The invention discloses an integrated steer-by-wire system based on a magnetic lead screw and a vehicle. The system comprises the steps that the steering input torque of a driver is collected; the input torque is transmitted and measured, and the rotating angle of the steering wheel module is measured; generating a road feeling simulation torque, increasing the road feeling simulation torque according to a first proportion by adopting a magnetic gear, and loading the road feeling simulation torque to a steering column module; a driving torque of the steering system is generated, a magnetic gear is adopted to increase the driving torque in a second proportion, and meanwhile the driving torque is output to a magnetic lead screw module; a non-contact magnetic force transmission mode is adopted, and rotary motion from the magnetic gear composite driving motor module is converted into linear motion to be output; and the steering wheel is driven to steer under the pushing of the linear motion of the magnetic lead screw module. The mechanical friction characteristic is eliminated, and the control performance of the steer-by-wire system is greatly improved; and meanwhile, the overload protection capability of the steer-by-wire system is expanded.
