A generation control system for a vehicle includes an ac generator, a field current control unit that controls the duty ratio of field current of the ac generator, a field current detector, a load current detector, a generator rotation speed detector, a driving-torque-increase calculator that calculates a predicted increase in driving torque of the ac generator from increase in the current supplied to an electric load. The driving-torque-increase calculator includes first output current calculator that calculates present output current of the ac generator from the generator's rotation speed and the field current and second output current calculator that calculates predicted output current of the ac generator from the first output current and the increase in the current supplied to the electric load. A predicted increase in driving torque of the ac generator is calculated from a difference between the present driving torque and a driving torque that corresponds to the predicted output current.
