In the prior art, a common adjustment mode of an atmosphere lamp in a vehicle is to adjust the atmosphere lamp based on the emotion of a driver or based on the rhythm of music; the two adjustment modes generally have the following problems:
1. adjusting based on the emotion of the driver, namely adjusting the color and the brightness of the atmosphere lamp by collecting emotion data of the driver; for example: in the patent with the bulletin number of CN115402333A and the patent name of in-vehicle interaction control system and method based on the emotion of the driver and storage medium, the emotion of the driver is adjusted in an adaptive atmosphere lamp adjusting mode and a corresponding music playing mode according to emotion data of the driver, so that a relaxed and pleasant driving atmosphere is created, and the fatigue of the driver is relieved. Although the emotion of the driver can be effectively regulated by the regulating method, the emotion of the driver is often aggravated according to the mode that the driver plays corresponding music according to the emotion; for example, the current mood of the driver is more excited, and the control system in the vehicle not only adjusts the atmosphere lamp to be red and bright, but also plays more exciting music at the same time, and the adjusting mode easily causes the driver to be over excited, so that the driving safety is not easy to ensure.
2. Adjusting based on the rhythm of music, namely directly converting the music into a digital signal according to an audio analog signal and controlling the atmosphere lamp; for example: patent publication number CN114828359A, patent name is music-based atmosphere lamp display method, device, equipment and storage medium, and discloses a method for adjusting atmosphere lamps based on music rhythm. Although the atmosphere lamp follows the sound output to perform the rhythm, the effect is not necessarily wanted by the customer; examples: the driver's current mood is poor, and as a result the rhythm following the sound output is red and bright, which may lead to a worse driver's mood.
