Advanced 3-D trailer pose estimation for articulated vehicles

Abstract

When crafting driver assistance systems designed for truck/trailer combinations, knowledge about the position and orientation of a truck relative to the attached trailer is a vital prerequisite for any kinematic calculation and trajectory estimation. An advanced optical sensor system measuring the 3-D state of an attached two-axle trailer is proposed in this publication. It uses a Kalman filter for enhanced pose estimation and is evaluated against previous versions of the sensor system for the same purpose.
