The subject of this thesis is the application of multibody system techniques for vehicle chassis modelling aimed at the development of integrated vehicle control. This work revised the application of auto­matic control to automotive vehicles and it has observed that most applications to date adopt a piecemeal approach whereby individual vehicle subsystems are treated in isolation. The coordination and integration of automotive vehicle motion control requires that the in­teraction amongst the various subsystems is taken into consideration at the design stage. Integrated vehicle control is then proposed as the motion management concept. A revision about existing techniques for generating the equations of motion for vehicle chassis, using multi­body systems (MBS) techniques is also carried out. It realises that resulting models can be complex and that simplifications in chassis description is recommendable. For this purpose, it has developed a technique for representing suspension geometry effects which by tak­ing the MBS structure into account, results in small and fast runtime simulation models. Yet, the model is capable of describing the full range of normal operation of the automotive vehicle. Using the previ­ously developed model, comprehensive analysis of all aspects of vehicle motion is carried out. The objectives of such analysis is the deter­mination of a driving envelope in which the use of linearised models of the nonlinear chassis can be justified for control analysis and de­sign. Finally, the numerical and control theoretical properties of the linearised models are addressed. State space and transfer function matrix representations are used for such purposes.
