Abstract

A vehicle display control device includes: a memory that stores a native platform for operating a native application and a versatile platform for operating a versatile application, and includes a common memory area for sharing data; a control unit that executes the versatile platform to operate a storing device for storing a versatile application image in the common memory area, executes the native platform to operate an acquisition device for acquiring the versatile application image, and operates a production device for producing a display image, in which the versatile application image and a native application image rendered by a native application are laid out; and a display control device that displays the display image on a display device.

Claims

1. A vehicle display control device comprising:

a memory that;

stores a native platform as basic software for operating a native application, which is preliminary implemented as a vehicular embedded feature, and a versatile platform as basic software, which is virtually implemented in the native platform, for operating a versatile application introduced through information communication from an outside device; and

includes a common memory area as a memory area for sharing data between the native platform and the versatile platform;

a control unit that;

executes the versatile platform so as to operate a storage device for storing a versatile application image, which is an image rendered by a running versatile application, in the common memory area;

executes the native platform so as to operate an acquisition device for acquiring the versatile application image stored in the common memory area by the storage device; and

operates a production device for producing a display image, in which the versatile application image acquired by the acquisition device and a native application image rendered by a running native application are laid out according to a predetermined display requirement defined in the native platform; and

a display control device that displays the display image, which is produced by the production device, on a predetermined display device, wherein

the production device produces a display image related to the versatile application image acquired by the acquisition device, and a display image related to the native application image rendered by the running native application as display images, which are displayed separately on a plurality of display screens, and

the display control device displays the display image related to the versatile application image produced by the production device and the display image related to the native application image, by separately distributing the display images to a plurality of display screens, respectively.

2. The vehicle display control device according to claim 1,

wherein the control unit further operates the communication device for communicating between the native platform and the versatile platform,

wherein the control unit executes the versatile platform to notify information that the storage device has stored the versatile application image in the common memory area to the native platform via the communication device, and

wherein the control unit executes the native platform so as to control the acquisition device to acquire the versatile application image, which is stored in the common memory area, under a condition that the information that the versatile application image has been store in the common memory area is notified to the native platform via the communication device.

3. The vehicle display control device according to claim 1,

wherein the control unit executes the versatile platform so as to further operate a conversion device for converting the versatile application image into an image in a predetermined format, and

wherein the production device produces a display image, in which the image, prepared by converting the versatile application image with the conversion device to have the predetermined format, and the native application image are laid out according to the display requirement.

4. The vehicle display control device according to claim 3,

wherein the control unit includes a central processing unit and image processing unit,

wherein the central processing unit operates the native platform,

wherein the image processing unit performs a calculation, which is necessary to display an image, in place of the central processing unit, and

wherein the conversion device controls the image processing unit to convert the versatile application image.

5. The vehicle display control device according to claim 1,

wherein the production device produces a display image, in which the versatile application image acquired by the acquisition device and the native application image rendered by the native application are displayed and superposed on each other.

7. The vehicle display control device according to claim 1,

wherein the control unit further operates a communication device for communicating between the native platform and versatile platform,

wherein the control unit executes the native platform so as to store an external image, which is rendered by an application in an external unit connected to the vehicle display device, in the common memory area, and to notify information that the external image has been stored in the common memory area to the versatile platform via the communication device, and

wherein the control unit executes the versatile platform so as to acquire the external image, which is stored in the common memory area, under a condition that the information that the external image has been stored in the common memory area is notified to the versatile platform via the communication device, and to feed an acquired external image to a running versatile application.

6. (canceled)

8. A vehicle display control device comprising:

a native platform as basic software for operating a native application, which is preliminary implemented as a vehicular embedded feature;

a versatile platform as basic software, which is virtually implemented in the native platform, for operating a versatile application introduced through information communication from an outside device; and

a common memory area as a memory area for sharing data between the native platform and versatile platform,

wherein the versatile platform includes a storage device that stores a versatile application image, which is an image rendered by a running versatile application, in the common memory area, and

wherein the native platform includes;

an acquisition device that acquires the versatile application image stored in the common memory area by the storage device;

a production device that produces a display image, in which the versatile application image acquired by the acquisition device, and a native application image rendered by a running native application are laid out according to a predetermined display requirement defined in the native platform; and

a display control device that displays the display image, which is produced by the production device, on a predetermined display device, wherein

the production device produces a display image related to the versatile application image acquired by the acquisition device, and a display image related to the native application image rendered by the running native application as display images, which are displayed separately on a plurality of display screens, and

the display control device displays the display image related to the versatile application image produced by the production device and the display image related to the native application image, by separately distributing the display images to a plurality of display screens, respectively.
