<p>An automobile multiplex data communication system includes: a plurality of child stations; a parent station for controlling a multiplex data communication established with the plurality of child stations; and a signal transmission path for mutually connecting the parent station with said plurality of child stations. The parent station is arranged by a storage unit for storing data about a condition-stabilizing time period specific to the operation member, defined by a time duration after the operation member has been manipulated until an operation condition becomes a stable condition; a first operation-condition detecting unit for detecting at least two successive operation conditions of the operation member connected to the communication unit of each child station to produce first and second operation-condition detection data; a condition-change detecting unit for detecting a change in at least the two successive operation conditions of the operation member; a second operation-condition detecting unit for detecting another operation conditions of said operation member after the operation condition change has been detected by the operation-change detecting unit and when the operation-stabilizing time period specific to the operation member has elapsed, thereby producing third operation-condition detection data free from an adverse influence caused by a chattering phenomenon of the operation member; a setting unit for setting a drive instruction of the terminal unit based upon the third operation-condition detection data; and a transmission unit for transmitting the drive instruction to the child station with the operation member whose operation condition has been detected as the third-condition detection data.</p> |
