The invention provides a steer-by-wire system, a vehicle and a control method of the steer-by-wire system, and relates to the technical field of vehicles. Wherein the steer-by-wire system comprises a first power-assisted steering unit, a second power-assisted steering unit, a first steering execution unit, a second steering execution unit and a hydraulic mechanism, and the hydraulic mechanism comprises an oil storage cavity, an electromagnetic valve and an oil can; the oil storage cavity comprises a first piston rod and a second piston rod which are oppositely arranged, the first piston rod is connected with the first power-assisted steering unit and the first steering execution unit, and the second piston rod is connected with the second power-assisted steering unit and the second steering execution unit. The electromagnetic valve is connected between the oil storage cavity and the oil can and used for opening or closing the oil storage cavity, and when the oil storage cavity is closed, the first piston rod and the second piston rod are arranged in a linkage mode. When the power-assisted unit on one side fails, the power-assisted unit on the non-failed side forms control force for steering on the failed side, so that the driving safety is improved.
