[0053] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0055] Figure 1This is a flow chart of a seat audio channel switching method provided by an embodiment of the present disclosure. This method is applicable to smart cars and can solve the technical problem of inconvenient channel switching. This method can be executed by a seat audio channel switching device, which can be implemented in software and / or hardware. For example, this method is executed by a car controller. Figure 1 As shown, the method includes the following steps:

[0056] S110: Obtain the passenger's position information and obtain the passenger's sight line information.

[0057] In some embodiments, the controller can obtain the occupant's position information and the occupant's line of sight information through the Occupant Monitoring System (OMS). OMS usually uses a camera, which is generally placed below the rearview mirror. It can identify the occupant's behavior and understand the occupant's condition through algorithms. The main functions include personnel line of sight monitoring, face recognition, motion recognition, expression recognition, etc. OMS can further improve the safety performance of the car by monitoring the perception data of the occupants in the cabin. The seat belt warning function is one of the basic functions of OMS. In addition, OMS can also help determine whether the passengers in the car are safely seated, whether there are children or pets left alone, fatigue driving monitoring, dangerous driving behavior monitoring, etc.

[0058] When an audio source device in the vehicle outputs audio, the OMS monitors the occupants' seating position and line of sight to determine whether they are looking at a specific audio source device. Audio source devices can be categorized as in-vehicle devices and mobile devices. In-vehicle devices refer to audio source devices that come with the vehicle, such as the central control screen or ceiling-mounted display. Mobile devices refer to audio source devices brought into the vehicle by passengers, such as mobile phones, laptops, and tablets.

[0059] S120: Determine whether the time that any passenger's sight stays on any audio source device reaches a preset time. If so, obtain the target seat audio corresponding to the passenger's position information.

[0060] Based on line of sight information, if the controller detects that a passenger's line of sight falls within the calibrated range of any audio source device for a preset time (e.g., 3 seconds), it determines that the passenger is viewing the audio source device. The controller then combines this with the monitored seating information to determine the passenger's seat and identifies the seat speaker in that seat as the target seat speaker.

[0061] S130: Switch the audio channel of the target seat audio system to the audio source device.

[0062] Audio source devices are divided into two categories: vehicle-mounted devices and mobile devices. In the embodiments of the present disclosure, the channel switching process is different for different audio source devices.

[0063] For vehicle-mounted devices such as the central control screen and ceiling screen, these vehicle-mounted devices and the seat speakers are usually connected through the audio lines inside the vehicle. When the channels are switched, the audio signal of the vehicle-mounted device can be synchronized to the target seat speaker, and the audio is played externally by the headrest speakers on the seat.

[0064] For mobile devices such as mobile phones, laptops, tablets, etc., which are generally connected to the seat audio system via Bluetooth, the system can combine the passenger's seat information to issue a channel switching prompt, actively prompting the passenger whether the mobile device needs to match the current seat audio system's Bluetooth connection, and then determine whether to switch the seat audio system's channel based on the passenger's response instructions.

[0065] The channel switching prompt information in the disclosed embodiment is a voice announcement, delivered via Text-to-Speech (TTS) technology. TTS technology first analyzes and converts text into a sequence of phonemes, the basic unit of speech and the smallest meaningful sound segment. The phoneme sequence is then converted into acoustic features, such as pitch, volume, and intonation. These acoustic features are then converted into digital signals and transformed into sound through the seat speakers.

[0066] Existing methods for switching audio channels include manual switching, voice switching, or setting up an audio conflict mechanism to switch audio channels based on priority. There's no precedent for switching audio channels based on line of sight. The disclosed embodiments are the first to use visual perception to switch the corresponding audio source device and its channel. By combining the passenger's line of sight with their seat position information, the disclosed embodiments instantly switch the audio channel of the seat audio system in the passenger's seat to the audio source device they're looking at. This eliminates the need for manual channel switching by the passenger, significantly improving the convenience of channel switching and resolving the technical issue of inconvenient channel switching.

