[0027] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present application should fall within the scope of protection of the present application.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase at various points in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or opening relationships based on the positions or opening relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention; the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; in addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] As the level of automobile intelligence continues to improve, more and more private data of car owners is stored in the car. For example, during the use of the vehicle, the owner may answer or make calls, perform route navigation, store personal photos, etc. through the vehicle's on-board system. In these and other similar uses, the vehicle may record various aspects of the owner's private data. If no protective measures are taken, people other than the owner may easily view this private data, resulting in damage to the owner's privacy. In order to protect privacy, the owner may need to manually delete the private data of multiple functions in the car, which is a cumbersome process and reduces the user experience.

[0031] In order to better protect the privacy of car owners, especially in scenarios where multiple people or strangers are riding in the car, the embodiments of the present application support manual or automatic activation of the vehicle's owner privacy protection capabilities to automatically hide the privacy data of multiple functions of the vehicle, reducing user manual operations and improving the intelligent experience of using the car.

[0032] The following describes the embodiments of the present application with reference to the accompanying drawings to introduce the technical solution of the present application in more detail.

[0033] Figure 1 FIG. 1 is a schematic flow chart of a privacy protection method 100 provided in an embodiment of the present application. Figure 1As shown, the privacy protection method 100 may include steps S110 and S120.

[0034] In step S110 , a privacy protection activation command is received, wherein the privacy protection activation command is generated based on the recognition device identifying multiple persons and / or strangers riding in the vehicle, or is generated based on user input.

[0035] The privacy protection start command can be used to enable the vehicle to start a privacy protection operation. The privacy protection start command can be generated in various ways and can therefore have a corresponding form. For example, the privacy protection start command can be a specific control command generated by an identification device, a sensor, etc. when a specific condition is identified or detected, to control the vehicle control device (e.g., a vehicle system, a driving information and entertainment host (digital cockpit head unit, DHU)) to start a privacy protection operation (the privacy protection operation will be described in detail below). For example, in some embodiments, when the identification device (e.g., a visual recognition device, a sound recognition device, etc.) recognizes that multiple people are riding in the vehicle and / or strangers are riding in the vehicle, a corresponding control command can be generated to control the vehicle system to start a privacy protection operation. For another example, the privacy protection start command can be generated based on user input. The owner can provide user input in various ways. For example, user input can be provided through a vehicle-mounted central control screen, voice input, a mobile terminal, etc. For example, in some embodiments, the owner can manually select and click the privacy protection icon in the vehicle-mounted touch central control screen to generate a privacy protection start command so that the vehicle system starts a privacy protection operation.

[0036] It should be noted that the term "owner" mentioned in this application should be understood in a broad sense. For example, the owner may include a user who owns the vehicle and mainly drives the vehicle, a user who does not own the vehicle but is mainly responsible for driving the vehicle, or a user who does not own the vehicle but shares the vehicle key account. It should be understood that any user who has the right to drive the vehicle and needs to obtain privacy protection can be regarded as the owner mentioned in this application. Furthermore, it should be understood that in many driving scenarios, the owner acts as the driver and sits in the main driving position of the vehicle.

[0037] Multi-passenger ride refers to a scenario where more than two passengers ride together. When multiple people ride in a vehicle together, on the one hand, there may be a scenario where the driver and other passengers are not familiar with each other. At this time, if the driver directly answers or makes a Bluetooth call through the car system, the relevant phone information (for example, the identity of the caller, phone number, etc.) may be directly displayed on the car's central control screen, or the call voice content may be directly played through the car system. These are likely to lead to the leakage of the driver's privacy information. On the other hand, even if the driver and other passengers are familiar with each other, the driver may still not expect some privacy to be known by other passengers. For example, the driver and the co-driver are the male and female owners of the family, and the back seat is the children of the family. At this time, considering the protection of children, parents may not want some phone content to be known to children. Therefore, in the scenario of multiple passengers riding in a car, it is particularly easy to involve the privacy protection of the car owner (or driver).

