A drive control apparatus includes a circuitry configured to operate a differential lock device of a differential device in timings which are different between a two wheel drive state and a four wheel drive state. The differential device is disposed between one of a pair of front wheels and a pair of rear wheels of the vehicle and configured to transmit a driving force from a drive source to the one of the pair of front wheels and the pair of rear wheels. The differential lock device is configured to lock a differential rotation of a pair of output members of the differential device that are differentially rotatable with respect to each other, and configured to respectively output the drive force.
