<p>The present invention relates to a CAN communication system CAN-communicating through a bus line shared by groups, CAN-communicating with electronic devices included in another group by connecting bus lines to each other when necessary, linked-operating a plurality of bus lines improving the stability of a signal by leaving only two terminal resistances when connecting bus lines to each other. For this reason, the present invention divides the electronic devices into a plurality of groups, has a bus line connected to terminate the resistances on both ends in each group, makes electronic devices included in a group CAN-communicate with each other, connects electrically the bus lines to each other, has integral bus lines, has a relay which electrically separates from the bus lines other terminating resistances except for the two connected to the integral bus lines, and can select only one of the performing CAN-communicating between the electronic devices of the same group and perform CAN-communicating between the electronic devices of the same groups or other groups.</p> |
