specific Embodiment approach

[0112] This embodiment discloses a specific implementation manner of determining the fan-shaped area to which each edge coordinate point belongs, as follows:

[0113] 1. Calculate the angle between the straight line from the search start point to the edge coordinate point and the reference line from the search start point;

[0114] Specifically, the reference line emitted from the starting point of the search may be in any set direction. For example, in a Cartesian coordinate system, the reference line may be the X-axis direction or the Y-axis direction. In the polar coordinate system, the reference line can be the direction of the polar axis, etc.

[0115] 2. According to the predetermined angle intervals of each fan-shaped area relative to the reference line, in the angle intervals of each fan-shaped area, determine the angle interval including the included angle;

[0116] 3. Taking the fan-shaped area corresponding to the determined angle interval including the included a...

Embodiment approach

[0174] An optional implementation is as follows:

[0175] For the intersecting continuable areas, delete the edge coordinate points where one of the continuable areas falls within the intersecting area of ​​the other endurable area, and the edge coordinates that do not fall within the area of ​​the other endurable area point.

[0176] Optionally, for the two intersecting endurance areas, one may be selected and retained, and all edge coordinate points of the other endurance area are deleted. According to this processing method, there will be no intersection area after processing, so there will be no problem of repeated drawing. Among them, preferably, as mentioned above, among the two intersecting endurable areas, the one with the larger bounding rectangle area may be selected to be retained, and all edge coordinate points of the other endurable area with a smaller bounding rectangle area are deleted.

[0177] combine figure 1 Be explained:

[0178] This application can ra...

Abstract

The invention discloses an endurance area determination method and device for vehicles. In response to an endurance area determination request, vacuation is performed on edge coordinate points of at least two determined endurance areas, whether the endurance areas are intersected is judged, as for the intersected endurance areas, edge coordinate points, falling into the other one of the two intersected endurance areas, of at least one of the endurance areas are deleted, and a to-be-output endurance area is formed by remaining edge coordinate points of each endurance area determined in responseto the endurance area determination request. In the intersected endurance areas, the edge coordinate points, falling into the other one of the two intersected endurance areas, of at least one of theendurance areas are deleted, the problem of abnormal display caused by the fact that the edge coordinate points and other edge coordinate points in the intersected endurance areas define an intersection area and the intersection area is repeatedly drawn on a map interface is solved.

Description

technical field [0001] The present application relates to the technical field of navigation, and more specifically, to a method and device for determining a cruising range. Background technique [0002] With the improvement of people's living standards, the requirements for travel convenience are also getting higher and higher. Automobiles have been widely popularized as a comfortable and fast means of transportation. Today's cars generally provide navigation functions, which can provide users with path planning, which greatly facilitates people's daily travel. [0003] During the driving process, sometimes the user needs to know the cruising range of the vehicle under the current position and the remaining energy of the vehicle. The navigation server searches for each position point that can be reached by the remaining energy from the current position of the vehicle, and these position points form the endurance area. [0004] The inventors of this case found through rese...
