Under the development trend of digitalization, intellectualization and networking, the intelligent driving technology of the automobile is also continuously developed, and manual driving is replaced by automatic driving. Accordingly, automobiles have gradually moved from mechanical mobility tools to new generation mobile smart terminals. After the user is used to intelligent life, the automobile is taken as a movable living space to bear more functions and deal with more scenes. The intelligent cockpit will be the main area of evolution of the car. It is envisioned that future cabins will be the primary vehicle for providing all-round entertainment and interaction.
The karaoke system in the car is quite common in the current car products, and mainly comprises a car entertainment system and a karaoke system which is assembled by parts such as a car sound system and a microphone. In the case of intense market competition, such systems can add mainly some selling points to the car.
In the future, the intelligent driving technology is fully spread and realized, and the intelligent cabins of the whole scene can be fully developed. Therefore, the cabin in the car with the whole scene has the essential entertainment function, and K songs become one of the most important online general entertainment projects in China. For intelligent driving vehicles, a complete set of karaoke systems with light control is even indispensable.
In-car atmosphere lamps in current automobile products are realized by adopting colored lamp strips, and the in-car atmosphere is baked by controlling the lamp strips to display different colors, so that interactivity is lacking. The automobile product also has the advantages that the atmosphere lamp in the automobile is set as the LED lamp strip, so that the control of the LED lamp strip can be realized, the control mode is single, and the automobile has no interactivity with other systems in the automobile, so that the development of the cabin in the automobile with full scene is obviously insufficient.
The invention provides an in-vehicle karaoke control system which is realized by an in-vehicle light control system and an in-vehicle entertainment system. The invention combines controllable light module, karaoke system and vehicle control system, to realize KTV karaoke entertainment light effect and to realize in-vehicle light individuation interaction and projection.
As shown in fig. 1, the in-vehicle light control system includes a central control system, an entertainment system and a light module set in the vehicle. The central control system can be an intelligent driving system and is used for controlling the whole vehicle functions, including a whole vehicle controller and the like. The entertainment system comprises a sound box, a MIC module (a microphone and other radio receiving modules), an APP for executing K songs, a music playing function, a video playing function, various interaction functions in the K song system and the like. The light module dot matrix digital LED lamp can be arranged at any position in a vehicle, including but not limited to an A column, a B column, a C column, a D column, a front beam, a rear beam, a left beam and a right beam in the vehicle, or at least one position, such as a roof and other positions. The multiple groups of the lamp assemblies are arranged in different positions in the vehicle, so that the lamp assemblies are equivalent to neon lamps, seven-color magic lantern slides and color groove lamps in KTV, projection and projection can be realized, and more realistic and better atmosphere experience is provided for users.
Based on the above, when the user starts the karaoke function in the vehicle, the central control system controls the light module and the K song content to synchronously display the light effect by using the in-vehicle light control method.
Referring specifically to fig. 1, fig. 1 shows a schematic block diagram of an in-vehicle lighting control system. As shown in fig. 1, the in-vehicle light control system includes a matrix digital LED lamp disposed in a vehicle; and the central control system is used for controlling the light module.

Illustratively, the central control system converts the music and video information into json files for describing the music and video, and then converts the json files into light description files. The lamplight description file is used for indicating the lamplight module to synchronously emit light or project when the entertainment system plays the video file. The light module can control the luminous effect of any luminous body in the light module based on the light description file.
In one possible implementation, the description file includes LED lamp position information, lamp switch information, LED dot matrix information, PWM information, and LED lamp color information, time information. Fig. 2 is a schematic diagram of light description file information according to an embodiment of the invention, as shown in fig. 2. The LED lamp position information is used for indicating the position of the LED lamp, and is characterized in an A column, a B column, a C column or a D column or a certain beam in the vehicle. The lamp switching information is used for indicating the switching state of a specific LED lamp. The LED array information is used to indicate status information of a certain LED array, such as a projection direction. The PWM information is used for indicating the corresponding pulse width of the single LED lamp, and can be used for controlling the lighting time and the lighting-off time of the LED lamp, so that the flickering effect is realized. The LED lamp color information is used to indicate RGB information of the individual LED lamps, such as controlling brightness, color temperature, hue of the LED lamps.
In some other embodiments, the description file further includes directly callable interaction control information, where the interaction control information is used to respond to a user's interaction when the light control scene is triggered. The control instruction which is analyzed according to the video and audio information of the entertainment system is not needed, for example, related direct light control scenes such as common K singing light control scenes including cheering, applause and the like can be omitted, the light control atmosphere effect can be further increased, and in-car karaoke can be better realized. The lamplight module can directly execute lamplight instructions and light control instructions to realize grouping control of the dot matrix LED lamplight.
