PROBLEM TO BE SOLVED: To provide a system which can detect disconnection and in which a plurality of control systems can independently or simultaneously detect discon nection even in the case of the partial disconnection of an inter-bus for forming multiple system or the partial falling of the connection parts of the bus. SOLUTION: In this multiplexed control system connecting an A system control system 1 and a B system control system which are parallelly connected by the inter-system bus 3, signal lines 3a and 3b for disconnection detection are arranged between connection parts 4 and 5, disconnection detection circuits 7 and 9 that simultaneously detect the disconnection of each of the lines 3a and 3b are provided, data are also received through the bus 3, disconnection detection functioning parts 17 and 8 using software checking the soundness of the data are provided. |
