The embodiments of the present application will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic diagram illustrating a scenario in which the embodiment of the present application is applicable, and as shown in fig. 1, there may be one or more data acquisition devices and may further include an information acquisition device. The data acquisition device may be a terminal device, for example, the data acquisition device may be the vehicle 101, the roadside unit 102, and the vehicle 103 in fig. 1, and may also be a component, a module, or a chip in these devices. When the data acquisition device is a terminal device or a component or chip arranged in the terminal device, the vehicle information in the road can be acquired through a sensor of the terminal device. The data acquisition device may directly report the acquired first roadside vehicle information to the information acquisition device, or may report the information to the information acquisition device through other equipment, for example, the information may be sent to the information acquisition device through the third party cloud 104. The third party cloud 104 may be other servers or devices.

In the embodiment of the present application, the information obtaining apparatus may be a terminal device or a server in the cloud, or a component or a chip in these devices, and is illustrated in fig. 1 by taking an example in which the information obtaining apparatus is disposed on the server 110 in the cloud. The information acquisition device in the embodiment of the application receives the vehicle information acquired by the at least one data acquisition device, and through statistical analysis, the information of the parking condition of the vehicle on the first road side of the first road section in the first time period can be acquired.

The first parking information may be used to assist the user in intelligent driving. For example, the user may be assisted in path planning. For example, the planned route may be issued to an electronic device or a vehicle of the user to provide a navigation service. The electronic device may be, for example, the electronic device 113 in fig. 1 (fig. 1 is merely an example of a smart phone, and in practical applications, the electronic device includes, but is not limited to, a tablet computer, a smart band, a smart watch, and the like having a display screen).

In the second way, the road between two adjacent intersections may be referred to as a road segment, in which case the lengths of the two road segments may be equal or may not be equal. In this way, whether the road needs to be bypassed can be determined according to the road occupation degree of the vehicles parked on the road between two adjacent intersections.

In a third way, the road between two intersections can be called a road segment, the two intersections can be adjacent intersections or nonadjacent intersections, and the absolute value of the difference between the length of a road segment and the preset length can be required to be not more than the preset distance threshold, so that the road segment can be divided by the intersections, and the length of each road segment can be close to the preset length.

A road segment can also be understood as a spatial statistical unit, and the first time clustering analysis is performed on the roadside parked vehicles in the spatial statistical unit, so as to obtain first parking information.

Further, the information acquisition means may determine the width of the road surface occupied by the vehicle in combination with the width information of the vehicle, the position information of the vehicle, and the road width information of the first road section.

It should be noted that the roadside parked vehicle mentioned in the embodiments of the present application refers to a vehicle parked on the side of a road. When the vehicle is not parked on the side of the road, the road on the side of the road can be used for passing the vehicle; when the vehicle is parked on the side of the road, the width of the road available for the vehicle to pass through becomes narrower. The road side can be provided with the parking stall in this application embodiment, also can not set up the parking stall, and a roadside parked vehicle in this application embodiment can be for the vehicle of parking in the roadside parking stall, also can be for the vehicle of parking in the roadside parking stall (for example because near do not have the parking stall, or because parking in the roadside that leads to of interim short time).

S303, the information acquisition device determines the information of the vehicle parking condition on the first road side in the first time period of the first road side according to the vehicle information of at least one vehicle on the first road side.

For convenience of description, in the embodiments of the present application, information of a parking condition of a vehicle on the first road side in the first time period of the first road side is referred to as first parking information. The first parking information may be used to plan a target path between the source address and the target address.

The information acquisition device in the embodiment of the present application may refresh the information of the parking condition of the vehicle on the first road side for a plurality of times periodically or with an indefinite duration, and the first parking information is taken as an example to introduce the information of the parking condition of the vehicle on the first road side generated in the embodiment of the present application.

In a possible embodiment, the first parking information may include at least one of the following information a1 to information a 5:

information a1, identification of the first road side.

