Abstract

A hybrid vehicle is provided. The hybrid vehicle includes an acceleration pedal, an engine configured to generate an engine torque based on a position of the acceleration pedal, an electronic control unit communicatively coupled to the engine and configured to calculate a target torque based on the position of the acceleration pedal, and estimate a motor-generated (MG)-assist torque based on difference between the target torque and the engine torque, a motor generator communicatively coupled to the electronic control unit and configured to generate the estimated MG-assist torque, and a power distribution unit configured to deliver the generated MG-assist torque combined with the engine torque to one or more wheels.
