[0036] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0038] With the rapid advancement of science and technology and the booming economy, smart cars are gradually becoming popular, and more and more users use smart cars as a means of transportation. Among them, smart cars can include vehicles with two power systems: electric and fuel.

[0039] However, with the increasing number of vehicles and the complex parking environment, users will inevitably forget the specific parking location of their vehicles, making it difficult for users to find their vehicles.

[0040] In the related art, the vehicle positioning can be achieved by communicating with the Bluetooth device in the vehicle. Alternatively, in the related art, the vehicle positioning can be achieved by connecting the vehicle to the remote service platform through the Internet using the Telematics Service Provider (TSP). However, in environments such as underground parking lots, the network signal is poor, so the vehicle positioning cannot be achieved through TSP. The positioning of the vehicle through the Bluetooth device is limited by the signal transmission distance of the Bluetooth signal. When the user is far away from the vehicle, the vehicle positioning cannot be achieved.

[0041] In order to solve the problems in the prior art, the embodiments of the present application provide a vehicle positioning method, device, vehicle and computer storage medium. The vehicle positioning method provided by the embodiments of the present application is first introduced below.

[0042] Figure 1 FIG. 1 is a flow chart of a vehicle positioning method provided by an embodiment of the present application. Figure 1 As shown, the vehicle positioning method includes the following steps:

[0043] S110: After detecting a vehicle locking signal, obtaining a first communication signal corresponding to a first signal source along the way.

[0044] Exemplarily, after detecting the vehicle locking signal, the mobile smart device may move with the user and receive a first communication signal sent by a first signal source along the way.

[0045] Exemplarily, the first signal source may interact with the mobile smart device in a broadcasting manner, so that the mobile smart device can perceive the first signal source.

[0046] In one example, the first signal source may be a Bluetooth device deployed in the vehicle; or, the first signal source may be a local area network transmitting device deployed in the vehicle, such as Wireless Fidelity (WiFi).

[0047] Exemplarily, the first signal source includes one or more.

[0048] It is understandable that the first signal source in the embodiment of the present application may be a signal source that has not established a communication connection with the mobile smart device, that is, using a signal source that has not established a communication connection can avoid complex operations such as protocol handshake and data transmission between the mobile smart device and the signal source, so that the first communication signal broadcast by the first signal source can be obtained more conveniently and quickly. Furthermore, some signal sources cannot establish a communication connection due to security policies, network restrictions, etc., and in the embodiment of the present application, the mobile smart device does not establish a communication connection with each signal source, but only receives the signal broadcast by the signal source, which can ensure that the signal resources in the surrounding environment are fully utilized and increase the diversity of signal sources available for positioning.

[0049] S120. Construct a positioning detection auxiliary record according to the first communication signal, wherein the positioning detection auxiliary record includes first attribute information corresponding to the first communication signal, and the first attribute information at least includes a first signal source identifier.

[0050] Exemplarily, the first communication signal includes first attribute information, wherein the first attribute information includes at least a first signal source identifier. The first signal source identifier can be used to characterize the first signal source.

[0051] In one example, the signal source identifier may include a name of the signal source and / or a physical address (Media Access Control Address, MAC) of the signal source.

[0052] Exemplarily, a positioning detection auxiliary record is constructed by using the first attribute information corresponding to the first signal source, wherein the positioning detection auxiliary record at least includes a first signal source identifier corresponding to the first signal source. Furthermore, the first signal source identifier used to represent the first signal source is unique and can uniquely represent the corresponding first signal source in the positioning detection auxiliary record.

[0053] Exemplarily, the positioning detection auxiliary record can be constructed according to the first communication signal in a preset time period. The preset time period can be preset by relevant visual technicians; or the preset time period can be set by the user according to needs and environment.

[0054] In one example, the user can set the preset time period to 10 minutes, that is, after detecting the vehicle locking signal, the positioning detection auxiliary signal can be constructed through the first communication signal of the first signal source passing within 10 minutes.

