摘要： A dynamic model is stored in memory that defines torque transmitted by the lockup clutch as a function of a plurality of torque converter operating parameters. A lockup clutch command is asserted to control engagement the lockup clutch, and thereafter a number of the plurality of torque converter operating parameters are monitored. A profile is selected of one of the plurality of torque converter operating parameters, and the profile is configured to result in an intersection of rotational speeds of the pump and the turbine over time when inserted into the model along with the monitored values of the number of torque converter operating parameters. The model is continually solved over time using the selected profile and the monitored operating parameters to produce transmitted torque values, and the lockup clutch command is modified based on the transmitted torque values.

摘要： An engine control for a motor vehicle powertrain coordinates engine speed and torque limiting during automatic transmission range changing so as to provide both vehicle rocking capability and adequate protection for the transmission. A transmission controller temporarily limits the engine speed to a predetermined value on each transition to or from the forward or reverse ranges, and superimposes continuous engine speed and torque limitations when an abusive rocking maneuver is detected. An abusive rocking maneuver is detected when the driver commands at least a specified number of successive range shifts during a predetermined time interval, and the speed and torque limitations are imposed until range shifting is discontinued for at least a calibrated period of time.

摘要： A method of releasing a lockup clutch for a fluid coupling assembly disposed between an engine and an automatically shiftable transmission during a negative engine torque mode of operation is provided. The method includes the steps of: A) determining a current engine torque value prior to commanding the engine to ramp to a target engine torque value; B) commanding the engine to a target engine torque value wherein the target engine torque value is one of a zero and near zero value; C) holding the engine at the target engine torque value; and D) releasing or disengaging the lockup clutch when the engine is operating at the target engine torque value. A powertrain is also provided having a controller sufficiently configured to operate according to the method of the present invention.
