| 1. A motor vehicle lock, comprising:
a lock catch arranged to be positioned in at least one of an opening position, main locking position, and preliminary locking
position;
a locking pawl arranged such that in a lowered position the locking pawl holds the lock catch in at least one of the main
locking position and preliminary locking position and in a raised position the locking pawl releases the lock catch in a direction
of the opening position,
a memory element assigned to the locking pawl for realizing a memory state and arranged to maintain the memory state and with
it to maintain the locking pawl in a raised position after the locking pawl has risen and until a further functional state
of the motor vehicle lock is reached,
a control apparatus positioned within or outside of the vehicle lock and within the motor vehicle, the control apparatus arranged
to control individual functions of the motor vehicle lock,
wherein the locking pawl is releasable by motor from the memory state and then moveable in the direction of its lowered position
unhindered by the memory element, and the control apparatus is arranged to control the release by motor of the locking pawl
at a predetermined triggering time;
a memory drive for the release by motor of the locking pawl;
wherein the memory element further comprises a first control arm, the first control arm being arranged to be turned in a direction
which causes a shifting of the memory element into the raised position thereof, in which the locking pawl is released from
the memory state, and the first control arm is further arranged to engage or be brought into engagement with the memory drive
such that the first control arm may be swiveled by motor into its raised position;
wherein the memory element further comprises a second control arm arranged such that the lock catch engages the second control
arm in the memory state of the memory element during shifting of the lock catch into its opening position, and wherein a resulting
turning of the control arm leads to a raising of the memory element into its raised position, in which the locking pawl is
released from the memory state.
