The paper focuses on the simulation, analysis and control of the energy flows in a parallel hybrid electric vehicle (HEV). HEVs operation is concerned with the on board conversion of chemical, electrical and mechanical energy and its optimal control is essential in order to increase the global system efficiency. A dynamic model is used to describe the driver-vehicle interaction for a generic tr...

Left ventricular assist devices (LVADs) are increasingly used for the treatment of end-stage congestive heart failure, both as a bridge to transplantation and as destination therapy (1). The HeartWare HVAD (HeartWare Inc, Framingham, MA, USA) is a continuous centrifugal-flow left ventricular assist device with a magnetic levitating rotor pump. The pump weighs just 140 g and its small design all...

A fuel-optimal control algorithm is developed for a heavy diesel truck that utilizes information about the road topography ahead of the vehicle when the route is known. A prediction model is formulated where special attention is given to properly include gear shiŸing. e aim is an algorithm with su›ciently low computational complexity. To this end, a dynamic programming algorithm is tailored, an...

Electric vehicle sales are growing globally in response to the move towards a greener environment and reduction greenhouse gas emissions. As any machine, grease lubricants will play significant role component life of these new power plants drivetrains. In this paper, lubrication electric vehicles (EVs) hybrid (HVs) be discussed terms performance requirements. Comparisons EVs HVs for requirement...

This study deals with the design of a near-field wireless power transfer (WPT) system applied to left ventricular assist device (LVAD) treat patients heart-failure problems. An LVAD is an implanted electrically driven pump connected heart and traditionally powered by batteries external human body via percutaneous driveline cable. The main challenge wirelessly powering deep in relatively high ef...

The simulation-based investigation of the variable displacement engine is motivated by a desire to enable unthrottled operation at part load, and hence eliminate pumping losses. The mechanism modeled in this work is derived from a Hefley engine concept. Other salient features of the proposed engine are turbocharging and cylinder deactivation. The cylinder deactivation combined with variable dis...
