    • An improved control for an automatic transmission upshift, wherein the engine output torque and on-coming clutch pressure are coordinated during the shift based on an inverse dynamic model of the transmission to achieve a desired output torque trajectory. The desired output torque trajectory is influenced by operator demand, and an initial value of the desired output torque trajectory is used along with the engine output torque to develop an input acceleration trajectory. The inverse dynamic model of the transmission is used (1) to determine an engine torque command that will achieve both the input acceleration trajectory and the desired output torque trajectory, and (2) to determine a feed-forward pressure command for the on-coming clutch that will produce the input acceleration trajectory, given the engine torque command. The desired output torque trajectory and the engine output torque are used to determine the expected input speed, and a feed-back control term based on the deviation of the measured input speed from the expected input speed is used to adjust the on-coming clutch pressure command to account for model errors. Finally, the closed-loop feedback error is used to enable adaptive correction of the feed-forward control so that the feed-forward clutch pressure more nearly produces the commanded input shaft acceleration.

    • An improved speed indication method for a sensor that develops one or more electrical pulses per unit movement of a movable part, wherein the indicated speed is based on the number of speed pulses generated per unit time, but is constrained by a limit function based on the time elapsed without the generation of a speed pulse. When the pulse generation rate falls below the update rate of the speed indication, a maximum possible speed based on the duration of the “no pulse interval” is computed, and the indicated speed is reduced based on the computed maximum. When the next pulse occurs, the speed indication is updated based on the lower of a new speed calculation and the computed maximum speed. If speed pulses continue to be received, the computed maximum is no longer used as a limit, and the speed indication is updated in accordance with the pulse based speed calculation. As a result, the indicated speed provides a smoothly varying and more accurate representation of the shaft speed at very low speeds, enabling more accurate low speed control.

    • An improved control for an automatic transmission power-on downshift, wherein a dynamic model of the transmission is used to schedule the on-coming and off-going clutch pressures based on the transmission input torque and a desired trajectory of the input shaft during the shift. The shift is initiated with the off-going clutch by using the dynamic model achieve consistent initiation of clutch slippage, and to conform the input speed to the desired trajectory. When the input speed nears a synchronization speed for the target speed ratio, the dynamic model is used to engage the on-coming clutch at a rate based on the input torque while maintaining the input speed in synchronism with the target speed ratio. As a result, the control responds appropriately to dynamic changes in input torque, the input speed more accurately tracks the desired trajectory, and the shifts are completed at or near synchronism. Additionally, scheduling the clutch pressures based on the dynamic model achieves more consistent shift feel and improved adaptability to different powertrain and vehicle-type configurations while reducing the number of calibrated parameters requiring adaptive correction.

    • An improved control for an automatic transmission upshift, wherein the on-coming clutch pressure (Ponc) is scheduled during the torque and inertia phases of the shift in accordance with the summation of feed-forward and feed-back control terms, the feed-forward control term being developed using an inverse dynamic model of the transmission. The feed-forward control term is determined by developing a desired acceleration trajectory of the input shaft, and periodically applying the acceleration trajectory to the inverse dynamic model to obtain an estimate of the required on-coming clutch pressure, given the transmission input torque. The feed-back control term is based on a comparison of the expected input speed response with the actual input speed response, and corrects for modeling errors in the feed-forward control, providing disturbance rejection and improved command following. Additionally, the closed-loop feedback error is used to enable adaptive correction of the feed-forward control so that the estimated on-coming clutch pressure more nearly produces the commanded input shaft acceleration. Controlling the input shaft acceleration in this manner achieves more consistent shift feel and energy dissipation in the on-coming clutch, with less intensive calibration effort and improved adaptability to different powertrain and vehicle-type configurations.

The feed-forward control term estimates the force motor activation required to achieve the current command, based on the force motor temperature, the system voltage and a model of the force motor circuit. The feed-back control term compares an expected response to the actual response and develops a control term that corrects for modeling errors, providing disturbance rejection and improved command following.

    • An improved engine and transmission control method for coordinated control of closed-throttle transmission shifting, wherein the transmission control provides engine speed and torque rate limits to the engine control based on the shift parameters. The speed and/or torque rate limits come into play if the driver suddenly increases the engine throttle setting. Additionally, in driver requested garage shifts, initiation of the shift is prevented until the engine speed is within the speed limit. Preferably, the engine speed limit is set a calibrated amount above the computed input synchronization speed (SYNC). Alternately, the engine speed limit may be set to a value that limits the energy dissipated in the on-coming clutch to a predetermined value. With either approach, the engine speed and torque limits modify the engine control only to the extent necessary to preserve high shift quality while limiting the on-coming clutch energy dissipation to a safe level.

    • An improved automatic shift transmission control method establishes an initial methodology for sharing adaptive corrections among shift parameters stored for related types of shifts, and subsequently modifies the initial methodology as the adapted parameters converge on respective optimum values. Individual shift types are initially categorized to indicate the degree of cross-adaptive correction, and when shift parameter convergence occurs, the shift types are re-categorized, thereby modifying the initial cross-adaptive methodology to restrict further cross-adaptive correction. A given shift type is automatically reset to an initial or prior categorization to permit less restricted cross-adaptive correction if reset conditions are met. In this way, the methodology for sharing adaptive corrections automatically evolves to suit individual transmission operating characteristics and conditions, and effectively prevents degradation of a shift due to sharing of adaptive corrections developed for a related shift.
    • 改进的自动换档传输控制方法建立了用于在为相关类型的换档所存储的换档参数之间共享自适应校正的初始方法,随后随着适应参数收敛于相应的最佳值而修改初始方法。 单个移动类型最初被分类以指示交叉自适应校正的程度,并且当发生移位参数收敛时,移位类型被重新分类,从而修改初始交叉自适应方法以限制进一步的交叉自适应校正。 给定的换档类型自动重置为初始或先前的分类,以便在满足复位条件时允许较少受限的交叉自适应校正。 以这种方式,用于共享自适应校正的方法自动演变为适合各种传输操作特性和条件,并且有效地防止由于针对相关移位而开发的自适应校正的共享而导致的移位劣化。

    • An improved control for an automatic transmission closed-throttle downshift, wherein closed-throttle engine torque is used to raise the transmission input speed to the synchronous speed of the target speed ratio, and wherein the on-coming clutch is controlled in a manner to complete the shift with minimum driveline torque disturbance in spite of clutch control variability. The invention includes a primary on-coming clutch control for completing the downshift when the input speed reaches the synchronous speed, and a contingent on-coming clutch control that is initiated if shift completion is not achieved by the primary control, the contingent control being effective to re-establish input speed synchronization and thereupon engage the on-coming clutch to complete the shift. The primary clutch control involves holding the on-coming clutch in readiness for engagement while the input speed approaches the synchronous speed, and when the synchronous speed is reached, raising the on-coming pressure by a predetermined amount designed to maintain the input speed at the synchronous speed. The contingent clutch control includes a first open loop stage that progressively increases the on-coming clutch pressure to gradually re-establishing the input speed synchronization, and a second closed-loop stage that adjusts on-coming clutch pressure to conform the input speed to a defined trajectory.
