ABSTRACT:
A vehicle having a sun gear, a carrier, and a ring gear of a planetary gear mechanism respectively connected to a first motor, an engine, and a drive shaft and second motor. When the combination of measured accelerator opening and measured vehicle speed is in an ordinary acceleration area, the vehicle sets a torque demand to decrease with an increase in measured vehicle speed at a specific reduction rate that ensures substantially constant output power to the drive shaft corresponding to the accelerator opening. When the combination of the measured accelerator opening and the measured vehicle speed is in an acceleration feel improvement area, on the other hand, the vehicle sets the torque demand to an extent of or below a maximum allowable value of the torque demand to decrease with an increase in measured vehicle speed at a lower reduction rate than the specific reduction rate.
