Description

Technical Field

[0001] This application relates to the technical field of intelligent vehicles, and in particular, to a vehicle operation method, an information processing method, a communication device, and a system. Background Art

[0002] With the development of vehicle intelligence, the technology of car keys has been gradually upgraded, providing people with a more convenient and user-friendly vehicle usage experience. The latest generation of digital key technology integrates the advantages of different communication technologies such as Near Field Communication (NFC), Bluetooth Low Energy (BLE), and Ultra Wide Band (UWB), achieving a better balance in terms of power consumption, security, and accuracy.

[0003] Generally, digital key technology can determine the spatial distance between the digital key and the vehicle based on the Received Signal Strength Indication (RSSI) of Bluetooth or the Time Of Flight (TOF) of Ultra Wide Band, and distinguish different functional areas according to different spatial distance thresholds, such as the vehicle welcome area and the unlocking area. When the spatial distance between the digital key and the vehicle is less than or equal to the distance threshold corresponding to the functional area, the vehicle performs the operation corresponding to the functional area.

[0004] However, in the above method, when the distance threshold corresponding to the functional area is set unreasonably, the timing of the vehicle performing the operation corresponding to the functional area does not match the expectation. Summary of the Invention

[0005] Embodiments of this application provide a vehicle operation method, an information processing method, a communication device, and a system, which can ensure that the timing of the vehicle performing the corresponding operation matches the expectation, and avoid the vehicle performing the corresponding operation too early or too late.

[0006] In a first aspect, embodiments of this application provide a vehicle operation method, which is applied to a first communication device. It can be understood that this method can be executed by the first communication device, or can be a chip (system) or circuit for the first communication device, and this application does not make any limitations in this regard. The method includes:

[0007] Determine a first distance threshold based on the motion state of the client, where the motion state of the client corresponds to the motion speed of the client; when the spatial distance between the client and the vehicle end is less than or equal to the first distance threshold, determine to perform a first operation.

[0008] In the embodiments of the present application, the client is the client corresponding to the digital key. When the client is in different motion states, the motion speed of the client is different. When the spatial distance between the client and the vehicle end is the same, due to different motion states of the client, the remaining time from the client to the vehicle end is different. Therefore, the first communication device can determine a more reasonable first distance threshold based on the motion state of the client, taking into account the remaining time from the client to the vehicle end, ensuring that the timing of the vehicle executing the first operation matches the expectation, and avoiding the vehicle executing the first operation too early or too late, thereby better controlling the timing of the vehicle end function response.

[0009] In combination with the first aspect, in a possible implementation manner, the determining the first distance threshold based on the motion state of the client includes:

[0010] Obtaining a coefficient corresponding to the motion state of the client; determining the first distance threshold based on the coefficient and a second distance threshold, where the second distance threshold is the distance threshold corresponding to the first operation when the client is in a reference motion state.

[0011] In the embodiments of the present application, the reference motion state may be a pre-set motion state, and the second distance threshold is the distance threshold corresponding to the first operation when the client is in the reference motion state. The first communication device stores the second distance threshold. The first communication device can adjust the first distance threshold corresponding to the first operation in the current motion state of the client based on the coefficient on the basis of the second distance threshold, so that the first distance threshold can be adapted to the current motion state of the client.

[0012] In combination with the first aspect, in a possible implementation manner, the first distance threshold is the product of the coefficient and the second distance threshold.

[0013] In combination with the first aspect, in a possible implementation manner, the coefficient is positively correlated with the motion speed corresponding to the motion state of the client.

[0014] In the embodiments of the present application, the greater the motion speed corresponding to the motion state of the client, the greater the coefficient corresponding to the motion state of the client, and the greater the first distance threshold, which can keep the remaining time from the client to the vehicle end unchanged, ensure that the timing of the vehicle executing the first operation matches the expectation, and avoid the vehicle executing the first operation too early or too late.

[0015] In combination with the first aspect, in a possible implementation manner, the motion state of the client is determined by the speed information of the client on multiple coordinate axes.

[0016] In the embodiments of the present application, the coordinate system where the multiple coordinate axes are located can be determined based on the plane where the screen of the client is located. The directions corresponding to the multiple coordinate axes are different, and the speed information of the client on one coordinate axis is the speed information of the client in the direction corresponding to the coordinate axis. It can be understood that by combining the speed information of the client in each direction, the precise motion state of the client can be obtained.

[0017] Combined with the first aspect, in a possible implementation manner, the speed information includes the acceleration and angular velocity of the client on the multiple coordinate axes.

[0018] In the embodiments of the present application, based on the acceleration and angular velocity of the client on the multiple coordinate axes, the motion state of the client can be made more precise.

[0019] Combined with the first aspect, in a possible implementation manner, the multiple coordinate axes include a first coordinate axis, a second coordinate axis, and a third coordinate axis. The first coordinate axis and the second coordinate axis are parallel to the plane where the screen of the client is located, and the third coordinate axis is perpendicular to the plane where the screen of the client is located.

