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.
