Abstract
In a parallel hybrid vehicle, an revolution speed of an engine, a revolution speed of a motor/generator, and a regenerative power obtained by the motor/generator are calculated under both of released and clutched states of a lock-up clutch for each gear speed range achievable by a transmission on the basis of an estimated requested vehicular deceleration state and a driving state related to one of the gear speed ranges of the transmission and an operation state of the clutch is selected on the basis of the engine speed of the engine, the revolution speed of the motor/generator, and a regenerative power obtained by the motor/generator calculated as described above in such a manner that as a charge state of the charge device becomes smaller, the regenerative power obtained by means of the motor/generator becomes larger.
