A method for preventing spinning of at least one drive wheel in a motor vehicle that has a dual clutch transmission, including the process steps of: a vehicle placed in a first gear unit of the dual clutch transmission; placement of a higher gear for the vehicle in a second gear unit of the dual clutch transmission; detecting whether the at least one drive wheel is spinning; disengaging the clutch that is assigned to the first gear unit, depending on whether spinning was detected; and engaging the clutch that is assigned to the second gear unit, depending on whether spinning was detected.

Method for preventing drive wheels from spinning

A method for altering the coupling torque of a coupling in the drive train of a vehicle with an automatic gearbox and/or automatic coupling in a creep drive mode of a vehicle. According to the invention, the coupling torque is altered according to at least one variable, the parameter of the vehicle describing the creep drive mode thereof.

Method for changing the clutch torque in a clutch in the power train of a vehicle having an automated manual shift transmission

Actuation devices are disclosed for a pressure-closed clutch where the position of an actuation member is acquired by an incremental sensor. In an embodiment of the actuation device, the signal of the incremental sensor is acquired in case of a sudden change in the power consumption of an actuator and is used as a new reference signal. In another embodiment, the actuation member, while the spindle is rotating, is moved by a recovery spring during the closing of the clutch against a stop and the signal of the incremental sensor upon the attainment of said stop is used as a reference signal.

Method for adjusting an incremental path measurement unit in an actuation device of a pressure-closed clutch as well as an actuation device

An automated transmission system includes a transmission brake which is used to apply a braking torque to the transmission, while the engine torque is negative and a transmission clutch is disengaged to effect a gear downshift, in order to avoid acceleration of the vehicle when the clutch is released and abrupt deceleration of the vehicle upon completion of the gear downshift.

Automated transmission systems

Methods and apparatus are taught for controlling the operation of a power train in a motor vehicle (), which may include controlling a clutch actuating mechanism () so as to open a clutch () in a vehicle pull mode. Then, a transmission () may be changed from a first gear position to a second gear position via a neutral position by moving a transmission actuator. At or about the same time, the ignition angle of a spark-ignited combustion engine () is preferably shifted during the gear change step to cause the combustion engine to generate a negative engine torque. As a result, engine speed is decreased when the transmission is disposed in the neutral position and a desired engine torque can be rapidly realized as soon as the transmission actuator is disposed in the second gear position. Thereafter, the clutch is closed again.

Methods and apparatus for operating a motor vehicle

A method for controlling an automated clutch of a motor vehicle, wherein the frictional engagement of the clutch is characterized by a physical friction value that changes dependent on an operating state of the clutch, has the steps of:
