A novel strategy for the dynamic managment of the load request for the Internal Combustion Engine (ICE) and the Electrical Motor (EM) in a parallel hybrid vehicle is presented. The goal is the performing of a load splitting between ICE and EM subject to the achievement of good drivability of the vehicle in terms of coherence of the torque supply with the driver request (transient performance) for every load splitting between the two motors (static performance). In particular a dynamic allocation scheme is proposed, which dynamically distribute the power demand among the two propulsion systems, using suitable characterizations of their dynamics. Its stability and convergence properties are formally proven and the effectiveness of the control scheme is illustrated via simulations.

Abstract
A novel strategy for the dynamic managment of the load request for the Internal Combustion Engine (ICE) and the Electrical Motor (EM) in a parallel hybrid vehicle is presented. The goal is the performing of a load splitting between ICE and EM subject to the achievement of good drivability of the vehicle in terms of coherence of the torque supply with the driver request (transient performance) for every load splitting between the two motors (static performance). In particular a dynamic allocation scheme is proposed, which dynamically distribute the power demand among the two propulsion systems, using suitable characterizations of their dynamics. Its stability and convergence properties are formally proven and the effectiveness of the control scheme is illustrated via simulations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
