Description

Technical Field

[0001] The present application relates to the fields of intelligent transportation, intelligent driving and map technology, and in particular to a method for generating communication capability information, a method for using the information and a device for the same. Background Art

[0002] In autonomous or assisted driving, road environment perception is paramount. Autonomous or assisted vehicles can use high-precision maps as fundamental driving reference information. Unlike traditional navigation maps, HD maps contain more precise information layers than standard navigation maps, providing more comprehensive road information. HD map information layers are divided into static and dynamic layers. Static layers display static information such as specific lane models, while dynamic layers display dynamic information such as traffic light status and road conditions.

[0003] The communication information provided by roadside equipment can be used as reference information for intelligent driving decision-making and control. Therefore, the communication capability of roadside equipment is an important factor affecting the safety of intelligent driving.

[0004] When roadside equipment leaves the factory, manufacturers typically indicate the communication range of the equipment. However, because the equipment's communication range is dependent on factors such as road structure and building obstruction, there can be discrepancies between the equipment's actual communication range and the factory-designed range. Due to the large number of roadside equipment deployed and the complex installation scenarios, conducting individual communication range tests at each installation location is labor-intensive and impractical. Therefore, determining the actual communication range of roadside equipment quickly and accurately is a pressing issue. Summary of the Invention

[0005] In view of this, a communication capability information generation method, a use method and a device are proposed, which can conveniently and accurately obtain the communication range of roadside equipment.

[0110] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0111] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0112] In addition, numerous specific details are provided in the detailed description below to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0113] Figure 1 A schematic diagram showing an application scenario involved in an embodiment of the present application is shown. Figure 1 As shown, there are vehicles traveling on the road and pedestrians walking on the roadside. Roadside equipment is installed on the roadside or above the road. The roadside equipment can sense the surrounding traffic participants (for example, vehicles, pedestrians or non-motor vehicles, etc.) through its sensor device (for example, microwave radar, millimeter wave radar or camera, etc.). After the roadside equipment establishes a communication connection with the surrounding terminal devices, the sensed information can be sent as communication information to the surrounding terminal devices, thereby providing a reference for the intelligent driving decision-making and control of the terminal devices. The terminal devices involved in the embodiments of the present application include but are not limited to vehicle-side devices that can be installed in vehicles and portable mobile terminals. Among them, the mobile terminal can be a smart phone, a tablet computer, a wearable electronic device (such as a smart bracelet, a smart watch or smart glasses, etc.), etc.

[0114] In an embodiment of the present application, a terminal device is configured with a positioning module, such as a Global Positioning System (GPS) and a BeiDou Navigation System (BDS), which can be used to collect the location information and corresponding time information of the terminal device. In one example, the location information can be absolute coordinates (i.e., longitude and latitude coordinates) or relative coordinates. The time information can be a Coordinated Universal Time (UTC) timestamp.

[0115] In an embodiment of the present application, the terminal device is further configured with a communication module for communicating with a roadside device. In one example, the communication module may be an on-board communication unit (OBU). In another example, the communication module may be a wireless communication module in a mobile terminal. The operating status information of the communication module may be used to indicate the operating status of the communication module. In one example, the operating status information of the communication module may be a normal operating state, an abnormal operating state, or an unactivated state. The normal operating state indicates that the communication module has been activated and can operate normally (i.e., a communication connection can be established with the roadside device), the abnormal operating state indicates that the communication module has been activated but cannot operate normally (i.e., a communication connection cannot be established with the roadside device), and the unactivated state indicates that the communication module is not activated. It is understood that when the communication module of the terminal device is in an abnormal operating state or an unactivated state, even if the terminal device is within the communication range of a roadside device, the terminal device cannot establish a communication connection with the roadside device. When the communication module of the terminal device is in a normal operating state, if the terminal device is within the communication range of a roadside device, the terminal device can establish a communication connection with the roadside device.

[0116] In an embodiment of the present application, the roadside device is configured with a communication module for communicating with the terminal device. In one example, the communication module in the roadside device may be a roadside communication unit (RSU). A communication connection may be established between the vehicle-side device and the roadside device through a vehicle-to-X (V2X) technology such as a dedicated short-range communication (DSRC) technology. Specifically, a V2X communication connection may be established between the vehicle-side device and the roadside device through an on-board unit and a roadside unit. In another example, the communication module in the roadside device may be a wireless communication module. A communication connection may be established between the mobile terminal and the roadside device through a wireless communication technology such as a wireless fidelity (Wi-Fi) technology. Specifically, a wireless communication connection may be established between the mobile terminal and the roadside device through a wireless communication module.

[0117] It should be noted that the above is only an exemplary description of the terminal device, positioning module and communication module involved in the embodiments of the present application and does not constitute a specific limitation. The terminal device involved in the embodiments of the present application can also be other devices that can collect their own location information and can communicate with roadside equipment.

[0118] like Figure 1As shown, the communication range of the roadside device is limited. When the distance between the terminal device and the roadside device is far or there is an obstruction between the terminal device and the roadside device (for example, separated by a building), the roadside device may not be able to establish a communication connection with the terminal device, or the communication effect with the terminal device is poor (for example, poor stability or low signal strength, etc.). When the distance between the terminal device and the roadside device is close and there is no obstruction between the terminal device and the roadside device, the roadside device and the terminal device can establish a communication connection with better communication effect. When the roadside device can establish a communication connection with a terminal device in an area with better communication effect, it indicates that the area belongs to the communication range of the roadside device. When the roadside device cannot establish a communication connection with a terminal device in an area with better communication effect, it indicates that the area is beyond the communication range of the roadside device. Based on the communication range of the roadside device, it can be determined in which areas the information collected by the roadside device is more comprehensive and more reliable, and in which areas the information collected is missing and less reliable. The communication capability information generation method provided in the embodiment of the present application can conveniently and accurately obtain the communication range of the roadside device.

[0119] Figure 2 FIG. 1 is a flow chart showing a method for generating communication capability information provided by an embodiment of the present application. Figure 2 As shown, the method may include:

[0120] Step S201: Acquire first communication status indication information.

[0121] Step S202: Determine a first distribution of the plurality of location points around the first roadside equipment according to the first communication status indication information.

[0122] Step S203: Generate first communication capability information of the first roadside device according to the first distribution situation.

[0123] The first roadside device represents a roadside device for which communication capability determination is required. The first roadside device may be any roadside device. The first communication capability information may represent communication capability information of the first roadside device. The first communication capability information may be used to indicate the communication capability of the first roadside device, such as areas in which the first roadside device can communicate and areas in which the first roadside device cannot communicate.

