Beschreibung
Zusammenfassung:	A system for controlling fluid pressure to a transmission system through a MEMS microvalve includes a transmission controller configured to receive a target command pressure, a current system command pressure input signal, and a transmission system operating temperature. A power determination module determines a temperature-related power factor from the target command pressure, the current system command pressure input signal, the transmission system operating temperature received in the controller, and a look-up table within the controller. A power signal module adjusts the current system command pressure input signal by the temperature-related power factor and applies the adjusted current system command pressure input signal to the MEMS microvalve via the controller.
