Description

Technical Field

[0001] The present invention relates to the field of smart driving cabins, and in particular to a vehicle-mounted Bluetooth management method, system, state manager and storage medium. Background Art

[0002] Bluetooth technology is an open global specification for wireless data and voice communications. Its essence is to establish a universal radio air interface for the communication environment between fixed or mobile devices, further combining communication technology with computer technology, so that various 3C devices can communicate or operate with each other in a short range without being connected by wires or cables. Car Bluetooth is an in-car wireless hands-free system designed and developed based on wireless Bluetooth technology. Its main function is to use Bluetooth technology to connect to a mobile phone for hands-free calls during normal driving, thereby freeing your hands and reducing the risk of traffic accidents.

[0003] Currently, there are two problems with car Bluetooth: 1. When a mobile phone is connected to the car Bluetooth, if you suddenly get off the car while answering a Bluetooth call, the call is not hung up and the sound is still in the car, which reduces the user's calling experience and may leak privacy; 2. The owner leaves the car, but the phone remains in the car, and there is a lack of omission reminder.

[0004] Among the existing known methods, there is a method of checking whether the car owner has left the driving seat and switching the Bluetooth call to a private mode, but this method only detects whether the car owner has left the seat through a sensor, and does not detect whether the mobile phone follows the car owner when he leaves the seat, nor does it detect whether the currently connected mobile phone is the car owner's mobile phone. If the connected user is not the driver, this method is invalid. This method only switches the Bluetooth private mode, and the sound can still be switched back to the car computer in the actual car, which does not achieve the effect of privacy protection. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a vehicle-mounted Bluetooth management method, system, state manager and storage medium, which can realize the disconnection or connection, automatic loss reminder and automatic left behind reminder of the communication terminal in Bluetooth mode, while not affecting the normal use of the user, improving the user experience.

[0006] The present invention provides a vehicle-mounted Bluetooth management method, comprising:

[0007] S100: When the vehicle end is connected to the communication terminal via Bluetooth, a first relative position between the vehicle user and the vehicle end is obtained, and a second relative position between the communication terminal and the vehicle end is obtained.

[0008] S200: Determine a Bluetooth status management mode according to the first relative position and the second relative position to manage the vehicle-mounted Bluetooth; the Bluetooth status management mode includes at least: a first management mode, a second management mode and a third management mode.

[0009] Preferably, the communication terminal may be any one of a mobile phone, a tablet or a mobile communication device, but is not limited thereto.

[0010] Furthermore, the obtaining of the first relative position between the vehicle user and the vehicle terminal further includes: obtaining image information of a seat in the vehicle; performing face recognition on the image information to determine whether a face is recognized on the seat in the vehicle cabin, and if so, determining that the vehicle user is in the vehicle cabin; otherwise, determining that the vehicle user is outside the vehicle cabin;

[0011] The first relative position between the current vehicle user and the vehicle terminal is recorded; the vehicle users include at least: a target user and other users.

[0012] Preferably, the vehicle users are the driver, the co-pilot, the left rear passenger and the right rear passenger, wherein the target user is the user of the communication terminal connected to the vehicle via Bluetooth, and the other users are other passengers in the vehicle; in most cases, the target user is the driver or the co-pilot, and the other passengers are the left rear passenger and the right rear passenger; the examples below are mainly for the case where the user of the communication terminal is the driver.

[0013] Among them, the DMS (Driver Monitoring System) camera is used to detect whether the driver has left the driving seat, and the OMS (Occupancy Monitoring System) camera is used to detect whether the co-pilot has left the driving seat.

[0014] Furthermore, obtaining the second relative position of the communication terminal and the vehicle end also includes: obtaining the current Bluetooth signal strength of the communication terminal; when the current Bluetooth signal strength of the communication terminal is greater than or equal to the preset Bluetooth signal strength, it is determined that the communication terminal is in the cabin, otherwise, it is determined that the communication terminal is outside the cabin; and recording the current second relative position of the communication terminal and the vehicle end.

[0015] Preferably, the current Bluetooth signal strength of the communication terminal is obtained through a Bluetooth module antenna. Furthermore, the antenna can be placed inside the vehicle and at the positions of the left and right door handles.

[0016] Further, determining the Bluetooth state management mode according to the first relative position and the second relative position specifically includes:

[0017] When the target user is outside the cabin and the communication terminal is outside the cabin, the first management mode is entered; the first management mode includes: disconnecting the Bluetooth connection between the vehicle end and the communication terminal, and when the communication terminal returns to the cabin, the vehicle end and the communication terminal are connected to the Bluetooth connection.

[0018] When the target user is outside the vehicle cabin and the communication terminal is inside the vehicle cabin, the second management mode is entered; the second management mode includes: sending an alarm message to the vehicle terminal and reminding the target user through a loudspeaker that the mobile phone is left in the vehicle.

[0019] When the target user is in the cabin, the third management mode is entered; the third management mode includes: determining whether the other passengers are outside the cabin, and if so, sending a loss message to the vehicle end, and reminding the target user through the screen that the communication terminal is lost; otherwise, returning to S100.

[0020] It should be understood that the first management mode can be applied to when a mobile phone connected to the vehicle via Bluetooth is in a call state, so that the user can automatically disconnect from the vehicle when getting off the vehicle, thereby protecting the user's privacy.

[0021] During the specific implementation process, the above three management modes can be realized by designing a state management module. Please refer to the following example program.

