Abstract
An engine controller for controlling an internal combustion engine having a plurality of cylinders is provided. The engine controller is in signal communication with the internal combustion engine, an automatic transmission, and a displacement adjusting mechanism. The engine controller is configured to determine an operating condition of the internal combustion engine and to communicate with the automatic transmission to shift to one of a plurality of gear configurations, and the displacement adjusting mechanism to one of activate and deactivate at least one cylinder. The engine controller determines that a shift from a first gear configuration to a second gear configuration requires a positive torque when the at least one cylinder is deactivated. The engine controller communicates with the displacement adjusting mechanism to activate the at least one deactivated cylinder such that the plurality of cylinders are activated before the shift between gear configurations and the positive torque are completed.
