A systematic methodology was devised for optimal selection of regenerative braking systems for HGVs in urban environments. This involves power matching between actuator and energy storage, as well as balancing the power and energy performance requirements for particular stopping parameters. Hydraulic systems present the best solution for regenerative braking of HGVs, because hey have their better specific power and specific energy than electrical or kinetic systems do. Hydraulic systems are likely to be 20% lighter and 33% smaller than competing electrical technologies and 16% lighter than a flywheelbased system. In addition to these quantitative measures, a hydraulic system is competitive on cost and packaging for the chosen urban duty cycle. The next step in this research is to create a computer model of a hydraulic regenerative braking system and, using the existing model of the Cambridge Vehicle Dynamics Consortium HGV, to predict the system's possible fuel savings over a simple stop-start cycle. This model will then be run over several standard drive cycles to characterise further the possible fuel savings of this regenerative braking system. Should the benefits prove sufficient, a prototype system will be developed to test the concept.
