摘要： A synchronous automatic transmission up-shift control utilizes input torque measurements. The input torque is measured during an up-shift having preparatory, torque, and inertia phases. Target input torque profiles for the torque and inertia phases are determined based on the input torque during the preparatory phase. During the torque phase, an engine torque is controlled to cause the input torque to achieve the target profile for the torque phase. During the inertia phase, an on-coming clutch is controlled to cause the input torque to achieve the target profile for the inertia phase.

摘要： A transmission and control method are disclosed which ensure proper stroke pressure and minimize torque transients during a shift event. The transmission includes a clutch having a torque capacity based on a fluid pressure, a torque sensor adapted to measure a torque value that varies in relationship to the torque capacity, and a controller. The method includes varying the fluid pressure around a predetermined value, measuring a resulting torque difference with the torque sensor, and adjusting a clutch control parameter if the resulting torque difference is less than a threshold value.

摘要： A system and method for controlling a vehicle powertrain includes a controller that is operative to automatically control at least one powertrain function other than engine torque based on a measured torque and a predetermined torque range. The predetermined torque range is based on a first engine torque estimate. The measured torque is related to actual engine torque, and can be measured directly at the engine crankshaft, or in another location in the powertrain and then transferred to the engine space.

摘要： A method for an automatic transmission includes measuring torque of a component of the transmission using a torque sensor in communication with the component. The torque of the component is estimated from information other than the measured torque. The measured torque is rejected from being used in a control operation of the transmission if the difference between the measured torque and the estimated torque is greater than a selected threshold.

摘要： A method of controlling a line pressure in a transmission is provided. Line pressure in a transmission is set to a pressure value including a first term that is proportional to an input torque value. The first term has a coefficient of proportionality that is increased in response to a signal indicating clutch slippage. The input torque value is a measured input torque value in a steady-state condition. The input torque value may be a maximum of the measured input torque value and a driver demand torque value in a transient condition.

摘要： A control system for a vehicle transmission includes a controller configured to output a first torque estimate defined in terms of one nonlinear function of a transmission parameter for a particular value of the transmission parameter. The controller also receives a measured torque of the transmission at the particular value of the transmission parameter, and outputs a modified torque estimate for the particular value of the transmission parameter based on the measured torque.
