Abstract
A door closer with dynamically adjustable latch region parameters is disclosed. Embodiments of the present invention include a door closer with a control unit to intelligently control a valve to vary the operating characteristics of the door closer as needed. The control unit can repeatedly determine whether a door has reached jamb upon closing. A setting or settings for the latch region of the door can be adjusted when the door does not reach jamb. These adjustments are such that the likelihood of the door reaching jamb upon closing is increased. Jamb successes can also be monitored, so that once there have been enough successful closes, settings can be adjusted to decrease the force on the door so that the latch region parameters are constantly adjusted for changing conditions to achieve closing success with the minimum closing force necessary.
