ABSTRACT:
In a hybrid vehicle where an engine, a first motor, and a driveshaft are all connected to a planetary gear mechanism and the driveshaft is further linked to a second motor, when a battery is in an unchargeable state in the release of both an accelerator and a brake (step S130), a throttle opening TH* and a valve timing VVT* for air intake and exhaust are set to increase a pumping loss of the engine with an increase in absolute value of a braking power demand, which is to be output to the driveshaft (step S170). The engine is controlled with the throttle opening TH* and the valve timing VVT*, while the second motor is under regenerative control to generate electric power. The first motor used for motoring of the engine is then controlled to consume the electric power generated by the regenerative control of the second motor.
