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.

The invention claimed is: 1. A vehicle comprising an internal combustion engine incorporated therein, a plurality of drive mechanisms, a generator having a magnetic field current that is changeable by adjustment of a magnetic field voltage to modify output electric power and generator load torque, said generator driven by the internal combustion engine, and an electric motor for driving vehicle wheels, whereinsaid drive mechanisms are configured to be controlled based on a field voltage of said generator and rotating speeds of said generator and of said electric motor, andif the load torque of said generator varies, a peak value of wave height with respect to a time axis of a waveform, indicating variation of operation of the drive mechanisms, occurs earlier than a peak value of wave height with respect to a time axis of a waveform, indicating variation of the load torque of the generator.
