Abstract
A hydraulic control apparatus for controlling a hydraulically hydraulically-operated power transmitting system for an automotive vehicle, the transmitting system having a continuously variable transmission and an auxiliary transmission coupled to an output side of the continuously variable transmission. The controlling apparatus comprises a first pressure generator for generating a first line pressure used to operate the continuously variable transmission, and a second pressure generator for generating a second line pressure used to operate a frictional coupling assembly incorporated in the auxiliary transmission.
