The principal objective of the project is to research and develop a mild hybrid powertrain system designed specifically to meet the duty cycle of an urban delivery HGV in the range 7.5T to 15T. The project is split into four main areas of activity: * Component development; * Component integration; * Powertrain analysis; and * Vehicle monitoring.

This project will research the application of a mild hybrid powertrain to an HGV delivery vehicle in the 7.5T to 15T range. Typically the duty cycle of this class of vehicle is dominated by multiple short journeys in urban area, with short to medium length journeys occurring infrequently. Consequently, overall powertrain efficiency is low, principally as a result of the high proportion of stop/go driving in the urban environment. This efficiency level can be improved greatly via the applicationof a mild hybrid powertrain system that permits all-electric propulsion at low speeds without compromising the high efficiency of the existing diesel engine during highway driving. A mild hybrid powertrain offers several advantages. It will enable the vehicle to have zero emissions in sensitive urban delivery areas while the pollution associated with extra-urban transit of goods will be reduced. Operating costs should also be reduced due to improved fuel economy and extended component life.
