<p><P>PROBLEM TO BE SOLVED: To prevent a driver from feeling incongruous due to generation of shock when fuel-cut is released and fuel supply is restarted at the time of increasing an engine rotation speed based on the torque capacity of a low-speed side friction engaging device with a coast down shift. <P>SOLUTION: The coast down shift is output (time t<SB>1</SB>) in a state where the fuel-cut is ON and the engine fuel supply is stopped. When the fuel-cut is OFF and the fuel supply is restarted (time t<SB>4</SB>) at the time of gradually increasing an oil pressure P<SB>C1</SB>of the low-speed side friction engaging device and increasing the engine rotation speed NE, the low-speed side friction engaging device reduces the oil pressure P<SB>C1</SB>to an oil pressure value just before having the torque capacity. Thereby, since the engine torque is cut off, the change of an output axis torque caused by the engine restart is suppressed and riding comfort is improved. <P>COPYRIGHT: (C)2004,JPO</p> |
