Abstract

An electro-hydraulic control system with electronic control for a gearbox includes at least one actuator element device for receiving an analog measuring signal from the actuator element(s), a device for forming an actual actuator value from the analog measuring signal for the regulation of the actuator element(s), a computing device with a memory, and an output driver. At least one A/D converter is provided to convert the actual analog actuator element value (U1) and/or the analog actuator element measuring value into a digital value. A digital two-step controller regulates the actuator element(s) by a cyclically-called comparison of theoretical and actual values.
