[0082] Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application. Please refer to [link / reference]. Figure 1 It includes multiple roadside units 101 and management equipment 102.

[0083] In intelligent transportation scenarios, roadside units 101 can be installed on specific road sections or intersections. The roadside units 101 can store infrastructure information and send the roadside infrastructure information to road participants (e.g., vehicles, pedestrians, and motorcycles) passing through the road section. The infrastructure information can be sent via C-V2X broadcast, unicast, or multicast.

[0084] The management device 102 can manage multiple roadside units 101. The management device 102 can determine the installation location of each roadside unit 101 and send corresponding infrastructure information to the roadside unit 101 according to the installation location.

[0085] A processing chip can be installed in the roadside unit 101. The roadside unit 101 can determine the current real-time information of the corresponding road segment. Based on the current real-time information, it can determine the first error information of the infrastructure information. The roadside unit 101 can determine the target adjacent RSU, compare and analyze the first error information with the second error information of the target adjacent RSU, determine the target error information, and send the target error information to the management device 102.

[0086] In existing technologies, staff can collect infrastructure information for each road segment where a Roadside Unit (RSU) is located and store this information in the RSU so that the RSU can send the infrastructure information to vehicles. However, the infrastructure information collected by staff is prone to errors, and road conditions in the area where the RSU is located may change, resulting in low accuracy of the infrastructure information.

[0087] In this embodiment, the current real-time information of the road segment corresponding to the target RSU can be obtained. Based on the current real-time information, the first error information of the infrastructure information in the target RSU can be determined. The second error information of the target adjacent RSU and the first error information are compared and analyzed to determine the target error information of the road segment corresponding to the target RSU. The management device can update the infrastructure information according to the target error information, which can improve the accuracy of the infrastructure information.

[0088] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0089] Figure 2 This is a flowchart illustrating an error analysis method provided in an embodiment of this application. Please refer to... Figure 2 The method may include:

[0090] S201. Determine the current real-time information of the road segment corresponding to the target RSU.

[0091] The execution entity in this application embodiment can be a roadside unit or an error analysis device installed in the roadside unit. The error analysis device can be implemented by software or by a combination of software and hardware.

[0092] The target RSU can periodically obtain real-time information about its corresponding road segment to ensure that infrastructure information can be updated in a timely manner after the road segment information changes.

[0093] Current real-time information can include multiple real-time data points.

[0094] The current real-time information can be determined as follows: obtain multiple first real-time information from multiple time periods; compare and analyze the multiple first real-time information to determine the current real-time information.

[0095] For example, suppose we obtain the first real-time information 1 in time period 1, the first real-time information 2 in time period 2, and the first real-time information 3 in time period 3. We can compare and analyze the first real-time information 1, the first real-time information 2, and the first real-time information 3 to determine the current real-time information.

[0096] S202. Based on the current situation information, determine the first error information of the infrastructure information in the target RSU.

[0097] Infrastructure information can include multiple initial data, such as intersection data, lane data, road connection relationships, lane-level map data, traffic light switching zones, right-turn lanes and bus stops, and the current status data of traffic lights at at least one intersection.

[0098] Among them, intersection data, lane data, road connection relationships, lane-level map data, traffic light turn-off zones, right-turn lanes, and bus stops are part of the regional map information.

[0099] The first error information can be determined as follows: determine at least one infrastructure type; among multiple real-time data and multiple initial data, determine at least one real-time data and at least one initial data corresponding to each infrastructure type; determine the first error information based on at least one real-time data and at least one initial data corresponding to each infrastructure type.

[0100] For example, suppose there are 3 infrastructure types, namely infrastructure type 1, infrastructure type 2 and infrastructure type 3, and suppose there are 5 current data and 5 initial data. The current data and initial data can be shown in Table 1. Then the current data and initial data corresponding to each infrastructure type can be determined as shown in Table 2.

[0102] Live Data 1 Infrastructure Type 1 Initial data 1 Infrastructure Type 1 Live Data 2 Infrastructure Type 1 Initial data 2 Infrastructure Type 1 Live Data 3 Infrastructure Type 2 Initial data 3 Infrastructure Type 2 Live Data 4 Infrastructure Type 3 Initial data 4 Infrastructure Type 3 Real-time data 5 Infrastructure Type 2 Initial data 5 Infrastructure Type 2

[0103] Table 2

[0104]

[0105] S203. Identify the target RSU and its nearest neighbor RSU.

[0106] In some embodiments, the target RSU may include two adjacent RSUs, namely the RSU of the road segment preceding the target RSU and the RSU of the road segment following the target RSU.

