The invention discloses a preparation method of a transverse stabilizer bar capable of actively changing rigidity and the stabilizer bar prepared by the preparation method. The preparation method comprises the following steps of 1, according to the designed size and shape of the transverse stabilizer bar, preparing a transverse stabilizer bar preformed body: preparing and splicing a wrapping layer, a central layer and a shape memory alloy torsion driver assembly of a bar body of the transverse stabilizer bar to form the transverse stabilizer bar preformed body; 2, curing the transverse stabilizer bar and performing forming; and 3, post-curing and post-processing of the transverse stabilizer bar. The transverse stabilizer bar manufactured by the method comprises the bar body and shape memory alloy torsion drivers mounted on the bar body, wherein the bar body comprises the central layer and the wrapping layer; the wrapping layer is a composite material formed by weaving reinforced fibers; each shape memory alloy torsion driver is formed by mixing and weaving shape memory alloy wires and glass fibers; and the manufactured stabilizer bar has an active variable stiffness function, and has the characteristics of light weight, integrally formed structural parts and no corrosion.
