Patent ID: 10920698

Abstract:
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 threshold, and stopping the fuel-saving control when the surplus drive force falls below the threshold; a direction indicator operation detection unit (107) for detecting operation of a direction indicator; a vehicle position detection unit (108) for detecting the vehicle position; a map information storage unit (109) for storing map information; and a fuel-saving control stoppage condition determination unit (110) for determining whether or not a fuel-saving control should be stopped, on the basis of the map information and the vehicle position when the direction indicator operation is detected. When determined that the fuel-saving control should be stopped, the fuel-saving control unit (102) stops the fuel-saving control even if the surplus drive force does not fall below the threshold.
