Abstract
The invention relates to a circuit for selectively actuating drive elements (1, 2), which are operated on direct current, in a motor vehicle by means of half-bridges (4, 5). According to the invention, the circuit is designed for selectively actuating eight drive elements (1, 2) for locking and, respectively, unlocking four doors of the motor vehicle from the outside and/or from the inside. The circuit contains nine half-bridges (4, 5), wherein the outputs of eight of the nine half-bridges (4) are each connected to a first pole of one of the eight drive elements (1, 2) and the output of the ninth half-bridge (5) is connected to all second poles of the eight drive elements (1, 2).
