The embodiment of the invention provides a projection system, a vehicle-mounted head-up display device and a vehicle. Wherein the projection system comprises an illumination module, a display chip and a projection lens which are arranged in sequence; the projection system further comprises a focusing module. One part of projection light emitted by the projection lens is projected to a first position through the focusing module to form a first imaging surface, the other part of the projection light is projected to a second position to form a second imaging surface, the first imaging surface and the second imaging surface are arranged in a vertically staggered manner, the first imaging surface is close to the projection lens, and the second imaging surface is close to the projection lens. The second imaging surface is far away from the projection lens, and the focusing module is located between the projection lens and a light path of the first imaging surface. According to the projection system provided by the embodiment of the invention, clear images can be formed on the two imaging surfaces at the same time, so that double virtual image imaging of the vehicle-mounted head-up display device can be realized.
