Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The embodiment of the invention provides a navigation recommendation method, a navigation recommendation device, a navigation recommendation medium and computer equipment, which are used for solving the technical problem of low accuracy of the current navigation and recommendation service in the prior art. The method is applied to an APP (application program) or a vehicle machine which is loaded by a terminal side (such as a vehicle-mounted side or a mobile phone side) and used for managing a target vehicle, wherein the APP can execute various operations aiming at the target vehicle or respond to various requirements aiming at the target vehicle. For example, when the target vehicle requires charging, the device may provide a charging pile distribution map to the user in response to the charging request in order to screen for suitable charging stations. Alternatively, the user is provided with navigation services when they need navigation.

It should be noted that the target vehicle of the present embodiment does not represent a specific vehicle, and any vehicle may be used as the target vehicle of the present embodiment to implement the solution of the present embodiment, and any embodiment related to the present invention should be within the protection scope of the present invention.

The following describes a navigation recommendation method in detail with reference to an embodiment, and as shown in fig. 1, the method includes:

and 11, responding to a navigation request of a user, and acquiring a first destination corresponding to the navigation request.

In this embodiment, the navigation request is a request generated after the user inputs the first destination in the APP/car machine, and the navigation is performed according to the input first destination, and the first destination is a destination to which the user intends to go.

As an alternative embodiment, after obtaining the first destination corresponding to the navigation request, a navigation path from the current position of the target vehicle to the first destination is planned in response to the navigation request.

And step 12, analyzing according to the vehicle condition of the target vehicle driven by the user and the road condition of the navigation path corresponding to the navigation request, and obtaining an analysis result.

In the specific analysis process of this embodiment, the electric quantity threshold required for maintaining the safe driving of the target vehicle is obtained according to the vehicle condition of the target vehicle. Wherein the vehicle condition of the target vehicle includes: vehicle speed, driving time, power consumption rate, current remaining power, power threshold required to maintain safe driving of the target vehicle, and the like. The power consumption rate is determined by the power usage in the driving, for example, the higher the vehicle speed and the lower the air conditioner temperature, the faster the power consumption rate, and the remaining power can be calculated by referring to one or more factors such as the vehicle speed, the driving time, the power consumption rate, and the like. The electric quantity threshold value is obtained from the vehicle condition, and is determined by combining the general charging frequency of the user and the recommended electric quantity for battery maintenance, namely, the health of the vehicle battery is maintained, and the lowest electric quantity corresponding to the driving safety is ensured. And predicting the residual electric quantity of the target vehicle when the target vehicle reaches the first destination according to the vehicle condition and the road condition. The remaining power is determined by road conditions and vehicle conditions, such as road congestion conditions, and the remaining power is predicted by combining the driving speed, the driving time and the like of the target vehicle. And judging whether the residual electric quantity is higher than the electric quantity threshold value. If the electric quantity is lower than the electric quantity threshold value, the target vehicle cannot reach the first destination according to the analysis result.

As an alternative embodiment, although the target vehicle cannot directly reach the first destination, if there is a charging pile near the first destination, the charging pile near the first destination can be charged first, and then the target vehicle reaches the first destination after charging. Therefore, for the accuracy of recommendation, if it is determined in advance that the remaining power is lower than the power threshold, whether the charging pile is available within a first preset range centered on the first destination is searched. The first preset range can be determined according to the electric quantity of the user, for example, the first preset range is within the range of the driving range of the vehicle by taking the first destination as the center; and the available charging pile refers to a charging pile which can be normally used by the target vehicle, and if the available charging pile is not in the first preset range, the analysis result shows that the target vehicle cannot reach the first destination. If the available charging piles exist in the first preset range, whether the target vehicle can reach the available charging piles in the first preset range is further judged, namely whether the vehicle can reach is judged according to the electric quantity condition; and if the target vehicle can reach the available charging pile within the first preset range, recommending the available charging pile within the first preset range to the user. And if the charging pile is not available within the first preset range, determining that the target vehicle cannot reach the first destination, and executing subsequent recommendation steps.

And step 13, if the analysis result shows that the target vehicle cannot reach the first destination, determining whether a second destination which has the same type as the first destination and can be reached by the target vehicle exists according to the navigation path.

