In order to investigate the effectiveness not only in riding comfort but also in mad handling, an half-car model with the hydro-pneumatic active suspension system is proposed in this study. Whole preview control method and partial preview control method, in which the road information detected by the front wheel is sent to the controller to decide the input to rear suspension, are taken into design of the active suspension control system. Results of numerical simulation show that satisfactory control efficiency could be achieved in both whole preview control and partial preview control. "Ilae comparison of results suggests that whole preview control method can provide better system performance, but the partial preview control method is superior due to its lower cost.

One of the primary factors being lack of public charging infrastructure for such vehicles. This paper presents the potential to increase charge stations by utilizing electricity from electric poles and charge electric vehicles, while charging rate is limited through a charge controller which takes the inputs from electronic data capture machine. Hence every electric pole has a potential of becoming a charge station in its own right. This improvement in charging infrastructure will foster the growth of electric vehicles in Indian market and lead to a better and eco-friendly future.

The job of a suspension system is to contribute to the car's handling and braking for a better safety driving, and to keep the driver as isolated possible from bumps, vibrations, etc. It is important for the suspension to keep the wheel in contact with the road surface as much as possible, since all the forces acting on the vehicle do so through the tires. The suspension also has the important task to protect the vehicle itself and offers comfortable to the driver.

Substances are decomposed, by passing a current through them in the presence of suitable substances, called electrolytes. Electric current causes positively charged hydrogen ions to migrate to the negatively charged cathode, where a reduction takes place in order to form hydrogen atoms. The atoms formed then combine to form gaseous hydrogen molecules (H2). On the other hand, oxygen is formed at the other electrode (the positively charged anode). Hydrogen is a clean burning renewable fuel and does not produce any emissions such as smoke, CO which is major problem in fossil fuel operated engines. Hydrogen is one of the most promising alternative fuels.
