With continued reference to fig. 2, in step 230, when the cruising range is less than or equal to the route range corresponding to the initial navigation route, a target energy replenishment site is determined for the vehicle.
In this application, when the cruising range is less than or equal to the route range corresponding to the initial navigation route, it indicates that the energy reserve of the vehicle is insufficient to support the vehicle to travel the entire initial navigation route, in this case, a target energy supplement station may be determined for the vehicle.

In the present application, the energy consumption index is used to represent the energy consumption degree of the vehicle traveling on the initial navigation path, and specifically, the energy consumption index may refer to the energy consumption rate of the vehicle at each position on the initial navigation path, for example, for an electric car, the unit of the energy consumption index may be KW · h/Km, and for a fuel oil car, the unit of the energy consumption index may be L/100 Km.
In one embodiment of step 211 shown in fig. 3, the step of obtaining the energy consumption index of the vehicle on the initial navigation path may be performed according to the steps shown in fig. 4.

Referring to FIG. 5, a detailed flow diagram of determining a target energy replenishment site for the vehicle is shown, according to one embodiment of the present application. Specifically, the method comprises steps 231 to 232:
In the present application, since the first geographical area is a geographical area limited by the starting point position of the initial navigation path and the range as a radius, it can be understood that the vehicle can reach any one energy replenishment site in the first geographical area. Thus, the target energy replenishment site may be selected among the energy replenishment sites located within the first geographic area.
In one embodiment of step 232 shown in fig. 5, the selection of the target energy replenishment site among the energy replenishment sites located in the first geographic area may be performed according to the steps shown in fig. 6.
Referring to fig. 6, a detailed flow diagram of the selection of the target energy replenishment site among the energy replenishment sites located within the first geographic area is shown, according to one embodiment of the present application. Specifically, the method comprises steps 2321 to 2324:
In the application, a plurality of first geographical sub-areas may be determined in a first geographical area, and a first priority score may be determined for each first geographical sub-area, where the first priority score may be used to characterize a priority degree of the first geographical sub-area, and specifically, a higher first priority score of a certain first geographical sub-area indicates that the first geographical sub-area is more suitable as an energy supplement station selection area of a vehicle.
In this application, the first geographic sub-area with the highest first priority score may be used as a target first geographic sub-area, and the energy supplement sites in the target first geographic sub-area are displayed for the user to select.
In the present application, the energy supplement site selected by the user may be the target energy supplement site.

And 2, acquiring the distribution quantity of the energy supplement sites in each first geographical subregion.
And 3, calculating the first priority score based on the relative distance and/or the distribution quantity.
In this application, the first priority score may be calculated based on the relative distance, wherein the first priority score may be negatively correlated with the relative distance, i.e. the smaller the relative distance between the center of the area of the first geographical sub-area and the initial navigation path, the higher the calculated first priority score.
In the present application, the first priority score may be calculated based on the distribution number, wherein the first priority score may be positively correlated with the distribution number, that is, the higher the distribution number of the energy supplement sites in the first geographic sub-area is, the higher the calculated first priority score is.
In the present application, the first priority score may be calculated based on the relative distance and/or the distribution number, wherein the first priority score may be negatively correlated with the relative distance, and the first priority score may be positively correlated with the distribution number.
In order to make those skilled in the art better understand the scheme of selecting the target energy supplement site from the energy supplement sites located in the first geographic area in the present embodiment, a specific embodiment will be described below with reference to fig. 7.
Referring to fig. 7, a schematic diagram of the selection of the target energy replenishment site among the energy replenishment sites located within the first geographic area is shown, according to one embodiment of the present application.
As shown in fig. 7, when the vehicle drives from a starting point 701 to a destination 703, the generated initial navigation path is AC, the cruising destination of the vehicle is 702, that is, the cruising range is the length of the path AB, first, a first geographical area 704 may be determined with the starting point 701 as a center and the cruising range AB as a radius, and then a first geographical sub-area 1, a first geographical sub-area 2, a first geographical sub-area 3, a first geographical sub-area 4, a first geographical sub-area 5, and a first geographical sub-area 6 are determined in the first geographical area. In this embodiment, the first priority score of each first geographical sub-area may be determined according to the relative distance between the area center of the first geographical sub-area 1-6 and the initial navigation path, and the distribution number of the energy supplement stations in the first geographical sub-area 1-6.
It can be seen that the first priority score of the first geographical sub-area 4 is highest, and therefore, the energy replenishment sites in the first geographical sub-area 4 are displayed for selection by the user.
In the present application, on the one hand, by taking into account the distance of the first geographical sub-area from the initial navigation path, it is possible to provide the user with energy replenishment sites that can be reached quickly. On the other hand, by considering the distribution quantity of the energy sites in the first geographical subregion, more energy site selections can be provided for the user, and further user experience is improved.
In another embodiment, shown as step 232 in fig. 5, the selection of the target energy replenishment site among the energy replenishment sites located in the first geographic area may be performed according to the steps shown in fig. 8.
Referring to fig. 8, a detailed flow diagram of the selection of the target energy replenishment site among the energy replenishment sites located within the first geographic area is shown, according to one embodiment of the present application. Specifically, the method includes steps 2325 to 2326:
at 2325, energy supplement sites with relative distance to the initial navigation path lower than a first predetermined threshold are determined as candidate energy supplement sites in the first geographic area.
At 2326, the target energy replenishment site is selected from the candidate energy replenishment sites.
In the application, as the distance between the determined candidate energy supplement station and the initial navigation path is lower than a first preset threshold, the target energy supplement station selected from the candidate energy supplement stations can ensure that the vehicle can arrive quickly, so that the navigation efficiency is improved.
In this embodiment, in step 2326, the target energy supplementing site is selected from the candidate energy supplementing sites, and the following steps 1 to 3 may be performed:
And 2, calculating a second priority score of the candidate energy supplementing station based on the second congestion index, wherein the second priority score is negatively related to the second congestion index.
And 3, selecting the target energy supplement site from the candidate energy supplement sites based on the second priority score.
In the application, in the process of selecting the target energy supplement site from the candidate energy supplement sites, a second priority score is calculated by considering the congestion degree of each energy supplement site, and then the target energy supplement site is determined based on the second priority score, for example, the energy supplement site with the highest second priority score is determined as the target energy supplement site, so that a user can quickly reach the energy supplement site, and the vehicle navigation efficiency is improved.
In this embodiment, the second priority score of the candidate energy supply site is calculated, and the energy price of each energy supply site may also be referred to. The second priority score of the candidate energy charging site may be calculated based on the congestion index, and the second priority score of the candidate energy charging site may be calculated based on the congestion index and the idle rate, where the second priority score is directly related to the idle rate.
