    摘要: A method of controlling an offgoing clutch in a transmission during a power downshift includes detecting the downshift, reducing a pressure command to the offgoing clutch, and introducing a calibrated error value to a pressure command for the offgoing clutch during the inertia phase. The method also includes synchronizing the speed of the offgoing and an oncoming clutch during the torque phase, determining the offgoing clutch pressure and torque after synchronizing clutch speeds, and then recording a clutch gain as a function of the offgoing clutch pressure and torque. The recorded clutch gains are used to control a subsequent power downshift of the transmission. A controller using proportional-integral-derivative (PID) control logic introduces the error as PID error in a pressure control signal, and controls slip across the offgoing clutch. A transmission is also disclosed having an offgoing clutch and controller configured to execute the above method.

    摘要: Clutch control values are determined via a method in a vehicle during a power-on upshift. Pressure to an offgoing clutch is decreased to a calibrated holding pressure after onset of the upshift. Proportional-integral-derivative (PID) logic of a controller is used to introduce a calibrated error into a pressure command to the offgoing clutch during fill of the oncoming clutch. This causes a calibrated slip to occur across the offgoing clutch, and a resultant threshold amount of flare to occur in turbine speed. The slip and flare are held using the PID logic. The pressure/torque relationship of the offgoing clutch is recorded. A fill level of the oncoming clutch is determined using a trajectory of an integrator term of the PID logic. A control value of the oncoming or the offgoing clutch is adjusted using at least one of the fill level, the recorded clutch pressure, and the recorded clutch torque.

    摘要: A vehicle including a transmission having a plurality of clutches for providing a plurality of speed ratios. A control module of the vehicle detects a possible tie-up of at least two of the clutches. Based on the detecting, the control module releases one of the possibly tied-up clutches. After the release, the control module determines whether a tie-up condition occurred. Based on the determining, the control module reapplies pressure to the released clutch. Loss of driver control of the vehicle thus can be prevented in the event of clutch tie-up.

    摘要: Clutch pressure of an oncoming clutch may be determined during an upshift in an automatic transmission by determining when offgoing and oncoming clutches of the transmission near a speed synchronization point. Aboard a vehicle, proportional-integral-derivative (PID) feedback control logic of for the oncoming clutch may be activated via a controller. The controller and the activated PID logic may be used to introduce a calibrated slip error between the rotational speeds of the offgoing and oncoming clutches. Engine speed is then held in a calibrated flare using the PID logic. Oncoming clutch pressure is recorded during the duration of the calibrated flare, and a control action is executed with respect to the transmission using the recorded oncoming clutch pressure, e.g., using recorded PID gains and/or a pressure/torque relationship of the oncoming clutch. A vehicle having an engine, transmission, and controller may use the controller to execute such a method.

    摘要: A method for determining the return spring pressure of a clutch in a vehicle transmission includes using proportion-integral-derivative (PID) control logic of a controller to introduce a calibrated error into a pressure command of a holding clutch during a coast-down maneuver of the vehicle. The calibrated error causes a slip level to occur across the holding clutch. The method includes maintaining the slip level using the PID control logic and separately commanding engine torque at different threshold low values during the coast-down maneuver. The pressure/input torque relationship for the holding clutch is recorded for both threshold low levels as the controller continues to maintain the slip. The return spring pressure is calculated using the recorded pressure/input torque relationship. The holding clutch may be controlled a subsequent shift maneuver using the learned return spring pressure. A vehicle is also disclosed having a controller configured to execute steps of the method.

    摘要: A method of managing slip in a transmission that is driven by a prime mover includes determining whether a slip condition of the transmission is present based on a slip value and reducing a torque output of the prime mover based on a torque reduction value when the slip condition is present. The method further includes storing the torque reduction value in an array if the slip condition is resolved as a result of the step of reducing and identifying a faulty component within the transmission based on the array.
