Abstract
According to one embodiment, a vehicle includes a transmission, a brake pedal, and a controller. The controller is programmed to, in response to an upshift of the transmission, a driver-demanded torque being zero, and the brake pedal being released, command a first pressure, that is greater than zero, to an oncoming shift element associated with the upshift such that the oncoming shift element has a torque capacity of zero, in response to the brake pedal being applied during the upshift of the transmission, command a second, larger pressure to the oncoming shift element to increase the torque capacity to a non-zero value, and, in response to expiration of a threshold time from the brake pedal being applied, command a series of sequentially ramping pressures to the oncoming shift element to further increase the torque capacity and lock the oncoming shift element.
