  • Patent number: 11136044
    Abstract: A vehicle control device capable of improving safety, even when abnormality in the operation of an arithmetic processing unit occurs. A second microcomputer receives trajectory information transmitted from a first microcomputer via a communication line and calculates control commands to actuators to synchronize the arithmetic processing unit allowing the first and second microcomputers to be synchronized. The second microcomputer performs a calculation and compares the result with the calculation result of the first microcomputer so that the second microcomputer can accurately determine whether or not the first microcomputer is abnormal. When the abnormality occurs in the first microcomputer based on the determination, the actuators are controlled by switching to the control commands calculated by the second microcomputer which is synchronized with the arithmetic processing unit. Thus, the device performs seamless self-driving control without the occurrence of abrupt control gaps.

An edge node DCE-1 of a data center 40-1 and edge nodes TPE-1, TPE-2 of a transport network are connected to each other by a link TPE-1-1 and a link TPE-2-1, respectively. The edge nodes TPE-3 and TPE-1, TPE-2 that hold a node AE51 of a user site 50 are set with an LSP 110 of an active system, and an LSP 120 of a backup system, respectively. One of the links is active, and the other link is backup, and the LSP of the TPE node having the active link in the LSP 100 and the LSP 120 is made active. The respective links are prioritized, and the links are switched to an active state in order from the links higher in the order of priority when a link failure or an LSP failure occurs.
