A method and system for an electronic engine control includes a strategy that correlates an accelerator pedal position with a selected, constant driveshaft power level regardless of changes in the transmission ratio. The invention includes adjusting the engine speed and torque so that the driveshaft torque both before and after the transmission shift remain the same if the accelerator pedal is at the same angle. The inventive constant power, part-load control strategy improves the smoothness of transmission shifts and fuel economy by creating a direct, consistent relationship between the pedal angle and driveshaft power level.