[0055] In some optional embodiments, the first attribute information also includes: at least one of the signal strength, signal reception time, signal strongest time and signal latest reception time corresponding to the first communication signal.

[0056] Exemplarily, the first attribute information may include the first signal source identifier and at least one of the signal strength, signal reception time, signal strongest time, and signal latest reception time corresponding to the first communication signal. In one example, the first attribute information may include the first signal source identifier and the signal strength. In another example, the first attribute information may include the first signal source identifier and the signal latest reception time. In another example, the signal reception time may be the time when the signal is first received, and the signal strength may be the strongest signal strength corresponding to the signal with the strongest signal strength. The first attribute information may be stored according to the five dimensions of the first signal source identifier, the strongest signal strength of the first signal source identifier, the first signal reception time, the strongest signal time, and the latest signal reception time.

[0057] Exemplarily, each parameter in the first attribute information may be updated according to the received first communication signal.

[0058] S130. In response to receiving a vehicle search signal, receiving a second communication signal corresponding to a second signal source along the route, and obtaining second attribute information corresponding to the second communication signal, wherein the second attribute information at least includes a second signal source identifier.

[0059] Exemplarily, in the case of receiving a vehicle search signal, the mobile smart device may receive a second information signal sent by a second signal source along the way as the user moves.

[0060] In one example, the first signal source may be a Bluetooth device deployed in the vehicle; or, the first signal source may be a local area network transmitting device deployed in the vehicle.

[0061] Exemplarily, the second communication signal includes second attribute information, wherein the second attribute information includes at least a second signal source identifier, and the second signal source identifier is used to characterize the first signal source.

[0062] In one example, the second signal source identifier may include a name of the signal source and / or a physical address (Media Access Control Address, MAC) of the signal source.

[0063] Exemplarily, the vehicle search signal may indicate that the user needs to search for the vehicle. In one example, the vehicle search signal may be a signal source existing in the detection auxiliary record of the positioning detection, and the Bluetooth key is disconnected from the vehicle; or, it may be a user's vehicle search instruction received in a related vehicle search application.

[0064] S140: Match the second signal source identifier with the first signal source identifier in the positioning detection auxiliary record to obtain a matching result.

[0065] Exemplarily, the second signal source identifier corresponding to the second signal source may be matched according to the first signal source identifier in the positioning detection auxiliary record, and a matching result between the first signal source identifier and the second signal source identifier may be obtained.

[0066] S150. Determine vehicle positioning information based on the first attribute information, the second attribute information and the matching result.

[0067] Exemplarily, the positioning information of the vehicle may be determined based on the first attribute information corresponding to the first signal source, the second attribute information corresponding to the second signal source, and the matching result.

[0068] Exemplarily, after detecting the vehicle lock signal, the first communication signal corresponding to the first signal source of the route can be obtained, and a positioning detection auxiliary record can be constructed based on the first communication signal, wherein the positioning detection auxiliary record includes the first attribute information corresponding to the first communication signal, and the first attribute information at least includes the first signal source identifier. Further, after receiving the vehicle search signal, the second communication signal corresponding to the second signal source of the route can be received, and the second attribute information corresponding to the second communication signal can be obtained, wherein the second attribute information at least includes the second signal source identifier. Then, the vehicle positioning information is determined through the matching result between the second signal source identifier and the first signal source identifier in the positioning detection auxiliary record, the first attribute information, and the second attribute information.

[0069] In an embodiment of the present application, after detecting a user's vehicle locking signal, a first communication signal corresponding to a first signal source along the user's path can be obtained, and a positioning detection auxiliary record can be constructed based on the first communication signal. In the case of detecting a vehicle search signal, the second signal source identifier in the second attribute information corresponding to the second signal source in the positioning detection auxiliary record can be matched with the first signal source identifier in the first attribute information corresponding to the first signal source in the positioning detection auxiliary record to obtain a matching result, and then the vehicle positioning information is determined using the matching result, the first attribute information, and the second attribute information. It can be understood that in an embodiment of the present application, the positioning information of the vehicle can be obtained through the first attribute information of the signal source along the user's walking path and the second attribute information of the currently received signal source, thereby guiding the user to the vehicle to be found.

