Method for the semi-automated guidance of a motor vehicle

A device configured for safe, at least semi-automated guidance of a motor vehicle, supported by an infrastructure, the device configured to:

• during the infrastructure-supported, at least semi-automated guidance of the motor vehicle:
• generate control signals for at least semi-automated control of a lateral guidance and/or longitudinal guidance of the motor vehicle without infrastructure support,
• check a functionality of a support by the infrastructure for an at least semi-automated guidance of the motor vehicle, wherein the check of the functionality includes using the generated control signals without infrastructure support to check infrastructure data, which is provided by the infrastructure, for plausibility and/or correctness,
• terminate the infrastructure-supported, at least semi-automated guidance of the motor vehicle depending on a result of the checking, wherein when a temporary limitation is detected, the infrastructure-supported, at least semi-automated guidance of the motor vehicle is not terminated;
• and
• output control signals to guide the motor vehicle in at least semi-automated fashion based on the generated control signals, without the support by the infrastructure,
• wherein the control signals are generated in such a way that based on the output control signals, the motor vehicle:
• (i) is guided in at least semi-automated fashion in a restricted driving mode in which only a limited range of functions in terms of the at least semi-automated guidance is made available, or (ii) is guided in at least semi-automated fashion in a non-restricted driving mode in which a full range of functions in terms of the at least semi-automated guidance is made available, wherein a distance to an object located in front of the motor vehicle in the direction of travel of the motor vehicle is greater in the restricted driving mode than in the non-restricted driving mode.

A non-transitory machine-readable storage medium on which is stored a computer program for safe, at least semi-automated guidance of a motor vehicle, supported by an infrastructure, the computer program, when executed by a computer, causing the computer to perform the following steps:

• during the infrastructure-supported, at least semi-automated guidance of the motor vehicle:
• generating control signals for at least semi-automated control of a lateral guidance and/or longitudinal guidance of the motor vehicle without infrastructure support,
• checking a functionality of a support by the infrastructure for an at least semi-automated guidance of the motor vehicle, wherein the checking the functionality includes using the generated control signals without infrastructure support to check infrastructure data, which is provided by the infrastructure, for plausibility and/or correctness,
• terminating the infrastructure-supported, at least semi-automated guidance of the motor vehicle depending on a result of the checking, wherein when a temporary limitation is detected, the infrastructure-supported, at least semi-automated guidance of the motor vehicle is not terminated;
• and
• outputting control signals to guide the motor vehicle in at least semi-automated fashion based on the generated control signals, without the support by the infrastructure,
• wherein the control signals are generated in such a way that based on the output control signals, the motor vehicle:
• (i) is guided in at least semi-automated fashion in a restricted driving mode in which only a limited range of functions in terms of the at least semi-automated guidance is made available, or (ii) is guided in at least semi-automated fashion in a non-restricted driving mode in which a full range of functions in terms of the at least semi-automated guidance is made available, wherein a distance to an object located in front of the motor vehicle in the direction of travel of the motor vehicle is greater in the restricted driving mode than in the non-restricted driving mode.
