Abstract

The application relates to a hybrid vehicle and a control of controlling mode transition. The method controls the mode transition so as to predict a driver demanding torque, thus reducing non-driven fuel losses; the hybrid vehicle performing said method is also provided. In particular, the method of controlling the mode transition of the hybrid vehicle may include: determining whether to change afirst mode to a second mode based on a first torque; determining a second torque expected to be generated at a near-future time after a current time; determining whether or not an engine clutch engagement is possible at the near-future time based on the second torque or a predicted acceleration; and performing the change from the first mode to the second mode when the mode change from the first mode to the second mode is determined and the engine clutch engagement is possible.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0172825 filed on December 16, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a hybrid vehicle and a method of controlling a control mode transition to reduce fuel loss. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Demand for environmentally friendly vehicles is increasing due to the continuous demand for improvements in fuel efficiency of vehicles and the strengthening of exhaust regulations in many countries. As a practical alternative to environmentally friendly vehicles, hybrid electric vehicles / plug-in hybrid electric vehicles (HEV / PHEV) are offered. [0006] The hybrid vehicle can provide optimum output and torque...
