Apparatus and method for controlling clutch slip of hybrid vehicle

A method for controlling a clutch slip of a hybrid vehicle including a motor selectively connected to an engine through an engine clutch and a transmission selectively connected to the motor through a dual clutch mechanism having two clutches, the method comprising:

• receiving a transfer torque of the dual clutch mechanism;
• calculating a motor speed from the transfer torque of the dual clutch mechanism;
• determining a transfer torque of the engine clutch;
• calculating an engine speed from the transfer torque of the engine clutch;
• and
• simultaneously performing a slip control of the dual clutch mechanism according to the calculated motor speed and a slip control of the engine clutch according to the calculated engine speed.

A non-transitory computer readable medium containing program instructions executed by a processor on a controller, the computer readable medium comprising:

• program instructions that receive a transfer torque of a dual clutch mechanism;
• program instructions that calculate a motor speed from the transfer torque of the dual clutch mechanism;
• program instructions that determine a transfer torque of an engine clutch;
• program instructions that calculate an engine speed from the transfer torque of the engine clutch;
• and
• program instructions that simultaneously perform a slip control of the dual clutch mechanism according to the calculated motor speed and a slip control of the engine clutch according to the calculated engine speed.
