modifying the delay time in response to a pattern of vehicle door openings and closings following the door lock request;

starting the timer in response to the door lock request;

locking the doom of the vehicle at the expiration of the delay time; and

further modifying the time delay in response to a change in the stored history.

8. The method of claim 7 wherein the step of further modifying comprises the steps of:

increasing the time delay if a door is opened before the end of the time delay but within a predetermined percentage of the time delay; and

decreasing the time delay if a door is opened before a predetermined percentage of the time delay.

9. The method of claim 7 further comprising the step of storing the change in stared history and the modified time delay.

10. A method for adaptively actuating a vehicle locking system for locking the doors of a vehicle, the method comprising the steps of:

activating a lock request while at least one door of the vehicle is open;

closing all doors of the vehicle;

starting countdown of a delay timer from a first predetermined time stored in memory in response to the step of closing all doors;

delaying locking of doors of the vehicle for at least the first predetermined time;

resetting the delay timer to a second delay time greater than the first predetermined time by a first incremental time in response to a door being opened when the amount of time left on the delay timer is less than a predetermined fraction of the first predetermined time but is greater than zero;

resetting the delay timer to a third delay time less than the first predetermined time by a second incremental time in response to a door being opened when the amount of time left on the delay timer is greater than a predetermined fraction of the first predetermined time;

thereafter delaying locking of doors of the vehicle for at least the second delay time or the third delay time; and

locking all doors if a door is not opened before the second delay time or the third delay time expires.

11. The method of claim 10 further comprising the step of storing in the memory the identity of the door opened and the second delay time or the third delay time in place of the first predetermined time.

12. The method of claim 10 further comprising the step of adding a third incremental time to either the second delay time or the third delay time if the door remains open for a time greater than a predetermined delay.

13. The method of claim 10 further comprising the step of adding a fourth incremental time to the first predetermined time if more than a predetermined number of doors are open or more than a predetermined number of door transitions occur before the step of activating a look request.

14. A method for adaptively actuating a vehicle locking system for locking the doors of a vehicle, the method comprising the steps of:

providing a control module comprising a delay timer and a memory, the memory configured to store door opening/closing history, including sequence of door openings, times taken for door openings and time delays associated with door openings;
