Abstract
A hybrid vehicle comprises an internal combustion engine and a motor/generator, which are controlled by a microcomputer. The internal combustion engine is rendered capable of a running operation in a region of a better fuel consumption characteristic. Outside the above described region, the motor is cooperatively driven with the internal combustion engine to provide a driving torque or only the motor is energized by a battery to provide a driving torque. On the other hand, when the hybrid vehicle is driven with a torque smaller than a predetermined lower limit value of the torque of the internal combustion engine, the redundant torque is used to drive the generator, so that a regenerative power is absorbed by the battery.
