Detailed Description
As described in the background art, in the application of electronic maps, it has become a trend to prompt users with road condition information, and the specific prompting manner may be various. The prompting may be made by voice, for example, or by other means, such as by road display colors, for example.
The prompt is generally a prompt for the overall road condition of the road. However, when a user drives on a road, for roads with different departure directions, the road conditions of lanes in the departure directions are different. If prompt is performed in advance according to a single road condition, the accuracy is poor.
In the embodiment of the invention, the multi-direction road condition of the current road is acquired in the navigation state, and the road condition information is prompted by combining the main direction and the multi-direction road condition. Because the multidirectional road conditions comprise the road conditions of different heading directions of the current road, and the main direction is the advancing direction of the navigation planning route on the current road, the road condition information can be prompted by combining the main direction and the multidirectional road conditions, the road conditions of the lanes needing to be driven by the vehicle can be prompted, and the road condition information is more accurate.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1 in combination, the road condition information prompting method in the embodiment of the present invention may include the following steps:
step S11, acquiring multidirectional road conditions of a current road from a server in a navigation state, wherein the multidirectional road conditions comprise road conditions of the current road in different output directions;
and step S12, carrying out road condition information prompt by combining a main direction and the multi-direction road condition, wherein the main direction is the advancing direction of the navigation planning route on the current road.
The current road is a road on which the vehicle runs currently, and the multi-direction road conditions comprise road conditions of lanes corresponding to different output directions of the current road.
In a specific implementation, the multidirectional road condition may be obtained from a server, and specifically, referring to fig. 2, the multidirectional road condition is implemented by the following steps:
step S21, sending a road condition updating request to a server, wherein the road condition updating request comprises the identification of the current road;
step S22, receiving the multidirectional road condition of the current road from the server in response to the road condition update request.
Referring to fig. 9 in combination, fig. 9 is a schematic view of an application scenario of a road condition information prompting method according to an embodiment of the present invention, where the application scenario may include a front end 91 and a server 92. In the navigation process, the front end 91 loaded in the vehicle may send a road condition Update request to the service side, that is, the server 92 of the map service provider, for example, the request may be an Estimated Time of Arrival Update (ETAU) request sent to the service side at regular Time, and the server 91 may send a multidirectional road condition to the front end 91 in response to the request of the front end 91, and specific implementation processes may be described later and are not described herein again.
The front end 91 may be various suitable intelligent devices for vehicle navigation, such as a mobile phone and a tablet computer, or may be a dedicated navigation device mounted on a vehicle, and the front end 91 may communicate with the server 92 to obtain information from the server 92. As described above, the server 92 is a server of a map service provider, and may be a single server or a server cluster, and may provide a map service to the front end 91 according to a scene requirement.
In a particular implementation, the identification of the current road may be an identification of a smallest unit (Link) of the navigation plan route. The multidirectional road conditions may include road conditions of different heading directions of a current road, and may be specifically represented as: the main action corresponding to the steering mode, namely the advancing direction of the navigation planning route on the current road; and auxiliary actions, i.e. actions other than the main action of the current road; the data list corresponding to the main action and one or more auxiliary actions may include road conditions of lanes of different actions.
In particular implementations, road conditions may be classified into different categories, such as congestion, slow-moving, and clear. The multi-directional road condition may include grades of lanes in different out-of-degree directions. In some scenarios, one degree-out lane road condition may include multiple segments at different levels, and in these scenarios, the multi-directional road condition may include the levels of the segments of the different degree-out lanes, as well as the lengths of the segments.
Referring to fig. 3 in combination, in one scenario, the Link included in the current road is identified as Link31, the current road is a road with a direction of excess degrees, and the links identified as Link32 and Link33 are both connected with the Link of the current road. Accordingly, the current road includes two lanes, namely Lane34 and Lane 35. The Lane34 is a Lane running straight to Link32, and the Lane35 is a Lane running right ahead to Link 33.
As previously described, the multi-directional road condition may include the levels of the respective segments of the lanes in different egress directions. In the above scenario, the multi-directional road condition may include the rank of Lane34 and Lane 35. The Lane34 may be smooth in grade, the Lane35 includes multiple segments with different grades, the road condition of the segment D36 is smooth, the road condition of the segment D37 is slow running, and the road condition of the segment D38 is congested.
Further, if the vehicle is actively driven as a straight-ahead driving, the corresponding Lane is Lane 34. Following the previous example, the data list corresponding to the main action going straight and the auxiliary action going to the right front may include: road conditions of Lane 34; the length of each segment in Lane35, and the corresponding rank of the different segments.
It can be understood that, after the front end receives the multidirectional road condition, other ways of obtaining the lengths of the segments in the lane are also within the protection scope, which is not limited to this. For example, following the previous example, the proportion of the total length of each segment in Lane35 may also be included.
In a specific implementation, the multi-directional road condition of the current road may be a multi-directional road condition of a Link where the vehicle is currently located, or may also include a Link where the vehicle is currently located and a multi-directional road condition of more links in the driving direction of the navigation planning route.
In one implementation, the multi-directional road conditions of the current road may be based on a current location of the vehicle, for example, the multi-directional road conditions within a preset range from the location of the vehicle may be requested from the server. Accordingly, the road condition update request may be a request for a multidirectional road condition within a preset range from the vehicle position.
Further, the preset range may be set according to a road class of the current road. For example, different preset ranges may be set for the highway and the express way. The specific preset range may be calculated in combination with the estimated vehicle speed corresponding to the road class.
