Abstract (en)

[origin: WO2006074621A1] A method for determining the synchronous force when shifting a twin clutch transmission of a motor vehicle contains the following steps: preparing a situation table that defines typical shifting situations based on currently active gears, currently engaged gears of the inactive shaft, target gears, and of at least one operating parameter of the motor vehicle; preparing an assignment table that assigns predetermined synchronous forces to typical shifting situations; detecting an intention to shift; determining the typical shifting situation corresponding to the respective intention to shift, and; establishing the synchronous force, which corresponds to the determined typical shifting situation, from the assignment table.
