Locking device for a steering shaft and application specific integrated circuit for it

摘要

The device has a sensor arrangement with permanent magnets (24, 26) that are coupled to a bolt assembly and a steering unit, respectively, so that the magnets engage coupling positions relative to hall sensors after reaching a release position of the assembly and a rotation position of the unit, respectively. The magnets are arranged so that the positions lie in a plane to mount sensors on a circuit board arranged adjacent to the plane. An independent claim is also included for an application specific integrated circuit for use in a locking device, comprising a circuit board.
