Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted below.

[0033] Terms such as "first", "second", and "third" in the description and claims of the present disclosure and the above accompanying drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0034] An embodiment of the present disclosure provides an information processing method. The information processing method can be applied to an electronic device, which includes but is not limited to a fixed device and / or a mobile device. For example, the fixed device includes but is not limited to a server, and the server can be a cloud server or a general server. For example, the mobile device includes but is not limited to: a vehicle-mounted terminal, a navigation device. As Figure 1 shown, the information processing method includes:

[0035] S101: Obtain the action range information corresponding to multiple speed limit signs of a first road link;

[0036] S102: Determine the target speed limit sign of the first road link based on the action range information corresponding to the multiple speed limit signs;

[0037] S103: When the action range of the target sign does not meet the preset conditions, combine the action range information corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road chain to adjust the action range of the target sign, and obtain the target action range information of the target speed limit sign.

[0038] Here, the speed limit signs include, but are not limited to, high speed limit signs, low speed limit signs, and speed limit removal signs. Speed limit signs are mainly used on highways and urban roads.

[0039] Here, the action range information includes at least one of the speed limit value and the action distance.

[0040] Figure 2 The schematic diagram of the speed limit sign with a clear action distance is shown. From Figure 2 it can be seen that Figure 2 the speed limit sign in Figure 3 has a clear action distance, and the action distance is 4374 meters. Figure 3 The schematic diagram of the speed limit sign with a clear scenario is shown. From Figure 3 it can be seen that

[0041] the speed limit sign in

[0042] This disclosure does not limit how the database obtains the speed limit signs included in the first road chain and the action range information corresponding to each speed limit sign.

[0043] In this way, the action range information corresponding to multiple speed limit signs on the first road chain can be quickly obtained, providing a guarantee for quickly determining the target speed limit sign and its action range information subsequently.

[0044] In other embodiments, obtaining the action range information corresponding to multiple speed limit signs on the first road chain includes: based on the identification information of the first road chain, obtaining from the database the speed limit signs included in the first road chain and the action range information corresponding to each speed limit sign.

[0045] In this way, multiple speed limit signs that match the actual situation of the current speed limit sign on the first road chain and their respective corresponding action range information can be obtained, which helps to make the target speed limit sign and its action range information adapt to the current road conditions and speed limit signs, and improves the rationality of the action range of the target speed limit sign.

[0046] Here, the target action range information of the target speed limit sign includes the speed limit value and / or the action distance of the target speed limit sign.

[0047] Here, the first road chain includes N speed limit signs and M target speed limit signs, where M is an integer greater than or equal to 0, N is an integer greater than or equal to 1, and M is less than or equal to N.

[0048] It should be noted that different scenarios may correspond to different preset conditions. The same scenario may correspond to one or more preset conditions.

[0049] The present disclosure does not impose mandatory limitations on the preset conditions, and the specific preset conditions can be set or adjusted according to the type of scenario or user requirements.

[0050] In the technical solution described in the embodiments of the present disclosure, the target speed limit sign of the first road chain is determined based on the action range information respectively corresponding to multiple speed limit signs on the first road chain; and then, in combination with the action range information respectively corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road chain, the action range information of the target speed limit sign is determined. In this way, the action range of the determined target speed limit sign can be made more reasonable, thereby contributing to improving driving safety.

[0051] In some embodiments, the action range information of the speed limit sign includes the speed limit value. Among them, determining the target speed limit sign of the first road chain based on the action range information respectively corresponding to multiple speed limit signs includes: determining the speed limit sign with a speed limit value lower than the first threshold as the target speed limit sign based on the speed limit values respectively corresponding to multiple speed limit signs.

[0052] Here, the first threshold can be set or adjusted according to actual situations such as safety requirements or scenario requirements.

[0053] For example, the speed limit signs are divided into two categories, one is the general speed limit sign, and the other is the target speed limit sign; if the speed limit value of the general speed limit sign is greater than or equal to X, then the first threshold is less than X.

[0054] In this way, determining the speed limit sign with a speed limit value lower than the first threshold as the target speed limit sign helps to clarify the action range of this type of target speed limit sign, thereby contributing to improving the rationality of the overall speed limit on the road chain and enhancing driving safety.