[0124] The first communication status indication information can be used to indicate that multiple terminal devices have established communication connections with the first roadside device at multiple locations. When a terminal device establishes a communication connection with the first roadside device at a location, it indicates that the location is within the communication range of the first roadside device and that the communication capability of the first roadside device is capable of reaching the location. Therefore, based on the distribution of multiple location points of multiple terminal devices that have established communication connections with the first roadside device, the area within which the communication capability of the first roadside device can be reached can be determined, thereby conveniently and accurately obtaining the communication range of the first roadside device.

[0125] It is understandable that the multiple terminal devices at multiple location points indicated by the first communication status indication information may include: location points of different terminal devices at the same time, location points of the same terminal device at different times, and location points of different terminal devices at different times. For example, the multiple terminal devices at multiple location points may include: location point 1 of vehicle 1 at 1 a.m. on Monday and location point 2 of vehicle 2 at 1 a.m. on Monday, location point 1 of vehicle 1 at 1 a.m. on Monday and location point 3 of vehicle 1 at 1 p.m. on Monday, and location point 4 of vehicle 3 at 1 a.m. on Tuesday and location point 5 of vehicle 4 at 1 p.m. on Tuesday. That is to say, the embodiment of the present application does not limit whether the multiple location points indicated by the first communication status indication information are the location points of the same terminal device and whether they are location points collected at the same time.

[0126] In one possible implementation, the first communication status indication information may include: location information of the indicated multiple locations, operating status information of multiple communication modules in the indicated multiple terminal devices, connection status information between the indicated multiple terminal devices and the first roadside device, identification information of the first roadside device, and time information. The location information of the locations, operating status information of the communication modules, and time information are as described above and are not further described here.

[0127] The connection status information between a terminal device and a roadside device can be either connected or disconnected. The connected state indicates that the terminal device has established a communication connection with the roadside device, while the disconnected state indicates that the terminal device has not established a communication connection with the roadside device. Since the first communication status indication information indicates that multiple terminal devices have established communication connections with the first roadside device at multiple locations, the connection status information with the first roadside device in the first communication status indication information indicates a connected state.

[0128] The identification information of a roadside device can be used to identify different roadside devices. For example, the identification information of a roadside device can include the name, number, location information of the roadside device, the identifier of the communication module configured on the roadside device, or other user-defined identifiers. Therefore, the identification information of a first roadside device can include the name, number, RSU_ID of the RSU on the first roadside device, or other user-defined identifiers for the first roadside device.

[0129] The process of obtaining the first communication status indication information is described below.

[0130] Figure 3 FIG. 1 is a schematic diagram showing the structure of the communication system provided in the embodiment of the present application. Figure 3 As shown, the communication system includes a first roadside device 11 and a first terminal device 12. The first roadside device 11 can represent any roadside device, and the first terminal device 12 represents a terminal device that establishes a communication connection with the first roadside device 11. The first terminal device 12 includes but is not limited to devices such as vehicle-side devices and mobile terminals. The first roadside device 11 can be connected to one or more first terminal devices 12. Specifically, the first roadside device 11 can establish a communication connection with the first terminal device 12 through the communication module in the first terminal device 12. After the first terminal device 12 obtains its own traffic participant data, it can report the obtained traffic participant data to the first roadside device 11.

[0131] In one possible implementation, the traffic participant data of a terminal device may include the location information of the terminal device at the time the traffic participant data was collected, the time information of the traffic participant data collection, the operating status information of the communication module in the terminal device, and the identification information of the roadside device to which the terminal device is connected. In one example, the location information can be recorded as Position, the operating status information can be recorded as Connection, the identification information of the roadside device can be recorded as RSU_ID, and the time information can be recorded as Time. Then, the traffic participant data of a terminal device can be recorded as (Position, Device, Connection, RSU_ID, Time). Since the first terminal device 12 is a terminal device that establishes a communication connection with the first roadside device 11, the operating status information of the communication module in the traffic participant data of the first terminal device 12 is "normal working state", and the identification information of the roadside device includes "identification information of the first roadside device 11". After receiving the traffic participant data reported by each first terminal device 12, the first roadside device 11 can generate first communication status indication information based on the received information.

[0132] It should be noted that, referring to Figure 3It can be seen that the first terminal device 12 that has established a communication connection with the first roadside device 11 can directly report the traffic participant data to the first roadside device 11, and other terminal devices that have not established a communication connection with the first roadside device 11 cannot directly report their traffic participant data to the first roadside device 11 (the situation of forwarding through other roadside devices is not considered here. Even if the first roadside device receives traffic participant data forwarded by other roadside devices, it can still filter out traffic participant data that has established a communication connection with the first roadside device 11 based on the identification information of the roadside devices). Therefore, the traffic participant data collected by the first roadside device 11 all comes from the first terminal device 12 that has established a communication connection with the first roadside device 11.

[0133] After obtaining the first communication status indication information, the first roadside device may execute step S202 to obtain the first distribution situation. In one example, the first roadside device may determine the first distribution situation based on the location information of the first location point (i.e., the location point of the first terminal device indicated by the first communication status indication information).

[0134] Figure 4 An exemplary schematic diagram of the first distribution situation is shown. Figure 4 As shown, the first terminal device (ie, the terminal device that establishes a communication connection with the first roadside device) establishes a communication connection with the first roadside device at multiple locations, and the location information of these locations is the first distribution situation. Figure 4 It can be seen that in the area close to the first roadside device, there are more location points that can establish communication connections with the first roadside device, and in the area far from the first roadside device, there are fewer location points that can establish communication connections with the first roadside device.

[0135] Afterwards, the first roadside device 11 may execute step S203 to obtain first communication capability information.

[0136] Figure 5 FIG. 1 is a schematic diagram showing the structure of the communication system provided in the embodiment of the present application. Figure 5As shown, the communication system includes: a first roadside device 11, a second terminal device 13 and a server 14. The first roadside device 11 can be any roadside device. The second terminal device 13 can represent a terminal device that establishes a communication connection with the server 14. Both the first roadside device 11 and the second terminal device 13 can establish a communication connection with the server 14 through a cellular network. After the second terminal device 13 obtains its own traffic participant data, it can report the obtained traffic participant data to the server 14. Considering that the second terminal device 13 may include the first terminal device 12 that establishes a communication connection with the first roadside device 11, that is, some second terminal devices 13 may have established a communication connection with both the server 14 and the first roadside device 11. Therefore, after the server 14 receives the traffic participant data reported by each second terminal device 13, it can filter out the traffic participant data that has established a communication connection with the first roadside device based on the working status information in each traffic participant data and the identification information of the roadside device. Specifically, the server 14 can filter out the working status information of the communication module as "normal working status" from the received traffic participant data, and the identification information of the roadside device includes the traffic participant data of "identification information of the first roadside device 11", and generate the first communication status indication information based on the filtered traffic participant data.

