Abstract:
A vehicle control device has an engine, automatic transmission, and torque converter disposed between the engine and the automatic transmission. The torque converter includes a lockup clutch coupling an input member to an output member of the torque converter. The control device has: a slip control portion controlling lockup clutch slip when deceleration running; and a fuel cut control portion performing an engine fuel cut when deceleration running and to terminate the fuel cut when an engine rotation speed is reduced to a predetermined rotation speed or less during the fuel cut, the fuel cut control portion being permitted to perform the fuel cut, based on lockup clutch slip pressure controlled by the slip control portion has reached a slip pressure value at which the engine rotation speed does not decrease due to a shortage of torque capacity of the lockup clutch even when the fuel cut is performed.

Claim (Index 3):
The control device of a vehicle according to  claim 1 , further comprising a slip establishment time calculating portion configured to calculate a slip establishment time from a start of the slip control of the lockup clutch until reaching the slip pressure value of the lockup clutch at which the rotation speed of the engine does not decrease due to a shortage of torque capacity of the lockup clutch even when the fuel cut is performed, based on an output torque of the engine and an oil temperature, wherein\n the fuel cut control portion is permitted to perform the fuel cut of the engine when an elapsed time from the start of the slip control of the lockup clutch is equal to or greater than the slip establishment time.
