1 is a block diagram of a vehicle streaming control device according to an embodiment, FIG. 2 is a conceptual diagram of a vehicle control system according to an embodiment, and FIG. 3 is a diagram illustrating a display device in a vehicle control system according to an embodiment.

1 and 2, the vehicle control device 100 according to the embodiment includes a receiving unit 110, a confirmation unit 120, a determination unit 130, a comparison unit 140, a determination unit 150, and an output may include section 160 .

First, the receiving unit 110 may receive a streaming request. The streaming request may be generated by a user's input (a user's gesture such as a swipe) as will be described later. And the streaming request may include a command by an application in the vehicle control system, each operating system, and the like.

When it is determined that the streaming request is from the infotainment unit to the driving unit, the checking unit 120 may check the state of the vehicle, the display type of the streaming request, and the type of application requesting streaming. The checking unit 120 checks information related to the streaming request, and may receive and check the corresponding information from the infotainment unit or the driving unit.

The determination unit 130 may determine whether a streaming request is made from the infotainment unit to the driving unit. For example, the determination unit 130 may determine whether a streaming request is from the infotainment unit to the driving unit, a streaming request within the infotainment unit, or a streaming request from the driving unit to the infotainment unit. That is, the determination unit 130 may determine whether the streaming request is made within the infotainment unit (IP).

In addition, a streaming client in a virtual engine (virtualization environment) or an operating system (eg, a guest operating system) mounted (or embedded) in a host operating system may request streaming to a display device connected to each operating system. A streaming request means data of a streaming target and may include information on a target receiving streaming. In addition, the streaming server installed in the virtual engine or container or base operating system may provide data, that is, a streaming request to a target receiving streaming (eg, a display device or a receiving unit in a display device). At this time, the streaming request, that is, data may be transferred to the display device through a virtual engine or a streaming client in an operating system (eg, a guest operating system) mounted (or embedded) in the host operating system and provided to the user.

The comparator 140 may determine streaming execution based on the checked vehicle state, the display type of the streaming request, and the type of application requesting streaming.

Also, the comparison unit 140 may compare the priority of the receiving unit with a preset priority in the display device of the streaming request. In this specification, the priority of a streaming request is a streaming policy, and the higher the priority, the lower the limit on streaming execution. A detailed description of this will be given later.

Also, the comparator 140 may compare whether the priority of the receiving unit is higher than the predetermined priority. And, as will be described later, the decision unit 150 determines streaming execution based on this.

Also, the comparator 140 may compare whether the type of application requesting streaming is a preset type or compare the priority of the application type. And, as will be described later, the decision unit 150 determines streaming execution based on this.

Also, the comparator 140 may compare whether the priority of the receiving unit is lower than the preset priority.

Also, when a streaming request is made in the infotainment unit (IP), the comparison unit 140 may compare the priority of the receiving unit and the priority of the transmitting unit in the display device of the streaming request. In the display device, the receiving unit refers to a display device that outputs an image or the like according to the above-described user input, and the transmitting unit refers to a display device that is outputting before a user input.

Further, the determination unit 150 may determine streaming execution based on the checked vehicle state, the display type of the streaming request, and the type of application requesting streaming.

The determining unit 150 compares the priorities of the receiving units by the comparing unit 140, and determines that the priority of the receiving unit is higher than the preset priority based on the comparison to perform streaming.

In addition, the determining unit 150 may determine to execute streaming when the priority of the receiving unit is higher than the preset priority.

Also, the determination unit 150 may determine to execute streaming when the type of application requesting streaming is a preset type.

In addition, the determining unit 150 may cancel streaming execution when the vehicle state is driving in the step of determining streaming execution when the type of application requesting streaming is a preset type. That is, it is possible to easily share an application that does not interfere with driving according to the type of application.

In addition, the determining unit 150 may disallow streaming execution when the priority of the receiving unit is lower than the preset priority. Accordingly, it is possible to reduce driver's driving disturbance.

