Method for determining clutch parameters of an automatic transmission having at least one clutch

A method for determining at least one of transmission or clutch parameters of a motor vehicle automatic transmission having at least one clutch or an automated manual transmission or a dual clutch transmission, for basic calibration of the automatic transmission, the method comprising the following steps:

• determining at least one of a drag torque or a kiss point of the at least one clutch by using at least one actuable synchronization device;
• providing the at least one clutch with a drive side being actively connected to or configured to be actively connected to an internal combustion engine output shaft and providing the at least one clutch with an output side being actively connected to at least one transmission input shaft;
• blocking at least one of the internal combustion engine output shaft or the transmission input shaft;
• driving the drive side of the at least one clutch by using an electric motor;
• providing at least one freewheel-shifted gear stage;
• and
• driving the drive side of the at least one clutch in a direction of rotation of the electric motor being opposite to a direction of rotation of the internal combustion engine output shaft.