[0038] In the embodiments of the present application, a multi-person vehicle scene can be identified by various means, and the privacy protection operation can be automatically started accordingly. For example, a multi-person vehicle scene can be identified by seat pressure sensors, visual recognition, sound recognition, seat belt usage, Bluetooth identification of electronic devices, etc. These identification means are introduced below.

[0039] Currently, vehicles are usually equipped with seat pressure sensors, which can be used to detect the number of passengers in the car. For example, in some embodiments, the seat pressure sensor can be used to detect whether there is someone on the seat. As an example, if the seat pressure sensor detects that the seat occupancy is equal to "someone", it means that the seat is occupied; if the seat pressure sensor detects that the seat occupancy is equal to "no one", it means that the seat is unoccupied. More specifically, for example, when the pressure detected by the seat pressure sensor is greater than a certain threshold (for example, 20kg), the seat is considered to be occupied by someone, otherwise it is unoccupied. Then, based on the seat occupancy detected by the pressure sensors of each seat in the car, the number of passengers in the car can be comprehensively counted to determine whether there are multiple passengers in the current car.

[0040] Optionally, in some embodiments, the vehicle may be equipped with a passive safety management (PSM) subsystem. The PSM subsystem may coordinate and control the pressure sensors of each seat in the vehicle, and obtain the number of passengers in the vehicle based on the seat occupancy detected by each pressure sensor. Furthermore, when it is determined that there are multiple passengers in the vehicle, the PSM subsystem may send relevant information to the vehicle system to trigger the vehicle to perform privacy protection operations.

[0041] Similar to the seat pressure sensor, the number of passengers in the car can also be determined based on the use of the seat belts. For example, if a seat belt is detected to be used, it can be considered that there is someone in the seat. Therefore, the number of passengers in the car can be determined based on the corresponding use of each seat belt in the car.

[0042] At present, vehicles are usually equipped with a camera device that can be used to detect the number of passengers in the car. For example, in some embodiments, the image of the passengers in the car can be taken by a vehicle-mounted camera device (for example, a camera integrated on the vehicle-mounted central control screen), so as to determine the number of passengers in the car. The number of passengers in the car can be obtained from the image of the passengers in the car, which can be achieved by various image recognition algorithms in the relevant technology, and this application is not limited to this. For example, the Haar feature cascade classifier, CamShift algorithm, density-based technical methods, deep learning target detection algorithms (for example, Faster R-CNN algorithm, YOLO (You Only Look Once) algorithm, SSD (Single Shot Detector) algorithm) and the like in the field of image recognition can be used to identify the number of passengers from the image of the passengers in the car. The specific content will not be repeated here.

[0043] Optionally, in some embodiments, the vehicle may be equipped with an occupancy monitoring system (OMS) for monitoring the status of passengers in the vehicle. The OMS system is usually equipped with an occupancy monitoring camera (OMC) that can be used to capture images of passengers in the vehicle. The OMS system can then identify the number of passengers in the vehicle based on the captured images. Furthermore, when the number of identified passengers is greater than 2, the OMS system can send relevant information to the vehicle system to trigger the vehicle to perform privacy protection operations.

[0044] In some embodiments, the number of passengers in the car can be determined by voice recognition. It is well known that each person usually has his or her own unique voice features (i.e., voiceprint features), such as spectral features, time domain features, resonance peak features, etc. Therefore, in some embodiments, the voice of passengers in the car can be collected by using a vehicle-mounted sound collection device (e.g., a microphone integrated on a central control screen or a rear TV screen (TV) (e.g., a ceiling TV, a backrest TV, etc.)), and then the voiceprint features of the voice can be analyzed by a certain data processing algorithm, and finally the number of passengers in the car can be identified according to different voiceprint features. As an example, passenger A and passenger B have different sound spectra. When passenger A speaks, the spectral feature A of passenger A is obtained through certain data processing (e.g., Fourier transform). When passenger B speaks, the spectral feature B of passenger B is similarly obtained. According to the different spectral features A and spectral features B, it can be identified that there are two different passengers, namely passenger A and passenger B. It should be understood that the recognition process here is only an example, and those skilled in the art can adopt different sound recognition processes according to specific needs to identify the number of passengers in the car.

