Abstract:
1. A motor vehicle lock with closing elements of a lock bolt and catch, wherein the catch in a dropped position holds the lock bolt in a main engagement position or in a pre-engagement position, wherein an actuating lever is provided which, in a mounted state, is allocated to an actuating handle and, by the actuating lever's operation, the catch is configured to be lifted from the dropped position, wherein the motor vehicle lock can be brought into different function states such as “unlocked”, “locked”, “theft protected” or “child-locked”, and wherein a current function state for the motor vehicle lock is stored in a lock controller, wherein a coupling arrangement is provided by which the actuating lever, depending on function state, can be coupled with the catch to lift it, wherein from a decoupled state, a first actuation of the actuating lever always causes coupling of the coupling arrangement and lifting of the catch can be achieved by a subsequent second actuation, wherein the lock controller on first actuation transfers the coupling arrangement back to the decoupled state by means of a control drive, depending on current function state, such that the second actuation does not cause lifting of the catch, wherein the coupling arrangement has a switch element which can be shifted by means of the control drive from a coupling position to a decoupling position and depending on coupled state couples together or decouples two swivelable adjustment elements of the actuating system, and which can be shifted separately from the two adjustment elements at least in the decoupling direction or which can be shifted in a bistable manner between the coupling position and the decoupling position; wherein the switch element is arranged within the transmission chain between the two adjustment elements at least in the coupling position.
