Abstract

A motor vehicle lock for a flap of a motor vehicle. The motor vehicle lock is equipped with a lock catch for engaging with a closing part in a holding manner and a pawl which is paired with the lock catch and which locks an opening of the lock catch in the lowered position and releases the lock catch in a raised position, wherein the motor vehicle lock has an electric closing drive and a control assembly, wherein the control assembly actuates the closing drive in a closing routine so as to move the lock catch in the closing direction from a starting position. The control assembly actuates the closing drive in the closing routine so as to move the lock catch from the starting position into a delay position in order to carry out a delay action and then move the lock catch into the main closing position.

First claim

The invention claimed is:

1 . A motor vehicle lock for a flap of a motor vehicle, wherein the motor vehicle lock is equipped with a lock catch for engaging with a closing part in a holding manner and a pawl, which is assigned to the lock catch and which locks an opening of the lock catch in a lowered position and releases the lock catch in a raised position,
wherein the motor vehicle lock has an electric closing drive and a control assembly, wherein the control assembly activates the closing drive in a closing routine so as to move the lock catch in a closing direction from a starting position into a main closing position, wherein the control assembly activates the closing drive in the closing routine so as to move the lock catch from the starting position into at least one delay position in order to carry out at least one delay action and then move the lock catch into the main closing position, wherein, in the at least one delay action, the control assembly activates the closing drive so as to move the lock catch counter to the closing direction, wherein the at least one delay position is provided between the starting position and the main closing position.

2 . The motor vehicle lock as claimed in claim 1 , wherein in the at least one delay action, an activation by the control assembly is absent for a predetermined time period.

3 . The motor vehicle lock as claimed in claim 1 , wherein the at least one delay position comprises a plurality of delay positions and the at least one delay action comprises a plurality of delay actions, corresponding to the plurality of delay positions, and wherein the control assembly activates the closing drive in the closing routine so as to move the lock catch successively into the plurality of delay positions in order to carry out the corresponding delay actions.

4 . The motor vehicle lock as claimed in claim 1 , wherein the control assembly in the closing routine initiates the output of a warning signal.

5 . A method for operating a motor vehicle lock for a flap of a motor vehicle, wherein the motor vehicle lock is equipped with a lock catch for engaging with a closing part in a holding manner and a pawl, which is assigned to the lock catch and which locks an opening of the lock catch in a lowered position and releases the lock catch in a raised position,
wherein the motor vehicle lock has an electric closing drive and a control assembly, wherein the closing drive is activated by the control assembly in a closing routine so as to move the lock catch in a closing direction from a starting position into a main closing position, wherein the closing drive is activated by the control assembly in the closing routine so as to move the lock catch from the starting position into a delay position in order to carry out a delay action and then move the lock catch into the main closing position, wherein, in the at least one delay action, the control assembly activates the closing drive so as to move the lock catch counter to the closing direction, wherein the at least one delay position is provided between the starting position and the main closing position.

6 . The motor vehicle lock as claimed in claim 1 , wherein the starting position is a pre-closing position.

7 . The motor vehicle lock as claimed in claim 1 , wherein the control assembly in the closing routine with the movement of the lock catch into the at least one delay position and/or with the at least one delay action, initiates the output of a warning signal.

8 . The motor vehicle lock as claimed in claim 7 , wherein the control assembly initiates the output of the warning signal via an optical and/or an acoustic warning device assigned to the motor vehicle lock.

9 . The motor vehicle lock as claimed in claim 4 , wherein the control assembly initiates the output of the warning signal via an optical and/or an acoustic warning device assigned to the motor vehicle lock.

10 . The method for operating a motor vehicle lock as claimed in claim 5 , wherein the starting position is a pre-closing position.
