Steer-By-Wire is an advanced steering technology. As the mechanical connections between steering wheel and turning wheels are eliminated, the drive ratio can be designed according to needs, the turning wheels can be controlled actively compensating the parameters with vehicle speed variation, thus ideal steering characteristics is realized and handling stability is improved. Research development of home and abroad of Steer-by-Wire technology is summarized, structure, key technologies and study methods of Steer-by-Wire is introduced and developing trend of Steer-by-Wire is presented.