[0022] Design a class StateManager as follows:

[0023] class StateManager {

[0024] public static final int DRIVER = 0; / / Driver

[0025] public static final int R_F_OCCUPANCY = 1; / / Co-pilot

[0026] public static final int L_R_ OCCUPANCY = 2; / / Left rear passenger

[0027] public static final int R_R_OCCUPANCY = 3; / / Right rear passenger

[0028] public int[4] mUserState; / / Detect up to 4 user states and associate DMS and OMS cameras

[0029] public int mBtState; / / Bluetooth status

[0030] / / The driver and the phone leave the car at the same time

[0031] public Boolean isDriverAndBtLeave() {

[0032] return mUserState[DRIVER] == 1 && mBtState == 1;

[0033] }

[0034] / / The driver leaves but the phone does not leave

[0035] public Boolean isDriverLeaveButBtInCar() {

[0036] return mUserState[DRIVER] == 1 && mBtState != 1;

[0037] }

[0038] / / Phone was stolen

[0039] public Boolean isBtLose() {

[0040] return mBtState == 1 && mUserState[DRIVER] == 0 &&

[0041] (mUserState[R_F_OCCUPANCY] == 1 ||

[0042] mUserState[L_R_OCCUPANCY] == 1 ||

[0043] mUserState[R_R_OCCUPANCY] == 1);

[0044] }}

[0045] Based on this, the above three management modes are implemented as examples:

[0046] The first management mode: The DMS camera detects that the owner has left the driving seat, and the DMS camera sends a signal to the status management module. When the door is closed, the Bluetooth antenna on the door handle detects that the currently connected mobile phone has left the car. At this time, the Bluetooth module will send a message to the host that the mobile phone has left the car.

[0047] The status at this time is as follows: mUserState[DRIVER] = 1; mBtState = 1; isDriverAndBtLeave() == true;

[0048] Among them, after the status management module receives the message sent by the Bluetooth module, it also receives the message from the DMS module that the car owner has left the driving seat. It detects that a Bluetooth call is in progress at this time and directly disconnects the current Bluetooth. At this time, the Bluetooth module is directly disconnected and the sound will be directly switched back to the mobile phone, allowing the user to hear the call sound directly on the mobile phone, which not only protects the user's privacy but also improves the user experience.

[0049] Second management mode: The DMS camera detects that the owner has left the driver's seat. The DMS camera sends the signal that the owner has left the driver's seat to the status management module. When the door is closed, the Bluetooth antenna on the door handle does not detect that the currently connected mobile phone has left the car with the owner. At this time, the status is as follows: mUserState[DRIVER] = 1; mBtState = 0; isDriverLeaveButBtInCar() == true;

[0050] When the status management receives the door closing message, it detects isDriverLeaveButBtInCar() == true and thinks that the driver has left the car and forgotten his phone. The status management module sends an alarm message to the original car and sounds an alarm through the horn to remind the user that the phone is left in the car.

[0051] The third management mode: The DMS camera does not detect that the owner has left the driver's seat, and mUserState[DRIVER] = 0; the OMS camera detects that the co-pilot has left the co-pilot seat, and mUserState[R_F_OCCUPANCY] = 1; when the co-pilot door is closed, the Bluetooth antenna on the door handle detects that the currently connected mobile phone has left the car with the co-pilot, and the Bluetooth status is as follows, mBtState = 1;

[0052] When the status management receives the door closing message and detects isBtLose() == true, the status management module will think that the phone is lost and will issue a warning on the cockpit entertainment system screen to remind the driver that your phone has left the car. Please confirm whether it is lost, reducing unnecessary trouble for the car owner.

[0053] As another preferred embodiment, the present invention further provides a vehicle-mounted Bluetooth management system, the system at least comprising:

[0054] The first acquisition module is used to obtain a first relative position between the vehicle user and the vehicle terminal.

[0055] The second acquisition module is used to obtain a second relative position between the communication terminal and the vehicle end.

[0056] And a state management module determines a Bluetooth state management mode according to the first relative position and the second relative position to achieve management of the vehicle-mounted Bluetooth.

[0057] Furthermore, the first acquisition module is communicatively connected to the Bluetooth module antenna, obtains the current Bluetooth signal strength of the communication terminal through the Bluetooth module antenna, and determines whether the communication terminal is inside or outside the cabin according to the current Bluetooth signal strength of the communication terminal.

[0058] The second acquisition module is communicatively connected to the vehicle-mounted camera, and acquires image information of the seats in the vehicle through the vehicle-mounted camera. It determines whether the vehicle user in the current seat is inside or outside the cabin according to whether the face is recognized in the image information.

[0059] Furthermore, the state management module specifically includes:

[0060] The first management module is used to control the Bluetooth connection or disconnection between the vehicle end and the communication terminal.

[0061] The second management module is used to send an alarm message to the vehicle end, and remind the target user through the speaker that the mobile phone is left in the car.

[0062] The third management module is used to send the lost information to the vehicle end and remind the target user through the screen that the mobile phone is lost.

[0063] As another preferred embodiment, the present invention also provides a state manager, which is used to determine the vehicle Bluetooth state management mode according to the relative positions of the vehicle personnel, the communication terminal and the vehicle, so as to manage the vehicle Bluetooth. The state manager is the state management module in the system as described above.

[0064] As another preferred embodiment, the present invention further provides a storage medium located in any control unit, wherein the storage medium includes a computer program executable by a processor, and the computer program is used to execute the in-vehicle Bluetooth management method as described above.

[0065] Compared with the prior art, the beneficial effects of this solution are:

[0066] The present invention discloses a vehicle-mounted Bluetooth management method, system, state manager and storage medium, and realizes three management modes through a state management module. The first management mode can automatically control the Bluetooth connection or disconnection between the vehicle end and the communication terminal, the second management mode can realize automatic reminder when the communication terminal is lost, and the third management mode can realize automatic reminder when the communication terminal is left behind. Various mode switching can be realized without manual operation by the user, thereby improving the user experience without affecting the normal use of the user. BRIEF DESCRIPTION OF THE DRAWINGS
