Detailed Description

Fig. 1 is a block diagram of an in-vehicle apparatus according to an embodiment of the present invention. Referring to fig. 1, the in-vehicle apparatus 100 includes a processor 110, an instrument panel 120, and a storage unit 130. Processor 110 is coupled to dashboard 120 and storage unit 130.

The processor 110 is, for example, a central processing unit (Central Processing Unit, CPU), a physical processing unit (Physics Processing Unit, PPU), a programmable Microprocessor (Microprocessor), an embedded control chip, a digital signal processor (Digital Signal Processor, DSP), an application specific integrated circuit (Application Specific Integrated Circuits, ASIC), or other similar device.

The storage unit 130 is, for example, any type of fixed or removable random access Memory (Random Access Memory, RAM), read-Only Memory (ROM), flash Memory (Flash Memory), hard disk, or other similar device or combination of these devices. The storage unit 130 includes a picture database 131, and the picture database 131 includes a plurality of pictures. The storage unit 130 further includes one or more program code segments, and after the program code segments are installed, the processor 110 performs the following display method applied to the dashboard.

Fig. 2 is a flowchart of a display method applied to a dashboard in accordance with an embodiment of the present invention. Referring to fig. 1 and 2, in step S205, a picture database 131 is provided. The picture database 131 includes a plurality of picture files. The drawing file is provided with a group of cutting drawings, the group of cutting drawings respectively comprise a plurality of pointer design drawing files, and the pointer design drawing files respectively have pointers corresponding to different extending directions.

For example, fig. 3 is a schematic diagram of a pointer design drawing according to an embodiment of the present invention. FIG. 4 is a schematic diagram of a set of cut-away views in accordance with an embodiment of the present invention. In fig. 3, N pointers of the N pointer design files 301_1 to 301_n and N Zhang Zhizhen design files 301_1 to 301_n included in a set of cut figures respectively correspond to different directions. In fig. 4, N pointer design files 301_1 to 301_n included in a set of cut-out diagrams are simultaneously displayed. Here, one pointer design drawing corresponds to one angle. Taking the pointer of the hour meter as an example, assuming that the highest speed of the hour meter is 190km/h and each unit is 1km/h, by using the method, 191 and Zhang Zhizhen design files respectively pointing to angles corresponding to 0-190 km/h can be cut out. The pointers of each pointer design drawing file in a set of cut drawings correspond to an angle.

In this embodiment, the processor 110 may further determine the number of the graphics files included in the set of cut graphics stored in the graphics database 131 according to the setting parameters. The set parameter is, for example, at least one of acceleration performance, exhaust gas amount, energy consumption, and operation mode of the engine. In addition, the processor 110 may divide the speed table into a plurality of speed intervals, and the number of the graphics files corresponding to each speed interval is the same or different.

For example, the processor 110 sets the number of graphics for each speed section according to the acceleration performance of the engine, for the speed section 0-20 km/h, the speed section 20-40 km/h, the speed section 40-60 km/h, the speed section 60-100 km/h, and the speed section 100-180 km/h. For example, the number of the drawing files in the speed interval of 0-20 km/h is 20, the number of the drawing files in the speed interval of 20-40 km/h is 40, the number of the drawing files in the speed interval of 40-60 km/h is 40, the number of the drawing files in the speed interval of 60-100 km/h is 40, and the number of the drawing files in the speed interval of 100-180 km/h is 40. However, the above is only illustrative, and not limiting.

In addition, the number of the graphics files can be determined according to the acceleration performance. For example, for a vehicle type with high acceleration performance, since it can accelerate to a desired speed quickly, the change of the pointer is not required to be too precise for a low speed section (for example, 0 to 60 km/h), and a small number of drawing files can be provided. For example, the number of the drawing files in the speed interval of 0-20 km/h is 10, the number of the drawing files in the speed interval of 20-40 km/h is 20, the number of the drawing files in the speed interval of 40-60 km/h is 20, the number of the drawing files in the speed interval of 60-100 km/h is 40, and the number of the drawing files in the speed interval of 100-180 km/h is 40. However, the above is only illustrative, and not limiting.

For another example, for a vehicle with low acceleration performance, since it takes a while to accelerate to a desired speed, more graphics files can be set in a lower speed section (for example, 0-60 km/h), so that the change of the pointer can be finer. For example, the number of the drawing files of the speed interval of 0-20 km/h, 20-40 km/h, 40-60 km/h, 60-100 km/h and 100-180 km/h is set to 40. However, the above is only illustrative, and not limiting.

