摘要： 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.

摘要： A low noise, high efficiency solenoid pump includes a housing containing a hollow electromagnetic coil. Within the coil resides a pump assembly defining a tubular body having a pair of opposed ends which respectively include an inlet or suction port and an outlet or pressure port and within which a plunger or piston resides. The piston is biased in opposite directions by a pair of opposed compression springs. A first compression spring limits and arrests travel of the piston during the suction or return stroke and a second compression spring limits travel of the piston during the pumping stroke and returns the piston after the pumping stroke. The piston includes a first check valve that opens to allow hydraulic fluid into a pumping chamber during the suction stroke and closes during the pumping stroke to cause fluid to be pumped out of the pumping chamber. A second check valve opens to allow pumped fluid to exit the pumping chamber and the pump body through the outlet or pressure port and closes to inhibit reverse flow.
