Description

Technical Field

[0001] The present application relates to the field of vehicle control, and more specifically, to a method, device, vehicle and storage medium for controlling a vehicle tailgate in the field of vehicle control. Background Art

[0002] The trunk of a vehicle is a storage space for users to store items. When users need to open the back door of the trunk to store or access items, there are several common ways to open the back door, including key opening, switch opening, sensor opening, and remote opening. The above-mentioned back door opening methods require the owner to be close to the vehicle.

[0003] In the related art, when someone other than the vehicle owner needs to store or retrieve items in the vehicle trunk, the vehicle owner is required to first open the tailgate using the above-mentioned opening methods, which makes the tailgate opening method not flexible enough and leads to a poor user experience. Summary of the invention

[0004] The present application provides a method, device, vehicle and storage medium for controlling the tailgate of a vehicle. The method can eliminate the need for the owner to open the tailgate when a non-owner user needs to temporarily open the tailgate, thereby improving the convenience and flexibility of opening the tailgate, saving the owner from unnecessary trouble and improving the user experience.

[0005] In a first aspect, a method for controlling a tailgate of a vehicle is provided, the method comprising: when the tailgate of the vehicle is closed, obtaining a target control parameter of the tailgate and sending the target control parameter to a terminal device of a target user, the target control parameter being used to indicate an action that the target user needs to perform to open the tailgate, and a control duration of the tailgate by the target user; in response to an actual control parameter of the target user, determining whether the actual control parameter is consistent with the target control parameter; and when the actual control parameter is consistent with the target control parameter, controlling the tailgate to open.

[0006] In the above technical solution, when the back door of the vehicle is closed, the present application proposes a method for controlling the back door of the vehicle. In the specific implementation process of the method, when the back door of the vehicle is closed, the vehicle can obtain the target control parameter of the current back door and send it to the terminal device of the target user. Further, the vehicle determines whether the actual control parameter is consistent with the target control parameter by receiving the actual control parameter executed by the target user based on the target control parameter. When the actual control parameter is consistent with the target control parameter, the back door of the vehicle is controlled to open. When the actual control parameter is inconsistent with the target control parameter, the back door of the vehicle is controlled to close. In the above process of opening the back door, the owner user does not need to control the back door to open by using a key or a back door switch. Therefore, when the back door needs to be opened, even if the owner user is not near the vehicle, the vehicle can also open the back door by parameter matching when the parameter matching is detected to be successful, which not only improves the flexibility and convenience of opening the back door, but also takes into account the safety when the back door is opened, reduces unnecessary troubles for the owner user, and improves the user experience.

[0007] In combination with the first aspect, in some possible implementations, after controlling the opening of the back door, the method also includes: during the opening process of the back door, determining whether the interior environment of the vehicle is abnormal through the interior environment video collected by the interior camera; when the interior environment of the vehicle is abnormal, generating a first alarm message and controlling the closing of the back door based on the interior environment; when there is no abnormality in the interior environment of the vehicle, determining whether the target control parameter is invalid based on the target control parameter and the actual control parameter.

[0008] In the above technical solution, when the back door is opened, in order to ensure the safety of the property in the car, the vehicle can monitor the interior environment in real time through the in-car camera, so as to timely detect whether the interior environment is abnormal. When the interior environment is abnormal, the vehicle can generate a first alarm message and immediately close the back door. When the back door is opened, the above abnormal interior environment is detected in a timely and effective manner, and the owner can be informed in time through the alarm, so that the owner can check and deal with it in time.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the target control parameter includes a target control duration, and the actual control parameter includes an actual control duration. The method of determining whether the target control parameter is invalid is based on the target control parameter and the actual control parameter, including: when the actual control duration is less than the target control duration, determining that the target control parameter is not invalid; when the actual control duration is greater than or equal to the target control duration, controlling the back door to close and determining that the target control parameter is invalid.

[0010] In the above technical solution, the target control parameters include the target opening operation corresponding to the back door and the target control duration corresponding to the target opening operation. In order to ensure the safety of the vehicle and avoid the abuse of the target opening operation in the present application, the target control duration for which the target opening operation can be effective can also be pre-set. When the back door is opened, if there is no abnormality in the vehicle environment, the vehicle can determine whether the current target control parameters are invalid based on the actual control duration and the target control duration of the target user. When the actual control duration is less than the target control duration, it means that the target user can still continue to control the state of the back door. When the actual control duration is greater than or equal to the target control duration, it means that the control process of the target user has ended, and the vehicle determines that the target control parameters have expired. The above process can avoid the vehicle safety risks caused by the continuous opening of the back door when the target user opens the back door.

[0011] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the method also includes: controlling the external camera to collect the video of the external environment while controlling the back door to be closed; judging whether the external environment is abnormal based on the video of the external environment; if the external environment is abnormal, generating a second alarm information based on the external environment; if there is no abnormality in the external environment, if the collection time of the external camera reaches a preset time, controlling the external camera to stop collecting.

