Abstract
A fuel-saving control deviceequipped with: a surplus drive force calculation unitfor calculating surplus drive force; a fuel-saving control unitfor executing a fuel-saving control which lowers and corrects the indicated fuel injection amount according to the accelerator position by using a lowering-correction value that corresponds to the surplus drive force when the surplus drive force reaches or exceeds a prescribed threshold, and stopping the fuel-saving control when the surplus drive force falls below the prescribed threshold; a vehicle position detection unitfor detecting the vehicle position; a map information storage unitfor storing map information; and a forward curvature radius identification unitfor identifying the forward curvature radius on the basis of the vehicle position and the map information. Therein, the fuel-saving control unitprevents the lowering-correction value from varying by a prescribed degree of variability or more when the forward curvature radius is less than the prescribed threshold.
