[0026] In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the following will briefly introduce the drawings needed to be used in the embodiments description. Obviously, the drawings in the following description are only some examples or embodiments of the present specification, and for those skilled in the art, the present specification can also be applied to other similar scenarios without creative labor. Unless it is clear from the language context or otherwise indicated, the same reference numbers in the drawings represent the same structure or operation.

[0027] It should be understood that the "system", "device", "unit" and / or "module" used herein is a method for distinguishing different components, elements, parts, sections or assemblies at different levels. However, if other words can achieve the same purpose, the words can be replaced by other expressions.

[0028] As shown in the specification and claims, unless the context clearly indicates otherwise, "one", "a", "an", and / or "the" do not specify a single number, but can also include a plurality. Generally, the terms "comprise" and "include" only indicate the inclusion of the steps and elements explicitly identified, and these steps and elements do not constitute an exclusive list, and the method or device can also include other steps or elements.

[0029] Although the present specification makes various references to certain modules or units in the system according to the embodiments of the present specification, however, any number of different modules or units can be used and run on the client and / or server. The modules are only illustrative, and different aspects of the system and method can use different modules.

[0030] Flowcharts are used in the specification to illustrate the operations of systems in accordance with embodiments of the specification. It should be understood that the operations in the figures need not necessarily be performed in the order shown. Rather, the order of the steps can be reversed or performed concurrently. Additionally, other operations can be added or removed from the processes.

[0031] Currently, when the control device (e.g., intelligent central control) of a shared vehicle (e.g., shared bicycle, shared electric bicycle, etc.) communicates with a cloud server, it is mainly achieved through mobile communication networks such as NB-IoT, 2G, LTE, etc. With the increase of shared vehicles, for example, the increase of the number of shared vehicles put into use, the point-to-point communication mode may cause the congestion of the communication base station resources of the operator, so that the control device and the cloud server are difficult to establish a communication connection or the communication connection is disconnected. In this case, the cloud server will lose contact with the vehicle and cannot obtain vehicle information and / or control the vehicle state, affecting the normal use of the shared vehicle. For example, the server cannot control the vehicle to lock, resulting in the user being unable to return the vehicle.

[0032] The present application proposes a communication method of a vehicle, which can establish a Bluetooth connection with other intelligent central controls that can normally communicate with the cloud server when the intelligent central control of the vehicle and the cloud server are disconnected, so as to realize communication with the cloud server. The vehicle communication method provided by the embodiments of the present specification can make the shared vehicle maintain data communication with the cloud server in the case of mobile communication network congestion, weak network signal, or closed mobile network communication module, so as to guarantee the normal service of the shared vehicle.

[0033] The vehicle position and / or trajectory in the present application can be obtained by positioning technology embedded in the vehicle. In some embodiments, the position of the vehicle can be obtained by real-time tracking through the positioning technology. The positioning technology used in the present application can include one of global positioning system (GPS), global satellite navigation system (GLONASS), Beidou navigation system (COMPASS), Galileo positioning system (GLONASS), quasi-zenith satellite system (QZSS), base station positioning technology, wireless fidelity (Wi-Fi) positioning technology, etc., or any combination thereof. One or more of the above positioning technologies can be used interchangeably in the present application.

In some embodiments, the first acquisition module 210, the first determination module 220, and the first communication module 230 can be different modules in a system, or can be a module that implements the functions of two or more modules described above. In some embodiments, the first acquisition module 210, the first determination module 220, and the first communication module 230 can share a storage module, and each module can also have its own storage module. In some embodiments, the system 200 can include a positioning module for acquiring position information of the vehicle. Variations such as this are within the scope of protection of the present specification.

[0060] Figure 3 is an exemplary module diagram of a vehicle communication system according to other embodiments of the present specification.

[0061] As shown in Figure 3 , in some embodiments, the vehicle communication system 300 can include a second acquisition module 310, a second determination module 320, and a second communication module 330. These modules can be implemented as an application program or a set of instructions read and executed by a processing engine. In addition, the modules can be any combination of hardware circuits and applications / instructions. For example, when the processing engine or processor executes the application program / set of instructions, the module can be part of the processor. In some embodiments, the system 300 can be part of the server 110 (e.g., the processing device 112).

