Hardware and software involved in this embodiment:

1. a vehicle host; for short: main unit

2. A domain controller; for short: domain control

3. The multi-color LED is provided with an atmosphere lamp holder of the single chip microcomputer; for short: single chip lamp holder

4. An ambience light controller (LIN-RGB converter, MCU); for short: controller

5. A multi-color LED atmosphere lamp holder; for short: common lamp holder

6. The transmission signals comprise CAN signals communicated with the domain controller by the host and LIN signals communicated with the atmosphere lamp holder controller by the domain controller;

the atmosphere lamp adopts an integrated design scheme with an atmosphere lamp controller, the atmosphere lamp controller is a single chip microcomputer, and the single chip microcomputer is provided with three pins which are respectively a power line, an LIN line and a ground line; the output pin of the singlechip is provided with 7 pins, namely a power line, a LIN line, a ground line, an R, G, B line and a 5V power output line. The atmosphere lamp holder controlled by the single chip microcomputer is provided with four pins, namely R, G, B wires and a ground wire. The single chip microcomputer controls the lighting and power supply control of the lamp cap through the pins.

The control principle of the application is as follows:

1. the host computer communicates with the domain controller through a CAN signal;

2. and after receiving the welcome running water lamp starting signal and the vehicle unlocking signal at the same time, the domain controller transmits the signals to the lamp holder of the single chip microcomputer through the LIN signal. LIN signals are sent to different single chip microcomputer lamp caps at the same time interval, and after the single chip microcomputer lamp caps analyze the signals, the atmosphere lamps are sequentially turned on from the left rear door → the left front door → the instrument panel left atmosphere lamp → the auxiliary instrument panel right atmosphere lamp → the right front door guard plate → the right rear door guard plate.