[0012] In the above technical solution, when the back door is detected to be closed, the multimedia controller can enable the external camera to collect video of the external environment and monitor the external environment. The above process can ensure that after the back door is closed, the abnormal behavior of the target user is discovered in time to prevent the target user from causing damage to the vehicle. When the external environment is abnormal, the vehicle can generate a second alarm message based on the external environment to facilitate the owner to discover the abnormality outside the vehicle in time. When there is no abnormality in the external environment, the vehicle controls the external camera to stop collecting after a period of time to avoid unnecessary waste of external camera space and vehicle power.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, when the tailgate of the vehicle is closed, the target control parameters of the tailgate are obtained and the target control parameters are sent to the terminal device of the target user, including: when the tailgate is closed, the target control parameters are obtained; when the distance between the target key corresponding to the vehicle and the vehicle is obtained; when the distance is greater than a preset distance, the target control parameters are sent to the terminal device of the target user.

[0014] In combination with the first aspect and the above-mentioned implementation manner, in some possible implementation manners, the method further includes: when the distance is less than or equal to the preset distance, controlling the back door to open.

[0015] In the above technical solution, when the tailgate needs to be opened, the vehicle first determines the distance between the target key of the current vehicle and the vehicle before sending the target control parameters after obtaining them. When the distance is relatively close, it means that the owner is near the vehicle, and the vehicle can directly control the tailgate to open. On the contrary, when the distance is relatively far, it means that the owner is not near the vehicle, and the vehicle can send the target control parameters to the terminal device of the target user. The above process can avoid the inflexibility caused by opening the door through control parameters when the owner is close to the vehicle.

[0016] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the target control parameter includes a target start-up operation, the actual control parameter includes an actual start-up operation, and the response to the actual control parameter executed by the target user determines whether the actual control parameter is consistent with the target control parameter, including: performing feature extraction on the actual start-up operation to obtain a target operation feature; determining the feature similarity between the target operation feature and a preset operation feature corresponding to the target start-up operation; when the feature similarity is less than or equal to the preset similarity, determining that the actual start-up operation is inconsistent with the target start-up operation; when the similarity is greater than the preset similarity, determining that the actual start-up operation is consistent with the target start-up operation.

[0017] In a second aspect, a device for controlling a rear door of a vehicle is provided, the device comprising: a parameter acquisition module, for acquiring target control parameters of the rear door and sending the target control parameters to a terminal device of a target user when the rear door of the vehicle is closed, the target control parameters being used to indicate the actions that the target user needs to perform to open the rear door, and the control duration of the rear door by the target user; a parameter matching module, for determining whether the actual control parameters are consistent with the target control parameters in response to actual control parameters of the target user; and a first control module, for controlling the opening of the rear door when the actual control parameters are consistent with the target control parameters.

[0018] In combination with the second aspect, in some possible implementations, after controlling the opening of the back door, the device also includes: a first monitoring module, used to determine whether the interior environment of the vehicle is abnormal through the interior environment video collected by the interior camera during the opening process of the back door; when the interior environment of the vehicle is abnormal, generate a first alarm message and control the closing of the back door according to the interior environment; when there is no abnormality in the interior environment of the vehicle, determine whether the target control parameter is invalid according to the target control parameter and the actual control parameter.

[0019] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the target control parameter includes a target control duration, and the actual control parameter includes an actual control duration. The first monitoring module is specifically used to: when the actual control duration is less than the target control duration, determine that the target control parameter has not expired; when the actual control duration is greater than or equal to the target control duration, control the back door to close and determine that the target control parameter has expired.

[0020] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes: a second monitoring module, which is used to control the external camera to collect the video of the external environment while controlling the back door to be closed; judge whether the external environment is abnormal based on the external environment video; if the external environment is abnormal, generate a second alarm information based on the external environment; if there is no abnormality in the external environment, if the collection time of the external camera reaches a preset time, control the external camera to stop collecting.

[0021] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the parameter acquisition module is specifically used to: obtain the target control parameter when the tailgate is closed; obtain the distance between the target key corresponding to the vehicle and the vehicle; and send the target control parameter to the terminal device of the target user when the distance is greater than a preset distance.

[0022] In combination with the second aspect and the above-mentioned implementation manner, in some possible implementation manners, the parameter acquisition module is also used to: control the opening of the back door when the distance is less than or equal to the preset distance.

[0023] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the target control parameter includes a target start-up operation, the actual control parameter includes an actual start-up operation, and the parameter matching module is specifically used to: perform feature extraction on the actual start-up operation to obtain a target operation feature; determine the feature similarity between the target operation feature and a preset operation feature corresponding to the target start-up operation; when the feature similarity is less than or equal to the preset similarity, determine that the actual start-up operation is inconsistent with the target start-up operation; when the similarity is greater than the preset similarity, determine that the actual start-up operation is consistent with the target start-up operation.

[0024] In a third aspect, a vehicle is provided, comprising a memory and a processor. The memory is used to store executable program code, and the processor is used to call and run the executable program code from the memory, so that the vehicle executes the method in the first aspect or any possible implementation of the first aspect.

