[0039] It should be understood that the specific embodiments described herein are only used to explain the application, and are not used to limit the application.

[0040] Referring to Figure 1 , Figure 1 Fig. 1 is a flowchart of a first embodiment of a vehicle terminal interaction method according to the present application.

[0041] The embodiments of the vehicle terminal interaction method according to the present application are provided. It should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described herein can be performed in a sequence different from that shown herein. In the present embodiment, the vehicle terminal interaction method is applied to a vehicle terminal. In the present embodiment, the vehicle terminal interaction method comprises the following steps.

[0042] In step S10, GPS positioning is performed by a first GPS module in the vehicle in which the vehicle terminal is located and a second GPS module in the target user equipment, to obtain a first distance between the target user equipment and the vehicle.

[0043] A GPS module (hereinafter referred to as a first GPS module for the sake of distinction), a Bluetooth module (hereinafter referred to as a first Bluetooth module for the sake of distinction), and a UWB (Ultra Wide Band) module (hereinafter referred to as a first UWB module for the sake of distinction) are provided in the vehicle in which the vehicle terminal is located. The number and the setting position of the first GPS module, the first Bluetooth module, and the first UWB module in the vehicle are not limited in the present embodiment. The user equipment can be a user's mobile phone, earphone, smart watch, or the like, which is not limited in the present embodiment. Hereinafter, the user equipment that interacts with the vehicle terminal is referred to as a target user equipment for the sake of distinction. A GPS module (hereinafter referred to as a second GPS module for the sake of distinction), a Bluetooth module (hereinafter referred to as a second Bluetooth module for the sake of distinction), and a UWB module (hereinafter referred to as a second UWB module for the sake of distinction) are provided in the target user equipment. In an available implementation, the first Bluetooth module and the second Bluetooth module can be low-power Bluetooth modules.

[0044] In the case where the vehicle terminal needs to position the location of the target user equipment, and then trigger a directional event based on the location of the target user equipment, the first GPS module in the vehicle terminal can be turned on first, and the second GPS module in the target user equipment can be turned on first. GPS positioning is performed by the first GPS module and the second GPS module, to obtain the distance between the target user equipment and the vehicle (hereinafter referred to as a first distance for the sake of distinction).

[0045] In step S20, if the first distance is less than a first threshold value and greater than or equal to a second threshold value, Bluetooth positioning is performed by the first Bluetooth module in the vehicle and the second Bluetooth module in the target user equipment, to obtain a second distance between the target user equipment and the vehicle, wherein the first threshold value is greater than the second threshold value.

[0046] The first threshold value and the second threshold value can be set in advance as required, and the first threshold value is set to be greater than the second threshold value. The vehicle terminal or the target user equipment can compare the first distance with the first threshold value and the second threshold value. If the first distance is less than the first threshold value and greater than or equal to the second threshold value, and the first Bluetooth module is not started at this time, the first Bluetooth module can be started, and then Bluetooth positioning is performed with the second Bluetooth module of the target user equipment. If the first distance is less than the first threshold value and greater than or equal to the second threshold value, and the second Bluetooth module is not started at this time, the second Bluetooth module can be started, and then Bluetooth positioning is performed with the first Bluetooth module.

[0047] The Bluetooth positioning performed by the first Bluetooth module and the second Bluetooth module can obtain a distance (hereinafter referred to as a second distance for distinction) between the target user equipment and the vehicle.

[0048] In an implementation, before the Bluetooth positioning performed by the first Bluetooth module and the second Bluetooth module, the vehicle terminal can verify the identity of the user (the owner or the passenger) based on asymmetric encryption, and after the verification is passed, the Bluetooth positioning is performed based on the first Bluetooth module and the second module to obtain the second distance.

[0049] In step S30, if the first distance is less than the second threshold value, or if the second distance is less than the second threshold value, UWB positioning is performed by a first ultra-wideband (UWB) module in the vehicle and a second UWB module in the target user equipment to obtain target position information of the target user equipment relative to the vehicle.

