Document Type and Number:
WIPO Patent Application WO/2023/140093
Kind Code:
A1
Abstract:
This on-vehicle control device is mounted on a vehicle and comprises: physical resources including a control unit, a storage unit, and a communication unit; and a management unit that generates a plurality of virtual machines by allocating the physical resources for each allocated time. The plurality of virtual machines include: a first virtual machine that communicates with an external device installed outside the on-vehicle control device, and executes processing which cannot be carried over to the next cycle; and a second virtual machine that executes processing which can be carried over to the next cycle. The management unit executes a first modification control that modifies each allocated time for the first virtual machine and the second virtual machine. The first modification control includes: a control that acquires a processing time for the first virtual machine in a first cycle; and a control that, if a margin time calculated on the basis of the acquired processing time and the allocated time set for the first virtual machine, or the rate of change of the margin time is less than a first predetermined value, extends the allocated time for the first virtual machine and shortens the allocated time for the second virtual machine in a cycle after the first cycle.
