IPC: F16H61/04
Filed: 2001-09-07
Abstract: PROBLEM TO BE SOLVED: To improve traveling performance in inertial traveling on an downward slope. SOLUTION: A continuously variable transmission continuously changes rotation of an input-side rotation body through a power transmission element and transmits the rotation to an output-side rotation body. When a vehicle has not less than a prescribed acceleration/deceleration in a state that an inertial traveling detection means detects the inertial traveling of the vehicle on the downward slope, a lower limit value of a target rotation speed for the inertial traveling of the input-side rotation body is set. When the inertial traveling is released, the lower limit value is corrected on the basis of a vehicle speed and an opening of a throttle in a state wherein the vehicle has not more than the prescribed acceleration/deceleration.  When the inertial traveling is released, a lower limit value change ratio of the target rotation speed for the inertial traveling is corrected on the basis of the vehicle speed in the state below the prescribed acceleration/deceleration.
