Patent ID: 8631919

Claim:
Method to control a plurality of hydraulically actuated clutches in a transmission, the method comprising: monitoring a pressure within a first hydraulic circuit providing pressurized fluid to a first hydraulically actuated clutch with a first pressure sensor that is integrated substantially within a wall defining the first hydraulic circuit; providing a first closed-loop feedback control command for a first hydraulic control device providing the pressurized fluid to the first hydraulic circuit based upon the monitored pressure; controlling the first hydraulic control device based upon the first closed-loop feedback control command; monitoring a second pressure within a second hydraulic circuit providing the pressurized fluid to a second hydraulically actuated clutch with a second pressure sensor that is integrated substantially within a wall defining the second hydraulic circuit; providing a second closed-loop feedback control command for a second hydraulic control device providing the pressurized fluid to the second hydraulic circuit based upon the monitored second pressure; and controlling the second control device based upon the second closed-loop feedback control command; wherein controlling the second control device is further based upon the monitored pressure within the first hydraulic circuit.
