Abstract:
A method of controlling a hybrid vehicle including an automatic transmission and a motor generator comprises a pre-gearshift control, a mid-gearshift control, and a post-gearshift control. It is possible to prevent abnormal operations and damage of an automatic transmission due to reverse rotation of the input shaft of the automatic transmission and achieve smooth and stable pre-stop gearshift, by appropriately controlling reverse torque exerted in the input shaft of the automatic transmission, when a vehicle equipped with a hybrid driving apparatus including the automatic transmission performs the pre-stop gearshift.