Also, the determination unit 150 may determine to execute streaming when a streaming request is not made within the infotainment unit. That is, the decision unit 150 may determine to execute streaming because there are few obstacles to driving in response to a streaming request from the driving unit to the infotainment unit.

Further, the determining unit 150 may determine to execute streaming when the priority of the receiving unit is less than or equal to the priority of the transmitting unit. In this way, it is possible to minimize the driving hazard factor.

The output unit 160 may output a streaming permission request when the priority of the receiving unit is higher than that of the transmitting unit. Accordingly, when the driver accepts the streaming permission request, the decision unit 150 may output a streaming decision.

In addition, the output unit 160 may output a streaming request, that is, data to the receiving unit when streaming is executed. For example, the output unit 160 may output data to a streaming server in the infotainment unit (IP) or driving unit (CP) or a streaming client that executes a corresponding receiving unit.

And referring to FIGS. 2 and 3 , the vehicle control system according to the embodiment includes hardware (not shown), a base operating system 10 mounted on hardware (not shown), and a base operating system 10. First virtual engine 20a and second virtual engine 20b, at least one operating system 30a to 30f mounted on each virtual engine, middleware and middleware mounted on at least one operating system 30a to 30f As a software set including important applications, a plurality of operating system platforms 40a to 40f, a plurality of applications 50a to 50d running on the operating system platforms 40a to 40f, a plurality of operating system platforms 40a to 40f, or a plurality of applications. It may include a plurality of displays 60a to 60f outputting the like. Terms described in the drawings are implementation examples of each component.

Here, hardware (not shown) may be a concept including a processor, a display unit, a storage unit, a memory unit, a control unit, and an I/O device.

In the embodiment, the driving unit CP is a system area mounted or driven on the first virtual engine 20a, and the infotainment unit IP is a second virtual engine (which is a virtual engine of a different type from the first virtual engine 20a). 20b) may be a system area mounted on or driven. With this configuration, even if an upgrade or other malfunction occurs in the infotainment unit IP, the driving unit CP may not be affected by it. That is, the influence during driving can be minimized.

First, the base operating system 10 may be, for example, various operating systems. For example, the base operating system 10 may include Linux, a hypervisor, QNX, GENIVI, and the like.

For example, the first virtual engine 20a and the second virtual engine 20b are middleware solutions or various platforms, and may be developed in the "mobile" C language. The first virtual engine 20a and the second virtual engine 20b may provide a plurality of built-in libraries, and may perform the same operation in various mobile terminals. For example, the first virtual engine 20a and the second virtual engine 20b may be a Linux-based Android kernel, and may initialize memory protection, a virtual memory module, and schedule caching.

Also, at least one container 30a to 30d may be loaded on the second virtual engine 20a and may not be loaded on the first virtual engine 10a. Accordingly, since security of the driving unit CP is improved, driving stability may also be improved.

The at least one container 30a to 30d may be a schedule of process virtualization as a form of a virtualization method in an embodiment. For example, virtualization technology using containers divides the inside of the host OS (operating system) into a kernel space that manages physical resources and a user space that executes user processes, that is, application programs (APPs, applications), and divides the user space into several parts, respectively. It may refer to a technique of allocating and sharing hardware resources used in user processes of For example, the containers 30a to 30d may convert a called library to be interfaced with a system library to perform connection or compatibility between a base operating system and a plurality of operating system platforms.

A plurality of operating system platforms 40a to 40f may be mounted on a container. The plurality of operating system platforms 40a to 40f may include Android, Automotive Grade Linux (AGL), a web platform, a cluster platform, a head-up display (HUD) platform, and the like.

The at least one application 50a to 50d is an application program other than a system program, and may include Audio Video Navigation (AVN), Co-Driver, Rear Seat Entertainment (RSE), and the like in a vehicle.

The plurality of displays 60a to 60f may display the operating system platforms 40a to 40f or application programs on the platforms to users (eg, passengers). For example, the plurality of displays 60a to 60f may include various display devices (eg, OLEDs).

In addition, each element described in the drawings is an example, and will be described below based on this.

