Problems solved by technology

However, it has been found that since the rotational axis of the DCT is restricted when performing preselection, power delivery performance and fuel efficiency are degraded due to drag loss
In other words, since shift responsiveness and fuel efficiency are in a trade-off, it's hard to achieve both

Abstract

A method and an apparatus for controlling a hybrid electric vehicle including a dual clutch transmission are provided. The method for controlling a hybrid electric vehicle including a dual clutch transmission may include: determining whether an engine start condition is satisfied in a state in which an engine is stopped; determining whether a kick-down shift condition is satisfied when the engine start condition is satisfied; connecting a speed gear corresponding to a target gear stage to an output shaft corresponding to the target gear stage when the kick-down shift condition is satisfied; determining whether a lock-up condition of an engine clutch is satisfied when the engine start condition is satisfied; locking up the engine clutch when the lock-up condition of the engine clutch is satisfied; and locking up a shift clutch corresponding to the target gear stage when the engine clutch is locked up.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2015-0176140 filed on December 10, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to apparatus and methods for controlling a hybrid electric vehicle. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Environmental technology for vehicles is very important, and the success or failure of the future automobile manufacturing industry depends on this technology. Vehicle manufacturers are striving to develop environmentally friendly vehicles to meet environmental and fuel consumption regulations. [0006] Some examples of applications of this future vehicle technology are hybrid electric vehicles (HEV) and dual clutch transmissions (D...
