Abstract
In an on-vehicle terminal system operating a plurality of operating systems, control of peripheral devices connected to the on-vehicle terminal system can be continued even if one of the operating systems is stopped. A second operating system monitors an operating status of a first operating system using an OS status monitoring function. When the first operating system stops, a list recording allocation of the peripheral devices is updated to switch the allocation to the second operating system. By doing so, an interrupt signal from a peripheral device is allocated to the second operating system, and accordingly the second operating system can control the peripheral device.