[0070] In order to construct a positioning detection auxiliary record, as another implementation method of the present application, the present application also provides another implementation method of the vehicle positioning method, please refer to the following embodiments for details.

[0071] Figure 2 A flow chart of a vehicle positioning method provided in another embodiment of the present application is shown.

[0072] like Figure 2 As shown, the vehicle positioning method includes the following steps:

[0073] S210: After detecting the vehicle locking signal, obtaining a first communication signal corresponding to a first signal source along the way.

[0074] S220. Determine whether the first signal source identifier corresponding to the first communication signal already exists in the positioning detection auxiliary record, and whether the latest signal receiving time corresponding to the first signal source identifier in the positioning detection auxiliary record is more than a preset time from the current time; if not, execute S240; if yes, execute S230.

[0075] S230: Ignore the first communication signal.

[0076] S240. Construct a positioning detection auxiliary record according to the first communication signal, wherein the positioning detection auxiliary record includes first attribute information corresponding to the first communication signal, and the first attribute information at least includes a first signal source identifier.

[0077] S250. In response to receiving a vehicle search signal, receiving a second communication signal corresponding to a second signal source along the route, and obtaining second attribute information corresponding to the second communication signal, wherein the second attribute information at least includes a second signal source identifier.

[0078] S260: Match the second signal source identifier with the first signal source identifier in the positioning detection auxiliary record to obtain a matching result.

[0079] S270. Determine vehicle positioning information based on the first attribute information, the second attribute information and the matching result.

[0080] In some embodiments, step S210 is consistent with step S110, and steps S240-S270 are consistent with steps S120-S150, which will not be described in detail here.

[0081] In some embodiments, in S220, after receiving the first communication signal, it can be determined whether the first signal source identifier corresponding to the first communication signal is already located in the positioning detection auxiliary record, and the latest signal reception time corresponding to the first signal source identifier in the positioning detection auxiliary record is more than a preset time distance from the current time.

[0082] Further, in the case where it is determined that the first signal source identifier corresponding to the first communication signal is already located in the positioning detection auxiliary record, and the latest signal reception time corresponding to the first signal source identifier in the positioning detection auxiliary record exceeds a preset time length from the current time, step S230 can be executed to ignore the first communication signal, that is, the first communication signal is used to construct the positioning detection auxiliary record. In the case where it is determined that the first signal source identifier corresponding to the first communication signal is not located in the positioning detection auxiliary record, or the first signal source identifier corresponding to the first communication signal is already located in the positioning detection auxiliary record, but the latest signal reception time corresponding to the first signal source identifier in the positioning detection auxiliary record does not exceed a preset time length from the current time, step S240 can be executed, that is, constructing a positioning detection auxiliary record based on the first communication signal.

[0083] In one example, when the first signal source is a Bluetooth device, the Bluetooth device can send Bluetooth signals at a frequency of milliseconds. At the same time, the mobile smart device can receive Bluetooth signals continuously sent by the Bluetooth device within a certain range. If the Bluetooth signal sent by the Bluetooth device is not received for more than 10 seconds, it may not be recorded in the positioning detection auxiliary record.

[0084] In an embodiment of the present application, when the first communication signal corresponding to the first signal source is not received within a preset time period, the use of the first communication signal to construct a positioning detection auxiliary record is stopped. This can avoid repeatedly establishing records of the first communication signal in the positioning detection auxiliary record, thereby avoiding the problem of inaccurate subsequent vehicle positioning.

[0085] In some optional embodiments, the first attribute information may include the signal strength and signal reception time corresponding to the first signal source identifier, and the second attribute information may further include: the second signal source identifier and the signal strength corresponding to the second signal source identifier.

