ENVIONMENTALLY-FRIENDLY VEHICLE OPERATING SOUND GENERATOR APPARATUS AND METHOD FOR CONTROLLING THE SAME

摘要

A method for controlling an environmentally-friendly vehicle operating sound generator apparatus. The method includes a step of providing an environmentally-friendly vehicle operating sound generator apparatus. The method further includes a diagnosis confirmation step of allowing the control unit to confirm a connection state of the sound output unit and an operation state of the sound source playback unit and compare an output of the sound source amplification unit with a preset reference value to diagnose the presence of distortion. The method further includes an operating sound execution step of allowing the control unit to determine whether or not to generate an operating sound of the environmentally-friendly vehicle according to the vehicle operation state sensed by the vehicle state sensing unit, output at least one sound source, selected from among the sound sources stored in the sound source storage unit, as the operating sound through the sound output unit.

1. A method for controlling an environmentally-friendly vehicle operating sound generator apparatus, the method comprising:
a providing step of providing the environmentally-friendly vehicle operating sound generator apparatus comprising a vehicle state sensing unit for sensing an operation state of a vehicle, a sound source storage unit for storing a plurality of operating sounds that can be output according to the operation state of the vehicle in the form of a sound source data, a sound source playback unit for selecting at least one of the operating sounds stored in the sound source storage unit and playing back the selected sound source output from the sound source storage unit, a sound source amplification unit for amplifying the operating sound played back by the sound source playback unit, a sound output unit for outputting the operating sound amplified by the sound source amplification unit, and a control unit for receiving a sensing signal from the vehicle state sensing unit and controlling the operation of the sound source playback unit so as to play back the operating sound in different playback methods in such a manner as to control and change the operating sound according to the received sensing signal; an initialization step of comprising a diagnosis confirmation step (S30) of allowing the control unit to confirm a connection state of the sound output unit and an operation state of the sound source playback unit and compare an output of the sound source amplification unit with a preset reference value to diagnose the presence of distortion; and an operating sound execution step of allowing the control unit to determine whether or not to generate an operating sound of the environmentally-friendly vehicle according to the vehicle operation state sensed by the vehicle state sensing unit, output at least one sound source, selected from among the sound sources stored in the sound source storage unit, as the operating sound through the sound output unit.