[0137] In one possible implementation, after the server 14 generates the first communication status indication information, it can execute step S202 to obtain the first distribution situation, or send the first communication status indication information to the first roadside device 11, and the first roadside device 11 executes step S202 to obtain the first distribution situation.

[0138] In one possible implementation, during the process of server 14 generating the first communication status indication information, server 14 may first, during the process of filtering traffic participant data, locate traffic participant data within a preselected range of the first roadside device within the collected traffic participant data. Then, from the traffic participant data within the preselected range, filter out traffic participant data whose operating status information is "normal operating status." For ease of description, in this embodiment of the present application, the dataset consisting of the traffic participant data filtered out at this time is referred to as dataset A. Subsequently, server 14 may filter out traffic participant data from dataset A whose roadside device identification information includes "identification information of the first roadside device 11." In this embodiment of the present application, the dataset consisting of the traffic participant data filtered out at this time is referred to as dataset B. The dataset consisting of the traffic participant data in dataset A excluding the traffic participant data in dataset B is referred to as dataset C. Among them, the preselected range is the area around the first roadside equipment 11. The preselected range can be determined based on the factory indicators of the communication range of the first roadside equipment 11 and the installation direction of the first roadside equipment. For example, based on the factory indicators of the communication range of the first roadside equipment, a certain margin can be reserved in the installation direction (for example, expanded by 3 meters, 5 meters, etc.) to obtain the preselected range.

[0139] Figure 6 The diagram below shows the distribution of terminal devices. Figure 6 As shown, within a preselected range, multiple terminal device locations are shown. At some locations, the terminal device can establish a communication connection with the first roadside device, while at other locations, the terminal device cannot. Traffic participant data corresponding to these locations that can establish a communication connection with the first roadside device is in dataset B, while traffic participant data corresponding to these locations that cannot establish a communication connection with the first roadside device is in dataset C. Figure 6 The position information of the position points in the data set B shown is the first distribution. Figure 6 It can be seen that in the area close to the first roadside device, there are more location points that can establish communication connections with the first roadside device, and in the area far from the first roadside device, there are fewer location points that can establish communication connections with the first roadside device.

[0140] Afterwards, the server 14 or the first roadside device 11 may obtain the first communication capability information in step S203 .

[0141] The following describes the process of generating the first communication capability information according to the first distribution in step S203. Figure 3 and Figure 5It can be seen that step S203 can be executed by the first roadside device or by the server. The following is explained by taking the first roadside device executing step S203 as an example. The process of the server executing step S203 can refer to the process of the first roadside device executing step S203, and will not be repeated in the embodiments of this application.

[0142] In one possible implementation, step S203 may include: the first roadside device directly generating first communication capability information based on a first distribution condition. The first distribution condition may be a density of first location points, where the first location points represent the location points of the first terminal device. In areas with a high density of first location points, the communication capability of the first roadside device is relatively strong; in areas with a low density of first location points, the communication capability of the first roadside device is relatively weak. Therefore, the first roadside device may generate the first communication capability information based on the density of the first location points.

[0143] In a possible implementation, the first roadside device may obtain second communication status indication information, determine a second distribution situation based on the second status indication information, and then generate first communication capability information based on the first distribution situation and the second distribution situation in step S203.

[0144] Among them, the second communication status indication information is used to indicate that the first at least one terminal device (for the convenience of description, in the embodiment of the present application, the first at least one terminal device is referred to as at least one third terminal device) establishes a communication connection with the second roadside device at the first at least one location point (for the convenience of description, in the embodiment of the present application, the first at least one location point is referred to as at least one third location point), and the distance between the at least one third location point and the first roadside device is less than a preset threshold. The acquisition process of the second communication status indication information can refer to the acquisition process of the first communication status indication information, replace the first roadside device in the first communication status indication information acquisition process with the second roadside device, and limit the location information in the traffic participant information to a range where the distance from the first roadside device is less than a preset threshold. Among them, the preset threshold can be set as needed. For distance, the preset threshold can be 100 meters, 200 meters, 500 meters or 1000 meters, etc. In one example, the first roadside device can determine the second distribution situation based on the location information of the third location point (i.e., the location point indicated by the second communication status indication information). The second distribution situation can refer to Figure 6 The location information of the location points in dataset B is added to the location information of the location points in dataset C.

[0145] A terminal device establishes a communication connection with a second roadside device at a location point at a distance less than a preset threshold from the first roadside device, indicating that the working status information of the communication module of the terminal device is "normal working state" and the terminal device is around the first roadside device. In this case, the terminal device is the third terminal device mentioned above, and the location point is the third location point mentioned above. A third terminal device may establish a communication connection with the first roadside device at a third location point (for example, Figure 6 The location point in the data set B shown in FIG) may also not have established a communication connection with the first roadside device (for example, Figure 6 The position points in the data set C shown). In an embodiment of the present application, the second distribution situation can be used as a comparison object for the first distribution situation, and the second distribution situation can be used to reflect the position points that actually exist around the first roadside device and can establish a communication connection with the first roadside device, and the first distribution situation can be used to reflect the position points where the first roadside device actually establishes a communication connection. In an embodiment of the present application, a stable connection rate can be determined based on the first distribution situation and the second distribution situation. Among them, the stable point connection rate can be the ratio of the number of first position points to the number of third position points. It can be understood that when the stable connection rate is large, it indicates that the number of position points where the first roadside device actually establishes a communication connection is relatively close to the number of position points that actually exist around the first roadside device and can establish a communication connection with the first roadside device, and the communication capability of the first roadside device is good. When the stable connection rate is small, it indicates that the number of position points where the first roadside device actually establishes a communication connection is significantly different from the number of position points that actually exist around the first roadside device and can establish a communication connection with the first roadside device, and the communication capability of the first roadside device is poor. Therefore, the first roadside device can generate the first communication capability information based on the stable connection rate.

[0146] In one possible implementation, the first roadside device may obtain third communication status indication information, and then determine a third distribution situation based on the third communication status indication information, and then generate first communication capability information based on the first distribution situation and the third distribution situation in step S203.

[0147] Among them, the third communication status indication information is used to indicate that the second at least one terminal device (for the convenience of description, in the embodiment of the present application, the second at least one terminal device is referred to as at least one second terminal device) establishes a communication connection with the server at the second at least one location point (for the convenience of description, in the embodiment of the present application, the second at least one location point is referred to as at least one second location point), and the at least one second terminal device has the ability to connect to the first roadside device, and the distance between the at least one second location point and the first roadside device is less than a preset threshold. The acquisition process of the third communication status indication information can be Figure 5, obtained by the server through screening from the received traffic participant information. Specifically, the server can screen out the traffic participant data whose location information is less than a preset threshold from the received traffic participant information and whose working status information of the communication module is "normal working status", and then obtain the third communication status indication information based on the screened traffic participant data. In one example, the first roadside device can determine the third distribution situation based on the location information of the second location point (i.e., the location point indicated by the third communication status indication information). The third distribution situation can refer to Figure 6 The location information of the location points in dataset B is added to the location information of the location points in dataset C.

