Abstract
Reducing the environmental impact of ground vehicles is one of the most important
issues in modern society. Construction and agricultural vehicles contribute to pollution
due to their huge power trains, which consume a large amount of petrol and produce
many exhaust emissions. In this study, several recently proposed hybrid electric archi-
tectures of heavy-duty working vehicles are presented and described. Producers have
recently shown considerable attention to similar research, which, however, are still at
the initial stages of development. In addition, despite having some similarities with the
automotive field, the working machine sector has technical features that require specific
studies and the development of specific solutions. In this work, the advantages and dis-
advantages of hybrid electric solutions are pointed out, focusing on the greater electro-
mechanical complexity of the machines and their components. A specific hybridization
factor for working vehicles is introduced, taking into account both the driving and the
loading requirements in order to classify and compare the different hybrid solutions.
Keywords: hybrid, electric driveline, working vehicle, hybridization factor
1. Introduction
Over the past decades, the efficiency of vehicles has become a highly discussed topic due to
pollution regulation requirements. Modern internal combustion engines (ICEs) have already
reached remarkable performances compared with the engines of the early 1990s. However,
they are still unable to consistently reverse the growth trend in pollutant emissions because
the number of vehicles is also constantly increasing [1, 2]. The European Union first intro-
duced mandatory CO2 standards for new passenger cars in 2009 [3] and set a 2020-onward
target average emission of 95 g CO2/km for new car fleets. The automotive industry devotes
