Title:
A SIMULATED ENGINE SOUND GENERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/132347
Kind Code:
A1
Abstract:
This invention related to a simulated engine sound generating apparatus 200 for use in an electric vehicle which reproduces a simulated engine sound predicted from modified waveform data of an actual engine sound according to a vehicle speed on the basis of a motor rotation number of the electric vehicle and generates the simulated engine sound, including: vehicle speed detection means 210,first storage means 221, second storage means 222, memory controller 224 for deciding the sampling cycle corresponding the vehicle speed, mixer 226 which receives the basic sound pressure waveform from the second storage means 222and amplifies the basic sound pressure waveform according to the vehicle speed transmitted from the second storage means 222 at a programmed ratio and sound generation means 230 as shown Fig.1.
