<p>PURPOSE: To decrease shock to be generated caused by torque fluctuation in restoring of fuel cut by switching a clutch part from the direct connect state into the half clutch state before fuel injection is restarted from the fuel cut state in the deceleration. CONSTITUTION: In the fuel cut state in the deceleration, when the actual vehicle speed Vs is not more than the target vehicle speed Vso, even if the actual engine speed Ne is more than the fuel cut restoring engine speed Neo + a positive value K, a clutch 3 is made into the half clutch state from the direct connect state. Therefore, engine brake is effectively used, the restoration from the fuel cut is performed after the half clutch state, and shock generated caused by torque fluctuation in the restoration is decreased. On the other hand, when Vs>Vso and Ne<=Neo+K, the clutch is made into the half clutch state from the direct connect state at the time that Ne=Neo+K. The time of restoration from fuel cut at the time that Ne<=Neo is the time after the half clutch state, and shock generated caused by torque fluctuation in fuel cut restoration is decreased without being affected by the speed change schedule.</p> |
