  • Patent number: 8688330
    Abstract: A first operator control function is activated if it is detected by means of a first sensor that a first physical variable is higher than a predetermined first threshold value. In a similar way, a second operator control function is activated if it is detected by means of a second sensor that a second physical variable is higher than a predetermined second threshold value. A third operator control function is activated if it is detected by means of the first sensor that the first physical variable is higher than a predetermined third threshold value and if at the same time it is detected by means of the second sensor that the second physical variable is higher than a predetermined fourth threshold value, the third threshold value being higher than the first threshold value.

  • Patent number: 7932627
    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.
