ABSTRACT:
A torque prediction module for an automatic transmission system includes a throttle-based torque prediction module. The throttle-based torque prediction module determines a first predicted torque of an engine in a vehicle that is based on a position of a throttle, an ambient air pressure, an intake temperature, and an engine speed. A torque offset module determines a torque offset that is based on the first predicted torque and a second predicted torque of the engine that is based on a mass airflow in an intake manifold of the engine. A blended torque module determines a third predicted torque of the engine that is based on the torque offset and the second predicted torque. A line pressure control module adjusts a line pressure of the automatic transmission based on the third predicted torque. An ECCC control module adjusts an amount of slip in an ECCC based on the third predicted torque.
