Title:
ELECTRIC CONTROL UNIT AND ELECTRIC CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/193845
Kind Code:
A1
Abstract:
Provided is an electric control device (10, 20, 30) having a plurality of virtual machines managed by a hypervisor (300) comprising: a monitoring unit (201) that detects abnormality occurred in one virtual machine (100) of the plurality of virtual machines and outputs a stop request for requesting to stop allocation of CPU resources to the one virtual machine when abnormality has been detected, the monitoring unit being provided on the other virtual machine (200) different from the one virtual machine; an allocation control unit 301 provided in the hypervisor for stopping allocation of the CPU resources to the one virtual machine on the basis of the stop request; a shared memory (401); and a DMA controller (402) that performs DMA (Direct Memory Access) transfer to the shared memory of data transmitted to the one virtual machine to which allocation of the CPU resources has been stopped.
