The present invention relates to a torque reduction control method for a hybrid vehicle to determine final engine torque and final motor torque in consideration of the system efficiency of a hybrid vehicle by performing torque reduction control and calculating torque reduction control in parallel by the requirement torque of a driver after reflecting a control torque value in accordance with torque control requirement to the requirement torque of a driver. According to an embodiment of the present invention, the torque reduction control method comprises the steps of calculating the requirement torque of a driver; determining whether there is a signal for torque control requirement; calculating the requirement torque of a driver where control torque is reflected when there is a signal for torque control requirement; calculating the operating points of a motor and an engine in consideration of hybrid system efficiency by the driver requirement torque where the control torque is reflected; calculating final engine torque and final motor torque from each operating point; and performing torque reduction, using the final engine torque and the final motor torque. |
