Abstract

A vehicle control device includes plural functional modules each of which is a minimum part unit that contributes to change in input/output potentials, and has an input and an output of one power line or one set of power lines, except for power lines having a same potential as that on an overhead wire side or that on a ground side. The functional module has an interface surface on one side surface, to which both of a signal line and the power line are connected. Each interface surface is divided into a first interface area in which a signal line terminal connected to the signal line is placed, and a second interface area in which a power line terminal connected to the power line is placed. The plural functional modules are adjacently arranged such that the interface surfaces face in a same direction, the first interface areas are located on one end side in common, and the second interface areas are located on the other end side in common.
