An engine torque control device is configured to lessen shift shock while
shortening the shift time during downshifting with an automatic
transmission. When a downshift requirement is generated, a disengagement
control of a higher gear clutch (current gear ratio) is commenced, and at
the same time, a first synchronizing control is commenced. The first
synchronizing control has a torque-up control with a first synchronizing
speed DNe1 set as the target speed TNe, during a first control period.
When the first control period has concluded and there is a transition to
a second control period. In the second control period, an engagement
control of a lower gear clutch (the post-shift gear ratio) is commenced,
and at the same time, there is a switch to a second synchronizing
control. In the second synchronizing control, the target speed TNe is set
to a second synchronizing speed DNe2 at the post-shift gear ratio.
