Problems solved by technology

However, to transition from EV mode to HEV mode when the motor is engaged with the DCT, the engagement force of the DCT is reduced to create slip of the DCT and the linearity of the acceleration (eg, the acceleration is linearly adjusted) may be reduced
Also, the linearity of acceleration may drop even more when the motor and engine are synchronized and the wheel torque is reduced

Embodiment Construction

[0021] It should be understood that the term "vehicle" or "vehicular" or other similar terms as used herein includes motor vehicles in general, for example, passenger vehicles including sport utility vehicles (SUVs), buses, trucks, commercial vehicles of all kinds, including various Ships and marine craft, aircraft, etc., and include hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen vehicles, and other alternative fuel vehicles (eg, fuels derived from sources other than petroleum). A hybrid vehicle, as referred to in this article, is a vehicle that has two or more sources of power, such as a vehicle that is both gasoline-powered and electric-powered.

[0022] Although the exemplary embodiment has been described as using multiple units to perform the exemplary process, it is understood that the exemplary process may also be performed by one or more modules. Additionally, it should be understood that the term controller / control unit refers to a hardw...

Abstract

An apparatus and method for controlling a clutch of a hybrid vehicle are provided. The method includes: setting, by a controller, a limited torque to a motor torque and comparing an input speed of the transmission and a minimum speed of the engine when converting from an EV driving mode to an HEV driving mode. The controller is configured to start the engine when the input speed of the transmission is equal to or greater than a minimum threshold point and is equal to or less than a minimum speed of the engine. Further, the method includes increasing the motor torque to exceed the preset limited torque, coupling the first clutch when the engine speed and a motor speed are synchronized, and coupling the second clutch when the input speed of the transmission exceeds the minimum speed of the engine by the controller.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefits from Korean Patent Application No. 10-2014-0067185 filed on June 2, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an apparatus and method for controlling a clutch in a hybrid vehicle, and more particularly, the present invention relates to an apparatus and method for controlling a clutch in a hybrid vehicle when a hybrid with a dual clutch transmission (DCT) is installed When the drive mode of a powered vehicle is changed from an electric vehicle (EV) drive mode to a hybrid vehicle (HEV) drive mode, set the limit torque for the motor torque and use the slip transition of the dual clutch transmission (DCT) to change the hybrid vehicle mode . Background technique [0004] A hybrid vehicle is a vehicle that uses two or more different types of power sources. Generally, a hybrid vehicle is dr...