[0025] In a fourth aspect, a computer program product is provided, comprising: a computer program code, which, when executed on a computer, enables the computer to execute the method in the first aspect or any possible implementation of the first aspect.

[0026] In a fifth aspect, a computer-readable storage medium is provided, which stores a computer program code.

[0033] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating 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. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] Before introducing the method of the embodiment of the present application, the application scenario of the embodiment of the present application is first introduced.

[0036] Figure 1 It is a schematic diagram of a scenario for controlling a vehicle tailgate provided in an embodiment of the present application.

[0037] For example, Figure 1 As shown, in order to facilitate users to store and retrieve items during the use of the vehicle, a trunk is usually configured at the rear of the vehicle 101. Correspondingly, the back door 102 serves as the door of the trunk, and can be used by users to store and retrieve items when opened.

[0038] Currently, when users need to open the back door, they can use the following possible methods:

[0039] The first method is to use a physical switch to open the back door 102. When a physical button or a physical key for controlling the back door 102 is configured in the vehicle 101, the user can control the back door 102 to open by rotating the physical button or clicking the physical key.

[0040] The second type is key opening. When the type of the back door 102 in the vehicle 101 is an electric back door, the user can control the back door 102 to open by using a remote control key or a digital key.

[0041] The third type is induction opening. In this mode, the user can control the back door 102 to open by placing his foot under the rear bumper and waving it.

[0042] The fourth type is remote opening. When a vehicle-mounted application is downloaded to the user terminal device, the user can control the opening of the rear door 102 through the rear door control control in the vehicle-mounted application.

[0043] The above-mentioned methods of opening the back door are all for the car owner. It should be understood that the car owner in the embodiment of the present application specifically refers to any user who carries the vehicle key, such as the driver and the driver's corresponding family members. Correspondingly, the non-car owner refers to a user who does not carry the vehicle key.

[0044] When a non-owner user (e.g., a courier) needs to temporarily open the back door to store or retrieve items, the related art mainly requires the owner user to open the back door in the above manner, and then the non-owner user stores or retrieves the items. When the owner user is far away from the vehicle, the above back door opening method brings unnecessary trouble to the owner user, which is not convenient enough and affects the user experience.

[0045] Based on the above problems, an embodiment of the present application provides a method for controlling the tailgate of a vehicle. The method can eliminate the need for the owner to open the tailgate when a non-owner user needs to temporarily open the tailgate, thereby improving the convenience and flexibility of opening the tailgate, saving the owner user unnecessary trouble and improving the user experience.

[0046] Before introducing the method of the embodiment of the present application, the system structure and working principle on which the method of the embodiment of the present application relies during implementation are first introduced.

[0047] Figure 2 It is a structural schematic diagram of a system for controlling a vehicle tailgate provided in an embodiment of the present application.

[0048] For example, Figure 2 As shown, a system 200 for controlling a vehicle tailgate provided in an embodiment of the present application mainly includes: a multimedia controller, a body controller, a tailgate status switch, an audio acquisition device, a vehicle-mounted terminal, a cloud platform, an in-vehicle image acquisition device, an out-of-vehicle image acquisition device, and a terminal device of a vehicle owner.

[0049] When the above system 200 implements the method of the embodiment of the present application, the specific process is as follows:

[0050] When a non-owner user needs to open the back door of the vehicle, the owner user can set the temporary opening operation required by the non-owner user to open the back door based on the owner user's terminal device or based on the vehicle display screen in the vehicle, and send it to the non-owner user's terminal device. Based on this, the multimedia controller can store the current temporary opening operation.

[0051] After the non-car owner user views the temporary start operation on the terminal device, when the temporary start operation is a voice command, the non-car owner user can output the corresponding voice according to the instructions of the voice command. The audio acquisition device (for example, a microphone) is responsible for collecting the voice of the non-car owner user and sending it to the multimedia controller.

[0052] The multimedia controller compares the voice output by the non-owner user with the temporary opening operation to determine whether the non-owner user's identity authentication is successful.

[0053] When the temporary opening operation is a gesture or facial expression, the non-owner user can make corresponding expressions or actions according to the instructions of the gesture or facial expression. The external image acquisition device (for example, an external camera) is responsible for acquiring the facial expression or gesture of the non-owner user and sending it to the multimedia controller.

[0054] The multimedia controller compares the expression or gesture made by the non-owner user with the temporary opening operation to determine whether the non-owner user takes action according to the instruction of the temporary opening operation.

[0055] When the non-owner user's identity authentication is successful, the multimedia controller can send a back door opening operation to the body controller. In response to the back door opening operation, the body controller controls the back door state switch to switch the back door state from closed to open, thereby opening the back door.

[0056] When the back door is successfully opened, the multimedia controller can also send the current status of the back door to the terminal device of the car owner through the vehicle terminal and the cloud platform, so that the car owner can know the changes of the back door status in time.

