It is obvious that various intelligent hardware used by the ADAS function can be accessed to the car networking system by means of an ethernet link to realize communication connection and interaction.
The host computer of the present embodiment vehicle may comprise suitable logic, circuitry, and/or code that may enable operation and/or functional operation of the five layers above the OSI model (Open System Interconnection, Open communication systems Interconnection reference model). Thus, the host may generate and/or process packets for transmission over the network, and may also process packets received from the network. At the same time, the host may provide services to a local user and/or one or more remote users or network nodes by executing corresponding instructions and/or running one or more applications. In various embodiments of the present application, the host may employ one or more security protocols.
In some specific application examples of the application:
the user says about the navigation equipment/car machine equipment: "hotel goes to the middle mountain tomb, helps me navigation view sightseeing route", navigation equipment/car machine equipment feedback: 'good, best sight path, time is more than 15 minutes, but you can appreciate Nanjing city wall and temple, and Jiangjiang stone is given to French phoenix tree of Song American age, which is very beautiful'.
In this way, when the navigation device performs path planning, the driving complexity of the road can be considered, for example, the situations of more trucks, more road bumps and more dust are considered, and sometimes, a user is difficult to pass through certain scenic areas, so that the navigation device can help the user to drive the road with the best landscape in the area.
Specifically, the present embodiment may include the following processing procedures:
1. the navigation equipment or the vehicle equipment can collect front and rear cameras of the vehicle, shoot and upload scenery along the way, wherein repeated videos or pictures can be removed;
2. the embodiment can collect a large amount of video picture data uploaded by other users and analyze the data, wherein the analysis can be carried out by the server;
3. when the picture videos are uploaded, positions and tracks can be provided at the same time, so that when the video pictures are analyzed, the landscapes of the roads are graded and compared;
4. in addition, the method and the device can also directly analyze and score according to the pictures through the panoramic photos on the current map;
5. and in the process of path planning, a higher ranking weight is given to the scenic road, and meanwhile, the running time of the road is compared with the running time of the fastest path, so that the optimal path is given to the user under the condition that the time is not increased too much.
Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being included within the following description of the preferred embodiment.
