    Abstract: A clutch system comprises a hydraulic control circuit for controlling a hydraulic system. The hydraulic control circuit comprises processor-executable control instructions to perform a method for controlling hydraulic pressure. The method comprises receiving a target hydraulic pressure. The method generates and outputs pressure control valve commands based on a detected current hydraulic pressure, a detected temperature, and the target hydraulic pressure by implementing proportional integral derivative (PID) calculations and sliding mode calculations while carrying out a closed loop pressure control. The method converts the target hydraulic pressure into motor speed control commands and into motor direct current commands by implementing a linear quadratic regulator (LQR) calculation while carrying out a closed loop speed control. The method controls the electric motor using the motor direct current commands. And, the method controls the pressure control valve by using the pressure control valve commands.

    Abstract: An automatic control strategy for use with a multiple-ratio transmission in an automotive vehicle driveline in which the crankshaft (14) of an internal combustion engine (12) is connected directly to torque input elements of a multiple-ratio gearing (10,22,24) without an intervening hydrokinetic torque converter. The strategy is adapted especially for use with a wet auto clutch to provide forward or reverse drive engagement during vehicle launch and during transient damping of driveline disturbances. The strategy makes it possible to control the clutches (116) to achieve maximum vehicle acceleration by controlling the engine speed so that it operates at maximum torque throughout the useful engine speed range for any given engine throttle position. The entry and exit conditions for each drive mode are determined by the strategy so that optimum drive-away performance and optimum shift control, as well as soft clutch engagement and full clutch engagement, can be achieved.
