A Warning Sound Is Mandatory For Electric Vehicles<\/strong><\/p>\n

Dal 1\u00b0 luglio 2019 \u00e8 obbligatorio installare un generatore di suoni di avvertimento nelle auto elettriche. Ci\u00f2 \u00e8 dovuto a una nuova direttiva dell'UE. Questa stabilisce che inizialmente nei veicoli ibridi, elettrici e a celle a combustibile di nuova omologazione \u2013 cos\u00ec come in camion e autobus \u2013 debba essere installato il sistema acustico di avviso del veicolo (AVAS) per la protezione degli altri utenti della strada. Nell'UE l'avviso acustico \u00e8 obbligatorio fino a una velocit\u00e0 di 20 km\/h. La direttiva formula in dettaglio i parametri relativi a come un avviso AVAS pu\u00f2 e non pu\u00f2 suonare. Ci\u00f2 vale, ad esempio, per il volume sonoro minimo e massimo e per alcune componenti sonore.<\/p>\n

\u00c8 nel rispetto di queste e di molte altre normative che gli esperti del suono del centro prove acustiche del Mercedes-Benz Technology Centre (MTC) di Sindelfingen lavorano per dare una voce alle Mercedes elettrificate.<\/p>\n

Speciali microfoni presenti nelle strutture di prova del suono esterno vengono utilizzati per sviluppare un e-sound configurato individualmente per ogni modello elettrico. Simulazioni, misurazioni, valutazioni e miglioramenti dettagliati continuano fino a quando il risultato non \u00e8 perfetto. Durante i successivi test su strada, a bordo \u00e8 presente un passeggero particolarmente sensibile: la testa artificiale. Questa registra i minimi rumori e si avvicina in modo impressionante all'udito umano.<\/p>\n

Standard differenti in mercati diversi<\/strong><\/p>\n

Il suono AVAS della Mercedes-Benz differisce solo leggermente per l'UE, il Giappone e la Cina. Per gli Stati Uniti esistono altri requisiti, ad esempio per quanto riguarda il volume del suono. Inoltre, il veicolo fermo deve gi\u00e0 generare un suono quando viene inserita una marcia, diventando pi\u00f9 forte fino a 30 km\/h. La disattivazione dell'AVAS da parte del cliente \u00e8 vietata in quasi tutti i paesi.<\/p>\n
