An automatic transmission controller for a hybrid vehicle of the present
invention is used for the hybrid vehicle being a four-wheel drive vehicle
and including an engine and a generator motor on a front wheel side of
the hybrid vehicle and a traction motor on a rear wheel side of the
hybrid vehicle. The automatic transmission controller for a hybrid
vehicle includes: an automatic transmission for transmitting a driving
force from the engine to an output shaft of the hybrid vehicle; and an
oil pump for supplying a speed-shifting clutch of the automatic
transmission with pre-pressure to eliminate play of the speed-shifting
clutch, when the hybrid vehicle is driven by a driving force from the
traction motor.
