direction of the ISO 8855 [[21]](#references) coordinate system centered on the trailer) and the direction of
the segment having as end points the reference point of the trailer and the reference point of
the pulling vehicle, which can be another trailer or a vehicle looking on the horizontal plane
xy, described in the local Cartesian coordinate system of the trailer. The
angle is measured with negative values considering the trailer orientation turning clockwise
starting from the segment direction. The angle value accuracy is provided with the
confidence level of 95 %.
