Document Type and Number:
Japanese Patent JP6861013
Kind Code:
B2
Abstract:
The present invention provides an electronic controller and the like capable of identifying the order of communication apparatuses connected to a bus while minimizing manufacturing cost. In the present invention, bus wiring 2 has one end connected to a port 111 and the other end connected to a port 112. A plurality of lower ECUs 301 to 304 are connected to the bus wiring 2. A current sensor CS measures current Is1 flowing through the port 111 and current Is2 flowing through the port 112 by applying current to the bus wiring 2 from each of the plurality of lower ECUs 301 to 304. The higher controller 12 identifies the order of the plurality of lower ECUs 301 to 304 on the bus wiring 2 on the basis of the current Is1 and the current Is2 which are measured for each of the plurality of lower ECUs 301 to 304.
