The invention aims at providing an automobile headlamp based on light guide and a control method thereof. The reliability, the driving comfort and the driving safety of the headlamp are improved. The automobile headlamp based on the light guide comprises a lens and light-emitting parts and is characterized in that the light-emitting parts are one or more in number, and each light-emitting part can be independently controlled; a light guide part used for guiding light of the corresponding light-emitting part to the lens is arranged between each light-emitting part and the lens. Light rays are guided through the light-emitting parts, and the light-emitting parts can be placed in any positions of the headlamp even the exterior of the headlamp. Thus, the design degree of freedom of the headlamp is larger, and meanwhile heat dissipation of the light-emitting parts is facilitated. According to the automobile headlamp based on the light guide, the light rays are transmitted through the light-emitting parts, the head
