Abstract

The present invention relates to an environmentally-friendly vehicle sound generator apparatus and a control method thereof, and the apparatus comprises: 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.

Description

technical field [0001] The present invention relates to an eco-friendly vehicle sound generator device and a control method thereof. More specifically, the present invention relates to an eco-friendly vehicle sound generator device and a control method thereof, which sense various operating states of a vehicle and play various types of sounds according to the sensed operating states of the vehicle or in different playing methods. Operation sound so that virtual sound (i.e., operation sound) close to the real engine sound according to the vehicle operation state can be generated and output to be transmitted to the driver or pedestrians, thereby further ensuring the safety of pedestrians and realizing safe driving of the driver . Background technique [0002] In recent years, due to the consumption of energy, the development of eco-friendly vehicles as an alternative means of transportation has increasingly been actively progressing. Examples of representative eco-friendly v...
