Description
Technical Field
The application relates to the technical field of navigation, in particular to a navigation method based on a three-dimensional scene, and a navigation device and a vehicle adopting the navigation method based on the three-dimensional scene.
Background
At present, the purchase rate of automobiles is higher and higher, so that the safety of automobiles also becomes a very important problem. In recent years, map display devices typified by navigation devices have been increasingly popular, and related technologies have been advanced. Among them, recent navigation devices can perform split display (for example, display in a left-right double screen) with an increase in the size of a display screen and an improvement in resolution. Therefore, the user can obtain more information from the navigation device and enjoy better visual experience.
For example, patent document 1 discloses a navigation device having a split-screen display function. The navigation device disclosed in patent document 1 divides a display screen into two left and right divided screens in a display mode in which the traveling direction is upward (heading up), displays a map around the current location of the vehicle on one divided screen, and displays a map at a position further forward (above the display screen, i.e., in the traveling direction of the vehicle) on the other divided screen, thereby expanding the display range of the map on the traveling direction side of the vehicle.
However, as the display mode of the navigation device, a display mode in which a predetermined direction is upward, for example, north direction (northup) is upward is often used in addition to the upward traveling direction. Patent document 1 is obviously not applicable to such a display mode in which the predetermined direction is upward.
For example, it is assumed that in the conventional map display mode with the north direction facing upward, the vehicle travels from west to east, i.e., from left to right on the display screen. In this case, if the display screen is divided into two left and right divided screens according to the technique of patent document 1 and the maps around the current location of the vehicle and on the traveling direction side are displayed on the two divided screens, respectively, the display range of the map on the traveling direction side of the vehicle cannot be expanded as compared with the case of the single-screen display. On the contrary, the split-screen display at this time causes unnecessary interference to the user and also causes an unnecessary increase in the processing load of the navigation device.
On the other hand, when a user navigates, the path switching is often performed, but the interface of the existing navigation equipment is not friendly when switching, switching is performed without any prompt, and experience is poor.

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 one embodiment, the network connection for the vehicle networking system may be a switch, which may have AVB functionality (Audio Video brightening, meeting the IEEE802.1 set of standards), and/or may include one or more unshielded twisted pair wires, each of which may have an 8P8C module connector.
In a preferred embodiment, the vehicle networking system specifically comprises a vehicle body control module BCM, a power bus P-CAN, a vehicle body bus I-CAN, a combination meter CMIC, a chassis control device and a vehicle body control device.
In this embodiment, the body control module BCM may integrate the functions of the car networking gateway to perform signal conversion, message forwarding, and the like between different network segments, i.e., the power bus P-CAN and the body bus I-CAN, for example, if a processor connected to the power bus needs to communicate with a processor connected to the body bus I-CAN, the body control module BCM may perform signal conversion, message forwarding, and the like between the two processors.
The power bus P-CAN and the vehicle body bus I-CAN are respectively connected with a vehicle body control module BCM.
The combination instrument CMIC is connected with a power bus P-CAN, and the combination instrument CMIC is connected with a vehicle body bus I-CAN. Preferably, the combination meter CMIC of the present embodiment is connected to different buses, such as a power bus P-CAN and a vehicle body bus I-CAN, and when the combination meter CMIC needs to acquire processor information that is attached to any bus, it is not necessary to perform signal conversion and message forwarding through a vehicle body control module BCM, so that gateway pressure CAN be reduced, network load CAN be reduced, and the speed of acquiring information by the combination meter CMIC CAN be increased.
The chassis control device is connected with the power bus P-CAN. The vehicle body control device is connected with a vehicle body bus I-CAN. In some examples, the chassis control device and the vehicle body control device CAN respectively broadcast data such as information to the power bus P-CAN and the vehicle body bus I-CAN, so that other vehicle-mounted processors and other devices hung on the power bus P-CAN or the vehicle body bus I-CAN CAN acquire the broadcast information, and communication between the vehicle-mounted devices such as different processors is realized.
In addition, in the car networking system of the vehicle of the embodiment, two CAN buses, namely a power bus P-CAN and a car body bus I-CAN, CAN be used, the car body control module BCM is used as a gateway, and the structure that the combination instrument CMIC is connected with both the power bus P-CAN and the car body bus I-CAN is adopted, so that the operation that information of a chassis control device or a car body control device is forwarded to the combination instrument CMIC through the gateway when the combination instrument CMIC is hung on one of the two buses in the traditional mode CAN be omitted, therefore, the pressure of the car body control module BCM as the gateway is relieved, the network load is reduced, and information of vehicle-mounted equipment hung on a plurality of buses, such as the power bus P-CAN and the car body bus I-CAN, CAN be sent to the combination instrument CMIC for display and the information transmission is strong in real-time.
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.
