[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following describes the vehicle-mounted terminal and its control method and device, storage medium, and vehicle according to the embodiments of the present invention with reference to the accompanying drawings.

[0032] The vehicle terminal of the present invention may be a central control device of a vehicle, in which a karaoke application is installed, and the karaoke application may be a karaoke software commonly used by the public, such as "Kuaibo" and "Changba". In order to improve the entertainment experience of users in the vehicle cabin, the present invention proposes a control method for a vehicle terminal, and the specific implementation steps of the control method can be described through the following embodiments.

[0033] Figure 1 It is a flow chart of a control method of a vehicle-mounted terminal in one embodiment of the present invention.

[0034] like Figure 1 As shown, the present invention proposes a control method for a vehicle-mounted terminal, and the control method comprises the following steps:

[0035] S10, after starting the karaoke application, obtaining at least one type of characteristic information of the driver and passengers, including voice characteristic information and action characteristic information.

[0036] Specifically, since the vehicle terminal control method of this embodiment is applied to a karaoke program, in order to save resources, at least one type of characteristic information among the voice characteristic information and action characteristic information of the driver and passengers can be obtained after the karaoke application is turned on. It should be noted that whether the karaoke application is turned on can be specifically confirmed by the currently running program. This embodiment can obtain the currently running program every preset time. If the karaoke application is included, it is determined that the karaoke application is in the turned-on state, otherwise it is determined that the karaoke application is not in the turned-on state. In this embodiment, the preset time can be 0.5 seconds, 1 second, 1.5 seconds, etc.

[0037] In some embodiments, the vehicle includes an image recognizer and a sound recognizer. After the karaoke application is turned on, the image recognizer and the sound recognizer are in working condition. The image recognizer is used to recognize the motion characteristic information of the driver and passengers, and the sound recognizer is used to recognize the sound characteristic information of the driver and passengers.

[0038] Specifically, the image recognizer may be an in-cabin OMS (Occupant Monitoring System) camera, and the sound recognizer may be an in-cabin microphone. Of course, after acquiring the image and sound, the in-cabin OMS camera and the in-cabin microphone may be trained through a network model to identify the corresponding feature information; of course, the corresponding feature information may also be directly identified by comparing with a database, and the present invention may not limit the specific identification method. In some embodiments, the sound feature information includes at least one of pitch, rhythm, voiceprint, spectrum, and volume; the action feature information includes at least one of body movements, facial expressions, and eye movements.

[0039] S20, determining an audio-visual effect control instruction of the vehicle terminal according to the characteristic information.

[0040] Specifically, different feature information can determine different audio-visual effects. For example, when the feature information is booing, a thumbs-down gesture, or a frowning gesture, it can be determined as an audio-visual effect of booing; and when the feature information is applause, applause gesture, thumbs-up gesture, or eyes dilation gesture, it can be determined as an audio-visual effect of cheering. Different audio-visual effects correspond to different control instructions.

[0041] In some embodiments of the present invention, audio-visual effect control instructions of the vehicle-mounted terminal are determined based on feature information, including: inputting at least one of pitch, rhythm, voiceprint, spectrum, volume, body movement, facial expression and eye movement into a trained neural network model to output corresponding audio-visual effects from the neural network model; and determining corresponding control instructions based on the audio-visual effects.

[0042] Specifically, the present embodiment may first train the neural network model according to experimental data or historical data, and the type of the neural network model may not be limited, and may also be a multimodal model, that is, the input parameters may be of various types, such as tone, facial expression, body movement, etc. After the model training is completed, the acquired feature information may be input into the trained model, and then the corresponding audio-visual effects, such as the audio-visual effects of applause and booing, etc., may be output from the model, and then the corresponding control instructions may be determined according to these audio-visual effects, and the vehicle-mounted terminal may achieve the corresponding audio-visual effects after being controlled by these control instructions.

[0043] S30, controlling the vehicle-mounted terminal to produce corresponding audio-visual effects according to the control instruction.

[0044] Specifically, when the audio-visual effect corresponding to the control instruction is cheering, the vehicle-mounted terminal can be controlled to emit sounds related to cheering, such as screaming, whistles, applause, etc., and the corresponding animated picture can also be displayed on the central control screen; when the audio-visual effect corresponding to the control instruction is booing, the vehicle-mounted terminal can be controlled to emit sounds related to booing, such as booing, etc., and the corresponding animated picture can also be displayed on the central control screen.

[0045] In addition, the duration of the audiovisual effect may not be limited in this embodiment, and the duration may also be changed according to the user's settings. Of course, different durations may also be corresponding to different action features and different sound features, for example, the duration corresponding to a gesture may be 5 seconds, the duration corresponding to an eye movement may be 4 seconds, the duration corresponding to an expression movement may be 3 seconds, etc.

[0046] In some embodiments of the present invention, a vehicle includes a karaoke microphone and a plurality of lighting lamps, and the lighting lamps correspond to seat settings of the vehicle. The method further includes: when determining that the karaoke microphone is in use, obtaining seat information of the karaoke microphone or seat information of the karaoke microphone user; and controlling the corresponding lighting lamps to be in an on state according to the seat information.

[0047] Specifically, multiple lights are provided in the cabin, such as search lights, atmosphere lights or reading lights, and what needs to be specified is that different seats are provided with corresponding lights. When a driver or passenger is singing karaoke, the corresponding light can be turned on to create a spotlight effect, making the singer more immersed and further enhancing the karaoke atmosphere.

[0048] In a specific embodiment of the present invention, Figure 2 As shown, after opening the Karaoke APP (Application), the in-cabin OMS camera and the in-cabin microphone can be started, and then the in-cabin OMS camera can recognize user actions, and the in-cabin microphone can recognize user voices. In addition to recognizing the applause of the driver and passengers, the camera can also recognize whether the Karaoke microphone is held. If the Karaoke microphone is held, the user's position can be further determined, and then the search light or reading light of the user's current position can be turned on. When it is recognized that the driver and passengers are applauding, the on-board terminal is controlled to emit a visual / audio effect of applause; and for sound recognition, if the in-cabin microphone recognizes the sound of cheering, the on-board terminal can be controlled to emit a visual / audio effect of cheering.

[0049] In summary, the control method of the vehicle-mounted terminal in the embodiment of the present invention can play audio-visual effects in a timely and accurate manner, thereby improving the user's entertainment immersion experience in the vehicle cabin.
