Method for determining operating mode of hydraulic variator utilized with continuously variable transmission, involves determining operating mode of device when difference theoretical and actual values of current is greater than threshold

摘要

The method involves determining an actuating variable of a regulator based on a deviation between actual and target values of position control current. A position control operating mode of a device (1) for varying stroke volumes of two hydraulic machines is determined during presence of a difference between a theoretical value of the current and the actual value greater than a predefined threshold of a high-pressure control operating mode and/or during presence of the difference smaller than another predefined threshold. The variable is transmitted to a real-time model.