[0050] If the first distance is less than the second threshold value, or if the second distance is less than the second threshold value after the second distance is obtained by positioning, and the first UWB module is not started at this time, the first UWB module can be started, and then UWB positioning is performed with the second UWB module of the target user equipment. If the first distance is less than the second threshold value, or if the second distance is less than the second threshold value after the second distance is obtained by positioning, and the second UWB module is not started at this time, the second UWB module can be started, and then UWB positioning is performed with the first UWB module of the vehicle.

[0051] The UWB positioning performed by the first UWB module and the second UWB module can obtain position information of the target user equipment relative to the vehicle (hereinafter referred to as target position information for distinction). The target position information can be information representing the position of the target user equipment relative to the vehicle, and the data form thereof can be pre-set as needed, for example, can include the distance and / or angle of the target user equipment relative to the vehicle. The target user equipment relative to the vehicle can specifically refer to one or more reference points in the target user equipment relative to one or more reference points in the vehicle. The reference points can be pre-selected as needed, and the reference points can be selected according to the principle of the UWB positioning algorithm, which is not limited here.

[0052] In the specific embodiment, the number and position of the reference points in the target user equipment and the vehicle can be determined according to the number and position of the UWB modules arranged in the target user equipment and the vehicle. The more the number of the reference points in the target user equipment and the vehicle, or the more dispersed the positions of the reference points, the higher the discrimination of the target position information, that is, the position and attitude of the target user equipment change slightly, which will cause the change of the target position information obtained by positioning, thereby avoiding the false triggering probability of the target directional event. However, the more the number of the reference points in the target user equipment and the vehicle, or the more dispersed the positions of the reference points, the more the number of the UWB modules arranged in the target user equipment and the vehicle, and the more dispersed the positions of the UWB modules, thereby the cost is higher. Therefore, in the specific embodiment, appropriate settings can be made according to specific circumstances.

[0053] In step S40, a target directional event is triggered based on the target position information, and an interaction operation corresponding to the target directional event is performed.

[0054] After obtaining the target position information, the vehicle-mounted terminal can trigger a target directional event when the target position information meets a certain condition pre-set, and perform an interaction operation corresponding to the target directional event. The pre-set condition can be set as needed, which is not limited here.

[0055] In this embodiment, the vehicle-mounted terminal triggers a directional event when the target position information meets a certain condition, and the vehicle-mounted terminal can perform a corresponding interaction operation based on the triggered directional event, thereby achieving the effect that the user can trigger the vehicle-mounted terminal to perform a certain operation when the user equipment is placed at a certain position.

[0056] In an implementation, the condition for triggering the target directional event based on the target position information can be that the target position information matches preset position information. The preset position information can be position information set in advance as needed, representing a position range in which the user needs to place the user device, and the setting of the preset position information is not limited herein. For example, in an implementation, the preset position information can be customized by the user in the vehicle terminal. The vehicle terminal can match the target position information with the preset position information, and if it is detected that the two match, a directional event (hereinafter referred to as a target directional event for distinction) is triggered. Depending on the data form of the target position information and the preset position information, the specific manner of information matching is different, and the corresponding determination criteria for the two information to match are also different, which can be set as needed. For example, the preset position information can include an angle range and a distance range, and the target position information includes an angle and a distance of a reference point in the target user device relative to a reference point in the vehicle. When matching, it is determined whether the angle in the target position information falls within the angle range in the preset position information, and whether the distance in the target position information falls within the distance range in the preset position information. If both fall within, it is determined that the two information match.

[0057] In an implementation, there can be multiple preset position information, and the target directional event can be triggered when it is detected that the target position information matches one of the preset position information.

[0058] Some or certain operations that the vehicle terminal can perform can be set as operations corresponding to the directional event as needed in advance, which are referred to as interactive operations for distinction because they are performed based on the triggered target directional event. The specific operation of the interactive operation is not limited herein, and in some implementations, the interactive operation corresponding to the directional event can also be set to be customizable by the user. In some implementations, different interactive operations can be set for directional events triggered by different user devices, and / or different interactive operations can be set for directional events triggered by different preset position information. Among them, the directional event triggered by a certain user device refers to a directional event triggered based on the matching of the position information of the user device relative to the vehicle terminal with the preset position information; the directional event triggered by a certain preset position information refers to a directional event triggered based on the matching of the position information of the user device relative to the vehicle terminal with the preset position information.

