Abstract (en)

[origin: DE19711563A1] The invention relates to a circuit for controlling an electrically operated motor vehicle door lock or similar, comprising a latch mechanism (1) and a detent pawl (2) which holds said latch mechanism (1) in a closed position, and an electromotive lock auxiliary drive mechanism (4) which is switched on once said latch mechanism (1) has reached a pre-closed position and then moves said latch mechanism (1) over by motive means into the main closed position. A switch (16) which detects the pre-closed position, especially a latch switch which senses the position of the latch, is also provided. The circuit has an especially simple design since the negative pole (18) of the lock auxiliary drive mechanism (4) is constantly connected to earth or negative potential and the positive pole (19) is switched and connects to either the positive potential of the vehicle electrical system or earth or negative potential, or is open (floated), and since only one switch (16) is provided and the switch (16) lies between earth and a switch connection (20) and effects a connection of said lock auxiliary drive mechanism (4). It is particularly useful if said lock auxiliary drive (4) switches off automatically when said latch mechanism (1) reaches the closed position especially when said latch mechanism reaches the extra travel position which lies just beyond the closed position, i.e. especially when the positive pole (19) of said lock auxiliary drive mechanism (4) is then connected to earth or negative potential or is open. This applies especially when the criterion for disconnecting said lock auxiliary drive mechanism (4) when the closed position is reached, especially when said latch mechanism reaches the extra travel position located just beyond the closed position mechanism is the current consumption of said lock auxiliary drive (4).
