Abstract

An electric steering lock for a drive authorization system in a motor vehicle, including a movable locking element which, according to a first position, can be brought into locking engagement with a latched-in position on the steering shaft in the steering wheel column and, according to a second position, can be brought out of locking engagement with said position. The steering lock also has a drive for moving the locking element between the two positions, and electronics for controlling the drive. The system may have an associated second device in the form of an electronic key, an identification (ID) transmitter, a chip card or the like, with the result that, when the second device is authorized, the drive can be controlled into the respective position by the electronics. The electronics generate those signals which are used to trigger functions which can otherwise be effected by an electric ignition lock.
