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.

摘要： An example vehicle includes a motor and a gearbox. A controller is configured to identify oscillation peaks of a performance signal representing the rotational speed of the motor, the input speed of the gearbox, or the amount of torque generated by the motor or provided to the gearbox. The controller is configured to simultaneously detect unstable regular and irregular oscillations of the performance signal given the oscillation peaks identified and substantially dampen the unstable oscillations detected. An example method may include determining a mean of the performance signal and defining peak values, including peak moving average values or filtered peak values, representing a magnitude of at least two oscillation peaks. The method further includes simultaneously detecting the unstable regular and irregular oscillations of the performance signal using the defined values and substantially dampening the unstable oscillations.

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： 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.
