SYSTEM AND METHOD FOR MOTOR-ASSISTED NON-UNIFORM DISPLACEMENT ENGINE CONTROL

A motor-assisted non-uniform displacement engine control system includes a non-uniform displacement engine comprising a plurality of cylinders, the cylinders comprising at least two kinds of cylinders having different displacements, a motor connected to a driving shaft of the engine, an energy storage device for supplying electrical energy to the motor, and a motor control unit for controlling the motor, wherein the motor control unit controls the motor to compensate for a difference in torque due to different displacements of the cylinders such that a sum of engine torque and motor torque during an explosion stroke of each cylinder is uniform.
