For example, mobile devices include, but are not limited to: vehicle-mounted terminal, navigation equipment. As shown in fig. 1, the information processing method includes:

Here, the speed limit sign includes, but is not limited to, several types of high speed limit signs, low speed limit signs, and speed limit removal signs, and the speed limit sign is mainly used on expressways and urban roads.

Here, the action range information includes at least one of a speed limit value and an action distance.

Fig. 2 shows a schematic diagram of a speed limit sign with a clear range, and as can be seen from fig. 2, the speed limit sign in fig. 2 has a clear range of 4374 meters. Fig. 3 shows the speed limit sign having a definite scene, and as can be seen from fig. 3, the speed limit sign in fig. 3 has a definite scene, such as school, whose speed limit value is 30 km/h.

In some embodiments, obtaining the action range information corresponding to each of the plurality of speed limit signs of the first link includes: and acquiring the speed limit signs included in the first link and action range information corresponding to each speed limit sign from the database based on the identification information of the first link.

The method and the device do not limit how the database obtains the speed limit signs included in the first road link and the action range information corresponding to each speed limit sign.

Therefore, the action range information corresponding to the plurality of speed limit signs of the first link can be quickly acquired, and guarantee is provided for subsequently and quickly determining the target speed limit signs and the action range information thereof.

In some embodiments, the obtaining of the action range information corresponding to each of the plurality of speed limit signs of the first link includes: and acquiring images about the speed-limiting signs on the first road link through a satellite or other image acquisition equipment based on the track information of the first road link, and obtaining the speed-limiting signs included in the first road link and action range information corresponding to each speed-limiting sign based on the image analysis condition.

Therefore, the speed-limiting signs which are in accordance with the actual conditions of the current speed-limiting sign on the first road link and the action range information which corresponds to the speed-limiting signs respectively can be obtained, the target speed-limiting sign and the action range information of the target speed-limiting sign are adapted to the current road condition and the speed-limiting sign, and the rationality of the action range of the target speed-limiting sign is improved.

Here, the target acting range information of the target speed limit sign includes a speed limit value and/or an acting distance of the target speed limit sign.

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

It should be noted that different scenes may correspond to different preset conditions. The same scene may correspond to one or more preset conditions.

The preset conditions are not compulsorily limited in the disclosure, and the specific preset conditions can be set or adjusted according to the type of the scene or the user requirements.

According to the technical scheme, the target speed-limiting sign of the first road link is determined according to the action range information corresponding to the speed-limiting signs of the first road link; and then the action range information of the target speed limit sign is determined 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, so that the action range of the determined target speed limit sign is more reasonable, and the driving safety is improved.

In some embodiments, the action range information of the speed limit sign includes a speed limit value, wherein determining the target speed limit sign of the first link based on the action range information corresponding to each of the plurality of speed limit signs includes: and determining the speed limit signs with the speed limit values lower than the first threshold value as target speed limit signs based on the speed limit values corresponding to the plurality of speed limit signs respectively.

Here, the first threshold may be set or adjusted according to actual conditions such as security requirements or scene requirements.

For example, the speed limit signs are classified into two major types, one is a general speed limit sign, and the other is a target speed limit sign; if the speed limit value of the general speed limit sign is greater than or equal to X, the first threshold value is less than X.

Therefore, the speed limit sign with the speed limit value lower than the first threshold value is determined as the target speed limit sign, the action range of the target speed limit sign is facilitated to be determined, the reasonability of the overall speed limit on a road link is facilitated to be improved, and the driving safety is improved.

Here, the second threshold value may be set or adjusted according to actual conditions such as safety requirements or temporary construction requirements.

For example, the speed limit signs are classified into two major types, one is a general speed limit sign, and the other is a target speed limit sign; if the action distance of the general speed limit sign is greater than or equal to Y, the second threshold value is smaller than Y.

For another example, if the speed limit sign has a definite range and the range is less than the shortest range Z, the second threshold is less than or equal to Z.

Therefore, the speed limit signs with the action distance lower than the second threshold value are determined as the target speed limit signs, the action range of the target speed limit signs is facilitated to be determined, the reasonability of speed limit on a road link is facilitated to be improved, and the driving safety is improved.

In some embodiments, when the action range of the target speed-limiting sign does not satisfy the preset condition, the action range of the target speed-limiting sign is adjusted by combining action range information respectively corresponding to a previous speed-limiting sign and a next speed-limiting sign of the target speed-limiting sign on the first link, so as to obtain the target action range information of the target speed-limiting sign, including: acquiring the action distance and the speed limit value included in the action range of the target speed limit sign; under the condition that the action distance corresponding to the target speed limit sign does not meet the preset first shortest action distance requirement, the action distance and/or the speed limit value in the action range of the target speed limit sign are adjusted by combining the speed limit values respectively corresponding to the last speed limit sign and the next speed limit sign of the target speed limit sign on the first road link; and determining the target action range information of the target speed limit sign based on the adjusted action distance and/or speed limit value of the target speed limit sign. Further, under the condition that 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.

