<P>PROBLEM TO BE SOLVED: To provide an oil temperature control device for a vehicle capable of cooling automatic fluid with no influence of travelling condition and deteriorating the warming-up property of an ATF cooler with warmer function. <P>SOLUTION: While an oil passage for connecting an ATF cooler with warmer function and an ATF cooler is provided with a bypass oil passage for bypassing the ATF cooler, a switch control valve for carrying out selective switching of an oil passage on the basis of a control signal output from a control part is provided to a branch part of the oil passage and the bypass oil passage. The control part judges whether or not oil temperature of automatic fluid discharged from the ATF cooler with warmer function reaches a set temperature set in advance. When the oil temperature reaches the set temperature set in advance, the control part outputs the control signal for connecting the ATF cooler with warmer function and the ATF cooler. When not reaching the set temperature set in advance, the control part outputs the control signal for connecting the ATF cooler with warmer function and the bypass passage. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
