<p>PROBLEM TO BE SOLVED: To provide a fuel supply control device capable of improving both of fuel consumption of an internal combustion engine, and running quality.SOLUTION: In an ECM (Engine Control Module) 110 loaded on a vehicle including an engine 100 and an automatic transmission 200 and controlling fuel supply to the engine, differential rotational speed between an engine-side (input shaft) rotational speed detected by a drive rotational speed sensor 111 and a drive wheel 150 side (output shaft) rotational speed detected by an output rotational speed sensor 211 is calculated in releasing lock-up for integrally rotating the input shaft 201 and the output shaft 202 by a transmission mechanism 203 of the automatic transmission, and fuel cut is switched off (permitting restart of fuel supply) in a case when the differential rotational speed is a predetermined differential rotational speedΔr1 or more.</p> |
