Vehicle device
A vehicle device includes a control unit and a monitoring unit monitoring an abnormality occurred in the control unit and solving the abnormality. The control unit includes a plurality of operating systems that respectively control a plurality of human machine interfaces. The monitoring unit monitors whether the abnormality is occurred in functions of the control unit. In response to a detection of the abnormality, the monitoring unit solves the abnormality of the function in which the abnormality is detected while continuing operation of the function in which the abnormality is not detected.
1. A vehicle device comprising:
a control unit;
a monitoring unit monitoring an abnormality occurred in the control unit and solving the abnormality; and
a substitute unit that substitutes at least a part of control executed by functions of the control unit,
wherein
the control unit includes a plurality of operating systems that respectively control a plurality of human machine interfaces,
the control unit provides the functions in software manner by executing programs with the plurality of operating systems,
among the functions installed in the plurality of operating systems, the monitoring unit monitors whether the abnormality is occurred in a display function related to the plurality of human machine interfaces,
in response to a detection of the abnormality of the display function, the monitoring unit solves the abnormality of the display function,
during the abnormality being solved, the monitoring unit controls the substitute unit to execute at least a part of the display function in which the abnormality is detected or notify that the abnormality is being solved by displaying information on one of the plurality of human machine interfaces.
2. The vehicle device according to claim 1 , wherein
the plurality of operating systems include a first operating system and a second operating system,
the first operating system mainly processes information related to a vehicle and has a higher stability relative to the second operating system,
the second operating system mainly processes multimedia information and has a lower stability relative to the first operating system, and
the control unit assigns the functions of the control unit to the first operating system and the second operating system.
3. The vehicle device according to claim 2 , wherein
the monitoring unit is included in the first operating system and detects the abnormality occurred in the second operating system.
4. The vehicle device according to claim 1 , wherein
the monitoring unit is included in one of the plurality of operating systems which has a highest stability relative to remaining operating systems, and
the monitoring unit detects the abnormality occurred in another one of the plurality of operating systems.
5. The vehicle device according to claim 1 , wherein
the monitoring unit is included in each of the plurality of operating systems, and
each monitoring unit detects the abnormality occurred in another operating system.
6. The vehicle device according to claim 1 , wherein
the control unit controls the human machine interface that displays information on a display device.
7. The vehicle device according to claim 1 , wherein
the control unit controls the human machine interface that displays images captured by a camera on a display device.
8. The vehicle device according to claim 1 , wherein
the control unit includes three or more operating systems as the plurality of operating systems.
9. A vehicle device comprising:
a microcomputer including a first operating system and a second operating system, each of the first operating system and the second operating system controls a corresponding human machine interface; and
a storage storing application programs to be executed by the microcomputer,
wherein
the first operating system mainly processes information related to a vehicle and has a higher stability relative to the second operating system,
the second operating system mainly processes multimedia information and has a lower stability relative to the first operating system,
the microcomputer provides, in software manner by executing the application programs stored in the storage, a first function and a second function with the first operating system and the second operating system, respectively,
the microcomputer, by executing a substitute application in software manner, substitutes at least a part of control executed by the first function and the second function of the microcomputer,
the first operating system includes a monitoring application that monitors an abnormality occurred in the second function executed by the second operating system, the second function is a display function related to the human machine interface,
in response to a detection of the abnormality in the display function, the microcomputer solves the abnormality of the display function while continuing operation of the first function in which the abnormality is not detected, and
during the abnormality of the display function being solved, the microcomputer, by executing the substitute application, executes at least a part of the display function in which the abnormality is detected or notify that the abnormality of the display function is being solved by displaying information on the human machine interface.
