To provide a control device to prevent a motor generator from keeping rotating when motor generator electrification control discharges so that charged voltage of a capacitor becomes equal to or less than a specified voltage at the situation in which a relay, that opens and closes an electric route between the capacitor and an inverter, is an open condition.
Command currents idr and iqr set by a command current setting part 30 are converted into components on an αβ coordinate by a fixed coordinate conversion part 50, the sign of a β component is inverted afterwards, and then they are converted into components on a dq coordinate by a rotating coordinate conversion part 54. Through the processes, output of the dq conversion part 54 provides α axis symmetric transformation for the command currents idr and iqr set by the command current setting part 30. For discharge control, feedback control is performed to the symmetrically transformed command currents.