[0020] In the embodiments of the present application, taking the plane where the screen of the client is located as a reference, when the client is moving, the coordinate system can be kept consistent with the client, so that the speed information on the multiple coordinate axes can better represent the motion state of the client.

[0021] Combined with the first aspect, in a possible implementation manner, the determining the first distance threshold based on the motion state of the client includes:

[0022] In the case that the camera at the vehicle end does not recognize the user corresponding to the client, determining the first distance threshold based on the motion state of the client.

[0023] Combined with the first aspect, in a possible implementation manner, the method further includes:

[0024] In the case that the camera recognizes the user, obtaining the distance between the user and the vehicle end and the moving speed of the user based on the radar and the camera; calculating the remaining time for the user to reach the vehicle end based on the distance between the user and the vehicle end and the moving speed of the user; and determining to execute the first operation when the remaining time is less than or equal to the first time threshold.

[0025] In the embodiments of the present application, the radar has a ranging function and can also be referred to as a ranging sensor. The radar can include a lidar, a millimeter-wave radar, etc. When the camera on the vehicle side recognizes the user corresponding to the client, the identity of the user corresponding to the digital key can be identified, the distance can be located, and the speed can be measured based on the combination of multiple sensors on the vehicle side (such as a camera, a lidar, a millimeter-wave radar, etc.), so as to obtain the accurate remaining time for the user to reach the vehicle side. Moreover, the first communication device determines whether to perform the first operation by comparing the remaining time with a preset time threshold, so as to ensure that the execution timing of the first operation is consistent with the expectation, and achieve accurate function response and reasonable timing.

[0026] In combination with the first aspect, in a possible implementation manner, the first time threshold is determined by the time required to perform the first operation.

[0027] In the embodiments of the present application, the first time threshold is determined by the time required to perform the first operation. For example, the first time threshold is greater than or equal to the time required to perform the first operation, which can better control the execution timing of the first operation by the vehicle side and avoid the vehicle performing the first operation too early or too late.

[0028] In combination with the first aspect, in a possible implementation manner, the method further includes:

[0029] Determine the spatial distance between the client and the vehicle side based on the placement state of the client.

[0030] In the embodiments of the present application, the placement state of the client can represent the signal shielding degree or signal transmission loss in the spatial environment where the client is located. When the client is in different placement states, the signal shielding degree is different and the signal transmission loss is different. The placement state of the client will affect the signal strength of the wireless communication (such as Bluetooth or ultra-wideband) between the client and the vehicle side. For example, at the same spatial distance, when the client is in different placement states, the signal strength of the wireless communication between the client and the vehicle is different. Therefore, when the first communication device determines the spatial distance between the client and the vehicle side based on the signal strength, combining the placement state of the client can obtain a more accurate spatial distance between the vehicle and the client.

[0031] In combination with the first aspect, in a possible implementation manner, the determining the spatial distance between the client and the vehicle side based on the placement state of the client includes:

[0032] Determine the mapping relationship between the signal strength and the spatial distance based on the placement state of the client; determine the spatial distance between the client and the vehicle side based on the mapping relationship between the signal strength and the spatial distance and the signal strength between the vehicle side and the client.

[0033] In the embodiments of the present application, when the placement state of the client is different, the mapping relationship between the signal strength and the spatial distance is different. The first communication device can determine the mapping relationship corresponding to the current placement state of the client, and obtain the spatial distance that matches the signal strength between the client and the vehicle terminal according to this mapping relationship, thereby improving the accuracy of the obtained spatial distance between the client and the vehicle terminal.

[0034] In combination with the first aspect, in a possible implementation manner, the first communication device is the vehicle terminal, and the method further includes: receiving first information, where the first information includes the motion state of the client.

It can be understood that by combining the speed information of the client in each direction, an accurate motion state of the client can be obtained.

[0042] In combination with the second aspect, in a possible implementation manner, the speed information includes the acceleration and angular velocity of the client on the multiple coordinate axes.

[0043] In combination with the second aspect, in a possible implementation manner, the multiple coordinate axes include a first coordinate axis, a second coordinate axis, and a third coordinate axis.

[0114] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0115] In the description, claims, and drawings of this application, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device, etc. that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices, etc.

[0116] As used herein, "embodiment" means that the specific features, structures, or characteristics described in connection with the embodiment may be included in at least one embodiment of this application. The phrase appears in various places in the description and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art can explicitly and implicitly understand that, in the various embodiments of this application, if there is no special description and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0117] It should be noted that in this application, prefix words such as "first" and "second" are only used to distinguish different described objects, and have no restrictive effect on the position, order, priority, quantity, or content of the described objects. For example, if the described object is "field", the ordinal words before "field" in "first field" and "second field" do not limit the position or order between the "fields", and "first" and "second" do not limit whether the "fields" they modify are in the same message, nor do they limit the order of "first field" and "second field". Another example, if the described object is "level", the ordinal words before "level" in "first level" and "second level" do not limit the priority between the "levels". Another example, the quantity of the described object is not restricted by the prefix word and can be one or more. Taking "first device" as an example, the quantity of "device" therein can be one or more. In addition, the objects modified by different prefix words can be the same or different. For example, if the described object is "device", "first device" and "second device" can be the same device, devices of the same type, or devices of different types; another example, if the described object is "information", "first information" and "second information" can be information of the same content or information of different content. In short, the use of prefix words for distinguishing described objects in the embodiments of this application does not constitute a restriction on the described objects, and the description of the described objects refers to the description in the claims or the context of the embodiments, and should not constitute an unnecessary restriction due to the use of such prefix words.

