NVH calibration has become one of the most critical approaches to range extender NVH control at the prototype vehicle stage. Calibration maximizes the NVH potential of the range extender: with engine speed and power as variables, multiple combinations of rotational speeds and power outputs are tested. Combined with measured in-cabin vibration and noise data, vehicle vibration and noise maps are generated. The optimal operating zones for the range extender are then selected by balancing NVH performance with other vehicle attributes — this constitutes the core task of range extender NVH calibration strategy.

Landtop Technology has provided range extender NVH matching and strategy solutions for many mainstream automakers, delivering superior range extender NVH performance on a host of best-selling vehicle models.