In addition, the drawing file of the image database 131 may also include two or more sets of cut drawings. The user can design at will and input the designed multi-cut pictures into the picture database 131 of the in-vehicle apparatus 100. For example, the drawing files include a first set of cut-out drawings and a second set of cut-out drawings, the first set of cut-out drawings and the second set of cut-out drawings respectively include a plurality of pointer design drawing files, and the pointer design drawing files respectively have pointers corresponding to different extending directions. The first group of cutting pictures and the second group of cutting pictures are pointer design pictures with different styles. The processor 110 may determine to fetch the pointer design drawing file in the first set of cut drawings or fetch the pointer design drawing file in the second set of cut drawings from the picture database 131 based on the setting instruction. The setting instruction may be preset or may be input by a user. For example, a pointer pattern of each display content (for example, a hour meter, an oil meter, a tank thermometer, an engine thermometer, etc.) in the dashboard 120 may be set in the in-vehicle apparatus 100 in advance. Alternatively, various pointer patterns in the dashboard 120 may be set by the user.

For example, fig. 5 is a schematic diagram of a pointer pattern according to an embodiment of the present invention. Pointer patterns 501, 503, 505, 507, 509 are listed in fig. 5. Five cut-graphs may be set in the picture database 131 for five pointer patterns 501, 503, 505, 507, 509. The processor 110 sets a set of cut charts corresponding to the respective display contents based on the setting instruction. The pointer patterns used for the respective display contents may be the same or different.

After the picture database 131 is established, the processor 110 reads the driving data in step S210. In step S215, the processor 110 retrieves a drawing corresponding to the driving data from the image database 131 according to the driving data. After obtaining the driving data, the processor 110 fetches the image file corresponding to the driving data from the image database 131. For example, the driving data is at least one of a driving speed, an oil amount, a water tank temperature, and an engine temperature. Taking the driving data as the driving speed for example, after obtaining the current driving speed of 40km/h, the processor 110 will take out a drawing corresponding to 40km/h from a group of cut drawings corresponding to the display content of the hour meter in the picture database 131.

Then, in step S220, the processor 110 displays the fetched drawing file at a specific position corresponding to the dashboard 120. For example, assuming that the traveling speed is 40km/h, the processor 110 fetches a drawing file corresponding to 40km/h in the direction pointed by the pointer from the picture database 131, and displays the fetched drawing file in a specific position corresponding to 40km/h in the hour meter of the dashboard 120.

In addition, the processor 110 may vary the pointer pattern presented by the hour meter as the vehicle speed varies. Fig. 6 is a schematic diagram of a hour meter using a pointer pattern in accordance with an embodiment of the present invention. Fig. 7 is a schematic diagram of a hour meter using another pointer pattern in accordance with an embodiment of the invention. For example, when the speed per hour is less than or equal to 100km/h, a pointer design drawing file of a pointer pattern 509 as shown in fig. 6 is displayed. When the speed per hour is greater than 100km/h, a pointer design drawing file of a pointer pattern 507 as shown in fig. 7 is displayed.

In addition, the instrument panel 120 design can have not only a fixed elliptical boundary, but also other options. For example, the user may input his/her own design drawing or favorite drawing as a boundary drawing of the dashboard 120, as shown in fig. 8. FIG. 8 is a schematic diagram of a customized dashboard boundary map in accordance with an embodiment of the present invention.

In addition, in other embodiments, the image file further includes at least one set of images, the set of images including a plurality of cut-out images, the stereoscopic effect being exhibited by continuously displaying the plurality of cut-out images in the set of images. Here, the group map may be stored in advance in the picture database 131. In addition, the existing image files in the image database 131 can be used to generate a plurality of cut images to form a group image. For example, the processor 110 may select one of the image files from the image database 131 as a reference image file, zoom the reference image file according to the requirement to obtain a plurality of cut images with different sizes, or rotate the reference image file according to the requirement to obtain a plurality of cut images with different directions.

In step S220 shown in fig. 2, the processor 110 may further continuously display the cut map included in the group map at a specific position. The processor 110 can change or stack different cut patterns according to different time, speed and direction, thereby creating a three-dimensional stereoscopic effect. In addition, a playing speed can be further preset, or the playing speed can be determined according to the currently obtained driving data, so that different cutting pictures can be replaced or stacked according to the playing speed. For example, the faster the travel speed, the faster the play speed, the slower the travel speed, and the slower the play speed. However, the present invention is not limited to the above examples.

