A vehicle-mounted communication device (“VMCD”) transmits a device ID identifying the VMCD to a TA, acquires a terminal ID from the TA, and transmits the device ID and the terminal ID acquired from the TA to a central apparatus. The TA transmits a terminal ID identifying the TA to the VMCD, acquires a device ID from the VMCD, and transmits the terminal ID and the device ID acquired from the VMCD to the central apparatus. The central apparatus receives a device ID and a terminal ID transmitted from the VMCD and a device ID and a terminal ID transmitted from the TA, and compares the device ID and the terminal ID received from the VMCD with the device ID and the terminal ID received from the TA.

Abstract: Provided are a communication system and a communication device that allow a reception node to estimate delay time, a generation time point or the like of a message. A delay time estimation part in an ECU determines whether a message received by itself is transmitted in sequence with another message without being provided with time information by a transmission node. If the received message is transmitted in sequence with another message, the received message may be delayed due to arbitrary processing. Thus, the delay time estimation part checks the priority of one or more sequential messages preceding the received message, and estimates delay time of the received message occurring due to the arbitrary processing in accordance with the priority of each message. A generation time point estimation part estimates the time point when the received message is generated by an ECU, based on the delay time estimated.

Abstract: Provided are a CAN communication system and an error information recording device that may be expected to facilitate identification of the cause of any error occurring in communication. The monitoring device is connected to a CAN bus and determines whether or not an error is included in a message transmitted by an ECU. In the case where an error is included in the transmitted message, the monitoring device records, in the recording unit, information concerning the error in the message as error information. Furthermore, the monitoring device comprises the CAN controller performing communication in accordance with the CAN protocol and the processor performing various types of information processing. The CAN controller may determine whether or not an error is included in message transmission, and if determined that an error is included, may notify the processor of the CAN-ID attached to the message by an interrupt.

Abstract: Provided are a communication control device and a communication system capable of detecting message transmission in the case where an invalid device transmits a message to a common communication line. A monitoring device decides a reference time point t0 for periodical message transmission by an ECU, decides multiple scheduled transmission time points t1, t2, . . . obtained by adding a period corresponding to an integer multiple of a transmission cycle T of a message to the reference time point t0, and decides that a predetermined period including each of the scheduled transmission time points is a permission period for message transmission. The monitoring device determines whether or not a detected message on a CAN bus has been transmitted during the permission period. If determined that transmission of an invalid message is not permitted, the monitoring device performs processing of causing the ECU which receives the message to discard the message.
