Title:
A sound effect generator for vehicles
Document Type and Number:
Japanese Patent JP6222578
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sound effect generator for vehicles, capable of optimizing a driving procedure of a driver in accordance with traveling condition, and improving driving skill of the driver.SOLUTION: A sound effect generator 1 for vehicles includes: a travel state determination unit 11; a perceived optical flow detection unit 12 configured to detect a perceived optical flow G1 visually recognizable by a driver; an estimated optical flow detection unit 13 configured to detect an estimated optical flow G2 that is estimated to be taking place according to traveling condition; a comparator 15 that compares the perceived optical flow G1 and the estimated optical flow G2; a pair of left and right speakers 8a, 8b; and a sound effect generation unit 16 capable of adjusting sound pressure levels of the speakers 8a, 8b, where the sound effect generation unit 16 is configured to control the sound pressure levels of the speakers 8a, 8b such that a difference ΔG between the perceived optical flow G1 and the estimated optical flow G2 is eliminated.SELECTED DRAWING: Figure 2