[0062] The second acquisition module 310 can be configured to acquire, by a second vehicle, first target information sent by a first vehicle, wherein the first target information can include authentication information of the first vehicle. For example, when the communication connection state between the intelligent central control of the first vehicle and the cloud server is disconnected, the second acquisition module 310 can acquire the authentication information of the first vehicle through the first intelligent central control of the second vehicle. In some embodiments, the second acquisition module 310 can be configured to acquire information such as the positioning position, the lock state, and the use state of the vehicle, which is not limited in the present specification.

[0063] The second determination module 320 can be configured to determine the legal state of the first vehicle, and authorize the first intelligent central control of the second vehicle to establish a communication connection with the intelligent central control of the first vehicle based on the determination result. In some embodiments, the second determination module 320 can further include a judgment unit 323 and an authorization unit 325.

[0064] The determining unit 323 can be configured to determine whether the vehicle is legal based on the authentication information of the first vehicle. For example, the determining unit 323 can query the authorization state of the vehicle in the database based on the vehicle identity in the authentication information, so as to determine whether the vehicle is legal. For example, for a legal vehicle, the authorization information corresponding to the vehicle can be found in the database, and for an illegal vehicle, the related information of the vehicle cannot be found. In some embodiments, the determining unit 323 can determine whether the vehicle identity is legal based on the vehicle identity in the authentication information and the authorization information by using a preset algorithm.

[0065] The authorization unit 325 can authorize the first intelligent central control of the second vehicle to establish a communication connection with the intelligent central control of the first vehicle in response to the vehicle being legal. In some embodiments, after determining that the vehicle is legal, the authorization unit 325 can send a signal allowing the first intelligent central control of the second vehicle to establish a communication connection with the intelligent central control of the first vehicle to the first intelligent central control of the second vehicle in response to the vehicle authentication information sent by the first intelligent central control of the second vehicle.

[0066] In some embodiments, after the first intelligent central control of the second vehicle successfully establishes a communication connection with the intelligent central control of the first vehicle, the second determining module 320 can update the related information of the first vehicle in the database, and mark that the intelligent central control of the first vehicle is attached to the first intelligent central control of the second vehicle, that is, the intelligent central control of the first vehicle communicates with the cloud server through the first intelligent central control of the second vehicle.

[0067] The second communication module 330 can be configured to send operation instructions to the intelligent central control of the first vehicle through the first intelligent central control of the second vehicle based on the vehicle marking table. In some embodiments, the second communication module 330 can communicate with the intelligent central control through a network, for example, a mobile communication network such as NB-IoT, 2G, LTE, etc.

[0068] In some embodiments, the vehicle marking table can reflect the vehicle authorization state, communication connection state, and other information corresponding to the vehicle. In some embodiments, the vehicle marking table can be stored in a system database (for example, the storage device 150) or an external database. For example, when the second communication module 330 needs to send operation instructions or other information to the first vehicle 130, and the communication connection between the second communication module 330 and the intelligent central control of the first vehicle 130 is disconnected, the second communication module 330 can query the vehicle marking table in the database to obtain the first intelligent central control connected to the first vehicle 130, and send operation instructions or other information carrying the identity information of the first vehicle 130 through the first intelligent central control.

[0069] It should be understood that, Figure 3The illustrated system and its modules can be implemented in various ways. For example, in some embodiments, the system 300 and its modules can be implemented in hardware, software, or a combination of software and hardware. The hardware components can be implemented with special logic, while the software components can be stored in memory and executed by a suitable instruction execution system, such as a microprocessor or dedicated design hardware. Those skilled in the art can understand that the above-described methods and systems can be implemented using computer-executable instructions and / or included in processor control code, such as provided on a carrier medium, such as a disk, CD or DVD-ROM, programmable memory, such as read-only memory (firmware), or data carrier, such as an optical or electronic signal carrier. The system of the present specification and its modules can be implemented not only in hardware circuitry, such as very large scale integrated circuits or gate arrays, semiconductors, such as logic chips, transistors, or programmable hardware devices, such as field programmable gate arrays, programmable logic devices, etc., but also in software, for example, executed by various types of processors, and in a combination of the above-mentioned hardware circuitry and software (e.g., firmware).

