Abstract
A motor vehicle lock for the door of a motor vehicle which can be locked from the outside, preferably with a key and locking cylinder. The lock mechanism includes a force application element which is preferably a cylindrical nut that can be turned around an axis of rotation, and includes a measurement system for detecting the position of the nut. The measurement system can have at least one stationary sensor and at least one measurement element which is dynamically coupled to the nut of the lock and is located in the measurement range of the sensor in order to detect the position of the nut. The measurement element is located directly on the outside cylindrical surface of the nut while at the same time is made as a component which is separate from the nut of the lock.
Claims28
Motor vehicle door lock comprising
- a lock mechanism including a force application element in the form of an essentially cylindrical nut adapted to rotate around an axis of rotation,
- a measurement system for detecting the position of the nut including at least one stationary sensor and a least one measurement element which is dynamically coupled to the nut and located in a measurement range of the sensor in order to be detected for determining the location of the at least one measurement element, and, as a result, the location of the nut,
- wherein the nut and the measurement element are separate components and are dynamically coupled in the installed state,
- wherein the measurement element is positioned in an essentially coaxial relation to the nut in an un-installed state and wherein the nut is at least partially enclosed by the measurement element in an installed state.
