DRIVE SOURCE CONTROL DEVICE FOR VEHICLE

摘要

An object of the present invention is to provide a driving source control apparatus for hybrid vehicle capable of lowering an amount of fuel consumption and an amount of exhaust gas without deteriorating necessary acceleration performance. The driving source control apparatus includes means for calculating additional torque to be outputted from the motor according to accelerator opening and vehicle speed by assuming that there is no additional torque from the engine when an acceleration request is made by an accelerator operation, and means for setting shortage as an additional torque from the engine when the calculated additional torque from the motor causes a shortage of torque. Further, the apparatus restrains shift transmission and calculates additional torque corresponding to kickdown shift transmission by using a transmission gear ratio when the acceleration request fulfills predetermined kickdown requirements.
