Abstract
A vehicle device in one embodiment includes: a control unit in which a system is built, a plurality of operating systems operating on the system; and a plurality of monitoring units that are configured to monitor a defect in the system. Each of the plurality of monitoring units is further configured to: perform monitoring at a respective one of a plurality of layers into which the system are divided; and solve a defect at the respective one of the plurality of layers when the defect occurs.
Claims6
A vehicle device, comprising:
- a control unit in which a system is built, a plurality of operating systems operating on the system;
- and
- a plurality of monitoring units that are configured to monitor a defect in the system, wherein
- each of the plurality of monitoring units is further configured to:
- perform monitoring at a respective one of a plurality of layers into which the system is divided;
- and
- solve a defect at the respective one of the plurality of layers when the defect occurs, wherein
- the plurality of monitoring units include a first monitoring unit that is configured to perform monitoring at a first layer outside of the control unit where the control unit is a monitoring target, a second monitoring unit that is configured to perform monitoring at a second layer in the system in the control unit where the plurality of operating systems are a monitoring target, and a third monitoring unit that is configured to perform monitoring at a third layer in the system on the plurality of operating systems where application programs are a monitoring target,
- the first monitoring unit is configured to solve a defect by restarting the entire control unit when the defect occurs in the control unit,
- the second monitoring unit is configured to, when a defect occurs in one of the plurality of operating systems, solve the defect by restarting the one of the plurality of operating systems, and
- the third monitoring unit is configured to, when a defect occurs in one of the application programs, solve the defect by restarting the one of the application programs.
