Abstract

A method for the determination of a motor voltage limit, wherein a clutch actuator of an automated shift transmission remains motionless, including the steps of (a) raising or lowering a withstand voltage by an increment ΔU, starting from a current withstand voltage (Ucurr), and (b) determining whether the clutch actuator moves under the changed withstand voltage.
