The invention relates to the technical field of advanced manufacture, automated car and railway vehicles, in particular to an advanced manufacturing method of a license plate of an automobile appliedto an advanced drive-assisting system. The method sequentially includes the steps that injection molding is conducted, wherein license plate base materials with various shapes are formed through injection molding; pretreatment of the base materials is conducted, wherein the obtained base materials are subjected to dust removal and electrostatic eliminating; vacuum plating is conducted, wherein two vacuum plating layers, an indium alloy plating layer and an oxide protection plating layer are formed on the surfaces of the base materials through vacuum plating, the total thickness is smaller than 1 micrometer, and the thickness of the indium alloy plating layer is controlled within 10-60 micrometers; deplating is conducted, wherein according to the requirements of different automobile license plates, coating-resisting paint is coated on the vacuum plating layers; a colored paint layer is formed, a protection paint layer is formed, bonding with a base is conducted, and inspection and packaging are conducted. According to the manufacturing method of the license plate of the automobile, it can be ensured that the license plate has a good metal feeling, enough strength, high stability, long service life and good production qualification rate, and meanwhile the performance of a radar can be gave full play to as normal.
