Electrohydraulic controller for automatically controlled motor vehicle gearbox detects pressure tolerances by checking characteristics, produces and stores characteristic correction

摘要

The controller has a hydraulic unit (2) with hydraulic valves (4), sensors (6,7) and pressure regulators (5) as well as an electronic unit (3) with a microprocessor, memories, sensors and current regulators forming a functional unit. Pressure tolerances occurring in the working region are detected by checking characteristics, producing a characteristic correction from the deviations from a desired characteristic and placing in memory.
