<P>PROBLEM TO BE SOLVED: To provide a start clutch control device of an idle stop vehicle which can reduce a time lag upon starting while preventing belt slip upon returning from idle stop. <P>SOLUTION: When an engine is restarted from an engine automatic standstill state, as control of engaging a start clutch, belt slip prevention control for supplying a clutch pressure so as not to cause a belt slip of a continuously variable transmission device, initial pressure control for supplying an initial pressure, and clutch pressure boosting control for boosting the clutch pressure with a predetermined temporal gradient are sequentially performed. When a belt compression exceeds a predetermined value, the belt slip prevention control is ended and boosting control for boosting a target clutch pressure to a pressure higher than the initial pressure is performed for a predetermined period, and after that, the initial pressure control is performed to thereby reduce a time lag upon starting. <P>COPYRIGHT: (C)2012,JPO&INPIT |
