About this book

This monograph focuses on control methods that influence vehicle dynamics to assist the driver in enhancing passenger comfort, road holding, efficiency and safety of transport, etc., while maintaining the driver’s ability to override that assistance. On individual-vehicle-component level the control problem is formulated and solved by a unified modelling and design method provided by the linear parameter varying (LPV) framework. The global behaviour desired is achieved by a judicious interplay between the individual components, guaranteed by an integrated control mechanism. The integrated control problem is also formalized and solved in the LPV framework. Most important among the ideas expounded in the book are:

application of the LPV paradigm in the modelling and control design methodology;

application of the robust LPV design as a unified framework for setting control tasks related to active driver assistance;

formulation and solution proposals for the integrated vehicle control problem;

proposal for a reconfigurable and fault-tolerant control architecture;

formulation and solution proposals for the plug-and-play concept;

detailed case studies.

Robust Control Design for Active Vehicle Assistance Systems will be of interest to academic researchers and graduate students interested in automotive control and to control and mechanical engineers working in the automotive industry.

Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

Chapter 1. Introduction
Abstract
Active driver assistance systems are able to assist the driver in enhancing passenger comfort, road holding, the efficiency and safety of transport, etc. At the same time, the responsibility remains with the driver since the driver is able to override the assistance. The demand for vehicle control methodologies that include the driver, the vehicle, and the road arises at several research centers and automotive suppliers.

Modeling and Control of LPV Systems

Frontmatter
Chapter 2. Modeling of LPV Systems
Abstract
In general terms, control theory can be described as the study of how to design the process of influencing the behavior of a physical system to achieve a desired goal.

Chapter 3. Robust Control of LPV Systems
Abstract
LPV control synthesis is a controller design approach based on either LPV or LPV LFT which yields parameter-dependent controllers with a priori guaranteed stability and performance properties.

Vertical and Longitudinal Control

Frontmatter
Chapter 4. Suspension Systems in Vertical Dynamics
Abstract
This section is concerned with designing the dynamic properties of vehicle suspension systems to improve the dynamic properties of vehicles. The performance of suspension systems can be assessed quantitatively in terms of four parameters: passenger comfort, suspension deflection, tire load variation, and energy consumption, see Gillespie (1992), Cole (2001). Vehicle vibrations excited by road irregularities might lead to the fatigue of the driver and passengers, as well as damage to the vehicle and the payload. It is widely accepted that there is a correlation between passenger comfort (or ride comfort) and the heave, pitch, and roll accelerations of the sprung mass.

Chapter 5. Anti-roll Bars for Rollover Prevention
Abstract
The aim of rollover prevention is to provide the vehicle with an ability to resist overturning moments generated during cornering. The problem with heavy vehicles in terms of roll stability is a relatively high mass center and narrow track width. When the vehicle is changing lanes or trying to go round obstacles, the vehicle body rolls out of the bend and the center of mass shifts out of the centerline, and a destabilizing moment is created.

Chapter 6. Adaptive Cruise Control in Longitudinal Dynamics
Abstract
In the last decade, the longitudinal vehicle control based on the look-ahead approach has been in the focus of the automotive research centers.

Lateral and Integrated Control

Chapter 7. Design of Integrated Vehicle Control
Abstract
Conventionally, the control systems of vehicle functions to be controlled are designed separately by the suppliers and the vehicle companies.

Chapter 8. Control of the Variable-Geometry Suspension
Abstract
A variable-geometry suspension system is applied as a driver assistance system in vehicles. While the driver performs a maneuver using the steering wheel, an autonomous control system modifies the camber angle of the front wheels in order to improve road stability. Since various safety and economy properties of the vehicle are determined by the suspension geometry it has significant influence on the control design.

Chapter 9. Control Design of In-Wheel Motors
Abstract
The growing need of economical and environmentally sound road vehicles enhances the attention of researchers and car makers towards electric vehicles. Within this segment of alternative transportation tools in-wheel electric vehicles using hub motors integrated inside the wheels have several advantages compared to conventional electric vehicles.

Chapter 10. Driver Models in the Control Systems
Abstract
The integrated control proposed in the paper is based on a supervisory integrated structure in which the control components are designed independently.
