1, the vehicle system 10 according to the embodiment may also be a vehicle infotainment system. The vehicle system 10 includes a vehicle console operating system associated with the user's use, a mobile operating system associated with user use of the mobile environment, and a terminal environment associated with user use of the mobile environment, ). ≪ / RTI >

The vehicle system 10 according to an embodiment may include hardware 110, a kernel 120, a system library 130, a connection 140, and an application 150.

Referring to FIG. 3, the hardware 110 may be an exemplary hardware 110 architecture of the vehicle system 10, according to an embodiment. Generally, the hardware 110 may include a processor 111, a display unit 112, a storage unit 113, a memory unit 114, a control unit 115, and an I / O device 116.

The processor 111 may be a vehicle infotainment-based processor 111. For example, processor 111 may include an ARM-based processor 111 such as Texas Instruments OMAP3430, Marvell PXA320, Freescale iMX51 or Qualcomm QSD8650 / 8250. The processor 111 may also be another suitable ARM based processor 111 based on another processor 111 architecture, such as, for example, an x86 based processor 111 architecture or other RISC based processor 111 architecture. However, the present invention is not limited to this configuration.

The display portion 112 may be a touch screen display. Also, the application 150 running in the vehicle can be controlled by a graphical user interface (GUI) on the display.

The storage unit 113 may store system files and the like, and the memory unit 114 may process and store information on predetermined files and control signals.

The control unit 115 can control various devices and components in the vehicle. For example, the control unit 115 can control the touch screen display.

I / O device 116 may include a port (not shown) or a button (not shown) and other user interface components that may be employed in vehicle system 10. For example, the button may include a click wheel, a scroll wheel, a QWERTY keyboard, and the like. Other user interface components may also include GPS devices, LAN connectivity, microphones, speakers, cameras, accelerometers, MS / MMC / SD / SDIO card interfaces, and the like. However, the present invention is not limited to this configuration.

In addition, the hardware 110 may include various interface components such as a power supply 117, a communication device, and the like in addition to the above components. For example, the power supply unit 117 may be connected to a battery. Thus, the power supply unit 117 can receive information on the electrical state and the like from the battery. With this configuration, the power supply unit 117 can manage the power supply of the vehicle system 10. [

Referring to FIG. 4, the kernel 120 may be connected to the hardware 110 to provide a control signal to the hardware 110. The hardware 110 may perform a function according to a control signal received from the kernel 120.

In the vehicle system 10, the kernel 120 may execute an operating system. That is, the operating system may be run on the kernel 120. Specifically, the operating system may be interfaced with the hardware 110 via the kernel 120. For example, the vehicle system 10 may request the kernel 120 to allow the kernel 120 to manage the computer resources of the hardware 110, such as CPU scheduling, memory access, and I / O of the operating system . In addition, the operating system may be an operating system of vehicle infotainment. For example, the operating system may be any one of QNX, GENIVI, and AGL, but is not limited thereto.

In addition, even if the hardware 110 is not present, the system call can be performed through the kernel 120 interface without virtual memory or I / O access by virtualization. However, the present invention is not limited thereto.

Also, in the embodiment, the kernel 120 may be a Linux-based Android kernel. The Android kernel may include a display driver 121, a camera driver 122, a communication driver 123, and a shared memory 124. For example, the communication driver 123 may include a Wi-Fi driver and a Bluetooth driver.

The kernel 120 may initialize the driver for the hardware 110 device. In this case, the kernel 120 may initiate memory protection, virtual memory modules, and schedule caching. Also, the kernel 120 may initialize the operating system. In an embodiment, the kernel 120 may execute the processes of the vehicle system 10 to read a configuration file describing system services and additional system parameters for the Android-based operating system.

In addition, the kernel 120 according to the embodiment can execute the Android-based application 150 on the kernel 120 simultaneously or independently. Accordingly, the Android application can be executed in the vehicle system 10 according to the embodiment. And control signals may be provided to the hardware 110 through the kernel 120 without virtualization through the application 150. [ In addition, the application 150 may be displayed on the display of the hardware 110. The user may then access the operating system via input (e.g., a touch on the touch screen) on the display. For example, a user may access the operating system on the kernel 120 using a graphical user interface (GUI).

The system library 130 may be located on the kernel 120 and may ultimately provide a request from the application 150 to the kernel 120. As described above, the kernel 120 may transmit a request from the application 150 to the hardware 110 to control the hardware 110. [ Here, the request transmitted by the kernel 120 to the hardware 110 may be the control signal.

And the operating system may be an administrator applied to the vehicle system 10. For example, in the case of a laptop, the operating system may include Linux, Mac OS X, Windows 7, and the like. In addition, mobile operating systems can include Android, Apple iOS (for iPhone and iPad), Microsoft Windows Mobile (for Windows Phone 7), Nokia Symbian and Palm OS (for HP webOS).