[0086] Furthermore, in order to achieve vehicle positioning when the first attribute information can include the signal strength and signal reception time corresponding to the first signal source identifier, and the second attribute information can also include the second signal source identifier and the signal strength corresponding to the second signal source identifier, as another implementation method of the present application, the present application also provides another implementation method of the vehicle positioning method, please refer to the following embodiments for details.

[0087] Figure 3 A flow chart of a vehicle positioning method provided in another embodiment of the present application is shown.

[0088] like Figure 3 As shown, the vehicle positioning method includes the following steps:

[0089] S310: After detecting a vehicle locking signal, obtaining a first communication signal corresponding to a first signal source along the way.

[0090] S320. Construct a positioning detection auxiliary record according to the first communication signal, wherein the positioning detection auxiliary record includes first attribute information corresponding to the first communication signal, and the first attribute information includes a first signal source identifier, a signal strength corresponding to the first signal source identifier, and a signal reception time.

[0091] S330, in response to receiving a vehicle search signal, receiving a second communication signal corresponding to a second signal source along the route, and obtaining second attribute information corresponding to the second communication signal, wherein the second attribute information includes a second signal source identifier and a signal strength corresponding to the second signal source identifier.

[0092] S340: Match the second signal source identifier with the first signal source identifier in the positioning detection auxiliary record to obtain a matching result.

[0093] S350. When the matching result indicates that the positioning detection auxiliary record includes a first signal source identifier that is identical to the second signal source identifier, and the signal reception time corresponding to the same first signal source identifier is less than a preset time interval from the vehicle, the same first signal source identifier is used as a reference signal source identifier.

[0094] S360: Determine the starting signal source where the user is currently located based on the signal strength corresponding to the second signal source identifier.

[0095] S370. Determine, according to the signal strength and signal reception time corresponding to each reference signal source identifier in the positioning detection auxiliary record, a target signal source whose signal disappears earlier than the start signal source in the positioning detection auxiliary record.

[0096] S380: Generate vehicle positioning information, where the vehicle positioning information is used to instruct the user to walk from the starting signal source to the target signal source.

[0097] In some embodiments, steps S310 - S340 are consistent with steps S110 - S140 and are not described in detail herein.

[0098] In some embodiments, in S350, when the matching result between the second signal source identifier and the first signal source identifier indicates that the positioning detection auxiliary record includes a first signal source identifier that is identical to the second signal source identifier, and the signal reception time corresponding to the same first signal source identifier is less than a preset time interval from the vehicle time, the same first signal source identifier may be used as a reference signal source identifier.

[0099] Exemplarily, when it is determined that the second signal source identifier is the same as the first signal source identifier in the positioning detection auxiliary record, the signal reception time of the signal source can be determined from the positioning detection auxiliary record. When it is determined that the signal reception time is less than a preset time interval, the signal source can be represented by the range corresponding to the user's current location.

[0100] Exemplarily, the preset time interval may be pre-set by relevant technicians, or the preset time interval may be set by a user according to different environments.

[0101] In one example, when the signal source identification is represented by the signal name, the positioning detection auxiliary record may include signal source A, and the signal receiving time corresponding to signal source A may be t1; signal source B, and the signal receiving time corresponding to signal source B may be t2; and signal source C, and the signal receiving time corresponding to signal source C may be t3. When the second signal source identification is signal source C, it can be determined whether the time difference between t3 and the time when the vehicle locking signal is received is less than a preset time interval. For example, when it is determined that the time difference between t3 and the time when the vehicle locking signal is received is less than 10 minutes, signal source C can be used as a reference signal source identification. It can be understood that the reference signal source may include one or more.

[0102] In some embodiments, in S360, the starting signal source where the user is currently located may be determined based on the signal strength corresponding to the second signal source identifier.

[0103] Exemplarily, the starting signal source where the user is currently located may be determined from the reference signal source identifier according to the signal strength corresponding to the second signal source identifier.

[0104] In one example, a signal with the largest signal strength among the reference signal source identifiers may be used as the starting signal source.

[0105] Exemplarily, the starting signal source is used to indicate the current location of the user.

