Abstract: A method of controlling a dual clutch transmission power on up shift including an on-coming clutch and an off-going clutch. The method includes implementing a prep phase comprised of decreasing torque on the off-going clutch, monitoring the off-going clutch speed to determine a slip point, and adding a bump torque to the off-going clutch when the off-going clutch reaches the slip point. The method implements a torque phase transferring torque from the off-going clutch to the on-coming clutch by increasing torque on the on-coming clutch towards an engine torque, decreasing torque on the off-going clutch, and simultaneously keeping the combination of torques greater than the slip point.

Abstract: Methods and apparatus are taught for controlling the operation of a power train in a motor vehicle (1), which may include controlling a clutch actuating mechanism (20) so as to open a clutch (3) in a vehicle pull mode. Then, a transmission (4) 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 (2) 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.

Abstract: A motor vehicle transmission is shiftable in a track pattern with a selector track and shift tracks. A shifter element moves along the tracks when the transmission is shifted from one gear ratio to another. The shifts are directed by a control device sending command signals to an actuator device which, in turn, applies an actuating force to the transmission. A main position-detecting device detects the position of the shifter element relative to the selector track and shift tracks, and a redundant position-detecting device performs an additional, redundant determination of the shifter-element position.

Abstract: A clutch-actuator device is equipped with a position-detecting device for detecting at least one of the different possible positions of engagement, disengagement and partial engagement of a clutch that serves to control the amounts of torque being transmitted between two rotary components of a torque-transmitting mechanism. The position-detecting device performs its detecting function independently of any measurement of the clutch position which may be performed by a displacement-measuring device.
