INTRODUCTION
Cars are immensely complicated machines, but they do an incredibly simple job.
Most of the complex stuff in a car is decided to turning wheel
The two basic elements that largely dictate car design today are 1. The internal combustion engine 2. Mechanical and hydraulic linkages
HY-WIRE BASICS
The defining characteristic of the Hy-wire is that it doesn’t have either of those two things: engine and mechanical and hydraulic linkages
Instead of an engine, it has a fuel cell stack
Instead of mechanical and hydraulic linkages, it has a drive by wire system
FUEL CELL –ON HY-WIRE
A fuel cell is an electrochemical energy conversion device that converts hydrogen and oxygen into water, producing electricity and heat in the process.
It provides a DC (direct current) voltage
It can continually recharge a fuel cell by adding chemical fuel- hydrogen for an onboard storage tank
DRIVE BY WIRE TECHNOLOGY
The ‘brain’ of Hy-Wire is a central computer housed in the middle of the chassis.
It sends electronic signals to
The motor control unit to vary the speed.
The steering mechanism to maneuver the car.
The braking system to slow the car down .
It is connected to an array of advanced sensors.
The computer is connected to the body’s electronics through universal docking ports
X-Drive
X-drive is the driver’s control unit .
It has two ergonomic groups , positioned to the left and right of a small LCD monitor.
The color monitor in the center of the controller displays speed, mileage, fuel level and the rear-view images from video cameras on the sides and back of the car, in place of conventional mirrors.
A second monitor, on a console beside the driver, shows you stereo, climate control and navigation information.
FUTURE OF HY-WIRE
Fuel cells offer a promising alternative
They need to be compelling, affordable, and profitable.
The main challenge is in the field of storage of hydrogen
CONCLUSION
The Hy-wire concept has so profoundly brought about changes in the automotive industry
GM and other auto makers are planning
to launch such a vehicle for the public usage by the year 2020.
