1. A method for transmitting sensor data, from a sensor to computer system in a vehicle, comprising:
emitting an ultrasonic burst;
receiving an ultrasonic signal and forming an ultrasonic reception signal;
forming a feature vector signal from the ultrasonic reception signal;
recognizing signal objects and classifying the signal objects in recognized signal object classes within the ultrasonic reception signal based on the feature vector signal;
wherein, to each signal object thus recognized and classified, at least one allocated signal object parameter and at least one symbol are allocated corresponding to the recognized signal object classes allocated to this signal object; and
transmitting the at least one symbol of some of at least two or more of the recognized signal object classes and the at least one allocated signal object parameter of the some of at least two or more of the recognized signal object classes;
wherein the transmission of the at least one symbol of the some of at least two or more recognized signal object classes and the at least one allocated signal object parameter of the some of at least two or more signal object classes includes a transmission of a signal object class of a signal object including a predefined temporal sequence of two or more other signal objects, and
wherein a symbol of one signal object class of at least one of the two or more other signal objects is omitted from the transmission.
