摘要:
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.

摘要:
The comfort level gear shift motor vehicle with an automated gear-shifting transmission is determined by shift parameters, which are dependent on driving parameters and on a shift program mode. The shift program mode identified through a characteristic parameter, which can vary a range of parameter values corresponding to a range of shift program modes. The method has the steps of detecting current values the driving parameters, detecting a current value of the characteristic parameter, determining respective minimum and maximum values that each of said shift parameters can assume within the range of characteristic parameter values as a function of the current driving parameter values, calculating actual shift parameter values as intermediate values between said maximum and minimum values for each of said shift parameters based on said current value of the characteristic parameter, and performing the gear shift with the actual shift parameter values.

A method of controlling an automated clutch of a vehicle includes the step of adapting a characteristic curve of the clutch through an electronic clutch management system. The adaptation is performed under at least one set of operating conditions that are represented by an operating point.
摘要:
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.

In a method for controlling an automated clutch and/or an automated transmission in a motor vehicle with an electronic clutch management system, a target value for the clutch torque is determined as an output quantity of a start-up function dependent on suitable input quantities.
摘要:
A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a select or finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.

A method of operating a motor vehicle that is equipped with sensors to detect the rpm-rates of the driven wheels includes the steps of: a) determining current rpm-rates of one or more driven wheels; b) examining the current rpm-rates for potential errors; c) detecting whether a command for a gear shift has been initiated; and d) in case an error was found in step b), taking protective measures so that the engine cannot be forced to run at rpm-rates detrimental to the safe operation of the vehicle as a consequence of executing and completing the gear shift.
