Abstract

A lock arrangement for a transmission, in particular in the form of a parking-lock arrangement for an automated transmission. The lock arrangement is prestressed by a first spring accumulator into a locking position in which the transmission is locked. The lock arrangement is capable of being shifted by means of an actuator from the locking position into a release position in which the transmission is released. The lock arrangement has an electronically activatable blocking device which is designed for blocking the lock arrangement mechanically in the locking position.
