The invention discloses a multifunctional holographic multiplexing vehicle window system capable of preventing strong light and a holographic multiplexing method thereof. The system comprises an electric control module, a holographic vehicle window module and a photoelectric conversion module. Wherein the electric control module comprises a projection module, a switch module and a photosensitive element, the projection module generates a target image, the switch module controls the electric switchable element to be switched on and off, and the photosensitive element detects the light intensity level. The holographic car window module comprises car window glass and a holographic functional film attached to the surface of a car window and is used for changing wavefront of light of the outside and the projection module. The photoelectric conversion module receives light collected by the holographic functional film and converts the light into electric energy to supply power to the electric control module. According to the system and the method, while head-up display is realized, interference of external glare on a driver is weakened, temperature rise in a vehicle caused by strong light is inhibited, and the external strong light is collected for supplying power to the electric control module. The driving safety and the practicability of the head-up display system can be effectively improved while the display content is obtained.
