Abstract
A distance sensor device, in particular as a component of a parking aid or reversing aid for a motor vehicle, includes one or more distance sensors and a distance sensor control device for the purpose of activating the distance sensor or sensors via a respective signal line using an activation pulse that is quasi-digital and time-analog. At least one of the distance sensors has two different modes of operation. The modes of operation may be switched by varying the duration and/or amplitude of the activation from the distance sensor control device.
