The invention relates to the technical field of steering columns, and discloses a steering column on-off control device, a steering column and a vehicle. The steering column on-off control device comprises a shifting fork driving unit, a first clutch component and a second clutch component, the first clutch component and the second clutch component are sequentially arranged in the axial direction, the shifting fork driving unit comprises a driving shifting fork capable of moving in the axial direction, one of the first clutch component and the second clutch component serves as a shifting fork matching component, and the other of the first clutch component and the second clutch component serves as a shifting fork matching component. The driving shifting fork and the shifting fork matching part can be rotationally matched and can drive the shifting fork matching part to axially move so as to be switched between a coupling position and a decoupling position; wherein at the coupling position, the first clutch component and the second clutch component are connected to rotate synchronously, and at the decoupling position, the first clutch component and the second clutch component are separated. The on-off control device for the steering column can realize on-off of the steering torque of the steering column.