[0045] In some embodiments, the number of passengers in the car can be determined by the Bluetooth identification of the passenger electronic device. The passenger electronic device refers to a personal electronic device carried by the passenger. It is well known that each electronic device usually has a unique Bluetooth identification. For example, the Bluetooth identification of the electronic device may include the device name (for example, iPhone 12, Garminwatch, etc.), manufacturer data (such as device model, brand, etc.), physical appearance data (for example, whether it is a mobile phone, watch, mouse, etc.), etc. In addition, each person usually carries only one mobile phone, one tablet or one electronic watch, etc. Therefore, for example, by detecting the Bluetooth identification of the electronic equipment in the car, it is possible to identify how many mobile phones, tablets, or electronic watches are currently in the car, thereby indirectly obtaining the number of passengers in the car.

[0046] As an example, several identification methods for multiple passengers are introduced above. However, it should be understood that those skilled in the art can easily think of other implementation methods to identify whether there are multiple passengers in the car, and this application does not limit this. For example, infrared detection methods can also be used to detect the number of heat sources in the car, thereby identifying whether there are multiple passengers in the car.

[0047] Strangers riding refers to the situation where there are strangers among the passengers in the car. The identity of "strangers" can be defined in various ways, and corresponding means can be used to achieve the identification of strangers riding. The following introduces two ways of defining the identity of strangers and their corresponding implementation means.

[0048] (1) Strangers can be limited by the car owner according to the specific situation

[0049] For example, the owner of a car can define all passengers other than himself as strangers. For another example, for a family car, the owner can define all passengers other than his family members as strangers. For another example, for a public vehicle, the owner can define all passengers other than those with vehicle driving authority, or all passengers other than those with vehicle key accounts, as strangers. The vehicle key account refers to a digital account corresponding to the vehicle, through which the user can remotely start the vehicle, lock / unlock the doors, turn on the air conditioner, and manage and control various other networking functions of the vehicle. It should be understood that the definition of strangers here is only an example, and those skilled in the art can easily think of other ways or logics to define strangers.

[0050] A variety of methods can be used to identify strangers defined by the car owner. For example, facial recognition technology can be used to identify strangers. As an example, in some embodiments, facial data of non-strangers defined by the car owner can be collected and stored in advance. Then, when facial recognition technology is used to identify facial features from the images of passengers in the car, the identified facial features can be compared with the pre-stored facial data. When there is no match with the pre-stored data, it is considered that there is a stranger in the car. For another example, similar to facial recognition technology, voiceprint recognition, Bluetooth identification of passenger electronic devices and other technologies can also be used to identify whether there are strangers in the vehicle, and this application does not limit this.

[0051] (2) The onboard control device can determine whether a stranger is a passenger based on the passenger’s frequency of riding.

[0052] Strangers can also be determined autonomously by the vehicle control device based on the frequency of passengers. For example, a threshold for the number of rides (e.g., 10 times) or a threshold for the frequency of rides (e.g., 5 times / month) can be pre-set. When the number of rides or the frequency of rides of a specific passenger is less than the corresponding threshold, the passenger is considered a stranger, otherwise not a stranger. By autonomously determining strangers, users can be freed from the inconvenience of manually defining strangers, and the definition of strangers can be dynamically adjusted to meet the needs of car owners in specific scenarios.

