Patent attributes
A control apparatus for a vehicular continuously variable transmission is provided. The control apparatus includes a pair of pulley pressure adjusting valves, a pair of electromagnetic valves, a source pressure adjusting valve and an electronic control unit. The electronic control unit is configured to control the source pressure adjusting valve in such a manner as to lower the source pressure at a time of a fail mode below the source pressure at a time of a non-fail mode, at the time of the fail mode, and control command signals to the pair of the electromagnetic valves such that the command signals temporarily decrease below command signals at the time of the non-fail mode, before cancelling the lowering of the source pressure in making a changeover from the fail mode to the non-fail mode.
