Title: (EN) Vehicle door lock with a centrally-operated locking unit
Abstract: front page image
(EN)

A vehicle door lock having a closing element component, a locking element component and an actuating element component, the latter having a component actuating element and a securing actuating element, is connected to a central locking unit for remote controlled actuation of the securing actuation element. The actuation is effected with an electric motor and, in addition, a position monitoring is provided. The electric motor, for drive by the central locking unit is a reversible polyphase stepping motor with a phase confirming stator winding and which acts via a transmission on the lock component. The locking component is designed for a drive power which is greater than the nominal power of the polyphase stepping motor when it is permanently energized. The stepping motor is driven with a working voltage which is greater than the design voltage corresponding to the drive power for the centrally operable unit. For the position monitoring, a step monitor system is used. The polyphase stepping motor is controlled with the aid of a computer.