A user (eg, a passenger) may manipulate the vehicle control system through a user interface or the like. The result of this is displayed through the display device so that the user can easily recognize the result of manipulation.

4 is a flowchart of a vehicle streaming control method according to an embodiment, and FIG. 5 is a detailed flowchart of a vehicle streaming control method in response to a streaming request from an infotainment unit to a driving unit according to an embodiment.

Referring to FIGS. 4 and 5 , the vehicle streaming control method according to the embodiment includes a receiving unit receiving a streaming request (S1100), a determining unit determining whether or not the streaming request is from the infotainment unit to the driving unit (S1200), When the confirmation unit determines that the streaming request is from the infotainment unit to the driving unit, the step of checking the state of the vehicle, the type of display of the streaming request, and the type of application requesting streaming (S1310) and the state of the vehicle confirmed by the determination unit, the streaming request It may include a step of determining streaming execution based on the type of display of and the type of application requesting streaming (S1400). In addition, the vehicle streaming control method according to the embodiment may execute streaming when it is determined to execute streaming. For example, the image on the display device of the RSE may be output from the display device of the cluster through streaming (S1800) by the output unit. In addition, in the case of disallowing streaming execution (S1900), video output may be maintained on the display device of the RSE. And it should be understood that each step may be executed in the components of the vehicle control device described above.

More specifically, the determination unit may determine streaming execution based on the confirmed vehicle state, the type of display of the streaming request, and the type of application requesting streaming (S1400).

To execute such streaming, the comparison unit may compare the priority of the receiving unit with a preset priority in the display device of the streaming request (S1410).

If the comparison unit indicates that the priority of the receiving unit in the display device of the streaming request is higher than the preset priority, the determination unit determines to execute streaming, and streaming may be executed (S1800).

Furthermore, when the comparison unit indicates that the priority of the receiving unit in the display device of the streaming request is higher than the preset priority, and the type of application requesting streaming is the preset type, the determination unit determines to execute streaming, and the streaming is executed. It can (S1800).

Further, if the comparison unit indicates that the type of application requesting streaming is not a preset type, the determination unit may determine that streaming is not allowed. Accordingly, streaming execution may be disallowed (S1900).

In addition, streaming execution or disallowance may be determined according to the state of the vehicle. As an example, if the comparator indicates that the vehicle is driving ( S1430 ), the determination unit may cancel the decision to execute streaming, and the execution of streaming may be cancelled. That is, streaming execution may be disallowed (S1900). For example, the comparison unit may set priorities for the state of the vehicle and perform comparison with preset priorities or threshold values (S1430). Then, whether or not to execute streaming may be determined by the determining unit.

In contrast, when the vehicle state in the comparator is in a state such as autonomous driving rather than driving (S1430), the determination unit may determine to execute streaming. Accordingly, streaming execution may be performed (S1800).

In addition, if the comparison unit indicates that the priority of the receiving unit in the display device of the streaming request is lower than the preset priority, the determination unit may determine that streaming is not allowed. Accordingly, streaming execution may be disallowed (S1900).

Furthermore, the confirmation unit may check information on whether or not the streaming request is from the infotainment unit to the driving unit. Based on this, the determination unit may determine whether the streaming request is made from the infotainment unit to the driving unit or within the infotainment unit (S1200).

That is, if the streaming request is not made from the infotainment unit to the driving unit, the determination unit may determine whether the streaming request is made within the infotainment unit or from the driving unit to the infotainment unit. If it is determined that the streaming request is made from the driving unit to the infotainment unit, the determination unit may determine streaming execution (S1320). Accordingly, streaming execution may be performed (S1800). That is, if a streaming request is not made inside the infotainment unit, streaming is executed.

Also, if the streaming request is made in the infotainment unit by the determination unit, the comparison unit may compare the priority of the receiving unit and the priority of the transmitting unit in the display device of the streaming request. At this time, if the priority of the receiving unit is equal to or lower than that of the transmitting unit, streaming execution may be determined (S1330). Accordingly, streaming execution may be performed (S1800).

