A method and system for operating a vehicle that includes a driveline disconnect clutch and a step-ratio transmission is described. In one example, the method includes shifting the step-ratio transmission to neutral and accelerating an engine to an expected input shaft speed of the step-ratio transmission via applying full output capacity of an electric machine to the engine.

Method and system for starting an engine

While a transmission range selector is in a Park position, a controller engages multiple transmission shift elements to place the transmission in a tie-up state. In the tie-up state, both the transmission output shaft and the turbine shaft are held against rotation by the shift elements. To transition from Park to Drive, the controller releases one of the shift elements to place the transmission in a 1st gear state. To transition from Park to Reverse, the controller releases a different one of the shift elements to place the transmission in a reverse state. The controller may wait until the driver releases the brake pedal to release the shift element.

Transmission and method of engagement

Methods and systems are provided for calibrating powertrain output in a vehicle. In one embodiment, a method for a vehicle comprises displaying a multi-parameter powertrain calibration map on a display device, and, responsive to user input, selectively adjusting the displayed calibration map along at least one parameter and not adjusting the calibration map past one or more predetermined thresholds. In this way, a vehicle powertrain system may be optimized according to a user's needs and/or preferences.

Methods and systems for powertrain control

A method for controlling a vehicle torque converter lockup clutch during a deceleration coasting event includes producing slip across the clutch by reducing the clutch's torque capacity, decreasing said slip by increasing said torque capacity, and maintaining slip across the clutch.
