Abstract

The invention relates to a hybrid electric vehicle (HEV) and a method of controlling a shift pattern therefor. The method comprises following steps: determining whether or not a request for shift pattern change is received, determining whether HEV mode related conditions are satisfied or not, in response to a determination that the request for shift pattern change is received, and changing a shiftpattern according to the request for shift pattern change, in response to a determination that the HEV mode related conditions are satisfied.

Description

technical field [0001] The invention relates to a hybrid electric vehicle and a control method for its shift mode, and more particularly to a hybrid electric vehicle capable of effectively determining the time point at which the shift mode changes and a control method for the hybrid electric vehicle and its shift mode. Background technique [0002] Generally, a hybrid electric vehicle (HEV) is a vehicle using two power sources, and the two power sources are mainly an engine and an electric motor. Such hybrid electric vehicles have been flourishing due to their superior fuel efficiency and power performance compared to vehicles with only internal combustion engines, and are beneficial for reducing exhaust emissions. [0003] Hybrid electric vehicles can operate in two driving modes, depending on the type of powertrain being driven. One is an electric vehicle (EV) mode in which a hybrid electric vehicle is driven using only a motor, and the other is a hybrid electric vehicle ...