[0057] Optionally, the vehicle-mounted terminal may be a telematics box (T-box) or a telematics control unit (TCU) in the vehicle.

[0058] After cloud integration, it can serve as a vehicle telematics service provider (TSP).

[0059] In addition, while the back door is open, the multimedia controller can control the in-vehicle image acquisition device (e.g., an in-vehicle camera) to capture images of the in-vehicle environment to determine whether there is any abnormality in the trunk.

[0060] After the back door is closed, the multimedia controller can also control the external image acquisition device to acquire images of the external environment for a period of time to determine whether there is any abnormality outside the vehicle within a short period of time after the back door is closed.

[0061] The specific implementation process of the method in the embodiment of the present application is introduced below.

[0062] Figure 3 is a schematic flow chart of a method for controlling a vehicle back door provided in an embodiment of the present application. It should be understood that the method can be applied to the above Figure 2 The system 200 is specifically applied to Figure 2 In addition, the execution subject of the method is Figure 2 In addition to the multimedia controller in the vehicle, it can be any electronic control unit (Electronic Control Unit, ECU) in the vehicle. In the following description of the embodiments of the present application, the method of the embodiments of the present application is described in detail by taking the multimedia controller as the execution subject of the method.

[0063] For example, Figure 3 As shown, the method 300 includes:

[0064] 301, when the back door of the vehicle is closed, obtain the target control parameters of the back door and send the target control parameters to the terminal device of the target user, where the target control parameters are used to indicate the actions that the target user needs to perform to open the back door and the control time of the back door by the target user.

[0065] It should be understood that the application scenario of the embodiment of the present application is that when the back door of the vehicle is closed, if a non-owner user (i.e., the target user) needs to open the back door of the vehicle, the owner user can pre-set the target control parameters and send them to the terminal device of the target user, so that the target user completes the verification according to the target control parameters. After the verification is successful, the back door can be automatically opened.

[0066] Optionally, different target users may correspond to the same target control parameters or to different target control parameters, which is not limited in the embodiments of the present application.

[0067] The target control parameter is used to indicate the action that the target user needs to perform to open the back door, and the duration for which the target user controls the back door.

[0068] Optionally, the target control parameters include a target opening operation and a target control duration. The target opening operation refers to the action that the target user needs to perform when opening the back door. The target control duration refers to the duration that the target user can control the back door status, specifically, the duration that the target user can control the back door status starting from the moment the target user first opens the back door through the target opening operation.

[0069] Optionally, the type of the target activation operation includes any one of a target activation voice, a target activation gesture, or a target activation expression. The embodiment of the present application does not limit the type of the target activation operation.

[0070] Specifically, when the tailgate of the vehicle is in a closed state, and if the target user has contacted the vehicle owner in advance (i.e., the target user is not an illegal user), if the vehicle owner expects the target user to open the tailgate to store or access items, the vehicle owner can set the target control parameters corresponding to the target user based on the vehicle's on-board display screen or his own terminal device.

[0071] Optionally, the vehicle owner may pre-set the target control parameters before the target user reaches the vicinity of the vehicle, or may set the target control parameters when the target user has reached the vicinity of the vehicle. The embodiment of the present application does not limit the timing of the target user setting the target control parameters.

[0072] For example, the car owner can find the control interface of the back door in the car display or terminal device, and set the target opening operation and target control duration of the current back door based on the control interface of the back door. Regardless of which of the above methods the car owner uses to set the target control parameters, the car display and the terminal device can synchronize and update the target control parameters through the vehicle's T-box and cloud platform. Based on this, the multimedia controller can obtain the target control parameters.

[0073] After obtaining the target control parameters, before sending the target control parameters to the target user's terminal device, the multimedia controller can also determine whether the current owner user is close to the vehicle to determine whether it is necessary to use the target control parameters to enable the target user to open the vehicle's rear door.

[0074] In a possible implementation, when the back door of the vehicle is closed, obtaining a target control parameter of the back door and sending the target control parameter to a terminal device of a target user includes:

[0075] When the back door is closed, the target control parameters are obtained;

[0076] Get the distance between the target key corresponding to the vehicle and the vehicle;

[0077] When the distance is greater than the preset distance, the target control parameter is sent to the terminal device of the target user.

[0078] Optionally, the target key may be a digital key or a remote control key. The digital key may be a Bluetooth Low Energy (BLE) key, a Near Field Communication (NFC) key, or an Ultra Wide Band (UWB) key.

[0079] For example, assuming that the target key is a remote control key, after obtaining the target control parameter, the multimedia controller can control the vehicle communication module to send a radio frequency signal of a certain frequency, that is, a target communication signal. When the remote control key is within the communication range with the vehicle, when the remote control key receives the radio frequency signal, it will send a reply signal to the vehicle.

[0080] Since the communication distance determines the strength of the communication signal, when a reply signal is received through the vehicle communication module, the multimedia controller can further obtain the received signal strength indication (RSSI, also known as "signal strength") of the reply signal, and then determine the distance between the remote control key and the vehicle based on the signal strength.

