PROBLEM TO BE SOLVED: To control generation of an abnormal noise in a mechanical mechanism to which a motors is connected.SOLUTION: When a torque Trtmp for traveling is larger than a threshold value Tref, and when a behavior stable condition flag F is a value 0, the torque Trtmp for traveling is set to a requested torque Tr* (S120), and an engine and two motors are controlled so that the requested torque Tr* is output to the drive shaft, while the engine is driven by a drive point of lower rotation speed and higher torque side than a fuel consumption drive point responding to the request power Pe* based on the requested torque Tr* and a fuel consumption operation line (S140-S180, S200-S240). Meanwhile, when a behavior stable condition flag F is a value 1, the torque that is smaller than the torque Trtmp for traveling is set to the requested torque Tr* (S130), an engine and two motors are controlled so that the requested torque Tr* is output to the drive shaft, while the engine is being driven at the fuel consumption drive point (S140-S160, S190-S240). |
