摘要： 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.

摘要： An object is to provide a driving controller for an AC motor that can prevent generation of an excessive voltage between lines of a motor and between contacts of a motor cut-off contactor and a continuous arc between contacts of the motor cut-off contactor, regardless of the type of a fault occurred, even when a phase in which a current zero point is not generated and a phase in which a current zero point is generated coexist in a fault current that flows between an inverter and the motor. A control unit is configured to open a motor cut-off contactor not at a time when a state of a detected current is determined to be abnormal but at a time when the state of the current is determined to be normal, even when a basic contactor-close command MKC0 becomes off (L level).