[0118] It should be noted that in the embodiments of the present application, descriptions such as "at least one (or at least one) of a1, a2,..., and an" include the case where any one of a1, a2,..., and an exists alone, and also include any combination of any number of a1, a2,..., and an, and each case can exist alone. For example, the description "at least one of a, b, and c" includes the cases of a alone, b alone, c alone, the combination of a and b, the combination of a and c, the combination of b and c, or the combination of a, b, and c.

[0119] It should be understood that in the present application, "at least one (item)" means one or more, "multiple" means two or more, "at least two (items)" means two or three or more, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships can exist. For example, "A and / or B" can represent: only A exists, only B exists, and both A and B exist at the same time. Among them, A and B can be singular or plural. The character " / " generally represents an "or" relationship between the front and back associated objects. "At least one (one)" or its similar expression refers to any combination of these items, including any combination of single item (one) or plural items (ones). For example, at least one (one) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0120] The method provided by the present application can be applied to various communication systems. For example, it can be an Internet of Things (IoT) system, a Narrow Band Internet of Things (Nb-IoT) system, a Long Term Evolution (LTE) system, a short-range wireless communication network system, such as a Sparklink communication network system (including the basic version of Sparklink (Sparklink Basic, Slb) and the low-power version of Sparklink (Sparklink Low Energy, Sle)), Bluetooth Low Energy (BLE), or it can also be a 5th-Generation (5G) communication system, as well as new communication systems (such as 6G) emerging in the future development of communication. Among them, Slb of Sparklink is also known as "Technical Requirements and Test Methods for Wireless Short-Range Communication Vehicle Air Interface", and Sle of Sparklink is also known as "Technical Requirements and Test Methods for Low-Power Air Interface of the Access Layer of Sparklink Wireless Communication System".

[0121] The technical solution provided by this application can also be applied to Machine Type Communication (Mtc), Long Term Evolution - Machine (Lte - M), Device - To - Device (D2D) network, Machine To Machine (M2M) network, Internet Of Things (Iot) network or other networks. Among them, the Iot network can include, for example, the vehicle - to - everything network. Among them, the communication methods in the vehicle - to - everything network system are collectively referred to as Vehicle - To - Everything (V2X, where X can represent anything). For example, the V2X can include: Vehicle To Vehicle (V2V) communication, Vehicle To Infrastructure (V2I) communication, communication between vehicle and pedestrian (vehicle to pedestrian, V2P), or communication between vehicle and network (vehicle to network, V2N), etc.

[0122] Please refer to Figure 1 , Figure 1 which is an example of the structural schematic diagram of a communication system provided by an embodiment of this application. As Figure 1 shown, the communication system can include a client and a vehicle terminal. It should be understood that the client in the embodiment of this application can be a smart phone, a notebook, a wearable device (such as a smart bracelet, a smart watch, etc.). The vehicle terminal in the embodiment of this application can include a vehicle in the vehicle - to - everything network (such as a whole vehicle), an in - vehicle device or an in - vehicle terminal in the vehicle - to - everything network, etc.

[0123] Digital keys can adopt communication technologies such as Near Field Communication (NFC), Bluetooth Low Energy (BLE), and Ultra Wide Band (UWB), and through the corresponding client, implement functions such as opening the car door, closing the car door, starting the engine, and adjusting the seat of the traditional car key. Exemplarily, the client corresponding to the digital key can determine the spatial distance between the digital key and the vehicle according to the Received Signal Strength Indication (RSSI) of Bluetooth or the Time of Flight (TOF) of Ultra Wide Band, and distinguish different functional areas according to different spatial distance thresholds, such as the welcome area and the unlocking area, etc. When the spatial distance between the digital key and the vehicle end is less than or equal to the distance threshold corresponding to the functional area, the vehicle end executes the operation corresponding to the functional area. Figure 2 This is an example of the division of functional areas provided by the embodiments of the present application, such as Figure 2 As shown, the functional area can include an unlocking area, a welcome area, a UWB start area, and a BLE sensing area. Among them, the spatial distance threshold corresponding to the unlocking area is 3 meters, that is, when the spatial distance between the digital key and the vehicle end is less than or equal to 3 meters, the vehicle end executes the operation corresponding to the unlocking area (such as opening the car door, adjusting the seat, etc.). The spatial distance threshold corresponding to the welcome area is 10 meters, the spatial distance threshold corresponding to the UWB start area is 20 meters, and the spatial distance corresponding to the BLE sensing area is 60 meters.