[0070] It should be noted that the above description of the system 300 and its modules is for the convenience of description and does not limit the present specification to the embodiments described. It can be understood that, after understanding the principles of the system, those skilled in the art can combine the modules in any way or connect the modules to form a subsystem without departing from the principles. In some embodiments, the second acquisition module 310, the second determination module 320, and the second communication module 330 can be different modules in a system, or they can be a module that implements the functions of two or more modules described above. In some embodiments, the system 300 can further include a storage module for storing various information and data, such as a vehicle marking table and / or state information of a vehicle. In some embodiments, the second acquisition module 310, the second determination module 320, and the second communication module 330 can share a storage module, and each module can also have its own storage module. Variations such as this are within the scope of the present specification.

[0071] Figure 4 is an exemplary flowchart of a vehicle communication method according to some embodiments of the present specification.

[0072] In some embodiments, the flow 400 can be performed by a processing device (e.g., Figure 1The processes described in FIG. 4 can be implemented in program instructions stored in a storage device (e.g., storage device 150) that are executed by a processing device (e.g., the processing device in the first vehicle 130). For example, the processes 400 can be stored in a storage device in the form of a program or instructions that, when executed by a processing device, can implement the processes 400. In some embodiments, the processes 400 can utilize one or more additional operations not described below, and / or can not complete with one or more of the operations discussed below. Additionally, the order of the operations shown is not limiting. Figure 4 The order of the operations shown is not limiting.

[0073] At step 410, a communication connection state with a cloud server is obtained.

[0074] The communication connection state (also referred to as a communication status) refers to a state of a data communication link between different devices being connected or disconnected. In some embodiments, the communication connection state being disconnected can include various states in which information cannot be normally transmitted, such as initial connection failure, connection interruption, and the like. For example, the communication connection between the intelligent center of the first vehicle 130 and the cloud server (e.g., server 110) can fail to establish an initial connection due to reasons such as mobile communication network congestion, mobile communication network module being closed, the cloud server reaching a maximum connection, and the like. For another example, the intelligent center of the second vehicle 140 can be disconnected from the cloud server (e.g., server 110) after an initial connection is established for a period of time due to reasons such as weak data signal strength of the mobile network or signal disappearance.

[0075] In some embodiments, the communication connection state can be obtained by a communication module of the vehicle, such as a mobile network communication module. In some embodiments, the communication connection state with the cloud server can be determined by periodically sending a heartbeat data packet to the cloud server. For example, the intelligent center of the first vehicle 130 or the second vehicle 140 can transmit a heartbeat data packet to the server 110 every 3 minutes, or every 5 minutes, or every 8 minutes, or every 15 minutes, and the like. If the intelligent center can normally obtain a response of the server 110 to the heartbeat data packet, it is determined that the vehicle is in a normal connection state with the server 110, and otherwise, it is determined that the vehicle is in an abnormal disconnected state.

[0076] In some embodiments, the communication connection state with the cloud server can be determined according to the signal strength of the mobile communication network. For example, when the intelligent center of the first vehicle 130 detects that the signal strength of the mobile communication network is lower than a preset value, it is determined that the communication connection with the cloud server is disconnected.

[0077] At step 420, in response to the communication connection state being disconnected, a second vehicle satisfying a first preset condition is obtained.

[0078] In some embodiments, the communication status between the second vehicle and the cloud server is connected. In some embodiments, in response to a disconnected communication connection, a first smart central control unit of the second vehicle that meets a first preset condition can be obtained. In some embodiments, the first smart central control unit may include the smart central control unit of other vehicles (such as the second vehicle) within a preset area or a pre-installed smart central control unit. For example, the first smart central control unit may be the smart central control unit of another shared vehicle within the same preset return area as the smart central control unit of the currently shared vehicle (i.e., the smart central control unit with a disconnected communication connection). As another example, the first smart central control unit may be a smart central control unit fixedly installed within the area where the smart central control unit of the current vehicle (i.e., the smart central control unit with a disconnected communication connection) is located.

