Classification: CPC B  F  Y | IPC B

Claim 16:
17. The control method of claim 1, further comprising:
determining, by the controller, a virtual vehicle speed from the actual motor speed detected by a motor speed detector and a preset virtual final gear ratio;
determining, by the controller, a virtual engine speed using the determined virtual vehicle speed and virtual gear ratio information of the virtual current gear shift stage;
comparing, by the controller, the virtual engine speed with a set threshold speed, determined, and determining that the virtual engine speed has entered a virtual red zone in response to determining that the virtual engine speed is greater than or equal to the threshold speed; and
generating, by the controller, a torque command for reducing the virtual engine speed by targeting the threshold speed and performing virtual fuel-cut control for adjusting a motor operation in response to determining an entry of the virtual red zone.