[0124] It can be understood that Figure 2 The division of the functional areas shown and the spatial distance thresholds corresponding to each functional area are only examples, and the division of the functional areas shown and the spatial distance thresholds corresponding to each functional area should not be understood as a limitation on the embodiments of the present application. Figure 2 The division of the functional areas shown and the spatial distance thresholds corresponding to each functional area are only examples, and the division of the functional areas shown and the spatial distance thresholds corresponding to each functional area should not be understood as a limitation on the embodiments of the present application.

[0125] In the above method, the timing for the vehicle end to perform the operations corresponding to the functional area is determined by the spatial distance threshold corresponding to the functional area. When the distance threshold corresponding to the functional area is set unreasonably, the timing for the vehicle to perform the operations corresponding to the functional area does not match the expectation. For example, when a user runs quickly towards the vehicle, the moving speed of the digital key is relatively fast, and the time from reaching the spatial distance threshold corresponding to the unlocking area to beside the vehicle door will be earlier than normal walking. At this time, the vehicle unlocking action may not be completed, for example, the door handle may not pop out in time, or the seat may not be adjusted in place, that is, the timing for the vehicle to perform the operations corresponding to the functional area does not match the expectation, resulting in a lag in the user experience and thus affecting the user experience. In addition, depending on the different ways the user carries the client corresponding to the digital key (such as different placement positions, different orientations, etc.), the signal transmission of the digital key may be blocked to varying degrees, resulting in changes in the signal strength indication of Bluetooth or the time of flight of ultra-wideband, thereby affecting the accuracy of the spatial distance between the digital key and the vehicle end, and causing the vehicle function response not to match the expectation.

[0126] In view of this, embodiments of the present application provide a vehicle processing method, an information processing method, a communication device, and a system, which can ensure that the timing for the vehicle to perform corresponding operations matches the expectation and avoid the vehicle from performing corresponding operations too early or too late. The method provided by the embodiments of the present application can be applied to Figure 1 the communication system shown in

[0127] Please refer to Figure 3A , Figure 3A which is a schematic structural diagram of a vehicle end and a client provided by an embodiment of the present application. As Figure 3A shown, the client may include a sensor module, a communication module, and a setting module. Among them, the sensor module is used to collect various sensor signals of the client, including but not limited to angular velocity, acceleration, distance, and illumination. These sensor signals are used to identify the current state of the client, such as the moving speed and placement position of the client. The communication module is used to establish a BLE or UWB connection with the vehicle end, and for spatial distance positioning and signal transmission. The setting module is used to set the distance thresholds corresponding to different functional areas. For example, the setting module can provide the setting of the distance thresholds for different functional areas through the digital key application (APP) interface and save the set distance thresholds for subsequent functional area judgment.

[0128] The vehicle end can include a sensor module, a communication module, a digital key chip, and a Body Control Module (BCM) chip. The sensor module is used to collect various sensor signals at the vehicle end, including but not limited to cameras, millimeter-wave radars, lidars, etc. These sensor signals are used to identify the current state of the client corresponding to the digital key, such as the orientation of the client relative to the vehicle end and the moving speed towards the vehicle end. The communication module is used to establish BLE and UWB connections with the client, as well as for spatial distance positioning and signal transmission. The digital key chip is used to receive information from other modules, determine the spatial distance between the current client and the vehicle end or the remaining time from the client to the vehicle end, and determine the switching of the function area, and send the instruction for the function area switching to the BCM chip. The BCM chip is used to perform corresponding operations according to the instructions of the digital key chip, such as lighting control, seat control, door control, audio control, etc., to control different functions of the vehicle end.

[0129] Optionally, the vehicle end can further include a setting module for setting the spatial distance threshold or time threshold. The setting module can be deployed in the vehicle head unit interface of the vehicle end. It can be understood that the description of this setting module can be as detailed as the setting module in the client.

[0130] Exemplarily, the client or the vehicle end can also include a function area response module. The function area response module can identify the motion state and placement state of the client based on the sensor signals and communication signals, and determine the function area response strategy according to the motion state and placement state of the client. As Figure 3B shown, the function area response strategy can include the determination of the distance threshold and the determination of the mapping relationship between the signal strength and spatial distance between the vehicle end and the client. For example, the function area response module can adjust the distance threshold corresponding to the function area according to the motion state of the client and the distance threshold set by the setting module. The function area response module can also adjust the mapping relationship between the signal strength and spatial distance between the client and the vehicle end according to the placement state of the client to ensure the accuracy of the spatial distance between the client and the vehicle end. For example, the function area response module can select the mapping relationship between the signal strength and spatial distance that matches the current placement state of the client from the mapping relationship library of signal strength and spatial distance. The mapping relationship library can include multiple mapping relationships between signal strength and spatial distance.

[0131] The function area response module can determine the mapping relationship between the signal strength and the function area according to the current mapping relationship between the signal strength and spatial distance and the distance threshold corresponding to the function area, for the digital key chip to judge the currently belonging function area and send corresponding instructions to the BCM chip to perform corresponding operations.

