In a data cooperation system in which information cooperates in a first system, a second system and a third system, the first system provides an already operating service and collects and publicizes behavior data as information for providing the service, the second system acquires the behavior data, generates a verification result applying the behavior data to a new technology as verification data, and publicizes the verification data, and the third system receives the behavior data and the verification data, supports decision of the determination result data, and publicizes the decided determination result data.

Data cooperation system, data cooperation method, trust system, and data publicizing method

A routing method and an in-vehicle gateway device having a plurality of interfaces for communication, automatic setting of routing function is enabled to perform, in consideration of characteristics of data which a connecting network handles. A network is classified to an information-system, a control-system and a safety-system, based on characteristics thereof, and which one of the systems includes a network connecting to the in-vehicle gateway device, is judged from equipments connecting to the network, or traffic of the network. Still more processing in data exchange among different classifications is set in advance.

Routing method in in-vehicle gateway device

An on-vehicle gateway device connected to an information system network and a control system network of a vehicle executes monitoring the status of an information system via an information system access circuit taking charge of message transmission and reception to and from the information system network, and an information system management step to manage information acquired by the information system monitoring, monitoring the status of a control system via a control system access circuit taking charge of message transmission and reception to and from the control system network, and a control system management step to manage information acquired by the control system monitoring, managing policies for access control by the access control circuit controlling data flows between the information system access circuit and the control system access circuit, and determining whether or not to update the policies managed by policy management and to update the policies.

On-vehicle gateway device, method for controlling an on-vehicle gateway device, connection device and connection control method

A diagnostic equipment coupled to a vehicle network makes an inquiry about internal information, e.g., yes or no whether there is a logging-available memory area, with respect to each of a plurality of ECUs, and only to any of the ECUs making a response of yes, e.g., having such a memory area, a notification is made when some defect is observed. The internal information is then gathered from the ECU, and in response to an inquiry about the internal information coming from the diagnostic equipment, the ECU forwards back information about yes or no for logging thereto. When the ECU is available for logging, log data that has been periodically accumulated is forwarded back as a response with respect to a retrieval request therefor from the diagnostic equipment.

Vehicle-mounted information system, and data gathering method in diagnostic equipment

In a navigation system integrated with a diagnostic device, an arithmetic and control unit for diagnostic communication makes an inquiry to electronic control units, such as an engine control unit, a transmission control unit and a brake control unit connected a CAN, about data which is used for the diagnosis of trouble causes based on setting information stored in a memory through diagnostic communication. An arithmetic and control unit for navigation system receives messages responding to the inquiry to sift through the data to be collected based on the setting information in the memory and stores the collected information in a hard disk drive device. The setting information is updated by making an inquiry to an external center via a mobile communication network.
