Method for carrying out an at least partly automated driving function utilizing infrastructure as a control input

A device including a control unit and at least one communication interface, the device configured to:

• determine that an infrastructure element is located in an environment of the motor vehicle, the infrastructure element being configured to determine an infrastructure assistance datum for an infrastructure-based, at least partly automated guidance of the motor vehicle, wherein the infrastructure element is part of an event chain for the at least partly automated guidance of the motor vehicle during a trip that is guided in an at least partly automated manner;
• determine a minimum safety integrity level that the event chain must have for the infrastructure assistance datum of the infrastructure element to be used by the motor vehicle to carry out the at least partly automated driving function;
• determine which safety integrity level the event chain maximally fulfills;
• determine, based on the minimum safety integrity level and the maximum safety integrity level of the event chain, whether the at least partly automated driving function may be carried out based on the infrastructure assistance datum of the infrastructure element;
• carry out the at least partly automated driving function based on the infrastructure assistance datum and depending on a result of the determination as to whether the at least partly automated driving function may be carried out based on the infrastructure assistance datum of the infrastructure element,
• wherein the infrastructure element includes a video camera configured to capture an image of the environment of the motor vehicle and to generate the infrastructure assistance datum based on the captured image.

A non-transitory machine-readable storage medium on which is stored a computer program for carrying out a partly automated driving function by a motor vehicle, the computer program, when executed by a computer, causing the computer to perform the following steps:

• determining that an infrastructure element is located in an environment of the motor vehicle, the infrastructure element being configured to determine an infrastructure assistance datum for an infrastructure-based, at least partly automated guidance of the motor vehicle, wherein the infrastructure element is part of an event chain for the at least partly automated guidance of the motor vehicle during a trip that is guided in an at least partly automated manner;
• determining a minimum safety integrity level that the event chain must have for the infrastructure assistance datum of the infrastructure element to be used by the motor vehicle to carry out the at least partly automated driving function;
• determining which safety integrity level the event chain maximally fulfills;
• determining, based on the minimum safety integrity level and the maximum safety integrity level of the event chain, whether the at least partly automated driving function may be carried out based on the infrastructure assistance datum of the infrastructure element;
• carrying out the at least partly automated driving function based on the infrastructure assistance datum and depending on a result of the determination as to whether the at least partly automated driving function may be carried out based on the infrastructure assistance datum of the infrastructure element,
• wherein the infrastructure element includes a video camera configured to capture an image of the environment of the motor vehicle and to generate the infrastructure assistance datum based on the captured image.
