The Hy-wire (Hydrogen drive-by-wire) is a conceptcar from General Motors originally introduced in

January 2002.

The car runs on hydrogen fuel cells. Uses a drive-by-wire system, meaning that the car

is controlled electronically.

No need of conventional engine.

All equipments needed are in a very compact place.


3/24

Two basic elementslargely dictate car

design today:

internal

combustion

engine

hydraulic

linkages


4/24

An internal combustion engine requires alot of additional equipment to functioncorrectly.

No matter what else they do with a car,designers always have to make room.

The same goes for mechanical andhydraulic linkages.

But the basic function of a car remains thesame however they are built.

1. Instead of an engine, it has a fuel cell stack,

which powers an electric motor connected to

the wheels.

2. Instead of mechanical and hydraulic linkages,it has a drive by wire system based on inputfrom an electronic controller.

3. This is the same control system employed inmodern fighter jets as well as manycommercial planes.


7/24

A computer actually operates the componentsthat move the wheels, activate the brakes andso on, based on input from an electroniccontroller.

Electromechanical actuators and human-machine interfaces such as pedal andsteering feel emulators are used.

Very user friendly and comforting system


8/24

There is no steering wheel, there are nopedals and there is no engine compartment.


9/24

Every piece of equipment that actuallymoves the car along the road is housed inan 11-inch-thick (28 cm) aluminiumchassis at the base of the car.

Enough space inside. Better drive view.

11/24

Its the usermachine interface. Can slide to eitherside of the vehicle Has twoergonomic grips,positioned to theleft and right ofsmall LCD monitor.


12/24

Glide the grips up and down lightly

For steering

Turn either grip, in the same way

you would turn the throttle on a

motorcycleTo accelerate

Squeeze either grip.

For braking


13/24

1. They also generate electricity by chemicalreactions like batteries.

2. Can be continuously recharged3. Very efficient.


14/24

Anode side:

2H2 => 4H+

+ 4e-

Cathode side:

O2 + 4H+ +

4e- => 2H2O

Net reaction:

2H2 + O2 =>

2H2O

16/24

Made up of 200 individual cells connected inseries.

Collectively provide 94 kilowatts ofcontinuous power and 129 kilowatts at peakpower.

The motor controller boosts this up to 250 to380 volts and converts it to AC current to

drive the three-phase electric motor thatrotates the wheels

23/24

General Motors says it fully intends to releasea production version of the car in 2015,assuming it can resolve the major fuel andsafety issues.

It is certainly a good illustration of variousways cars might evolve in the near future.
