Abstract

A method and a device for controlling a fluid-actuated control system of an automatic or automated transmission of a motor vehicle, which has at least one pressure medium source, at least two control elements that are actuated by pressurized fluid and a control device for controlling the fluid-actuated control system. A further control module is used to reduce; the number and power consumption of valves that are actuated simultaneously to control the control elements; and the mechanical loading of the control elements (1, 2). The control module reads signals concerning at least one current control action and, in accordance with predetermined patterns, calculation rules and/or models, generates signals that cause non-switched control elements to be manipulated by pressurized working fluid.
