摘要： An engine system of a vehicle includes an engine torque module. The engine torque module determines an engine output torque profile including predicted torque outputs based on an accelerator signal and an engine state variable. A load control module determines a dynamic transmission load profile based on the engine output torque profile and an engine speed profile. The dynamic transmission load profile includes transmission loads as a function of engine speed during an auto-start of an engine. A compensation module generates a torque compensation signal based on the dynamic transmission load profile. An actuator module compensates for a change in a transmission load based on the torque compensation signal and during a transition of the engine from a cranking state to an idle state.

摘要： A vehicle having engine stop-start functionality includes a transmission, engine, and controller. The transmission includes a clutch, and the engine includes a crankshaft. The controller is in communication with the engine and the transmission, and is configured for detecting a commanded shut down of the engine, and then engaging the clutch to control a rate of deceleration of the crankshaft and stop the crankshaft within a calibrated range of a target stop position at the end of engine shut down. A method for controlling engine stop position includes detecting a commanded shut down of the engine, and engaging the clutch after detecting the commanded shut down to thereby control the rate of deceleration of the crankshaft and stop the crankshaft within a calibrated range of a target stop position at the end of shut down of the engine. The transmission may be automatic or it may be a dual-clutch transmission.

摘要： An engine control system for an auto-stop/start vehicle, comprising: an actuator control module, a correction determination module, and a spark adjustment module. The actuator control module determines a target spark timing for a first time that is between a second time when engine cranking begins and a third time when a measured engine speed becomes greater than a predetermined engine speed after the second time. The correction determination module determines a spark timing correction for the first time based on a target engine speed and a measured engine speed. The spark adjustment module sets a spark timing for the first time based on the target spark timing and the spark timing correction.

摘要： A vehicle includes an engine that shuts down and restarts at idle, a dual-clutch transmission (DCT) having a controller and two input clutches for connecting the engine to respective evenly and oddly numbered gears of the DCT. The controller has a shift algorithm for shifting the DCT to achieve a predetermined engine load state during an engine autostart/autostop cycle, with the load state being unloaded or partially loaded. A DCT for the vehicle includes the input clutches and controller. A method includes shifting the DCT to the predetermined engine load state while the engine is off and an engine restart is commanded, and restarting the engine in the engine load state. The method may also include maintaining the clutches at a first point relative to a kiss point of the input clutches when the load state is unloaded, and at a second point when the load state is partially loaded.

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 of controlling a vehicle includes detecting vibration in a drivetrain of the vehicle with a fore/aft accelerometer during a launch event. An operating regime of the vehicle is identified concurrently with the detected vibration when the detected vibration is outside a predefined allowable range. A control strategy of the drivetrain is adjusted to define a revised control strategy to avoid the identified operating regime. The revised control strategy is applied to control the drivetrain to mitigate vibration in the drivetrain.

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. A method allows for direct entry into a neutral idle (NI) mode during a garage shift (GS) event using a multi-speed transmission. The method includes automatically actuating a first clutch of a plurality of clutches to complete the GS event, and a second clutch of the plurality of clutches to directly enter the NI mode after completing the GS event. The method may include holding the NI clutch at a pre-learned NI pressure during a fill stage of the GS clutch, and varying a turbine pull-down rate to provide different GS shift feels.

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.
