Development of a Robust Integrated Control System to Improve the Stability of Road Vehicles

State-of-the-art and challenges of railway and road vehicle dynamics with multibody dynamics approaches

“…Although simple and linear, it still serves as a basis for developing and enhancing control strategies. Today it usually is extended to a four wheel handling model [107] and/or supplemented by a rear wheel steering [40]. It even makes it possible to assess the cornering resistance of vehicles if geometric non-linearities are taken into account [175,178].…”

“…Usually, these models are validated via driving simulators where the real driver is part of the system. Some potentials of integrated control are discussed in [131] and [39,40].…”

“…The sophisticated but quit simple contact calculation, incorporated in TMeasy [179], makes it even possible to simulate the instabilities of trucks running along track-grooves [94]. Modern control devices that react also in critical driving situations, like ABS, ESP, or Steer-by-Wire (SBW), demand for sufficiently accurate vehicle models in order to develop and enhance this systems [228] and [40]. To master this challenge, commercial or 'handmade' multibody system models are predestinated because they represent an excellent compromise between computation effort and accuracy.…”
