Abstract
A fuel-saving control device equipped with: a surplus drive force calculation unit for calculating surplus drive force; a fuel-saving control unit for executing a fuel-saving control which lowers and corrects the indicated fuel injection amount according to the accelerator position when the surplus drive force reaches or exceeds a threshold, and stopping the fuel-saving control when the surplus drive force falls below the threshold; a vehicle position detection unit for detecting the vehicle position; a map information storage unit for storing map information; a downshift operation detection unit for detecting a downshifting operation; and a forward gradient identification unit for identifying the forward gradient on the basis of the vehicle position and the map information. Therein, the fuel-saving control unit stops the fuel-saving control when a downshifting operation is detected and the forward gradient is an uphill grade equal to or greater than a threshold.