[0059] In an implementation, the preset position information can be preset according to the position of a controllable component in the vehicle relative to a preset reference point in the vehicle, that is, the preset position information represents the position information of a region within a certain range around the controllable component relative to the preset reference point, and each controllable component in the vehicle corresponds to a preset position information; the preset interaction operation corresponding to the target directional event can be: the vehicle terminal controls the controllable component to switch to another state different from the current state according to the current state of the controllable component corresponding to the preset position information matched with the target position information; for example, when the controllable component is a window, if the window is currently in an open state, the window is closed, and if the window is currently in a closed state, the window is opened; for another example, when the controllable component is a seat with adjustable posture and the seat has n postures, the seat can be adjusted from a current posture i to a next posture i+1, and the order between the postures can be preset as needed. That is, compared with the current manual control of the state of the controllable component in the vehicle terminal, in the implementation, the user can control the state switching of the controllable component by placing the user device at a position within a certain range around the controllable component.

[0060] In an implementation, the hardware device carrying the vehicle terminal can be set in a rotatable form, that is, the rotation thereof can be controlled to change the orientation; in addition to performing the preset interaction operation corresponding to the target directional event, the vehicle terminal can also control the hardware device to change the direction to face the direction where the target user device is located after triggering the target directional event, thereby increasing the interactivity with the user and making the interaction between the user and the vehicle terminal more natural.

[0061] It should be noted that in the embodiment, the target position information of the target user device relative to the vehicle is obtained through UWB positioning by the first UWB module in the vehicle where the vehicle terminal is located and the second UWB module in the target user device, the target directional event is triggered based on the target position information, the preset interaction operation corresponding to the target directional event is performed, the effect that the user can trigger the vehicle terminal to perform a certain operation when placing the user device at a certain position is achieved, and a vehicle terminal interaction mode based on UWB technology is provided, thereby providing a more abundant interaction mode for the user.

[0062] And, in the embodiment, in the case that the target position information of the target user equipment relative to the vehicle is needed to be obtained based on the UWB module to trigger the target directional event according to the target position information, the vehicle terminal and the target user equipment can both start the GPS module first, and in the case that the distance between the target user equipment and the vehicle obtained based on the GPS module is less than the first threshold and greater than or equal to the second threshold, the Bluetooth module is started to perform positioning, and in the case that the distance between the target user equipment and the vehicle obtained based on the Bluetooth module is less than the second threshold or the distance between the target user equipment and the vehicle obtained based on the GPS module is less than the second threshold, the UWB module is started to perform positioning, so that the gradual approaching detection from large range and low precision to small range and high precision is realized, the software and hardware resources can be saved, and the detection precision is improved.

[0063] Based on the above first embodiment, the second embodiment of the vehicle terminal interaction method of the application is proposed, in which the step S10 comprises:

[0064] In step S101, the first GPS module in the vehicle where the vehicle terminal is located is used to perform GPS positioning to obtain a first position.

[0065] The vehicle terminal can call the first GPS module to perform GPS positioning to obtain the position of the vehicle (hereinafter referred to as the first position for distinction).

[0066] In step S102, the second position of the target user equipment sent by the server is received, which is obtained by the target user equipment through the second GPS module and uploaded to the server.

[0067] The target user equipment can perform GPS positioning through the second GPS module to obtain the position of the target user equipment (hereinafter referred to as the second position for distinction). The target user equipment can upload the second position to the server, and the server sends the second position to the vehicle terminal.

[0068] In step S103, the first distance between the target user equipment and the vehicle is calculated according to the first position and the second position.

[0069] The vehicle terminal can calculate the first distance between the target user equipment and the vehicle according to the first position and the second position.

