Transmitting ultrasonic signal data

A method for transmitting sensor data from a sensor to a computer system in a vehicle, the method comprising:

• emitting an ultrasonic burst;
• receiving an ultrasonic signal and forming an ultrasonic reception signal including a sequence of sample values, wherein a temporal date is allocated to each of the sample values in the sequence of sample values;
• determining a first parameter signal of a feature using a first filter from the sequence of the sample values, wherein the first parameter signal is configured as a time-discrete sequence of first parameter signal values, and wherein exactly one temporal date is allocated to each of the first parameter signal values;
• determining at least one further parameter signal of the feature using a further filter from the sequence of sample values of the reception signal, wherein the at least one further parameter signal is configured as time-discrete sequence of further parameter signal values, wherein the same temporal date that is allocated to each of the first parameter signal values is also allocated to each of the further parameter signal values corresponding with the respective first parameter signal values;
• wherein, hereinafter, the first parameter signal and the at least one further parameter signal are referred to together as a feature vector signal;
• wherein the feature vector signal is thus configured as a time-discrete sequence of parameter vector signal values, also referred to hereinafter as feature vector signal values, formed by the first parameter signal values and the at least one further parameter signal values, each with the same respective temporal date;
• and
• wherein the respective temporal date is allocated to each feature vector signal value thus formed;
• comparing the feature vector signal values of a temporal date to a threshold value vector while forming a Boolean result which may take one of a first Boolean value and a second Boolean value;
• transmitting the feature vector signal values and the temporal date allocated to the feature vector signal value from the sensor to the computer system, if the Boolean result for the temporal date takes the first Boolean 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 feature vector signal values.

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, a signal object comprises a combination of two or more basic signal objects;
• 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;
• 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 class;
• 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.
