In a hybrid vehicle provided with a continuously variable electric transmission mechanism capable of sequential shift mode, a minimum engine rotational speed is specified for each gear specified in the sequential shift mode so that the lower the gear, the greater the minimum engine rotational speed. When the engine rotational speed has decreased to the minimum rotational speed while driving in the sequential shift mode, an upshift lamp of a gear shift indication device is turned on to prompt the driver to manually shift to a higher gear. As the driver shifts to a higher gear in response to the prompt, the minimum engine rotational speed is specified to a lower value. That allows for further decrease of the engine rotational speed and improves fuel consumption rate.
