Abstract: Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

Abstract: To reduce fuel consumption, a transmission is shifted into a neutral state, called neutral idle, when a vehicle stops in a drive mode. During a transition from a neutral idle state to an engaged state, the engine torque is controlled to avoid excessive shift energy and to mitigate acceleration drop. Specifically, the engine torque is set to a level equal to a sum of a transmission torque capacity and an offset, which is a function of accelerator pedal position. The transmission torque capacity is calculated based on the engaging shift element torque capacity and torque ratios associated with the kinematics and the torque converter. To accommodate noise factors such as variation over time, the offset function is adapted in response to measured clutch energy and acceleration drop.

Abstract: Methods and systems are provided for improving engine restart operations in a hybrid vehicle. While an engine is cranked via motor torque, engine fueling is delayed until the engine speed is sufficiently high and the engine has been rotating in a forward direction continuously for a threshold duration. A disconnect clutch between the engine and motor is slipped while the engine cranks, the clutch engaged only after the engine has run up to the motor speed.

Abstract: A vehicle includes an engine with an associated engine-speed sensor, and wheels each having a respective wheel-speed sensor. The vehicle also includes a continuously variable transmission (CVT) coupled to the engine and configured to operate at variable input-to-output ratios. At least one controller is programmed to reduce the operating ratio of the CVT in response to the engine-speed sensor indicating the engine is operating at idle speed and the wheel-speed sensor indicating the velocity is approximately zero. This provides less noise, vibration and harshness in the vehicle due to the reduced ratio that is possible during conditions in which a vehicle launch in that reduced ratio may not be acceptable.

Abstract: Systems and methods for improving operation of a driveline disconnect clutch for a hybrid vehicle shifting are presented. In one example, pressure of a working fluid supplied to the driveline disconnect clutch is adjusted in response to a rate of change in accelerator pedal position. Further, pressure of the working fluid may be decreased responsive to selected operating conditions.

Abstract: Systems and methods for starting an engine of a hybrid vehicle are disclosed. The systems and methods disclosed may apply to series or parallel hybrid driveline configurations. In one example, engine cranking torque may be adjusted in response to a variety of operating conditions so that the engine may be started faster or slower.

Abstract: Systems and methods for operating a vehicle that includes a manual transmission are presented. In one example, a clutch actuator that responds to a position of a manual operated clutch pedal is adjusted to operate a clutch so that the vehicle may be stopped, while the engine is running or not, without the driver applying the clutch pedal.

Abstract: A manual transmission is partially automated by utilizing a controller to regulate the torque capacity of the clutch. Under most circumstances, the controller manipulates the clutch according to driver manipulation of a clutch pedal to simulate a non-automated manual transmission. However, to save fuel, the controller may enter a sailing mode in which the clutch is disengaged without the driver depressing the clutch pedal. The controller exits sailing mode in response to the vehicle speed decreasing below a threshold which is a function of the currently selected gear ratio. The threshold is selected such that the engine will not stall and will be able to generate sufficient power for acceleration when the clutch is re-engaged to exit sailing mode. In order to extend the use of sailing mode, the controller may activate a downshift indicator at a slightly higher speed threshold to encourage the driver to downshift.
