    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 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 method for controlling actuation of a torque converter clutch includes monitoring a transmission input speed, comparing the monitored transmission input speed to a threshold input speed, and, when the transmission input speed is less than the threshold input speed, controlling an engine speed based upon a desired minimum engine speed. Controlling the engine speed based upon the desired minimum engine speed includes monitoring a minimum engine speed critical parameter, determining the desired minimum engine speed based upon the minimum engine speed critical parameter, comparing the engine speed to the desired minimum engine speed, and controlling actuation of the clutch device based upon a result of the comparing the engine speed to the desired minimum engine speed.

    摘要: A system and method for setting the slip of a torque converter for a plurality of selected engine speeds and transmission gears. The method includes populating a table off-line, typically using a dynamometer, with torque converter slips for a plurality of selected engine speeds and transmission gears. A speed sensor is used to measure vibrations transmitted through the torque converter to the driveline of the vehicle. The sensor signal is sent to an analyzing system where it is converted to the frequency domain. A separate minimum slip value for each selected engine speed and transmission gear is stored in a table so that during vehicle operation, a controller will instruct the torque converter clutch to set the desired converter slip for the current engine speed and transmission gear provided for a particular throttle position and/or engine torque.
