Abstract
A vehicle can ensure an engine torque the driver desires even though the load torque of a generator with respect to the engine varies, and in particular can restrain occurrence of such a risk that an engine stall occurs when a load to the engine is large upon, for example, engagement of a clutch. A controller predicts a load torque of the generator with respect to the engine in future several hundred milliseconds at maximum from the present time, in view of a magnetic field voltage and a speed of the generator at the present time, and controls the engine in accordance with the predicted load torque in order to prevent the output torque of the engine from being insufficient.
