Abstract: A gateway device is connected to a plurality of electronic controllers on-board a vehicle. The gateway device acquires firmware update information, which includes at least a part of updated firmware to be applied to a first electronic controller, patch data, and information indicating where to apply the patch data. When the gateway device determines that the first electronic controller does not include a firmware cache for performing a pre-update firmware cache operation, the gateway device executes a proxy process. In this regard, the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, merges the patch data and existing firmware to create updated boot ROM data with updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM data and resets the first electronic controller with the updated firmware.

Abstract: A vehicle log transmission device includes: an anomaly detector that obtains a vehicle log from at least one electronic control unit, detects an anomaly based on log information in the vehicle log, and extracts log information in which the anomaly is detected as an anomaly log; an anomaly notifier that transmits the anomaly log to a server; a change instructor that, based on a vehicle state extracted from the vehicle log, transmits, to the at least one electronic control unit, a change instruction to change a save priority level of the log information included in the vehicle log; and a vehicle log request responder that, when a vehicle log request is received, obtains the vehicle log including log information saved based on the save priority level changed in response to the change instruction, and transmits the vehicle log obtained to the server.

Abstract: An anomaly detection server is provided. The anomaly detection server is a server for counteracting an anomalous frame transmitted on an on-board network of a single vehicle. The anomaly detection server acquires information about multiple frames received on one or multiple on-board networks of one or multiple vehicles, including the single vehicle. The anomaly detection server, acting as an assessment unit that, based on the information about the multiple frames and information about a frame received on the on-board network of the single vehicle after the acquisition of the information about the multiple frames, assesses an anomaly level of the frame received on the on-board network of the single vehicle.

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.

Abstract: A vehicle monitoring apparatus includes: a first communicator that receives specifying information for specifying a target vehicle from a server; and an acquirer that acquires driving information from the target vehicle, the driving information being information regarding driving of the target vehicle specified by the specifying information received by the first communicator. The first communicator transmits the driving information acquired by the acquirer to the server. For example, the acquirer may acquire the driving information obtained from the target vehicle through communication.

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.
