Method and device for determining a quality value of a parking space

A method for determining a quality value of a parking space, the method comprising:

• determining an accessible area of the parking space;
• defining grid points in the accessible area;
• determining features of the parking space for each of the grid points, wherein each of the features is registrable from a respective one of the grid points;
• and
• obtaining the quality value from an average number of features that is registrable from each of the grid points,
• wherein, the obtaining the quality value is based on:
• a variance in a number of features that is registrable from each grid point, or
• a current occupancy status of the parking space.

A method for navigating a motor vehicle, the method comprising:

• determining a first quality value of a first parking space by:
• determining a first accessible area of the first parking space;
• defining first grid points in the first accessible area;
• determining first features of the first parking space for each of the first grid points, wherein each of the first features is registrable from a respective one of the first grid points;
• and
• obtaining the first quality value from an average number of first features that is registrable from each of the first grid points;
• checking whether the first quality value meets a first condition;
• and
• in response to determining that the first quality value meets the first condition, navigating the motor vehicle into the first parking space or releasing the first parking space for the motor vehicle.

A device for determining a quality value of a parking space, the device comprising:

• a first sensor device that, in operation, determines an accessible area of the parking space;
• a processor that, in operation, defines grid points in the accessible area;
• a second sensor device that, in operation, determines, for each of the grid points, features of the parking space that are registrable from a respective one of the grid points;
• and
• a computing device that, in operation, obtains the quality value from an average number of features that is registrable from each of the grid points,
• wherein, to determine the features, the second sensor device:
• obtains either polar coordinates or Cartesian coordinates of each of the features in relation to the respective one of the grid points, or
• for each feature of the features, provides information via one of several detector technologies with which the feature is registrable from the respective one of the grid points, and provides the quality value for one or more of the detector technologies.

A device for navigating a motor vehicle with autonomous or semi-autonomous steering, the device comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor causes the device to:
• determine an accessible area of a parking space;
• define grid points in the accessible area;
• determine features of the parking space for each of the grid points, wherein each of the features is registrable from a respective one of the grid points;
• obtain a quality value from an average number of features that is registrable from each of the grid points;
• and
• drive the motor vehicle based on the quality value,
• wherein, to determine the features, the processor:
• obtains either polar coordinates or Cartesian coordinates of each of the features in relation to the respective one of the grid points, or
• for each feature of the features, provides information via one of several detector technologies with which the feature is registrable from the respective one of the grid points, and provides the quality value for one or more of the detector technologies.
