[0002] A navigation device is known which displays a turn arrow on a display when it detects that a vehicle is within a certain distance from a turning intersection, prompting the driver that a turn will be made ahead.

[0043] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0044] Figure 1 is a flow chart of a navigation method according to a first embodiment of the present invention. Figure 1 As shown, the navigation method may include:

[0045] Step S101, obtaining the distance between the current position of the vehicle and the turning intersection, and determining whether the distance is less than a predetermined distance threshold.

[0046] First, the current position of the vehicle is acquired in real time, and the distance between the current position of the vehicle and the turning intersection is calculated in real time based on the current position of the vehicle, so as to determine whether the distance between the current position of the vehicle and the turning intersection is less than a predetermined distance threshold. It should be noted that the distance threshold can be preset, and the embodiment of the present invention does not limit this.

[0047] Step S102, in response to the distance being less than the distance threshold, displaying a turn sign indicating a turn on the vehicle-mounted display, and the turn sign has a first display mode and a second display mode, and the first display mode and the second display mode are switched based on the driving speed of the vehicle; wherein, in the first display mode, the size of the turn sign changes dynamically, and in the second display mode, the size of the turn sign remains unchanged.

[0048] If the distance between the current position of the vehicle and the turning intersection is less than the distance threshold, a turning sign indicating the turn is displayed on the vehicle display, and the turning sign has a first display mode and a second display mode. In the first display mode, the size of the turning sign changes dynamically, and in the second display mode, the size of the turning sign remains unchanged. In addition, after the turning sign is displayed on the vehicle display, the first display mode and the second display mode are switched based on the vehicle's driving speed.

[0049] In one embodiment, the vehicle-mounted display is a head-up display.

[0050] Since the first display mode and the second display mode are switched based on the vehicle's driving speed, and the size of the turn sign changes dynamically in the first display mode and remains unchanged in the second display mode, the size of the turn sign will not change suddenly, allowing the driver to effectively perceive the distance between the vehicle's current position and the turning intersection and the vehicle's driving speed, thereby providing a good driving assistance experience.

[0051] Figure 2 is a flow chart of a navigation method according to a second embodiment of the present invention. As another embodiment of the present invention, Figure 2 As shown, the navigation method may include:

[0052] Step S201, obtaining the distance between the current position of the vehicle and the turning intersection.

[0053] Step S202, determine whether the distance is less than a predetermined distance threshold; if so, execute step S203; if not, end.

[0054] Step S203: displaying a turning sign indicating a turn on the vehicle-mounted display.

[0055] Step S204, detecting the driving speed of the vehicle.

[0056] Step S205, determining whether the driving speed is greater than or equal to a predetermined speed threshold; if so, executing step S206; if not, executing step S207.

[0057] After the turning mark indicating the turning is displayed on the vehicle display, the driving speed of the vehicle is detected, and it is determined whether the driving speed of the vehicle is greater than or equal to a predetermined speed threshold. It should be noted that the speed threshold can be preset, and the embodiment of the present invention does not limit this.

[0058] Step S206, controlling the turning sign to be in a first display mode, in which the size of the turning sign changes dynamically.

[0059] If the vehicle's running speed is greater than or equal to a predetermined speed threshold, the turning sign is controlled to be in a first display mode. In the first display mode, the size of the turning sign changes dynamically to prevent a sudden change in the size of the turning sign.

[0060] Optionally, in the first display mode, the size of the turn mark increases as the distance decreases. That is, the larger the distance between the current position of the vehicle and the turning intersection, the smaller the size of the turn mark; the smaller the distance between the current position of the vehicle and the turning intersection, the larger the size of the turn mark. Figure 3a Therefore, the size of the turn sign will not change suddenly, so that the driver can effectively perceive the distance between the current position of the vehicle and the turning intersection, thus providing a good driving assistance experience.

[0061] Optionally, in the first display mode, the turn sign moves cyclically toward the direction of the turning intersection and keeps flashing, and the number of the turn sign is one. Figure 3b As shown, in the first display mode, the turn sign moves circularly toward the direction of the turning intersection, that is, the display position of the turn sign on the vehicle-mounted display also changes dynamically, and moves circularly toward the direction of the turning intersection, and each movement is accompanied by a flash, which helps to remind the driver of the turning direction, allowing the driver to effectively perceive the turning direction, thereby providing a good driving assistance experience.

[0062] Optionally, the time when the turn sign disappears at the previous position and the time when it appears at the next position can be controlled so that the turn sign at the previous position and the turn sign at the next position are displayed on the vehicle display at the same time at least at a certain moment. In the first display mode, the time when the turn sign disappears at the first display position on the vehicle display and the time when the turn sign appears at the second display position on the vehicle display can be the same or different. If the disappearance time is earlier than the appearance time, only one turn sign will be seen on the vehicle display. Figure 3b If the disappearance time is later than the appearance time, two turn signs will be seen on the vehicle display at the same time, such as Figure 3cAs shown, the turn sign at the first display position has not completely disappeared, and the turn sign at the second display position has been displayed. Optionally, the turn sign at the previous position can be controlled to gradually fade during the disappearance process to form a gradient effect. In this way, by allowing the driver to visually observe the contrast between the turn signs at the previous position and the next position, it helps to better remind the driver of the turning direction, allowing the driver to more effectively perceive the turning direction, thereby providing a better driving assistance experience.