[0148] A terminal device establishes a communication connection with a server at a location less than a preset threshold from a first roadside device, and the operating status information of the terminal device's communication module is "normal operation," indicating that the terminal device is near the first roadside device and capable of connecting to the first roadside device. In this case, the terminal device is the aforementioned second terminal device, and the location is the aforementioned second location. If the first roadside device fails to establish a communication connection with the third terminal device, this indicates that the first roadside device's communication capability at the corresponding second location is poor; if the first roadside device establishes a communication connection with the third terminal device, this indicates that the first roadside device's communication capability at the corresponding third location is strong. Therefore, in this embodiment of the present application, the third distribution can be used as a comparison object for the first distribution, with the third distribution reflecting the actual locations around the first roadside device that can establish a communication connection with the first roadside device, and the first distribution reflecting the locations where the first roadside device has actually established a communication connection. In this embodiment of the present application, a stable connection rate can be determined based on the first and third distributions. The stable point connection rate can be the ratio of the number of first location points to the number of second location points. It can be understood that when the stable connection rate is high, it indicates that the number of location points at which the first roadside device has actually established a communication connection is relatively close to the number of location points actually existing around the first roadside device that can establish a communication connection with the first roadside device, indicating that the communication capability of the first roadside device is relatively good. When the stable connection rate is low, it indicates that the number of location points at which the first roadside device has actually established a communication connection is significantly different from the number of location points actually existing around the first roadside device that can establish a communication connection with the first roadside device, indicating that the communication capability of the first roadside device is relatively poor. Therefore, the first roadside device can generate first communication capability information based on the stable connection rate.

[0149] In one possible implementation, step S203 may include: determining multiple grids based on a preselected range of the first roadside device; merging grids whose grid indicators meet the first condition among the multiple grids to obtain a merged grid, and continuing to merge grids whose grid indicators meet the first condition among the existing grids until there are no grids that meet the first condition; for any grid, determining the grid as a communication area, and determining the communication capability level of the grid based on the indicator range to which the grid indicator of the grid belongs; and determining the first communication capability information based on the location information and communication capability level of each grid.

[0150] In one example, determining multiple grids based on a preselected range of the first roadside device may include: gridding the preselected range of the first roadside device to obtain the multiple grids. In another example, determining multiple grids based on the preselected range of the first roadside device may include: taking the intersection of the preselected range of the first roadside device and the first road to obtain an area to be divided; and gridding the area to be divided to obtain the multiple grids. The first road may represent the road where the first roadside device is located or the roads surrounding the first roadside device. The association between the first road and the first roadside device may be pre-set when the first roadside device is deployed.

[0151] The grid indicator is the density or stable connection rate of the first location point in the grid, and the corresponding first condition is that the density difference is less than a first preset threshold or the stable connection rate difference is less than a second preset threshold. The first preset threshold and the second preset threshold can be set as needed. For example, the first preset threshold can be 0.2 / ㎡, and the second preset threshold can be 0.1. This embodiment of the application does not limit the first preset threshold and the second preset threshold.

[0152] Figure 7 Schematic diagram showing an exemplary grid in an embodiment of the present application. Figure 7 As shown, based on Figure 4 In the first distribution case shown, the preselected range of the first roadside equipment is divided into a plurality of grids. In one example, the area to be divided is evenly divided into a plurality of grids (such as Figure 7 This facilitates statistical management. Of course, other methods can also be used to divide the area to be divided into multiple grids. For example, the area of ​​the grids in areas closer to the first roadside device may be smaller than the area of ​​the grids in areas farther from the first roadside device (not shown). This can reduce the number of calculations and merging times.

[0153] After the grids are divided, the density of the first position point of each grid can be determined as the grid index of each grid. After the grid index of each grid is determined, the grids whose grid indexes meet the first condition in the plurality of grids can be merged to obtain a merged grid.

[0154] Afterwards, the grid index of each grid obtained after the previous round of merging is determined, and grids whose grid indexes satisfy the first condition among the existing grids are continuously merged until no grids satisfying the first condition exist. Figure 8 An exemplary schematic diagram showing the result of merging the grids in the embodiment of the present application is shown. Figure 8 As shown, Figure 7 The grids shown are ultimately merged into Region 1 and Region 2. The density of the first location points in Region 1 is low, while the density of the first location points in Region 2 is high. This indicates that the first roadside equipment has communication capability in Region 1, but the capability is poor, while it has communication capability in Region 2, and the capability is strong.

[0155] Figure 9 Schematic diagram showing an exemplary grid in an embodiment of the present application. Figure 9 As shown, based on Figure 6 The distribution of terminal devices shown is divided into multiple grids within the preselected range of the first roadside device. After the grids are divided, the stable connection rate of each grid can be determined as the grid index of each grid. After determining the grid index of each grid, the grids whose grid index meets the first condition can be merged to obtain a merged grid. Subsequently, the grid index of each grid obtained after the previous merging round is determined, and the merging of existing grids whose grid index meets the first condition continues until no grid meets the first condition. Figure 10 An exemplary schematic diagram showing the result of merging the grids in the embodiment of the present application is shown. Figure 10 As shown, Figure 9 The grids shown are eventually merged into Region 1 and Region 2. Region 1 has a lower stable connection rate, while Region 2 has a higher stable connection rate. This indicates that the first roadside equipment has communication capability in Region 1, but the capability is poor, while it has communication capability in Region 2, and the capability is strong.

[0156] When there is no grid that meets the first condition, that is, when the grids cannot be merged further, for any grid, the grid is determined as a communication area, and the communication capability level of the communication area is determined based on the indicator range to which the grid indicator of the communication area belongs; based on the location information and communication capability level of each communication area, the communication capability information of the first roadside device can be determined.

[0157] In an embodiment of the present application, each indicator range corresponds to a communication capability level. Based on the indicator range to which the grid indicator of the communication area belongs, determining the communication capability level of the communication area includes: when the grid indicator of the communication area belongs to the first indicator range, determining the communication capability level of the communication area as the first communication capability level. The first indicator range is any one of the indicator ranges, and the first communication capability level is the communication capability level corresponding to the first indicator range. Figure 8 and Figure 10 For example, there are two communication areas: area 1 and area 2, where the grid index of area 1 belongs to index range 1, and the grid index of area 2 belongs to index range 2. It can be determined that the communication capability level of the first roadside device in area 1 is level 1, and the communication capability level in area 2 is level 2.

