  • Patent number: 11936500
    Abstract: An in-vehicle network system deployed in a vehicle includes a plurality of first nodes configured to perform an operation relevant to a first function in the vehicle, a second node configured to perform an operation relevant to a second function different from the first function in the vehicle; and a relay device configured to relay communication between the first nodes and the second node. The relay device is configured to start relay of communication between the first nodes earlier than the relay of communication between the first node and the second node at a time of startup.

  • Patent number: 8489932
    Abstract: There is provided a server system that collects memory information at the time of occurrence of a failure if a failure occurs in the operating system so as to enable failure analysis. Stall monitoring of a firmware is performed by hardware and, if a stall is detected, a reset is performed. A memory has a memory area used by a boot loader of the firmware and a memory area used by another part of the firmware. It is determined based on a reset factor retained in a device whether the reset is a normal reset or a reset associated with the stall detection. In the case where the reset is a reset associated with the stall detection, information of the memory area of the memory used by the another part of the firmware at the time of occurrence of the stall is collected.
