摘要： An improved method and apparatus for estimating driveline lash in a vehicle powertrain is provided herein. The method includes: determining if the powertrain is transitioning through driveline lash, e.g., driver commanded torque value changes sign, and then stays between a minimum and maximum commanded torque threshold for a calibrated time; if the powertrain is transitioning through driveline lash, determining when the driveline lash is taken up, e.g., when the transmission output acceleration exceeds a threshold minimum output acceleration, and thereafter changes sign; determining when the estimated lash state changes from neutral to a positive or negative state, which may be inferred from the axle torque estimate behavior; determining the time difference between when the driveline lash is taken up and when the estimated lash state changes from neutral to a positive or negative state; and updating the adaptive lash estimate if the aforementioned time difference is not equal to zero.

摘要： The present invention provides an improved method and apparatus for regulating active damping in a hybrid vehicle powertrain. The method includes: monitoring the damping command sent to the active damping system; determining a mean reference point, which may be a filtered value of the damping torque command; determining if the unfiltered damping torque command value switches from one side to the other of the mean reference point; if a switch is detected, determining if the size of the switch exceeds a predetermined minimum; if it does, then increasing a total number of switches; determining if the total number of switches exceeds a switch threshold; if the total number of switches exceeds the switch threshold, determining if the current damping torque exceeds a damping torque threshold; and decreasing the damping torque if the total number of switches exceeds the switch threshold and the current damping torque exceeds the damping torque threshold.

摘要： A method for optimizing a shift event in a vehicle includes designating a clutch to be used as an oncoming clutch or an offgoing clutch in the shift event before executing the shift event, and processing a plurality of input values through a state observer to thereby determine, as an output value of the state observer, an estimated slip speed of the designated clutch. The method includes using a proportional-integral control module for the designated clutch (a clutch PI) to close the control loop on the estimated slip speed from the state observer, thereby smoothing a switching between state space equations in the state observer, and executing the shift event. A vehicle includes a transmission, an engine, at least one traction motor, and a control system configured for executing the above method.

摘要： The present invention provides an improved method and apparatus for regulating state variable estimators used in a hybrid active damping system for a vehicle powertrain. The state estimator provides variable estimates for operating states, such as real-time torque values of axles and dampers, that are not readily measurable with production powertrain and driveline hardware. This facilitates implementation of other control algorithms, such as torque oscillation damping control schemes which use multivariable feedback. The apparatus and method monitors the operating mode of the powertrain, and resets the state estimator for the hybrid active damping ring (HADR) under predetermined operating conditions. For instance, the state estimator includes an array of current state and predicted state variables that are set equal to corresponding reference values or measured values if the powertrain enters into four-wheel drive low (4WDLO).

摘要： A method for optimizing torque control in a vehicle having a controller and a rotating member includes generating a closed-loop total proportional torque command using a state space feedback portion of the controller, and splitting the total proportional torque command into high-frequency and low-frequency proportional torque components. A total proportional torque is passed to the rotating member to provide driveline damping control when speed control is not required. The high-frequency proportional torque component is passed to the rotating member to provide driveline damping control, and the low-frequency torque component is passed with a total integral torque command to the rotating member to provide speed control, when speed control is required. A vehicle includes a controller having proportional-integral control capabilities and a state space observer, and a powertrain having a rotating member whose speed and damping characteristics are controlled by the controller.