[0081] When the distance between the vehicle and the remote control key is less than or equal to the preset distance at which the remote control key can communicate, it means that the distance between the vehicle and the remote control key is relatively close. On the contrary, when the distance between the vehicle and the remote control key is greater than the preset distance, it means that the distance between the vehicle and the remote control key is relatively far.

[0082] As another example, assume that the target key is a Bluetooth key based on BLE communication. The multimedia controller can broadcast a beacon signal, i.e., a target communication signal, through the vehicle communication module based on the Bluetooth ranging principle. When the Bluetooth key is near the vehicle, the Bluetooth key can sense the beacon signal and send a reply signal to the vehicle communication module. Similarly, the multimedia controller can obtain the RSSI of the reply signal and determine the distance between the vehicle and the Bluetooth key.

[0083] When the distance between the vehicle and the Bluetooth key is less than or equal to the preset distance at which the Bluetooth key can communicate, it means that the distance between the vehicle and the Bluetooth key is relatively close. On the contrary, when the distance between the vehicle and the Bluetooth key is greater than the preset distance, it means that the distance between the vehicle and the Bluetooth key is relatively far.

[0084] The detection methods for other digital keys are similar and will not be elaborated here.

[0085] When the multimedia controller determines that the distance between the target key and the vehicle is far, it means that the owner is not near the vehicle. In this case, the multimedia controller can send the current target control parameters to the target user's terminal device through the owner's terminal device, or send the current target control parameters to the target user's terminal device through a text message application or a phone application in the vehicle host.

[0086] After receiving the target control parameters through the terminal device of the target user, the target user can perform corresponding actions according to the target start operation in the target control parameters.

[0087] In another scenario, when the distance between the vehicle and the target key is close, it means that the current owner is near the vehicle, and the multimedia controller can directly control the opening of the vehicle's back door.

[0088] In a possible implementation manner, the method further includes:

[0089] When the distance is less than or equal to the preset distance, the back door is controlled to open.

[0090] When the multimedia controller detects that the target key of the vehicle is close to the vehicle, it can directly send a target opening command to the body controller, so that the body controller controls the vehicle's rear door to switch from a closed state to an open state based on the target opening command.

[0091] In the above technical solution, when the tailgate needs to be opened, the vehicle first determines the distance between the target key of the current vehicle and the vehicle before sending the target control parameters after obtaining them. When the distance is relatively close, it means that the owner is near the vehicle, and the vehicle can directly control the tailgate to open. On the contrary, when the distance is relatively far, it means that the owner is not near the vehicle, and the vehicle can send the target control parameters to the terminal device of the target user. The above process can avoid the inflexibility caused by opening the door through control parameters when the owner is close to the vehicle.

[0092] 302 , in response to the actual control parameter of the target user, determining whether the actual control parameter is consistent with the target control parameter.

[0093] After the target user performs a corresponding action according to the target start-up operation, the multimedia controller can obtain the actual control parameters of the target user.

[0094] Optionally, similar to the target control parameter, the actual control parameter includes the actual opening operation of the target user and the actual control duration. The starting time corresponding to the actual control duration is the time when the target user successfully opens the back door for the first time.

[0095] Since the actual control duration is the timing that is triggered when the multimedia controller detects the first successful opening of the back door, the actual control parameter currently obtained by the multimedia controller refers to the actual opening operation. The multimedia controller can compare the target opening operation with the actual opening operation to determine whether the back door can be opened.

[0096] In a possible implementation, the target control parameter includes a target start-up operation, the actual control parameter includes an actual start-up operation, and in response to the actual control parameter executed by the target user, determining whether the actual control parameter is consistent with the target control parameter includes:

[0097] Extract features of the actual opening operation to obtain target operation features;

[0098] Determining a feature similarity between a target operation feature and a preset operation feature corresponding to a target start operation;

[0099] When the feature similarity is less than or equal to the preset similarity, determining that the actual opening operation is inconsistent with the target opening operation;

[0100] When the similarity is greater than the preset similarity, it is determined that the actual opening operation is consistent with the target opening operation.

[0101] For example, when the target start-up operation is a target start-up voice, the multimedia controller can collect the actual start-up voice of the target user through an external microphone. Based on the collected actual start-up voice, the multimedia controller can extract features of the actual start-up voice to obtain target operation features, i.e., target audio features, and then measure the similarity between the target audio features and the preset operation features (i.e., preset audio features) corresponding to the target start-up voice to obtain feature similarity.

[0102] Optionally, similarity measurement methods between audio features include but are not limited to Fourier transform, waveform comparison, Mel spectrum comparison, chroma compression comparison or deep learning method.

[0103] Furthermore, the multimedia controller may compare the current feature similarity with a preset similarity corresponding to the target start-up voice. Optionally, the preset similarity corresponding to the target start-up voice may be 98%.

