Method for Determining an Adjustment Parameter for a Hydraulic Actuator Arrangement in a Motor Vehicle Drivetrain

摘要

Method for determining an adjustment parameter in a hydraulic actuator arrangement for a motor vehicle drivetrain. The actuator arrangement has a pump and a hydraulic cylinder. A pressure port of the pump is connected to a port of the hydraulic cylinder. The adjustment parameter is a function of the volume of the fluid that must be delivered by the pump in order to realize a predetermined operating point of the actuator arrangement. The operating point is defined by a value pair of an operating point rotational speed value of the pump and an operating point control value of the pump. The method has the steps: regulating the pump to the operating point rotational speed value such that the pump delivers a fluid volume flow rate corresponding to the operating point rotational speed value; and integrating the fluid volume flow rate over the time until a termination operating state of the actuator arrangement, in which the control value of the pump is less than or equal to the operating point control value.