After the front end receives the multidirectional road conditions of the current road, the road condition information can be prompted by combining the main direction and the multidirectional road conditions. Specifically, referring to fig. 4 in combination, the following steps may be included:
step S41, judging whether a preset prompt condition is met or not by combining the main direction and the multidirectional road condition;
and step S42, if the preset prompting conditions are met, prompting the road condition information.
Through the judgment of the preset conditions, when the preset prompt conditions are met, the prompt of the road condition information is carried out, so that excessive prompt can be avoided, and the user at the front end can be better experienced by proper prompt.
Further, the preset prompting condition may include one or more of the following: the output direction corresponding to the multidirectional road condition is consistent with the stored output direction; the road condition of the main direction is different from the road conditions of other directions in the multi-direction road condition.
The multidirectional road condition is received from the server, and the condition of error prompt can be avoided by comparing the output direction of the multidirectional road condition received from the server with the output direction of the current road in the map data stored at the front end.
By comparing the road condition of the main direction with the road conditions of other directions, when the main direction and the other directions are different, prompting is carried out, the prompting situation can be reasonably determined, and the prompting meets the requirements of front-end users.
Further, the criteria for judging the road condition in the main direction and the road conditions in other directions are different, and can be set as required. For example, the road condition may be divided into different levels, such as the three levels of "congestion", "slow moving", and "clear", and when the distance between the level of the road condition in the main direction and the level of the road condition in other directions is greater than a preset distance threshold, it is determined that the road condition in the main direction is different from the road condition in other directions.
For example, referring to fig. 3, if the main direction is the straight direction, the grades of the segment D38 and the segment D37 in the Lane35 driving to the right front are different from the grade of the Lane34 in the straight direction, and when the lengths of the segment D38 and the segment D37 are judged to be greater than the preset distance threshold, it may be determined that the road condition in the main direction is different from the road condition in other directions.
In specific implementation, the road condition information prompt can be realized through voice broadcast, the road condition state of the main direction can be specifically broadcast, one or more of the lanes entering the main direction can be prompted, and other contents can also be broadcast.
Further, if an illegal monitoring electronic eye is arranged on the current road, corresponding prompt contents, namely specific prompt contents, namely, the law can be diversified, can be additionally broadcasted.
In specific implementation, all or part of the broadcast contents of the original broadcast points of the current road in the main direction can be replaced, and the road condition information is prompted.
For example, with continued reference to fig. 3, when the vehicle runs on the road identified as Link31, the navigation route is driven to Link33, and if it is determined that there is an electronic eye monitor in front of the vehicle, and if it is determined that the preset prompting condition is met, the vehicle can be broadcasted at the voice broadcasting point of the Link 31: please drive along the rightmost lane, please note that there is a violation to take a picture in front, please change lanes in advance.
It will be appreciated by those of ordinary skill in the art that the various specific implementations described above can be implemented alone or in combination and are not limiting herein.
With reference to fig. 5, in an embodiment of the present invention, it may be sequentially determined whether each Link having a multi-directional road condition in a preset range has the multi-directional road condition by taking a Link where a vehicle is located as a starting point and taking a road unit (Segment) as a unit, and if yes, whether a preset prompt condition is met is determined, and when the condition is met, a broadcast is performed. Specifically, the method can comprise the following steps:
step S51, judging whether Segment is effective, if yes, executing step S52, otherwise, ending;
step S52, judging whether the Segment end point is deduced, if not, executing step S53, otherwise, ending;
step S53, determining Link in turn according to the driving direction of the navigation planning route;
step S54, judging whether the Link has multidirectional road conditions, if yes, executing step S55, otherwise executing step S57;
step S55, determining whether a preset condition is satisfied, if yes, performing step S56, otherwise performing step S57;
step S56, judging whether a corresponding broadcast point is found, if so, executing step S58, otherwise, ending;
step S57, judging whether the distance between the vehicle and the position of the vehicle reaches a preset range, if so, executing step S52, otherwise, ending;
and step S58, replacing the original broadcast content.
The Segment may be a division of the navigation planned route, specifically, a turning action may be used for the division, that is, the navigation planned route may be divided into multiple segments by the turning action, and a route that does not include the turning action may be used as the Segment. For each Link in Segment, the processing manner may be the same, for example, the processing manner of steps S54 to S56 in fig. 5, and this process may also be referred to as deduction.
In a specific implementation, the last Link of a Segment may be different from other links, for example, the content indicating that the user is going straight in the original broadcast content of the last Link may be deleted, so that the prompt that the user changes lanes in advance and enters the lane in the main direction brings better user experience.
It is understood that the broadcast content may be varied, and the above is only an example. Moreover, Segment obtained by dividing the turning action is used as a unit for prompting or not, so that subsequent broadcast content can be adjusted conveniently, and better user experience can be brought to subsequent broadcast.
In addition, the steps in the embodiment shown in fig. 5 may be implemented by combining the foregoing embodiments, and the road condition information prompt may also be implemented by adding or subtracting steps based on the embodiment shown in fig. 5.
In the embodiment of the invention, the multi-direction road condition of the current road is acquired in the navigation state, and the road condition information is prompted by combining the main direction and the multi-direction road condition. Because the multidirectional road conditions comprise the road conditions of different heading directions of the current road, and the main direction is the advancing direction of the navigation planning route on the current road, the road condition information can be prompted by combining the main direction and the multidirectional road conditions, the road conditions of the lanes needing to be driven by the vehicle can be prompted, and the road condition information is more accurate.