The identification of the first road side may be a name, such as a road name, for the first road segment on the map.

In yet another possible embodiment, the identification of the first road side may also be the name of a certain area, place or object on the first road side. For example, a roadside parking space is arranged on the first roadside, and the identifier of the first roadside may be an area identifier of a roadside parking space area. The area identification of the roadside parking space area may be named manually, such as may be named by a government department, or may be named by the manager of the roadside parking space area.

Information a2, position information of the first road side.

The position information of the first road side may be information capable of indicating a start position, an end position, and a road where the first road side passes, and may further include information identifying which road side the first road side is in the first road section (the first road side may refer to two road sides in the first road section, and may also refer to any one of the two road sides in the first road section). For example, the first road segment is a road segment between two intersections, and the position information of the first road side may include position information of the two intersections.

In yet another possible embodiment, the position information of the first roadside may also be position information of a certain area on the first roadside, such as a roadside parking space is provided on the first roadside, and the position information of the first roadside may be position information of a roadside parking space area in the first roadside, such as position information of two end points of the roadside parking space area.

Information a3, first time period.

For example, the information of the parking situation of the vehicle on the first road side may be periodically refreshed, such as every 10 minutes. To be more practical, the refresh period may be set to the minute level. For example, the information of the parking condition of the vehicle on the first road side is generated at 8 o ' clock, for example, the parking condition of the vehicle on the first road side from 8 o ' clock to 8 o ' clock and 10 o ' clock can be determined by analyzing the environmental information of the first road side reported by the data acquisition device from 8 o ' clock to 8 o ' clock and 10 o ' clock.

And information a4, holiday information corresponding to the first parking information.

The holiday information corresponding to the first parking information can assist in analyzing the law of the parked vehicles on the first road side, so that the information of the parking conditions of the vehicles on the first road side can be well predicted.

Information a5, credibility information.

The credibility information is used for representing the credibility of the first parking information. The credibility information may be at least one of the following information a5-1 or information a5-2, for example.

Information a5-1, the time of generation of the first parking information.

In one possible embodiment, when the first parking information is closer to the current time during the route planning, the more the first parking information is estimated to match the actual situation of the first road side, and the higher the possibility of being informed during the route planning. When the path planning is carried out, the farther the first parking information is away from the current time, the less the first parking information is not in accordance with the actual situation of the current first road side, and the lower the possibility of being picked up during the path planning process.

Information a5-2, the refresh frequency of the first parking information, wherein the first parking information is periodically refreshed.

In practical application, because roadside parking has a disorder property, in a possible implementation manner, in the embodiment of the present application, information of a parking condition of a vehicle on a first road side may be periodically refreshed, and the higher the refreshing frequency is, the more the first parking information conforms to a current actual condition of the first road side, and the higher the possibility of being trusted during a path planning process is. The lower the refresh frequency, the less the first parking information is presumed to be in accordance with the current actual situation of the first road side, and the lower the probability of being picked up during the path planning process.

In a further possible embodiment, the first parking information may further comprise at least one of the following information b1 or information b 2:

and information b1 that is road width occupancy information of a vehicle parked on the first road side.

The road surface width occupancy information indicates a width of a road surface occupied by the vehicle parked on the first road side.

For example, for a vehicle parked at the first road side, the information obtaining device may determine the width information of the vehicle according to an image including the vehicle. Further, the information acquisition means may determine the width of the road surface occupied by the vehicle in combination with the width information of the vehicle, the position information of the vehicle, and the road width information of the first road section.

Further, the information acquisition device determines road surface width occupation information according to the road surface width occupied by the at least one vehicle on the first road side. For example, if 3 vehicles are parked on the first road side, and the road widths occupied by the 3 vehicles are 2 meters, 1.8 meters, and 1.8 meters, respectively, the value occupying the largest road width may be selected as the road width occupation information, 1.8 meters occupying the largest of the 3 road widths may be selected as the road width occupation information, or the average value of the 3 road widths may be selected as the road width occupation information.

