<P>PROBLEM TO BE SOLVED: To provide the idle stop mode control method of a hybrid car, which allows idle stop mode entry even when the deceleration of a vehicle is large, and attains improvement in fuel costs. <P>SOLUTION: This idle stop mode control method includes such steps that; when a hybrid car reaches an idle stop mode entry speed, and the deceleration is equal to or less than middle deceleration, engine RPM lift-up control is operated, and an engine RPM raises; gear variable speed hydraulic quantity is increased according as the engine RPM is increased, and the gear ratio of a CVT due to deceleration reaches the minimum target gear ratio; that when the gear ratio reaches the minimum target gear ratio, control for interrupting the idle stop mode entry by a TCU is not operated, and even when deceleration is equal to or less than middle deceleration, the idle stop model entry of the hybrid car is operated. <P>COPYRIGHT: (C)2009,JPO&INPIT |
