Abstract

A process for triggering a electrically actuated motor vehicle door lock by a mechanical or electromechanical actuating handle. In this process, triggering takes place such that the electric motor drive always returns to an initial rest position after initial triggering and that actuation of the actuating handle for less than a minimum time does not trigger a switching function. Thus misactuations are unlikely. The operating characteristics of the motor vehicle door lock which is controlled using this process is matched as much as possible to the operating characteristics of mechanical or electromechanical motor vehicle door locks of conventional design. This facilitates acceptance among customers and prevents misoperations.