[0063] Similarly, by controlling the time when the turn sign disappears at the previous position and the time when it appears at the next position, the turn signs at three or more positions can be simultaneously displayed on the vehicle display at least at a certain moment.

[0064] Optionally, the angle of the moving path of the turning mark is the same as the turning angle of the turning intersection. Figure 3d As shown, the angle of the moving path of the turn sign is the same as the turning angle of the turning intersection, and the vertex of the turn sign also points to the turning angle of the turning intersection. This helps to better remind the driver of the turning direction, allowing the driver to perceive the turning direction more effectively, thereby providing a better driving assistance experience.

[0065] Step S207, controlling the turn sign to be in a second display mode, in which the size of the turn sign remains unchanged.

[0066] In the second display mode, the size of the turn sign remains unchanged, so that the driver can perceive that the vehicle is currently traveling at a slower speed, thereby providing a good driving assistance experience.

[0067] Optionally, in the second display mode, the size of the turn sign remains unchanged at the size when the turn sign is switched to the second display mode. If the vehicle's driving speed drops from being greater than or equal to the speed threshold to being less than the speed threshold, the turn sign switches from the first display mode to the second display mode, and at this time, the size of the turn sign is the size when the turn sign is switched to the second display mode.

[0068] It should be noted that if after the turn sign is displayed on the vehicle display, it is detected that the vehicle's driving speed is less than the speed threshold, the turn sign directly enters the second display mode. At this time, the size of the turn sign is the size when the turn sign directly enters the second display mode.

[0069] Optionally, in the second display mode, the number of the turn signs is one or more, the sizes of the turn signs are the same, the display positions of the turn signs remain unchanged and they keep flashing synchronously. Figure 4aAs shown, in the second display mode, multiple turning signs can be displayed on the vehicle display, and the display position of each turning sign remains unchanged, that is, the turning sign does not move. In order to better remind the driver, each turning sign can also flash synchronously.

[0070] like Figure 4b As shown, the angles of the display paths of the multiple turn signs are the same as the turning angle of the turning intersection, and the apex of the turn sign also points to the turning angle of the turning intersection. This helps to better remind the driver of the turning direction, allowing the driver to perceive the turning direction more effectively, thereby providing a better driving assistance experience.

[0071] It should be noted that after the turn sign is displayed on the vehicle display, the vehicle's driving speed is detected in real time, and the turn sign is controlled to be in the first display mode or the second display mode based on the vehicle's driving speed, so steps S204-S207 need to be repeated.

[0072] Figure 5 is a schematic diagram of a navigation device according to an embodiment of the present invention. Figure 5 As shown, the navigation device includes a distance unit 501 and a display unit 502; wherein the distance unit 501 is used to obtain the distance between the current position of the vehicle and the turning intersection, and determine whether the distance is less than a predetermined distance threshold; the display unit 502 is used to display a turning mark for indicating a turn on the vehicle display in response to the distance being less than the distance threshold, and the turning mark has a first display mode and a second display mode, and the first display mode and the second display mode are switched based on the driving speed of the vehicle;

[0073] Wherein, in the first display mode, the size of the turn mark changes dynamically, and in the second display mode, the size of the turn mark remains unchanged.

[0074] Optionally, the display unit 502 is further used for:

[0075] detecting a driving speed of the vehicle, and determining whether the driving speed is greater than or equal to a predetermined speed threshold;

[0076] In response to the driving speed being greater than or equal to the speed threshold, the turn sign is controlled to be in a first display mode.

[0077] In response to the driving speed being less than the speed threshold, the turn sign is controlled to be in a second display mode.

[0078] Optionally, in the first display mode, the size of the turn sign increases as the distance decreases; in the second display mode, the size of the turn sign remains unchanged at the size when the turn sign is switched to the second display mode.

[0079] Optionally, in the first display mode, the turn sign cyclically moves toward the direction of the turning intersection and keeps flashing, and the number of the turn sign is one.

[0080] Optionally, the angle of the moving path of the turning mark is the same as the turning angle of the turning intersection.

[0081] Optionally, in the second display mode, the number of the turn signs is one or more, the sizes of the turn signs are the same, the display positions of the turn signs remain unchanged and keep flashing synchronously.

[0082] It should be noted that the specific implementation content of the navigation device of the present invention has been described in detail in the above-mentioned navigation method, so the repeated content will not be described again here.

[0083] In one embodiment, the vehicle-mounted display is a head-up display.

[0084] As another aspect, the present invention further provides a vehicle, comprising the navigation device described in the above embodiment.

For example, two boxes represented in succession can actually be executed substantially in parallel, and they can sometimes be executed in the opposite order, depending on the functions involved. It should also be noted that each box in the block diagram or flow chart, and the combination of the boxes in the block diagram or flow chart can be implemented with a dedicated hardware-based system that performs the specified function or operation, or can be implemented with a combination of dedicated hardware and computer instructions.

[0086] The units involved in the embodiments of the present invention may be implemented by software or hardware. The units described may also be set in a processor, for example, it may be described as: a processor includes a distance unit and a display unit, wherein the names of these units do not constitute limitations on the units themselves in some cases.

[0089] Since the first display mode and the second display mode are switched based on the vehicle's driving speed, and the size of the turn sign changes dynamically in the first display mode and remains unchanged in the second display mode, the size of the turn sign will not change suddenly, allowing the driver to effectively perceive the distance between the vehicle's current position and the turning intersection and the vehicle's driving speed, thereby providing a good driving assistance experience.
