  • Publication number: 20230153099
    Abstract: A gateway device is connected via network(s) to electronic controllers on-board a vehicle, where at least one of the electronic controllers is implemented in a virtual machine. The gateway device includes one or more memories, and circuitry that acquires firmware update information. The circuitry determines whether a first electronic controller satisfies a second condition based on second information, which is whether the first electronic controller includes a firmware cache for performing a pre-update firmware cache operation. The circuitry also causes, when the second condition is not satisfied, the gateway device to execute a proxy process, where the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, creates updated boot ROM data with the updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM and resets the first electronic controller with the updated firmware.

  • Publication number: 20220116405
    Abstract: An electronic control unit is connected to a network in an in-vehicle network system. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the network via the second control circuit. The second control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. Upon determining that the frame conforms to the first rule, the second control circuit transmits the frame to the first control circuit. The first control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule. The second rule is different from the first rule.
