PROBLEM TO BE SOLVED: To improve fuel consumption by restricting the condition for raising the propulsion ratio higher than aγmax balance propulsion ratio. SOLUTION: A primary sheave hydraulic pressure Pin and a secondary sheave hydraulic pressure Pd are controlled at a propulsion ratio higher than the balance propulsion ratio during normal control only when a condition in which the speed change ratio is a maximum speed change ratioγmax and a vehicle movement determination is being performed is satisfied without constantly increasing the balance propulsion ratio during the maximum speed change ratioγmax, and when the vehicle is completely stopped, the primary sheave hydraulic pressure and the secondary sheave hydraulic pressure are controlled at the balance propulsion ratio of normal control. As such, by limiting the condition when the propulsion ratio is raised higher than the balance propulsion ratio, fuel consumption can be improved. COPYRIGHT: (C)2011,JPO&INPIT |
