PROBLEM TO BE SOLVED: To prevent shortage of torque (power) output to a driving shaft, and to improve efficiency of energy of a vehicle.SOLUTION: When an abnormal noise condition in which torque output from a second motor becomes within a predetermined range including a value of zero and when the established condition does not continue over a predetermined time (S220, S230) if normal control is executed, for controlling an engine and two motors so that required torque Tr* is output to a driving shaft while operating the engine at an operation point on a fuel efficiency operation line, the control is performed so that the required torque Tr* is output to the driving shaft while operating the engine at an operation point on an abnormal noise prevention operation line (S240-S260). In contrast, when the established abnormal noise condition continues over the predetermined time, the control is performed so that the required torque Tr* is output to the driving shaft while stopping the operation of the engine (S270, S140-S160, S280, S300-S340). |