[0053] In order to obtain the frequency of passengers' rides, various passenger identification methods can be used. For example, each time the vehicle is started, an image of the passengers in the vehicle can be obtained, and the facial features of the passengers can be identified using, for example, facial recognition technology. Then, for the facial features obtained for the first time, the features can be stored, and the number of times the passenger has ridden can be recorded as 1. For facial features not obtained for the first time, the features can be matched with the already stored features to determine the corresponding passengers, and the number of times the matching passengers have ridden can be increased by 1. Thus, the frequency of passengers' rides can be obtained. It should be understood by those skilled in the art that other passenger identification methods, such as voiceprint recognition, Bluetooth identification of passenger electronic devices, etc., can also be used to identify passengers, so as to obtain the frequency of rides of different passengers.

[0054] Two ways of defining strangers and corresponding identification methods are introduced above. However, it should be understood that those skilled in the art can easily think of various other ways to define and identify strangers, and this application does not limit this.

[0055] Referring back to step S110, the user input may be obtained in various ways. For example, the driver may provide user input directly on the vehicle's central control screen to initiate the privacy protection operation. Figure 2 , showing the driver providing input through the vehicle "settings" on the main screen 210 of the vehicle's central control screen to start the privacy protection operation. Figure 2 As shown, the main screen 210 may include various applications or control entrances such as maps, phone, music, video, gallery, my vehicle, driving recorder, settings, etc. The driver can first select the "settings" icon to enter the settings interface. Then, see Figure 3 , shows a setting interface 310 generated after the user selects the "settings" icon. The setting interface 310 includes a user name and account, and a privacy mode tab 320. The user can select the privacy mode tab 320 to cause the vehicle to enter a proximity mode and perform a privacy protection operation.

[0056] Optionally, the user can also provide user input through the pull-down screen of the vehicle's central control screen to start the privacy protection operation. As an example, return to reference Figure 2 , the user can slide down from the top of the main screen 210 with a finger, so that the pull-down screen slides down from the top of the main screen 210. Then, the pull-down screen can display a privacy mode icon similar to the privacy mode tab 320. After the user selects the privacy mode icon on the pull-down screen, the vehicle can be prompted to enter the privacy mode and perform the privacy protection operation. Starting the privacy protection operation by pulling down the screen can save the driver's operating steps and improve the user's operating experience.

[0057] The above-mentioned method of providing user input on the central control screen is only an example. It should be understood that those skilled in the art can easily think of other software and / or hardware methods to help the driver complete the user input on the central control screen to start the privacy protection operation. This application does not limit this.

[0058] In addition to providing user input through the central control screen, user input can also be provided remotely through a mobile terminal to start the privacy protection operation. The mobile terminal can be any mobile terminal that can communicate remotely with the vehicle. For example, the mobile terminal can be a user's portable mobile terminal, such as a mobile phone, a tablet, a laptop, etc. For another example, in some embodiments, the mobile terminal can be a user's wearable device, such as a watch, a bracelet, etc. Figure 4 FIG. 4 is a schematic diagram of a mobile phone 400 provided in an embodiment of the present application. Figure 4 As shown, the mobile phone 400 may include a home screen 410. The home screen 410 may include multiple application icons such as file management, email, music, my vehicle 420, health, social, camera, address book, phone, information, etc. In the home screen 410, the user can select my vehicle 420 to control various remote control functions of the vehicle, such as privacy protection function, air conditioning function, and remote start function. After the user selects my vehicle 420, the user can select remote start of the vehicle and can find similar Figure 3 The settings page allows users to further remotely enable the vehicle privacy mode to start the vehicle's privacy protection operation.

[0059] In some embodiments, before the user remotely controls the vehicle, the user needs to first verify the user's identity. The user can verify his identity in various ways. For example, the user can enter his personal vehicle digital account and password to complete the identity verification. As another example, the user can perform face recognition to verify his identity. It should be understood that those skilled in the art can easily think of other identity verification methods, such as fingerprint recognition, gesture recognition, etc. This application is not limited to this. By remotely providing user input with the help of a mobile terminal to start the privacy protection mode, the owner's privacy data can be protected before the passengers enter the car, thereby providing the owner with better privacy protection effects.

