A door latch and in particular a motor vehicle door latch, which is equipped with a locking mechanism consisting substantially of a catch and a pawl, further having at least one locking mechanism sensor to determine the closing/opening state of the locking mechanism, further having a control unit for evaluating signals of the locking mechanism sensors, and having a trigger sensor for opening the locking mechanism in an electro-motoric manner. According to the invention, a multiple operation of the trigger sensor regardless of the state of the locking mechanism sensor is implemented for opening the locking mechanism.

A motor vehicle door lock, particularly a motor vehicle bonnet lock, includes a ratchet mechanism which substantially consists of a rotary latch and a pawl. The ratchet mechanism interacts with a lock retainer pin on a vehicle bonnet. A retention element is additionally provided which holds the pawl in a retention position, raised from the rotary latch, during unlocking of the bonnet. The lock retainer pin continues to engage in the rotary latch when in said retention position. During a first opening process which proceeds from the retention position, the lock retainer pin transfers the retention element into a release position that releases the pawl. During a subsequent bonnet closing process, the pawl can thus engage in the rotary latch, which can be pivoted without exertion of force by the lock retainer pin at least into the hold position.

A vehicle door control system includes a courtesy switch that detects an opened/closed state of a side door, a latch actuator that performs an unlatch operation for releasing a latch that holds the side door in a closed state, an unlatch switch that is provided in a vehicle compartment and is operated by a user when releasing the latch, and a controller that causes the latch actuator to perform the unlatch operation when the unlatch switch is operated. The controller prevents the unlatch operation from being executed in a period during which the side door is in an opened state, even when the unlatch switch is operated.

A latch assembly for a motor vehicle closure system having a latch mechanism, a latch release mechanism and a power cinching mechanism. The latch mechanism is operable in a released state when a closure panel is located in an open position, in a secondary closed state when the closure panel is located in a partially-closed position, and in a primary closed state when the closure panel is located in a fully-closed position. The cinching mechanism interacts with the latch mechanism to establish the secondary closed state and is actuated for shifting the latch mechanism from its secondary closed state into its primary closed state.

A system for controlling a vehicle power tailgate includes a latch structured to be movable to a latching position when the latch is engaged with a portion of a tailgate so as to maintain the tailgate in a closed position associated with the latching position of the latch. A latch actuator operably connected to the latch to control operation of the latch. A memory is communicably coupled to the processor and stores a tailgate control module including instructions that when executed by a processor cause the processor to, responsive to receipt of a tailgate opening command, control operation of the latch actuator to attempt move the latch to an over-stroke position of the latch and, responsive to a failure to move the latch to the over-stroke position within a predetermined time period, control operation of the latch actuator to move the latch to a fully-latched position of the latch.

A motorized moveable strike assembly is provided for a vehicle door. The assembly includes a strike on the door post which is moveable by an electric motor between extended and retracted positions. A latch on the door releasably engages the strike. A switch in the latch sends a signal to the controller to actuate the motor after the latch is engaged so as to retract the strike from the extended position to fully close the door. When the latch is disengaged from the strike, the latch switch sends a signal to controller to actuate the motor so as to extend the strike from the retracted position to the extended position as to prepare for the next door closing.
