In one embodiment, when control of a throttle opening degree is limited due to the occurrence of an electronic throttle failure, a determination is made of whether or not an intake manifold negative pressure of an engine is inadequate, and when determined that intake manifold negative pressure is inadequate, a gear ratio of an automatic transmission is shifted (for example, downshifted) to a gear ratio that increases an intake pipe negative pressure, thus increasing the intake pipe negative pressure (absolute value).
