This paper presents a sensor platform to measure the forces acting on a semi-trailer fifth wheel (kingpin). All parts of the measurement chain are taken from a commercially available wheel force transducer. Adapters to the semitrailer and a replacement kingpin are designed and build as prototypes. Basic load assumptions are made to dimension the parts. The sensor platform is calibrated on a wheel force transducer test rig to ensure accuracy and stability against the attacking forces. During a measurement campaign with a semi-trailer typical maneuvers like acceleration, braking, lane change, rough road, etc. are measured. Time series data of the maneuvers and spectra of public road driving are shown. The outlook gives a view on how the measurement data are used to validate multi body simulation models of the semi-trailer. Using those models, different properties of the trailer are predicted like center of gravity position, rolling gear and tire characteristics. Furthermore, condition monitoring of trailer components is part of the modelling to prepare the trailer for autonomous driving applications.
