Abstract
A method of camshaft scheduling is disclosed which includes measuring a driver input; calculating a driver requested torque based on a measured driver input; and scheduling the camshaft based upon the driver requested torque. In one example, the driver input is an accelerator pedal position, which is related to a percentage of driver torque requested. The cam position is selected based on the driver requested torque and the cam position is adjusted to provide one of a best fuel economy cam position and a best torque output cam position based upon the percentage of driver torque requested.
