch actuator
    Patent number: 6849027
    Abstract: In a method and apparatus for diagnosing a malfunction in a clutch actuator of a motor vehicle, the actual position of the clutch actuator is measured by a position sensor. Simultaneously, an estimated position of the clutch actuator is calculated by an emulation unit that emulates the function of the clutch actuator. Malfunctions of the clutch-actuator are diagnosed by comparing the actual, measured position to the estimated position.
    Type: Grant
    Filed: December 12, 2003
    Date of Patent: February 1, 2005
    Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KG
    Inventors: Jürgen Eich, Klaus Küpper, Alexander Schweizer, Ralf Enderlin, Thomas Jäger, Martin Vornehm
