2. A catalyst heating control method for a parallel hybrid vehicle, comprising the steps of:
-
determining a target catalyst heating ignition efficiency; calculating a catalyst heating engine torque; calculating a no-load operation requirement torque of the engine to maintain a stable no-load operation state of the engine; determining a motor compensation requirement torque; and controlling a motor using the motor compensation requirement torque to maintain the stable no-load operation state of the engine by supplementing the torque of the engine operated with the target catalyst heating ignition efficiency. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 17)
