Abstract
An on-board device includes: a control unit in which a plurality of virtual devices serve as an operation environment for programs; and a storage unit that stores a virtualization operating system. Each of the virtual devices: includes a communication buffer to which an area from the storage unit is assigned; and writes the communication data addressed to another virtual device, to the virtual device's own communication buffer when communicating with the other virtual device, a management unit that manages the virtual devices: reads out the communication data written to the communication buffer; writes the communication data to a storage area that is accessible to the management unit; and writes the communication data written to the storage area to the communication buffer of the other virtual device. The other virtual device reads out the communication data transmitted from the virtual device, written to the other virtual device's own communication buffer.
