摘要： An in-vehicle system for communicating with an external tool for storing a tool secret key includes: a communication device; a tool key acquisition device; and a communication controller. The in-vehicle system and an external server for storing external tool information provide a vehicular communication system. The external tool information provides a tool public key and key identification information. The tool public key pairs with the tool secret key. When the external tool requests communication connection with the in-vehicle system, the tool key acquisition device transmits the key identification information to the external server, so that the tool key acquisition device acquires the tool public key from the external server. The communication controller performs cryptographic communication with the external tool using the tool public key.

摘要： A vehicular system includes a master ECU, a first slave ECU, and a second slave ECU. The second slave ECU transmits a storing request to the master ECU on detection of a malfunction. The master ECU transmits a storing instruction for causing diagnostic information to be stored, on reception of the storing request. The first slave ECU generates diagnostic information on the first slave ECU, on reception of the storing instruction from the master ECU. The first slave ECU further stores the generated diagnostic information in a retention storage medium. The retention storage medium is configured to retain validity determination information in a condition where the first slave ECU is not supplied with electric power source.

摘要： An in-vehicle system comprising a gateway between multiple networks is disclosed. One of the networks specifies that when a source apparatus connected to the one of the networks sends a request message to a destination apparatus connected to another one of the networks, the source apparatus should time-out if the source apparatus does not receive a response message within a specified time after sending the request message. Upon receipt of the request message, the gateway relays the request message to the destination apparatus and sends a wait request code to the source apparatus to instruct the source apparatus to wait by extending the specified time.

摘要： A bus monitoring security device is connected to a bus, which includes a tool side bus having a tool connection terminal and an ECU side bus. The ECU side bus is coupled with an ECU, and the tool side bus is coupled with a tool capable of communicating with the ECU via the tool connection terminal. The tool side bus and the ECU side bus are separately coupled with the bus monitoring security device. The bus monitoring security device includes: a controller for determining whether the tool being to access the ECU is connected to the ECU side bus, and for restricting transmission and reception of data between the tool and the ECU when the controller determines that the tool is connected to the ECU side bus.

摘要： A diagnostic tool sends a request format designating a virtual address, which is different from a real address for an EEPROM. When a microcomputer determines that an address designated by the received request format is a virtual address assigned to the EEPROM, the microcomputer executes a process, which is designated by the received request format, with respect to the virtual address assigned to the EEPROM.

摘要： A gateway apparatus performs frame forwarding between an external device connected to a first bus and controllers connected to a second bus. Each controller outputs a response frame upon reception of a communication frame from the external device. The response frame has an address field in which a private address is set. The private address is uniquely assigned to each controller in a private network space defined by the second bus. When the communication frame is directed to each controller, the communication frame is forwarded to each controller in sequence at different times to prevent collision between the response frames in the second bus. The private address set in the address field of the response frame is converted into a predetermined transmitting address specified in the first bus.