[0079] In some embodiments, a second vehicle meeting the first preset condition can be determined by acquiring signal information from short-range communication modules within a preset area. For example, the first determining module 220 can acquire corresponding Bluetooth information by receiving Bluetooth signals broadcast by the smart central control systems of other shared vehicles within the preset area, and based on the acquired Bluetooth information, determine the smart central control system (or vehicle) with the optimal signal strength and a connected communication status with the cloud server as the first smart central control system (or the second vehicle). In some embodiments, the signal information from the short-range communication modules may include Bluetooth signal information, which may include, for example, Bluetooth signal strength, and the communication connection status between the smart central control system (or the second vehicle) and the cloud server.

[0080] For example only, such as Figure 6 As shown, if the communication connection between the intelligent central control unit 601 of the first vehicle 130 and the cloud server is lost, the intelligent central control unit 601 can obtain Bluetooth information broadcast by target intelligent central control units 603, 605, 607, 609, and 611 within a preset area through the Bluetooth communication module. Based on the obtained Bluetooth information, the target intelligent central control unit 603 with the best signal strength and a connected communication status with the cloud server is determined as the first intelligent central control unit. In some embodiments, target intelligent central control units 603, 605, 607, 609, and 611 may include intelligent central control units installed on any device or fixed location within the preset area. For example, the device may include, but is not limited to, a charging pile, a user terminal, or other types of vehicles. For example, target intelligent central control units 603, 605, 607, 609, and 611 may be intelligent central control units of multiple second vehicles 140. In some embodiments, the communication method between the intelligent central control of the first vehicle and the target intelligent central control (e.g., target intelligent central control 603, 605, 607, 609 and 611) may include, but is not limited to, other short-range communication methods, such as WiFi, ZigBee, etc., which are not limited in this specification.

[0081] In some embodiments, the second vehicle (or the first intelligent central control) satisfying the first preset condition can be determined in an ordering manner. For example, the obtained Bluetooth signal information of the target intelligent central control can be arranged in order of signal strength from high to low, and then the communication connection state of the target intelligent central control with the cloud server is determined in order, and the first obtained target intelligent central control maintaining the connection is determined as the first intelligent central control, or the vehicle corresponding to the first intelligent central control is determined as the second vehicle. In some embodiments, the first intelligent central control or the second vehicle can be determined by machine learning or other algorithms, which is not limited in the present specification.

[0082] In step 430, the second vehicle communicates with the cloud server.

[0083] In some embodiments, the first vehicle can send the first target information to the cloud server through the second vehicle. For example, the intelligent central control of the first vehicle (i.e. the intelligent central control with communication connection disconnected) can send the first target information to the first intelligent central control of the second vehicle through the short-distance communication module, so that the second vehicle sends the first target information to the cloud server. In some embodiments, the first target information can include vehicle authentication information, vehicle state information, etc. In some embodiments, when the vehicle authentication information of the first vehicle is authenticated, the first vehicle can establish a connection with the second vehicle through the short-distance communication module, for example, the intelligent central control of the first vehicle successfully establishes a communication connection with the first intelligent central control of the second vehicle.

