[0062] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0063] In this application, the terms "first", "second", etc. are used to distinguish the same or similar items with substantially the same role and function. It should be understood that there is no logical or temporal dependency between "first", "second", and "nth", nor is there a limitation on the quantity and execution order. It should also be understood that although the following description uses the terms first, second, etc. to describe various elements, these elements should not be limited by the terms.

[0064] These terms are only used to distinguish one element from another element. For example, without departing from the scope of various examples, a first element can be referred to as a second element, and similarly, a second element can also be referred to as a first element. Both the first element and the second element can be elements, and in some cases, can be separate and different elements.

[0065] Here, at least one means one or more than one, for example, at least one element can be one element, two elements, three elements, or any other integer greater than or equal to one. And multiple means two or more than two, for example, multiple elements can be two elements, three elements, or any other integer greater than or equal to two.

[0066] The "and / or" mentioned in this article indicates that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects before and after are in an "or" relationship.

[0067] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards in the relevant regions.

[0068] Figure 1 It is a schematic diagram of the architecture of an in-vehicle Bluetooth control system provided in an embodiment of the present application.

[0069] See also Figure 1 The system includes: OMS1 (Occupancy Monitoring System), user management module 2, network database 3 and vehicle-mounted Bluetooth control module 4. OMS1 includes camera 11 and processing module 12.

[0070] In the embodiment of the present application, the camera 11 is used to collect the biometric information of the passengers. Among them, the camera 11 is a vehicle-mounted camera, such as a driver monitoring camera, a front-row camera in the car, or a rear-row camera in the car, which is not limited in the present application. In addition, the biometric information mentioned in this article includes but is not limited to facial information, which is also not limited in the present application. The processing module 12 is used to process the biometric information collected by the camera 11, such as pre-processing the collected facial information to extract effective facial features and reduce the influence of interference factors, thereby improving the accuracy of facial recognition. The user management module 2 is used to perform user identity identification and can communicate data with the network database 3. Among them, the network database 4 is used to store the user's biometric information in the cloud. For the vehicle-mounted Bluetooth control module 4, it is used to establish or disconnect the Bluetooth communication connection between the vehicle machine and the mobile terminal used by the user according to the identity identification result output by the user management module 2.

[0071] As an example, taking the biometric information as facial information, the network database 3 stores the facial information of the car owner, and the camera 11 is responsible for collecting the facial information of the person in the main driving position, after the user unlocks the door and gets in the car, the camera 11 will collect the driver's facial information and send the collected facial information to the processing module 12. After processing the collected facial information, the processing module 12 will send the processed facial information to the user management module 2 through the vehicle-mounted local area network.

[0072] After receiving the processed face information, the user management module 2 will obtain the face information from the network database 3, and perform user identity recognition based on the processed face information and the face information stored in the network database 3 to determine whether the current driver is the car owner, and send the identity recognition result to the vehicle-mounted Bluetooth control module 4. If the identity recognition result indicates that the car owner is sitting in the main driving position, the vehicle-mounted Bluetooth control module 4 will control the automatic establishment of a Bluetooth communication connection between the vehicle computer and the mobile terminal used by the driver, that is, automatically switch the Bluetooth focus to the vehicle computer.

[0073] In addition, if the OMS detects that the owner has left the main driving position, then under certain conditions, the vehicle-mounted Bluetooth control module 4 will control the vehicle computer to automatically disconnect the Bluetooth communication connection with the mobile terminal, that is, switch the Bluetooth focus back to the mobile terminal. In addition, if the identity recognition fails or the identity recognition result indicates that the owner is not sitting in the main driving position, the operation of establishing a Bluetooth communication connection between the two will not be actively performed.

[0074] Figure 2 is a flow chart of a method for controlling the connection of in-vehicle Bluetooth provided in an embodiment of the present application. The execution subject of the method is Figure 1 The car's Bluetooth control system is shown. Figure 2 The method flow includes:

[0075] 201. After the vehicle door switches from a locked state to an unlocked state, the vehicle-mounted Bluetooth control system collects biometric information of the passengers.