[0055] In some embodiments, the action range information of the speed limit sign includes the action distance. Among them, determining the target speed limit sign of the first road chain based on the action range information respectively corresponding to multiple speed limit signs includes: determining the speed limit sign with an action distance value lower than the second threshold as the target speed limit sign based on the action distance values respectively corresponding to multiple speed limit signs.

[0056] Here, the second threshold can be set or adjusted according to actual situations such as safety requirements or temporary construction needs, etc.

[0057] For example, speed limit signs are divided into two categories, one is the general speed limit sign, and the other is the target speed limit sign; if the action distance of the general speed limit sign is greater than or equal to Y, then the second threshold is less than Y.

[0058] Another example, if the speed limit sign has a clear action distance and this action distance is less than the shortest action distance Z, then the second threshold is less than or equal to Z.

[0059] In this way, determining the speed limit signs with action distances lower than the second threshold as target speed limit signs helps to clarify the action range of such target speed limit signs, thereby helping to improve the rationality of speed limits on the road chain and enhancing driving safety.

[0060] In some embodiments, when the action range of the target sign does not meet the preset conditions, combining the action range information corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road chain to adjust the action range of the target sign to obtain the target action range information of the target speed limit sign, including: obtaining the action distance and speed limit value included in the action range of the target speed limit sign; when the action distance corresponding to the target speed limit sign does not meet the preset first shortest action distance requirement, combining the speed limit values corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road chain to adjust the action distance and / or speed limit value in the action range of the target speed limit sign; based on the adjusted action distance and / or speed limit value of the target speed limit sign, determining the target action range information of the target speed limit sign. Further, when the action distance corresponding to the target speed limit sign meets the preset first shortest action distance requirement, the action range of the target speed limit sign is not adjusted.

[0061] Here, the action range of the target sign refers to the action range information indicated on the target speed limit sign. For example, Figure 2 the speed limit value shown in [reference] is 80 km / h and the action distance is 4374 meters. Another example, Figure 3 the speed limit value of the physical sign in [reference] is 30 km / h.

[0062] Here, the preset first shortest action distance requirement can be set with reference to the minimum length standard of the speed limit area. Exemplarily, Table 1 shows the corresponding relationship between the speed limit value and the minimum length of the speed limit area.

[0063]

[0064]

[0065] Table 1

[0066] It can be understood that the values shown in Table 1 can be set or adjusted according to the minimum safety standard or the desired safety standard.

[0067] It should be noted that different first shortest action distance requirements can be adopted for different road scenarios.

[0068] In some embodiments, when the action range of the target sign does not meet the preset conditions, the action range of the target sign is adjusted by combining the action range information corresponding to the previous speed limit sign and the next speed limit sign on the first road chain of the target speed limit sign, and the target action range information of the target speed limit sign is obtained, including: when the distance between the end position of the target speed limit sign and the start position of the next speed limit sign of the target speed limit sign does not meet the second shortest action distance requirement, the speed limit values corresponding to the previous speed limit sign and the next speed limit sign on the first road chain of the target speed limit sign are combined to adjust the action distance and / or speed limit value in the action range of the target speed limit sign; based on the adjusted action distance and / or speed limit value of the target speed limit sign, the target action range information of the target speed limit sign is determined.

[0069] Here, the preset second shortest action distance requirement can also be set with reference to the minimum length standard of the speed limit area as shown in Table 1. It should be noted that different second shortest action distance requirements can be adopted for different road scenarios.

[0070] In some embodiments, when the action range of the target sign does not meet the preset conditions, the action range of the target sign is adjusted by combining the action range information corresponding to the previous speed limit sign and the next speed limit sign on the first road chain of the target speed limit sign, and the target action range information of the target speed limit sign is obtained, including: when the action distance corresponding to the target speed limit sign does not meet the preset first shortest action distance requirement, the speed limit value of the target speed limit sign is compared with the speed limit value of the previous speed limit sign. If the speed limit value of the target speed limit sign is lower than the speed limit value of the previous speed limit sign, and the absolute value of the difference between the speed limit value of the target speed limit sign and the speed limit value of the previous speed limit sign is greater than the first preset value, and at the same time the speed limit value of the target speed limit sign is lower than the speed limit value of the next speed limit sign, and the absolute value of the difference between the speed limit value of the target speed limit sign and the speed limit value of the next speed limit sign is greater than the second preset value, then the action distance corresponding to the target speed limit sign is extended from the action distance to the starting point of the next speed limit sign, and the target action range information of the target speed limit sign is obtained based on the adjusted action distance.

