Patent abstract

An engine control apparatus basically has a clutch release detecting component, a time measuring component and a rotational speed synchronization control component. The clutch release detecting component detects when a clutch arranged between an engine and a manual transmission has been released to prevent rotation from being transferred from the engine to the manual transmission during shifting. The time measuring component measures an amount of time that elapses after the clutch is released. The rotational speed synchronization control component starts rotational speed synchronization control when the clutch is released and a prescribed delay time has elapsed since the clutch was released so that an engine rotational speed matches a predicted input rotational speed of the manual transmission being based on a vehicle speed and a gear position that is occurring after shifting is completed.
