2. use the virtual instrument technology, make the upgrading of auto meter become convenient, quick;
3. this virtual instrument system can be shown to navigation map data output on the virtual instrument; So just can be presented at the auto navigation that in other system, to realize originally on the gauge panel intermediate virtual instrument; Both provided cost savings; Simultaneously remove the driver again from, reduced the possibility that safety misadventure takes place at the navigating instrument of seeing back and forth on the run on the console;
4. the utility model will be stored the video data of nearest a period of time in the car running process, for traffic accident provides the failure-free foundation;
5. the utility model will be loaded onto the dead angle camera on automobile, and the camera input is presented at above the middle screen of gauge panel, increase driver's the visual field greatly, reduce the possibility of accident.
Description of drawings:
Fig. 1 is the utility model system architecture diagram.
The specific embodiment
As shown in Figure 1, this is based on the virtual instrument system of automobile bus, mainly comprises the host computer system module of main processing data flow medium, main processing external communication and the slave system module of signal conditioning, a display module of handling the video demonstration.Said host computer system module comprises video and pattern process module, video compress decompression module, video storage module, audiofrequency output module, button control module, communication module; Said slave system module comprise stepping backlight with functional indicator light control, sensor signal processing, CAN and LIN module, and with the master chip communication module; Said display module mainly shows the virtual instrument image, and from the host computer system module, obtains video data, then its output is shown on the display equipment.
As shown in Figure 1; Wherein the host computer system module mainly is responsible for the processing of multi-medium data; It can receive the vehicle body information that navigation data, camera data and slave system module send over; And these information are handled the display interface that forms virtual instrument, send to display module then and show; Simultaneously the host computer system module also can be preserved relevant video data and automobile correlation parameter to video data memory module (these data can become a kind of authority where necessary); According to the vehicle body data that slave system sends, the host computer system module also can be exported some voice prompts to power amplifier.
As shown in Figure 1, wherein the slave system module mainly is responsible for external communication and Signal Processing, comprises with the data exchange of vehicle-mounted bus (CAN, LIN, FlexRay etc.), obtains sensing data, process user key information and other extraneous informations etc.The slave system module is not cut off the power supply generally speaking, when automobile is not activated, is in sleep state, and power consumption is extremely low.
As shown in Figure 1, display module is responsible for the video data that shows that the host computer system module sends over, and display mode is not fixed, and can be that LCD screen (liquid crystal display) shows, outer projections or video data output is gone with the mode of video flowing.
During use, behind the automobile starting, being in dormant slave system can be waken up; Control starts the host computer system module then; The host computer system module receives and handles the data that the slave system module sends over, and begins to show virtual instrument, because whole instrument shows on read-out; So virtual instrument is except showing traditional instrumented data; Can also guarantee multimedia messages such as show navigator cartographic information under the situation that necessary vehicle body information be able to show, dead angle video information, panorama reversing video information, the demonstration of these information is can program pre-designed, also can be that the user passes through the menu place and triggers.The display mode of said information is a design-calculated arbitrarily, can show that the mode that also can use virtual pointer instrument shows or other any ways can as long as realize on the read-out with digital mode like the demonstration of speed, rotating speed.The video storage function also is activated after automobile starting; System will store nearest a period of time the video data of (length of time is confirmed by storage equipment space size); The video of overtime will be deleted, and the user can avoid being deleted by the system through the video that custom menu is preserved usefulness.
Behind the automobile flameout, display module and host computer system module will be de-energized, and the slave system module can be got back to sleep state.Dormant slave module in particular cases also can be waken up at some, and at this moment it will handle the good order of some program designs.
The mode of this virtual instrument system display automobile information is diversified, is unrestricted basically, so on virtual instrument, can come display automobile information with more lively, understandable mode, such as some animation prompt facilities or the like; When these display modes need change, only need upgrade to software when will change display interface in other words simultaneously, hardware can remain unchanged, and these advantages are that original mechanical type instrument and electronic instrument are irrealizable.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, all belong to the protection domain of the utility model.
