    This paper describes the application of a range of simulation and design techniques to the development of a prototype active suspension system using a novel actuation technique within tight cost and time constraints. The suspension system is centred around a buckling leaf spring element with a very low effective spring rate. This is connected between the body and suspension using a variable geomet...

  • Design concepts and details for an active roll control systems

    Active roll control is a cost effective approach to conventional suspension enhancement. A general active suspension can allow good low frequency vibration isolation and can eliminate body roll and pitch in (low frequency) manoeuvring. However, it is doubtful if car users can discern modest vibration isolation improvements, since they are not sufficiently in touch with the excitation which gives r... View full abstract»

    Observer technology offers substantial scope to improve engine control system performance. Improved control response, the creation of “virtual” sensors and fault detection and diagnosis are all functional improvements which are offered. A simple fault detection function is a proven concept on a turbocharged diesel engine. Control system observers have an appearance of being complex and... View full abstract»

    A variable structure control system (VSCS) may be used to provide robust control of uncertain, often nonlinear, dynamical systems which are subject to external disturbances. The method has thus received some attention from sections of the automotive industry where nonlinear behaviour is common, the operating environment is harsh and tight performance specifications are often required. This paper f... View full abstract»

    Neural networks have been employed in a range of automotive modelling and control tasks. This paper discusses the recently introduced local model network structure. The structure can be viewed as a hybrid model which smoothly combines local models (of linear or nonlinear form) by interpolation. Interpolation of local models is implemented in the form of a basis-function network. The benefits of th... View full abstract»

    The availability of low cost rugged microelectronics has enabled automotive control systems to rapidly advance from hydro-mechanical and simple electro-mechanical implementations to sophisticated computer based systems. These are usually developed as individual subsystems with limited interaction between sub-systems. The current challenge for the automotive control engineer is to address the probl...

    This paper reports on aspects of ongoing work to establish the potential of alternatives to rule-based traction control schemes. The paper is concerned primarily with the modelling and control of a brake intervention system. Control theory objectives have led to the development of a full nonlinear MATRIXx simulation model as the test bed to evaluate the performance of different control approaches View full abstract»
