Vehicle atmosphere lamp system with real-time music rhythm control

Abstract

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.

Description

technical field [0001] The invention relates to a vehicle-mounted ambient light system controlled by real-time music rhythm. Background technique [0002] With the popularization of family cars, people have put forward higher and higher demands on the driving experience. Car ambient light is a car interior lighting system that creates and decorates interior lighting scenes. Most of the existing automobiles control the vehicle-mounted ambient lights by controlling the vehicle body, and the control method and control method are single. To increase or decrease the total number of ambient lights requires modification of the vehicle-mounted control protocols of all nodes, and the same system functions are transplanted to another After the first model, the agreement needs to be revised as a whole to adapt to the new model's own upper layer agreement. [0003] In the cars that are popular nowadays, car DVDs will be installed in the car, as a multimedia playback system for audio-vi...
