    Abstract: An electrified vehicle torque transfer system includes, among other things, an engine having an engine shaft, an electric machine having an electric machine shaft, a first clutch that is selectively engaged to rotatably couple together the engine shaft and the electric machine shaft such that the engine can drive rotation of the electric machine, and a second clutch that is selectively engaged to rotatably couple together the engine shaft and the electric machine shaft such that the electric machine can drive rotation of the engine.

    Abstract: A vehicle has an accelerator pedal in communication with a prime mover, a transmission, and a controller. The controller is configured to, in response to receiving a first input indicative of a vehicle state and a second input indicative of a curve along a vehicle path within a predetermined time interval, downshift the transmission and modify a driver torque request map associated with the accelerator pedal to reduce a percentage of pedal travel associated with positive drive torque. A method of controlling a vehicle includes downshifting a transmission and modifying a driver torque request map associated with an accelerator pedal to reduce a percentage of pedal travel associated with positive drive torque when a vehicle state and a curve from an electronic horizon system predict a vehicle lateral acceleration in the curve being above a first threshold value.

    Abstract: Powertrains may include a spring damper between the engine crankshaft and transmission input shaft. In some circumstances, an oscillation known as shuffle may occur in such powertrains. Active adjustment of engine torque is substantially more effective at mitigating shuffle oscillations if the engine torque includes a p-term proportional to displacement of the damper spring in addition to a d-term proportional to the speed difference across the damper. For various reasons, the spring displacement is difficult to measure directly. An observer algorithm is utilized to calculate a current estimated spring displacement based on a crankshaft speed sensor, a transmission input speed sensor, a wheel speed sensor, and past engine torques, using a dynamic model of the powertrain.

    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: An individual driving value is set as a function of an accelerator pedal position. In turn, a powertrain characteristic is set as a function of the individual driving style. The set powertrain characteristic may be modified on the basis of a feedback value corresponding to learned preferences of a driver. The modified powertrain characteristic is then either automatically implemented for operation of a powertrain or communicated as a choice for implementation. The feedback value is updated per a response to automatic implementation or choice communication.