[0067] Figure 2 This is another flow chart of a channel switching method for a seat audio system provided by an embodiment of the present disclosure. Figure 2 and one Some application examples are used to illustrate the channel switching method of the seat audio system. This method can be executed by a channel switching device for the seat audio system, which can be integrated into the controller of the car. It mainly includes a detection module, a judgment module and an execution module, and can be implemented in software and / or hardware. Among them, the detection module obtains the seat information and line of sight information of the occupants in the car through the OMS camera, so as to judge whether the occupants are looking at the sound source device, and the judgment module and the execution module switch the channels based on the results output by the detection module. The line of sight monitoring and seat monitoring algorithms relied on by the channel switching device of the seat audio system are relatively mature, and hardware equipment such as in-car cameras, multiple screens and headrest seat audio systems are also gradually becoming popular, and no additional hardware costs are involved.

[0068] First, the vehicle is started and the vehicle systems are powered on. The detection module confirms that the OMS is enabled and functioning properly. The OMS then monitors the occupant's position within the vehicle, obtaining information about the occupants' seating arrangement. If the seating arrangement changes, such as when a passenger changes seats or enters or exits the vehicle, the seating arrangement is updated accordingly. Simultaneously, occupant gaze information is monitored in real time to determine whether each occupant is looking at a specific in-vehicle device or a mobile device.

[0069] When the OMS detects that a passenger's gaze falls within the calibrated range of the audio source device for a preset time, for example, 3 seconds, it prepares to switch the channel of the corresponding seat audio. The judgment module determines the switching method based on the different types of audio source devices.

[0070] If the audio source device is an in-vehicle device, direct channel switching is possible because in-vehicle devices like the central control screen and ceiling-mounted display are typically connected to the seat audio system via the vehicle's internal audio lines. The determination module outputs the occupant's seat information and the device information of the audio source device the occupant is looking at to the execution module.

[0071] The execution module obtains device information of the vehicle-mounted device, and then switches the sound channel of the target seat audio to the vehicle-mounted device based on the device information.

[0072] In one application example, three generations of a family are traveling in a car. The mother is in the first-row passenger seat, watching the central control screen, while the passenger seat speakers play the central control screen's audio. The grandmother is in the second row, playing on her phone while watching cartoons on the ceiling-mounted screen with her child. While the grandmother is watching the first-row central control screen, the seat speakers in her seat switch to the central control screen's audio channel and play the central control screen's audio. When she looks up at the second-row ceiling screen, the seat speakers in her seat switch to the ceiling screen's audio channel and play the ceiling screen's audio.

[0073] When the OMS detects that a certain passenger is looking at a mobile device, such as when the grandmother looks down at her mobile phone, the judgment module first obtains the Bluetooth ID of the sound source device. If there are multiple mobile devices in the car, the system obtains the Bluetooth ID of the mobile device closest to the target seat audio from the Bluetooth IDs of multiple mobile devices. For example, if there are multiple mobile phones in the car, each mobile phone has a Bluetooth ID. Based on the principle of closest distance, the system can use the mobile phone closest to the seat audio (target seat audio) of the grandmother's seat as the sound source device to establish a Bluetooth connection, and obtain the Bluetooth ID of the mobile phone. Based on usage habits, passengers in most cases look at the mobile device in their hands, and the mobile device is also closest to the target seat audio of the passenger's seat. Therefore, according to the principle of closest distance, the Bluetooth ID of the correct mobile device can be obtained with the greatest probability.

[0074] Based on the Bluetooth ID, the system then checks whether a Bluetooth connection has been established between the target seat audio system and the mobile device during the current ignition cycle. For electric vehicles, the ignition cycle is the time from vehicle power-up to vehicle power-down; for gasoline vehicles, the ignition cycle is the time from engine startup to engine shutdown.

[0075] If a Bluetooth connection has been established between the target seat audio system and the mobile device, it means that this is not the first time that the target seat audio system has established a Bluetooth connection with the mobile device during this ignition cycle. Based on the Bluetooth ID, the execution module establishes a Bluetooth connection between the target seat audio system and the mobile device, and switches the audio channel of the target seat audio system to the mobile device, avoiding sending a channel switching prompt message to the occupants every time the switch is made, causing excessive disturbance to the occupants.

