Hybrid vehicles in the modern era were developed with a strong primary goal to increase fuel efficiency in the North American market. Over the last 15 years, this market has expanded from zero sales to as high as 3% of total US sales. Most recently, the portfolio of competitive offerings with HEV propulsion systems has grown even more to about 30 models on sale today. Some interesting features and attributes have evolved thru this wider array of products giving the customer much more choice of which characteristics to select to match their needs. Ford�s 3rd generation HEV system will be offered for sale this fall. With it, we have continued our focus on the Fuel Efficiency as the driving force for our efforts. The overall process for the system engineering and some of the relevant subsystem and component contributors to the Fuel Efficiency improvement reflected in the 2013 Model Year Fusion and CMAX Hybrids will be presented. Presenter Charles Gray, Ford Motor Co.

Trans Tech recently debuted the all-electric eTrans school bus providing a total zero emission school bus. The presentation will demonstrate Smith Electric Vehicles and their history with electric vehicles. The presentation will help ensure that everybody has an idea of what the electric school bus will do and to dispel any rumors about the vehicle. Presenter Brian S. Barrington, Trans Tech. Bus
Plugin Hybrid Electric Vehicles (PHEV) have a large battery which can be used for electric only powertrain operation. The control system in a PHEV must decide how to spend the energy stored in the battery. In this paper, we will present a prototype implementation of a PHEV control system which saves energy for electric operation in pre-defined geographic areas, so called Green Zones. The approach determines where the driver will be going and then compares the route to a database of predefined Green Zones. The control system then reserves enough energy to be able to drive the Green Zone sections in electric only mode. Finally, the powertrain operation is modified once the vehicle enters the Green Zone to ensure engine operation is limited. Data will be presented from a prototype implementation in a Ford Escape PHEV Presenter Johannes Kristinsson
