Patent
Belt type continuously variable transmission
TL;DR: In this paper, a controller is programmed to set a final pulley ratio achieved by a shift of the pulley ratios of the primary and secondary pulleys, based on the vehicle running state.
Patent
Hydraulic pressure control apparatus and method for continuously variable transmission
TL;DR: In this article, a line pressure of the continuously variable transmission is developed with a working oil supplied from an oil pump as an original pressure, and a command pressure is set to develop a line-pressure target value of the target value in such a manner that the command pressure was maintained at a predetermined small value for a constant time and, thereafter, the value of command pressure raised up to the target-value when a shift range of the continuous variable transmission was switched from a neutral range to a running range, the commandpressure being raised at a rate lower than a step input to suppress an
Patent
Hydraulic control apparatus and method for automatic transmission
TL;DR: In this paper, a line pressure regulator valve is used to regulate an oil pressure produced by an oil pump and set the line pressure, and a control unit is programmed to set the target value of the regulator valve to a value smaller than a maximum value.
Patent
Hydraulic controller of continuously variable transmission
TL;DR: In this article, the authors proposed a hydraulic controller of a continuously variable transmission capable of suppressing overshoot which occurs when line pressure of hydraulic fluid is risen to operate the continuously variable transmissions at the time that transmission range of the continuous variable transmission is changed from an N range to a D range.