[0104] When the feature similarity is less than or equal to the preset similarity corresponding to the target start voice, the multimedia controller determines that the actual start operation is consistent with the target start operation. On the contrary, when the feature similarity is greater than the preset similarity corresponding to the target start voice, the multimedia controller determines that the actual start operation is inconsistent with the target start operation.

[0105] In another exemplary embodiment, when the target opening operation is a target opening gesture, the multimedia controller can collect the actual opening gesture of the target user through an external camera. Based on the collected actual opening gesture, the multimedia controller can extract features of the actual opening gesture to obtain target operation features, i.e., target gesture features. The target gesture features include geometric features, shape features, and motion features.

[0106] The geometric features are specifically the number of fingers and the finger positions. The finger positions are the coordinates of the tip of each finger. The shape features refer to the hand contour and the positions of the key points of the hand contour. The motion features refer to the path of the gesture movement.

[0107] The multimedia controller combines the extracted target gesture features to obtain a high-dimensional feature vector, and calculates the similarity between the high-dimensional feature vector and a preset gesture feature vector corresponding to the target opening operation.

[0108] Furthermore, the multimedia controller may compare the current feature similarity with a preset similarity corresponding to the target opening gesture. Optionally, the preset similarity corresponding to the target opening gesture may be 99%.

[0109] When the feature similarity is less than or equal to the preset similarity corresponding to the target start operation, the multimedia controller determines that the actual start operation is consistent with the target start operation. On the contrary, when the feature similarity is greater than the preset similarity corresponding to the target start voice, the multimedia controller determines that the actual start operation is inconsistent with the target start operation.

[0110] In another exemplary embodiment, when the target opening operation is a target opening expression, the multimedia controller can collect the actual opening expression of the target user through an external camera. Based on the collected actual opening expression, the multimedia controller can perform feature extraction on the actual opening expression to obtain a target operation feature, i.e., a target expression feature. The target expression feature includes a geometric feature and a texture feature.

[0111] Among them, geometric features refer to the positions of facial key points and the relative distances and angles between each facial key point.

[0112] The multimedia controller combines the extracted target expression features to obtain a high-dimensional feature vector, and calculates the similarity between the high-dimensional feature vector and a preset expression feature vector corresponding to the target start operation.

[0113] Furthermore, the multimedia controller may compare the current feature similarity with a preset similarity corresponding to the target opening expression. Optionally, the preset similarity corresponding to the target opening expression may be 99%.

[0114] When the feature similarity is less than or equal to the preset similarity corresponding to the target start operation, the multimedia controller determines that the actual start operation is consistent with the target start operation. On the contrary, when the feature similarity is greater than the preset similarity corresponding to the target start voice, the multimedia controller determines that the actual start operation is inconsistent with the target start operation.

[0115] Thus, through the above process, the multimedia controller can determine whether the target user is successfully authenticated.

[0116] 303 , when the actual control parameter is consistent with the target control parameter, the back door is controlled to open.

[0117] When the multimedia controller determines through 302 that the actual opening operation is consistent with the target opening operation, a tailgate opening instruction can be generated and sent to the body controller, so that the body controller responds to the tailgate opening instruction and controls the tailgate status switch to switch the status.

[0118] When the back door of the vehicle is opened, the multimedia controller can time the actual control time of the target user. In order to ensure the safety of the vehicle and the safety of the items in the vehicle after the back door is opened, the multimedia controller can monitor the interior environment of the vehicle through the vehicle's camera.

[0119] In a possible implementation, after controlling the back door to open, the method further includes:

[0120] When the back door is opened, the in-vehicle environment video collected by the in-vehicle camera is used to determine whether the in-vehicle environment is abnormal;

[0121] In the case of an abnormal vehicle interior environment, a first alarm message is generated according to the vehicle interior environment and the back door is controlled to be closed;

[0122] When there is no abnormality in the vehicle environment, determine whether the target control parameter is invalid based on the target control parameter and the actual control parameter.

[0123] When the multimedia controller determines that the back door has been opened, it can control the in-vehicle camera to continuously collect the in-vehicle environment video, and determine whether the in-vehicle environment is abnormal based on the in-vehicle environment video.

[0124] Specifically, after the multimedia controller collects the in-car environment video through the in-car camera, it can identify the action behavior of the target user based on the pre-trained behavior recognition model to determine whether the current target user's behavior is abnormal.

[0125] Specifically, in an embodiment of the present application, technicians collect a large number of annotated video clips, where the annotated content includes normal behavior (for example, the behavior of placing an object) and abnormal behavior (for example, fast movement or violent behavior).

[0126] Based on a large number of annotated video clips, each video clip is divided into short video clips of fixed length. For each short video clip, technicians can use tools such as MediaPipe and OpenPose to detect key points of the human body (for example, wrists, elbows, shoulders, etc.), obtain the coordinates of the positions of these key points, and then record the coordinate changes of the key points of the human body over time through the key points of the human body in multiple consecutive short video clips.

