<p><P>PROBLEM TO BE SOLVED: To provide a vehicular control system capable of suitably recording missing node so as to facilitate break-through of cause of failure. <P>SOLUTION: In the vehicular control system, a plurality of control units are connected through an in-vehicle network 20, and when abnormality of power source voltage is generated on themselves, the control units 100-500 connected to the in-vehicle network 20 feed out the matter to the in-vehicle network 20 with unit specifying information for specifying itself and shut off the connection with the in-vehicle network 20. Another control unit 100-500 makes the node of the control unit as the missing node and does not record it when the matter of the abnormality of the power source voltage is informed from the control unit in which communication is stopped. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