In yet another possible embodiment, the road surface width occupation information may also be used to indicate the width of the road surface of the road left on the first road section available for traffic, for example, the width of the road surface occupied by the parked vehicles on both road sides may be subtracted from the total width of the road surface of the road available for traffic on the first road section, and the obtained value may be the road surface width occupation information.

It should be noted that, in this embodiment of the present application, the first road side refers to a road side in the first road segment, and may refer to two road sides in the first road segment, and the road surface width occupation information of the vehicle on the first road side may include a total road surface width occupied by vehicles parked on the two road sides in the first road segment. Or the first road side refers to any one of two road sides on the first road section, in which case the road surface width occupation information of the vehicle on the first road side may include the road surface width occupied by the vehicle parked on the first road side in the first road section.

And information b2, which is information on the degree of occupation of the road on the first road section by the vehicle parked on the first road side.

For example, several occupancy level information may be preset, for example, the following may be set in sequence according to the order of occupancy levels from low to high: no occupancy, light occupancy, moderate occupancy, and heavy occupancy. The occupancy information of the roadside parked vehicles for the road of the first roadside may be determined according to at least one of:

the number of the first road side parked vehicles (which may be referred to as the number of first parked vehicles and may be obtained by statistics according to vehicle information), the length of the first road side, the width of the first road section, or road surface width occupation information.

The following are a few examples of how occupancy information may be determined:

in an example I, a corresponding relation between the number of the roadside parked vehicles and the occupation degree information is set, and then the occupation degree information of the corresponding roadside parked vehicles on the road is determined according to the corresponding relation and the number of the first roadside parked vehicles. The number of the roadside parked vehicles and the occupation degree information can be positively correlated, that is, the more the number of the roadside parked vehicles is, the higher the occupation degree of the roadside parked vehicles on the road section on the road is.

It should be noted that, in the embodiment of the present application, the first road side may refer to two road sides in the first road section, and in this case, the number of parked vehicles on the first road side may be understood as the total number of parked vehicles on the two road sides in the first road section. Or first road side means any one of the two road sides on the first road section, in which case the number of first road side parked vehicles may be understood as the total number of vehicles parked on the first road side in the first road section.

In the second example, an association relationship among the number of the roadside parked vehicles, the road length (or referred to as the roadside length), and the occupancy degree information is set, and then the occupancy degree information of the corresponding roadside parked vehicles on the road is determined according to the association relationship, the number of the first roadside parked vehicles and the length of the first road. The ratio between the number of roadside parked vehicles and the road segment length may be a positive correlation with the occupancy information.

In this case, when the lengths of the two road segments are different, if the number of the vehicles parked on the road sides of the two road segments is substantially equal, it is possible to determine the information of the degree of occupation of the road by the two different road-side parked vehicles. For example, a road between two adjacent intersections is referred to as a road segment, and the length of the road segment is twice that of another road segment, and the roadside of the two road segments is parked with the same number of vehicles, in this case, the occupation degree information of the roadside to the road segment by the parked vehicles on the roadside of the road segment with the longer length may be lightly occupied, and the occupation degree information of the roadside to the road segment by the parked vehicles on the roadside of the road segment with the shorter length may be moderately occupied.

In the third example, the corresponding relation between the road surface width occupation information and the occupation degree information is set, and then the corresponding occupation degree information is determined according to the corresponding relation and the road surface width occupation information of the first road side. The road width occupation information can indicate the road width occupied by the first road side parking vehicle, and the size and the occupation degree information can be in positive correlation, namely the wider the road width occupied by the first road side parking vehicle is, the higher the occupation degree of the road side parking vehicle on the road section is, and the lower the irregular condition is.

