Abstract

A control apparatus for a vehicle that includes: drive wheels; an engine; a flywheel damper connected to the engine; at least one inertial body provided between the flywheel damper and the drive wheels; and a clutch for connecting and disconnecting between the flywheel damper and the at least one inertial body. In a process of reduction of a rotational speed of the engine for stopping the engine, the control apparatus keeps the clutch engaged until the rotational speed has passed through a first resonance speed range, and causes the clutch to be released before the rotational speed reaches a second resonance speed range. The first resonance speed range is a range of the rotational speed in which resonance is generated with the clutch being released. The second resonance speed range is a range of the rotational speed in which the resonance is generated with the clutch being engaged.