[0127] Furthermore, by taking the coordinates of the key points of the human body corresponding to each time step as the input of the behavior recognition model to form a time series, the output layer of the behavior recognition model is designed as a multi-classifier, and the behavior recognition model is used to predict the behavior category (for example, normal behavior, violent behavior) at future moments.

[0128] Based on the prediction results during the training process and the actual behavior categories at historical moments, the loss function of the behavior recognition model is calculated, and the parameters of the model are continuously adjusted until the behavior recognition model is successfully trained.

[0129] When the behavior recognition model is deployed in the multimedia controller, the multimedia controller can identify the behavior of the target user and determine whether the in-vehicle environment is abnormal based on the in-vehicle environment video captured by the in-vehicle camera as the input parameter of the behavior recognition model.

[0130] When the multimedia controller determines that the in-car environment is abnormal, it can generate a first alarm message based on the in-car environment (i.e., the behavior of the target user) and send the first alarm message to the car owner's terminal device through the TSP and the cloud platform so that the car owner can handle it in time.

[0131] In the above technical solution, when the back door is opened, in order to ensure the safety of the property in the car, the vehicle can monitor the interior environment in real time through the in-car camera, so as to timely detect whether the interior environment is abnormal. When the interior environment is abnormal, the vehicle can generate a first alarm message and immediately close the back door. When the back door is opened, the above abnormal interior environment is detected in a timely and effective manner, and the owner can be informed in time through the alarm, so that the owner can check and deal with it in time.

[0132] When the multimedia controller determines that there is no abnormality in the vehicle environment, it can determine whether the actual control time of the current target user reaches the target control time to determine whether the current target control parameters are valid.

[0133] In a possible implementation, the target control parameter includes a target control duration, and the actual control parameter includes an actual control duration. Determining whether the target control parameter is invalid according to the target control parameter and the actual control parameter includes:

[0134] When the actual control time is less than the target control time, it is determined that the target control parameter is not invalid;

[0135] When the actual control time is greater than or equal to the target control time, the back door is controlled to close and it is determined that the target control parameter has become invalid.

[0136] Based on the above description, it can be known that when the target user controls the back door to open for the first time based on the target opening operation, the multimedia controller takes the current opening time as the starting time and times the control time of the target user, thereby obtaining the actual control time of the target user.

[0137] The multimedia controller can compare the current actual control time with the target control time pre-set by the vehicle owner to determine whether the current actual control time has reached the target control time.

[0138] Optionally, the target control duration is 15 minutes.

[0139] When the actual control duration is less than 15 minutes, it means that the target user's control process has not ended, so the multimedia controller determines that the target control parameters are not invalid. Before the actual control duration reaches the target control duration, the state of the back door is completely controlled by the target user, and the target user can flexibly open the back door based on the target opening operation. In addition, before the control process ends, the target user can also flexibly control the back door to close. In other words, during the period that the target user can control, the back door can be opened or closed repeatedly.

[0140] When the actual control time is greater than or equal to 15 minutes, it means that the control process of the target user has ended and the target user can no longer control the state of the back door. Therefore, the multimedia controller can determine that the target control parameter has failed. Further, when the multimedia controller determines that the target control parameter has failed, it controls the back door to close and completely clears the target control parameter to avoid unnecessary waste of the memory space of the multimedia controller.

[0141] In the above technical solution, the target control parameters include the target opening operation corresponding to the back door and the target control duration corresponding to the target opening operation. In order to ensure the safety of the vehicle and avoid the abuse of the target opening operation in the present application, the target control duration for which the target opening operation can be effective can also be pre-set. When the back door is opened, if there is no abnormality in the vehicle environment, the vehicle can determine whether the current target control parameters are invalid based on the actual control duration and the target control duration of the target user. When the actual control duration is less than the target control duration, it means that the target user can still continue to control the state of the back door. When the actual control duration is greater than or equal to the target control duration, it means that the control process of the target user has ended, and the vehicle determines that the target control parameters have expired. The above process can avoid the vehicle safety risks caused by the continuous opening of the back door when the target user opens the back door.

[0142] When the tailgate is closed, the multimedia controller can also monitor the environment outside the vehicle to prevent the target user from intentionally damaging the vehicle body.

[0143] In a possible implementation manner, the method further includes:

[0144] When the back door is closed, the camera outside the vehicle is controlled to collect video of the environment outside the vehicle;

[0145] Determine whether the external environment is abnormal based on the external environment video;

[0146] In the case of an abnormal environment outside the vehicle, a second alarm message is generated according to the environment outside the vehicle;

[0147] If there is no abnormality in the external environment, if the collection time of the external camera reaches the preset time, the external camera will be controlled to stop collecting.

[0148] When the rear door is detected to be closed, the multimedia controller can control the external camera to collect video of the external environment, and determine whether the target user has abnormal behavior while staying within the vehicle based on the video of the external environment.

[0149] Specifically, the above process of identifying abnormal behavior of the target user is the same as the principle of identifying the target user behavior based on the in-vehicle environment video, and will not be repeated here.

