Nowadays, using advanced vehicle control and safety systems in vehicles is growing rapidly. In this regard, in recent years new control systems, called VDC, have been introduced. These systems stabilize vehicle yaw motion, by yaw moment resulted from tire controlling forces. In this paper, an adaptive optimal controller applied to a vehicle to obtain a satisfactory lateral and yaw stability. To...

Based on the multibody dynamics model of Electric Power Steering System(EPS) and the lateral and longitudinal dynamics vehicle model, the EPS and Anti-lock Braking System (ABS) sub-controllers and the coordination controller are respectively designed according to the motion coupling relation between the steering system and the braking system. The coordination controller supervises and coordinat...

With the benefits of Internet Vehicles (IoV) paradigm, come along unprecedented security challenges. Among many applications inter-connected systems, vehicular networks and smart cars are examples that already rolled out. Smart vehicles not only have connecting their internal components e.g. via Controller Area Network (CAN) bus, but also connected to outside world through road side units other...

Fuzzy logic control is being increasingly applied to solve control problems in areas where system complexity, development time and cost are the major issues. In the absence of a system mathematical model , a fuzzy system model is described which is analogous to a human operator’s behavior, based on approximate reasoning bound by a minimum set of rules. A set of linguistic fuzzy control rules ar...

The paper presents objectives and results of a case study in computer support for failure mode and effects analysis and for the creation of repair manuals in the domain of automotive systems. Model-based prediction and diagnosis reflect the requirements of these tasks. More specifically, qualitative models of system components are necessary for both capturing the available knowledge and achievi...

The paper presents objectives and results of a series of case studies in computer support for diagnosis, failure mode and effects analysis, and the creation of repair manuals in the domain of automotive systems. Model-based prediction and diagnosis reflect the requirements of these tasks. More specifically, qualitative models of system components are necessary for both capturing the available k...

Rapid advances have been made in the field of vehicle dynamics in terms of improving the ride, handling and safety using actuators and control systems. Optimising a vehicle’s ride comfort or handling has led to the development of semi-active suspension systems. Anti-lock braking systems (ABS) have resulted in significant improvements in vehicle braking whilst maintaining directional control ove...

This paper describes an approach of how to estimate the vehicle velocity using additional sensors provided by the brake-by-wire actuators. The advantage of brake-by-wire actuators such as the electro-hydraulic (EHB) and the electro-mechanical brake (EMB) is that the caliper pressure or the clamping force, respectively, are known. Wheel speed, vehicle acceleration, and caliper pressure or clampi...
