Abstract
It is determined whether or not an automatic transmission is in a pre-gear shift state determined in advance prior to a power-ON gear shift in which torque-down control is performed. When the automatic transmission is in the pre-gear shift state, since a required free capacity is secured in a capacitor, torque-down control of a second motor generator is performed in a gear shift, and even if surplus power is generated in a power supply circuit due to the torque-down control, the surplus power can be quickly absorbed using the capacitor. Since a required free capacity is secured in the capacitor by determining whether or not the automatic transmission is in the pre-gear shift state, a predetermined free capacity does not need to be secured constantly, normal capacitor storage control focusing on drivability or the like can be performed normally, and use restriction of the capacitor is minimized.