[0084] In some embodiments, the vehicle authentication information can reflect information such as the identity of the vehicle. In some embodiments, the vehicle authentication information can include a vehicle serial number, a data number, a key, an authorization number, an authorization time, an authorization validity period, or the like, or any combination thereof. In some embodiments, the cloud server can determine whether the vehicle (e.g., the first vehicle) is legal according to the vehicle identity included in the vehicle authentication information by querying, etc. For example, the server 110 can determine whether the first vehicle is legal, i.e., whether it is a vehicle normally entered into the database, by matching the vehicle authentication information of the first vehicle with the vehicle information stored in the database. In some embodiments, the cloud server can determine whether the vehicle is legal based on a preset algorithm according to the vehicle identity and other information included in the vehicle authentication information. In some embodiments, the cloud server can obtain information such as the service type, service validity period, vehicle age, and vehicle state of a legal vehicle based on the information stored in the database. In some embodiments, the cloud server can authorize the second vehicle to establish a communication connection with the first vehicle through the short-range communication module in response to determining that the first vehicle is legal based on the vehicle authentication information of the first vehicle, e.g., authorize the first smart center of the second vehicle to establish a communication connection with the smart center of the first vehicle or perform other corresponding operations. In some embodiments, the cloud server can refuse the connection between the second vehicle and the first vehicle in response to the first vehicle being illegal.

[0085] In some embodiments, the smart center of the first vehicle (i.e., the smart center whose communication connection is disconnected) can send vehicle authentication information and vehicle state information such as the lock state, positioning information, etc. to the cloud server through the first smart center of the second vehicle. When the vehicle authentication information of the first vehicle is authenticated, the first vehicle establishes a connection with the second vehicle, e.g., the first vehicle smart center successfully establishes a communication connection with the first smart center of the second vehicle, and the cloud server can obtain the current state of the first vehicle through the second vehicle, so that corresponding operation instructions can be issued for the current state. For example, when the first vehicle is in the unlocked state, the cloud server can issue a lock instruction to the first vehicle through the second vehicle, or obtain the current position of the first vehicle for billing, etc. By sending the vehicle authentication information and the vehicle state information at the same time, the cloud server can obtain the state information of the first vehicle when the vehicle authentication information fails to pass the authentication due to a matching failure, etc., so as to update the related information of the first vehicle in the database.

[0086] In some embodiments, after the smart center of the first vehicle (e.g., the first vehicle 130) (i.e., the smart center with the communication connection disconnected) successfully establishes a communication connection with the first smart center of the second vehicle, the first smart center of the second vehicle can transmit vehicle information to the cloud server (e.g., the server 110) and receive second target information issued by the cloud server. In some embodiments, the second target information can include vehicle operation instructions related to the first vehicle, etc. For example, the smart center of the first vehicle can send vehicle status information to the first smart center of the second vehicle at a fixed time or in real time, so as to send the first vehicle status information to the cloud server through the first smart center. In some embodiments, the smart center of the first vehicle can send vehicle status information to the cloud server through the first smart center of the second vehicle when the vehicle status changes, for example, send the lock / unlock status information when the lock / unlock status changes, and send the positioning information when the position changes.

[0087] In some embodiments, when the cloud server needs to issue data to the first vehicle, it can transmit the data with the first vehicle identifier to the second vehicle through the marking table, and the smart center of the first vehicle can receive the cloud server issued data forwarded by the first smart center of the second vehicle through Bluetooth or the like. In some embodiments, the cloud server can send the lock / unlock instructions to the smart center of the first vehicle through the first smart center of the second vehicle after receiving the user request, for example, send the lock instruction after receiving the user's vehicle request, and send the lock instruction after receiving the user's return request. In some embodiments, the cloud server can send the lock vehicle instruction or obtain the current position information of the first vehicle to the smart center of the first vehicle through the first smart center of the second vehicle when detecting that the first vehicle has an abnormality, for example, illegal use, not in the legal parking area, etc.

[0088] Step 440, obtaining the motion state of the vehicle.

[0089] In some embodiments, the motion state of the vehicle can be obtained through the vehicle sensor. In some embodiments, the motion state of the vehicle can be obtained through the positioning device. In some embodiments, the motion state of the vehicle can be obtained according to the position change of the vehicle within a preset time period, for example, static or moving, speed, acceleration, etc.

[0090] Step 450, in response to the movement of the vehicle, obtaining a third vehicle satisfying a second preset condition.

[0091] The vehicle can move due to use or movement of the user. For example, for a shared bicycle, the vehicle can move due to riding of the user, maintenance of the maintenance personnel, illegal movement of the pedestrian, etc. In some embodiments, when the vehicle moves, the distance between the vehicle and the first smart center / second vehicle changes, which can cause the network connection between the vehicle smart center and the first smart center / second vehicle to weaken, affecting the communication between the first vehicle and the cloud server.

