The invention discloses an automobile atmosphere lamp control method and device and a storage medium. The method comprises the following steps: in an automatic adjustment mode of an atmosphere lamp, acquiring musical attributes of music played at present from a processor of a vehicular audio system and acquiring audio frequency parameters of the music played at present form a power amplifier end of the vehicular audio system; obtaining lamplight parameters of the atmosphere lamp according to the musical attributes, the audio frequency parameters and a preset lamplight control algorithm, and adjusting the atmosphere lamp according to the lamplight parameters. According to the invention, when the vehicular audio system is playing the music, the accuracy of the acquired audio frequency parameters can be improved, and flexible conversion of the atmosphere lamp can be realized through the acquired two kinds of parameters. The synchronization between the conversion of the atmosphere lamp andthe music can be realized, so that a visual effect of the atmosphere lamp in synchronization with the music can be experienced by people in a vehicle.
