摘要： A control system of a power transmission mechanism, in which a transmission torque capacity between transmission members varies according to a pressure to be applied to the transmission members and in which the pressure to be applied to the transmission members is controlled on the basis of such a slip condition between the transmission members as accompanies the lowering of the pressure. The control system comprises: a pressure lowering device for lowering the pressure by a preset value; and a pressure setter for setting the pressure, in case the slip between the transmission members is not detected even by lowering the pressure by a preset value with the pressure lowering device, on the basis of the lowered minimum value of the pressure.

摘要： A control apparatus for a power train including a continuously variable transmission and a clutch arranged in series with the continuously variable transmission is provided in which an engaging pressure of the clutch is first reduced until a slip occurs, and is then increased after detection of the slip so as to re-engage the clutch, and an engaging pressure of the clutch to be established is calculated by giving an excess pressure to the engaging pressure at which the clutch is re-engaged, such that an excess amount of the transmitted torque of the clutch is set smaller than that of the continuously variable transmission. The control apparatus is adapted to determine a learned value as a correction value of the engaging pressure that is set in advance in accordance with an input torque applied to the clutch, based on the engaging pressure calculated by giving the excess pressure to the engaging pressure at which the clutch is re-engaged.
