STEER- BY WIRE

STEER- BY WIRE

ABSTRACT

It’s a saying:
“Technology drives the world”

In this technology driven world automobile industry is the fastest growing industry.

As we know, automobile industry is a growing industry and many changes are being made in automobiles for the safety and comfort of passengers.

Steer-by wire technology is named so because it uses electronic components and wires and it removes heavy mechanical parts from a vehicle. Steer-by wire technology is still under research.

This system enables to provide better safety and comfort to passengers according to today’s environment conditions. Additionally, some other benefits are expected, e.g. design freedom, reduced packaging problems, increased ecology and economy.

A question may arise in one’s mind “If there is any electronic failure, is the system reliable for driving?” In Fly-by wire (aero planes), hydraulic backup is provided in case of any electronic circuit failure. But, in case of Steer-by wire (automobiles) different processors are used to control different mechanisms. In case of any failure the main processor will provide backup. This main processor is called “Mother Processor.”

For car designers and stylists, drive-by-wire systems have the potential to transform the way passenger compartments are designed. Gone will be the costly hydraulically assisted mechanical packages that actuate and assist both brakes and steering. Along with them go the bundles of wires that sit behind the instrument panel, because this generation of cars will be using electronic and optical data buses. These distribute control signals from the variety of control units that look after engine management, instruments, safety systems, windows, comfort features, heating and ventilation, lighting and so on.

Removing the mechanical linkage between the steering wheel and the steering rack will not only enhance design and crashworthiness (because there is no steering column to push through into the driver’s chest), it will massively simplify and lower the cost of switching between right-hand and left-hand drive.
