<P>PROBLEM TO BE SOLVED: To provide a redundant data bus system capable of quickly identifying a failure position. <P>SOLUTION: The redundant data bus system comprises: a first transmission path where data is transmitted/received between a controller and a first microcomputer through a first driver; and a second transmission path where data is transmitted/received between the controller and the first microcomputer through a second driver. The controller transmits an operation check signal to the first microcomputer through the first and second transmission paths and receives a reply signal from the first microcomputer through the first and second transmission paths. <P>COPYRIGHT: (C)2012,JPO&INPIT |
