PROBLEM TO BE SOLVED: To provide a vehicle continuously variable transmission control device capable of preventing the occurrence of slip of a transmission belt when a shift lever is manipulated from a non-travel position to a travel position.SOLUTION: After garage-shift controlling a shift lever 64, switching control means (S3, S6, S7) switches a garage shift valve (selector valve) 120 on condition that hydraulic oil is charged in an input-side hydraulic actuator 34c, switches a hydraulic pressure of an advancement clutch C1 or a reverse brake B1 from a transitional hydraulic pressure Pg having a transitional rise to a preset module pressure (engagement keeping pressure) Pm and, at the same time, switches a state of supplying the hydraulic oil to the input-side hydraulic actuator 34c from an output oil passage of a secondary pressure control valve 104 to a state of applying an output pressure Pin of a primary pressure control valve 106. The problem of the slip of a transmission belt 40 is solved since the input-side hydraulic actuator 34c is filled with the hydraulic oil and the tension of the transmission belt 40 is maintained. |
