TABLE OF CONTENTS In all types of hybrid vehicles, a supervisory controller must determine how to operate the single power paths to fulfill the power demand of the drive line in the most convenient way. The main objective of that optimization is the reduction of the overall energy use, usually in the presence of various constraints due to driveability requirements and the characteristics of the components.
This chapter describes the theoretical concepts of various types of control strategies for parallel hybrid-electric vehicles. Appendix I contains examples of the application of these ideas. Similar approaches that have been investigated also for series hybrids [228], [16], [33], combined hybrids [178], and fuel-cell hybrids [159], [182] are not treated in this book.
