摘要： A method for adaptively learning clutch volumes and fill level to compensate for build tolerances and clutch wear includes increasing a fill level of a clutch during an oncoming fill phase of a clutch to clutch transmission. A state of a regulator valve of the clutch to clutch transmission is monitored during the oncoming fill phase. Fill level of the clutch is adjusted before a next shift based on whether the regulator valve switches from a regulating state to a full feed state before elapse of a valid shift time.

摘要： A vehicle includes an engine, transmission, and controller. The transmission includes a clutch pack, a clutch piston, and a position sensor. The sensor measures a changing magnetic field with respect to the piston, and encodes the measured magnetic field as a raw position signal. The controller receives the raw position signal and processes the raw position signal through a signal processing module to generate a filtered signal attenuating signal noise in the position signal. The controller determines a commanded position of the piston, and calculates separate proportional (P), derivative (D), and integral (I) control terms using the commanded position and filtered position signal. The controller also calculates a feed-forward control term using the commanded position, and a required flow rate for actuating the clutch pack as a function of the PID terms and the feed-forward commanded position term. The controller actuates the clutch pack using the commanded flow rate.

摘要： A method of adjusting a pressure signal to an actuator piston to control movement of a synchronizer actuator fork of a transmission includes moving the synchronizer actuator fork from a start position into a target position by applying an initial fluid pressure value. The time required to move the synchronizer actuator fork is measured to define a measured actuation time, and compared to a target actuation time. A correction factor is applied to the initial fluid pressure value to define a revised fluid pressure value when the measured actuation time is not within a pre-defined time range of the target actuation time. When the measured actuation time is greater than the pre-defined time range of the target actuation time, the initial fluid pressure value is increased. When the measured actuation time is less than the pre-defined time range of the target actuation time, the initial fluid pressure value is decreased.

摘要： A method of controlling a transmission includes estimating an expected coefficient of friction of the clutch, estimating a value of an expected torque required to maintain a constant slip of the clutch for a current input torque applied to the transmission, and determining a value of an actual torque applied to the clutch to maintain the constant slip of the clutch at the current input torque. An actual coefficient of friction of the clutch is calculated by dividing the actual torque applied to the clutch by the expected torque applied to the clutch, and multiplying that quotient by the expected coefficient of friction of the clutch. A feed forward torque command is then adjusted based upon the actual coefficient of friction of the clutch to define a revised value of the feed forward torque command, which may then be used to control the clutch for various control operations.
