The invention discloses a rotation limiting device, a steering system and a rotation limiting method.The rotation limiting device comprises a steering component, a transmission component, a stop component and a mounting base, the steering component and the transmission component are rotatably mounted on the mounting base, the transmission component comprises a transmission block and a three-blade shifting piece, and the stop component limits the rotation range of the transmission block; the three-blade plectrum is provided with three plectrum branches, the steering component is provided with a steering plectrum, when the steering plectrum rotates to make contact with the middle plectrum branch, the steering component drives the transmission component to rotate, when the steering plectrum is separated from the middle plectrum branch, the transmission block abuts against the stop component, and when the steering plectrum rotates in the same direction to make contact with the end plectrum branches, the transmission block abuts against the stop component. The transmission part limits rotation of the steering part, and when the steering shifting piece reversely rotates to make contact with the end shifting piece branch, the transmission part rotates back. The steer-by-wire hard stop point can restrain the rotation stroke of a steering component, fills the blank in the field of steer-by-wire hard stop points when applied to a steering system, and meanwhile reduces rotation friction force.