[0076] This step is done by Figure 1 In addition, the passengers in this step can be the passengers in the main driving position, the passengers in the co-pilot position, the passengers in the back seat of the car, or even all the passengers in the car, and this application does not limit this.

[0077] As an example, the collected biometric information is facial information, wherein the facial information can be either a static image taken by the camera 11 or an image frame captured from a dynamic video taken by the camera 11, and this application does not limit this.

[0078] 202. The vehicle-mounted Bluetooth control system identifies the identity of the passengers based on the collected biometric information and the network database; wherein the network database stores the biometric information of the target user.

[0079] This step is done by Figure 1 The processing module 12 and the user management module 2 shown in are executed.

[0080] As an example, the processing module 12 is used to preprocess the biometric information collected by the camera 11. The preprocessing includes but is not limited to size adjustment, posture correction, illumination adjustment, noise filtering, color normalization or grayscale processing, etc., which is not limited in this application.

[0081] In the embodiment of the present application, the biometric information stored in the network database 3 is pre-entered. That is, the target user is a pre-set user, such as a car owner. After the target user pre-enters his or her biometric information, the pre-entered biometric information will be stored in the cloud, that is, in the network database 3, to facilitate subsequent user identification and reduce the data storage pressure on the vehicle side.

[0082] As an example, assuming that the collected biometric information is face information, the user management module 2 mainly includes the following key links when performing user identity recognition: face detection, feature extraction and face comparison. Among them, face detection is used to determine the position and size of the face. Feature extraction is used to perform in-depth analysis of the face part after the face is detected, and extract the features of the face, such as the position of the facial features, facial expressions, whether glasses are worn, etc. Face comparison is to compare the extracted features with the features of the face information stored in the network database to determine the user's identity.

[0083] 203. If the collected biometric information matches the biometric information stored in the network database, the vehicle-mounted Bluetooth control system determines that the target user is included in the vehicle passengers, and sets the Bluetooth communication connection between the vehicle computer and the mobile terminal used by the target user to a connected state.

[0084] In the embodiment of the present application, when the number of passengers is one, the above-mentioned determination that the passengers include the target user means: determining the passenger as the target user.

[0085] As an example, taking the collected biometric information as facial information and the target user as the car owner, if the collected facial information matches the facial information stored in the network database, it is determined that the car owner is included in the passengers, and the on-board Bluetooth control system will set the Bluetooth communication connection between the car computer and the mobile terminal used by the car owner to a connected state, that is, establish a Bluetooth communication connection between the car computer and the mobile terminal used by the car owner.

[0086] It should be noted that the implementation premise of this step is that the Bluetooth switch of the mobile terminal used by the car owner has been turned on.

[0087] 204. After the target user gets off the vehicle, if the distance moved by the target user does not exceed the Bluetooth connection range and the Bluetooth disconnection condition is currently met, the vehicle-mounted Bluetooth control system sets the Bluetooth communication connection between the vehicle computer and the mobile terminal to a disconnected state.

[0088] Among them, the Bluetooth connection range refers to the maximum connection distance of Bluetooth. If this distance is exceeded, the Bluetooth connection between devices will be disconnected.

[0089] In some embodiments, the above Bluetooth disconnection conditions include but are not limited to:

[0090] 1. The target user gets off the bus holding a mobile terminal, and the mobile terminal is currently in a voice call state.

[0091] This situation corresponds to the scenario where the target user gets off the car to make a phone call. In order to protect the user's personal privacy, the Bluetooth communication connection between the car computer and the mobile terminal needs to be disconnected.

[0092] 2. The target user’s getting off time exceeds the time threshold.

[0093] This situation corresponds to the scenario where the target user gets off the vehicle for a long time. The duration threshold may be 5 minutes or 10 minutes, etc., and this application does not limit this. In addition, if the target user's getting off the vehicle does not exceed the duration threshold, it corresponds to the scenario where the target user gets off the vehicle for a short time, and at this time, the Bluetooth communication connection between the vehicle computer and the mobile terminal needs to be maintained.