[0158] In one example, the grid indicator of the communication area falling within the first indicator range may include: density within the first range, and / or stable connection rate within the second range. The first range and the second range can be set as needed and are not limited in this embodiment of the application.

[0159] In one example, the communication capability levels may include: blind spot, weak communication capability, average communication capability, and strong communication capability. In another example, the communication capability levels may include: low, medium, and high. In another example, the communication capability levels may include: first, second, third, and fourth levels, etc. It will be understood that the above is merely an exemplary description of the communication capability levels, and the embodiments of the present application do not limit the manner in which the communication capability levels are divided or the number of divisions.

[0160] In one possible implementation, the first communication capability information may be used to indicate the communication capability of the first roadside device. For example, the first communication capability information may indicate the areas in which the first roadside device can communicate and the areas in which it cannot communicate. For example, the first roadside device may be able to communicate with terminal devices within a range of 200 meters but unable to communicate with terminal devices beyond 200 meters.

[0161] In a possible implementation, the first communication capability information may be used to indicate the communication capability of the first area and the first roadside device within the first area.

[0162] Among them, the first area can represent any area. In one example, the first area can be the first area on the first road. The first area can be rectangular, sector-shaped, elliptical or other shapes. The embodiment of the present application does not limit the shape and area of ​​the first area. For example, the first roadside equipment has a good communication effect in the area within 100 meters, that is, the communication capability is strong communication capability; the communication effect in the area of ​​100 to 150 meters is average, that is, the communication capability is medium communication capability; the communication effect in the area of ​​150 to 200 meters is poor, that is, the communication capability is weak communication capability; and it cannot communicate with the area beyond 200 meters, that is, the communication capability is unable to communicate.

[0163] In a possible implementation, the first communication capability information may be used to indicate the communication capability of the first scenario, the first area, and the first roadside device within the first area under the first scenario.

[0164] The "scene" in the embodiment of the present application is used to identify the environment in which the device with communication function is located (for example, the environment in which the first roadside device is located), or to identify the environment in which the communication object of the device with communication function is located (for example, the environment in which vehicles or pedestrians are located). Among them, the first scene can represent any scene. For example, the first scene includes but is not limited to scenes that affect communication capabilities, such as daytime, nighttime, sunny days, cloudy days, windy and sandy days, rainy and snowy days, and foggy days. It can be understood that the communication range of the first roadside device on a sunny day is greater than the communication range on cloudy days, windy and sandy days, rainy and snowy days, and foggy days. The communication range of the first roadside device is different depending on the size of the wind and sand, the intensity of the rain and snow, or the level of the fog. The communication range may be smaller when the traffic volume is large during the day, and the communication range may be larger when the traffic volume is small at night. Therefore, in the embodiment of the present application, the communication capability of the first roadside device can be described by scene, so that the accuracy of the communication capability of the first roadside device is higher. For example, in the scene of a sunny day, the first roadside device is Figure 10 The communication capability of area 1 is shown as medium communication. Figure 10 The communication capability of area 2 is shown as strong communication; in foggy weather, the first roadside equipment Figure 10 The communication capability of area 1 is weak. Figure 10 The communication capability of area 2 is shown as medium communication.

[0165] It should be noted that when the first communication capability information indicates the communication capability of the first scenario, the first area, and the first roadside device within the first area under the first scenario, a scenario tag can be added to the aforementioned traffic participant data, so that the first communication status indication information, the second communication status indication information, and the third communication status indication information under the first scenario can be obtained. If the aforementioned traffic participant data is not added with a scenario tag, before obtaining the traffic participant data under the first scenario, the traffic participant data under the first scenario can be obtained in combination with third-party information (for example, time information and historical weather information).

[0166] At this point, the first communication capability information of the first roadside device has been obtained. In this application, the method for obtaining communication capability information for other roadside devices can refer to the method for obtaining the first communication capability information of the first roadside device, and will not be repeated here. For example, the method for obtaining the second communication capability information of the second roadside device can refer to the method for obtaining the first communication capability information of the first roadside device.

[0167] In one possible implementation, the first communication capability information of the first roadside device can be associated with a road sign. This allows for the communication capability information of each roadside device along a road or section to be retrieved before planning a route or before a traffic participant plans to include a road or section. This allows the roadside communication capability of each area along the road or section to be determined, thereby improving safety.

[0168] In one possible implementation, the first communication capability information can be stored as map data. In this way, when the vehicle is performing intelligent driving, it can obtain the first communication capability information from the map to determine whether the driver needs to take over the vehicle when driving to a certain area, whether the confidence of the information from the first roadside device needs to be reduced in a certain area, or whether a certain area needs to be avoided when planning a route, thereby improving safety. It is understandable that the first communication capability information can be associated with the first roadside device and then stored as map data. The communication capability information of other roadside devices (such as the second communication capability information of the second roadside device) can also be stored as map data to improve safety.

[0169] The application of the communication capability information is described below.

[0170] Considering that road obstruction and other factors may result in communication blind spots under multiple roadside devices, embodiments of the present application can integrate the communication capability information of each roadside device to form an overall communication coverage capability. In one possible implementation, the method further includes: generating multiple communication capability information for multiple roadside devices; and generating communication blind spot information based on the multiple communication capability information.

[0171] The plurality of communication capability information is used to indicate the communication capabilities of a plurality of roadside devices. Specifically, the plurality of roadside devices includes the first roadside device, and the plurality of communication capability information includes the first communication capability information. Furthermore, the plurality of roadside devices may also include one or more second roadside devices, and the plurality of communication capability information may include one or more second communication capability information.

[0172] The communication blind spot information is used to indicate areas not covered by one or more of the multiple roadside devices. In one example, the areas not covered by one or more of the multiple roadside devices include: absolute blind spots and / or relative blind spots, wherein none of the multiple roadside devices can reach a second threshold within the absolute blind spots, and some of the multiple roadside devices cannot reach a third threshold within the relative blind spots.

[0173] The second threshold and the third threshold can be set as needed, and the embodiment of the present application does not limit the second threshold and the third threshold. The second threshold and the third threshold can be used to indicate the expected or acceptable communication effect. When a roadside device cannot reach the second threshold or the third threshold, it indicates that the communication effect of the roadside device has not met expectations or is unacceptable. When a roadside device can reach the second threshold or the third threshold, it indicates that the communication effect of the roadside device can meet expectations or is acceptable. In one example, the second threshold and the third threshold include but are not limited to: meeting a preset communication capability level (for example, the corresponding communication capability level is level one or level two), or being within a preset indicator range (for example, the density falls within the preset indicator range, the stable connection rate falls within the preset indicator range), etc. When a roadside device does not reach the second threshold in an area, it indicates that the communication effect of the roadside device in the area is poor, and the reliability and accuracy of the information obtained by the roadside device in the area are low (the confidence level is low and the information is not complete), and therefore, the area is a blind spot of the roadside device. In the embodiment of the present application, the second threshold and the third threshold can be the same or different, and there is no limitation on this.