[0106] In some embodiments, in S370, the target signal source whose signal disappears earlier than the start signal source in the positioning detection auxiliary record can be determined according to the signal strength and signal reception time corresponding to each reference signal source identifier in the positioning detection auxiliary record.

[0107] Exemplarily, the target signal source may be a signal source whose signal disappearance time is earlier than the signal disappearance time corresponding to the start signal source. In addition, the target signal source may be determined by the currently received signal strength, the signal strength corresponding to each reference signal source identifier, and the signal reception time.

[0108] Exemplarily, the target signal source may be any one of the signal sources whose signal disappearance time is earlier than the signal disappearance time of the reference signal source. It is understandable that the target signal source may be adjusted as the user moves.

[0109] In one example, a signal sequence can be constructed according to the signal reception time corresponding to each reference signal source identifier, for example, the signal sequence can be constructed according to the order of the signal reception time. In addition, a signal source whose signal disappearance time is earlier than that of the starting signal source is determined from the signal sequence. Furthermore, the target signal source can be determined by comparing the signal strength corresponding to the starting signal source with the signal strength corresponding to the signal source whose disappearance time is earlier than that of the starting signal source.

[0110] In some embodiments, in S380, vehicle positioning information may be generated according to the target signal source and the reference signal source, wherein the vehicle positioning information is used to instruct the user to walk from the starting signal source to the target signal source.

[0111] Exemplary, combined Figure 4 as well as Figure 5 , the vehicle positioning method is described. Among them, Figure 4 A schematic diagram showing the distribution of vehicles during the process of leaving a vehicle provided by an embodiment of the present application is shown. Figure 5 A schematic diagram of vehicle distribution during a vehicle search process provided by an embodiment of the present application is shown.

[0112] In an example, Figure 4 As shown, after locking the car, the user passes by vehicle 1, vehicle 2 and vehicle 3 in turn, wherein vehicle 1 is equipped with signal source A, vehicle 2 is equipped with signal source B, and vehicle 3 is equipped with signal source C. Moreover, in this process, the positioning detection auxiliary record constructed according to signal source A, signal source B and signal source C may include: the signal source is identified as signal source A, and its corresponding signal disappearance time t1 and strongest signal strength m1; the signal source is identified as signal source B, and its corresponding signal disappearance time t2 and strongest signal strength m2; the signal source is identified as signal source C, and its corresponding signal disappearance time t3 and strongest signal strength m3. Furthermore, as Figure 5 As shown, in the process of searching for a vehicle, when passing by vehicle 3, the user may receive a communication signal sent by signal source C, wherein the communication signal sent by signal source C may include a signal table identifier of signal source C. When it is determined that the signal source identifier of signal source C is included in the positioning detection auxiliary record, the target signal source can be determined according to the signal strength corresponding to the current signal source C. For example, when it is determined that the received signal strength of signal source C is greater than the signal strength m3, signal source B can be used as the target signal source. Alternatively, when the signal strength of signal source C is less than or equal to the signal strength m3, signal source C can be used as the target signal source.

[0113] In the embodiment of the present application, when the matching result indicates that the positioning detection auxiliary record includes the same first signal source identifier as the second signal source identifier, and the signal reception time corresponding to the same first signal source identifier is less than the preset time interval from the vehicle, the same first signal source identifier is used as the reference signal source identifier; and based on the signal strength corresponding to the second signal source identifier, the starting signal source where the user is currently located is determined. Further, according to the signal strength and signal reception time corresponding to each reference signal source identifier in the positioning detection auxiliary record, the target signal source in the positioning detection auxiliary record whose signal disappears earlier than the starting signal source is determined; the vehicle positioning information is generated, so that the user can walk from the starting signal source to the target signal source, ensuring that the user can quickly and easily find the vehicle.

[0114] In order to achieve vehicle positioning when the first attribute information can include the signal strength and signal reception time corresponding to the first signal source identifier, and the second attribute information can also include the second signal source identifier and the signal strength corresponding to the second signal source identifier, as another implementation method of the present application, the present application also provides another implementation method of the vehicle positioning method, please refer to the following embodiments for details.

