Abstract: An output is calculated using, as an input, a measured value of a pump discharge pressure in a neural network having the pump discharge pressure as the input and a pump rotational speed as the output. A leakage degree of oil of the hydraulic circuit of a transmission is estimated based on a difference obtained by subtracting a measured value of the pump rotational speed from the calculated value of the output. Learning of the neural network is performed using, as teacher data, the measured values of the pump discharge pressure and the pump rotational speed in the transmission in which the leakage degree of oil is within an allowable range.

Abstract: Disclosed is a hydraulic control device for a continuously variable transmission which changes the transmission gear ratio by changing the hydraulic pressure supplied to hydraulic pressure chambers for pulleys in the continuously variable transmission via control valves is changed. In this hydraulic control device, line pressure regulation hydraulic pressure which corresponds to the magnitudes of the oil pressure supplied to the hydraulic pressure chambers is introduced into a regulator valve, and line pressure which is input into the control valves according to the magnitudes of the oil pressure is subjected to feedback regulation. In the hydraulic control device for the continuously variable transmission, after the valve element of the control valve is driven in the valve opening direction, a vibration restriction control operation which temporarily restricts the displacement of the valve element is executed.

Abstract: A control device for an automatic transmission including a hydraulic actuator that is actuated on the basis of a hydraulic pressure supplied and a linear solenoid valve that controls the hydraulic pressure supplied to the hydraulic actuator on the basis of a driving current of a solenoid includes an ECU that executes current feedback control over a current value of the driving current that is flowed to the solenoid using at least a proportional term and an integral term on the basis of a deviation (?I) between a target current value (Itgt) and actual current value (Ir) of the solenoid such that the hydraulic pressure supplied to the hydraulic actuator becomes a target hydraulic pressure. The ECU increases a proportional gain (Kp) in the current feedback control as a fluid temperature (To) detected by a fluid temperature sensor increases.

Abstract: A hydraulic device includes a switch-over valve 1140 provided at a section of a sub-passage 1105 located downstream of a location where a first bypass passage 1117 is connected and located upstream of a primary regulator 1110. The switch-over valve 1140 is switched between a blocked state, where supply of hydraulic oil to a section of the sub-passage 1105 located downstream of the switch-over valve 1140 is blocked, and a communication state, where supply of hydraulic oil to the section of the sub-passage 1105 located downstream of the switch-over valve 1140 is permitted. In the hydraulic device, when the switch-over valve 1140 is switched to the communication state, as a discharge performance of a main pump 1102 increases, a first check valve 1118 closes. Supply paths for hydraulic oil discharged from the sub-pump 1103 are automatically switched in accordance with the discharge performance of the main pump 1102.