[0174] Figure 11 An exemplary schematic diagram showing the blind area of ​​an embodiment of the present application. Figure 11 The figure shows the boundary between the blind and non-blind zones of roadside device 1, as well as the boundary between the blind and non-blind zones of roadside device 2. The area within the boundary is the non-blind zone, and the area outside the boundary is the blind zone. The intersection of the blind zone of roadside device 1 and the non-blind zone of roadside device 2, as well as the intersection of the non-blind zone of roadside device 1 and the blind zone of roadside device 2, is the relative blind zone. The intersection of the blind zones of roadside device 1 and 2 is the absolute blind zone.

[0175] by Figure 11Taking the roadside equipment 1 and the roadside equipment 2 as examples, assuming that the second threshold value and the third threshold value are the same, the process of determining the relative blind spot and the absolute blind spot is described.

[0176] In one possible implementation, when a communication connection is established between roadside equipment 1 and roadside equipment 2, the communication capability of an area is determined based on the best communication capability of roadside equipment 1 or roadside equipment 2. For an area, if the communication capabilities of both roadside equipment 1 and roadside equipment 2 do not reach a second threshold, the area can be determined to be an absolute blind spot. In this case, a relative blind spot may not be marked.

[0177] In one possible implementation, when no communication connection is established between the roadside device 1 and the roadside device 2, the area where the communication capability of the roadside device 1 does not reach the second threshold but the communication capability of the roadside device 2 reaches the second threshold, and the area where the communication capability of the roadside device 2 does not reach the second threshold but the communication capability of the roadside device 1 reaches the second threshold, are determined as relative blind spots; the area where the communication capabilities of both do not reach the second threshold is determined as an absolute blind spot.

[0178] In one example, different identifiers can be added for absolute blind spots and relative blind spots. For example, a first identifier can be added for absolute blind spots, and a second identifier can be added for relative blind spots. This allows users to determine whether a blind spot is absolute or relative based on the identifiers. Optionally, when identifying relative blind spots, the relative blind spot can be associated with the identifier of a roadside device to clearly identify which roadside device a relative blind spot belongs to.

[0179] In another example, the communication capability information of a roadside device can be associated with the roadside devices with which it has established communication connections. This allows the user to determine which roadside devices the roadside device has established communication connections with, thereby determining where the absolute blind spot is and where the relative blind spot is.

[0180] In one possible implementation, the method further includes generating early warning information based on the first communication capability information. The early warning information may be used to prompt a driver to take over the vehicle in the second area, perform fault detection on the first roadside device, update the software of the first roadside device, adjust the deployment of the first roadside device, reduce the confidence level of information from the first roadside device in the second area, or avoid the second area when planning a route, wherein the first communication capability information indicates that the communication capability of the first roadside device in the second area is below a first threshold.

[0181] Among them, the first communication capability information indicates that the communication capability of the first roadside device in the second area is lower than the first threshold. The first threshold can be set as needed. In one example, being lower than the first threshold may include but is not limited to: not reaching a preset communication capability level (for example, not reaching a first-level communication capability level or not reaching a second-level communication capability level, etc.), the density of the first location point not reaching a preset density threshold, and the stable connection rate not reaching a preset stability threshold. One or more of the density threshold and the stability threshold here can be set as needed, and the embodiments of the present application do not impose any restrictions. Considering that the second threshold and the third threshold are used to determine blind spots, the first threshold is used for early warning, and early warning is required in areas that are not blind spots but have poor communication effects, therefore, in one example, the first threshold may be greater than (higher than) or equal to the second threshold and the third threshold.

[0182] Because the communication capability of the first roadside device in the second area is below the first threshold, the first roadside device's communication performance in the second area is poor. The first roadside device cannot accurately and comprehensively communicate with the terminal devices in the second area. Therefore, there is no guarantee that the first roadside device can transmit the information it obtains (including its own perceived information and information collected from other devices) to every terminal device in the second area. Therefore, when the vehicle is autonomously driving in the second area, the data sources may be insufficient, posing a high risk. The driver can take over the vehicle in the second area. Simultaneously, a fault check can be performed on the first roadside device to determine whether a fault in the first roadside device is causing the poor communication performance in the second area, particularly if the second area is close to the first roadside device. The first roadside device's software can also be updated or its deployment adjusted to optimize its communication capabilities. Furthermore, due to the first roadside device's poor communication performance in the second area, the information collected by the first roadside device from the terminal devices in the second area may not accurately represent the actual situation in the second area. Therefore, the confidence level of the information obtained by the first roadside device in the second area needs to be reduced. Since the communication effect of the first roadside device in the second area is poor, the second area can be avoided during route planning, which can reduce the possibility of accidents after the vehicle enters the second area. Especially for self-driving vehicles, avoiding the second area does not require the driver to take over the vehicle, which can effectively improve the user experience.

[0183] In an embodiment of the present application, the communication capability information of each roadside device can also be sent to other devices for use by other devices. For example, it can be provided to vehicle-side devices, mobile terminals or management devices of roadside devices. Figure 12 FIG. 1 is a flow chart showing a method for using communication capability information according to an embodiment of the present application. Figure 12As shown, the method for using the communication capability information may include:

[0184] Step S301: Obtain communication capability information.

[0185] In this step, one or more pieces of communication capability information for one or more roadside devices may be obtained. For example, the first communication capability information for a first roadside device may be obtained. In another example, the first communication capability information for the first roadside device and one or more pieces of second communication capability information for one or more second roadside devices may be obtained. The process for generating the second communication capability information can refer to the process for generating the first communication capability information and will not be further described here.

[0186] For any piece of communication capability information obtained, the communication capability information is used to indicate the communication capability of the area and the roadside device within the area. For example, the first communication capability information may be used to indicate the communication capability of the first area and the first roadside device within the first area. In one possible implementation, for any piece of communication capability information received, the communication capability information may be used to indicate the communication capability of the area, the scenario, and the roadside device within the area under the scenario. For example, the first communication capability information may be used to indicate the communication capability of the first roadside device within the first area under the first scenario.

[0187] In one possible implementation, the communication capability information may be stored as map data, and a device using the communication capability information, such as a vehicle-side device, may obtain the communication capability information from the map after downloading or updating the map.

[0188] Step S302: Based on the communication capability information, generate warning information, adjust the confidence level of the information from the roadside equipment in the area, or plan a driving route that does not pass through the area.