[0115] Figure 6 A flow chart of a vehicle positioning method provided in another embodiment of the present application is shown.

[0116] like Figure 6 As shown, the vehicle positioning method includes the following steps:

[0117] S610: After detecting a vehicle locking signal, obtaining a first communication signal corresponding to a first signal source along the way.

[0118] S620. Construct a positioning detection auxiliary record according to the first communication signal, wherein the positioning detection auxiliary record includes first attribute information corresponding to the first communication signal, and the first attribute information includes a first signal source identifier, a signal strength corresponding to the first signal source identifier, and a signal reception time.

[0119] S630. In response to receiving a vehicle search signal, a second communication signal corresponding to a second signal source along the receiving path is received, and second attribute information corresponding to the second communication signal is obtained, wherein the second attribute information includes a second signal source identifier and a signal strength corresponding to the second signal source identifier.

[0120] S640: Match the second signal source identifier with the first signal source identifier in the positioning detection auxiliary record to obtain a matching result.

[0121] S650. When the matching result indicates that the positioning detection auxiliary record includes the first signal source identifier that is identical to the second signal source identifier, and the signal strengths corresponding to the identical first signal source identifiers are all less than the preset signal strength threshold, determine whether the signal strength corresponding to the second signal source identifier gradually decreases as the user moves. If so, execute S660. If not, execute S670.

[0122] S660: Generate vehicle positioning information for instructing the user to turn.

[0123] S670: Generate vehicle positioning information for instructing the user to continue moving forward.

[0124] In some embodiments, steps S610-S640 are consistent with steps S310-S340 and are not described in detail herein.

[0125] In some embodiments, in S650, when the matching result indicates that the positioning detection auxiliary record includes a first signal source identifier that is identical to the second signal source identifier, and the signal strengths corresponding to the identical first signal source identifier are all less than a preset signal strength threshold, it can be determined whether the signal strength corresponding to the second signal source identifier gradually decreases as the user moves. In the case where it is determined that the signal strength corresponding to the second signal source identifier gradually decreases as the user moves, S660 can be executed, i.e., vehicle positioning information for instructing the user to turn can be generated. In the case where it is determined that the signal strength corresponding to any one of the second signal source identifiers gradually increases as the user moves, S670 can be executed, i.e., vehicle positioning information for instructing the user to continue moving can be generated.

[0126] In an example, Figure 5 As shown, when the user is near the vehicle 3, the second communication signal sent by the signal source A, the signal source B and the signal source C can be detected, wherein the second communication signal sent by the signal source A, the signal source B and the signal source C contains the corresponding signal strength. When the signal strength corresponding to the signal source A, the signal source B and the signal source C decreases as the user moves, it can be determined that the user's current moving direction is opposite to the position of the vehicle to be found. Therefore, the user can be instructed to turn by generating the vehicle positioning information of the user's turn, thereby ensuring that the user can gradually approach the vehicle to be found. When the signal strength corresponding to any one of the signal sources A, the signal source B and the signal source C increases as the user moves, it can be determined that the user's current moving direction is consistent with the direction of the target vehicle. Therefore, the vehicle positioning information for instructing the user to continue moving forward can be generated to enable the user to continue moving in the current direction.

[0127] In an embodiment of the present application, the positional relationship between the user's moving direction and the vehicle to be found can be determined by using the changing trend of the signal strength of the second communication signal as the user moves, thereby generating corresponding vehicle positioning information to guide the user to find the vehicle to be found more conveniently and quickly.

[0128] In order to achieve vehicle positioning when the first attribute information can include the signal strength and signal reception time corresponding to the first signal source identifier, and the second attribute information can also include the second signal source identifier and the signal strength corresponding to the second signal source identifier, as another implementation method of the present application, the present application also provides another implementation method of the vehicle positioning method, please refer to the following embodiments for details.

