The invention relates to a self-driven accelerometer based on a planetary gear structure friction nano-generator, which comprises a planetary gear structure and a zigzag friction nano-generator, and is characterized in that the input end of the planetary gear structure is connected with the axis of an automobile tire; the zigzag friction nanometer generator comprises an upper metal electrode layer, an upper friction layer and a lower metal electrode layer. When a tire rotates, the sliding block of the planetary gear structure is driven to do reciprocating linear motion on the shell support, the sawtooth-shaped friction nanometer generator generates friction charges and induction charges so as to generate voltage and current, the magnitude of the voltage between the upper metal electrode and the lower metal electrode is detected, and by means of the special structure, obtained voltage data are processed, and the detection accuracy is improved. Accurate perception of the driving acceleration of the automobile c