[0060] As an example, two methods of providing user input are provided above. It should be understood that those skilled in the art can easily think of other methods to provide user input. For example, user input can also be provided by voice to enter the privacy mode and start the privacy protection operation. This application does not limit the method of providing user input.

[0061] Return to reference Figure 1In step S120, in response to receiving a privacy protection start command, a privacy protection operation is performed, wherein the privacy protection operation includes one or more of the following: Bluetooth privacy protection operation, phone privacy protection operation, vehicle navigation privacy protection operation, and vehicle application privacy protection operation. In some embodiments, a vehicle control system, such as a vehicle system, a DHU, etc., may receive a privacy protection start command and perform a privacy protection operation accordingly. It should be understood that for different vehicle models, a dedicated control device may be used to respond to a privacy protection start command and perform a privacy protection operation. This application does not limit this.

[0062] Traditionally, when the driver's mobile phone is wirelessly connected to the vehicle via Bluetooth, whenever the driver receives or makes a call, the caller ID (and / or the caller's name) will be displayed on the in-vehicle central control screen, and the call audio may be played externally when the driver is on the phone. However, these are likely to cause the driver's privacy to be leaked.

[0063] In order to protect the privacy of the driver when answering / making calls, in the embodiments of the present application, the telephone privacy protection operation may include various operations. For example, in some embodiments, the telephone privacy protection operation may include hiding call records, canceling the incoming call prompt screen on the central control screen, canceling the incoming call prompt tone, displaying the incoming call prompt screen on the instrument screen, and / or not playing the call sound inside and outside the car when answering the call. The instrument screen, also known as the dashboard or cockpit display, is a display screen located directly in front of the main driver. Since the instrument screen is usually only for the driver to view, displaying the incoming call prompt screen on the instrument screen can protect the driver's call privacy to a certain extent, and at the same time give the driver certain incoming call reminders so as not to miss the call. It should be understood that the telephone privacy protection operations listed above are only examples, and those skilled in the art can easily think of other ways to protect the driver's privacy information when answering / making calls.

[0064] The Bluetooth connection between the passenger's electronic device and the vehicle usually relies on various Bluetooth profiles, such as the hands-free profile (HFP), the advanced audio distribution profile (A2DP), etc. HFP allows passengers to answer and make calls through the vehicle's Bluetooth system without directly operating the terminal device (such as a mobile phone). A2DP is a profile used in Bluetooth technology to transmit high-quality audio (such as music). It can transmit audio content from the audio source device (such as a mobile phone, tablet, laptop, etc.) to the vehicle's audio system via Bluetooth for playback.

[0065] The Bluetooth privacy protection operation may include selectively using Bluetooth connections established based on various Bluetooth profiles. As an example, in some embodiments, when the Bluetooth connection between the passenger electronic device and the vehicle is initially established, the Bluetooth privacy protection operation may include: disabling the HFP-based connection while enabling the A2DP-based connection. For example, in some embodiments, when the Bluetooth connection between the passenger electronic device and the vehicle has been established, the Bluetooth privacy protection operation may include: disconnecting the HFP-based connection while maintaining the A2DP-based connection. Compared with the prior art, which generally defaults to using or not using the HFP-based and A2DP-based connections at the same time, through the embodiments of the present application, it is possible to receive and play audio files (such as music) through the vehicle-mounted system while answering and making calls without using the vehicle-mounted system, thereby not only protecting the privacy of the passengers, but also avoiding interfering with the passengers' entertainment activities, and ultimately taking into account the various needs of the passengers. Please note that the above embodiments are only examples, and those skilled in the art may also choose not to use the A2DP-based connection but to use the HFP-based connection according to actual needs. In addition, it should be noted that in addition to HFP and A2DP, the Bluetooth profile may also include a variety of other profiles, such as phone book access profile (PBAP) and message access profile (MAP), etc. Those skilled in the art may selectively use connections based on various profiles according to actual needs, thereby taking into account various needs of passengers.

