Abstract
A vehicle control system includes a variable displacement internal combustion engine, a transmission coupled to the variable displacement internal combustion engine, an intake manifold coupled to the variable displacement internal combustion engine, a throttle coupled to the intake manifold, an engine controller for controlling the throttle and the variable displacement internal combustion engine, and a transmission controller for controlling the transmission. The engine controller transfers a throttle position or load value to the transmission controller. This throttle position or load value is independent of the actual displacement of the variable displacement internal combustion engine.
