The invention provides a vehicle atmosphere lamp system with real-time music rhythm control. The vehicle atmosphere lamp system comprises a system host and a plurality of sub-controllers; the system host comprises an ADC signal acquisition module, a CAN signal receiving module, an MCU master controller and an LIN signal output module; the ADC signal acquisition module acquires a music signal in real time, and performs digital quantization coding on the music signal; the CAN signal receiving module defines the quantization coding to a CAN protocol, and samples the quantization coding into an LIN control instruction via a vehicle CAN/LIN system; the MCU master controller receives the LIN control instruction, and processes the LIN control instruction and outputs a control signal; the LIN signal output module sends the control signal to the sub-controllers; and the sub-controllers are atmosphere lamp control modules, and each sub-controller is provided with an LIN signal receiving interface. According to the vehicle atmosphere lamp system with the real-time music rhythm control provided by the invention, a CAN bus is connected with an automobile body system, and an audio signal of a vehicle DVD is directly used for the music rhythm control of the atmosphere lamp, so that the color and the brightness of the atmosphere lamp synchronously change along with the music rhythm in real time, the atmosphere inside the automobile is emphasized, and the visual enjoyment is enhanced.
