A hybrid vehicle is capable of performing regenerative operations of
generator-motors disposed adjacently to front wheels and/or rear wheels
of the vehicle so as to achieve efficient conversion of kinetic energy of
the vehicle into electric energy as much as possible when the vehicle
slows down, thereby permitting higher use efficiency of energy. When the
vehicle decelerates, a target deceleration force or a target deceleration
torque of the vehicle is set, and a permissible maximum value of the
braking torque to be imparted to rear wheels from a second
generator-motor is set, and the permissible maximum value and the target
deceleration torque of the vehicle, whichever is smaller, is set as a
target braking torque to be imparted from the second generator-motor to
the rear wheels. Furthermore, with the remaining torque of the target
deceleration torque being set as an upper limit, a target braking torque
to be imparted to front wheels from a first generator-motor is
determined, and a friction type braking mechanism compensates a shortfall
torque of a total sum of the target braking torques of the two
generator-motors to reach the target deceleration torque.
