Automatic transmission shift quality via selective use of closed-loop pressure feedback control |
摘要 |
A method to control a hydraulically actuated clutch in a transmission of a vehicle includes monitoring a pressure in a hydraulic circuit providing pressurized fluid to the hydraulically actuated clutch with micro-electromechanical pressure sensor, providing a closed-loop feedback control command for a hydraulic control device providing the pressurized fluid to the hydraulic circuit based upon the monitoring pressure, and controlling the control device based upon the closed-loop feedback control command. |
