Claim 0:
1. 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.
