Abstract

A method for controlling a mobile device engaging with a head unit of vehicle includes executing a vehicle engagement application installed in the mobile device, determining first and second spaces having the same size in a frame buffer, monitoring whether a first data responsive to an execution of the vehicle engagement application is written in the first and second spaces, and if the first data is not written in the first and second spaces, performing an autonomous recovery process for the vehicle engagement application.

Claims

1. A method for controlling a mobile device engaging with a head unit of vehicle, the method comprising:

executing a vehicle engagement application installed in the mobile device;

determining first and second spaces having the same size in a frame buffer;

monitoring whether a first data responsive to an execution of the vehicle engagement application is written in the first and second spaces; and

when the first data is not written in the first and second spaces, performing an autonomous recovery process for the vehicle engagement application,

wherein the determining first and second spaces comprises;

initializing a predetermined space where the first and second spaces are located in the frame buffer; and

delivering addresses corresponding to the first and second spaces included in the predetermined space into the vehicle engagement application.

2. The method according to claim 1, further comprising:

delivering an event corresponding to a given input into the vehicle engagement application;

checking whether a second data corresponding to the given input is included in at least one of the first and second spaces; and

according to a checking result about the second data, performing the autonomous recovery process for the vehicle engagement application.

3. The method according to claim 1, wherein the performing an autonomous recovery process comprises:

analyzing an error occurring in the vehicle engagement application;

requesting addition resources when the error is relevant to a lack of resources; and

restarting the vehicle engagement application in response to the error.

4. The method according to claim 3, wherein the performing an autonomous recovery process further comprises:

assigning, by a processor included in the mobile device, a high priority for allocating available resources to the vehicle engagement application.

5. The method according to claim 1, further comprising:

converting information including the first data written in at least one of the first space and the second space into a predetermined format transferable via a network; and

showing the information on a screen.

6. The method according to claim 5, wherein the network couples the head unit and the mobile device.

7. The method according to claim 1, wherein

when a first information inputted to the vehicle is written in the first space, the second space includes a second information outputted from the vehicle engagement application;

and

when the first information is written in the second space, the first space includes the second information.

8. The method according to claim 7, wherein the first information includes both an input data given by a user via an input device included in at least one of the mobile device and the head unit and an operation data occurring while the vehicle engagement application is executed, and

the second information is mirrored between screens of the head unit and the mobile device.

9. An apparatus for controlling a mobile device engaging a head unit of vehicle, the apparatus comprising:

a controller for executing a vehicle engagement application installed in the mobile device;

a storage including a plurality of buffers, at least one of the buffers containing a frame buffer, the frame buffer including first and second spaces; and

an initialization unit for preparing a predetermined space where the first and second spaces are located in the frame buffer, and for informing the vehicle engagement application of addresses corresponding to the first and second spaces included in the predetermined space,

wherein, after checking whether a first data responsive to an execution of the vehicle engagement application is written in the first and second spaces, the controller performs an autonomous recovery process for the vehicle engagement application when the first data is not written in the first and second spaces.

10. The apparatus according to claim 9, wherein the autonomous recovery process is designed for at least one of:

analyzing an error occurring in the vehicle engagement application;

requesting addition resources when the error is relevant to a lack of resources; and

restarting the vehicle engagement application in response to the error.

11. The apparatus according to claim 9, wherein the controller included in the mobile device assigns a high priority for allocating available resources to the vehicle engagement application.

12. An apparatus for controlling a mobile device engaging a head unit of vehicle, the apparatus comprising:

a controller for executing a vehicle engagement application installed in the mobile device;

a storage including a plurality of buffers, at least one of the buffers containing a frame buffer, the frame buffer including first and second spaces; and

an initialization unit for preparing a predetermined space where the first and second spaces are located in the frame buffer, and for informing the vehicle engagement application of addresses corresponding to the first and second spaces included in the predetermined space,

wherein the controller further;

delivers an event corresponding to a given input into the vehicle engagement application;

checks whether a second data corresponding to the given input is included in at least one of the first and second spaces; and

according to a checking result about the second data, performs an autonomous recovery process for the vehicle engagement application.

13. The apparatus according to claim 12, wherein the autonomous recovery process, after analyzing an error occurring in the vehicle engagement application, performs at least one step of requesting addition resources when the error is relevant to a lack of resources, and restarting the vehicle engagement application in response to the error.

14. The apparatus according to claim 12, further comprising:

an encoder for converting information included in either the first space or the second space, which is changed by the first data, into a predetermined format transferable via a network; and

a communication module for delivering converted information in the encoder into an audio-video-navigation (AVN) device included in the head unit of vehicle.

15. The apparatus according to claim 12, wherein the head unit and the mobile device are coupled via at least one of wired and wireless data communication links so as to exchange at least one of the given input, a video signal, an audio signal and processed data with each other.

16. The apparatus according to claim 12, wherein

when a first information inputted to the vehicle is written in the first space, the second space includes a second information outputted from the vehicle engagement application;

and

when the first information is written in the second space, the first space includes the second information.

17. The apparatus according to claim 16, wherein the first information includes both an input data given by a user via an input device included in at least one of the mobile device and the head unit and an operation data occurring while the vehicle engagement application is executed, and

the second information is mirrored between screens of the head unit and the mobile device.

18. The apparatus according to claim 12, further comprising:

a communication channel for transferring the checking result regarding the second data between an operating system of the mobile device and the vehicle engagement application in real-time.
