For each automotive control problem considered, the authors emphasize the physics and underlying principles behind the control system concept and design. This is an exciting and rapidly developing field for which many articles and reports exist but no modern unifying text. An extensive list of references is provided at the end of each chapter for all the topics covered. It is currently the only textbook, including problems and examples, that that covers and integrates the topics of automotive powertrain control, vehicle control, and intelligent transportation systems. The emphasis is on fundamental concepts and methods for automotive control systems, rather than the rapidly changing specific technologies. Many of the text examples, as well as the end-of-chapter problems, require the use of MATLAB and/or SIMULINK.

The distinguishing feature is the treatment of the control design model as a degree of design freedom. A simple example highlights the potential improvement in closed-loop performance under the coupled approach. Quantification of the strength of the coupling in terms of performance boundaries is also described

A radially rotating flexible beam attached to a rigid shaft is considered. Both experimental and numerical studies are undertaken. Experimental studies how excellent agreement with simulation studies using both the momentum balance (coefficient of friction), and spring-dashpot (impact pair) models. The simulation studies are even capable of predicting the high-speed multiple impacts which occur due to structural flexibility and which are experimentally observed using high-speed video photography. The results of the studies show that a simple momentum balance (coefficient of restitution) method for simulating the impact is sufficiently accurate in predicting the dynamic behavior of the system for most engineering applications. The momentum balance method cannot simulate the impact force which develops during the contact duration, but is computationally very effic...

A nominal controller that is designed without consideration of driver model uncertainty is also tested for comparison. Two types of experiments are proposed. A long driving task with nominal configurations and a short driving task with initially large lateral position error. The data is analyzed using both time domain and frequency domain metrics. In the time ...

The robustness problem is treated both in the case of off-line controller design, where the controller is numerically designed based on values of the disturbance input (as opposed to a model of the disturbance), and in the case of online (adaptive) controller design. Conditions are given in both cases for robust regulation to be ...

A linear second order driver model with parametric and unstructured uncertainty is proposed. We obtain and validate the uncertainty models using the data from real drivers driving a fixed-base driving simulator

The driver behind open architecture is obtaining enhanced system performance at affordable cost. The University of Michigan started a project on open-architecture in 1988. This paper offers a short description of the project, and summarizes the impact of this new technology on the equipment supplier industry (control vendors and machine builders) and the end users of this technology.

Reconfigurable capacity, and optimal capacity management policies, can contribute to increased economic stability. This research introduces a new approach to optimal capacity management for a firm faced with uncertainties and imperfect information of the market demand. It presents an optimal policy for the capacity management problem in a firm facing stochastic market demand, based on Markov decision theory. To make the approach more ...
