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 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. The controller is adapted to shift the transmission from a forward drive mode into the NI state during a coast-down maneuver prior to the transmission reaching a zero output speed. A method of shifting the transmission into the NI state includes determining the presence of a predetermined one of the forward drive modes using the controller, and using the controller to actuate a designated one of the clutches as an NI clutch to enter the NI state during the forward drive mode, during a coast-down maneuver, and prior to the transmission reaching a zero output speed.

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： 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 control system for a vehicle having a dry dual clutch transmission (DCT) includes a launch condition detection module, a vehicle stop module, and a vehicle launch module. The launch condition detection module detects a launch condition based on whether (i) the vehicle is on an uphill grade and (ii) a driver of the vehicle has requested power via an accelerator. The vehicle stop module stops the vehicle when the launch condition is detected by (i) commanding an on-coming clutch of the dry DCT to a predetermined position and (ii) applying brakes of the vehicle. The vehicle launch module launches the vehicle after the vehicle is stopped by (i) fully engaging the on-coming clutch of the dry DCT and (ii) opening a throttle to a desired position corresponding to the power request.

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.
