10. An ultrasonic sensor system for a motor vehicle, comprising:
a plurality of transmitters of a plurality of ultrasonic sensors which are configured to emit respective ultrasonic signals, wherein the ultrasonic signals each comprises a sequence of elementary signals, wherein the elementary signals have signal pauses and a plurality of different signal pulses, and wherein the ultrasonic signals of various transmitting devices of the plurality of transmitting devices differ from one another by the sequence of the elementary signals;
at least one receiver of the ultrasonic sensors which is configured to receive reflected ultrasonic signals; and
at least one evaluation device comprising at least one processor circuit which is configured to associate the received ultrasonic signals with the emitted ultrasonic signals on the basis of the sequences of the elementary signals,
wherein each elementary signal comprises a pause, a first signal pulse or a second signal pulse, the ultrasonic sensors comprise a first ultrasonic sensor that emits first ultrasonic signals and a second ultrasonic sensor that emits second ultrasonic signals, the first and second emitted ultrasonic signals comprising at least a part of the plurality of emitted ultrasonic signals, the first ultrasonic signal emitted comprises a sequence of the elementary signals that is distinct relative to the sequence of the elementary signals of the second ultrasonic signal emitted, and the association of each received ultrasonic signal with one emitted ultrasonic signal of the plurality of emitted ultrasonic signals is based on the sequence of the pause elementary signal, the first signal pulse elementary signal and the second signal pulse elementary signal forming the received ultrasonic signal.
