The invention relates to a circuit for selectively actuating drive elements (), which are operated on direct current, in a motor vehicle by means of half-bridges (). According to the invention, the circuit is designed for selectively actuating eight drive elements () 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 (), wherein the outputs of eight of the nine half-bridges () are each connected to a first pole of one of the eight drive elements () and the output of the ninth half-bridge () is connected to all second poles of the eight drive elements ().

The disclosure relates to a method and an apparatus to secure a system for passive unlocking of a vehicle system, particularly a vehicle unlocking system, against relay station attacks. The system comprises a vehicle-based device that can send on a first radio frequency and receive on a second radio frequency, and a driver-based device that can receive on the first radio frequency and send on the second radio frequency. The vehicle-based device and/or the driver-based device are also able to receive on a radio frequency that the other device can receive. One of the two devices send at least one ambient noise signal sequence to the other device. The ambient noise signal sequences received by both are compared with one another with cross-correlation. A current situation is deemed safe if the cross-correlation is strong and a phase shift is small.
