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.
Claims8
A distance sensor device, comprising:
- at least one distance sensor, at least one of the at least one distance sensor having at least two different modes of operation;
- and
- a distance sensor control device for activating each of the at least one distance sensor via a respective signal line using an activation pulse, wherein the distance sensor control device is operable to control a switchover between the at least two different modes of operation by varying at least one of a duration and an amplitude of the activation pulse.