In addition, the processor 110 may number the group graph, and number each cut graph in the group graph, and set a usage scenario corresponding to the group graph according to the requirement. For example, it is assumed that the group diagram numbers include 3d_1, 3d_2, that the group diagram number 3d_1 includes the cut diagram numbers 2d_1 to 2d_10, that the group diagram number 3d_2 includes the cut diagram numbers 2d_11 to 2d_20, that the group diagram number 3d_1 corresponds to the night mode, and that the group diagram number 3d_2 corresponds to the day mode. When the dashboard 120 is set to the daytime mode, the processor 110 selects the group map number 3d_2 to display the cut maps corresponding to the cut map numbers 2d_11 to 2d_20 in the positions corresponding to the dashboard 120. When the instrument panel 120 is set to the night mode, the processor 110 selects the group drawing number 3d_1 to display the cut drawings corresponding to the cut drawing numbers 2d_1 to 2d_10 in the position corresponding to the instrument panel 120.

FIG. 9 is a schematic diagram of a group diagram in accordance with an embodiment of the present invention. Referring to fig. 9, group diagram 900 includes cut diagrams 901 to 906. Here, the cut-out 901 to the cut-out 906 are different in size, and the cut-out 901 to the cut-out 906 exhibit a stereoscopic effect that gradually increases as seen from the viewing angle direction D1. The processor 110 displays the stereoscopic effect by continuously displaying the cut-out images 901 to 906 in the group of images 900 at a specific position of the dashboard 120 based on the playing speed, for example, the cut-out images 902, 903, 904, 905, 906 are sequentially displayed from the smallest cut-out image 901 based on the size.

Here, the cut pictures 901 to 906 may be created in advance in the picture database 131, or the cut pictures 901 to 906 may be generated based on the stereoscopic effect to be presented according to a reference picture file. And, the number of cut graphs included in the group graph 900 may be dynamically determined according to the resolution.

FIG. 10 is a schematic diagram of a group diagram in accordance with an embodiment of the present invention. Referring to fig. 10, group diagram 1000 includes cut diagrams 1001 to 1005. Here, the cut patterns 1001 to 1005 have different sizes. The processor 110 starts to display from the smallest cut 1001 in a specific position of the dashboard 120 based on the play speed, and then sequentially displays the cut 1002, the cut 1003, the cut 1004, and the cut 1005, thereby presenting a stereoscopic effect gradually increasing from the viewing angle direction D2. Here, the cut patterns 1001 to 1005 may be created in advance in the picture database 131, or the cut patterns 1001 to 1005 may be generated based on the stereoscopic effect to be presented according to a reference picture file. And, the number of cut graphs included in the group graph 1000 may be dynamically determined according to the resolution.

FIG. 11 is a schematic diagram of a group diagram in accordance with an embodiment of the invention. Referring to fig. 11, the group diagram 1100 includes cut diagrams 1101 to 1112, and the cut diagrams 1101 to 1112 exhibit a clockwise rotation effect. In this embodiment, the patterns (i.e., "99") included in each of the cut patterns 1101 to 1112 are different. In other words, two of the cut-out images are superimposed on each other and then form a rotated image relationship based on the same center point. For example, in the view of the cut charts 1101 and 1102, the pattern "99" of the cut chart 1102 is obtained by rotating the pattern "99" of the cut chart 1101 clockwise by an angle; in view of the cut patterns 1101 and 1112, the pattern "99" of the cut pattern 1112 is obtained by rotating the pattern "99" of the cut pattern 1101 counterclockwise by a certain angle. Thus, cut patterns 1101 to 1112 having different pattern directions can be obtained. Here, the cut charts 1101 to 1112 may be created in advance in the picture database 131, or the cut charts 1101 to 1112 may be generated based on the stereoscopic effect to be presented according to a reference picture file. And, the number of cut graphs included in the group graph 1100 may be dynamically determined according to the resolution.

In summary, the invention presents the driving data on the instrument panel in the mode of the drawing file map, so that the designer can bring the creative into play as much as possible, and is helpful for grasping the attractiveness of consumers and markets. Compared with the traditional mode, namely, the mode that each pixel data of the image is obtained by calculating according to the driving data by hardware and then is input into the display device for display is needed, the driving data is displayed by the multi-group cut map stored in the picture database by the mode of the embodiment, and the hardware specification can be reduced. Therefore, the method can be applied to the pointer design of multiple choices, and also considers the cost of hardware specification. In addition, the stereoscopic effect is achieved by using the mode of replacing and cutting the pictures, so that the storage space of the stereoscopic design pictures can be saved.
