A vehicle radar detection system arranged to be mounted in an ego vehicle and including at least one detector arrangement and at least one control unit arrangement. The detector arrangement is adapted to obtain a dataset initially including a number K of radar detections. The control unit arrangement is adapted to repeatedly determine a dominating line from the dataset of radar detections, remove radar detections associated with the dominating line from the dataset of radar detections until a first stopping criterion is fulfilled, thereby determining a plurality of lines from the number K of radar detections.

Detecting a parking row with a vehicle radar system

A sensor signal processing unit () arranged to detect a configuration of parking slots () based on radar detections received from a radar-based sensor system (). The unit includes a histogram unit arranged to generate a representation of a spatial distribution of a set of radar detection coordinates, and a detection unit arranged to detect the configuration of parking slots. The detection unit is arranged to detect the configuration of parking slots based on a Fourier transform of the representation of spatial distribution.

Detection of parking slot configuration based on repetitive patterns

A vehicle environmental detection system () in an ego vehicle () and having at least one detector arrangement () and at least one control unit arrangement () configured to determine a slant angle of parking slots in a parking row. The detector arrangement () is adapted to obtain a set of detections (d(k), k=1 . . . K). For each slant angle (&#x3b1;) in a set of slant angles (&#x3b1;, n=1 . . . N), the control unit arrangement () is adapted to calculate a set of slant rotated detections (d(k, &#x3b1;), k=1 . . . K) by rotating coordinates of each detection in the set of detections (d(k), k=1 . . . K)) by the present slant angle (&#x3b1;), calculate a projection profile (P(&#x3b1;)) for the set of slant rotated detections (d(k,&#x3b1;), k=1 . . . K) by determining a histogram of slant rotated detection coordinates, and to calculate an entropy (H(&#x3b1;)) associated with the calculated projection profile (P(&#x3b1;)). The control unit arrangement () can determine the slant angle based on the calculated entropies (H(&#x3b1;), n=1 . . . N).

Detection of parking row orientation

A vehicle environmental detection system () in an ego vehicle () including at least one control unit arrangement () and at least one detector arrangement () that is adapted to obtain a plurality of detections (). The control unit arrangement () is adapted to form a cluster () of the plurality of detections (), form a first border line () and a second border line (), where these border lines () have mutually longitudinal extensions, and are mutually parallel and define outer borders of the cluster () and determine whether the cluster () corresponds to a row () of corresponding parked vehicles (), by the length or longitudinal displacement of, or distance between, the border lines ().

Vehicle environmental detection system for parking detection

A method and a system () for detecting parking spaces () suitable for a vehicle (). In order to determine a parking space (), radar signals () are directed to a plurality of vehicles () parked in a parking area () and also to surrounding elements (). The radar signals () reflected by the parked vehicles () and also the surrounding elements () are processed in a computing unit (). A gap () in a calculated periodicity () of a projection profile () is determined with an autoregressive prediction filter (). A prediction error function () has the highest value () at the location of a parking space ().