[0107] The target neighboring RSU can be determined as follows: Among the neighboring RSUs of the target RSU, the first neighboring RSU is determined; if the first neighboring RSU is not paired, the first neighboring RSU is determined as the target neighboring RSU; if the first neighboring RSU is paired, the second neighboring RSU of the target RSU is determined, and the target neighboring RSU is determined based on the second neighboring RSU.

[0108] For example, suppose RSU1, RSU2 and RSU3 are three adjacent installed RSUs, RSU2 is the target RSU, and the first neighboring RSU is RSU1. If RSU1 is not paired, then RSU1 is identified as the target neighboring RSU; if RSU1 is paired, then RSU3 is identified as the second neighboring RSU. The target neighboring RSU is determined based on RSU3.

[0109] S204. Compare and analyze the first error information with the second error information of the target's neighboring RSUs to determine the target error information, and send the target error information to the management device of the target RSU.

[0110] The target's nearest RSU can determine its corresponding second error information based on the execution process of steps S201-S202, which will not be elaborated here.

[0111] The target error information may include the target error value of at least one initial data corresponding to each infrastructure type.

[0112] The management equipment can store infrastructure information for multiple road segments. It can update the infrastructure information based on the target error information to obtain the updated infrastructure information and send it to the target RSU.

[0113] The error analysis method provided in this application embodiment can compare and analyze the second error information and the first error information of the target adjacent RSU, determine the target error information of the road segment corresponding to the target RSU, send the target error information to the management device of the target RSU, and the management device can update the infrastructure information according to the target error information, thereby improving the accuracy of the infrastructure information.

[0114] Figure 3 This is a flowchart illustrating another error analysis method provided in an embodiment of this application. Please refer to... Figure 3 The method may include:

[0115] S301. Obtain multiple first-real-time information for multiple time periods.

[0116] The first real-time information may include multiple dynamic data within that time period, such as the stopping position data, heading data, and motion status data of road participants.

[0117] Stop location data can determine the actual location of the stop line on that road segment.

[0118] Heading data can determine the actual status of road turning signs in each lane of the road segment.

[0119] Motion status data can determine the actual duration of red / yellow / green lights on that road segment.

[0120] S302. Compare and analyze multiple pieces of first real-time information to determine the current real-time information.

[0121] The current real-time information can be determined as follows: compare and analyze multiple dynamic data for each first real-time information to determine multiple sets of dynamic information; analyze each set of dynamic information to determine the current real-time information.

[0122] The first set of real-time information may include road users who do not follow traffic rules. By analyzing each set of dynamic information, the impact of erroneous data can be reduced.

[0123] For example, suppose there are 3 pieces of first real-time information, and each piece of real-time information has 3 pieces of dynamic data. Suppose the first real-time information can be as shown in Table 3. Then, three sets of dynamic information can be determined, namely dynamic information 1, dynamic information 2 and dynamic information 3. Dynamic information 1 can include dynamic data 11, dynamic data 21 and dynamic data 31. Dynamic information 2 can include dynamic data 12, dynamic data 22 and dynamic data 32. Dynamic information 3 can include dynamic data 13, dynamic data 23 and dynamic data 33.

[0124] Table 3

[0125]

[0126] Each set of dynamic information can be analyzed to determine the current real-time situation.

[0127] For example, assuming that dynamic information 1 is motion state data, dynamic information 1 includes 3 dynamic data, namely dynamic data 11, dynamic data 21 and dynamic data 31, then the first actual duration of the red light, the second actual duration of the green light and the third actual duration of the yellow light can be analyzed based on the 3 dynamic data to obtain the actual duration of the red / yellow / green light in the current real-time information.

[0128] S303. Identify at least one type of infrastructure.

[0129] Infrastructure types can include stop line types, road turn sign types, and traffic light types.

[0130] S304. Among multiple real-time data and multiple initial data, determine at least one real-time data and at least one initial data corresponding to each infrastructure type.

[0131] The execution process of S304 can be found in the execution process of S202, and will not be repeated here.

[0132] S305. Determine the first error information based on at least one real-time data and at least one initial data corresponding to each infrastructure type.

[0133] The first error information may include at least one first error value corresponding to each infrastructure type.

[0134] For any infrastructure type, the first error information can be determined as follows: determine the actual data corresponding to each initial data; perform error analysis on each initial data and the actual data corresponding to each initial data to determine the first error value corresponding to each initial data, so as to obtain the first error information.

[0135] For example, assuming there are two infrastructure types, namely infrastructure type 1 and infrastructure type 2, and assuming the actual data and initial data corresponding to the infrastructure types can be as shown in Table 2, then the first error value 1 corresponding to initial data 1, the first error value 2 corresponding to initial data 2, the first error value 3 corresponding to actual data 3, and the first error value 4 corresponding to initial data 5 can be determined.

