Vehicular control apparatus
A vehicular control apparatus is used in an onboard system provided with a plurality of information processors mutually connected via a communication bus, and includes a storage section for storing information, and an arithmetic section for executing a process based on the information stored in the storage section. The information contains first management information relating to a security abnormality as a communication data abnormality owing to security attack from outside the onboard system, and second management information relating to a safety abnormality as a communication data abnormality owing to an abnormality in the onboard system. The first management information contains first limit condition information indicating a first limit condition for executing a security coping with the security abnormality. The second management information contains second limit condition information indicating a second limit condition for executing a safety coping with the safety abnormality. Upon detection of the communication data abnormality in the onboard system, the arithmetic section determines a coping content to the detected communication data abnormality based on the first management information and the second management information.
Monolithic high-voltage transceiver connected to two different supply voltage domains
A transceiver has a first interface supplied by a first supply voltage to interface with external devices operating in a first supply domain and a second interface supplied by a second supply voltage and adapted to interface to an external communication bus operating in a second supply domain. The transceiver has a first internal communication link, which is adapted to transfer transmit data generated by an external device operating in the first supply domain, from the first interface to the second interface, and a second internal communication link, which is adapted to transfer transmit data be supplied from the external communication bus operating in the second supply domain from the second interface to the first interface.
RELAY DEVICE, IN-VEHICLE COMMUNICATION SYSTEM, VEHICLE, AND IN-VEHICLE COMMUNICATION METHOD
Provided is a relay device including: a relay unit configured to perform a relay process for a frame transmitted and received between a plurality of function units; and a relay management unit. The relay unit receives, from a function unit, a target frame. When a content of the target frame satisfies a predetermined condition, the relay management unit stores, in the target frame, position information which is information regarding a position, in the in-vehicle network, of a function unit as a request source of a service related to the target frame or a function unit as a request destination of the service related to the target frame, and outputs the target frame having the position information stored therein, to the relay unit. The relay unit transmits the target frame received from the relay management unit, to a function unit which is a destination of the target frame.
RELAY DEVICE, IN-VEHICLE COMMUNICATION SYSTEM, VEHICLE, AND IN-VEHICLE COMMUNICATION METHOD
Provided is a relay device including: a relay unit configured to perform a relay process for a frame transmitted and received between a plurality of function units; and a relay management unit. The relay unit receives, from a function unit, a target frame which is transmitted and received according to a predetermined communication protocol and includes information with which a request source of a service is identifiable and information with which a content of the requested service is identifiable, and the relay unit outputs the received target frame to the relay management unit. The relay management unit performs determination regarding setting change in the relay process of the relay unit, on the basis of the information included in the target frame received from the relay unit, and outputs the target frame to the relay unit or discards the target frame, according to a result of the determination.
ONBOARD ECU, PROGRAM, AND INFORMATION PROCESSING METHOD
An onboard ECU communicatively connected to an onboard apparatus installed in a vehicle and a vehicle control apparatus that executes processing relating to driving an onboard apparatus includes a control unit that executes processing relating to control of the onboard apparatus, wherein the control unit acquires an input signal relating to control of the onboard apparatus, derives a count value on the basis of changes in the acquired input signal, outputs a first signal for transitioning the vehicle control apparatus to an activated state in a case where the derived count value reaches a first threshold, and outputs a second signal for requesting the onboard apparatus to be driven in a case where the derived count value reaches a second threshold; and the second threshold is a value greater than the first threshold.
ONBOARD DEVICE AND SLEEP CONTROL METHOD
An onboard device includes: a communication unit configured to communicate with an onboard device included in an onboard network; a detection unit configured to detect a new onboard device that is an onboard device newly added to the onboard network; and a sleep processing unit configured to, in a detected state where the new onboard device has been detected by the detection unit, transmit a sleep request for transitioning to a sleep state in synchronization with an onboard device included in the onboard network, to the new onboard device via the communication unit.
Device for processing data including at least two data interfaces, and operating method therefor
