摘要： A method and apparatus provide control of a neutral idle (NI) clutch to allow a vehicle with automatic engine start-stop functionality to utilize the NI state as a transitional shift state, either upon or just prior to engine shutdown, to minimize driveline disturbances. By controlling the NI state, the vehicle driveline is decoupled and torque multiplication is prevented upon engine restart. Execution of an algorithm unloads the engine upon shutdown, and unloads or partially loads the engine as a designated NI clutch reapplies during an engine restart event. The NI clutch may be a component of a multi-speed automatic transmission, e.g., a 6-speed or an 8-speed transmission, having a plurality of torque transfer mechanisms or clutches. One of these clutches is designated as the NI clutch, and this designated NI clutch may be selectively actuated to enter the NI state in conjunction with engine shut down/restart.

摘要： A vehicle includes an engine, torque converter, transmission, accumulator, sensor, and controller. The engine is automatically restarted in response to a start signal during an engine auto-start event. The transmission has a calibrated line pressure and a plurality (n) of clutches. The (n) clutches are engaged to execute the engine auto-start event. The accumulator delivers fluid under pressure to the transmission in response to the start signal. The controller controls (n−1) of the plurality (n) of clutches to the calibrated line pressure in response to detecting the start signal. The controller also modifies clutch fill parameters which control a fill sequence of the remaining clutch, i.e., the designated control clutch, as a function of a deviation of the measured turbine speed from a theoretical no-slip turbine speed. A system includes the transmission, sensor, accumulator, and controller. A method for controlling the designated clutch is also disclosed.

摘要： A vehicle includes an engine, a multi-speed transmission with a neutral idle (NI) mode capability, and a controller. The controller allows direct entry into the NI mode during a garage shift (GS) event. One clutch is actuated during the GS event, and a different clutch is actuated to directly enter NI mode after completing the GS event.

摘要： A vehicle includes an engine, an automatic transmission, and a controller. The transmission includes a neutral idle (NI) state and a designated NI clutch which is selectively actuated to exit the NI state. The controller executes instructions from tangible memory to shift out of the NI state and into a drive state. The controller includes a slip model which generates a desired clutch slip profile as a differentiable time function, and a desired slip derivative of the desired slip profile. The desired profiles are used to calculate a clutch pressure command for controlling the designated NI clutch. The time function may be at least a third order/cubic equation. A method includes executing the slip model to generate the desired clutch slip profile, calculating a desired slip derivative of the desired slip profile, and using the desired slip profile derivative to calculate a clutch pressure command for the designated NI clutch.

摘要： A transmission control system for a vehicle includes a transmission control module (TCM), a solenoid valve, a pressure regulator valve, and a transmission element. The TCM includes a control algorithm providing output signals to valve drive electronics, where the valve drive electronics supply current to the solenoid valve. The solenoid valve controls an output pressure located in a passage between the pressure regulator valve and the transmission element. During an engine start-up condition of the vehicle, the control algorithm of the TCM includes control logic for activating a solenoid adjustment algorithm. The solenoid adjustment algorithm decreases the sensitivity of the valve drive electronics when supplying current to the solenoid valve. The solenoid adjustment algorithm is activated for a predetermined amount of time after engine start-up, and is then terminated. Alternatively, the solenoid adjustment algorithm is activated until a vehicle operating condition reaches a particular value, and is then terminated.

摘要： A method adaptively learns torque converter (TC) slip in a transmission having a hydrodynamic torque converter assembly by setting a baseline TC slip profile, determining an actual TC slip value at different temperatures, generating an adapted TC slip profile by adapting the baseline TC slip profile in response to the actual TC slip values, and controlling the amount of TC slip during a neutral idle (NI) state of the transmission using the adapted TC slip profile. A vehicle includes a torque converter and a controller. The controller calibrates the TC slip during a first transmission state, and controls the amount of TC slip during a second transmission state. The controller measures actual TC slip data points, and adapts a TC slip profile to more closely approximate a natural slip curve of the vehicle in response to the actual slip TC slip value data points.

摘要： A transmission includes a plurality of clutches that are selectively engageable alone or in combination with each other to establish a plurality of forward drive modes, wherein one of the clutches is configured as a neutral idle (NI) clutch that is selectively actuated to shift the transmission into an NI state, and a controller.