[0070] In an implementable embodiment, the first position can be uploaded to the server by the vehicle terminal, and the second position can be uploaded to the server by the target user equipment. The server can calculate the first distance according to the first position and the second position.

[0071] In an implementable embodiment, the step S102 comprises:

[0072] The vehicle terminal sends the vehicle identity information of the vehicle to the server, so that the server searches for the target equipment identity information of the target user equipment bound with the vehicle identity information, and establishes communication with the target user equipment according to the target equipment identity information to obtain the second position sent by the target user equipment.

[0073] The vehicle identity information of the vehicle can include information for distinguishing the vehicle from other vehicles, such as the license plate number of the vehicle. The equipment identity information of the target user equipment is referred to as the target equipment identity information for distinction. The target equipment identity information can include information for distinguishing the target user equipment from other user equipment, such as the UWB address of the equipment, the equipment serial number, etc.

[0074] The server can pre-store the equipment identity information of the user equipment of each user, the vehicle identity information of the vehicle of each user, and the binding relationship between the equipment identity information and the vehicle identity information.

[0075] The vehicle terminal can send the vehicle identity information of the vehicle to the server. After receiving the vehicle identity information, the server can search for the target equipment identity information of the target user equipment bound with the vehicle identity information, and establish communication with the target user equipment according to the target equipment identity information, so as to obtain the second position sent by the target user equipment.

[0076] The vehicle terminal receives the second position sent by the server.

[0077] In an implementable embodiment, the target equipment identity information can be sent to the server by the target user equipment. The server can search for the vehicle identity information bound with the target equipment identity information, and establish communication with the vehicle terminal based on the vehicle identity information to obtain the first position sent by the vehicle terminal, or forward the second position sent by the target user equipment to the vehicle terminal.

[0078] Based on the first / second embodiment, a third embodiment of the vehicle terminal interaction method of the present application is provided. In the present embodiment, before the step S20, the method further comprises:

[0079] In step S50, if the first distance is less than the first threshold value and greater than or equal to the second threshold value, the target device identity information sent by the target user equipment is acquired through communication between the first Bluetooth module and the second Bluetooth module.

[0080] If the first distance is less than the first threshold value and greater than or equal to the second threshold value, the vehicle-mounted terminal can first start the first Bluetooth module, communicate with the second Bluetooth module in the target user equipment, acquire the target device identity information sent by the target user equipment, verify the device identity information, and then perform positioning through the first Bluetooth module and the second Bluetooth module to obtain the second distance after verification.

[0081] In step S60, the target device identity information is matched with preset device identity information.

[0082] In an available implementation, the vehicle-mounted terminal can verify the target device identity information by matching the target device identity information with preset device identity information. The preset device identity information can be the identity information of the user equipment of the user of the vehicle that is acquired by the vehicle-mounted terminal in advance, and the acquisition manner is not limited herein. For example, the user (the owner or the passenger) of the vehicle can input the device identity information of the user equipment into the vehicle-mounted terminal before riding the vehicle.

[0083] In step S70, if the target device identity information matches the preset device identity information, the step S20 is executed.

[0084] If the vehicle-mounted terminal matches the target device identity information with the preset device identity information, the target user equipment and the vehicle can be positioned through the first Bluetooth module and the second Bluetooth module to obtain the second distance.

[0085] In an available implementation, before the step S60, the method further includes:

[0086] In step S80, the device identity information bound with the vehicle identity information of the vehicle is acquired from a server as the preset device identity information, wherein the server receives and binds the target device identity information and the vehicle identity information sent by the client deployed in the target user equipment.

[0087] The server can store the vehicle identity information of each vehicle and the device identity information of the user equipment bound with the vehicle identity information of each vehicle. The vehicle-mounted terminal can acquire the device identity information bound with the vehicle identity information of the vehicle from the server as the preset device identity information.

[0088] In a feasible implementation, the vehicle identity information stored in the server and the device identity information and the binding relationship therebetween can be uploaded to the server by the user through the client deployed in the user device, that is, in the client, the user can register the binding relationship between the vehicle identity information and the device identity information, the vehicle identity information can be entered by the user in the client, the device identity information can be acquired by the client through dispatching the information interface provided in the user device, the client uploads the acquired vehicle identity information and device identity information to the server, the server binds the two information, and can send the information to the vehicle terminal.

