[0008] In combination with the first aspect and the above implementation, in one possible implementation, the method further includes: if there is a second turning point after the first turning point, determining whether the projection length is less than a second preset length, wherein the second preset length is greater than the first preset length; if the projection length is not less than the second preset length, determining the second display position of the vehicle logo on the screen when the target vehicle reaches the first turning point according to the second direction.

[0010] In combination with the first aspect and the above implementation, in one possible implementation, when the vehicle is traveling between the first turning point and the second turning point, the first display position of the target vehicle's logo on the screen remains unchanged.

[0011] In combination with the first aspect and the above implementation method, in one possible implementation method, the above-mentioned preset angle range is determined based on at least two straight lines passing through the center of the screen.

[0012] Secondly, a navigation map display device is provided, the device comprising: a first determining module, configured to: determine a first turning point where the driving direction of the target vehicle changes according to the planned route of the target vehicle; a judging module, configured to: judge whether a second direction exceeds a preset angle range corresponding to a first direction, wherein the first direction is the driving direction of the target vehicle before reaching the first turning point, and the second direction is the driving direction of the target vehicle after reaching the first turning point; a second determining module, configured to: determine a first display position of the vehicle logo on the screen displaying the navigation map when the target vehicle reaches the first turning point, based on the first direction, if the second direction does not exceed the preset angle range corresponding to the first direction, wherein the distance between the first display position and a first side of the screen is determined according to a first preset value, wherein the first side is the side that extends in the opposite direction of the first direction and intersects the screen; and a display module, configured to: display the navigation map based on the first display position of the vehicle logo.

Here, the first direction is the driving direction of the target vehicle before reaching the first turning point, and the second direction is the driving direction of the target vehicle after reaching the first turning point.

[0016] If the second direction does not exceed the preset angle range corresponding to the first direction, the first display position of the vehicle logo on the screen when the target vehicle reaches the first turning point is determined based on the first direction. The distance between the first display position and the first edge of the screen is less than a first preset value, and the first edge is the edge that extends in the opposite direction of the first direction and intersects the screen. Finally, based on the first display position of the vehicle logo, a navigation map is displayed.

[0017] This application can adjust the display position of the navigation map in real time according to the planned route, thereby displaying a more complete navigation map on the in-vehicle navigation screen and improving screen utilization. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0040] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0042] refer to Figure 1The illustration shows the vehicle's logo centered on the screen. Figure 1 As shown, in current in-vehicle navigation systems, when viewed from the "north-facing" angle, the vehicle logo 10 used to indicate the vehicle's location is usually displayed in the center of the screen (i.e., centered relative to the long side of the screen and centered relative to the wide side of the screen).

[0043] However, this allows the screen to display the vehicle's subsequent driving route (such as...). Figure 1 The area of ​​the shaded route is reduced to half, resulting in low screen utilization and less navigation map display.

[0044] To address the aforementioned issues, this application proposes a method, apparatus, storage medium, and terminal for displaying navigation maps, which can improve the utilization rate of in-vehicle navigation screens and enable the screen to display more complete navigation maps.

[0045] The following will describe in more detail the steps of the navigation map display method in this exemplary embodiment, with reference to the accompanying drawings and embodiments.

[0046] Figure 2 This is a schematic flowchart of a navigation map display method provided in an embodiment of this application. Figure 2 The method shown can be applied to in-vehicle navigation systems.

[0047] S210, based on the planned route of the target vehicle, determine the first turning point where the target vehicle's driving direction changes.

[0048] In an exemplary embodiment, after the user starts the target vehicle, they enter the destination into the vehicle's navigation system. Once the navigation system obtains the destination, it determines at least one planned route (or navigation route) based on the target vehicle's location and the destination, and displays the planned route to the user on the screen. After selecting one of the planned routes, the user sets the navigation view to a "north-facing" view.

[0049] Afterwards, users can set the area on the screen used to display the navigation map according to their own needs. In other words, users can customize the display position of the target vehicle's logo on the screen. The display position of the logo on the screen can be a preset display scheme in the navigation system, and / or, it can be set by the user by entering a first preset value.

[0050] For example, refer to Figures 3a-3b The diagram shows the display position of the car logo on the screen. Assume the width of the screen is x and the length of the length of the long side is y.