[0092] In some embodiments, a second smart center satisfying a second preset condition can be obtained in response to the movement of the vehicle, where the second smart center is a smart center of a third vehicle. In some embodiments, the second preset condition can include that the difference between the signal strength of the short-distance communication module of the third vehicle (e.g., the second smart center of the third vehicle) and the signal strength of the short-distance communication module of the second vehicle (e.g., the first smart center of the second vehicle) is greater than a preset difference value. In some embodiments, the preset difference value can include but is not limited to 3, 5, 7, etc., which is not limited in the present specification. In some embodiments, the preset difference value can be determined based on the distance between the first smart center and the second smart center (or the second vehicle and the third vehicle). For example, the preset difference value can be a value greater than the average distance between the first smart center and the second smart center. In some embodiments, the second preset condition can include that the signal strength of the short-distance communication module of the third vehicle is greater than the signal strength of the short-distance communication module of the second vehicle.

[0093] In some embodiments, the second preset condition can include that the signal strength (e.g., Bluetooth signal strength) of the short-distance communication module of the third vehicle (e.g., the second smart center of the third vehicle) is greater than a preset strength threshold. In some embodiments, the preset strength threshold can include an initial value and a dynamic value, and the preset strength threshold can be dynamically switched between the initial value and the dynamic value according to the connection status of the vehicle smart center. For example only, after the vehicle smart center A and the first smart center B establish a communication connection, when the vehicle moves, the vehicle smart center A can establish a communication connection with the second smart center C based on the initial value (e.g., 10) of the preset strength threshold and the Bluetooth signal strength greater than the initial value; at this time, in order to prevent the vehicle smart center A from switching between the first smart center B and the second smart center C during the movement of the vehicle, the preset strength threshold can be adjusted to a dynamic value (e.g., 15), in which case the vehicle smart center A will only disconnect the connection with the second smart center C when the Bluetooth signal strength of the first smart center B is greater than the dynamic value, and then establish a connection with the first smart center B again, and the preset strength threshold will return to the initial value. In some embodiments, the dynamic value can be adjusted in real time according to the distance between the first smart center and the second smart center. For example, the dynamic value can be obtained by adding or subtracting a corresponding value from the initial value based on the distance between the first smart center and the second smart center.

[0094] In some embodiments, the vehicle intelligent center can determine whether the vehicle moves relative to the first intelligent center according to whether the connection signal strength with the first intelligent center changes. For example, the vehicle intelligent center can acquire the second intelligent center satisfying the second preset condition when the connection signal strength with the first intelligent center decreases or is lower than a threshold. In some embodiments, the second intelligent center satisfying the first preset condition or the second preset condition can be acquired in response to the disconnection of the first intelligent center from the cloud server, so that the third vehicle corresponding to the second intelligent center is acquired.

[0095] In some embodiments, the first vehicle can disconnect from the second vehicle and connect to the third vehicle through the short-distance communication module, such as the intelligent center of the first vehicle can establish a communication connection with the second intelligent center and disconnect from the first intelligent center. By acquiring the third vehicle (such as the second intelligent center of the third vehicle) satisfying the second preset condition and establishing a communication connection between the first vehicle and the third vehicle, the first vehicle intelligent center can help maintain data communication between the first vehicle intelligent center and the cloud server. In some embodiments, the first intelligent center and the second intelligent center can be the same or different types of intelligent centers. For example, if the communication connection between the intelligent center of the first vehicle 130 and the cloud server is disconnected, the first intelligent center / second intelligent center can be the intelligent center of the second vehicle 140 in the area where the first vehicle 130 is located.

[0096] In step 460, the third vehicle communicates with the cloud server.

[0097] In some embodiments, the intelligent center of the first vehicle can establish a communication connection with the second intelligent center of the third vehicle by sending authentication information to the second intelligent center. In some embodiments, the first vehicle intelligent center can directly establish a communication connection with the second intelligent center. In some embodiments, the first vehicle intelligent center can send first target information, such as vehicle information, to the cloud server through the second intelligent center of the third vehicle and receive second target information, such as operation instructions related to the first vehicle, sent by the cloud server.