Wherein the second destination is a destination that the target vehicle can reach and is of the same type as the first destination. For example, the first destination and the second destination may be both department stores, hospitals, etc.

With the above scheme, in the case where the target vehicle is navigated to the first destination, if it is analyzed that the target vehicle cannot reach the first destination, one or more embodiments of the present invention can recommend a second destination that is the same type as the first destination and that the target vehicle can reach. The method not only considers the subjective requirements of the user, but also considers the actual objective conditions of the target vehicle, so that the user can be provided with the destination meeting the requirements for selection based on the objective actual conditions on the basis of fully knowing the requirements of the user, the recommendation accuracy is improved, and the driving safety is also ensured.

In an optional recommended embodiment, a preset distance range of a navigation path is obtained; determining whether the second destination exists within the preset distance range. For example, a second destination within 50 meters of a navigation path may be a potential candidate point, and the embodiment does not limit that the second destination must be on the navigation path.

If a plurality of (for example, more than two) candidate destinations with the same type as the first destination are searched on the navigation path. Randomly selecting one destination to be selected from a plurality of destinations to be selected as a second destination; or selecting the destination to be selected closest to the target vehicle from a plurality of destinations to be selected as the second destination. There are, of course, many other alternatives, which will not be described in detail herein.

In an optional recommended embodiment, if the second destination does not exist, in order to enable the target vehicle to smoothly reach the first destination and ensure driving safety, a third preset range is determined by taking the current position of the target vehicle as a center; searching for available charging piles within a third preset range for recommendation. The third preset range can be any range value according to actual conditions; the available charging pile refers to a charging pile which can be reached and used by the target vehicle, for example, the target vehicle can drive for 10 kilometers according to vehicle conditions, and the available charging pile within a range of 5 kilometers away from the target vehicle is recommended to charge the target vehicle so as to ensure driving safety.

And 24, if the second destination exists, recommending the second destination to the user.

For example, the navigation route corresponding to the first destination is displayed together with the presentation information. However, since the target vehicle cannot reach the first destination, the guidance route of the first destination may not be displayed on the display interface, and the guidance information may be generated based on the second destination and displayed in place of the guidance route of the first destination. And in the process of recommending the second destination, generating prompt information according to the second destination and displaying the prompt information on a display interface, wherein the prompt information is specifically used for prompting a user to navigate according to the second destination.

In an optional recommended embodiment, in order to sufficiently ensure driving safety, in the recommending process, whether an available charging pile exists in a second preset range with a second destination as a center is judged; the second preset range is determined according to the actual road condition; and the available charging pile refers to a charging pile which can be reached and used by the target vehicle, for example, the available charging pile is positioned on a navigation path of the target vehicle to a second destination. And if the available charging piles exist in the second preset range, recommending the available charging piles and the second destination in the second preset range to the user. The recommendation process is similar to that described above and will not be described herein.

In a specific implementation process, if more than two destinations to be selected with the same type as the first destination are searched from the navigation path, for each destination to be selected, the number of available charging piles corresponding to each destination to be selected can be determined, for example, the number of available charging piles within a second preset range of each destination to be selected is determined; and determining a second destination according to the distance between each destination to be selected and the target vehicle and/or the number of available charging piles corresponding to each destination to be selected. For example, the destination to be selected which is closest to the vehicle and/or has the largest number of available piles is the second destination, so that the destination which meets the requirements of the target vehicle better can be obtained, and the driving safety is guaranteed.

As an optional embodiment, after recommending the second destination to the user, in response to a navigation request of the user for the second destination, determining a navigation path corresponding to the second destination for navigation.

For example, when the user to whom the target vehicle belongs inputs department store 1 in the map input box in the APP, but analyzes that the target vehicle cannot reach the department store 1, determines whether a place with similar properties to the destination exists along the way, such as department store 2, and if so, displays the prompt information corresponding to the department store 2 in the map of the APP without displaying the navigation path of the department store 1. The prompt message is as follows: the current electric quantity can not reach department store 1, whether go to department store 2. If the user confirms to go, the department store 2 is used as the destination for navigation. For another example, if the available charging pile near the department store 2 is searched, the available charging pile near the department store 2 and the prompt information of the department store 2 are displayed in the APP map.
