  "textContent": "An engine torque control device is configured to lessen shift shock while shortening the shift time during downshifting with an automatic transmission (5). 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.",
