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 or
wherein, for each signal object thus recognized and classified, at least one allocated signal object parameter and at least one symbol for this signal object are determined; and
determining a chirp value as an allocated signal object parameter which indicates, whether the recognized signal object is an echo of an ultrasonic transmission burst including chirp-up, chirp-down, or no chirp features;
transmitting the at least one symbol of the recognized signal object classes and the at least one allocated signal object parameter of the recognized signal object classes, wherein the at least one signal object parameter includes a signal object parameter indicating the chirp value; and
classifying an object in an environment of the vehicle or determining a distance to an object in the environment of the vehicle based on the transmitted at least one symbol and the at least one allocated signal object parameter.
