<p>When the driver steps on an accelerator peal to a certain depth and practically keeps the accelerator pedal at the certain depth to maintain a substantially constant accelerator opening Acc, a target additional torque Ttag, a maximum reflection rate kmax, and an increment krt of a reflection rate k are set based on the accelerator opening Acc and a vehicle speed V (step S130) . The reflection rate k is gradually increased by the increment krt to the maximum reflection rate kmax after elapse of a preset time period since a start of decreasing a base torque demand Tbase affected by the accelerator opening Acc and the vehicle speed V (step S140). An object torque demand T* is computed as the sum of the base torque demand Tbase and an additional torque Tadd, which is given as the product of the target additional torque Ttag and the gradually increasing reflection rate k (steps S150, S180, and S190). The operations of an engine and two motors are then controlled with the setting of the object torque demand T* (steps S200 to S260).</p> |