Here, the action range of the target speed limit sign means action range information indicated on the target speed limit sign, for example, the speed limit value shown in fig. 2 is 80km/h and the action distance is 4374 meters. As another example, the speed limit value of the physical sign in FIG. 3 is 30 km/h.

Here, the preset first shortest acting distance requirement may be set with reference to the minimum length criterion of the speed limit zone. Illustratively, table 1 shows the correspondence between the speed limit value and the minimum length of the speed limit zone.

In some embodiments, when the action range of the target speed-limiting sign does not satisfy the preset condition, the action range of the target speed-limiting sign is adjusted by combining action range information respectively corresponding to a previous speed-limiting sign and a next speed-limiting sign of the target speed-limiting sign on the first link, so as to obtain the target action range information of the target speed-limiting sign, including: under the condition that the distance between the ending position of the target speed limit sign and the starting position of the next speed limit sign of the target speed limit sign does not meet the requirement of the second shortest action distance, the action distance and/or the speed limit value in the action range of the target speed limit sign are adjusted by combining the speed limit values respectively corresponding to the last speed limit sign and the next speed limit sign of the target speed limit sign on the first link; and determining the target action range information of the target speed limit sign based on the adjusted action distance and/or speed limit value of the target speed limit sign.

Here, the preset second shortest operation distance requirement may also be set as in table 1 with reference to the speed limit zone minimum length criterion. It should be noted that different road scenes may use different second shortest range requirements.

In some embodiments, in the case that the action range of the target speed-limiting sign does not satisfy the preset condition, adjusting the action range of the target speed-limiting sign in combination with action range information respectively corresponding to a previous speed-limiting sign and a next speed-limiting sign of the target speed-limiting sign on the first link to obtain the target action range information of the target speed-limiting sign, including: under the condition that the distance between the ending position of the target speed limit sign and the starting position of the next speed limit sign of the target speed limit sign does not meet the requirement of the preset second shortest acting 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 value 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, meanwhile, the speed limit value of the target speed limit sign is lower than that of the next speed limit sign, the absolute value of the difference value between the speed limit value of the target speed limit sign and the speed limit value of the next speed limit sign is larger than a second preset value, extending the action distance corresponding to the target speed limit sign from the original action distance to the starting place of the next speed limit sign, and obtaining the target action range information of the target speed limit sign based on the adjusted action distance; or setting the speed limit value of the road section between the original ending position of the target speed limit sign and the starting position of the next speed limit sign of the target speed limit sign as the target speed limit value, wherein 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 road section between the original ending position of the target speed limit sign and the starting position of the next speed limit sign of the target speed limit sign at least meet the requirement of a second shortest action distance, and obtaining the target action range information of the target speed limit sign based on the target speed limit value and the adjusted action distance.

For example, fig. 4 shows a schematic diagram of a road link 1, as shown in fig. 4, the road link 1 comprises a road section a1, a road section a2, a road section A3 and a road section a4, the road link 1 comprises a general speed limit sign 100km/h located at the road section a1, a target speed limit sign 40km/h located at the road section a2 and a general speed limit sign 80km/h located at the road section a4, while there is no speed limit sign at the road section A3, generally speaking, after the action distance of the target speed limit sign is over and before the next limit sign range is entered, the speed limit value of the previous speed limit sign, namely 100km/h, is recovered, since the distance of the road section A3 is 50m, which is less than the shortest action distance 2km in table 1, the action distance of the target speed limit sign is adjusted to the next speed limit sign, and the specific adjustment result is shown in fig. 5, namely 100km/h is not recovered at the road section A3, but the speed is continuously limited at 40km/h, so that the high-low-high speed phenomenon of the road section A1, the road section A2 and the road section A3 in the figure 4 is avoided, the reasonability of speed assignment is improved, and the driving safety is improved.

For example, fig. 6 shows a schematic diagram of a road link 2, as shown in fig. 6, the road link 2 includes a road segment B1, a road segment B2, a road segment B3 and a road segment B4, the road link 2 includes a general speed limit sign 80km/h located at the road segment B1, a target speed limit sign 30km/h located at the road segment B2 and a general speed limit sign 50km/h located at the road segment B4, while there is no speed limit sign at the road segment B3, generally, after the action distance of the target speed limit sign is over and before the next limit sign range is entered, the speed limit value of the previous speed limit sign, i.e., 80km/h, is recovered, since the distance of the road segment B3 is 30m, which is less than the shortest action distance of 0.8km in table 1, the action distance of the target speed limit sign is adjusted to the next speed limit sign, and the specific adjustment result is shown in fig. 7, i.e., 80km/h is not recovered at the road segment B3, and the speed is continuously limited at 30km/h, so that the low-high-low speed phenomenon of the road section B2, the road section B3 and the road section B4 in the figure 6 is avoided, the reasonability of speed assignment is improved, and the driving safety is improved.

