摘要：
A hydraulic system for controlling a belt-driven conical-pulley transmission of a motor vehicle having a variably adjustable transmission ratio, and having an electrical actuation system for overall control of the hydraulic system, and a hydraulic parking lock-release system to control a parking lock. In order to provide an improved hydraulic system, the parking lock includes a self-retention system in the event of an electrical power failure.
