    摘要： A hydraulic control system for a vehicle powertrain with an engine capable of being selectively turned on and turned off includes an accumulator, a plurality of fluid passages through which a fluid flows between the accumulator and a transmission associated with the powertrain, and a smart memory alloy (SMA) valve in fluid communication with at least one of the fluid passages. The SMA valve has a transition temperature. When the temperature of the fluid is less than or about equal to the transition temperature, the SMA valve closes, and when the temperature of the fluid exceeds the transition temperature, the SMA valve opens. When the SMA valve is closed, the accumulator cannot be charged with fluid, that is, the accumulator, does not fill with fluid, and when the SMA valve is open, the accumulator charges with fluid passively.

    摘要： A system and method for providing TCC control and/or transmission gear shift control by considering the rate of change of the accelerator pedal or throttle position. The method determines whether the rate of change of the throttle position exceeds a predetermined positive rate of change or a predetermined negative rate of change and, if so, releases the TCC to provide TCC control. Alternatively, or additionally, the method can provide a transmission gear down-shift or up-shift depending on which direction the throttle position is changing. Once the TCC and/or gear shift control has been initiated, the method can start a timer and then return to normal TCC and/or gear shift control after the timer has expired. The TCC and/or gear shift control can also return to normal if the rate of change of the throttle position indicates that the throttle is being returned to its previous position.
