The invention relates to an optical signal projection unit, a vehicle and a projection method. Wherein the optical signal projection unit comprises a projection part, and the projection part comprises a free-form surface lens piece, a film piece and a projection lens which are sequentially arranged from upstream to downstream; wherein the film piece comprises a light-transmitting area and a non-light-transmitting area, and the shape of the light-transmitting area provides a projection signal pattern of the light signal projection unit; the curved surface structure of the free-form surface lens piece corresponds to the shape of the light-transmitting area of the film piece piece. A light path provided by the light signal projection unit comprises the steps that a light beam is emitted from a light source part, most of the light beam is projected to a light-transmitting area of the film piece after the light beam passes through the free-form surface lens piece, most of the light beam passes through the light-transmitting area and then is emitted through the projection lens, and the light beam passes through the free-form surface lens piece. And providing a projection signal pattern corresponding to the light signal projection unit.
