PURPOSE: To reduce a body-sensing vibration due to surge which varies according to a shift position, in a device in which a control parameter of an internal combustion engine is controlled so that a torque variation value becomes a target torque variation amount.

CONSTITUTION: A shift position of a transmission connected to an internal combustion engine is judged (step 109), a map of target torque variation amount pre-set for each shift position according to the detected shift position, and the target torque variation amount are calculated from the selected map (step 110). The target torque variation amount is a target torque variation amount corrected according to the shift position, and set at a lower level near the resonance point of vehicle speed.