And example four, setting corresponding relations of the road surface width occupation information, the road section width and the occupation degree information, and then determining the corresponding occupation degree information according to the corresponding relations, the road surface width occupation information of the first road side and the width of the first road section. The road surface width occupation information and the width of the first road section can indicate the remaining road surface width of the first road section available for the running vehicles, and the size and the occupation degree information can be in inverse correlation, namely the wider the remaining road surface width available for the running vehicles, the lower the occupation degree of the road by the road-side parked vehicles on the road section is, and the higher the irregular degree is.

Example five, an association relationship between the number of roadside parked vehicles, the road length (or referred to as the roadside length), the road width occupation information, and the occupation degree information is set, and then according to the association relationship, the number of first roadside parked vehicles, the length of the first roadside, the width of the first road section, and the road width occupation information of the first roadside, the corresponding occupation degree information is determined.

In a further possible embodiment, the first roadside includes roadside parking spaces, in which case the first parking information may further include the following information c1: parking space information of a first roadside.

The information c1 may comprise at least one of the following information c1-1 or information c 2-2:

information c1-1, the number of free parking spaces in the first road side.

In a possible embodiment, the roadside parking space of the first roadside may include or lack an identification line of a parking space. When the identification line of the parking space exists, whether the parking space on the road side is occupied or free can be identified from the environmental information reported by the data acquisition device. And then can count out the quantity of idle parking stall in the first road side.

In yet another possible embodiment, the parking space may be selected based on the total number of parking spaces on the first roadside, and the total number of vehicles currently parked in the parking space area on the first roadside, which may be referred to as a second number of parked vehicles, the number of free parking spaces in the first road side is calculated. The total number of parking spaces on the first roadside may be preset or may be calculated according to the length of the first roadside.

Because the information of roadside parking stall does not have special server to manage and control like large-scale parking area, therefore roadside parking stall information has not been provided for the user all the time, and based on the information that data acquisition device reported, can generate the parking stall information of first roadside and provide for the user in this application embodiment to can provide the selection of more parking stalls for the user, improve user's convenience.

Information c1-2, a charging mode for roadside parking spaces in the first road side.

Optionally, the information c1 may further include other information, such as the total number of parking spaces in the roadside parking space area, and a reason description of the number of currently parked vehicles in the roadside parking space area. For example, the roadside parking space area is located near a school, all parking spaces in the roadside parking space area are free parking spaces in the time period, and a reason explanation, such as a cold and fake period, may be added.

In a possible embodiment, when the first road side comprises a roadside parking space, the first parking information may be used to assist the user in selecting a parking lot, in which case the first parking information may comprise at least one of the aforementioned information a1, information a2, information a3, information a4, information a5 or information c 1.

S304, the information obtaining device may plan a target path between the source address and the target address according to at least one of the first parking information, the predicted second parking information within the second time period, or at least one pre-stored third parking information.

In the embodiment of the present application, the first parking information and the second parking information are both information of parking situations of vehicles on the first road side, and the difference is: the first parking information is information of a latest vehicle parking condition on the first road side which is currently acquired. And the second parking information is information of the predicted parking situation of the vehicle on the first road side for the second period of time. The time starting point of the second time period is later than the time starting point of the first time period. The third parking information may be information of the parking condition of the vehicle on the first road side acquired before the first parking information is acquired, or may be preset information of the parking condition of the vehicle on the first road side, for example, the preset information of the parking condition of the vehicle on the first road side according to past experience, or the preset information of the parking condition of the vehicle on the first road side according to historical data.

In an embodiment of the application, the second parking information may be predicted according to at least one of the first parking information or at least one pre-stored third parking information. Several examples of possible predicted secondary parking information are presented below.

Example d1, the occupancy level information in the predicted second parking information is: occupancy level information in a third parking message.

For example, yesterday has a first road segment occupying degree of heavy occupancy in a second time period (illustratively, 5 to 7 pm. It can be predicted that the degree of occupancy of the first road segment by the roadside parked vehicles within the second time period in the future today (illustratively, 5 to 7 pm).