However, the operating system running on the kernel 120 of the vehicle system 10 may differ from the operating system of the laptop or mobile operating system due to the different environment of the application 150 executed for each system. Thus, there may be a limitation that the application 150 running on the mobile operating system is performed on the vehicle system 10. [

Referring to FIG. 2, the connection unit 140 of the vehicle system 10 according to the embodiment may include an application library 141, a conversion unit 142, and a transfer unit 143.

The application library 141 includes a library required to execute the application 150, and when the application 150 is executed, a necessary library can be called. For example, application library 141 may implement common functions such as I / O and string manipulation (e.g., " C library "), graphics library, database library, communication library and other libraries for executed application 150 . The application library 141 may provide the called library to the converting unit 142. [

The conversion unit 142 may receive the called library and convert the received library into an interface with the system library 130.

For example, the conversion unit 142 may convert the library called in accordance with the system library 130 of the vehicle system 10. And the operating system of the vehicle system 10 and the operating system executable by the application 150 may be Linux based.

For example, if the application 150 is run on Google's Android operating system, Android based on Linux will have a modification to the vehicle system 10 environment (system library 130) and the kernel 120 . And, as described above, the vehicle system 10 can use the Linux-based kernel 120.

As such, the Linux kernel may be designed with a different underlying processor 111 than the Android kernel, but it may be identical to the Linux based design. Accordingly, the converting unit 142 converts the application 150, which is executed on the Android-based basis, into mobile hardware (including a touch screen, mobile connection (GSM / EDGE, CDMA, Wi-Fi, etc.), battery management, GPS, 110 to the system library 130 of the vehicle system 10.

In addition, the library converted in the conversion unit 142 can be transmitted as a control request to the hardware 110 through the system library 130 and the kernel 120. The hardware 110 may be controlled according to a control request.

The kernel 120 receives the control result from the hardware 110 and transfers the control result to the system library 130 and transfers the control result to the transfer unit 143 as a library for the control result transferred from the system library 130 Lt; / RTI > The transfer unit 143 transfers the library of the control result to the converting unit 142 and the converting unit 142 may convert the library of the transferred control result to the application library 141. [ That is, the library of the control result is converted into an interface of the application library 141, the control result for the hardware 110 can be transferred to the application 150, and can be provided to the user on the display.

The transfer unit 143 may transfer the converted library to the system library 130. Also, the transfer unit 143 can receive the library of the control result as described above.

The vehicle system 10 according to the embodiment executes the application 150 without a virtual machine between the operating system of the application 150 in which the difference exists in the kernel 120 and the operating system of the vehicle system 10, It is possible to control the hardware 110 of the computer 10.

The vehicle system 10 according to the embodiment is not driven by the virtual machine or the hypervisor on the system library 130 via the connection 140. [ The virtual machine or hypervisor may be directly run on the hardware 110 and run through the separate kernel 120 of the operating system. For example, a hypervisor or a virtual machine effectively creates a plurality of virtual machines in one device, so that each operating system may have a separate virtual machine. Thus, multiple operating systems running on the same device through the hypervisor and the virtual machine can be run in the guest operating system rather than the kernel 120 of the vehicle system 10. [ Because it is implemented by virtualization, system overhead can be added for each operating system. Also, because the hypervisor needs to allocate CPU and other computing resources, there is a problem that each operating system can not effectively schedule processes and tasks. Accordingly, the vehicle system 10 according to the embodiment can effectively perform processes and tasks as well as execute system performance on the kernel 120 of the vehicle system 10 without virtualization of the hardware 110 resources.

5 is a flow chart of a method of controlling an application of a vehicle system according to an embodiment

Referring to FIG. 5, a method of controlling an application of a vehicle system according to an embodiment includes executing an application (S310), generating a control signal in accordance with a system library at a connection unit (S320), transmitting a control signal to a kernel (S330), controlling the hardware according to the control signal (S340), and transmitting the control result to the application (S350).

As described above, the application can be executed by the user. For example, the application may be a mobile app. And applications can run on the Android operating system.

Control signals can be generated at the connection after application execution. Specifically, the request can be transmitted to the connection unit by execution of the application. The connection unit can call the application library at the request of the application as described above. Accordingly, the application library can provide a called library including a character string, etc. to the conversion unit.

The conversion unit receives the called library and converts the received library to interface with the system library of the vehicle system, and the transfer unit can transfer the converted library to the system library.

Then, the converted library can be transferred from the system library to the control signal according to the operating system of the vehicle system and transferred to the kernel, and the kernel can control the hardware according to the control signal.

The kernel then receives control results from the hardware, passes control results to the system library, and can be passed to the delivery as a library of control results passed to the system library. Then, the transfer unit transfers the library of the control result to the conversion unit, and the conversion unit can convert the library of the transferred control result to the application library