With continued reference to fig. 2, in one possible implementation, the entertainment system includes a MIC module and a video playback module that can execute a karaoke APP, such as a car system. The central control system can realize the play control of music, the control of a K song system and the control of a light system, and the synchronization of the light control and the K song system. Therefore, it can be understood that the karaoke system integrates the karaoke into the central control system of the vehicle, and simultaneously utilizes the in-vehicle light control method to realize the atmosphere providing for the control of the light module. Besides, as the central system is used for controlling the whole vehicle, the light module can be independently controlled, the karaoke can be isolated from the light control, and the control of the atmosphere in the vehicle can be independently realized, so that the system is equivalent to a lamp strip atmosphere lamp in the prior art, but more control modes such as projection, more colors and more control modes can be provided than the lamp strip atmosphere lamp.
Further, referring to fig. 3, the central control system includes a man-machine interaction interface and a light scene execution interface. The man-machine interaction interface is connected with the MIC module and used for acquiring voice files, and the light scene execution interface is connected with the video playing module and used for acquiring video files. The MIC module can acquire the voice file of the user in the vehicle, and can also acquire the voice file outside the vehicle, such as rain sound, vehicle flow sound and the like. The in-car central control system is integrated and connected with an in-car sound and MIC module to realize music playing control, K song application and film and television playing, and can analyze music or voice voiceprint files.
In this embodiment, the central control system performs the file parsing. The central control system comprises a light control module, wherein the light control module is used for analyzing the voice file or the video file to generate a light description file related to the voice file or the video file. Illustratively, the light control module converts the voice file or the video file into a json file, and then converts the json file into a light description file.
Further, in one possible implementation manner, the light control module further includes a voiceprint analysis module, where the voiceprint analysis module is configured to perform voiceprint analysis on the voice file, and generate a light description file according to the voiceprint analysis result. In some application scenes, the voice of the user K song is received by the MIC module, and the central control system controls the light module based on the light description file converted by the voiceprint information of the user; in still other application scenarios, when a user plays music in the vehicle, the central control system controls the light module based on the light description file converted by the music file. The light control SDK can be used for realizing the light control SDK, the conversion text light description files such as music files, image files and audio files can be realized by adopting compiling software in the prior art, the control method of the light module is realized according to the corresponding control algorithm, the related technology is mature, and the person skilled in the art can make corresponding application selection according to the requirements.
Still further, in one possible implementation manner, the central control system further includes a light scene editing interface, where the light scene editing interface is configured to obtain a picture drawn by a user and parse the picture into a corresponding light description file. The vehicle-mounted entertainment system comprises a display screen, a user can draw pictures based on the display screen and store the pictures as images, the light control module can convert the images into light description files, and the contents of different positions of different LED projection images can be controlled according to the light mode files. The array type LED can realize projection and projection, is commonly used in intelligent automobiles and can realize functions such as dynamic projection.
In another possible implementation manner, the light scene editing interface is further configured to directly generate a light description file corresponding to the light control scene according to the light control atomic instruction selected by the user and the light control scene defined by the light scene. The user can select and use the integrated lamp control atomic instruction service in some lamp control systems through the scene editor to combine into some personalized light scenes to realize the self-defined light control scene. Different from the scene set in the prior art, the prior art is a fixed function which is well defined in advance in the B end (enterprise end) or the system, and has limited functions and insufficient expansion; the invention can realize the user-defined completion of the user at the C end (user end) based on the self-defined method, and can continuously expand the application scene. For example, a user typically sets a number of usage scenarios for a vehicle, such as camping scenarios, rest scenarios, viewing scenarios, for which custom light effects are typically set, so that when the vehicle is in the corresponding scenario, the light modules may be controlled based on preset or user-set light profiles. For example, when the current vehicle is in a camping scene, the light module can be controlled to project starry sky in the vehicle, so that the atmosphere sense of camping is improved.
In the above embodiment, the light module may be controlled by a controller of the central control system, and the corresponding control function may be integrated on a certain controller module. In other embodiments, the light control may be implemented by a controller that is self-contained with the light module. Therefore, in the invention, the central control system further comprises an SDK interface for calling the description file, the light module further comprises a light controller, and the light controller calls the SDK interface to acquire the description file and analyze the description file.
