Abstract:
A pressure control system configured to control a selectable one-way clutch (SOWC) includes a pilot valve and a SOWC actuator. The pilot valve is configured to produce a pilot signal and includes a first valve, which is a MEMS microvalve. The pressure control system may further include a regulating valve in fluid communication with the pilot valve and configured to receive the pilot signal. The regulating valve is further configured to output a control signal. The SOWC actuator is configured to select between operating modes of the selectable one-way clutch in response to one of the pilot signal and the control signal.
