Abstract
A torque monitoring system and method of a hybrid electric vehicle is provided that accurately monitors and diagnoses a compensation torque, such as an intervention torque generated from the vehicle's perspective and an engine friction torque, in addition to a driver's request torque. The torque monitoring system includes a control unit configured to: determine final command torques for respective power sources; determine a requested torque for monitoring based on vehicle driving information; determine compensation torques for the respective power sources depending on whether an engine clutch is engaged based on intervention torques for the respective power sources and additional torques for the respective power sources; determine a command torque limit value; and determine whether there is an abnormality in each torque determination process based on the determined command torque limit value and a sum of the determined final command torques for the respective power sources.
