Abstract
An active door latch assembly having a striker mounted on a vehicle body so as to be moveable towards and away from the vehicle body, a latch mechanism mounted on a vehicle door for latching the striker thereto upon closing of the door against the vehicle body, and a motor for moving the striker along the direction of the motion of the striker. A detector detects a latched stage of the latch mechanism, and a control circuit for activates the motor so as to move the striker away from the vehicle body when the detector has detected the unlatching of the latch mechanism and towards the vehicle body when the detector has detected the latching of the latch mechanism. Because the motor is activated upon detecting of the latching, premature or belated activation of the motor can be avoided. The detection can be accomplished by detecting the motor of either a latch member which engages the striker or a pawl which engages the latch member at its latched state.
