PROBLEM TO BE SOLVED: To provide a drive torque control device that has high energy efficiency, can achieve smooth drive torque control matching with the behavior of a vehicle and is applicable to a vehicle, and to provide a driving source unit and a vehicle.SOLUTION: A drive torque control device comprises a target drive wheel torque calculation part calculating a target drive wheel torque of drive wheels of a vehicle, a driving source torque control part controlling the driving source torque produced with the driving force of a driving source transmitted to the drive wheels, and a braking torque control part controlling at least the braking torque produced by a brake mechanism of the drive wheels. The driving source torque control part calculates a target driving source torque to be used for control of the driving source torque on the basis of the target drive wheel torque and a driving source torque limit value, and controls the driving source torque on the basis of the target driving source torque. The braking torque control part calculates a target braking torque on the basis of the target drive wheel torque, the target driving source torque and a braking torque limit value, and controls the braking torque on the basis of the target braking torque.SELECTED DRAWING: Figure 4
