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 (). 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.