[0089] Based on the first, second and / or third embodiments, a fourth embodiment of the vehicle terminal interaction method of the application is proposed. In the embodiment, the step of performing the preset interaction operation corresponding to the target directional event in step S40 comprises:

[0090] In step S401, after triggering the target directional event, a monitoring operation on the user voice instruction is performed.

[0091] In step S402, if the user voice instruction is monitored, the user voice instruction is responded to.

[0092] The preset interaction operation corresponding to the target directional event can be that the vehicle terminal starts monitoring the user voice instruction, and responds to the user voice instruction after monitoring the user voice instruction. That is, compared with the current wake-up mode of the voice control function of the vehicle terminal based on the wake-up word, in the embodiment, the user can wake up the voice control function of the vehicle terminal by placing the user device in a certain position, and then control the vehicle terminal to perform corresponding operations through voice.

[0093] In the embodiment, the specific implementation of the monitoring operation of monitoring the user voice instruction is not limited. For example, in a feasible implementation, monitoring the user voice instruction can be through a microphone in the vehicle to record a sound signal, and identifying the sound signal to determine whether there is a user voice instruction. For another example, in a feasible implementation, monitoring the user voice instruction can be monitoring whether a user voice instruction sent by a target user device triggering the target directional event is received, and the target user device can record a sound signal through a microphone after the vehicle terminal triggers the target directional event, identify the sound signal to determine whether there is a user voice instruction, and send the user voice instruction to the vehicle terminal after determining that there is a user voice instruction.

[0094] In an implementation, the control authority of each user type can be set in advance, and the control authorities of different user types can be different. The control authority can include the objects that can be controlled by the user of the user type and the priority of the control on the objects. For example, the control objects in the control authority of the main driver can include all the windows, but the control objects in the control authority of the co-driver can include only the windows at the co-driver position, and the priority of the control on the windows in the control authority of the main driver is the highest, and the priority of the control on the windows at the co-driver position in the control authority of the co-driver is lower than that of the main driver. This does not limit the way of obtaining the control authority of each user type in the vehicle terminal. For example, in an implementation, the user can set the control authority of each user type in the vehicle terminal, and the vehicle terminal stores the set control authority and obtains the control authority when it is needed. The preset control authority corresponding to the target user type is referred to as the target control authority, and the user type of the user of the target user device is referred to as the target user type. After the vehicle terminal monitors the user voice instruction, it can detect whether the user voice instruction conforms to the target control authority. The vehicle terminal responds to the user voice instruction after detecting that the user voice instruction conforms to the target control authority. For example, the user voice instruction is to close the window of the co-driver, and then the vehicle terminal can respond to the instruction to close the window of the co-driver. For another example, the user voice instruction is to switch songs, and then the vehicle terminal can respond to the instruction to switch songs. In an implementation, the vehicle terminal can output a prompt information to prompt the user that the user has no authority when it detects that the user voice instruction does not conform to the target control authority. The way of outputting the prompt information can be voice output or output through the display screen, which is not limited herein.

[0095] In an implementation, if the user type of the user of the target user device is the vehicle owner, the vehicle terminal can receive the authority data sent by the target user device, wherein the authority data includes the control authority corresponding to each user type, and the authority data is set by the vehicle owner in the client deployed on the target user device. The vehicle owner can set the authority data in the client deployed on the user device, and the authority data includes the control authority corresponding to each user type. When the user device of the vehicle owner interacts with the vehicle terminal, for example, after the second UWB module in the user device of the vehicle owner establishes communication with the first UWB module in the vehicle, the authority data can be synchronized to the vehicle terminal based on the communication channel. In an implementation, the vehicle terminal can determine whether the user corresponding to the target user device is seated at the main driver position based on the target position information, and after determining that the user of the target user device is seated at the main driver position, the first UWB module and the second UWB module can be converted from the positioning mode to the data transmission mode, and then the authority data is synchronized from the target user device.

