The start sensing means senses based on the data, which is received via the receiving means, that the control device compatible with the partial network changes from the sleep state to a start state. The memory means stores state specific information, which is information making it possible to specify whether the control device compatible with the partial network stays in the sleep state at an arbitrary time point, on the basis of the results of sensing by the sleep sensing means and start sensing means.

摘要： PROBLEM TO BE SOLVED: To provide a relay device that can prevent unauthorized reprogramming of an ECU.SOLUTION: A G/W-ECU is connected with an ECU via an in-vehicle LAN and also connected with an external tool via another communication path other than the in-vehicle LAN, and relays transmission and reception of frames between the ECU and the external tool. In addition, the G/W-ECU is in a state in which reprogramming of the ECU by the external tool is prohibited, but if operation in accordance with an authentication procedure is performed to an operation part of its own vehicle, it permits relaying a reprogramming frame. Further, if operation in accordance with the authentication procedure is performed, a frame to be relayed is not limited to a reprogramming frame. In addition, a frame to be relayed is registered in advance, and if operation in accordance with the authentication procedure is performed, it permits relaying a reprogramming frame according to this. Some frames (basic relay frames) may be relayed regardless of presence or absence of the authentication procedure.

摘要： PROBLEM TO BE SOLVED: To provide a technology capable of quickly returning to receiving processing even if a receiving controller detects a receiving error by preventing the transmission/reception of an ACK slot from being performed between controllers in an own device. SOLUTION: A received signal supplied from a receiver 62 of a transceiver 60 and a control signal outputted from a transmitting terminal Tx of a CAN controller 34 are inputted to a receiving terminal Rx of the CAN controller 34 at the sub-control microcomputer 30 side by being synthesized by an AND gate 70 so that a low level of the respective signals becomes a preferential level. On the other hand, the received signal supplied from the receiver 62 of the transceiver 60 is directly inputted to the receiving terminal Rx of the CAN controller 24 at the main control microcomputer 20 side. Thus, when the ACK slot and an error plug (signal of low level) are outputted from the transmitting terminal Tx of the CAN controller 34, these signals are preferentially inputted to the receiving terminal RX of the CAN controller 34.
