Abstract: A device and a method determine sensor positions of sensor units of a driver assistance system, especially a parking aid system of a vehicle. The sensor units each have a plurality of terminals of different identification positions. A data bus is connected for an exchange of data with a central control and evaluation unit in this case with one or more terminals of the sensor unit according to a specific connection scheme, which is different for each of the sensor units, in order to provide an identity code for the sensor position of a sensor unit in this way.

Abstract: The invention relates to a method for overload-free driving of an actuator, in which an activation counter is incremented or decremented each time an activation request signal occurs, in which, depending on each occurrence of an activation request signal, a drive signal for the actuator is generated if the counter reading of the activation counter is less than or greater than a predetermined maximum or minimum counter reading, in which the counter reading is in each case decremented or incremented if the time since the last generation of a drive signal or since the deactivation of the drive signal is greater than or equal to a predetermined or predeterminable interval time or if the time since the last decrementing of the activation counter is greater than or equal to the interval time.
