Abstract
In a state of reverse driving with load operation of an engine, an upper limit torque Temax of the engine is set to cause a total torque of a torque demand Tr* and a cancellation torque for cancelling a torque applied to a driveshaft accompanied with load operation of the engine to be output from a second motor to the driveshaft. A product of the upper limit torque Temax of the engine and an upper limit rotation speed Nemax of the engine is set to an upper limit power Pemax. A target power Pe* of the engine is then set in a range of not greater than the upper limit power Pemax. The engine, a first motor and the second motor are then controlled such as to cause the target power Pe* to be output from the engine and such as to output the torque demand Tr* to the driveshaft.