[0094] In summary, the embodiments of the present application achieve precise connection control of the vehicle-mounted Bluetooth. For example, after a person gets on the bus, a Bluetooth communication connection will not be directly established between the vehicle computer and the mobile terminal used by the passenger. Instead, the passenger will be identified first, and only after the identity is identified, a Bluetooth communication connection will be established between the vehicle computer and the mobile terminal. For another example, after a person gets off the bus, even if the mobile terminal does not exceed the Bluetooth connection range at this time, after determining that the user does not need to use Bluetooth at this time, the Bluetooth communication connection between the two will still be automatically disconnected. This connection control method enables flexible and accurate use of vehicle-mounted Bluetooth, reduces user manual operations, and saves labor costs.

[0095] Figure 3 1 is a flow chart of another in-vehicle Bluetooth connection control method provided by an embodiment of the present application. The execution subject of the method is a computer device, such as Figure 1 The car's Bluetooth control system is shown. Figure 3 The method flow includes:

[0096] 301. After the vehicle door is switched from a locked state to an unlocked state, the vehicle-mounted Bluetooth control system collects biometric information of the passengers.

[0097] In some embodiments, to avoid Figure 1 The camera 11 shown performs non-essential shooting. The embodiment of the present application collects biometric information of passengers in the following manner:

[0098] The seats at various positions in the car are detected to obtain seat occupancy information; if the seat occupancy information indicates that the seat at the target position is occupied, the biometric information of the passenger sitting in the seat at the target position is collected.

[0099] The target position may be a pre-set seat position, such as the main driving position, or any seat position in the vehicle, which is not limited in this application.

[0100] 302. The vehicle-mounted Bluetooth control system identifies the passenger based on the collected biometric information and the network database; wherein the network database stores the biometric information of the target user.

[0101] This step may refer to the above step 202 and will not be described again here.

[0102] 303. If the collected biometric information matches the biometric information stored in the network database, the vehicle-mounted Bluetooth control system determines that the target user is included in the vehicle passengers, and sets the Bluetooth communication connection between the vehicle computer and the mobile terminal used by the target user to a connected state.

[0103] This step may refer to the above step 203 and will not be described again here.

[0104] 304. After the target user gets off the vehicle, if the distance moved by the target user does not exceed the Bluetooth connection range and the Bluetooth disconnection condition is currently met, the vehicle-mounted Bluetooth control system sets the Bluetooth communication connection between the vehicle computer and the mobile terminal to a disconnected state.

[0105] This step may refer to the above step 204 and will not be described in detail here.

[0106] 305. If the collected biometric information does not match the biometric information stored in the network database, it is determined that the target user is not included in the passengers, and the vehicle-mounted Bluetooth control system sets the Bluetooth communication connection between the vehicle computer and the mobile terminal to a disconnected state.

[0107] As an example, taking the collected biometric information as facial information and the target user as the car owner, if the collected facial information does not match the facial information stored in the network database, it is determined that the car owner is not included in the passengers, and the on-board Bluetooth control system will set the Bluetooth communication connection between the car computer and the mobile terminal used by the car owner to a disconnected state, that is, no Bluetooth communication connection is established between the car computer and the mobile terminal used by the car owner, or the previously established Bluetooth communication connection is disconnected.

[0108] In some embodiments, when there are multiple passengers, the method provided in the embodiment of the present application also includes: if the mobile terminal that has established a Bluetooth communication connection with the vehicle computer switches from an audio playback state to a voice call state, the vehicle-mounted Bluetooth control system will control the Bluetooth communication connection between the two to switch from a connected state to a sleep state. Among them, the sleep state refers to a state in which the Bluetooth communication connection between the two is not disconnected but a voice call is not made through the vehicle computer. After the voice call is over, the vehicle-mounted Bluetooth control system will control the Bluetooth communication connection between the two to switch from a sleep state to a connected state, and output the audio played by the mobile terminal through the vehicle computer. For example, according to the playback progress before the interruption of playback, the audio played by the mobile terminal continues to be output through the vehicle computer. Among them, the audio played can be music, audio books or audio novels, etc., which are not limited in this application.