[0098] The vehicle communication method provided in the embodiment can use other vehicles in normal communication with the cloud server to communicate data with the cloud server when the vehicle is disconnected from the cloud server, establish a communication connection with the cloud server without the aid of additional equipment, save resources and reduce costs, and at the same time overcome the problem of unavailable network connection caused by blockage of the mobile communication network, insufficient network signal strength, and the like, and guarantee normal service of the vehicle. In addition, in the embodiment, the second intelligent center with a more optimal signal strength is determined during movement of the vehicle based on the preset strength threshold that can be dynamically adjusted, which ensures communication connection between the vehicle and the cloud server, prevents frequent switching between intelligent centers, and guarantees stability of the network connection.

[0099] It should be noted that the description regarding flow 400 above is merely for example and illustration, and does not limit the scope of the present specification. Various modifications and changes can be made to flow 400 under the guidance of the present specification by those skilled in the art. However, these modifications and changes still fall within the scope of the present specification.

[0100] Figure 5 is an exemplary flowchart of a vehicle communication method according to some other embodiments of the present specification.

[0101] In some embodiments, flow 500 can be performed by a cloud server (e.g., server 110 as shown). For example, flow 500 can be stored in a storage device in the form of a program or instructions, for example, storage device 150, when the processor in server 110 executes the program or instructions, flow 500 can be implemented. In some embodiments, flow 500 can be performed by vehicle communication system 300. In some embodiments, flow 500 can utilize one or more additional operations not described below, and / or be completed without one or more operations discussed below. In addition, the order of the operations as shown is not limiting. Figure 1 Figure 5

[0102] At step 510, first target information sent by a second vehicle is received, the first target information including vehicle authentication information of a first vehicle. Wherein, the communication connection state of the first vehicle with the cloud server is disconnected, and the communication state of the second vehicle with the cloud server is connected. In some embodiments, step 510 can be performed by server 110 or second acquisition module 310.

[0103] In some embodiments, the server can acquire the vehicle authentication information of the first vehicle through the first intelligent central control of the second vehicle in response to a service request of a user, for example, a car rental request or a car return request. In some embodiments, the server can acquire the vehicle authentication information of the first vehicle through the first intelligent central control of the second vehicle in response to the disconnection of the communication connection between the first intelligent central control and the server. In some embodiments, the server can acquire the vehicle authentication information sent by the first intelligent central control in response to the data transmission request of the first intelligent central control.

[0104] In some embodiments, the first intelligent central control can be another intelligent central control different from the intelligent central control of the first vehicle. In some embodiments, the authentication information can reflect the identity information of the vehicle. More about the first intelligent central control and the vehicle authentication information can be referred to the relevant description in the present specification, which will not be repeated here. Figure 4

[0105] ​​​At step 520, it is determined whether the first vehicle is legal based on the vehicle authentication information. In some embodiments, step 520 can be performed by server 110 or second determination module 320 (e.g., judgment unit 323).

[0106] In some embodiments, the server can determine whether the identity of the first vehicle is legal by querying based on the vehicle authentication information of the first vehicle. For example, server 110 can determine whether the first vehicle is legal, i.e., whether it is a vehicle that is normally recorded in the database, by matching the vehicle authentication information of the first vehicle with the vehicle information stored in storage device 150. Details of determining whether a vehicle is legal based on vehicle authentication information can be found in the description of the present specification, and will not be described here. Figure 4

[0107] At step 530, the second vehicle is authorized to establish a communication connection with the first vehicle in response to the first vehicle being legal. In some embodiments, step 530 can be performed by server 110 or second determination module 320 (e.g., authorization unit 325).

