System and method applicable to automotive vehicles utilizing time division multiplex mode for communicating data between master and slave stations
First Claim
1. A time division multiplex communication system, comprising:
- a) a master station for sequentially accessing a plurality of slave stations according to a predetermined calling order within a predetermined period of time and for transmitting a required information to any of the slave stations on the basis of information received from one accessed slave station;
b) a transmission line connected between the master station and the plurality of slave stations for transmitting the information between the master station and slave stations; and
c) changing means, responsive to the information received from the one accessed slave station, for changing the predetermined calling order according to the information received by the master station from the one accessed slave station so as to enhance a characteristic of the system for responding to the information from the one accessed slave station,wherein the changing means comprises first means for increasing the access frequency of a particular slave station and at least one other corresponding slave station which carries out an operation in response to the information from the master station.

Abstract
A time division multiplex communication system applicable to an automotive vehicle and a method for communicating data between a master station and a plurality of slave stations are disclosed in which a master station is provided for sequentially accessing a plurality of slave stations according to a predetermined calling order within a predetermined period of time and for transmitting a required information to any of the slave stations on the basis of information received from one accessed slave station. A transmission line is connected between the master station and the plurality of the slave stations, and the master station is provided with a logic portion which, responsive to the information from the one accessed slave station, is active for changing the predetermined calling order in a subsequent cycle of the predetermined period of time according to the information received by the master station from the one accessed slave station so as to enhance a characteristic of the system for suitably responding to the information from the one accessed slave station.

13. A time division multiplex communication system, comprising:
-
a) a master station for sequentially accessing a plurality of slave stations according to a predetermined calling order within a predetermined period of time and for transmitting a required information to any of the slave stations on the basis of information received from one accessed slave station; b) a transmission line connected between the master station and the plurality of slave stations for transmitting the information between the master station and slave stations; and c) changing means, responsive to the information received from the one accessed slave station, for changing the predetermined calling order according to the information received by the master station from the one accessed slave station so as to enhance a characteristic of the system for responding to the information from the one accessed slave station, wherein; the changing means comprises first means for changing the calling order so as to access, in sequential proximity to the one accessed slave station, a slave station which requires an operation in response to information received by the master station from the one accessed slave station; and the slave stations include a plurality of operation units having operations portions and a plurality of terminal units each having one or more terminals corresponding to respective operation units, and wherein the first means includes; second means for collecting operation information related to operation of each operation unit with each operation unit being sequentially called; third means for changing the calling order to sequentially call terminal unit according to the collected operation information; and fourth means for driving the terminals corresponding to the operation unit according to the collected information when each terminal unit is called according to the changed calling order.