[0132] Optionally, the ribbon response module can also calculate the remaining time from the client to the vehicle end based on the current moving speed of the client and the spatial distance from the client to the vehicle end, and compare the remaining time with the time distance threshold to determine the current digital key function area.

[0133] Please refer to Figure 4 , Figure 4 which is a schematic flow chart of a vehicle operation method provided by an embodiment of the present application. This method can be applied to a first communication device, and the first communication device can be the client or the vehicle end described above (such as Figure 3A shown). As Figure 4 shown, the method includes but is not limited to the following steps.

[0134] 401. Determine a first distance threshold based on the motion state of the client, where the motion state of the client corresponds to the moving speed of the client.

[0135] Exemplarily, the client is the client corresponding to the digital key, and the first distance threshold is the distance threshold corresponding to the first operation or the first function area. When the spatial distance between the client and the vehicle end satisfies the distance threshold, the vehicle performs the first operation to implement the function of the first function area. The motion state of the client corresponds to the moving speed of the client, and the moving speed corresponding to the client in different motion states is different. For example, when the moving speed of the client is within the first value range, the client is in the first motion state. When the moving speed of the client is within the second value range, the client is in the second motion state.

[0136] For example, the motion state of the client can be any one of running, normal walking, or slow walking. Among them, the moving speed corresponding to the running motion state of the client is greater than the moving speed corresponding to the normal walking motion state of the client.

[0137] Exemplarily, the greater the moving speed corresponding to the motion state of the client, the greater the first distance threshold.

[0138] In a possible implementation manner, the first communication device can obtain the coefficient corresponding to the motion state of the client, and determine the first distance threshold based on the coefficient and the second distance threshold, where the second distance threshold is the distance threshold corresponding to the first operation when the client is in the reference motion state. Or, the second distance threshold is the distance threshold corresponding to the first function area when the client is in the reference motion state.

[0139] Exemplarily, the coefficient can be used to characterize the moving speed corresponding to the motion state of the client. The coefficient corresponding to the motion state of the client is positively correlated with the moving speed corresponding to the motion state. For example, the greater the moving speed corresponding to the motion state, the greater the coefficient. The smaller the moving speed corresponding to the motion state, the smaller the coefficient corresponding to the motion state.

[0140] Exemplarily, the reference motion state may be a preset motion state. The reference motion state may be a possible motion state of the client. For example, the reference motion state may be normal walking. The second distance threshold is preset. For example, the second distance threshold may be set by the setting module in the vehicle end or the client as shown in Figure 3A . The first communication device may store the second distance threshold. After determining the coefficient corresponding to the current motion state of the client, the first communication device determines the first distance threshold according to the coefficient and the second distance threshold.

[0141] It can be understood that in the embodiments of the present application, the distance threshold corresponding to the first operation is adjusted based on the motion state of the client. The second distance threshold can also be understood as the distance threshold corresponding to the first operation before adjusting the distance threshold corresponding to the first operation.

[0142] Exemplarily, the coefficient is positively correlated with the first distance threshold. That is, the larger the coefficient, the larger the first distance threshold; the smaller the coefficient, the smaller the first distance. For example, the first distance threshold is the product of the coefficient and the second distance threshold.

[0143] For example, the second distance threshold is T1 = 10m. When the motion state of the client is running, the coefficient K1 = 2.5 corresponding to the motion state, and the first distance threshold is T1 = T2 * K1 = 25m. When the motion state of the client is normal walking, the coefficient K2 = 1 corresponding to the motion state, and the first distance threshold is T1 = T2 * K2 = 10m. When the motion state of the client is slow walking, the coefficient K3 = 0.7 corresponding to the motion state, and the first distance threshold is T1 = T2 * K1 = 7m.

[0144] It can be understood that the first communication device may also store the spatial distance threshold corresponding to other operations in the reference motion state. For example, the first communication device may store the spatial distance threshold corresponding to the second operation in the reference motion state, and the first communication device may also determine the spatial distance threshold corresponding to the second operation in the current motion state of the client based on the coefficient and the spatial distance threshold corresponding to the second operation in the reference motion state.

[0145] It can be understood that the above running, normal walking, and slow walking are only some possible examples of the motion state of the client, and should not be construed as a limitation on the embodiments of the present application.

[0146] In a possible implementation manner, the motion state of the client is determined by the speed information of the client on multiple coordinate axes.

[0147] Exemplarily, the multiple coordinate axes may be the coordinate axes in a coordinate system determined based on the plane where the client's screen is located. For example, the multiple coordinate axes include a first coordinate axis, a second coordinate axis, and a third coordinate axis. The first coordinate axis and the second coordinate axis are parallel to the plane where the client's screen is located, and the third coordinate axis is perpendicular to the plane where the client's screen is located. As Figure 5 shown, the X-axis in the coordinate system may extend horizontally to the right based on the default screen direction of the client, the Y-axis extends vertically upward from the plane where the screen is located, and the Z-axis extends outward perpendicular to the screen.

