Aim of this is to present the alternative HEV (PHEV) concept, potentially more efficient than fuel-cell powertrains, which can in the same time compete with the conventional vehicles (CV) in retail prize, functionality and all drive situations!
Vehicles on road are driven by the power delivered by the engine, which intern is limited by the Road Loads acting over the vehicle under driven state. Most common Loads are Aerodynamic and Rolling resistance.
By using the same concept for braking we can also improve the active safety systems in a vehicle.
The Problem:
Low air pressure tires skid and hydroplane more easily. This greatly consumes more fuel and reduces tire life. A Tire Pressure Monitoring System or TPMS is a system to monitor the air pressure inside the automobiles tires. TPMS alerts to dangerous low-pressure or under inflated tire conditions with both a visual and an audible alert.

INTRODUCTION
Every year more than 1.3 million people die worldwide due to car accidents. As engineering students, it’s our passion to try to find solutions to such problems. For this purpose we wish to develop a system which can help in protecting lives of many people.
The Aerostatic Suspension System is a mechanical contraption that achieves flotation in air of a vehicle and its load by means of a number of cylinder and piston sets (one per wheel). The pistons possess seals that impede the entrance of air as the piston moves within the cylinder.
Problem: In India, getting stuck in traffic is something that everyone has to go through every day. But how often do you see an ambulance with a person struggling for his life stuck behind you. You want to help by giving way, but you can’t cuz you are stuck in traffic and the vehicle before you ain’t moving.
Aid2GPS is a failsafe system for localization of a vehicle, even at times when GPS is unavailable. It employs an optical flow sensing based odometry system and a digital compass to track position and orientation.
WORKING (in a nutshell): Initially a GPS reading is taken to globally localize the vehicle. The backup system then kicks in.
As shown in the figure, the main components of the system are an IC engine, an air compressor, a pneumatic air motor, two heat exchangers and two air storage tanks. For short journeys the vehicle can work only on pneumatic power stored in the tank which can be filled from any power source at home.
Heavy Duty Vehicles have been dealing with high under hood temperatures even before the Environmental Protection Agency mandated their antipollution requirements for October, 2002 engines and the engine manufacturers chose Exhaust Gas Recirculation (EGR) to deal with these requirements.
