Abstract
On condition that output of a torque of not lower than a preset reference torque from a motor continues for at least a predetermined time period in a vehicle stop state with output of a corresponding torque from the a second motor based on a detected accelerator opening, a torque command of the second motor is set to decrease the output torque of said motor by a torque decrease rate, which is set according to the corresponding torque and the accelerator opening in the vehicle stop state (initial accelerator opening). After a changeover of a current crowding phase in the second motor, the torque command of said motor is set to increase the output torque of said motor by a torque increase rate, which is set according to the accelerator opening in the vehicle stop state.