[0066] The in-vehicle navigation privacy protection operation may include various operations. For example, in some embodiments, the in-vehicle navigation history records, favorite addresses, etc. of the owner may be hidden, thereby protecting the in-vehicle navigation privacy data of the owner.

[0067] The privacy protection operation of in-vehicle applications can cover various other applications related to the privacy of the car owner and the corresponding privacy protection operations. For example, in some embodiments, the gallery and / or camera applications can be disabled. For another example, in some embodiments, the local playback record of the audio and video entertainment application can be disabled. For another example, in some embodiments, the health application of the vehicle can be disabled to protect the owner's physical privacy information. It should be understood that these operations are only examples, and those skilled in the art can easily think of other privacy protection operations for in-vehicle applications. This application is not limited to this.

[0068] The above describes how to start the privacy protection operation of the vehicle and what privacy protection operations can be performed. However, in some cases, the driver may not realize or forget that the vehicle is already in privacy protection mode. In addition, at this time, the driver may still expect to make / receive a call via Bluetooth, but does not hear the external Bluetooth speaker, which may cause confusion.

[0069] In order to make it easier for the driver to know the privacy protection status of the vehicle, in some embodiments, after the vehicle starts to perform the privacy protection operation, the user can be prompted that the vehicle is in privacy protection mode so that the driver can understand the privacy status of the vehicle.

[0070] The vehicle can remind the driver that the vehicle is in privacy protection mode in various ways. For example, in some embodiments, the driver can be reminded that the vehicle is in privacy protection mode by voice. In another example, in some embodiments, a privacy mode on icon can be displayed on the instrument screen or the central control screen to remind the driver of the privacy protection status of the vehicle. As an example, Figure 5 A schematic diagram showing a privacy mode on-screen icon is shown in an embodiment of the present application. Figure 5 The main screen 510 of the central control screen is included. In the lower left corner of the main screen 510, a privacy mode is turned on icon 520 is included. Therefore, the driver can know that the vehicle is currently in the privacy protection mode according to the icon. It should be understood that the prompt method here is only an example, and those skilled in the art can easily think of other ways to prompt the privacy protection status of the vehicle. This application does not limit this.

[0071] Furthermore, when the privacy mode is turned on icon 520 is displayed on the central control screen, in some embodiments, the driver can exit the privacy protection mode by clicking on the icon. Therefore, when the user does not want privacy protection but wants to use a Bluetooth phone, the user can quickly exit the privacy protection mode by selecting the icon on the central control screen, thereby improving the user experience.

[0072] Return to reference Figure 1Before executing step S120, method 100 may further include the following steps: checking whether a precondition is satisfied. Here, the precondition refers to a condition that the vehicle needs to satisfy before executing privacy protection. For example, a vehicle may generally include a car mode (CM), a usage mode (UM) and a power mode (PM). Further, the CM mode may include, for example, a normal mode, a factory mode, a transport mode, a crash mode and a dyno mode. The UM mode may include, for example, an abandoned mode, an inactive mode, a convenience mode, an active mode and a driving mode. The PM mode may include, for example, an idle mode, an active mode and a driving mode. It is easy to understand that when the vehicle is in some specific modes, it is impossible, unnecessary or inappropriate to perform privacy protection operations. For example, when the vehicle is in a crash mode, it may be impossible or unnecessary to start the privacy protection mode. For another example, when the vehicle is in driving mode, considering that it is inconvenient for the driver to operate a mobile phone or other device to answer a call, many manufacturers do not recommend entering the privacy protection mode in driving mode, or default that the privacy protection mode cannot be entered in driving mode. Therefore, before executing step S120, it is possible to first check whether the vehicle meets the preconditions.

