Abstract
A method of variably controlling a transmission pattern of a hybrid vehicle is provided. The method converts a transmission pattern into a pattern that sufficiently secures engine charge power by considering the total amount of electric load when the transmission pattern is determined based on a current SOC state. The method variably controls the transmission pattern of a hybrid vehicle to prevent a battery SOC excessive decrease due to an increase of electric load of a vehicle by reflecting and compensating for the used amount of electric load of a hybrid vehicle when the type of transmission pattern is determined. Also, fuel efficiency is improved based on the improvement of battery charge efficiency by determining the transmission pattern such that the speed of a transmission input terminal increases when the electric load increases and thus securing the engine charge power for the battery charge.
