Abstract
A system, comprising an engine having an electronically controlled throttle plate to adjust airflow to the engine; a transmission having an input speed and an output speed, the transmission including a clutch and the transmission coupled to the engine; and a controller configured to: during a tip-out condition and during a gear ratio change to a future gear, and when the transmission does not provide engine braking, control the engine speed to a synchronous speed in the future gear ratio by adjusting an engine operating parameter so that the engine speed is close to the engine speed that will be achieved after the gear change is completed, and maintain engine speed at the close engine speed after the gear change is completed until a tip-in, where engine speed is controlled by adjusting at least the electronically controlled throttle plate.
