Abstract
A power output unit of the present invention sufficiently ensures the performance of a vehicle by sufficiently developing the performance of an engine without enlarging a motor. In a hybrid vehicle, a power requirement for the engine is set based on a vehicle speed and an accelerator opening degree. Usually, while giving priority to efficiency, an operation state of the engine is set based on a power requirement. Once the operation state of the engine is set, operation states of first and second motors are set based on a vehicle speed and a drive force. If the thus-set operation state of the first or second motor exceeds a threshold value, the operation state of the first or second motor is set so as not to exceed the threshold value. Based on the setting result and the power requirement, an operation state of the engine is set.
