An Overview of Drive by Wire Technology for Automobiles

Drive-by-wire is one of the recently developed technologies in automotive industry. Drive by wire technology is also known as "X by Wire" or simply "By Wire" technology. The vehicle equipped with this kind of technology basically runs on electronically controls various range of operations including braking, throttle, Steering and Acceleration. Conventional functioning cars run primarily on hydraulics and mechanical technology to operate the same operations. Conventional system might be powerful but, in the end, are far too complex and not very efficient to wear and tear over the years but Drive by wire technology gives the designer more space due to the replacement of mechanical linkage. Due to the industrialization and innovations in the field of Automotive industry manufacturers and inventors have been used the integrated approach of computers and electronics into modern cars functioning. The functioning of the vehicles is performed by the instructions from computers and sensors. It is also proven to be a boon for the environment by becoming fuel efficient, reduces and improves the engine emissions. This paper describes the concept and types of Drive-by-wire technologies and drawbacks and limitation of it.
