A transmission fluid circuit includes a transmission, a cooler, and a valve. The transmission receives and expels a fluid. The cooler receives and expels the fluid to the transmission. The valve directs the flow of fluid received from the transmission to one of the transmission and the fluid cooler. The valve includes a housing, a spool and an actuator. The housing defines a cavity. The spool is movable longitudinally in the cavity between a first position and a second position to direct the flow of the fluid from the cavity to the cooler or the transmission. The actuator is operatively connected to the spool and includes a smart material which is activated in response to the temperature of the fluid in the cavity having at least a first temperature and deactivated in response to the fluid in the cavity having a sufficient number of degrees less than the first temperature.

A system of a first vehicle includes a communication module, a translation module, a driver identification module, and an actuator control module. The communication module receives first vehicle control data generated based on operation of a second vehicle by a driver. The first and second vehicles are different. The translation module determines second vehicle control data based on the first vehicle control data and first characteristics of the first vehicle. The driver identification module selectively indicates when the driver is operating the first vehicle. During operation of the first vehicle by the driver, the actuator module controls at least one actuator of the first vehicle based on the second vehicle control data.

The present invention provides an apparatus and method for estimating the realtime position of a clutch piston during the fill cycle using noisy pressure measurements which ensures proper and desired clutch operation. Pressures on both sides of a flow controlling orifice, at the fluid control actuator and the clutch cylinder are measured and these measurements in conjunction with other system parameters such as orifice size, clutch volume and return spring characteristics are used to solve nonlinear dynamic equations (algorithms) which reside in a microprocessor. The microprocessor provides outputs corresponding to an estimate of the current position of the clutch piston, an estimate of the current speed of the piston and an estimate of the current hydraulic pressure. The method can also be utilized to detect clutch wear.

A system for absorbing vibration in a rotary member having a predetermined rotary speed of the present invention has a selectively moveable mass and a positioning mechanism. The mass is in communication with the rotary member having a predetermined position. The positioning mechanism exerts a force on the mass at least when the rotary member operates below the predetermined rotary speed. The force exerted by the positioning mechanism orients the mass at the predetermined position when the rotary member operates below the predetermined rotary speed.

A method for determining whether an accumulator is filled to a predetermined level with a hydraulic fluid includes commanding a current to a solenoid, providing pressurized hydraulic fluid to the accumulator, setting a timer to an initial value, incrementing the timer, determining if the timer is greater than a timer threshold value, measuring a current to the solenoid if the timer is greater than the timer threshold value, calculating a modified current as a function of the measured current, the timer value, and the commanded current, comparing the modified current to a threshold, and determining that the accumulator is filled to the predetermined level if the modified current is greater than the threshold.