[0150] When the multimedia controller determines that the external environment of the vehicle is abnormal, it generates a second alarm message based on the external environment, and sends the second alarm message to the terminal device of the car owner through the vehicle's T-box and TSP to prompt the car owner to deal with it in time.

[0151] When the multimedia controller determines that there is no abnormality in the external vehicle environment, it determines whether the current acquisition time of the external vehicle camera reaches a preset time.

[0152] Specifically, when the multimedia controller starts to control the external camera to collect data, the external camera collection time can be timed. When the multimedia controller determines that there is no abnormality in the external environment, it determines whether the current collection time reaches the preset time. Optionally, the preset time is 3 minutes.

[0153] When the acquisition time is less than 3 minutes, the multimedia controller continues to control the external camera to collect the video of the external environment and continuously monitors whether the external environment is abnormal. When the acquisition time reaches 3 minutes, the multimedia controller controls the external camera to stop acquisition.

[0154] In the above technical solution, when the back door is detected to be closed, the multimedia controller can enable the external camera to collect video of the external environment and monitor the external environment. The above process can ensure that after the back door is closed, the abnormal behavior of the target user is discovered in time to prevent the target user from causing damage to the vehicle. When the external environment is abnormal, the vehicle can generate a second alarm message based on the external environment to facilitate the owner to discover the abnormality outside the vehicle in time. When there is no abnormality in the external environment, the vehicle controls the external camera to stop collecting after a period of time to avoid unnecessary waste of external camera space and vehicle power.

[0155] In order to facilitate understanding of the implementation process of the embodiment of the present application, Figure 4 The entire scheme of the embodiment of the present application is introduced in detail.

[0158] 401, when the back door of the vehicle is closed, obtain the target control parameters of the back door and send the target control parameters to the terminal device of the target user, where the target control parameters are used to indicate the actions that the target user needs to perform to open the back door and the control time of the back door by the target user.

[0159] 402. Obtain actual control parameters of the target user.

[0160] 403, determine whether the actual control parameter is consistent with the target control parameter.

[0161] When the actual control parameter is inconsistent with the target control parameter, execute 404;

[0162] When the actual control parameter is consistent with the target control parameter, step 405 is executed.

[0163] 404 , when the actual control parameter is inconsistent with the target control parameter, the back door of the vehicle is controlled to continue to close.

[0164] 405 , when the actual control parameter is consistent with the target control parameter, the back door is controlled to open.

[0165] 406 , during the opening process of the tailgate, determine whether the vehicle interior environment is abnormal through the vehicle interior environment video collected by the vehicle interior camera.

[0166] In case of abnormal vehicle environment, return to 404;

[0167] If there is no abnormality in the vehicle environment, execute 407.

[0168] 407 , when there is no abnormality in the vehicle environment, determine whether the actual control time reaches the target control time.

[0169] When the actual control time is less than the target control time, execute 408;

[0170] When the actual control time is greater than or equal to the target control time, 409 is executed.

[0171] 408. When the actual control duration is less than the target control duration, it is determined that the target control parameter is not invalid.

[0172] 409, when the actual control time is greater than or equal to the target control time, the back door is controlled to close and it is determined that the target control parameter has become invalid.

[0173] 401-409 in the above method 400 and 301-303 in method 300 have the same inventive concept. Please refer to the introduction in method 300 for details, which will not be repeated here.

[0174] In summary, when the back door of the vehicle is closed, the present application proposes a method for controlling the back door of the vehicle. In the specific implementation process of the method, when the back door of the vehicle is closed, the vehicle can obtain the target control parameter of the current back door and send it to the terminal device of the target user. Further, the vehicle determines whether the actual control parameter is consistent with the target control parameter by receiving the actual control parameter executed by the target user based on the target control parameter. When the actual control parameter is consistent with the target control parameter, the back door of the vehicle is controlled to open. When the actual control parameter is inconsistent with the target control parameter, the back door of the vehicle is controlled to close. In the above process of opening the back door, the owner user does not need to control the back door to open by using a key or a back door switch. Therefore, when the back door needs to be opened, even if the owner user is not near the vehicle, the vehicle can also open the back door by parameter matching when the parameter matching is detected to be successful, which not only improves the flexibility and convenience of opening the back door, but also takes into account the safety of opening the back door, reduces unnecessary troubles for the owner user, and improves the user experience.

[0176] For example, Figure 5 As shown, the device 500 includes:

[0177] The parameter acquisition module 501 is used to acquire the target control parameter of the back door when the back door of the vehicle is closed and send the target control parameter to the terminal device of the target user, wherein the target control parameter is used to indicate the action that the target user needs to perform to open the back door and the control time of the back door by the target user;

[0185] In one possible implementation, the parameter acquisition module 501 is specifically used to: when the tailgate is closed, obtain the distance between the target key corresponding to the vehicle and the vehicle; when the distance is greater than a preset distance, obtain the target control parameter and send the target control parameter to the terminal device of the target user.
