System and method for controlling torque of hybrid vehicle

Abstract

A system for controlling torque controls torque during traction control of a hybrid vehicle which uses a motor and an engine as power sources. The system for controlling torque may include: a traction control system (TCS) that detects wheel slip of a front wheel or a rear wheel when the hybrid vehicle is accelerated and requests an intervention torque; a battery sensor that measures state of charge (SOC) in real time; and a vehicle controller that determines a set value of a limit torque according to the SOC transmitted from the battery sensor when requesting the intervention torque and decreases a motor torque according to the set value of the limit torque when the SOC is lower than a predetermined threshold, and then increases an engine torque by as much as the motor torque is decreased.
