ABSTRACT:
A motor-vehicle latch system has a latch having a locking element displaceable between a locked position and an unlocked position and a latching element actuatable in the unlocked condition of the latch to unlock the latch and ineffective when actuated in the locked condition of the latch. An outside door handle connected to the latching element is movable between an actuated position and an unactuated position and a key having a transponder can fit in a rotatable body carrying an electrically powered transponder reader that can read a code of the transponder of the key. An electrically powered electromagnetic coupling has one part connected to the body and another part connected to the locking lever and can be energized to close and couple the two parts together and thereby connect the body with the locking lever. An electrically powered controller connected to the transponder reader and the coupling can energize and close the coupling when the transponder in the key matches a predetermined code. A dynamo adjacent the door handle is connected to the coupling and to the controller. An energy-storage unit connected to the dynamo receives electricity therefrom and supplies it to the reader, coupling, and controller. The dynamo is coupled to the door handle for operation of the dynamo and charging of the storage unit on displacement of the handle between the actuated and unactuated positions.
