METHOD FOR DETERMINING AND/OR OFFSETTING CROSSTALK BEHAVIOUR OF A DUAL CLUTCH TRANSMISSION
The invention relates to a method for determining the crosstalk behaviour of a hydrostatic dual clutch transmission of a motor vehicle which has two partial transmission clutches (4, 5) that are each arranged between a drive unit (2) and a partial transmission (8, 9), wherein the two partial transmission clutches (4, 5) are each actuated independently of one another via a partial transmission clutch actuator (6, 7), wherein during the actuation, the actuation pressure (p4, p5) from the partial transmission clutch actuator (6, 7) acting on the partial transmission clutch (4, 5) and a clutch actuation path travelled by the partial transmission clutch (4, 5) are determined, from which a crosstalk factor (Deltax4, Deltax5) is determined for each partial transmission clutch (4, 5). In a method for determining the crosstalk behaviour of a hydrostatic dual clutch transmission, wherein said behaviour can be determined both at the belt end and during the driving operation in the motor vehicle, each crosstalk factor (Deltax4, Deltax5) is derived from a characteristic map (K4, K5) which is generated depending on the actuation pressure (p4, p5) of both partial transmission clutches (4, 5).
