Steer-by-wire system can achieve the goal of personalized driving, assistant driving and unmanned driving through control-by-wire and intelligent control technology. It is the key technology of intelligent networked vehicle landing, and its related dynamic control technology is the core technology that affects the comprehensive performance of steer-by-wire system. This paper introduces the basic structure types and dynamic modeling of the steer-by-wire system, and summarizes the road feel control technology, stability control technology, fault-tolerant control technology and steer-by-wire control technology for intelligent vehicles in full scale. The development process and research status of the steer-by-wire system are analyzed in detail. Finally, the future research trend of steer-by-wire system is prospected. It can be predicted that the control technology of steer-by-wire system will be developed in the direction of accurate execution, full condition coverage, parallel driving, safe and reliable application, and intelligent network connection.