[0148] Exemplarily, the above speed information may include the acceleration and angular velocity of the client on the multiple coordinate axes. The speed information may be collected by an acceleration sensor of the client. For example, the acceleration sensor collects the acceleration and angular velocity of the client on the X-axis, Y-axis, and Z-axis at a frequency of 100 Hertz (Hz), so as to obtain the speed information.

[0149] In a possible implementation manner, Figure 4 the method shown further includes step 402.

[0150] 402. Determine the spatial distance between the client and the vehicle end based on the placement state of the client.

[0151] In this implementation manner, the placement state of the client may characterize the degree of signal occlusion or signal transmission loss in the spatial environment where the client is located. When the client is in different placement states, the degree of signal occlusion is different, and the signal transmission loss is different. For example, the placement state of the client may include being held in the hand, in a pants pocket, or in a backpack, etc. The degree of signal occlusion (or transmission loss) of the client when held in the hand is less than the degree of signal occlusion (or transmission loss) of the client when in a pants pocket or backpack state. Therefore, the placement state of the client will affect the signal strength of the wireless communication (such as Bluetooth or ultra-wideband) between the client and the vehicle end. For example, at the same spatial distance, when the client is in different placement states, the signal strength of the wireless communication between the client and the vehicle is different. Therefore, when the first communication device determines the spatial distance between the client and the vehicle end based on the signal strength, combining the placement state of the client can obtain a more accurate spatial distance between the vehicle and the client.

[0152] Exemplarily, the first communication device may determine the mapping relationship between the signal strength and the spatial distance based on the placement state of the client, and determine the spatial distance between the client and the vehicle end based on the mapping relationship between the signal strength and the spatial distance, and the signal strength between the vehicle end and the client.

[0153] Exemplarily, the mapping relationship between the signal strength and the spatial distance can be pre-stored in the memory (such as a non-volatile memory) of the first communication device. For example, multiple mapping relationships between the signal strength and the spatial distance can be stored in the memory of the first communication device. The first communication device can select a mapping relationship that matches the current placement state from the multiple mapping relationships based on the current placement state, then obtain the current signal strength between the client and the vehicle end, and obtain the spatial distance that matches the current signal strength according to the mapping relationship.

[0154] 403, when the spatial distance between the client and the vehicle end is less than or equal to the first distance threshold, it is determined to execute the first operation.

[0155] Exemplarily, when the first communication device is the vehicle end, the first communication device executes the first operation. When the first communication device is the client, the first communication device sends the first indication information to the vehicle end, and the first indication information is used to instruct the vehicle end to execute the first operation.

[0156] In the embodiments of the present application, when the client is in different motion states, the motion speed of the client is different. When the spatial distance between the client and the vehicle end is the same, due to different motion states of the client, the remaining time from the client to the vehicle end is different. Therefore, the first communication device can determine a more reasonable first distance threshold based on the motion state of the client, taking into account the remaining time from the client to the vehicle end, ensuring that the timing of the vehicle executing the first operation is consistent with the expectation, avoiding the vehicle executing the first operation too early or too late, and thus better controlling the timing of the vehicle end function response. For example, when the user runs towards the vehicle end, the vehicle end can start the welcome and unlocking actions earlier than normal walking to ensure timely function response.

[0157] Please refer to Figure 6 , Figure 6 is a schematic flowchart of another vehicle operation method provided by the embodiments of the present application. This method is applied to the first communication device, and the first communication device can be the vehicle end described above. As Figure 6 shown, this method includes but is not limited to the following steps.

[0158] Optionally, Figure 6 the method shown can include step 601 and step 602.

[0159] 601, monitor the Bluetooth connection status between the vehicle end and the client.

[0160] 602, determine whether a Bluetooth connection is established between the vehicle end and the client. If not, execute step 601 to continue monitoring the Bluetooth connection status between the vehicle end and the client. If so, execute step 603.

[0161] 603. Determine whether the camera at the vehicle end recognizes the user corresponding to the client. If so, execute step 604; if not, execute step 607.

[0162] Exemplarily, when a Bluetooth connection is established between the client and the vehicle end, it indicates that the user is near the vehicle end. Therefore, the vehicle end can recognize the user from the surrounding of the vehicle body based on the camera at the vehicle end. For example, the camera at the vehicle end can recognize the user from the crowd in the 360° panoramic view around the vehicle body based on the face recognition algorithm.

[0163] In a possible implementation manner, the first communication device can determine whether the user is recognized based on the occlusion degree of the user in the image obtained by the camera at the vehicle end. For example, when the occlusion degree of the user in the image is greater than or equal to the first threshold (such as 50%), the accuracy of the distance between the user and the vehicle end measured by the radar is low. Therefore, the first communication device can determine that the camera at the vehicle end does not recognize the user, and thus determine to execute the first operation based on step 607, step 608, and step 609. When the occlusion degree of the user in the image is less than the first threshold, the accuracy of the distance between the user and the vehicle end measured by the radar is high. Therefore, the first communication device determines that the camera at the vehicle end recognizes the user, and thus determines to execute the first operation based on step 604, step 605, and step 606.

