ABSTRACT:
A drive control apparatus for a series hybrid vehicle. The series hybrid vehicle includes an engine, a generator, a battery and a motor. The generator is activated by electricity from the engine so as to drive the motor. The battery is charged by the electricity from the generator, being discharged so as to provide a voltage to the motor. In other words, the motor is also activated by discharging electricity from the battery. There are three modes for activating the motor, i.e. a mode for activating the motor only by the battery, a mode for activating it only by the generator, and a mode for activating it both by the battery and the generator. The motor activating modes will be selected depending upon a required motor output. An output voltage of the generator is determined so as to derive the required output according to the selected mode. The generator is of a type which can output a voltage according to a field current. The field current of the generator is controlled so as to obtain the required output voltage.
