Abstract: A master control device is communicatively coupled to a first slave control device and a second slave control device via a first network and a second network, respectively. The master control device provides output data to the first slave control device based on input data received from the second slave control device. A monitoring apparatus which monitors an operation of the master control device stores determination data indicating a correspondence relationship between the input data and the output data, obtains the input data provided to the second network by the second slave control device and the output data provided to the first slave control device via the first network, and determines a presence or an absence of an anomaly in the operation of the master control device by determining whether the input data and the output data correspond to the determination data.

Abstract: An ECU (Electronic Control Unit) includes a HV (HyperVisor), and a first VM (Virtual Machine) and a second VM that operate on the HV. The first VM detects an abnormality in a process in the first VM. When the first VM detects an abnormality, the first VM notifies the second VM of information related to the abnormality via the HV. The second VM executes a process responsive to the abnormality, based on the information related to the abnormality provided from the first VM.

Abstract: An integrated ECU is a vehicle control system provided in a vehicle, and includes: an application executor that executes an application program; an environment state determiner that determines whether the application executor is anomalous; a first resource provider that provides a resource to be used for controlling the vehicle; and a first access controller that, upon acceptance of a request for the resource from the application program, (a) prohibits provision of the resource from the resource provider to the application program, when the environment state determiner determines that the application executor is anomalous, and (b) permits the provision of the resource from the resource provider to the application program, when the environment state determiner determines that the application executor is not anomalous.

Abstract: An electronic control apparatus includes: an obtaining unit configured to obtain data transmitted via a network in a system; and a judging unit configured to judge presence or absence of an anomaly in the data obtained by the obtaining unit, based on a transmission state of the data. The judging unit is configured to judge that an anomaly is present in the data, when the transmission state of the data is a transmission stopped state.