In contrast, when the priority of the receiving unit is higher than that of the transmitting unit, streaming execution may be primarily disallowed. Also, the output unit may output a streaming permission request authorization to the driver (S1340). In contrast, when the driver or the like accepts the authorization, streaming execution may be determined and streaming execution may be performed (S1800). In contrast, when the driver or the like refuses to grant the streaming permission request, it is determined to disallow streaming, and the streaming execution disallowance may be performed (S1900).

Hereinafter, specific examples for performing each step described above will be described.

6 is a diagram illustrating vehicle streaming according to an embodiment, FIG. 7 is a diagram illustrating execution of vehicle streaming in the vehicle control system of FIG. 6 , and FIG. 8 is a vehicle streaming control apparatus or method according to an embodiment. It is a diagram explaining the priority criterion.

6 and 7, the image output from the display device 60d of the Co-Driver slides to the cluster display device 60a due to a user input (eg, Swipe), and the cluster display device 60a A streaming request to ) may be output. When the receiving unit determines to execute streaming in response to such a streaming request, the image output from the display device 60d of the Co-Driver may be streamed to the cluster display device 60a. In this case, the streaming control device according to the embodiment may be located in a driving unit, an infotainment unit, or a vehicle control system.

Referring to FIG. 8 , in the vehicle streaming control apparatus and method according to the embodiment, the driving unit may have a higher priority than the infotainment unit. In this specification, the priority means that the higher the number, the lower the priority (lower priority). For example, '0' means higher priority than '1'.

First, the driving unit may have a higher priority than the infotainment unit. As a result, stability of the vehicle driving environment by the driver may be improved.

In the infotainment unit, priorities may be lowered in the order of AVN, Co-Driver, RSE, and others. That is, the priority of each system in the infotainment unit may be determined according to the degree of relevance to vehicle driving.

In addition, the priority of the vehicle state may be lowered in the order of driving, autonomous driving, stopping, and parking. Also, the types of applications may be lowered in the order of navigation, media, video call, and others. Accordingly, disturbance of the vehicle's traveling can be easily suppressed.

Also, as an embodiment, classification may be reflected in the first column, priority within the infotainment unit may be reflected in the second column, type of application may be reflected in the third column, and vehicle condition may be reflected in the fourth column.

Hereinafter, operations of the vehicle control apparatus and method will be described based on these criteria.

9 is a diagram for explaining one operation of a vehicle streaming control device or control method according to an embodiment, FIG. 10 is a diagram for explaining another operation of a vehicle streaming control device or control method according to an embodiment, and FIG. A diagram illustrating another operation of a vehicle streaming control device or control method according to an example, FIG. 12 is a diagram illustrating another operation of a vehicle streaming control device or control method according to an embodiment, and FIG. FIG. 14 is a diagram illustrating another operation of the vehicle streaming control device or control method according to an embodiment.

Referring to FIG. 9 , a plurality of display devices of the driving unit and the infotainment unit may output different images, and the plurality of display devices may stream each other, that is, play images, etc. according to priority.

Referring to FIG. 10 , a request for streaming from the infotainment unit to the driving unit may not be made within the infotainment unit. At this time, streaming execution is determined and streaming may be performed. That is, in the case of a streaming request from the driving unit to the infotainment unit, streaming execution may be performed. For example, streaming execution may be performed without permission for a streaming request in which the cluster display device or the HUD display device is the transmitting unit and the display device of the infotainment unit is the receiving unit. As shown, the cluster display device or the HUD display device may have a priority of '0' in the first column of the display device of the infotainment unit, that is, a higher priority than '1' of the display device of the infotainment unit. Accordingly, streaming is performed, and the driver can easily set a desired driving environment while blocking driving disturbance from the occupants while driving the vehicle. For example, since the driver can be provided with a plurality of images representing various states of the vehicle at the same time, the driving environment is improved.