For another example, when yesterday is within the second time period, the number of the idle parking spaces in the first road side is 5. The number of the idle parking spaces on the first road side in the future second time period today can be predicted to be 5.

In a further possible embodiment, the third parking information is information of the parking situation of the vehicle on the first road side in the historical second time period, so that the accuracy of the predicted second parking information can be improved. For example, the first time period is 7: point 50-8, second time period 8: point 50-9, the first parking information is today 7: information on the parking condition of the vehicle on the first road side corresponding to the point 50-8. The second parking information is predicted today 8: information on the parking condition of the vehicle on the first road side corresponding to the point 50-9. The third parking information is 8 per day in the past at least one day: information on the parking condition of the vehicle on the first road side corresponding to the point 50-9.

It should be noted that, in the following description, the definition of the time period is referred to in the embodiments of the present application, for example, the first time period and the second time period may be equal or unequal, and are not particularly limited. The actual length of any one of the first time period and the second time period may be self-defined, for example, several minutes or several hours, which is not limited.

Example d2, the occupancy level information in the second parking information is: among the occupancy degree information in the plurality of third parking information: the largest one of the ratios.

For example, three pieces of third parking information corresponding to second time periods of yesterday, the previous day and the most previous day are obtained, and the three pieces of information respectively indicate that the occupation degree of the parked vehicle on the first road section is heavy occupation, heavy occupation and medium occupation in sequence. Because the heavy occupancy accounts for two thirds, the degree of occupancy of the roadside parked vehicles on the first road section in the second time period in the future today can be predicted to be also heavy occupancy.

For another example, three pieces of third parking information corresponding to the second time periods of yesterday, the previous day, and the most previous day are acquired, and the three pieces of information respectively indicate that the number of free parking spaces on the first roadside is sequentially 5, and 10. Since 5 takes up two thirds, it can be predicted that the number of free parking spaces on the first roadside in the second time period in the future today is 5.

In yet another possible embodiment, the number of free parking spaces for which future second parking information is predicted may be: the average value of the number of free parking spaces in the plurality of third parking information, or the weighted sum value. For example, the weight may be determined for each of the historical third parking information according to the recency of the date on which the third parking information was generated. Wherein the newer the date, the greater the weight of the third parking information may be. The weight of the third parking information is used to characterize its degree of influence on the number of free parking spaces in the second parking information.

Example d3, in one possible embodiment, the first parking information further comprises: and the holiday information corresponding to the first parking information. And the holiday information corresponding to the at least one piece of prestored third parking information is matched with the holiday information corresponding to the first parking information. Therefore, the information of the vehicle parking condition on the first road side in the future second time period can be predicted according to the road side parking rule of the holiday of the first road section, and the accuracy of the predicted second parking information is improved.

For example, if today is saturday, the third parking information corresponding to the second time period in the past saturday may be used for prediction. For example, the largest occupation degree information in the plurality of third parking information corresponding to the second time periods on the plurality of saturdays may be: occupancy level information in the second parking information.

For another example, if the current day is saturday, the third parking information corresponding to the second time period in the past saturday may be used for prediction. For example, the largest number of the first roadside empty parking spaces in the plurality of third parking information corresponding to the second time period in the plurality of saturdays may be taken as: the number of free parking spaces on the first road side in the second parking information.

Example d4, the second parking information is predicted in combination with the first parking information and the at least one third parking information.

Corresponding weights can be set for the first parking information and the third parking information, so that the occupation degrees in the first parking information and the third parking information are subjected to weighted addition calculation, and the predicted occupation degree in the second parking information can be obtained. For another example, the number of empty parking spaces in the first parking information and the third parking information may be calculated by weighted addition, so that the predicted number of empty parking spaces in the second parking information may be obtained.

It should be noted that, the content included in the predicted second parking information may refer to the content included in the aforementioned first parking information, and is not described herein again. The predicted second parking information may not carry the reliability information.

