Abstract
A type of driving controller for a vehicle that makes use of a combination of a generator and an AC motor to perform stable motor torque control. Target output electric power that should be output from the generator is computed on the basis of the motor's necessary electric power, and the generator is controlled at the operating point where the torque instruction value computed on the basis of the target output electric power can be generated at good efficiency. Also, the torque instruction value of the motor is computed on the basis of present output voltage and output current of the generator, and the motor is controlled on the basis of the torque instruction value.
