Problems solved by technology

[0008] However, depending on the current operating state, the above control method takes some time to determine what type of engagement to use
As a result, the time it takes for the engine clutch to engage increases and undesired vibration occurs when transitioning engagement types (i.e., when the clutch is not engaged by synchronous methods)
Therefore, electric power and fuel are consumed unnecessarily, and fuel efficiency and SOC are not maintained

Embodiment Construction

[0019] 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 boats and watercraft of ships, aircraft, etc., and includes hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen vehicles, and other alternative fuel vehicles (eg, fuels derived from sources other than petroleum). As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, for example, a vehicle that has gasoline power and electric power.

[0020] The terminology used herein is for describing specific embodiments only and is not intended to limit the present invention. As used herein, the singular form "a, an, the" is also intended to include the plural forms unless the context clearly dictates otherwise. It should also be understood that t...

Abstract

Disclosed is a control method that improves response delay by reducing the time taken to determine the engagement type of an engine clutch, by making it possible to determine quickly the engagement type by a slip process under a disadvantageous operating conditions for the synchronization process such as traveling up a slope, traveling in a congestion section, or traveling under to or close to a discharging limit, and can improve fuel efficiency and battery SOC management due to unnecessarily using electric energy when engagement cannot be achieved by the synchronization process.

Description

[0001] Cross References to Related Applications [0002] This application is based on 35 U.S.C. §119(a) claiming the benefit of Korean Patent Application No. 10-2012-0120003 filed on October 26, 2012, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a control system and method for a hybrid vehicle, and more particularly, to a system and a system for controlling an engine clutch in a vehicle equipped with a parallel hybrid power train with a TMED (Transmission Mounted Electric Device) method. Background technique [0004] The TMED of the hybrid powertrain changes operating modes by engaging / disengaging an engine clutch disposed between an engine and an electric motor. In order to control the engine clutch, there are currently at least two types of methods available. One of the methods is the synchronous method, in which the speed and acceleration of the engine-motor are synchronized, and the hydrau...
