Abstract
The invention relates to an ultrasonic sensor () for use in a distance detection system () for a vehicle (), wherein the ultrasonic sensor () is designed to be installed jointly with at least one other ultrasonic sensor (), the ultrasonic sensor () has a first input () for connection to a supply lead (), the ultrasonic sensor () has a second input () for connection to a ground potential () of the vehicle (), and the ultrasonic sensor () has an output () for connection to the supply lead (), wherein the ultrasonic sensor () is designed to receive a data signal modulated on the supply lead () via the first input () and to modulate a data signal onto the supply lead () via the output (). The invention also relates to a distance detection system () for a vehicle () having a plurality of the above ultrasonic sensors (), wherein the ultrasonic sensors () are connected to each other in the form of a chain, the output () of a preceding ultrasonic sensor () being connected to the first input () of a subsequent ultrasonic sensor (), a first ultrasonic sensor () in the chain is connected with its first input () to a supply voltage (), and a final ultrasonic sensor () in the chain is connected with its output () to a signalling unit ().
