— Using a first-principles approach, the constituent components of a series hybrid electric car are modelled and integrated to form an overall coupled dynamic model. Controllers for the individual components are constructed, and are combined with a load follower supervisory controller and driver model to enable simulation of the vehicle under general(More)
— This paper develops an indirect optimal control methodology to achieve green driving optimisation for series hybrid electric vehicles. Starting from a given vehicle mission, specified in terms of a road journey that has to be completed in a given amount of time, the power sharing among the powertrain sources and the vehicle speed profile along the journey(More)
Burst oscillations can arise in racing motorcycles under a combination of high speeds, low roll angles and firm acceleration. This bursting occurs at weave-mode frequencies under conditions that cause the classical wobble and weave modes interact. Under race conditions this phenomenon can undermine rider confidence, and is consequently detrimental to lap(More)
— A supervisory control system (SCS) that maximizes the overall powertrain efficiency of a series hybrid electric vehicle (HEV) is developed. A novel approach of formulating the overall power efficiency which considers the idling losses of the engine and also characterizes separately the charging and discharging efficiencies of the battery, is proposed.(More)
— This paper proposes a new concept of car active suspension that shows significant advantages with respect to previous systems. The Active Variable Geometry Suspension (AVGS) is based on a passive suspension, in which an extra link/chain of linkages is connected in series to the spring damper unit. One servo-motor per wheel is used to continuously and(More)
