Abstract
A method for determining kinematics of a target includes generating a measured trace of a target position, speed, and angle of a target relative to an ego vehicle. The radius of the curve that the target is taking is calculated, using the generated trace. A number of paths possible to be followed by the target are projected, expressed as abstract movement functions of a polynomial degree and using as input the calculated radius. At each further cycle, higher probabilities are added to the paths projected in a previous measuring cycle which are equal with the newly projected ones. The projected paths are kept if the radius remains the same as in the previous measuring cycle. The current kinematics values are computed by smoothing filtering as predicted kinematics values, which are compared with the kinematics values resulted from the projected paths, to determine the final kinematics values.
