Method for classifying a relevance of an object

A device for a motor vehicle that includes an environmental sensor, the device configured to:

• receive measurement signals that represent:
• a radial distance, measured by the environmental sensor, of an object, that is situated in a surrounding environment of the motor vehicle, relative to the environmental sensor;
• a radial relative velocity, measured by the environmental sensor, of the object relative to the environmental sensor;
• and
• a measured own velocity of the motor vehicle;
• calculate, based on the received measurement signals, a location uncertainty value that indicates an item of location information of possible locations of the object;
• receive dimension signals that represent dimensions of the motor vehicle;
• calculate a threshold value based on the received dimension signals;
• compare the location uncertainty value with the threshold value;
• as a function of the comparison, calculate whether the motor vehicle can collide with the object;
• and
• output a result signal that represents a result of the calculation of whether the motor vehicle can collide with the object.

A non-transitory machine-readable storage medium on which is stored a computer program for a motor vehicle that includes an environmental sensor, the computer program being executable by a computer and, when executed by the computer, causing the computer to perform the following steps:

• receiving measurement signals that represent:
• a radial distance, measured by the environmental sensor, of an object, that is situated in a surrounding environment of the motor vehicle, relative to the environmental sensor;
• a radial relative velocity, measured by the environmental sensor, of the object relative to the environmental sensor;
• and
• a measured own velocity of the motor vehicle;
• calculating, based on the received measurement signals, a location uncertainty value that indicates an item of location information of possible locations of the object;
• receiving dimension signals that represent dimensions of the motor vehicle;
• calculating a threshold value based on the received dimension signals;
• comparing the location uncertainty value with the threshold value;
• as a function of the comparison, calculating whether the motor vehicle can collide with the object;
• and
• outputting a result signal that represents a result of the calculation of whether the motor vehicle can collide with the object.
