Abstract: A method for controlling a clutch assembly includes controlling an actual clutch fill pressure using open-loop pressure controls when an active fill phase is detected, and using closed-loop pressure controls when the active fill phase is complete or when an overfill condition is detected. The method supplies the actual clutch pressure according to a second set of open-loop pressure controls when a step in commanded clutch pressure is detected. The method monitors a fill pressure and time during the step, and applies the clutch pressure according to the closed-loop pressure controls when either value equals a corresponding threshold value. A clutch assembly has a piston for compressing clutch disks to initiate a shift event, an algorithm for controlling the shift event, and a sensor for determining an actual clutch pressure during the shift phases. The algorithm switches between closed-loop and open-loop pressure controls in response to different shift phases.

Abstract: A method for optimizing a shift event in a vehicle includes designating a clutch to be used as an oncoming clutch or an offgoing clutch in the shift event before executing the shift event, and processing a plurality of input values through a state observer to thereby determine, as an output value of the state observer, an estimated slip speed of the designated clutch. The method includes using a proportional-integral control module for the designated clutch (a clutch PI) to close the control loop on the estimated slip speed from the state observer, thereby smoothing a switching between state space equations in the state observer, and executing the shift event. A vehicle includes a transmission, an engine, at least one traction motor, and a control system configured for executing the above method.

Abstract: A method for controlling an automated friction clutch arranged in a drive train of a motor vehicle in the force flow between a drive engine (3) and a drive transmission (4), which is configured to close passively by spring pressure and can be disengaged and engaged by way of a pressure-medium-actuated clutch actuator (14), such that the actuation position x_K of the clutch actuator (14) or of an associated transmission element is determined and used for controlling the friction clutch (2). To improve the accuracy and reliability of the clutch actuation it is provided that in addition, an actuating pressure p_K of the clutch actuator (14) is determined and that a required change of the clutch torque M_K to a new nominal value M_K_soll takes place under pressure control, in that the actuating pressure p_K of the clutch actuator (14) is set to a nominal value p_K_soll which corresponds to the nominal value M_K_soll of the clutch torque M_K.