And the value for this priority may be applied to the header of the MJPEG packet. For example, priority information up to the fourth column may be reflected in 'mjpg'. Thus, when encoding a predetermined frame such as h.264, it is difficult to reflect the situation in the vehicle (eg, driving) in real time, but the vehicle streaming control device and method according to the embodiment encode/decode for each frame MHPEG packet header It is possible to easily perform real-time situation reflection by reflecting priorities in

Referring to FIG. 11 , when there is a streaming request from the infotainment unit to the driving unit, the state of the vehicle, the display type of the streaming request, and the type of application requesting streaming may be checked.

As described above, the streaming control apparatus and method according to the embodiment may determine streaming execution based on the checked vehicle state, the display type of the streaming request, and the type of application requesting streaming.

Streaming from the infotainment unit having a low priority in the first column to the driving unit may be limited. For example, the priority of the receiving unit in the display device of the streaming request may be compared with a preset priority. In addition, streaming execution may be determined when the priority of the receiving unit is higher than the preset priority, and streaming execution may be primarily disallowed when the priority of the receiving unit is lower than the preset priority. For example, streaming execution may be determined when the priority of the receiving unit, that is, the priority of the second column is 1 or less. This reflects the fact that streaming by the front seat of the vehicle does not significantly impair driving stability. For example, streaming may be executed for a streaming request from the AVN display 101xx or the Co-Driver display 112xx to the driving unit.

Furthermore, streaming execution may be limited according to the type of application. For example, when the type of application requesting streaming is a preset type or when the priority of the type of application is lower than the preset priority (eg, 1), streaming execution may be canceled. For example, streaming execution may be disallowed for a streaming request from the co-driver display 112xx to the driving unit.

In addition, in the step of determining streaming execution when the type of application requesting streaming is a preset type, streaming execution may be canceled when the vehicle is driving. For example, in the case of an AVN display (1010x), streaming execution may be canceled. Thus, driving stability can be greatly improved.

In addition, when the priority of the receiving unit is lower than the preset priority, streaming execution may be disallowed. That is, it may be determined to disallow streaming execution for all streaming requests from RSE display #1 (123xx) and RSE Display #2 (122xx) to the driving unit.

Referring to FIGS. 12 and 13 , a streaming request between display devices in an infotainment unit may be received. At this time, the display device of the streaming request may compare the priority of the receiving unit and the priority of the transmitting unit. As an embodiment, streaming execution may be determined when the priority of the receiving unit is less than or equal to the priority of the transmitting unit. In contrast, when the priority of the receiving unit is higher than that of the transmitting unit, streaming may be disallowed without determining execution.

For example, a streaming request from an AVN display (101xx) or a Co-Driver Display (112xx) to RSE display #1 (123xx) or RSE Display #2 (122xx) may be determined as streaming execution. In addition, a streaming request from the AVN display 101xx to the Co-Driver Display 112xx may be determined as a streaming execution. In addition, a streaming request between RSE display #1 (123xx) and RSE Display #2 (122xx) may be determined as streaming execution.

However, streaming requests from RSE display #1 (123xx) and RSE Display #2 (122xx) to AVN display (101xx) or Co-Driver Display (112xx) are not determined as streaming execution. That is, a streaming request may be disallowed.

In addition, when the priority of the receiving unit is higher than that of the transmitting unit, a streaming permission request may be output. The streaming permission request may be output to the receiving unit. For example, when a streaming request from RSE display #1 (123xx) or RSE Display #2 (122xx) to AVN display (101xx) or Co-Driver Display (112xx) is received, a streaming permission request may be output. At this time, when the user of the receiving unit accepts the permission request, streaming execution may be performed. On the other hand, if the streaming permission request is not accepted, it may be determined that streaming is not allowed.

The above-described embodiments of the present invention may be implemented in the form of a recording medium including instructions executable by a computer, such as program modules executed by a computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. Also, computer readable media may include computer storage media. Computer storage media may include both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data.

In addition, the vehicle software control device described in this embodiment may be implemented as a computer program stored in a computer-implementable storage medium.