[0096] In an implementation, if there are multiple target directional events triggered by multiple target user devices within a preset time interval, the vehicle terminal can determine a privileged device from the multiple target user devices.

[0097] The preset time interval can be set in advance as needed, and can be set to be relatively short. If there are multiple target directional events triggered by multiple target user devices within a preset time interval, it indicates that multiple users use their user devices to interact with the vehicle terminal within a very short time interval. In this case, the vehicle terminal can determine a user device (hereinafter referred to as a privileged device for distinction) from the multiple target user devices. There are many ways to determine the privileged device, that is, there are many ways to determine which target user device is the privileged device, which are not limited herein. For example, in an implementation, the priority of each user device set in advance can be used to determine, and for example, prompt information can be output to remind the user to confirm which device has the triggering privilege, and the confirmation result of the user feedback is received, and the privileged device is determined based on the confirmation result; the way of outputting the prompt information and receiving the confirmation result of the user feedback is not limited, for example, the prompt can be output through voice, and the confirmation result of the user feedback through voice instruction is received.

[0098] It should be noted that the preset interaction operation corresponding to the target directional event triggered by different user devices can be different. For example, in an implementation, the vehicle terminal can start monitoring user voice instructions based on the target directional event triggered by the privileged device; if a user voice instruction is monitored, it is detected whether the user voice instruction conforms to a target control privilege, wherein the target control privilege is a control privilege set in advance for a user type corresponding to the privileged device; if the user voice instruction conforms to the target control privilege, the user voice instruction is responded.

[0099] In the present embodiment, in the case where multiple users use their user devices to interact with the vehicle terminal within a very short time interval, the privileged device is determined from the multiple target user devices triggering the target directional events, and the preset interaction operation corresponding to the target directional event triggered by the privileged device is performed, thereby avoiding the situation that the control instructions of multiple users conflict and cause the vehicle terminal to respond incorrectly.

[0100] In an implementation, if the hardware device carrying the vehicle terminal can be set in a rotatable form, the vehicle terminal can control the hardware device to change direction to face the direction where the privileged device is located after determining the privileged device.

[0101] In a possible implementation, if the target position information matches the preset position information, a first direction of a preset reference point in the vehicle relative to the target user device is determined according to the target position information, and whether the first direction is consistent with a second direction is detected, where the second direction is a posture pointing direction of the target user device, and the posture pointing direction is detected by a posture detection apparatus in the target user device. If the first direction is consistent with the second direction, a target pointing event is triggered.

[0102] The target position information indicates a position of the target user device relative to the vehicle, and thus a direction of a preset reference point in the vehicle relative to the target user device (hereinafter referred to as a first direction for the sake of distinction) can be determined according to the target position information. The preset reference point can be selected as needed, which is not limited herein. A posture detection apparatus is arranged in the target user device, and can detect a posture pointing direction (hereinafter referred to as a second direction for the sake of distinction) of the target user device. In this embodiment, a specific implementation of the posture detection apparatus is not limited, for example, an IMU (Inertial Measurement Unit) can be used to implement the posture detection apparatus. The first direction and the second direction can be converted into the same coordinate system for comparison, and if the two directions differ by an angle within a preset range in the same coordinate system, it can be determined that the first direction is consistent with the second direction.

[0103] The first direction being consistent with the second direction means that the user adjusts the posture of the user device to be "pointed" to the position of the preset reference point in the vehicle. In the case that the target position information matches the preset position information and the first direction is consistent with the second direction, the vehicle terminal can trigger a target pointing event. That is, the target pointing event can be triggered when the user places the user device to a certain position and adjusts the posture of the user device to be "pointed" to the position of the preset reference point in the vehicle, so that the vehicle terminal can perform a corresponding interactive operation.

[0104] Since the posture pointing direction of the user device is added, the situation that the user mistakenly triggers the interactive operation of the vehicle terminal when using the user device in the vehicle can be further avoided.