[0189] In this step, the communication capability of each roadside device for each area can be determined based on the received communication capability information, so as to know in which areas the communication capability with the terminal devices is strong and in which areas the communication capability with the terminal devices is poor. According to these communication capabilities, early warning information is generated, the confidence level of the information from the roadside device in the area is adjusted, or a driving route that does not pass through the area is planned.

[0190] In one possible implementation, the early warning prompt information is used to prompt the driver to take over the vehicle in the area, pay attention to avoid vehicles in the area, perform fault detection on the roadside equipment, reduce the confidence of information obtained by communication with the roadside equipment in the area, or avoid the area when planning a route, wherein the communication capability information indicates that the communication capability of the roadside equipment in the area is lower than a first threshold.

[0191] It is understandable that for different devices, different actions are performed based on the communication capability information, and for the same device, different actions can be performed based on the communication capability information. Figures 13 to 15 Step S302 will be described.

[0192] Figure 13 The following is an interactive diagram showing a method for using communication capability information provided by an embodiment of the present application. Figure 13 As shown, the method for using the communication capability information may include:

[0193] Step S401: The communication capability information generating device sends communication capability information to the vehicle-side device.

[0194] In an embodiment of the present application, the communication capability information can be generated by a server or a roadside device. The communication capability information generating device can be a roadside device, a server, or a roadside device and a server. When the communication capability information is generated by the server, the server can directly send the communication capability information to the vehicle-end device through the cellular network. Optionally, when the communication capability information is generated by the server, the server can also send the communication capability information to the roadside device through the cellular network, and then the roadside device forwards the communication capability information to the vehicle-end device through the V2X network. When the communication capability information is generated by the roadside device, the roadside device can directly send the communication capability information to the vehicle-end device through the V2X network. Of course, the communication capability information can include both the communication capability information generated by the roadside device and the communication capability information generated by the server.

[0195] Step S402: The vehicle-side device receives communication capability information.

[0196] In this step, the communication capability information received by the vehicle-side device comes from the server and / or roadside equipment.

[0197] In step S403, the vehicle-side device determines an area where the communication capability of the roadside device is lower than a first threshold value based on the communication capability information, and generates an early warning prompt message for reminding the driver to take over the vehicle in the area.

[0198] Based on the received communication capability information, the vehicle-side device can identify areas where the communication capability is below a first threshold. In these areas, the ability of the roadside device to establish a communication connection with traffic participants is poor. Some actual traffic participants may be unable to establish a communication connection with the roadside device, or the communication quality of the established connection may be poor. Therefore, the risk of autonomous driving in these areas is high. To improve safety, the vehicle-side device can generate a warning message to remind the driver to take over the vehicle in areas where the communication capability is below the first threshold.

[0199] In step S404, the vehicle-side device adjusts the confidence level of the information from the roadside device in each area based on the communication capability information.

[0200] Based on the communication capability information, the vehicle-side device can determine which roadside devices have better communication performance in which areas, and which roadside devices have worse communication performance in which areas. For example, if roadside device 1 has better communication performance in area 1 and worse performance in area 2, and roadside device 2 has better communication performance in area 2 and worse performance in area 1, the vehicle-side device can increase the confidence level of information from roadside device 1 in area 1 and decrease it in area 2; and increase the confidence level of information from roadside device 2 in area 2 and decrease it in area 3. This allows the vehicle to increase its reliance on the information it perceives about area 2 and on information from roadside device 2 when autonomous driving in area 2, while decreasing its reliance on information from roadside device 1, thereby improving autonomous driving safety.

[0201] In step S405, the vehicle-side device determines, based on the communication capability information, an area where the communication capability of the roadside device is lower than a first threshold, and ensures that the driving path does not pass through the area when planning the driving path.

[0202] After the vehicle-side device determines the areas where the communication capability is lower than the first threshold based on the received communication capability information, it can avoid these areas when planning the implementation path, which is conducive to improving the safety of autonomous driving.

[0203] It is understandable that the vehicle-side device may execute one or more of steps S403 to S405. When executing multiple steps S403 to S405, there is no restriction on the execution order.

[0204] In one possible implementation, after receiving the communication capability information, the vehicle-side device can store the communication capability information as map data. In this way, when the vehicle-side device performs intelligent driving later, it can obtain the communication capability information from the map, thereby determining whether the driver needs to take over the vehicle when driving to a certain area, whether the confidence of the information from a certain roadside device needs to be reduced in a certain area, or whether a certain area needs to be avoided when planning a route, thereby improving safety.

[0205] Figure 14 The following is an interactive diagram showing a method for using communication capability information provided by an embodiment of the present application. Figure 14 As shown, the method for using the communication capability information may include:

[0206] Step S501: The communication capability information generating device sends communication capability information to the mobile terminal.

[0207] Step S502: The mobile terminal receives communication capability information.

[0208] Step S501 and step S502 may refer to step S401 and step S402 respectively, and are not described in detail here.

[0209] In step S503, the mobile terminal determines an area where the communication capability of the roadside equipment is lower than a first threshold value based on the communication capability information, and generates a warning prompt message for reminding the mobile terminal user to avoid vehicles in the area.

[0210] For areas where the communication capability is lower than the first threshold, the communication effect of the roadside equipment is poor, and it may not be possible to establish a communication connection with some terminal devices in these areas, or the communication effect of the established communication connection is poor, and information cannot be sent to the mobile terminal in a timely manner, thereby failing to promptly assist the user of the mobile terminal in discovering the presence of vehicles or pedestrians around it. Therefore, after the mobile terminal determines the area where the communication capability is lower than the first threshold based on the received communication capability information, it can generate an early warning prompt information to remind the mobile terminal user to pay attention to avoid vehicles in the said area, which is beneficial to improving the travel safety of the user.

[0211] Figure 15 The following is an interactive diagram showing a method for using communication capability information provided by an embodiment of the present application. Figure 15 As shown, the method for using the communication capability information may include:

[0212] Step S601: The communication capability information generating device sends communication capability information to the management device of the roadside device.

[0213] Step S602: The management device receives communication capability information.

[0214] Step S601 and step S602 may refer to step S401 and step S402, and will not be repeated here.

[0215] In step S603, the management device determines, based on the communication capability information, that there is an area where the communication capability of the roadside equipment is lower than the first threshold, and generates early warning information to remind the administrator to perform fault detection on the roadside equipment, update the software of the roadside equipment, or adjust the deployment of the roadside equipment.

[0216] When there is an area where the communication capability is lower than the first threshold, it indicates that the roadside equipment may have a fault, or the communication capability of the roadside equipment needs to be further improved, or there are unreasonable aspects in the deployment of the roadside equipment. Therefore, the management equipment of the roadside equipment can remind the administrator to check the roadside equipment for faults, update the software of the roadside equipment, or adjust the deployment of the roadside equipment so that the roadside equipment can establish a communication connection with a wider range of terminal equipment, and the communication effect is improved.