Therefore, under the condition that the action distance corresponding to the target speed limit sign does not meet the preset shortest action distance requirement, the action range of the target speed limit sign is determined by combining the action range information corresponding to the last speed limit sign and the next speed limit sign of the target speed limit sign on the first road link, the reasonability of speed limit assignment can be improved, and the driving safety is further improved.

In some embodiments, when the action range of the target speed-limiting sign does not satisfy the preset condition, the action range of the target speed-limiting sign is adjusted by combining action range information respectively corresponding to a previous speed-limiting sign and a next speed-limiting sign of the target speed-limiting sign on the first link, so as to obtain the target action range information of the target speed-limiting sign, including: determining a reasonable action range of the target speed limit sign by combining the action range of the target speed limit sign and 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 link; and under the condition that the action range is different from the reasonable action range, determining the target action range information of the target speed limit sign based on the reasonable action range.

For example, the original action range information of the target speed limit sign is x-x 0, and y-y 0; the speed limit value of the previous speed limit sign is x-x 1, the speed limit value of the next speed limit sign is x-x 2, and the target action range information of the target speed limit sign is determined to be x-x 0 'and y-y 0' by comparing the sizes and the differences among x1, x2 and x 0.

Therefore, the reasonable action range of the target speed limit sign is determined firstly, and then the reasonable action range is compared with the original action range, so that the finally set action range meets the rationality requirement, the rationality of the speed limit can be greatly improved, and the driving safety is further improved.

In some embodiments, the information processing method may further include: and under the condition of switching from the first road link to the second road link, determining the action range of the first speed-limiting sign in the second road link based on the action range information of the last speed-limiting sign in the first road link.

For example, the first road chain includes 8 speed limit signs, of which there are 3 target speed limit signs, and the last speed limit sign is a general speed limit sign, and the speed limit value is x 8; the second road chain comprises 3 speed limit signs, wherein the first speed limit sign is a common speed limit sign, the speed limit value is y1, and the speed limit value y1 of the first speed limit sign in the second road chain is adjusted according to the speed limit value x8 of the last speed limit sign of the first road chain, so that the speed limit value of the first speed limit sign is y 1'.

For another example, the first road chain includes 5 speed limit signs, of which there are 2 target speed limit signs, and the last speed limit sign is a target speed limit sign, and the speed limit value is x 5; the second road chain comprises 6 speed limit signs, wherein the first speed limit sign is a common speed limit sign, the speed limit value is y1, and the speed limit value y1 of the first speed limit sign in the second road chain is adjusted according to the speed limit value x5 of the last speed limit sign of the first road chain, so that the speed limit value of the first speed limit sign is y 1'; or, the starting position of the speed limit value y1 of the first speed limit sign in the second link is adjusted and then shifted by a certain distance.

Therefore, the speed transition of the first road chain and the second road chain can be smoother, and the safety of the transition area of the first road chain and the second road chain can be improved.

In the foregoing solution, the information processing method may further include:

and aggregating roads with the same name in the preset area range or roads with different names, which have the same traffic capacity and the traffic smoothness degree larger than a set value, into the same road chain.

Here, the preset area range may be set or adjusted according to actual conditions, such as user requirements or road planning requirements. For example, the preset area range may be divided into an area where a street is located, an area where a town is located, an area where a county is located, and the like.

Here, the same traffic capacity means the same number of traffic lanes.

Here, the degree of smoothness of the passage may be represented by an angle between the first road and the second road, and the greater the angle between the roads, the greater the degree of smoothness of the passage.

Here, the set value may be set or adjusted according to actual conditions such as speed requirements or safety requirements.

Fig. 8 shows a schematic diagram of a link, and as can be seen from fig. 8, the smoothness of the roads 1 and 3 is greater than the smoothness of the roads 2 and 3, and the roads 1 and 3 can be combined into the same link.

Therefore, the road chain is obtained through aggregation, and the action range of the target speed limit sign is set or adjusted by taking the road chain as a unit in the aspect of extension of the speed limit value, so that the speed limit value on the whole road chain is more reasonable, the driving safety on the road chain is improved, and the driving experience and the riding experience are improved.

In the scheme, after the target action range information of the target speed limit sign is determined, the target action range information of the target speed limit sign is stored; or generating and storing the action range information of all the speed limit signs included in the whole road chain according to the action range information of the non-target speed limit signs and the target action range information of the target speed limit signs, so as to provide the action range information of all the speed limit signs included in the whole road chain for vehicles or navigation equipment, and assist manual driving or provide driving basis for automatic driving vehicles.