[0105] Based on the first, second, third and / or fourth embodiments, a fifth embodiment of the vehicle terminal interactive method of the present application is provided. In a possible implementation, the step of triggering a target pointing event based on the target position information in step S40 includes:

[0106] In step S403, a target user type is obtained, where the target user type is a user type to which a user of the target user device belongs.

[0107] Step S404, if the target position information matches the preset position information, triggering the target directional event, wherein the preset position information is the position information corresponding to the target user type in the preset position information.

[0108] The type of the user can be divided into the main driver, the co-driver and the rear passenger, and the positions of the users of different types in the vehicle are different. In this embodiment, different position information (hereinafter referred to as event triggering judgment position information for the sake of distinction) can be set for different user types in advance, for example, the position range represented by the event triggering judgment position information can fall within the activity range of the user of the type in the vehicle, but can avoid the position range where the user device of the user of the type is placed when the user device is used in the vehicle.

[0109] In this embodiment, the type of the user of the target user device is referred to as the target user type for the sake of distinction.

[0110] There are many ways to obtain the target user type, which are not limited herein. For example, in an available implementation, type judgment position information corresponding to different user types can be set in advance, the type judgment position information can represent the activity range of the user of the type in the vehicle, and it can be detected whether the position represented by the target position information falls within the activity range represented by the type judgment position information corresponding to each user type. If the position falls within the activity range represented by the type judgment position information corresponding to one user type, the user type is taken as the target user type.

[0111] After the target user type is determined, the vehicle-mounted terminal can select the position information corresponding to the target user type from the preset position information (i.e., each event triggering judgment position information) as the preset position information, and then match the preset position information with the target position information.

[0112] In an available implementation, the step S403 includes:

[0113] Step S4031, obtaining the target device identity information of the target user device, obtaining the target user identity information bound with the target device identity information from the local or the server, determining the target user type according to the target user identity information, wherein the server receives and binds the target device identity information and the target user identity information sent by the client deployed in the target user device, or sends the target device identity information and the target user identity information to the vehicle-mounted terminal after binding.

[0114] The device identity information of the target user device is referred to as target device identity information for the sake of distinction. The target device identity information can include information for distinguishing the target user device from other user devices, such as the UWB address of the device, the device serial number, etc. The user identity information bound to the target device identity information is referred to as target user identity information for the sake of distinction. The target user identity information can include the user type, or can also include other information related to the user identity, which is not limited herein.

[0115] There are many ways for the vehicle terminal to obtain the target device identity information, which is not limited herein. For example, the target device identity information sent by the target user device can be received through communication between the first UWB module and the second UWB module.

[0116] In an implementable embodiment, the vehicle terminal can locally store the device identity information of each user device and the user identity information bound to the device identity information, so that when the target device identity information is obtained, the target user identity information bound to the target device identity information can be obtained locally. The stored information can be entered by the user locally on the vehicle terminal, or can also be obtained by the vehicle terminal from the server, and the specific manner is not limited herein.

[0117] In an implementable embodiment, the server can store the device identity information of each user device and the user identity information bound to the device identity information, so that when the vehicle terminal obtains the target device identity information, the target user identity information bound to the target device identity information can be obtained from the server.

[0118] In an implementable embodiment, the device identity information and the user identity information stored in the server and the binding relationship therebetween can be uploaded to the server by the user through the client deployed in the user device, that is, in the client, the user can register the binding relationship between the device identity information and the user identity information. The user identity information can be entered by the user in the client, and the device identity information can be obtained by the client through scheduling the information interface provided in the user device. The client uploads the obtained user identity information and device identity information to the server, the server binds the two information, and can send the information to the vehicle terminal.

[0119] In an implementable embodiment, the step S403 includes:

[0120] In step S4031, the user type sent by the target user device is received and used as the target user type.

[0121] The vehicle terminal can also directly receive a user type sent by the target user equipment. The user type sent by the target user equipment can be input by a user in the target user equipment. The vehicle terminal receives the user type sent by the target user equipment can be based on communication between the first UWB module and the second UWB module, or can be received based on other communication manners, which is not limited herein.
