ABSTRACT:
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.
