Abstract
A controller (10, 11, 12) computes a virtual generated power, this being the power generated by a generator (2) when an engine (1) and the generator (2) are controlled so that the power generated by the generator (2) coincides with the power consumption of a motor (4) which is uniquely determined according to a vehicle running state, computes an output limiting value of the motor (4) based on the virtual generated power, and limits the power or torque of the motor (4) by the output limiting value.