[0108] In some embodiments, after determining that the first vehicle is legal, the server can authorize the first intelligent central control of the second vehicle to establish a communication connection with the intelligent central control of the first vehicle by sending an execution instruction containing the vehicle authentication result to the first intelligent central control. In some embodiments, the execution instruction can include the identification information of the current vehicle. After receiving the execution instruction of the server to allow the connection, the first intelligent central control can establish a communication connection with the intelligent central control of the first vehicle by short-range communication, such as Bluetooth connection, WiFi connection, etc.

[0109] In some embodiments, after the server authorizes the first intelligent central control to establish a communication connection with the intelligent central control of the first vehicle or determines that the first vehicle is legal, the communication connection information of the first vehicle in the database can be updated. For example, server 110 can mark the communication mode of the first vehicle with the server as being attached to the first intelligent central control of the second vehicle, and add the marking information to the vehicle marking table.

[0110] At step 540, second target information is sent to the first vehicle by the second vehicle based on the vehicle marking table. In some embodiments, step 540 can be performed by server 110 or second communication module 330.

[0111] ​In some embodiments, the server can obtain the attachment relationship between the intelligent central control of the vehicle and the first intelligent central control of the second vehicle by querying a vehicle annotation table, so as to issue second target information, such as an operation instruction related to the first vehicle, to the first intelligent central control of the second vehicle through the first intelligent central control. In some embodiments, the server can issue an operation instruction to the intelligent central control of the first vehicle through the first intelligent central control in response to a service request of a user. For example, the server 110 can send an unlocking instruction to the intelligent central control of the first vehicle through the first intelligent central control in response to a vehicle use request of a user. In some embodiments, the server can issue an operation instruction to the intelligent central control of the first vehicle through the first intelligent central control in response to the real-time state of the vehicle. For example, the server 110 can issue a locking instruction to the intelligent central control of the first vehicle through the first intelligent central control in response to the state of abnormal movement of the first vehicle. In some embodiments, the server can issue an operation instruction to the intelligent central control of the first vehicle through the first intelligent central control at a fixed time or periodically, for example, send a location acquisition instruction at a fixed time.

[0112] In some embodiments, the server can obtain other intelligent central controls around the vehicle when the vehicle moves, and issue an operation instruction to the first vehicle through the other intelligent central controls or a shared vehicle. For example, the server can obtain vehicle authentication information of the first vehicle through the second intelligent central control of the third vehicle, and issue an operation instruction to the intelligent central control of the first vehicle through the second intelligent central control.

[0113] It can be understood that the above embodiments are only examples and are not limiting to the present application. Those skilled in the art can make various modifications and changes to the above embodiments and related descriptions under the guidance of the present specification. Figure 5 However, these modifications and changes are still within the scope of the present specification.

[0114] Figure 7 is an exemplary schematic diagram of a vehicle communication method according to some embodiments of the present specification.

[0115] As shown in Figure 7 , after the connection between the intelligent central control of the first vehicle and the cloud server is disconnected, the first / second intelligent central control that meets the preset condition can communicate with the cloud server.

[0116] In a specific embodiment, after the smart center of the first vehicle 130 determines that the connection between the smart center and the cloud server is disconnected by sending a heartbeat data packet to the server 110, the smart center can obtain the Bluetooth information of other smart centers around the current location through the Bluetooth module of the first vehicle 130, determine that the smart center of the second vehicle 140 with the optimal signal strength and the communication connection state of the server 110 as connected is the first smart center based on the Bluetooth information, and then send the vehicle authentication information to the first smart center. The first smart center forwards the authentication information to the server 110, and the server 110 authorizes the first smart center to establish a Bluetooth connection with the first vehicle smart center after determining that the first vehicle is legal according to the authentication information. After the first vehicle smart center successfully establishes a Bluetooth connection with the first smart center, the first vehicle smart center can send the vehicle positioning location, lock state, battery capacity and other information to the server 110 through the first smart center. The server 110 can issue operation instructions such as opening and closing the lock to the first vehicle smart center through the first smart center.

[0117] In some embodiments, when the first vehicle moves, the first vehicle smart center can disconnect the connection with the first smart center and establish a connection with the second smart center that meets the second preset condition, and communicate with the cloud server through the second smart center.
