Abstract

A method for characterizing a fluid control solenoid with current compensation is described. A current command is sent to the fluid control solenoid. The current command indicates a desired current value related to a desired fluid output pressure to be applied to the solenoid. An actual fluid output pressure is measured at a valve associated with the fluid control solenoid for the desired current value applied to the solenoid. An actual current received value at the fluid control solenoid is also measured. Post processing is then applied. A compensated current value related to the actual fluid output pressure is determined based on a difference between the current command and the actual current received value. Methods for dynamic current compensation are also described.
