摘要： A method for cleaning a solenoid-operated regulator valve wherein command current applied to a solenoid actuator establishes a defined response of a valve. Cleaning current pulses applied to the solenoid establish a response that does not interfere with the effectiveness of the valve function. The pulse width, pulse amplitude, pulse direction and pulse period are determined by the degree of contamination of the valve environment.

摘要： A closed loop shift control apparatus and method based on friction element load controls a torque transfer phase when shifting from a low gear configuration to a high gear configuration for an automatic transmission system. When pressure actuated friction elements are selectively engaged and released to establish torque flow paths in the transmission, measurements or estimates of torsional load exerted on the off-going friction element are used to predict the optimal off-going friction element release timing for achieving a consistent shift feel. The ideal timing to release the off-going friction element is uniquely defined when torque load exerted onto the off-going friction element becomes substantially zero. An on-coming clutch engagement process is controlled by a closed loop control based on measurements or estimates of on-coming clutch torque capacity for a constant shift feel under dynamically changing conditions.