[0164] It can be understood that the present application does not limit the specific method for the camera to recognize the user, and deep learning algorithms such as convolutional neural networks and long short-term memory networks can be adopted.

[0165] 604. Based on the radar and the camera, obtain the distance between the user and the vehicle end and the moving speed of the user.

[0166] Exemplarily, the radar has a ranging function and can also be called a ranging sensor. The radar can include lidar, millimeter wave radar, etc. The radar can be set in the vehicle end. When the camera at the vehicle end recognizes the user corresponding to the client, the first communication device can determine the azimuth angle of the user based on the camera at the vehicle end. Then, the first communication device can measure the distance between the user and the vehicle in the direction corresponding to the azimuth angle based on the radar at the vehicle end, and determine the moving speed of the user through the change in the distance between the user and the vehicle end within a period of time.

[0167] For example, let D′ be the change in the distance between the user and the vehicle end within a period of time Δt, then the moving speed of the user is

[0168] In some possible implementations, the azimuth angle of the user can also be determined based on the signal information of multiple UWB anchors and algorithms such as Time Difference of Arrival (TDOA) and Two Way Ranging (TWR).

[0169] 605. Calculate the remaining time for the user to reach the vehicle end based on the distance between the user and the vehicle end and the moving speed of the user.

[0170] Exemplarily, the first communication device can calculate the remaining time for the user to reach the vehicle based on the current distance D between the user and the vehicle end and the moving speed v of the user.

[0171] 606. When the remaining time is less than or equal to the first time threshold, determine to execute the first operation.

[0172] Exemplarily, the first time threshold can be preset, or the first time threshold can be determined by the time required to execute the first operation. For example, the first time threshold is greater than or equal to the time required to execute the first operation.

[0173] Exemplarily, the first time threshold can also correspond to the first functional area. When the remaining time is less than or equal to the first time threshold, the first communication device determines to execute the first operation to implement the function of the first functional area.

[0174] In the embodiments of the present application, when the camera at the vehicle end recognizes the user corresponding to the client, the user corresponding to the digital key can be identified for identity, distance positioning, and speed measurement based on the combination of multiple sensors at the vehicle end, so as to obtain the accurate remaining time for the user to reach the vehicle end. For example, the image information obtained by the camera has rich features such as texture and color. Therefore, the camera at the vehicle end can accurately identify the azimuth angle of the user from the crowd in the 360° panoramic view around the vehicle body. Based on the accuracy of the distance measurement by sensors such as lidar and millimeter-wave radar, the distance between the user and the vehicle end and the moving speed of the user can be accurately obtained. In addition, the first communication device determines whether to execute the first operation by comparing the remaining time with a preset time threshold, so as to ensure that the execution timing of the first operation is consistent with the expectation, and achieve accurate function response and reasonable timing.

[0175] 607. Determine the first distance threshold based on the motion state of the client.

[0176] When the camera at the vehicle end does not recognize the user, the vehicle end can identify the spatial distance between the vehicle end and the client based on the signal strength of Bluetooth or ultra-wideband.

[0177] Optionally, Figure 6 The method shown also includes step 608.

[0178] 608. Determine the spatial distance between the client and the vehicle end based on the placement state of the client.

[0179] 609. When the spatial distance between the client and the vehicle end is less than or equal to the first distance threshold, determine to execute the first operation.

[0180] It can be understood that for the specific implementation manners of step 607, step 608, and step 609, reference can be made to Figure 4 the specific implementation manners of step 401, step 402, and step 403 in , which will not be elaborated here.

[0181] In the embodiments of the present application, when the camera at the vehicle end does not recognize the user corresponding to the client, the first communication device can determine the first distance threshold based on the motion state of the client, and thus determine the execution timing of the first operation based on the first distance threshold, ensuring that the timing of the vehicle executing the first operation is consistent with the expectation, avoiding the vehicle executing the first operation too early or too late, and thus better controlling the response timing of the vehicle end function.

[0182] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of an information processing method provided by the embodiments of the present application. This method is applied to the second communication device, and the second communication device can be the client described above. As Figure 7 shown, this method includes but is not limited to the following steps.

[0183] Optionally, Figure 7 the method shown includes steps 701, 702, and 703.

[0184] 701. Monitor the Bluetooth connection status between the client and the vehicle end.

[0185] 702. Determine whether a Bluetooth connection is established between the client and the vehicle end. If not, execute step 701 to continue monitoring the Bluetooth connection status between the vehicle end and the client. If so, execute step 703.

[0186] 703. Obtain the speed information of the client on multiple coordinate axes.

[0187] This speed information includes the acceleration and angular velocity of the client on multiple coordinate axes. The multiple coordinate axes include a first coordinate axis, a second coordinate axis, and a third coordinate axis. The first coordinate axis and the second coordinate axis are parallel to the plane where the screen of the client is located, and the third coordinate axis is perpendicular to the plane where the screen of the client is located.

