Device for infrastructure-supported assistance of a motor vehicle

A method for infrastructure-supported assistance of a motor vehicle, using a device including:

• a communication device configured to receive surroundings signals that represent surroundings of the motor vehicle, and
• a processor device configured to ascertain, based on the surroundings signals, infrastructure assistance data for infrastructure-supported assistance of the motor vehicle;
• wherein the communication device is configured to send infrastructure assistance data signals that represent the ascertained infrastructure assistance data,
• the method comprising the following steps:
• receiving, using the communication device, the surroundings signals that represent the surroundings of the motor vehicle;
• ascertaining, using the processor device, the infrastructure assistance data for infrastructure-supported assistance of the motor vehicle, based on the surroundings signals;
• sending, using the communication device, infrastructure assistance data signals that represent the ascertained infrastructure assistance data;
• wherein each of the communication device and the processor device is configured to continue operating in an event of an error, in such a way that the communication device continues to receive the surroundings signals, the processor device continues to ascertain, based on the surroundings signals, the infrastructure assistance data for infrastructure-supported assistance of the motor vehicle, and the communication device continues to send the infrastructure assistance data signals,
• wherein the processor device is further configured to ascertain a criticality of a present or a predicted traffic situation, the criticality indicating at least one of a potential accident location, an involved vehicle, or a timing of a potential accident, and wherein the infrastructure assistance data are further ascertained based on the criticality to initiate accident avoidance measures.

A non-transitory machine-readable memory medium on which is stored a computer program for infrastructure-supported assistance of a motor vehicle, using a device including:

• a communication device configured to receive surroundings signals that represent surroundings of the motor vehicle, and
• a processor device configured to ascertain, based on the surroundings signals, infrastructure assistance data for infrastructure-supported assistance of the motor vehicle;
• wherein the communication device is configured to send infrastructure assistance data signals that represent the ascertained infrastructure assistance data,
• the computer program, when executed by a computer, causing the computer to perform the following steps:
• receiving, using the communication device, the surroundings signals that represent the surroundings of the motor vehicle;
• ascertaining, using the processor device, the infrastructure assistance data for infrastructure-supported assistance of the motor vehicle, based on the surroundings signals;
• sending, using the communication device, infrastructure assistance data signals that represent the ascertained infrastructure assistance data;
• wherein each of the communication device and the processor device is configured to continue operating in an event of an error, in such a way that the communication device continues to receive the surroundings signals, the processor device continues to ascertain, based on the surroundings signals, the infrastructure assistance data for infrastructure-supported assistance of the motor vehicle, and the communication device continues to send the infrastructure assistance data signals,
• wherein the processor device is further configured to ascertain a criticality of a present or a predicted traffic situation, the criticality indicating at least one of a potential accident location, an involved vehicle, or a timing of a potential accident, and wherein the infrastructure assistance data are further ascertained based on the criticality to initiate accident avoidance measures.
