A fuel-saving control device (100) equipped with: a surplus drive force calculation unit (101) for calculating surplus drive force; a fuel-saving control unit (102) 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 first threshold, and stopping the fuel-saving control when the surplus drive force falls below the first threshold; a vehicle position detection unit (108) for detecting the vehicle position; a map information storage unit (109) for storing map information; a road information identification unit (110) for identifying the curvature radius and gradient of the road upon which travel is planned, on the basis of the vehicle position and the map information; and a flat/straight road determination unit (111) for determining whether or not the road upon which travel is planned is a flat and straight road, on the basis of the curvature radius and gradient of the road upon which travel is planned. Therein, the fuel-saving control unit (102) executes the fuel-saving control when the road upon which travel is planned is a flat and straight road.