[0129] Figure 7 A flow chart of a vehicle positioning method provided in another embodiment of the present application is shown.

[0130] like Figure 7 As shown, the vehicle positioning method includes the following steps:

[0131] S710: After detecting a vehicle locking signal, obtaining a first communication signal corresponding to a first signal source along the way.

[0132] S720. Construct a positioning detection auxiliary record according to the first communication signal, wherein the positioning detection auxiliary record includes first attribute information corresponding to the first communication signal, and the first attribute information includes a first signal source identifier, a signal strength corresponding to the first signal source identifier, and a signal reception time.

[0133] S730. In response to receiving a vehicle search signal, a second communication signal corresponding to a second signal source along the receiving path is received, and second attribute information corresponding to the second communication signal is obtained, wherein the second attribute information includes a second signal source identifier and a signal strength corresponding to the second signal source identifier.

[0134] S740: Match the second signal source identifier with the first signal source identifier in the positioning detection auxiliary record to obtain a matching result.

[0135] S750: When the matching result indicates that the positioning detection auxiliary record includes a first signal source identifier that is the same as the second signal source identifier and also includes a first signal source identifier that is different from the second signal source identifier, generate vehicle positioning information for instructing the user to continue moving forward.

[0136] S760. When the user continues to move forward, if a third communication signal from a third signal source is received, vehicle positioning information is generated to prompt the user to continue moving forward. The third signal source is a signal source recorded in the positioning detection auxiliary record, and the signal disappears earlier than the second signal source.

[0137] S770: When the user continues to move forward, if the third communication signal from the third signal source is not received, generate vehicle positioning information for instructing the user to turn.

[0138] In some embodiments, steps S710-S740 are consistent with steps S310-S340 and are not described in detail herein.

[0139] In some embodiments, in S750, when the matching result indicates that the positioning detection auxiliary record includes a first signal source identifier that is identical to the second signal source identifier and also includes a first signal source identifier that is different from the second signal source identifier, vehicle positioning information is generated to instruct the user to continue moving forward.

[0140] Exemplarily, when it is determined that there is a first signal source identifier that is consistent with the second signal source identifier corresponding to the second communication signal in the positioning detection auxiliary record, and the positioning detection auxiliary record also includes other signal source identifiers, vehicle positioning information can be generated to prompt the user to continue moving forward, thereby assisting the user to move forward.

[0141] Exemplarily, the first signal source identifier different from the second signal source identifier may be a signal source whose signal disappears earlier than that of the second signal source.

[0142] In some embodiments, in S760, when the user continues to move forward, if a third communication signal from a third signal source is received, vehicle positioning information for prompting the user to continue moving forward is generated. The third signal source is a signal source recorded in the positioning detection auxiliary record, and the signal disappears earlier than the second signal source.

[0143] Exemplarily, within the target time period when the user continues to move forward, if a third communication signal from a third signal source is received, vehicle positioning information is generated to prompt the user to continue to move forward. The third signal source is a signal source recorded in the positioning detection auxiliary record, and the signal disappears earlier than the second signal source.

[0144] In some embodiments, in S770, when the user continues to move forward, if the third communication signal from the third signal source is not received, vehicle positioning information for instructing the user to turn is generated.

[0145] Exemplarily, during the target time period in which the user continues to move forward, if the third communication signal from the third signal source is not received, vehicle positioning information for instructing the user to turn is generated.

[0146] In an example, Figure 5As shown, if the distance between vehicle 3 and vehicle 1 and vehicle 2 is far, or there are other vehicles between vehicle 3 and vehicle 1 and vehicle 2, the user is near vehicle 3 and can only receive the communication information sent by signal source C in vehicle 3. At this time, the user can be instructed to continue moving forward and receive the communication signal in real time. In the target time period for the user to move forward, which can be 20 seconds, for example, if the second communication signal sent by signal source A or signal source B is received, the user can be prompted to continue moving forward; if the second communication signal sent by signal source A or signal source B is still not detected after 20 seconds, the user can be prompted to turn, or the user can be prompted to be closer to the vehicle to be found 20 seconds ago.

