Abstract
This motor control apparatus is provided with: a reduced energy calculation device that calculates a reduced energy that is produced when a drive mode of a hybrid vehicle is shifted from a drive mode driven by a motor to a drive mode driven by an internal combustion engine and if the phase of the motor is changed from the present phase to the arbitrary required phase; a displacement energy calculation device that calculates a displacement energy that is produced when the present phase is changed to the arbitrary required phase; and a phase change permission device that compares the reduced energy and the displacement energy, and permits changing from the present phase to the required phase when it is determined that the reduced energy is greater than the displacement energy.
