With the development of artificial intelligence and driverless technology, the steer-by-wire system has become the mainstream direction of future development. Its structure is simple, lightweight, and real-time optimized steering gear ratio according to road conditions, steering road feel, and improved vehicle handling stability and active safety. Therefore, the research on the wire-controlled steering control system has great practical value. It is applied to platforms such as electric vehicles and intelligent networked vehicles to realize unmanned driving and optimize intelligent transportation, which has good application prospects. Based on the analysis of the structure of each component of the steer-by-wire system, this paper established the dynamic models of the steering execution part, the rack and pinion part and the steering wheel part, and completed the simulation model of each part and the three closed-loop control of the motor through Simulink. This paper, finally built a Carsim/Simulink co-simulation platform, integrated the motor control strategy into the vehicle model in Carsim, and verified the following characteristics and fast response characteristics of the steer-by-wire model.
