Abstract
A method for ascertaining emissions of a motor vehicle driven with the aid of an internal combustion engine in a practical driving operation. A machine learning system is trained to generate time curves of the operating variables with the aid of measured time curves of operating variables of the motor vehicle and/or of the internal combustion engine, and to then ascertain the emissions as a function of these generated time curves.
Claims21
A computer-implemented method for ascertaining emissions of a motor vehicle driven using an internal combustion engine in a driving operation, the method comprising the following steps:
- training a machine learning system to generate time curves, of operating variables of the internal combustion engine and/or of the motor vehicle, using measured time curves of the operating variables of the internal combustion engine and/or of the motor vehicle;
- generating, by the machine learning system, the time curves of the operating variables;
- ascertaining the emissions as a function of the generated time curves generated by the machine learning system;
- and
- controlling the motor vehicle as a function of the ascertained emissions.
A non-transitory machine-readable memory medium on which is stored a computer program for ascertaining emissions of a motor vehicle driven using an internal combustion engine in a driving operation, the computer program, when executed by a computer, causing the computer to perform the following steps:
- training a machine learning system to generate time curves, of operating variables of the internal combustion engine and/or of the motor vehicle, using measured time curves of the operating variables of the internal combustion engine and/or of the motor vehicle;
- generating, by the machine learning system, the time curves of the operating variables;
- ascertaining the emissions as a function of the generated time curves generated by the machine learning system;
- and
- controlling the motor vehicle as a function of the ascertained emissions.
A computer configured to ascertain emissions of a motor vehicle driven using an internal combustion engine in a driving operation, the computer configured to:
- train a machine learning system to generate time curves, of operating variables of the internal combustion engine and/or of the motor vehicle, using measured time curves of the operating variables of the internal combustion engine and/or of the motor vehicle;
- generate, by the machine learning system, the time curves of the operating variables;
- ascertain the emissions as a function of the generated time curves generated by the machine learning system;
- and
- control the motor vehicle as a function of the ascertained emissions.
