    摘要: A powertrain includes an engine, a transmission, and a torque converter located between the engine and the transmission. Subsequent to a rapid increase in engine torque commands, torque converter slip is controlled by monitoring a measured torque converter slip after the rapid increase in engine torque commands, determining a maximum measured torque converter slip value resulting from the rapid increase in engine torque commands based upon the measured torque converter slip, determining a target value to which to reduce the torque converter slip, determining a recovery profile to reduce the torque converter slip from the maximum measured torque converter slip to the target value, and utilizing the recovery profile to controllably reduce the torque controller slip. Determining the recovery profile includes commanding reducing slip through the profile at commanded torque converter slip values selected to prevent the torque converter slip from reaching zero.

    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.

    摘要: A method for adjusting the slip of a torque converter for a plurality of selected engine speeds, transmission gears and engine torque. A sensor is used to determine vibrations transmitted through the torque converter to the driveline of the vehicle. The sensor signal is sent to a controller where it is converted to the frequency domain. If the amplitude of the frequency signal exceeds a threshold, then the algorithm increases/decreases the converter slip until the driveline vibrations equal a threshold.

    摘要: A target pressure module determines a target pressure for controlling a solenoid of a transmission. An error module determines a pressure error based on a difference between the target pressure and a pressure measured using a pressure sensor. A pressure offset module determines a pressure offset using the target pressure and a mapping of pressure offsets indexed by target pressure. An offset learning module selectively determines a learned pressure offset and selectively updates the mapping based on the learned pressure offset. A pressure command module selectively generates a commanded pressure based on the target pressure, the pressure offset, and the pressure error. A solenoid control module controls actuation of the solenoid based on the commanded pressure.

    摘要: A system and method for transferring torque from a prime mover to a transmission includes a coupling device, a hydraulic control system and a control module. The coupling device includes a torque converter clutch (TCC), where the coupling device is located between an output of the prime mover and an input of the transmission. The TCC is actuated between a fully engaged position, a slip mode where slip occurs, and a fully disengaged position. The hydraulic control system includes a controller device that communicates an actuation pressure to the TCC. The actuation pressure actuates the TCC between the fully engaged position, the slip mode, and the fully disengaged position. The controller is in communication with the TCC, the output of the prime mover, the input of the transmission, and the controller device of the hydraulic control system. The controller regulates the actuation pressure.
