Abstract: A vehicle includes an engine, an electric machine, a clutch, and a controller. The clutch is disposed between the engine and the electric machine. The controller is programmed to, in response to an engine start, close the clutch to transfer power from the electric machine to the engine to start the engine. The controller is further programmed to, in response to the engine start, control a torque capacity of the clutch during the engine start according to a model of a pressure applied to the clutch. The controller is further programmed to, in response to the engine start, control the torque of the electric machine based on an adjusted torque capacity of the clutch.

Abstract: A transmission includes a gearing arrangement configured to shift speed ratios by disengaging an off-going shift element and engaging an oncoming shift element and an electrohydraulic valve having an actuatable valve element configured to control an engagement state of the oncoming shift element. A controller is programmed to, during a shift of the transmission, in response to the off-going shift element disengaging and an expected ratio change not initiating, monotonically increase current to the valve to a maximum value to overcome frictional resistance on the valve element, and programmed to, in response to expiration of a timer and the ratio change still not initiating, send a repeating pattern of high and low current signals according to a duty cycle to overcome frictional resistance of the valve element.

Abstract: A vehicle includes an engine, an electric machine, a disconnect clutch, a starter motor, and a controller. The engine and electric machine are each configured to generate power to propel the vehicle. The disconnect clutch is disposed between the engine and the electric machine. The controller is programmed to, in response to a command to start the engine, operate either the disconnect clutch or the starter motor to start the engine based on a level of adaptive learning of previous disconnect clutch engagements.

Abstract: A vehicle includes a transmission having a plurality of friction elements selectively engageable to establish power flow paths within the transmission. A controller of the vehicle is programmed to, during a boost phase of a shift, command a first hydraulic boost pressure for a plurality of control loop cycles to an oncoming one of the friction elements (oncoming friction element) and subsequently command a second hydraulic boost pressure less than the first hydraulic boost pressure for only a single control loop cycle that defines an end of the boost phase to the oncoming friction element.