The information of the parking condition of the vehicle on the first road side in the embodiment of the present application may have various application scenarios, such as the following application scenario 1 and application scenario 2. In the application scenario 1, a target path is planned in combination with at least one of the first parking information, the second parking information, or the third parking information. In the application scenario 2, parking space information is provided for the user in combination with at least one of the first parking information, the second parking information, or the third parking information. The following are described separately.

And applying a scene 1 to plan a target path by combining at least one of the first parking information, the second parking information or the third parking information.

Several schemes for planning the path are described below by way of several examples.

Example e1, a target path is planned according to the first parking information and the third parking information.

For example, 10 pieces of third parking information are obtained, wherein the occupancy degree information in the 9 pieces of third parking information is heavy occupancy, and the occupancy degree information in the 1 piece of third parking information and the first parking information is light occupancy. In this case, since 9 of the 11 paths each indicate that the first route segment is occupied to a greater extent, which is nine tenths of a tenth, and is the largest, it may be determined that the first route segment belongs to a route segment that is frequently occupied, and thus, the first route segment may be avoided as much as possible, i.e., a route including the first route segment is not selected as the target route. In the embodiment of the application, the target path can be recommended to the user as a path with higher priority, so that the user has higher possibility of selecting and using the target path, and other paths which are not taken as the target path have lower priority, so that the user has lower possibility of selecting the target path. Therefore, in this example, since the route including the first link is screened out and is not taken as the target route, the user can avoid the first link as much as possible.

In one possible embodiment, one time in the second time period is a time of traveling along the first route from the source address to the first road side. For example, the driving from the source address to the destination address includes at least two paths, and the first path is a path including the first road segment in the at least two paths. The second time period may be a time period from the source address, traveling along the first route, and traversing the first road segment. For example, one time in the second time period is the time of travel along the first route from the source address to the first road segment.

For example, if the current time is 15 am and if it takes about 25 minutes to travel along the first route to the first link from the source address, the time to reach the first link is expected to be 9 o ' clock 40 minutes, and the second time period may be 9 o ' clock 40 to 9 o ' clock 50 minutes. The third parking information corresponding to the second historical time period and the first parking information can be used for evaluating whether the decision is made to avoid the path comprising the first road section or not, so that the accuracy of path planning can be improved.

It should be noted that, since the third parking information is information of the parking condition of the vehicle on the first road side generated in the past, the content included in the third parking information can be referred to the above-mentioned related description about the first parking information.

Example e2, a target path is planned according to the first parking information and the second parking information.

In a possible embodiment, corresponding weights may be set for the first parking information and the second parking information, and the first parking information and the second parking information are weighted and fused, and then it is determined whether the first road section needs to be avoided according to the result. The weight of the first parking information is used for representing the influence degree of the first parking information on the result, and the weight of the second parking information is used for representing the influence degree of the second parking information on the result.

In a possible embodiment, the weight may be set according to the third parking information of the first road segment history, for example, if the third parking information of the first road segment shows that the parked vehicles on the first road segment have strong regularity, the weight of the second parking information may be set to a large value. If the third parking information of the first road section shows that the vehicle parking on the first road section is irregular or the regularity is not obvious, or the third parking information has strong randomness, the weight of the first parking information can be set to be a large value.

In yet another possible embodiment, the weights of the first and second parking information may be made adjustable. Such as may be adjusted based on the trustworthiness information. The credibility information is used for representing the influence degree of the first parking information on the target path. For example, if the first parking information reliability information indicates that the reliability of the first parking information is low, such as the refresh frequency is low, and/or the generation time is far from the current time, the weight of the first parking information may be adjusted to be low, and correspondingly, the weight of the second parking information is adjusted to be high because the sum of the two weights is fixed, such as 1. If the refresh frequency of the first parking information is higher and/or the generation time is closer to the current time, the weight of the first parking information may be adjusted higher, and correspondingly, the weight of the second parking information is adjusted lower.

