Claim Text:
1. A system for controlling torque for a hybrid vehicle, comprising: a power source that includes an engine and a motor; an engine clutch provided between the engine and the motor; a driving information detector configured to detect a demand torque for driving; a traction controller configured to control an oil pressure supplied into a brake to prevent a wheel slip and configured to request torque reduction control from a vehicle controller when the wheel slip is detected; and a vehicle controller configured to control engagement of the engine clutch for driving in a hybrid electric vehicle (HEV) mode, wherein the vehicle controller determines torques of the engine and the motor to perform the torque reduction control according to the requested for torque reduction control from the traction controller, and when the request for the torque reduction control is released, the vehicle controller sets a gradient for torque restoration of the engine and motor and applies the gradient to follow the demand torque for driving, wherein the vehicle controller maintains continuity of output torques of the engine and the motor by applying the gradient to prevent a step of the output torques from occurring.