[0071] In some embodiments, when the effective range of the target speed limit sign does not meet the preset conditions, the effective range of the target speed limit sign is adjusted by combining the effective range information corresponding to the previous speed limit sign and the next speed limit sign on the first road chain, and the target effective range information of the target speed limit sign is obtained, including: when the distance between the end position of the target speed limit sign and the start position of the next speed limit sign of the target speed limit sign does not meet the requirement of the preset second shortest effective distance, comparing the speed limit value of the target speed limit sign with the speed limit value of the previous speed limit sign; if the speed limit value of the target speed limit sign is lower than the speed limit value of the previous speed limit sign, and the absolute value of the difference between the speed limit value of the target speed limit sign and the speed limit value of the previous speed limit sign is greater than the first preset value, and at the same time the speed limit value of the target speed limit sign is lower than the speed limit value of the next speed limit sign, and the absolute value of the difference between the speed limit value of the target speed limit sign and the speed limit value of the next speed limit sign is greater than the second preset value, then the effective distance corresponding to the target speed limit sign is extended from the original effective distance to the starting point of the next speed limit sign, and the target effective range information of the target speed limit sign is obtained based on the adjusted effective distance; or, the speed limit value of the section between the original end position of the target speed limit sign and the start position of the next speed limit sign of the target speed limit sign is set to the target speed limit value, the target speed limit value is higher than the speed limit value of the target speed limit sign but lower than the speed limit value of the previous speed limit sign, and the target speed limit value and the section between the original end position of the target speed limit sign and the start position of the next speed limit sign of the target speed limit sign at least meet the requirement of the second shortest effective distance, and the target effective range information of the target speed limit sign is obtained based on the target speed limit value and the adjusted effective distance.

[0072] For example, Figure 4 shows a schematic diagram of road chain 1. As Figure 4 shown, the road chain 1 includes sections A1, A2, A3 and A4. The road chain 1 has a general speed limit sign of 100 km / h located in section A1, a target speed limit sign of 40 km / h located in section A2, and a general speed limit sign of 80 km / h located in section A4, and there is no speed limit sign in section A3. Generally speaking, after the effective distance of the target speed limit sign ends but before entering the range of the next speed limit sign, the speed limit value of the previous speed limit sign, that is, 100 km / h, is restored. Since the distance of section A3 is 50 m, which is less than the shortest effective distance of 2 km in Table 1, the effective distance of the target speed limit sign is adjusted to the next speed limit sign. The specific adjustment result is as Figure 5 shown, that is, in section A3, the speed of 100 km / h is not restored, but the speed limit continues to be 40 km / h, avoiding the Figure 4 high-low-high speed phenomenon in sections A1, A2 and A3 of

[0073] For example, Figure 6 a schematic diagram of road link 2 is shown, as Figure 6 shown, the road link 2 includes road sections B1, B2, B3, and B4. On the road link 2, there is a general speed limit sign of 80 km / h located on road section B1, a target speed limit sign of 30 km / h located on road section B2, and a general speed limit sign of 50 km / h located on road section B4. There is no speed limit sign on road section B3. Generally speaking, after the action distance of the target speed limit sign ends but before entering the range of the next speed limit sign, the speed limit value of the previous speed limit sign, that is, 80 km / h, is restored. Since the distance of road section B3 is 30 m, which is less than the shortest action distance of 0.8 km in Table 1, the action distance of the target speed limit sign is adjusted to the next speed limit sign. The specific adjustment result is as Figure 7 shown, that is, on road section B3, the speed of 80 km / h is not restored, but the speed limit continues to be 30 km / h, avoiding the occurrence of Figure 6 the low-high-low speed phenomenon on road sections B2, B3, and B4 in , which helps to improve the rationality of speed assignment and further helps to enhance driving safety.

[0074] In this way, when the action distance corresponding to the target speed limit sign does not meet the preset shortest action distance requirement, by combining the action range information corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road link, the action range of the target speed limit sign is determined, which can improve the rationality of speed limit assignment and further helps to enhance driving safety.

[0075] In some embodiments, when the action range of the target sign does not meet the preset conditions, by combining the action range information corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road link, the action range of the target sign is adjusted to obtain the target action range information of the target speed limit sign, including: combining the action range of the target speed limit sign, and the speed limit values corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road link respectively, to determine the reasonable action range of the target speed limit sign; when the action range is different from the reasonable action range, based on the reasonable action range, the target action range information of the target speed limit sign is determined.