[0188] Exemplarily, the speed information can be collected by an acceleration sensor on the client. The acceleration sensor can collect the acceleration and angular velocity of the client on the first coordinate axis, the second coordinate axis, and the third coordinate axis at a sampling frequency. The speed information can include the acceleration and angular velocity of the client on the first coordinate axis, the second coordinate axis, and the third coordinate axis within a period of time (e.g., 1 second). For example, when the sampling frequency is 100 Hz, the speed information can include 100 sampling data of the client on the three coordinate axes within 1 second (i.e., the acceleration and angular velocity on the three coordinate axes).

[0189] It can be understood that for the specific description of the speed information and multiple coordinate axes, reference can be made to Figure 4 step 401 in Figure 5 or the relevant description in

[0190] 704, and the motion state of the client is determined based on the speed information of the client on multiple coordinate axes.

[0191] In a possible implementation manner, the motion state of the client is determined based on the speed information and the first classification model. The first classification model is trained by the first data set, and the first data set includes the speed information of the client on multiple coordinate axes when the client is in different motion states.

[0192] Exemplarily, the first classification model can be deployed in the client. The second communication device can input the speed information into the first classification model, so that the first classification model outputs the motion state of the client (such as running, normal walking, slow walking, etc.). The first classification model can include a neural network model, a support vector machine model, or a decision tree, etc. For example, when the first classification model is a neural network model, the neural network model can be a one-dimensional convolutional neural network, including a series of one-dimensional convolutional layers, pooling layers, and fully connected layers.

[0193] Exemplarily, before determining the motion state of the client based on the first classification model, it is necessary to train the first classification model based on the first data set. The first data set includes multiple speed information and the motion states respectively corresponding to the multiple speed information. Any one of the multiple speed information includes the acceleration and angular velocity of the client on multiple coordinate axes.

[0194] For example, the first data set D is expressed as D = {(X1, Y1), (X2, Y2), …, (X n , Y n )}, where X i ∈R L×FFor the speed information of the client, L is the number of sampling data corresponding to the speed information. L is determined by the sampling frequency of the acceleration sensor and the sampling time corresponding to the speed information. For example, if the sampling frequency of the acceleration sensor is 100 Hz and the speed information includes the speed information of the client within 1 second, then L is 100. F is the number of input feature channels, and each input feature channel is used to represent a type of input data. For example, the speed information of the client includes the acceleration and angular velocity of the client on three coordinate axes, and F can be 6, where one input feature channel represents the angular velocity or acceleration of the client on one coordinate axis. Y i ∈R 1×c is the motion state corresponding to the speed information (which can also be understood as the data label) and can be one-hot encoded. C is the number of categories of motion states, representing C kinds of motion states respectively. For example, the motion states of the client can include running, normal walking, and slow walking, then C is 3. Using this data set to train the first classification model, the optimization objective of the first classification model is:

[0195]

[0196] where M is the first classification model, w is the trainable parameter in the first classification model, and l is the loss function for training the first classification model.

[0197] Exemplarily, a stochastic gradient descent optimizer and cross-entropy loss can be used to optimize the parameters of the first classification model on a high-performance computer until the loss converges, save the parameters of the first classification model, and deploy the first classification model on the client.

[0198] Optionally, Figure 7 the method shown may include step 705.

[0199] 705. Determine the placement state of the client based on the speed information.

[0200] Exemplarily, the second communication device can determine the placement state of the client based on the speed information and the second classification model. The second classification model is trained from a second data set. The second data set includes multiple speed information and the placement states respectively corresponding to the multiple speed information. Any one of the multiple speed information includes the acceleration and angular velocity of the client on multiple coordinate axes.

[0201] Exemplarily, the second classification model has the same input data and network structure as the first classification model, but different data labels and output categories in the training dataset. For example, in the first dataset used to train the first classification model, both the data label and the output category of the first classification model are the motion states of the client (such as running, normal walking, or slow walking), while in the second dataset used to train the second classification model, both the data label and the output category of the second classification model are the placement states of the client (such as held in hand, in the pocket, or in the backpack).

[0202] In a possible implementation, the second communication device can first determine whether the client is in a stationary state. For example, when the acceleration of the client on multiple coordinate axes is less than a second threshold and the angular velocity of the client on multiple coordinate axes is less than a third threshold (such as the acceleration on multiple coordinate axes is less than 0.5 m / s 2 and the angular velocity on multiple coordinate axes is less than 0.1 rad / s), the second communication device determines that the client is in a stationary state, and the current placement state of the client is the same as the previously recognized placement state. When the acceleration of the client on any coordinate axis is greater than or equal to the second threshold, or the angular velocity of the client on any coordinate axis is greater than or equal to the third threshold, the second communication device can determine the current motion state of the client based on the first classification model and the placement state of the client based on the second classification model.

[0205] Optionally, the first message can further include the placement state of the client, so that the vehicle end can obtain a more accurate spatial distance between the vehicle and the client based on the placement state of the client.

[0206] In the embodiments of the present application, accurate motion state and placement state of the client can be obtained based on the velocity information of the client on multiple coordinate axes.