[0051] Figure 3a The display scheme for the "Comfort" mode provided by the navigation system. For example... Figure 3aAs shown, in this mode, the first preset value is set to... That is: the distance between the car logo 10 and the long side of the screen is (And centered relative to the long side), the distance between the car logo 10 and the wide edge of the screen is... (And centered relative to the wide side). In other words, on the screen... The area is used to display navigation maps and plan routes;

[0052] Figure 3b The display scheme provided for the "extreme" conditions of the navigation system. For example... Figure 3b As shown, in this mode, the first preset value is set to... That is: the distance between the car logo 10 and the long side of the screen is (And centered relative to the long side), the distance between the car logo 10 and the wide edge of the screen is... (And centered relative to the wide side). In other words, on the screen... The area is used to display navigation maps and plan routes.

[0053] For example, in addition to the preset display scheme provided by the navigation system, the user can also set a first preset value for the distance between the car logo 10 and the screen boundary. For example, the user sets the first preset value to... The distance between the car logo 10 and the long side of the screen is The distance from the wide edge of the screen is

[0054] It should be noted that the specific value of the first preset value mentioned above is only an example and is not limited in this embodiment.

[0055] In an exemplary embodiment, reference is made to Figure 4 The diagram shows the preset angle range.

[0056] For example, the preset angle range can be determined based on at least two straight lines passing through the center of the screen. Figure 4 As shown, taking a screen with a shape close to a rectangle as an example, the two diagonals of the screen can be used as regional dividing lines to divide the entire display area presented by the screen into 4 display sub-areas: ①, ②, ③, and ④. Each of the 4 display sub-areas corresponds to a preset angle range.

[0057] It should be noted that the above-mentioned division of display sub-regions / preset angle ranges is only an example. The display area can also be divided more finely according to the shape of the screen, but this embodiment does not limit it.

[0058] In an exemplary embodiment, reference is made to Figure 5 The diagram shown illustrates an example of determining the initial display position of a car logo.

[0059] like Figure 5 As shown, the planned route starts at point A (i.e., the location of the target vehicle in the actual environment), changes direction at point B and travels towards point C, with point C as the destination.

[0060] First, the initial display position of the car logo 10 needs to be determined. For example, point A can be used as the center point to determine which display sub-area the first direction corresponding to the planned route AB faces, and then determine the preset angle range corresponding to the first direction of the planned route AB. For example, refer to... Figure 5 For ease of explanation, a gray dashed line parallel to the area division line is drawn in the diagram with point A (the starting point of the planned route AB) as the center. Clearly, the sub-area to which the planned route AB faces is ①. Therefore, the preset angle range corresponding to the first direction of the planned route AB can be determined as ①.

[0061] Then, based on the preset angle range ① corresponding to the first direction mentioned above, the initial display position of the car logo 10 is determined.

[0062] For example, suppose the first preset value mentioned above is The initial display position of the car logo 10 is determined to be within a preset angle range ③ that is symmetrical to the center of the preset angle range ①, and the distance between this initial display position and the long side of the screen (that is, the side that extends in the opposite direction of the first direction and intersects the screen) is... like Figure 5 As shown, the planned routes A'B' and B'C' are the actual planned routes displayed on the screen.

[0063] refer to Figure 6 The diagram shown illustrates another example of determining the initial display position of the car logo.

[0064] For example, suppose the planned route starts at point A and ends at point B. Figure 6 As shown, the first direction mentioned above points towards a preset angle range ②. Assuming the first preset value is still... The initial display position of the car logo 10 is determined to be within a preset angle range ④ that is symmetrical to the center of preset angle range ②, and the distance between this initial display position and the wide edge of the screen (that is, the edge that extends in the opposite direction of the first direction and intersects the screen) is... The planned route A'B' is the actual planned route displayed on the screen.

[0065] In an exemplary embodiment, the target vehicle then begins to travel along the planned route. It is understood that while the target vehicle is moving, the position of the vehicle marker 10 remains unchanged, while the navigation map moves in the opposite direction to the target vehicle's direction of movement.

[0066] In an exemplary embodiment, in Figure 6In the scenario shown, the planned route is a straight line with no change in direction, therefore the navigation system does not need to perform the aforementioned judgment process; while Figure 5 In the case shown, the planned route changes direction at point B'. When the target vehicle reaches the first turning point B', the navigation system needs to re-determine the position of vehicle marker 10.

[0067] S220, determine whether the second direction exceeds the preset angle range corresponding to the first direction, wherein the first direction is the driving direction of the target vehicle before reaching the first turning point, and the second direction is the driving direction of the target vehicle after reaching the first turning point.

[0068] refer to Figure 7 The diagram shown illustrates how to determine the first display position of the car logo.

[0069] For example, such as Figure 7 As shown, next, it is determined whether the second direction corresponding to the planned route B'C' exceeds the preset angle range corresponding to the first direction corresponding to the planned route A'B. In other words, it is determined whether the second direction corresponding to the planned route B'C is still facing the preset angle range①.

