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.

A method for influencing a shift process connected with a change in transmission ratio when driving a motor vehicle that has a set of driven wheels subject to longitudinal and transverse forces, the method including detecting whether or not the vehicle is traveling around a curve and, if doing so when the shift process is in progress, influencing the shift process so as to decrease the longitudinal forces that act on the driven wheels as a result of the shift process. Also disclosed is an apparatus for performing the disclosed method including a detector for detecting whether or not the vehicle is traveling around a curve and a transmission ratio shifter responsive to the detector that, if the vehicle is traveling around a curve when the shift process is in progress, performs the shift process so as to decrease the longitudinal forces that act on the driven wheels as a result of the shift process.
