The present invention addresses the problem of suppressing an excessive decrease in the output torque of an engine during execution of an inter-cylinder correction process. A drive control device is applied to a vehicle provided with a spark ignition engine having a plurality of cylinders. A first processing circuit of the drive control device executes inter-cylinder correction processing for correcting fluctuations in the magnitude of engine torque at the ignition timing of a plurality of cylinders and adjusting the amount of fuel supplied to the cylinders or the ignition timing for each of the plurality of cylinders. Lower limit protection is set for the amount of fuel supplied to the cylinder or the correction amount of ignition timing when the inter-cylinder correction process is executed.