[0073] Figure 6 FIG. 6 is a schematic diagram showing an overall process 600 provided by an embodiment of the present application. Figure 6 As shown, process 600 may include steps S610 - S670 .

[0074] In step S610, it is checked whether the vehicle meets the preconditions. Note that the vehicle preconditions of different vehicles may be different and should be determined according to the specific situation.

[0075] If the answer is yes in step S610, the process proceeds to step S620, where a pop-up window is displayed for the driver to confirm whether to perform the privacy protection action.

[0076] In case of No in step S610, the process proceeds to step S650, where the action cannot be performed and a prompt is given, such as a text prompt (also known as a classical Chinese prompt).

[0077] If the answer is yes in step S620, proceed to step S640, execute the privacy protection function and the process ends.

[0078] If the answer is No in step S620, the process proceeds to step S660 without performing any action.

[0079] Through process 600, it can be ensured that the vehicle privacy protection operation is performed only when the vehicle meets the preconditions, thereby ensuring the robustness of the vehicle privacy protection function.

[0080] The vehicle state may change, for example, the vehicle mode changes rapidly from ignition to start of driving. At this time, after step S620, the vehicle state may have changed, causing the vehicle to no longer meet the preconditions, and the privacy protection function may be abnormally exited, resulting in a poor user experience.

[0081] To further improve the robustness of process 600 , in some embodiments, overall process 600 may further include steps S630 and S670 .

[0082] In step S630, it is checked again whether the vehicle meets the preconditions.

[0083] In case of No in step S630, the process proceeds to step S670, where the action cannot be performed and a prompt is given.

[0084] If the answer is yes in step S630, proceed to step S640, execute the privacy protection function and the process ends.

[0085] Optionally, in some embodiments, the vehicle control device (e.g., vehicle system, driving information and entertainment host) can memorize the privacy settings of the vehicle when the ignition was last turned off. Thus, when the vehicle is restarted, the vehicle control device can automatically restore the previous privacy settings to maintain the previous privacy protection state.

[0086] Optionally, in some embodiments, tracking points can be set in advance so that when the user activates / exits the privacy protection function through the central control screen, mobile terminal (such as a mobile phone), voice, etc., the operation entry and function / failure parameters can be reported, which is conducive to improving user input operations based on the various reported parameters and improving the robustness of the system.

[0087] For the convenience of understanding the present application, the present application embodiment is described in more detail below in conjunction with specific examples. It should be noted that this example is only to help those skilled in the art understand the present application embodiment, rather than to limit the present application embodiment to the illustrated specific numerical value or specific scenario. Those skilled in the art can obviously make various equivalent modifications or changes according to the examples given below, and such modifications or changes also fall within the scope of the present application embodiment.

[0088] 1. Functional Overview & Value

[0089] When multiple people are in a vehicle, there may be scenarios where the driver and other passengers are unfamiliar with each other. In order to protect the privacy of the driver, such as Bluetooth phone calls and in-car navigation, a privacy protection function is proposed to enhance the driver's intelligent experience. The privacy protection function involves the development of driving information and entertainment host (Digital Cockpit Head Unit, DHU) and mobile phone terminals.

[0090] 2. Functional Description

[0091] The states that can be set include: multi-passenger intelligent protection and strangers' intelligent protection. These two functions are set to off by default when leaving the factory. They can be switched, remember the user's last selection, and are only triggered once in a driving cycle. Among them, the vehicle from ignition to shutdown is considered a driving cycle.

[0092] Detect whether the seat is occupied. For example, the passive safety management (PSM) system can provide feedback on whether the seat is occupied: if the seat is occupied = occupied, the seat is considered to be occupied; if the seat is occupied ≠ occupied, the seat is considered to be unoccupied.

[0093] Detect whether there are strangers in the car. The occupancy monitoring camera (OMC) can be used to identify whether the front passenger and rear passengers are non-car owners or people who share key accounts. If not, the passengers are considered strangers.
