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.

Abstract: An anomaly handling method using a device installed outside of a vehicle is disclosed. The method includes receiving, from the vehicle, an anomaly detection notification, which includes level information indicating a level affecting safety, and a location of the vehicle. The method also includes obtaining a location of another vehicle and determining whether a distance between the location of the vehicle and the location of the other vehicle is within a predetermined range. When the distance is within the predetermined range and is shorter than a first predetermined distance, not changing the level information and transmitting the received anomaly detection information to the other vehicle. When the distance is within the predetermined range and is longer than or equal to the first predetermined distance, changing to decrement a level indicated by the level information, and transmitting changed anomaly detection information to the other vehicle.

Abstract: An anomaly detection electronic controller performs anomaly detection processing and is connected to a network, which a plurality of electronic controllers uses for communication. The anomaly detection electronic controller includes an anomaly detection processor that performs anomaly detection processing regarding a data frame. The anomaly detection controller also includes an anomaly detection processing requester that decides an anomaly detection processing timing when receiving the data frame, the anomaly detection processing timing being a reception timing of one or multiple fields in the data frame. The anomaly detection processor further performs the anomaly detection processing regarding the data frame at the anomaly detection processing timing decided by the anomaly detection processing requester.

Abstract: An anomaly handling method using a roadside device is disclosed. The method includes receiving, from a vehicle, an anomaly detection notification, which includes level information indicating a level affecting safety, and a location of the vehicle. The method also includes obtaining a location of the roadside device and determining whether a distance between the location of the vehicle and the location of the roadside device is within a predetermined range. When the distance is within the predetermined range and is shorter than a first predetermined distance, not changing the level information and transmitting the received anomaly detection notification externally from the one vehicle. When the distance is within the predetermined range and is longer than or equal to the first predetermined distance, changing to decrement a level indicated by the level information, and transmitting changed anomaly detection notification externally from the one vehicle.

Abstract: An update management method is used in an onboard network system having a plurality of electronic control units (ECUs) that performs communication via a network and connects to an external tool. The method includes a master ECU storing a shared key and an expiration date of the shared key. When the master ECU receives an update message, verifying update authority information indicating authority of the external tool, and determining whether or not a transmission of the update message is within a range of an authority of the external tool. The method also includes acquiring external point-in-time information, determining whether or not the external point-in-time information is before the expiration date, and transmitting an alert message prompting an update of the shared key. The ECUs are prioritized according to a designated level of authority, including chassis-related functions, body-related functions, safety/comfort functions, and telematics/infotainment functions.