[0136] S306. Among the neighboring RSUs of the target RSU, determine the first neighboring RSU.

[0137] You can randomly select the first nearest RSU from the target RSU's neighboring RSUs.

[0138] S307. If the first neighboring RSU is not paired, then the first neighboring RSU is determined as the target neighboring RSU.

[0139] If the first neighboring RSU and its neighboring RSUs jointly determine the error information, then the first neighboring RSU is considered paired; otherwise, the first neighboring RSU is not paired.

[0140] S308. If the first neighboring RSU has been paired, then determine the second neighboring RSU of the target RSU, and determine the target neighboring RSU based on the second neighboring RSU.

[0141] The target neighboring RSU can be determined as follows: if the second neighboring RSU is not paired, then the second neighboring RSU is determined as the target neighboring RSU; if the second neighboring RSU is already paired, then after a preset time period, the pairing is searched again until the target neighboring RSU is determined.

[0142] If all of the target RSU's neighboring RSUs are already paired, the target RSU can periodically send pairing requests until it receives a pairing response, thus identifying the target neighboring RSUs.

[0143] S309. If there is a first error value in the first error information that is greater than the first threshold, then the first error information is determined as the target error information.

[0144] If there is a first error value in the first error information that is greater than the first threshold, it can be determined that the road segment where the target RSU is located has been modified, and the actual condition of the road segment is significantly different from the infrastructure information stored in the target RSU. Therefore, the first error information needs to be reported and is identified as the target error information.

[0145] S310. If there is no first error value greater than the first threshold in the first error information, then perform data processing on the first error information and the second error information to determine multiple difference values ​​for each infrastructure type.

[0146] If there is no first error value greater than the first threshold in the first error information, it can be determined that the road segment where the target RSU is located has not been modified. The error at this time comes from the measurement error when measuring each road segment, etc. The error situation of each road segment is basically the same and the error degree is small. It is necessary to compare with the second error information of the adjacent RSU to improve the accuracy of the target error information.

[0147] The second error information may include at least one second error value corresponding to each infrastructure type.

[0148] For any infrastructure type, at least one first error value and at least one second error value corresponding to that infrastructure type can be processed to obtain the difference value of that infrastructure type.

[0149] S311. If the mean of multiple difference values ​​is less than the second threshold, then the first error information is determined as the target error information.

[0150] If the mean of multiple difference values ​​is less than the second threshold, it can be determined that the error values ​​analyzed by the target RSU and the target neighboring RSU are consistent, and the first error information can be determined as the target error information.

[0151] Alternatively, the second error information can be determined as the target error information.

[0152] S312. If the average of multiple difference values ​​is greater than the second threshold, then determine the current real-time information of the target RSU for the next time period, until the target error information is determined.

[0153] If the mean of multiple difference values ​​is greater than the second threshold, it can be determined that the error values ​​analyzed by the target RSU and / or the target neighboring RSUs may be incorrect, and the current real-time information can be obtained again for analysis and processing.

[0154] The number of error analysis processes can be limited. For example, if the error analysis process reaches its third iteration, the error information with the larger error value will be directly identified as the target error information.

[0155] S313. Send target error information to the management device of the target RSU.

[0156] The execution process of S313 can be found in the execution process of S204, and will not be repeated here.

[0157] The error analysis method provided in this application can determine the modification status of the road segment corresponding to the target RSU by using first error information. If there is a first error value greater than a first threshold in the first error information, indicating that the road segment corresponding to the target RSU is being modified, the first error information can be identified as the target error information. If there is no first error value greater than the first threshold in the first error information, the second error information of the target adjacent RSU and the first error information of the target RSU are compared and analyzed to determine the target error information of the road segment corresponding to the target RSU, thereby improving the accuracy of the target error information. Management equipment can update infrastructure information based on the target error information, further improving the accuracy of infrastructure information.

[0158] Figure 4 This is a schematic diagram illustrating the structure of an error analysis method provided in an embodiment of this application. Please refer to [link / reference]. Figure 4 The system acquires multiple first-real-time information data from multiple time periods, compares and analyzes these multiple first-real-time information data to determine the current real-time information. The current real-time information includes multiple real-time data, and the infrastructure information includes multiple initial data.

[0159] At least one infrastructure type is identified. From multiple real-time data sets and multiple initial data sets, at least one real-time data set and at least one initial data set corresponding to each infrastructure type are determined. Based on the at least one real-time data set and at least one initial data set corresponding to each infrastructure type, first error information is determined. Target neighboring RSUs are identified. If a first error value greater than a first threshold exists in the first error information, the first error information is determined as target error information. If a first error value greater than the first threshold exists in the first error information, the first error information is compared and analyzed with the second error information of the target neighboring RSUs to determine the target error information.
