Abstract
A vehicle powertrain includes an engine and a transmission, each controlled by controllers that communicate with one another. When the vehicle is coasting in certain gears, a one-way clutch over-runs. When the driver depresses the accelerator pedal (tips in), the transmission controller adjusts a transmission torque demand limit which is communicated to the engine controller. In response, the engine controller adjusts the engine torque, resulting in a smooth re-engagement of the one-way clutch.
