Vehicle remembrance sound generator and vehicle remembrance sound generation manner

摘要

Control section 740, it compares with the frequency characteristic of around sound of the vehicle MV which is obtained by the analysis with analytical section 730 and the frequency characteristic of the vehicle remembrance sound which is in the midst of outputting to external of vehicle MV. Continuation and control section 740 compares both frequency characteristics, it decides whether or not both frequency characteristics are similar mutually. When the result of particular decision is negative, as for control section 740, the corrugated specification in present time is maintained. As a result, of the vehicle remembrance sound which is in the midst of outputting at present time output continues to external. On the one hand, when the result of particular decision is affirmative, the new corrugated specification which specifies the ripple mark which does not resemble to the frequency characteristic of the analytical result is sent to supply section 750. As a result, generation of the output correspondence number which is based on the corrugated information which corresponds to new corrugated specification, is started in supply section 750, the vehicle remembrance sound which corresponds to new corrugated specification is output to external. As a result, appropriate vehicle remembrance sound, is output to external for note awakening to the pedestrian et. al.