[0076] If the target seat audio system has not previously established a Bluetooth connection with the mobile device, this indicates the first time the target seat audio system has established a Bluetooth connection with the mobile device during this ignition cycle. A channel switch prompt can be issued, prompting the occupant to switch channels. For example, using text-to-speech (TTS) technology, the seat audio system can issue a voice message stating, "Switch to mobile audio?" If the occupant responds with "yes" or "switch," the execution module establishes a Bluetooth connection between the target seat audio system and the mobile device based on the Bluetooth ID, switching the target seat audio system's channel to the mobile device.

[0077] The voice broadcast information can also be "will switch to mobile phone audio in 3 seconds". Whether the occupant answers "yes" or does not answer, it can be regarded as an instruction to agree to the switch. The execution module will establish a Bluetooth connection between the target seat audio and the mobile device based on the Bluetooth ID, and switch the audio channel of the target seat audio to the mobile device.

[0078] When the occupant answers to reject the switching instruction, such as "No" or "Do not switch", it means that the occupant does not agree to switch the channel. Then, during this ignition cycle, the Bluetooth of the mobile device will no longer be connected, and the channel switching prompt information will no longer be issued to the mobile device.

[0079] In some embodiments, the channel switching prompt can also be a text prompt, such as a text prompt displayed on a mobile phone screen asking "Switch to mobile audio?" The occupant clicks "OK," indicating their agreement to switch channels. The execution module then establishes a Bluetooth connection between the target seat audio system and the mobile device based on the Bluetooth ID, and switches the channel of the target seat audio system to the mobile device.

[0080] The text prompt message can also be "Will switch to mobile phone audio in 3 seconds". The occupant's click of "OK" or no operation can be regarded as an agreement to the switching instruction. The execution module will establish a Bluetooth connection between the target seat audio and the mobile device based on the Bluetooth ID, and switch the audio channel of the target seat audio to the mobile device.

[0081] When the occupant responds to reject the switching instruction, for example, clicking "Cancel", it means that the occupant does not agree to switch the channel. Then, during this ignition cycle, the Bluetooth of the mobile device will no longer be connected, and the channel switching prompt information will no longer be issued to the mobile device.

[0082] In some embodiments, the channel switching prompt information can also be sent out as a voice broadcast information and a text prompt information at the same time, and the occupant can answer verbally or manually click to answer.

[0083] To prevent channel switching notifications from disturbing passengers, once a Bluetooth connection has been established between the seat audio system and a mobile device, the passenger is automatically deemed to have agreed to the channel change. The second or subsequent time the seat audio system needs to switch to the same mobile device's channel, the channel change notification will not be displayed. Instead, the Bluetooth connection between the target seat audio system and the mobile device will be established, and the target seat audio system's channel will be switched to the mobile device.

[0084] In some embodiments, the seat audio system also supports channel switching between multiple mobile devices. For example, if a passenger has multiple mobile phones and is using them all, the seat audio system will keep a separate Bluetooth connection record with each phone and automatically switch audio channels between them.

[0085] In some embodiments, the seat audio channel switching method may further include: determining whether the position information of any passenger has changed.

[0086] If so, the original seat audio corresponding to the original position information before the occupant's position information changes and the original sound source device connected to the sound channel of the original seat audio are obtained, and the sound channel connection between the original seat audio and the original sound source device is cut off.

[0087] If any passenger's seat information changes, that is, if a passenger changes seats or gets off the bus, the original seat audio system for that passenger is retrieved, along with the audio source device currently connected to that seat audio system's audio channel (i.e., the original audio source device). Since the passenger has left their original seat, the seat audio system no longer needs to play audio, so the audio channel connection between the original seat audio system and the original audio source device is severed.

[0088] If the passenger gets off the vehicle, the channel switching can be ended; if the passenger changes seats in the vehicle, the channel switching method of the seat audio can also include: obtaining the current seat audio corresponding to the current position information after the passenger's position information changes, and switching the channel of the current seat audio to the original sound source device.

[0089] The seat audio corresponding to the occupant's seat position information after the seat change is obtained, that is, the current seat audio corresponding to the current seat information, and the audio channel of the current seat audio is switched to the original sound source device. Although the occupant changes seats, the audio source device used generally does not change with the seat. For example, if the occupant is watching a video on the ceiling screen, they will continue to watch the video on the ceiling screen after changing seats, or if the occupant is using a mobile phone, they will continue to use the phone after changing seats. Therefore, the current seat audio after the occupant changes seats will still be switched to the original sound source device.
