摘要: A method and system for controlling a downshift for a hybrid vehicle includes: determining whether a running mode of the hybrid vehicle is an electric vehicle (EV) mode; determining whether a kick-down occurs when the hybrid vehicle is in the EV mode, wherein the kick-down requires a downshift; operating an engine and performing a shift-start (SS) when a downshift condition according to the kick-down is satisfied; determining whether a speed of the engine and a speed of a motor are synchronized before performing an actual shift-begin (SB); engaging an engine clutch when the speed of the engine and the speed of the motor are synchronized; and performing the actual SB when the engine clutch is engaged.