For example, the first parking information may be weighted 70% and the second parking information may be weighted 30%, the first parking information indicating that the roadside parked vehicle occupies the first road segment to a lesser extent during a first time period, and the second parking information indicating that the roadside parked vehicle occupies the first road segment to a greater extent during a second time period predicted to be in the future. Since the weight of the light occupancy is 70%, when the target route is screened, the first route segment does not need to be avoided, that is, the first route including the first route segment may be used as the target route if other factors are also suitable.

For another example, for example, the first parking information is generated at a long date, for example, 5 hours ago, and since the roadside parked vehicle has disorder property, the probability that the first parking information at 5 hours ago is consistent with the actual situation of the first road section in the second time period in the future is low, so the weight of the first parking information can be reduced, for example, the weight of the first parking information is reduced from 70% to 20%, and the weight of the second parking information is increased from 30% to 80%. And then planning a path according to the updated weight and the first parking information and the second parking information.

In addition to the two examples described above, there are other ways to plan the target path, such as planning the target path based on the first parking information, the second parking information, and the third parking information. In this embodiment, corresponding weights may be set for each parking information, so as to comprehensively consider whether the first road segment needs to be avoided. The related content in this manner can be referred to the aforementioned scheme, and is not described herein again.

Through the scheme, when the paths are screened, the road side can be selected as far as possible without parking vehicles, or the road side can park the road section with the vehicle occupying the road to a lighter degree, and the road side can be avoided as far as possible to park the road section with more vehicles, so that the passing time can be shortened, and the passing efficiency can be improved. On the other hand, since the roadside parked vehicles occupy a road with a certain width, the road is narrowed, and traffic accidents are easily caused, so that the occurrence frequency of the traffic accidents can be reduced if the roadside parked vehicles avoid such road sections during planning of the path.

When the information acquisition device filters the path, the information acquisition device can select the path according to one or more of the following elements besides the first parking information, so as to select a more reasonable target path:

road grade, congestion conditions, charging conditions, distance, number of traffic lights, user individual driving habits, user individual preferences, etc.

As can be seen from the above, in the embodiment of the present application, information of a parking condition of a vehicle on a roadside of a road segment on a map may be provided, and the information is dynamically variable and may also be referred to as dynamic information of a roadside parked vehicle (or referred to as a dynamic information model of the roadside parked vehicle). In the embodiment of the application, a dynamic information model of the roadside parked vehicle can be constructed, a dynamic map layer of the roadside parked vehicle can be generated (the map layer comprises first parking information of a first roadside which is refreshed recently), a prediction map layer of the roadside parked vehicle can be generated (the map layer comprises second parking information of a predicted road section), when path planning is carried out, the first parking information of the road section which is refreshed recently and the second parking information of the road section which is predicted can be used as two inputs, road sections with no parking at the roadside and fewer parked vehicles at the roadside can be selected preferentially, and therefore a user can avoid the road sections which are occupied by the roadside parked vehicle as much as possible.

And applying the scene 2, and providing roadside parking space information for the user by combining the first parking information, the second parking information or the third parking information.

The first parking information includes first roadside parking space information over a first time period. The second parking information also includes first roadside parking space information, and the second parking information is preset. The third parking information also includes parking space information of the first roadside, but the third parking information is the parking space information of the first roadside within the predicted future second time period. One time in the second time period may be a time of driving from the source address to the first road side.

In the embodiment of the application, when the user inputs the target address, the current position of the user can also be used as the target address, and the road side parking space information near the target address can be correspondingly provided. For example, a parking space on the first roadside is a parking space near the target address, and a distance between the parking space on the first roadside and the target address is smaller than a preset distance threshold. At least one of the first parking information, the second parking information, or the third parking information may be provided to the user for the user to decide whether to park the vehicle to a roadside parking space to the first roadside.
