Abstract

The invention relates to a control system and method for an engine clutch. The method for controlling an engine clutch includes steps of controlling the hydraulic pressure transmitted from a master cylinder, driven by a motor, to a concentric slave cylinder using a controller outputting a motor control command for controlling an engine clutch so as to switch the engine clutch to a target state, driving the engine clutch using the concentric slave cylinder, after the step of controlling hydraulic pressure, detecting a position of a piston of the master cylinder using a first travel sensor and detecting a position of a piston of the concentric slave cylinder using a second travel sensor, and performing compensation control with respect to the motor based on the positions of the pistons detected by the first travel sensor and the second travel sensor using the controller so that the engine clutch is switched to the target state.

Description

technical field [0001] The present disclosure relates to a system and method for controlling an engine clutch. More particularly, the present invention relates to a system and method for controlling an engine clutch of a hybrid electric vehicle that moves the engine clutch to a precise position by compensating for volume changes in working fluid due to temperature changes. Background technique [0002] A hybrid electric vehicle (HEV) refers to a vehicle that uses two or more different power sources. Generally, an HEV is driven by an engine that generates driving power by burning fuel and an electric motor that generates driving power using electric energy from a battery. [0003] figure 1 is a schematic diagram of a powertrain of an HEV, particularly a transmission-mounted electric device (TMED) type powertrain in which a drive motor 3 and a transmission 4 are directly connected to each other. [0004] As shown in the figure, in the TMED power transmission system, a trans...