[0076] For example, the original action range information of the target speed limit sign is x = x0, y = y0; the speed limit value of the previous speed limit sign is x = x1, and the speed limit value of the next speed limit sign is x = x2. By comparing the magnitudes and differences among x1, x2, and x0, the target action range information of the target speed limit sign is determined as x = x0', y = y0'.

[0077] In this way, first determine the reasonable action range of the target speed limit sign, and then compare the reasonable action range with the original action range, so that the finally set action range meets the rationality requirements, which can greatly improve the rationality of speed limit and further contribute to improving driving safety.

[0078] In some embodiments, the information processing method may further include: when switching from the first road chain to the second road chain, determining the action range of the first speed limit sign in the second road chain based on the action range information of the last speed limit sign in the first road chain.

[0079] For example, the first road chain includes 8 speed limit signs, among which there are 3 target speed limit signs, and the last speed limit sign is a general speed limit sign with a speed limit value of x8; the second road chain includes 3 speed limit signs, and its first speed limit sign is a general speed limit sign with a speed limit value of y1. Adjust the speed limit value y1 of the first speed limit sign in the second road chain according to the speed limit value x8 of the last speed limit sign in the first road chain, so that the speed limit value of the first speed limit sign is y1'.

[0080] Another example, the first road chain includes 5 speed limit signs, among which there are 2 target speed limit signs, and the last speed limit sign is a target speed limit sign with a speed limit value of x5; the second road chain includes 6 speed limit signs, and its first speed limit sign is a general speed limit sign with a speed limit value of y1. Adjust the speed limit value y1 of the first speed limit sign in the second road chain according to the speed limit value x5 of the last speed limit sign in the first road chain, so that the speed limit value of the first speed limit sign is y1'; or, move the starting position of the speed limit value y1 of the first speed limit sign in the second road chain backward by a certain distance.

[0081] In this way, the speed transition between the first road chain and the second road chain can be made smoother, and the safety of the transition area between the first road chain and the second road chain can be improved.

[0082] In the above solution, the information processing method may further include:

[0083] Aggregate roads with the same name within the preset area range, or different roads with the same traffic capacity and traffic smoothness greater than the set value into the same road chain.

[0084] Here, the preset area range can be set or adjusted according to actual situations such as user needs or road planning needs. For example, the preset area range can be divided by the area where the street is located or the area where the town is located or the area where the county is located, etc.

[0085] Here, the same traffic capacity can be understood as the same number of traffic lanes.

[0086] Here, the traffic smoothness can be represented by the angle between the first road and the second road. The larger the angle between the roads, the greater the traffic smoothness.

[0087] Here, the set value can be set or adjusted according to actual situations such as speed requirements or safety requirements.

[0088] Figure 8 A schematic diagram of a road chain is shown. Starting from Figure 8 It can be seen that the traffic smoothness between Road 1 and Road 3 is greater than that between Road 2 and Road 3, and Road 1 and Road 3 can be aggregated into the same road chain.

[0089] In this way, by aggregating to obtain a road chain, and then setting or adjusting the action range of the target speed limit sign in units of the road chain in terms of the extension of the speed limit value, the speed limit value on the entire road chain can be made more reasonable, which helps to improve the driving safety on this road chain, and further helps to improve the driving experience and riding experience.

[0090] In the above solution, after determining the target action range information of the target speed limit sign, store the target action range information of the target speed limit sign; or, generate and store the action range information of all speed limit signs included in the entire road chain according to the action range information of non-target speed limit signs and the target action range information of the target speed limit sign, so as to provide the action range information of all speed limit signs included in the entire road chain to vehicles or navigation devices, to assist manual driving or provide a basis for autonomous driving vehicles.

[0095] In some embodiments, the action range information includes a speed limit value. The determining module 920 is configured to:

[0101] When the action distance corresponding to the target speed limit sign does not meet the first minimum action distance requirement, or the distance between the end position of the target speed limit sign and the start position of the next speed limit sign of the target speed limit sign does not meet the second minimum action distance requirement, adjust the action distance and / or speed limit value in the action range of the target speed limit sign by combining the speed limit values respectively corresponding to the previous speed limit sign and the next speed limit sign of the target speed limit sign on the first road chain;
