Patent ID: 8701809

Claim:
A vehicle control device comprising: a plurality of functional modules each of which has only one part that makes an output potential different from an input potential due to an operation thereof and, from the one part, a module providing an output potential equal to an input potential is not capable of being separated; and signal lines and power lines connected to the plurality of functional modules, wherein each of the functional modules has an interface surface on one side surface thereof, to which both of the signal line and the power line are connected, each of the interface surfaces 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, and the plurality of functional modules are adjacently arranged such that the interface surfaces face in a same direction, the first interface areas are located on one side in common, and the second interface areas are located on the other side in common.
