An in-vehicle computer is provided with physical resources including a processor having a register and a plurality of physical devices having registers, the in-vehicle computer generates a plurality of virtual devices by allocating the physical resources in a time-sharing manner, and when switching from a first virtual device to a second virtual device, the first virtual device is configured to switch from the first virtual device to the second virtual device, and the second virtual device is configured to switch from the first virtual device to the second virtual device. The register value of the processor related to the first virtual device is stored, the register value of the processor related to the second virtual device is recovered, when the first virtual device is switched to the second virtual device, whether the register value of the physical device used by the second virtual device needs to be changed or not is judged, and when it is judged that the register value needs to be changed, the register value of the physical device used by the second virtual device is changed. The register value of the physical device related to the second virtual device is restored to the physical device.

    车载计算机具备物理资源,所述物理资源包含具有寄存器的处理器及具有寄存器的多个物理设备,所述车载计算机通过以分时方式分配物理资源而生成多个虚拟装置,其中,在从第一虚拟装置向第二虚拟装置切换的情况下,保存与第一虚拟装置有关的处理器的寄存器值,恢复与第二虚拟装置有关的处理器的寄存器值,在从第一虚拟装置向第二虚拟装置切换的情况下,判定第二虚拟装置使用的物理设备的寄存器值是否需要变更,在判定为需要变更的情况下,使与第二虚拟装置有关的物理设备的寄存器值向物理设备恢复。