[0109] In other embodiments, after the Bluetooth communication connection between the vehicle computer and the mobile terminal is set to a connected state, the method provided in the embodiment of the present application further includes the following optimization strategy:

[0110] Preprocess the facial information collected after the status setting is completed; based on the preprocessed facial information, perform emotion recognition on the passenger to obtain an emotion recognition result; if the emotion recognition result indicates that the passenger is dissatisfied with the current status setting, such as recognizing that the passenger's emotion type is a negative emotion, then switch the Bluetooth communication connection between the two from a connected state to a disconnected state.

[0111] As an example, based on the pre-processed facial information, emotion recognition is performed on passengers to obtain emotion recognition results, including but not limited to the following methods:

[0112] Based on the pre-processed facial information, emotions of passengers are recognized to obtain preliminary emotion recognition results; the driving environment data outside the vehicle and the driving environment data inside the vehicle are obtained; according to the driving environment data outside the vehicle and the driving environment data inside the vehicle, the preliminary emotion recognition results are corrected to obtain final emotion recognition results.

[0113] Exemplarily, the emotion recognition of passengers can be performed by inputting the pre-processed facial information into the emotion recognition model. The emotion recognition model can be a deep learning model, which is not limited in this application. In addition, the driving environment data outside the vehicle includes but is not limited to: traffic congestion data, weather data or lighting data, etc.; the driving environment data inside the vehicle includes but is not limited to: noise data, temperature data or humidity data, etc. It should be noted that the correction step is mainly used to determine whether the negative emotions expressed by the passengers are caused by the driving environment outside the vehicle or the driving environment inside the vehicle, so as to more accurately determine whether the passengers are satisfied with the current status settings.

[0114] In summary, the embodiments of the present application achieve precise connection control of the vehicle-mounted Bluetooth. For example, after a person gets on the bus, a Bluetooth communication connection will not be directly established between the vehicle computer and the mobile terminal used by the passenger. Instead, the passenger will be identified first, and only after the identity is identified, a Bluetooth communication connection will be established between the vehicle computer and the mobile terminal. For another example, after a person gets off the bus, even if the mobile terminal does not exceed the Bluetooth connection range at this time, after determining that the user does not need to use Bluetooth at this time, the Bluetooth communication connection between the two will still be automatically disconnected. This connection control method enables flexible and accurate use of vehicle-mounted Bluetooth, reduces user manual operations, and saves labor costs.

[0116] See also Figure 4 , the device comprises:

[0117] The collection unit 401 is configured to collect biometric information of passengers after the door is switched from a locked state to an unlocked state;

[0118] The identification unit 402 is configured to identify the passenger based on the collected biometric information and a network database; wherein the network database stores the biometric information of the target user;

[0119] The control unit 403 is configured to determine that the target user is included in the vehicle passengers if the collected biometric information matches the biometric information stored in the network database, and set the Bluetooth communication connection between the vehicle computer and the mobile terminal used by the target user to a connection state;

[0120] The control unit 403 is further configured to set the Bluetooth communication connection between the vehicle and the mobile terminal to a disconnected state after the target user gets off the vehicle if the distance moved by the target user does not exceed the Bluetooth connection range and the Bluetooth disconnection condition is currently met.

[0121] The embodiments of the present application realize precise connection control of the vehicle-mounted Bluetooth. For example, after a person gets on the vehicle, a Bluetooth communication connection will not be directly established between the vehicle computer and the mobile terminal used by the passenger. Instead, the passenger will be identified first, and only after the identity is identified, a Bluetooth communication connection will be established between the vehicle computer and the mobile terminal.
