Abstract
The invention relates to a method for operating ultrasonic sensors) for a motor vehicle, including emitting a plurality of ultrasonic signals by respective ultrasonic sensors. The ultrasonic signals include a sequence of elementary signals. The elementary signals have signal pauses and a plurality of different signal pulses. The ultrasonic signals differ from one another by the sequence of the elementary signals. The method further includes receiving reflected ultrasonic signals, wherein the received ultrasonic signals are associated with the emitted ultrasonic signals on the basis of the sequences of the elementary signals.
Claims15
A method for operating ultrasonic sensors for a motor vehicle, comprising the steps of:
- emitting a plurality of ultrasonic signals by respective ultrasonic sensors, wherein the ultrasonic signals comprise a sequence of elementary signals, wherein the elementary signals have signal pauses and a plurality of different signal pulses, and wherein the ultrasonic signals differ from one another by the sequence of the elementary signals;
- and
- receiving reflected ultrasonic signals, wherein the received ultrasonic signals are associated with the emitted ultrasonic signals on the basis of the sequences of the elementary signals.
An ultrasonic sensor system for a motor vehicle, comprising:
- a plurality of transmitting devices which are configured to emit respective ultrasonic signals, wherein the ultrasonic signals comprise 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 device which is configured to receive reflected ultrasonic signals;
- and
- at least one evaluation device which is configured to associate the received ultrasonic signals with the emitted ultrasonic signals on the basis of the sequences of the elementary signals.
