The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a flowchart of a navigation method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step 101: and acquiring at least one navigation path according to the origin information and the destination information input by the user.
The main body of the navigation method of the embodiment may be an electronic Device, such as an in-vehicle Device, a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), a Wearable Device (Wearable Device), and so on. It should be noted that the specific type of the electronic device is not limited in this embodiment.
In this embodiment, a user may input the origin information and the destination information through a navigation request interface of a navigation application in the corresponding electronic device. The navigation path obtained in this step 101 may be requested by the electronic device from the navigation server through a navigation request, and may be all or part of the navigation path from the origin to the destination. The part of the navigation path may be selected as a path with shorter arrival time or less arrival distance, which is not limited in this embodiment.
Step 102: at least one key road characteristic and a driving difficulty value corresponding to each key road characteristic are obtained.
In this embodiment, the key road feature represents a road feature that may affect the driving difficulty during the driving process of the vehicle, and is generally related to at least one of the following: whether an isolation zone exists between a vehicle and a non-vehicle, the flow of people and vehicles, whether a U-turn intersection exists, the number of the U-turn intersections, whether a complex overpass exists, the number of the complex overpasses, whether a complex intersection exists, the number of the complex intersections, whether a roundabout exists, the number of the roundabout and the like.
For example, the key road features in the present embodiment include, but are not limited to: the method has the advantages that no isolation zone exists between the vehicle and the non-vehicle, the flow of people and vehicles exceeds a preset threshold value, the complex overpasses are arranged, the number of the complex overpasses exceeds a preset threshold value, the number of the turn-around intersections exceeds a preset threshold value, and the roundabout is arranged.
Optionally, the at least one acquired key road characteristic and the corresponding driving difficulty value thereof may be preset in the electronic device in advance and/or input by the user at present.
In one embodiment, the step 102 may include: firstly, receiving at least one key road characteristic input by a user; and then determining a driving difficulty value corresponding to each key road characteristic according to the corresponding relation between the preset key road characteristic and the driving difficulty value. The preset corresponding relation between the key road characteristics and the driving difficulty value can be set based on historical driving data. Therefore, the navigation path meeting the requirements of the user can be selected for the user and provided for the user by combining the requirements of the user on the navigation path and historical driving data, and the driving experience is improved.
In another embodiment, the step 102 may include: and receiving the at least one key road characteristic input by a user and a driving difficulty value corresponding to each key road characteristic. Therefore, the user can obtain the required navigation path based on the self condition, and the input driving difficulty value can be adjusted along with the increase of the driving experience, so that the driving experience is further improved while the required navigation path is obtained.
Step 103: and selecting the front N navigation paths with the minimum driving difficulty value from the at least one navigation path according to the at least one key road characteristic and the driving difficulty value corresponding to each key road characteristic.
Wherein N is an integer of 1 or more.
In this embodiment, the process of selecting the navigation path in this step may be: firstly, determining key road characteristics included in each navigation path according to at least one acquired key road characteristic; then, calculating the driving difficulty value of each navigation path according to the key road characteristics included in each navigation path and the driving difficulty value corresponding to the key road characteristics; and finally, selecting the front N navigation paths with the minimum driving difficulty value from the at least one navigation path according to the driving difficulty value of each navigation path. Therefore, the accuracy of the selected navigation path can be improved by calculating the driving difficulty value of each navigation path and selecting the navigation path with smaller driving difficulty value based on the driving difficulty value.
For example, assuming that three navigation paths are obtained according to the origin and the destination input by the user, the obtained key road features and corresponding driving difficulty values include: (1) the flow of people and vehicles exceeds a preset threshold value K, and the driving difficulty value is 5; (2) the flyover has a complex flyover, and the driving difficulty value is 3; (3) there is no isolation zone between the vehicle and the non-vehicle, and the driving difficulty value is 2.
If the key road characteristics included in the first navigation path are as follows: with a complex overpass, the second navigation path includes key road features: the flow of people and vehicles exceeds a preset threshold value K and no isolation strip exists between the vehicles and the non-vehicles, and the key road characteristics included in the third navigation path are as follows: the flow of people and vehicles exceeds a preset threshold value K, then: the driving difficulty value of the first navigation path is 3, namely the driving difficulty value corresponding to the key road characteristic 'with complex overpass'; the driving difficulty value of the second navigation path is 7, namely the sum of the driving difficulty values corresponding to the key road characteristics that the flow of people and vehicles exceeds a preset threshold value K and no isolation zone exists between the vehicles and the non-vehicles is included; the driving difficulty value of the third navigation path is 5, namely the driving difficulty value corresponding to the key road characteristic that the flow of people and vehicles exceeds the preset threshold value K is included. Thus, according to the driving difficulty values of the three navigation paths, the first 2 navigation paths with the minimum driving difficulty value, namely the first navigation path and the third navigation path, can be selected from the three navigation paths and provided for the user.
Step 104: and displaying the first N navigation paths.
In this embodiment, based on the first N navigation paths displayed, the user may select a target navigation path from the first N navigation paths, and navigate using the target navigation path.
According to the navigation method, at least one navigation path is obtained according to the origin information and the destination information input by the user, at least one key road characteristic and each driving difficulty value corresponding to the key road characteristic are obtained, the front N navigation paths with the minimum driving difficulty value are selected from the at least one navigation path according to the at least one key road characteristic and each driving difficulty value corresponding to the key road characteristic, the front N navigation paths are displayed, the navigation path with the lower driving difficulty can be provided for the user, and therefore the technical problem that the navigation path with the low driving difficulty cannot be provided for the user in the conventional navigation mode is solved.
Further optionally, in order to improve the driving experience of the user, in the embodiment of the application, the broadcasting can be performed according to the voice broadcasting mode selected by the user in the navigation process.
In an embodiment of the present application, the navigation method may further include: and receiving a voice broadcasting mode input by a user.
After the step 104, the navigation method may further include:
receiving a target navigation path selected by a user from the front N navigation paths, and navigating by using the target navigation path;
and broadcasting according to the voice broadcasting mode in the process of utilizing the target navigation path to navigate.
For example, to avoid poor riding experience due to low playing frequency, the playing frequency may be increased by the voice broadcast mode input by the user, such as that a prompt is broadcast at each intersection, and the user must insert a regular break.
For another example, in order to provide more time for the user to turn at the intersection, the voice broadcast mode input by the user can optimize the intersection turning broadcast strategy, such as advancing the prompt time point, prompting for multiple times, and the like.
For another example, in order to enable the user to accurately pass through a complex intersection, the voice broadcast mode input by the user may include splitting broadcast for the complex intersection, such as first prompting the speed reduction, then prompting the distance of the first intersection, the distance of the second intersection, and the like.
Like this, can report the mode according to the voice broadcast such as the broadcast frequency of user selection, report granularity, complicated crossing report many times, report at the navigation in-process to promote and drive and take experience.
