ARTIFICIAL ENGINE SOUND CONTROL DEVICE, ARTIFICIAL ENGINE SOUND CONTROL SYSTEM USING THE SAME, MOVABLE BODY DEVICE, AND CONTROL METHOD OF ARTIFICIAL ENGINE SOUND

摘要

PROBLEM TO BE SOLVED: To provide an artificial engine sound control device which suppresses generation of unnatural artificial engine sound by adding traveling environments such as a road surface condition and weather.;SOLUTION: An artificial engine sound control device 3 includes a detection part 4a, a traveling environment determination part 4b, a control part 4c, and an adjustment part 5. The adjustment part 5 is arranged between an engine sound signal generation part 113 and an artificial engine sound source 104. The traveling environment determination part 4b estimates a traveling environment condition of a movable body device 51 based on a reference signal detected by the detection part 4a. The control part 4c generates a control signal for adjusting volume of artificial engine sound in response to an estimation result at the traveling environment determination part 4b, and outputs to the adjustment part 5. Thereby, the artificial engine sound depending on the traveling environment can be generated, and uncomfortable feeling a driver feels to the artificial engine sound while driving can be suppressed.;COPYRIGHT: (C)2015,JPO&INPIT
