In the process of cranking and starting an engine by a motor, until a predetermined condition is satisfied, i.e., until a rotation speed Ne of the engine is equal to or higher than a predetermined rotation speed Nstmg and a crank angle cr of the engine is in a predetermined range of st1 to st2, the motor is controlled to increase the torque of the motor from value 0 to a positive specified torque Tst1 and keep the torque of the motor at the specified torque Tst1 by a rate process using a rate value Tst1. When the predetermined condition is satisfied, a rate value Tst2 is set to increase with an increase in satisfaction time rotation speed Neset that denotes the rotation speed Ne of the engine on satisfaction of the predetermined condition. The motor is then controlled to decrease the torque of the motor from the specified torque Tst1 by a rate process using a rate value Tst2.
