Abstract: A method of adjusting a pressure signal to an actuator piston to control movement of a synchronizer actuator fork of a transmission includes moving the synchronizer actuator fork from a start position into a target position by applying an initial fluid pressure value. The time required to move the synchronizer actuator fork is measured to define a measured actuation time, and compared to a target actuation time. A correction factor is applied to the initial fluid pressure value to define a revised fluid pressure value when the measured actuation time is not within a pre-defined time range of the target actuation time. When the measured actuation time is greater than the pre-defined time range of the target actuation time, the initial fluid pressure value is increased. When the measured actuation time is less than the pre-defined time range of the target actuation time, the initial fluid pressure value is decreased.

Abstract: A transmission shift control system includes a transmission shift control module that executes an upshift or a closed-throttle downshift, a shift stage determination module, and a clutch control module. The stage determination module determines a stage of the upshift or the closed throttle downshift when a downshift is requested. The clutch control module determines a downshift type based on the stage of the upshift or the closed throttle downshift and selectively executes a downshift before the upshift or the closed throttle downshift is completed.

Abstract: A method reduces a time delay or lag between a commanded upshift and a resultant upshift event in vehicle. The method detects the commanded upshift, calculates a scheduled engine torque reduction torque value as a function of an unmanaged torque, and reduces an input torque value from the engine using the calculated scheduled torque. A powertain includes an engine, a transmission, a torque converter, clutches that are selectively engageable to provide at least six forward speed ratios, a reverse speed ratio, and a neutral condition, and a controller. The controller has an algorithm controlling an operation of an off-going clutch and the on-coming clutch during a speed ratio change representing an upshift event. The algorithm calculates a scheduled torque value as a percentage of an unmanaged torque level of the engine, and controls the off-going and on-coming clutch through the speed ratio change using the calculated scheduled torque value.

Abstract: A method for determining when in the course of a shift event an on-coming clutch gains torque capacity is provided. The method includes closed-loop controlling an off-going clutch to maintain a predetermined slip threshold by generating an off-going clutch pressure command, causing the on-coming clutch to engage during the closed loop control of the off-going clutch, generating a first derivative with respect to time of the off-going clutch pressure command, and using the first derivative to determine when the on-coming clutch gained torque capacity. A neural network method is preferably employed in analyzing the first derivative to locate a transition in the rate of commanded pressure indicative of off-going clutch release. A corresponding apparatus is also provided.

Abstract: The present invention provides a method and apparatus for adaptively controlling a closed throttle downshift in an automatic transmission wherein a transmission aberration during a shift is diagnosed and corrected during subsequent closed throttle downshifts. The invention is carried out by monitoring transmission characteristics including input speed, output speed and shift duration during a closed throttle downshift, and identifying departures from acceptable patterns. Each type of departure calls for a particular remedy, and a suitable adjustment is calculated based on the times and/or the commanded pressures at certain times, the adjustment being implemented by changing one or more initial conditions for the next shift of the same type. The adjustments may have to be large to make a full or significant partial correction at the next shift. Conversely small increments may be necessary to avoid over-correction.

Abstract: A system for a vehicle includes a desired pressure module, a valve actuation module, a filter module, and a capacity detection module. The desired pressure module selectively generates an increase in a desired pressure of hydraulic fluid for a clutch of an automatic transmission. The valve actuation module actuates a solenoid valve based on the desired pressure. The solenoid valve supplies hydraulic fluid to a regulator valve, and the regulator valve supplies hydraulic fluid to the clutch. The filter module filters an acceleration of a shaft of the automatic transmission to generate a filtered acceleration. The capacity detection module indicates whether the clutch reached torque carrying capacity based on the filtered acceleration.
