Abstract
A method and system for varying an output of a driveforce unit based on load data. The present invention includes an automobile including a driveforce system. The driveforce system includes a driveforce unit for generating an output according to a driveforce map, a memory for storing the driveforce map, a load determination unit for determining a load data indicating a load on the automobile, a speed sensor for detecting speed data indicating a speed of the automobile and/or an acceleration of the automobile, an acceleration input device for detecting acceleration input data indicating a percent application of the acceleration input device, and a processor. The processor receives the acceleration input data, the speed data, and the load data, and adjusts a driveforce curve in the driveforce map to maintain a speed of the automobile, even when the load data indicates an increased or decreased load on the automobile.
