Patent ID: 8180537

Claim:
An engine control apparatus for a vehicle equipped with a manual transmission, the engine control apparatus comprising: a shift operation detecting component configured to detect a manual shift operation; a vehicle speed detecting component configured to detect a vehicle speed; a transmission input side rotational speed computing component configured to compute an input side transmission rotational speed that is determined based on a vehicle speed and a gear ratio based on a shift position detected by the shift operation detecting component; a transmission input side rotational speed detecting component configured to detect an input rotational speed of the manual transmission; a clutch depression amount detecting component configured to detect if a depression amount of a clutch pedal is larger than a first prescribed depression amount that is equal to or larger than a depression amount corresponding to a disconnect position of the clutch, and to detect if the depression amount of the clutch pedal is larger than a second prescribed depression amount that is smaller than the depression amount corresponding to the disconnect position of the clutch; and a rotational speed synchronization control component configured to control an engine rotational speed to a target rotational speed by using the input side transmission rotational speed computed by the transmission input side rotational speed computing component as the target rotational speed when the clutch depression amount detecting component has detected that the depression amount of the clutch pedal during shifting is equal to or larger than the first prescribed depression amount, and the rotational speed synchronization control component being further configured to control the engine rotational speed to the target rotational speed by using the smaller of the input side transmission rotational speed computed by the transmission input side rotational speed computing component and an input rotational speed detection value detected by the transmission input side rotational speed detecting component as the target rotational speed, when the clutch depression amount detecting component has detected that the depression amount of the clutch pedal during shifting is smaller than the first prescribed depression amount and larger than the second prescribed depression amount.