[0070] If the second direction corresponding to the planned route B'C' exceeds the preset angle range corresponding to the first direction (that is, the display sub-area facing the second direction is the same as that of the first direction), then point B' can be determined as the first turning point on the planned route.

[0071] like Figure 7 As shown, it can be seen that the second direction corresponding to the planned route B'C' is still within the preset angle range ①.

[0072] S230, if the second direction does not exceed the preset angle range corresponding to the first direction, determine the first display position of the car logo on the screen displaying the navigation map when the target vehicle reaches the first turning point according to the first direction, wherein the distance between the first display position and the first side of the screen is equal to the first preset value, wherein the first side is the side that extends in the opposite direction of the first direction and intersects with the screen.

[0073] S240 displays a navigation map based on the first display position of the car logo.

[0074] In an exemplary embodiment, reference is made to Figure 8 The illustration shows an example of a navigation map displayed based on the first display position of a car logo. Figure 8As shown, if the planned route is still within the preset angle range ① in the second direction corresponding to B'C, then the display position of the car logo 10 can be determined to be the same as the display position when traveling in the first direction (this display position of the car logo 10 is denoted as the first display position). Similarly, the distance from the long side of the screen (that is, the side that extends in the opposite direction of the first direction and intersects with the screen) is... The location.

[0075] In an exemplary embodiment, the navigation system can then continue to display the remaining navigation map and planned route based on the aforementioned first display position of the vehicle logo 10. That is, Figure 8 The planned route B'C' shown is the actual planned route displayed on the screen.

[0076] In another possible implementation, Figure 9 This is a schematic flowchart illustrating the determination of the first display position of a car logo according to an embodiment of this application.

[0077] S910 determines the target edge of the screen based on the second direction if the second direction exceeds the preset angle range.

[0078] S920, determine the projection length of the planned route in the second direction onto the target side.

[0079] In an exemplary embodiment, reference is made to Figure 10 The diagram shown illustrates another example of determining the first display position of the car logo.

[0080] like Figure 10 As shown, assume that the planned route A'B remains unchanged, while the planned route B'C changes. Similarly, first determine whether the second direction corresponding to the planned route B'C exceeds the preset angle range of the first direction corresponding to the planned route A'B; that is, determine whether the second direction corresponding to the planned route B'C exceeds the preset angle range ①. It can be seen that the second direction corresponding to the planned route B'C is within the preset angle range ③.

[0081] Since the second direction exceeds the preset angle range of the first direction, it is necessary to determine the target edge of the screen based on the second direction, thereby determining the projection length of the planned route in the second direction on the target edge.

[0082] The method for determining the target edge of the screen can be as follows: when the second direction is oriented towards a preset angle range ① and a preset angle range ③, the wide edge of the screen is taken as the target edge; when the second direction is oriented towards a preset angle range ② and a preset angle range ④, the long edge of the screen is taken as the target edge.

[0083] Continue to refer to Figure 10Since the planned route B'C' faces the preset angle range ③, the target edge can be determined as the width of the screen.

[0084] S930, determine whether the projection length is less than the first preset length.

[0085] For example, continue to refer to Figure 10 The projection length of the planned route B'C' onto the wide side of the screen is the length of line segment m.

[0086] Next, it is determined whether the projected length is less than a first preset length. The first preset length can be set according to the aforementioned first preset value. For example, when the aforementioned first preset value is... At that time, the target edge can be set. The first preset length is, that is, when the target side is the longer side of the screen, the first preset length is... When the target side is the width of the screen, the first preset length is

[0087] It should be noted that the above-mentioned first preset length value is only an example and is not necessarily required to be determined. For example, when the above-mentioned first preset value is... At that time, the target edge can be set. Set the first preset length, or set the target edge. The first preset length is set as follows, and so on. The value of the first preset length can be adjusted according to actual needs. This embodiment does not impose any limitations.

[0088] Continue to refer to Figure 10 It can be seen that the projected length (length of line segment m) of the planned route B'C' is less than the length of the target side. That is, the projected length is less than the first preset length.

[0089] S940, when the projection length is less than the first preset length, determines the first display position of the car logo on the screen when the target vehicle reaches the first turning point.

[0090] refer to Figure 11 The diagram shows another example of a navigation map displayed based on the first display position of the car logo.

[0091] For example, if the projection length is less than the first preset length, the display position of the car logo 10 can remain the same as when traveling in the first direction. Figure 11 As shown, the display position of the car logo 10 remains unchanged, also at a distance from the long side of the screen (that is, the side that extends in the opposite direction from the first direction and intersects the screen). The location.

