Samsung patents radar method to predict cut-in vehicles using wheel motion

Patent drawing
Patent drawing from the official filing.

This patent describes a method for car radar systems to predict how a vehicle will move when it cuts into your lane. It works by isolating the specific speed of the other car's wheels from the radar data to calculate its exact position and direction more accurately.

Why it mattersThis could make driver-assistance systems more reliable by helping cars anticipate sudden lane changes from nearby vehicles.

In the filing’s own words

A method of predicting a movement of a cut-in object, including separating a Doppler velocity corresponding to at least one wheel of the cut-in object from radar data based on a velocity of the cut-in object, determining a position of the at least one wheel of the cut-in object based on the Doppler velocity, generating at least one of first movement information related to a horizontal movement of the cut-in object or second movement information related to a moving direction of the cut-in object based on the position of the at least one wheel, and determining a position of the cut-in object based on at least one of the first movement information or the second movement information.

What exactly they claim (claim 1)

1. A processor-implemented method of predicting a movement of a cut-in object, the method comprising: Identifying a region where the cut-in object is positioned; generating a plurality of points in a first coordinate system based on distance, direction of arrival (DOA), and velocity corresponding to the region, the plurality of points being determined from radar data; determining a first velocity of the cut-in object by transforming the plurality of points of the first coordinate system into a second coordinate system based on time, frequency, and the velocity corresponding to the region; separating a second velocity being a Doppler velocity corresponding to at least one wheel of the cut-in object from the second coordinate system based on the first velocity of the cut-in object; determining at least one position of the at least one wheel of the cut-in object based on the points corresponding to the second velocity among the plurality of points of the first coordinate system; generating at least one of first information related to a movement of the cut-in object or second information related to a direction of the cut-in object based on the at least one position of the at least one wheel; determining an estimated position of the cut-in object based on at least one of the first information or the second information; and controlling a driving vehicle based on the estimated position of the cut-in object, wherein the identifying of the region of the cut-in object is performed before the separating of the second velocity.