[0147] In an embodiment of the present application, when the second signal source identifier in the second communication signal does not completely match the first signal source representation in the positioning detection auxiliary record, the user can be prompted to move first, and then the user's movement direction can be judged to be correct based on the signal source detected during the movement. This can improve the universality of the vehicle positioning method and guide the user to find the vehicle to be found.

[0148] Furthermore, in order to achieve vehicle positioning when the first attribute information can include the signal strength and signal reception time corresponding to the first signal source identifier, and the second attribute information can also include the second signal source identifier and the signal strength corresponding to the second signal source identifier, as another implementation method of the present application, the present application also provides another implementation method of the vehicle positioning method, please refer to the following embodiments for details.

[0149] Figure 8 A flow chart of a vehicle positioning method provided in another embodiment of the present application is shown.

[0150] like Figure 8 As shown, the vehicle positioning method includes the following steps:

[0151] S810: After detecting a vehicle locking signal, obtaining a first communication signal corresponding to a first signal source along the way.

[0152] S820. Construct a positioning detection auxiliary record according to the first communication signal, wherein the positioning detection auxiliary record includes first attribute information corresponding to the first communication signal, and the first attribute information at least includes a first signal source identifier.

[0153] S830. In response to receiving a vehicle search signal, receiving a second communication signal corresponding to a second signal source along the route, and obtaining second attribute information corresponding to the second communication signal, wherein the second attribute information at least includes a second signal source identifier.

[0154] S840: Match the second signal source identifier with the first signal source identifier in the positioning detection auxiliary record to obtain a matching result.

[0155] Exemplarily, steps S810 - S840 are consistent with steps S110 - S140 , and are not described in detail here.

[0156] S850: When the matching result indicates that the positioning detection auxiliary record does not include the first signal source identifier that is identical to the second signal source identifier, generate vehicle positioning information indicating that the vehicle position is far from the user's current position.

[0157] Exemplarily, when the matching result indicates that the positioning detection auxiliary record does not include the first signal source identifier that is identical to the second signal source identifier, vehicle positioning information indicating that the vehicle position is far away from the user's current position may be generated.

[0158] In one example, when the second signal source identifier corresponding to the second communication signal is different from the first signal source identifiers in the positioning detection auxiliary record, it can be determined that the user's current position is far away from the position of the vehicle to be found, and vehicle positioning information can be generated to indicate that the vehicle position is far away from the user's current position.

[0159] In one example, the matching result indicates that the positioning detection auxiliary record includes a first signal source identifier that is identical to the second signal source identifier, and when the signal reception time corresponding to the identical first signal source identifier is greater than or equal to a preset time interval, it can be determined that the user's current position is far from the position of the vehicle to be found, and vehicle positioning information can be generated to indicate that the vehicle position is far away from the user's current position.

[0160] In an embodiment of the present application, when it is determined that the user's current location is far away from the location of the vehicle to be found, vehicle positioning information can be generated to indicate that the vehicle location is far away from the user's current location, thereby avoiding the user from starting to search for the vehicle at a location far away from the vehicle to be found, thereby improving the user's vehicle search speed.

[0161] In some optional embodiments, when it is determined that the second signal source identifier includes a vehicle signal source identifier corresponding to the vehicle, the signal strength corresponding to the vehicle signal source is obtained; and the vehicle positioning information is determined based on the signal strength. It is understandable that the positioning information corresponding to the vehicle can be determined based on the signal strength corresponding to the vehicle signal source, so that the vehicle can be positioned at a short distance, providing convenience for users to find the vehicle.

[0162] In some optional embodiments, the first attribute information includes a first signal source identifier and a signal strength corresponding to the first signal source identifier; the second attribute information includes a second signal source identifier and a signal strength corresponding to the second signal source identifier. In one example, the vehicle positioning information can be determined by matching the signal strengths corresponding to multiple second signal source identifiers with the strengths corresponding to multiple first signal source identifiers.
