摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control system for a transmission for a vehicle that suppresses an influence on the durability of an object to be controlled by an actuator when discharging foreign matters having entered a circuit.
SOLUTION: The hydraulic control system includes a satisfaction-of-condition judgment means 132, a foreign matter discharge control execution means 134, and a hydraulic control means 136. The satisfaction-of-condition judgment means 132 judges whether predetermined conditions for executing the control of a discharge of the foreign matters are satisfied or not. The foreign matter discharge control execution means 134 forcibly moves a valve element of a linear solenoid valve SLS by changing exciting current of a solenoid 110 according to a predetermined current command value for discharging the foreign matters when the judgment by the satisfaction-of-condition judgment means 132 is affirmed. The hydraulic control means 136 controls so that a line pressure P
L input to a clamping force control valve 86 is smaller than a pressure regulation value P
BELT of the clamping force control valve 86 during execution of the foreign matter discharge control by the foreign matter discharge control execution means 134. Thus, it is possible to prevent the output hydraulic pressure P
BELT output from the clamping force control valve 86 from being transitionally increased during an execution of the foreign matter discharge control.

摘要： PROBLEM TO BE SOLVED: To provide a control device of a vehicle, which suppresses the slippage of a belt when a garage shift in which shift operation is performed from a non-traveling position to a traveling position is performed when a traveling drive force source is started in a state where defective belt return occurs. SOLUTION: When a gear shift control pressure P RATIO is not filled up when the garage shift is performed in the state where a transmission belt 48 is not returned to the maximum deceleration position, a linear solenoid valve SLT is controlled by a hydraulic pressure lowering control means 170 so that the control hydraulic pressure P SLT fed to a clutch C1 for forward movement or a brake B1 for backward movement is temporarily lowered more than the hydraulic pressure according to a predetermined rule. Since the engine torque T E inputted (transmitted) to a continuously variable transmission 18 is lowered, the slippage of the belt when the garage shift is performed in the state where the transmission belt 48 is not returned to the maximum deceleration position is suppressed.

摘要： PROBLEM TO BE SOLVED: To attain a control capable of surely maintaining the change gear ratio of a continuously variable transmission at a maximum change gear ratio γmax while suppressing deterioration of fuel consumption in speed change for stopping a vehicle or slow traveling of the vehicle.
SOLUTION: When vehicle speed is a determination threshold B or less, and the change gear ratio of the continuously variable transmission is a determination threshold B or more, establishment of a maximum change gear ratio determination condition is determined, and lower limit guard processing of primary sheave oil pressure is released to reduce the primary sheave oil pressure to the oil pressure of a primary-side hydraulic actuator in general control or less. By such a control, the change gear ratio of the continuously variable transmission can be surely maintained at the maximum change gear ratio γmax when stopping the vehicle. Additionally, since the change gear ratio can be set to the maximum change gear ratio γmax without rise of secondary sheave oil pressure, fuel consumption can be improved. Further, increase in change gear ratio is prevented in slow traveling, and a starting failure by insufficient driving force can be avoided.
