... the benefit of fuel economy. In the charge mode, the electrical system can recuperate energy without fuel consumption as mentioned earlier. However, when the stored energy of the battery is fully charged, the battery is exposed to the overcharge and has no room for the energy recovery. Thus, the discharge...

...Dongsuk Kum; Huei Peng; Norman K. Bucknor Past research on hybrid electric vehicles (HEVs) focused primarily on improving their fuel economy. Emission reduction is another important performance attribute that needs to be addressed. When emissions are considered for hybrid vehicles with a gasoline...

...Mahdi Shahbakhti; Charles Robert Koch Incorporating homogeneous charge compression ignition (HCCI) into combustion engines for better fuel economy and lower emission requires understanding the dynamics influencing the combustion timing in HCCI engines. A control oriented model to dynamically...

...R. Hibino; M. Osawa; K. Kono; K. Yoshizawa A torque converter lock-up clutch slip control system, which is designed to improve fuel economy, must be able to precisely regulate slip speed. Also the system must have a high level of robustness for coping with changes in the operating conditions...

...Feng Zhang; Karolos M. Grigoriadis; Matthew A. Franchek; Imad H. Makki Maximization of the fuel economy of the lean burn spark ignition (SI) engine strongly depends on precise air-fuel ratio control. A great challenge associated with the air-fuel ratio feedback control is the large variable time...

...X. Wei; L. Guzzella; V. I. Utkin; G. Rizzoni Hybrid electric vehicles provide promising alternatives to conventional engine-powered vehicles with better fuel economy and less emission. Realization of these benefits depends, in part, on proper control of the vehicle. This paper examines a variable...

... for the engine inertia, enabling optimal fuel economy in stationary situations without losing driveability during transients. For control design, a simple, nonlinear model is developed and used for feedback linearization. The proposed controller is evaluated by simulations, using an advanced simulation model...
