Torque control of an electrical motor 4 connected to a drive shaft 6 and control of the rotation speed of a generator 2 supplying electrical power to the electrical motor 4 are performed in response to the running conditions of a vehicle. The actual generator output of the generator 2 is estimated at a given time and the drive output of the electrical motor 4 is limited in response to the estimated generator output. The drive output of the electrical motor 4 is limited in response to increases in consumed energy and reductions in the generated output of the generator 2 resulting from increases in the kinetic energy of rotating components of the engine 1 or the generator 2 during acceleration. Thus the difference of the generated output of the generator 2 and the consumed electrical power of the electrical motor 4 can be reduced during acceleration and it is possible to reduce the capacity of the battery supplying auxiliary electrical power.
