<P>PROBLEM TO BE SOLVED: To provide a shift control system of an automatic transmission for effectively preventing a rise in an oil temperature. <P>SOLUTION: When hydraulic pressure supplied to a primary pulley cylinder chamber 10c and a secondary pulley cylinder chamber 11c is a prescribed temperature or more and a vehicle speed is a prescribed speed or more, torque is reduced by restricting output torque of an engine, and the hydraulic pressure is also adjusted according to input torque inputted to a belt type continuously variable transmission. Thus, the vehicle speed is reduced, and friction is reduced, and a drop in the oil temperature can be quickened. The friction of an oil pump 80 for generating the hydraulic pressure can be reduced by reducing the hydraulic pressure according to the input torque, and a further drop in the oil temperature can also be quickened since contact frictional force can be reduced when sandwiching a V belt by a pulley. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
