Abstract

A motor charge-discharge torque limit correction coefficient for during cylinder deactivation enlargement assistance, which changes with an increasing trend according to an increase in a regeneration/assistance integrated residual amount which is an integrated value of the energy amount obtained during deceleration regeneration of vehicle, that is a correction coefficient which corrects to decrease an energy management discharge torque limit which is an upper limit value of motor torque set according to for example, an energy state in high voltage electrical equipment and an operating state of the vehicle, when assisting the output from the internal-combustion engine by the motor, is calculated. A value obtained by correcting the energy management discharge torque limit is set to an energy management discharge torque limit for cylinder deactivation enlargement assistance, and a cylinder deactivation upper limit ENG torque is added so as to calculate a cylinder deactivation upper limit torque.
