Drive control device

Abstract

To prevent the engine's output torque from dropping too much during the execution of inter-cylinder correction processing. [Solution] The drive control device 300 is applied to a vehicle 10 equipped with a spark-ignition engine 20 having multiple cylinders 22. The first processing circuit 311 of the drive control device 300 performs inter-cylinder correction processing to adjust the amount of fuel supplied to each cylinder 22 or the ignition timing for each of the multiple cylinders 22 in order to correct for variations in the magnitude of engine torque at the ignition timing of the multiple cylinders 22. A lower limit guard is set for the amount of correction of the amount of fuel supplied to each cylinder 22 or the ignition timing when the inter-cylinder correction processing is performed.
