Book Description
This book assembles new methods showing the automotive engineer for the first time how hybrid vehicle configurations can be modeled as systems with discrete and continuous controls. These hybrid systems describe naturally and compactly the networks of embedded systems which use elements such as integrators, hysteresis, state-machines and logical rules to describe the evolution of continuous and discrete dynamics and arise inevitably when modeling hybrid electric vehicles. They can throw light on systems which may otherwise be too complex or recondite. Hybrid Systems, Optimal Control and Hybrid Vehicles shows the reader how to formulate and solve control problems which satisfy multiple objectives which may be arbitrary and complex with contradictory influences on fuel consumption, emissions and drivability. The text introduces industrial engineers, postgraduates and researchers to the theory of hybrid optimal control problems. A series of novel algorithmic developments provides tools for solving engineering problems of growing complexity in the field of hybrid vehicles. Important topics of real relevance rarely found in text books and research publications—switching costs, sensitivity of discrete decisions and there impact on fuel savings, etc.—are discussed and supported with practical applications. These demonstrate the contribution of optimal hybrid control in predictive energy management, advanced powertrain calibration, and the optimization of vehicle configuration with respect to fuel economy, lowest emissions and smoothest drivability. Numerical issues such as computing resources, simplifications and stability are treated to enable readers to assess such complex systems. To help industrial engineers and managers with project decision-making, solutions for many important problems in hybrid vehicle control are provided in terms of requirements, benefits and risks.

Book Description
Optimal Control of Hybrid Vehicles provides a description of power train control for hybrid vehicles. The background, environmental motivation and control challenges associated with hybrid vehicles are introduced. The text includes mathematical models for all relevant components in the hybrid power train. The power split problem in hybrid power trains is formally described and several numerical solutions detailed, including dynamic programming and a novel solution for state-constrained optimal control problems based on the maximum principle. Real-time-implementable strategies that can approximate the optimal solution closely are dealt with in depth. Several approaches are discussed and compared, including a state-of-the-art strategy which is adaptive for vehicle conditions like velocity and mass. Three case studies are included in the book: • a control strategy for a micro-hybrid power train; • experimental results obtained with a real-time strategy implemented in a hybrid electric truck; and • an analysis of the optimal component sizes for a hybrid power train. Optimal Control of Hybrid Vehicles will appeal to academic researchers and graduate students interested in hybrid vehicle control or in the applications of optimal control. Practitioners working in the design of control systems for the automotive industry will also find the ideas propounded in this book of interest.

Book Description
This SpringerBrief deals with the control and optimization problem in hybrid electric vehicles. Given that there are two (or more) energy sources (i.e., battery and fuel) in hybrid vehicles, it shows the reader how to implement an energy-management strategy that decides how much of the vehicle’s power is provided by each source instant by instant. Hybrid Electric Vehicles: •introduces methods for modeling energy flow in hybrid electric vehicles; •presents a standard mathematical formulation of the optimal control problem; •discusses different optimization and control strategies for energy management, integrating the most recent research results; and •carries out an overall comparison of the different control strategies presented. Chapter by chapter, a case study is thoroughly developed, providing illustrative numerical examples that show the basic principles applied to real-world situations. The brief is intended as a straightforward tool for learning quickly about state-of-the-art energy-management strategies. It is particularly well-suited to the needs of graduate students and engineers already familiar with the basics of hybrid vehicles but who wish to learn more about their control strategies.

Book Description
The primary objective of this dissertation is to develop a hybrid powertrain control strategy that minimizes fuel consumption based on prior knowledge of the driven route. The primary contributions of this research work are: development of a driver classification strategy, development of a route learning and detection system to predict the driven route, and development of a global optimization based powertrain control strategy to minimize the fuel consumption for the predicted route. A driver classifier has been modeled using real time monitoring of some key dynamical parameters of a vehicle, such as, vehicle acceleration, braking, speeding index and throttle activity index. This classifier uses vehicle's powertrain signals to extract the above parameters and classifies a driver into one of three categories, aggressive, moderate and conservative using a Bayesian classifier. In the route learning technique, the learned information comprises of feedback from the vehicle's acceleration and brake sensors, steering wheel angle, driver torque demand, and data from the vehicle's lateral and longitudinal acceleration sensors. The processed route attributes, such as turns, road curvature, road grades, posted speeds and traffic lights are stored in a database in the powertrain microcontroller memory. When the vehicle is driven, the driven route is compared with the attributes stored in the memory for previous routes and identified either as a new route or one of the stored routes. When the vehicle is driven on one of the learned routes, a Hidden Markov Model based algorithm is used to predict the driven route and establish a confidence estimate for the predicted route. The hybrid powertrain is optimized using future route information. The control strategy uses real-time Fibonacci optimization to minimize gasoline fuel consumption using control actions, such as, engine on/off, transmission gear shifting, blended hybrid operation, regenerative braking and battery state of charge management strategy based on the available look-ahead information. The results indicate that substantial fuel savings can be achieved if the powertrain operation can be customized based on the driving style of the driver and advanced knowledge of the driven route.
