Hydraulic controller for an automatic transmission of a motor vehicle

A hydraulic controller and automatic transmission system of a motor vehicle, comprising:

• a gear shifting system that includes at least one gear shift piston-cylinder unit having a gear shift piston configured to actuate a shifting element;
• a gear shift pressure chamber configured such that an actuating pressure is built up in the gear shift pressure chamber;
• a centrifugal oil chamber separated from the gear shift pressure chamber by the gear shift piston, wherein the centrifugal oil chamber is configured to be supplied with operating fluid via a centrifugal oil line provided by a first supply line;
• a hydrodynamic torque converter situated in the first supply line;
• a second supply line configured to supply operating fluid to the centrifugal oil line, wherein the second supply line is configured to be closed and opened by a centrifugal oil valve;
• and
• hydraulic elements configured to set flow rates of the operating fluid, one of the hydraulic elements situated in the first supply line and avoiding excessive flow of operating fluid to the centrifugal oil chamber;
• wherein one other of the hydraulic elements is situated in the second supply line;
• and
• wherein the first supply line is connected to the centrifugal oil valve via two supply line sections, with one of the two supply line sections being blockable by the centrifugal oil valve and both of the supply line sections leading to the hydrodynamic torque converter.