[0092] S950, provided that the projected length is not less than the first preset length, determines whether there is a second turning point after the first turning point where the driving direction of the target vehicle changes.

[0093] In an exemplary embodiment, reference is made to Figure 12 The diagram shown illustrates an example of determining the second display position of the car logo.

[0094] like Figure 12 As shown, assume that the planned route A'B' remains unchanged, while the planned route B'C' changes.

[0095] Similarly, first determine whether the second direction corresponding to the planned route B'C' exceeds the preset angle range corresponding to the first direction corresponding to the planned route A'B. It can be seen that the second direction corresponding to the planned route B'C is oriented towards the preset angle range ②.

[0096] Continue to refer to Figure 12 Since the planned route B'C' faces the preset angle range ②, the target side can be determined to be the long side of the screen. Furthermore, the projection length of the planned route B'C' onto the long side of the screen is the length of line segment m.

[0097] It can be seen that the projected length (length of line segment m) of the planned route B'C' is greater than that of the target side. That is, the projected length is greater than the first preset length.

[0098] Therefore, if the projected length of the planned route B'C' is not less than the first preset length, the next step is to determine whether there is a second turning point after the first turning point B' where the target vehicle's driving direction changes.

[0099] S960, in the absence of a second turning point, the second display position of the vehicle logo on the screen when the target vehicle reaches the first turning point is determined according to the second direction, wherein the distance between the second display position and the second side of the screen is determined according to a second preset value, wherein the second side is the side that extends in the opposite direction of the second direction and intersects the screen.

[0100] Continue to refer to Figure 12 As can be seen, there is no second turning point after the first turning point B', meaning that the planned route does not change direction after point C'. Therefore, the judgment process can be terminated, and the second display position of the car logo on the screen when the target vehicle reaches the first turning point can be determined based on the second direction.

[0101] Continue to refer to Figure 12 It can be seen that the second direction corresponding to the planned route B'C is within the preset angle range ④.

[0102] refer to Figure 13 The illustration shows a diagram of a navigation map displayed in a second display position based on a car logo.

[0103] like Figure 13 As shown, assuming the first preset value is still 1 / 4, the second display position of the car logo 10 is determined to be within the preset angle range ②, which is symmetrical to the center of the preset angle range ④, and the distance between this second display position and the wide side of the screen (that is, the side that extends in the second direction in the opposite direction and intersects with the screen) is... The planned route B'C' is the actual planned route displayed on the screen.

[0104] S970, if there is a second inflection point after the first inflection point, determine whether the projected length is less than the second preset length, wherein the second preset length is greater than the first preset length.

[0105] In an exemplary embodiment, reference is made to Figure 14 The diagram shown is another example of determining the first display position of the car logo.

[0106] like Figure 14 As shown, assume that planned routes A'B' and B'C' remain unchanged, but planned route C'D' is added after planned route B'C'.

[0107] It can be seen that the preset angle range corresponding to the planned route C'D' is ①, which is different from the preset angle range of the planned route B'C. Therefore, point C' can be determined as the second turning point on the planned route.

[0108] If a second turning point exists after the first turning point, then it is determined whether the projected length of the planned route B'C' is less than the second preset length.

[0109] The second preset length should be greater than the first preset length.

[0110] For example, when the target side is the wide side of the screen, and the aforementioned first preset length is... At that time, the second preset length can be When the target side is the width of the screen, and the aforementioned first preset length is... At that time, the second preset length can be

[0111] It should be noted that the value of the second preset length mentioned above is only an example. The value of the second preset length can be adjusted according to actual needs. This embodiment does not impose any limitations.

[0112] Continue to refer to Figure 14 It can be seen that the projected length (length of line segment m) of the planned route B'C' is greater than that of the target side. And smaller than the target edge That is, the projected length is less than the second preset length.

[0113] S980, when the projection length is less than the second preset length, determines the first display position of the car logo on the screen when the target vehicle reaches the first turning point according to the first direction.

[0114] In an exemplary embodiment, reference is made to Figure 15 The diagram shown is another example of a navigation map displayed based on the first display position of the car logo.

[0115] If the projection length is less than the second preset length, the display position of the car logo 10 can remain the same as when traveling in the first direction. For example... Figure 15 As shown, the display position of the car logo 10 remains unchanged, also at a distance from the long side of the screen (that is, the side that extends in the opposite direction from the first direction and intersects the screen). The location.

[0116] S990, provided that the projection length is not less than the second preset length, determines the second display position of the vehicle logo on the screen when the target vehicle reaches the first turning point according to the second direction.

[0117] In an exemplary embodiment, reference is made to Figure 16 The diagram shown illustrates another example of determining the second display position of the car logo.
