Using models to validate vehicle-trailer stabilisation

This article describes the use of a software product, Tesis Vedyna, in the development and testing of vehicle dynamics controllers. German brake system manufacturer Knott employed the software to validate and pre-calibrate the stability control for trailers or towed vehicles. The electronic trailer stabilisation (ETS) system involves an electronically controlled stabilisation ball joint to produce a friction torque, and a hydraulic brake system. Vedyna is a tailored vehicle dynamics programme for fast simulation on PC platforms, combining high-precision models with efficient numerical solvers. It allows various coupling types to be depicted precisely. The vehicle models used are implemented in Matlab and Simulink, providing the flexibility to replace single components or to include user-defined interfaces. Encapsulation of the control system in a separate s-function enables reusability of the simulation model. The vehicle states required for detecting the swaying motion, and other variables, are exchanged via connecting lines. Simulation results show the effectiveness of the ETS in improving the stability of the vehicle-trailer combination, damping the swaying motion and preserving controllability. Comparison with field test measurements shows an acceptable level of accuracy.
