Abstract
An engine control device is provided, that includes an air amount controller, an ignition timing controller, a basic target torque determinator which determines a basic target torque, a change rate acquirer for acquiring a change rate of a steering operation, a target additional deceleration setter for increasing a target additional deceleration while an increase rate thereof becomes less as the change rate increases, a torque reduction amount determinator for determining an engine torque reduction amount, a final target torque determinator for determining a final target torque, and an actual air amount estimator for estimating an actual air amount introduced into a combustion chamber. The air amount controller determines a target air amount and controls the intake air amount to achieve the target air amount. The ignition timing controller retards the ignition timing more as the actual air amount becomes more excessive with respect to the target amount.
