In the following, a method 200 of non-destination navigation according to an embodiment of the invention will be described with reference to fig. 2.
In step 201, a real-time travel speed of the vehicle is calculated based on the positioning signal.
In one embodiment, when the user launches the navigation software, clicking the navigation button prepares to start navigation and does not set a destination. At this time, if the vehicle is in a stationary state, the navigation software always stays in the map mode.
When the vehicle starts moving, the Positioning information is acquired through a Global Positioning System (GPS) or other Positioning systems, and the real-time traveling speed of the vehicle is calculated according to the acquired Positioning information. In one embodiment, a positioning navigation service is performed using an in-vehicle GPS device or built-in GPS information provided from an internal navigation system of a terminal device, a GPS signal is received in real time, and a real-time traveling speed of a vehicle is calculated from the received GPS signal. For example, the distance between the current location and the GPS satellite may be calculated based on the GPS signal, and the current location may be inferred by trilateration to compare each distance between multiple instances of the GPS satellite and the current location, thereby calculating the traveling speed of the vehicle from the moving speed of the current location. It should be noted that, in this document, a vehicle is a general meaning, and the term "vehicle" includes not only vehicles such as vehicles, but also any vehicle or person that needs to use navigation.
In step 202, when the real-time running speed is greater than a preset value, a non-destination navigation mode is started.
In one embodiment, when the real-time driving speed is greater than a preset value and lasts for a period of time, the non-destination navigation mode is started, the map mode is exited, and a navigation page is entered. The preset value and the period of time may be set according to specific application requirements, for example, the duration may be set to several seconds or any other suitable time period. That is, if the real-time travel speed of the vehicle is greater than the preset value within several seconds, it is considered that the user needs to start navigation, whereby it is possible to avoid the navigation mode from being started when the user performs short-distance travel that does not require navigation.
Wherein the non-destination navigation mode comprises: and acquiring the navigation information of the current road, stopping inquiring the navigation information of the next road, and stopping path calculation.
Specifically, the current road name and other navigation information may be queried and prepared for later prompts used in conventional navigation, such as camera prompts, speed-over prompts, and the like. In addition, since the user does not set a destination, it is not necessary to provide navigation information other than the current road to the user and calculate a route when performing the non-destination navigation. Thus, in actual operation, the destination may be set to a null value, and only the navigation information of the current road is queried, without querying the name of the next road, and without performing the route calculation. Also, in one embodiment, the non-destination navigation mode further includes ceasing to query for turn-around information. It should be noted that when the user sets the destination, the navigation is performed in a normal navigation mode, such as performing route calculation, acquiring steering information, and the like.
In one embodiment, after the non-destination navigation mode is started, rendering the map according to the real-time running speed of the vehicle is further included. For example, a vehicle icon may be displayed on a map according to a real-time traveling speed of the vehicle, and thus, a current position and a traveling speed of the vehicle may be intuitively displayed. Illustratively, the map can be generated by rendering by a server and directly issued to a client, or the server issues formation data of the navigation map to the client and the client renders the map picture, or the client pre-stores the data and automatically generates and renders navigation data. Then, a navigation map is displayed through the client. The navigation map may be a three-dimensional navigation map and/or a two-dimensional navigation map, which is not limited herein.
In step 203, navigation is performed based on the non-destination navigation mode.
In one embodiment, navigation continues as the vehicle travels and navigation information continues to be provided. When the necessary navigation information is obtained, necessary navigation information reminding is given to the user, and guarantee is provided for safe driving. The necessary navigation information reminders include on-map reminders and voice reminders. Illustratively, the voice alert may be played on a map on a vehicle liquid crystal meter, and/or through a vehicle multimedia device. The necessary navigation information reminders include, but are not limited to, speeding, traffic signs, Point of Interest (POI) reminders, and/or radar cameras, etc.
Based on the above description, according to the destination-less navigation method of the embodiment of the present invention, it is possible to continuously provide navigation information without setting a destination, and free navigation.
Illustratively, a navigation method according to an embodiment of the present invention may be implemented in a device, apparatus, or system having a memory and a processor.
Illustratively, the navigation method according to the embodiment of the present invention may be deployed at a personal terminal such as a smartphone, a tablet, a personal computer, or the like. Alternatively, the navigation method according to the embodiment of the present invention may also be deployed at a server side (or a cloud side). Alternatively, the navigation method according to the embodiment of the present invention may also be distributively deployed at the server side (or cloud side) and the personal terminal. Alternatively, the navigation method according to the embodiment of the present invention may also be distributively deployed at different personal terminals.

For example, a vehicle icon may be displayed on a map according to a real-time traveling speed of the vehicle, and thus, a current position and a traveling speed of the vehicle may be intuitively displayed. Illustratively, the map can be generated by rendering by a server and directly issued to a client, or the server issues formation data of the navigation map to the client and the client renders the map picture, or the client pre-stores the data and automatically generates and renders navigation data. Then, a navigation map is displayed through the client. The navigation map may be a three-dimensional navigation map and/or a two-dimensional navigation map, which is not limited herein.
In one embodiment, the apparatus further comprises a prompt module. As the vehicle travels, the navigation module 320 navigates based on the non-destination navigation mode and continues to provide navigation information. When the necessary navigation information is obtained, the prompting module prompts the necessary navigation information for the user, so that the safe driving is guaranteed. The necessary navigation information reminders include on-map reminders and voice reminders. Illustratively, the voice alert may be played on a map on a vehicle liquid crystal meter, and/or through a vehicle multimedia device.