[0217] Considering that there may be new green plants, buildings and other obstructions around the roadside equipment, the roadside sensor device of the roadside equipment may also be blocked by foreign objects or damaged, the roadside sensor device of the roadside equipment may cause recognition abnormalities due to climate or weather reasons (for example, high temperature, severe haze, dust), the software of the roadside equipment has been updated, the communication module of the roadside equipment has been replaced, etc., which may cause the communication range of the roadside equipment to change. Therefore, the communication capability generation method provided in the embodiment of the present application can update the generated communication capability information. The following is an example of the update process of the first communication capability information of the first roadside equipment.

[0218] In a possible implementation manner, the method further includes: updating the first communication capability information when a preset condition is met.

[0219] In one example, the preset conditions include but are not limited to: repairing the fault of the first roadside equipment; replacing the sensor of the first roadside equipment; or upgrading the first roadside equipment; the current value of the communication capability indicator indicated by the first communication capability information is abnormal relative to the statistical value of the communication capability indicator.

[0220] It is understandable that after the first roadside equipment undergoes fault repair, sensor replacement or upgrade, the communication capability of the roadside equipment is likely to change, so the first communication capability information needs to be updated to improve accuracy.

[0221] The following describes an anomaly in the current value of the communication capability indicator indicated by the first communication capability information relative to the communication capability indicator statistics. The current value of the communication capability indicator indicated by the first communication capability information may represent communication capability information obtained within a first time period before the current moment. The statistical value of the communication capability indicator indicated by the first communication capability information represents communication capability information obtained within a second time period before the current moment. The first time period is shorter than the second time period, and the time corresponding to the first time period is after the time corresponding to the second time period.

[0222] The method for generating the current value and statistical value of the communication capability indicator can refer to the method for generating the first communication capability information. The current value of the communication capability indicator can be obtained by limiting the time information of the traffic participant data used in generating the first communication capability information to a first time period. The statistical value of the communication capability indicator can be obtained by limiting the time information of the traffic participant data used in generating the first communication capability information to a second time period.

[0223] When the current value of the communication capability indicator and the statistical value of the communication capability indicator meet abnormal conditions, it can be determined that the current value of the communication capability indicator is abnormal relative to the statistical value of the communication capability indicator. At this time, the current communication capability of the first roadside device has changed significantly compared with the previous one. Therefore, the first communication capability information needs to be updated to improve accuracy.

[0224] In one possible implementation, the abnormality of the current value of the communication capability indicator indicated by the first communication capability information relative to the communication capability indicator statistics includes: a difference between a first communication area corresponding to a target communication capability level and a second communication area is greater than a first difference threshold corresponding to the target communication capability level. The target communication capability level is any one of the communication capability levels possessed by the first roadside equipment, the first communication area represents the communication area corresponding to the target communication capability level indicated by the current value of the communication capability indicator, and the second communication area represents the communication area corresponding to the target communication capability level indicated by the communication capability indicator statistics.

[0225] For example, the current value of the communication capability indicator indicates that the communication capability level of area 3 is level 1 and the communication capability level of area 4 is level 2. The communication capability indicator statistics indicate that the communication capability level of area 5 is level 1 and the communication capability level of area 6 is level 2. When the difference between area 3 and area 5 is greater than the first difference threshold, and / or when the difference between area 4 and area 6 is greater than the first difference threshold, it indicates that the communication capability of the first roadside device has changed significantly. At this time, it can be determined that the current value of the communication capability indicator is abnormal relative to the communication capability indicator statistics. In one example, the first difference threshold can be used to represent the difference in position. When the distance between the position of area 3 and the position of area 5 is greater than the first difference threshold, it can be determined that the current value of the communication capability indicator is abnormal relative to the communication capability indicator statistics. In another example, the first difference threshold can represent the difference in area. When the difference between the area of ​​area 3 and the area of ​​area 5 is greater than the first difference threshold, it can be determined that the current value of the communication capability indicator is abnormal relative to the communication capability indicator statistics. It should be noted that the above is only an exemplary description of the first difference threshold and cannot be used as a limitation.

[0226] Optionally, a weighted operation may be performed on the differences between the first communication area and the second communication area corresponding to each communication capability level. When the result of the operation is greater than a second difference threshold, it is determined that the current value of the communication capability indicator is abnormal relative to the communication capability indicator statistical value. The second difference threshold can refer to the first difference threshold and is not further described here.

[0227] In the embodiment of the present application, whether an abnormality occurs is determined by comparing communication areas with the same communication capability level, which is relatively convenient, highly readable, and easy for users to understand.

[0228] In one possible implementation, the abnormality of the current value of the communication capability indicator indicated by the first communication capability information relative to the communication capability indicator statistics includes: in the communication area corresponding to the target communication capability level in the communication capability indicator statistics, the ratio of the data volume of the position points in the current data set B to the number of position points in the current data set A is less than the third difference threshold.

[0229] Among them, the current data set A is used to indicate the traffic participant data collected in the first time period before the current moment, which are within the preselected range of the first roadside device and whose working status information is a normal working status. The current data set B represents the traffic participant data indicated by the current data set A, whose device identification information includes the identification information of the first roadside device.

[0230] The ratio of the number of location points in the current data set B to the number of location points in the current data set A is less than the third difference threshold, indicating that a large number of communication failures have occurred in the communication area corresponding to the target communication capability level. In other words, the communication effect between the current first roadside device and the terminal devices in the communication area corresponding to the target communication capability level is poor. Therefore, it can be determined that the current value of the communication capability indicator is abnormal relative to the statistical value of the communication capability indicator. The third difference threshold can be set as needed. In one example, the third difference threshold corresponds to the target communication capability level. The stronger the communication capability corresponding to the target communication capability level, the smaller the value of the third difference threshold; the weaker the communication capability corresponding to the target communication capability level, the larger the value of the third difference threshold.

[0231] For example, the communication area corresponding to the target communication capability level "Level 1" in the communication capability indicator statistics is Area 5, and the third difference threshold corresponding to the target communication capability level "Level 1" is Threshold 1. In Area 5, the number of location points in the current dataset B is "Number 1", and the number of location points in the current dataset A is "Number 2". If the ratio of Number 1 to Number 2 is less than the third difference threshold corresponding to Level 1, it can be determined that the current value of the communication capability indicator is abnormal relative to the communication capability indicator statistics.

[0232] In the embodiment of the present application, by comparing the number of location points during the process of generating the current value of the communication capability indicator to determine whether an abnormality occurs, the abnormality can be discovered in time, and an update can be triggered immediately if an abnormality is detected.
