Disclosed is an arrangement and a method for hitch-angle estimation for a tractor-trailer combination. The arrangement comprising one or more sensors for providing one or more point clouds comprising a representation for the trailer as seen from one or more measurement positions at the tractor, a first measurement for the speed of the tractor, and a second measurement for an orientation of the tractor. The arrangement also comprises a computing unit configured to obtain one or more first values indicating the hitch angle between the tractor and the trailer, determined from the one or more point clouds, obtain a second value indicating the rate of change for the hitch angle, determined from the first and the second measurement, and fuse the one or more first values and the second value to provide an estimate for the hitch angle between the tractor and the trailer.
