Une \u00e9tude r\u00e9cente men\u00e9e par l'institut belge de s\u00e9curit\u00e9 routi\u00e8re Vias montre que les v\u00e9hicules \u00e9lectriques sont\u00a0sont plus souvent impliqu\u00e9s dans des accidents impliquant des usagers vuln\u00e9rables de la route.\u00a0<\/span>Ils sont impliqu\u00e9s dans 42% d'accidents ayant caus\u00e9 des blessures et impliquant des voitures \u00e9lectriques, contre 27% pour l'ensemble des types de v\u00e9hicules.<\/span><\/p>\n

Vias a cherch\u00e9 \u00e0 d\u00e9terminer si les niveaux sonores plus faibles des v\u00e9hicules \u00e9lectriques et hybrides pouvaient avoir une incidence sur la s\u00e9curit\u00e9 des usagers vuln\u00e9rables de la route. Une attention particuli\u00e8re a \u00e9t\u00e9 accord\u00e9e aux personnes malvoyantes, qui sont les plus touch\u00e9es par l'absence de bruit.<\/span><\/p>\n

Une explication possible \u2013 bien que ce ne soit pas n\u00e9cessairement la cause \u2013 est le silence des v\u00e9hicules \u00e9lectriques. Surtout \u00e0 \u00c0 faible vitesse, les mod\u00e8les \u00e9lectriques font moins de bruit, sont rep\u00e9r\u00e9s plus tardivement et sont plus difficiles \u00e0 localiser que les v\u00e9hicules \u00e9quip\u00e9s de moteurs \u00e0 combustion interne.\u00a0<\/span>Vias pr\u00e9conise de relever la norme minimale en mati\u00e8re de bruit et d'harmoniser les normes entre les diff\u00e9rentes marques.<\/span><\/p>\n

Cadre juridique<\/h4>\n

Pour rem\u00e9dier au probl\u00e8me du silence des v\u00e9hicules \u00e9lectriques, l'Union europ\u00e9enne a mis en place le \u2018 syst\u00e8me d'alerte acoustique des v\u00e9hicules \u2019 (AVAS) pour toutes les voitures \u00e9lectriques. Il s'agit d'un son artificiel que tous les v\u00e9hicules \u00e9lectriques doivent \u00e9mettre. <\/span>En d'autres termes, la loi impose aux voitures \u00e9lectriques d'\u00e9mettre un son sp\u00e9cifique lorsqu'elles roulent \u00e0 faible vitesse. <\/span><\/p>\n

Cependant,\u00a0<\/span>son efficacit\u00e9 est parfois remise en question. R\u00e9cemment,\u00a0<\/span>Une \u00e9tude men\u00e9e par Vias a montr\u00e9 que ce signal sonore n'est souvent pas assez fort et qu'il varie en outre d'une marque \u00e0 l'autre. <\/span>L'institut estime que cela doit changer, <\/span>d'autant plus que le nombre de v\u00e9hicules \u00e9lectriques ne cesse d'augmenter.\u00a0<\/span>Au cours des cinq derni\u00e8res ann\u00e9es, la part des voitures \u00e9lectriques ou hybrides dans notre pays est pass\u00e9e de 3% \u00e0 20%.<\/span><\/p>\n

Mesures du bruit<\/h4>\n

Au cours de l'\u00e9tude, diverses mesures de bruit ont \u00e9t\u00e9 effectu\u00e9es sur un circuit ferm\u00e9 \u00e0 l'aide de cinq v\u00e9hicules (trois \u00e9quip\u00e9s de moteurs \u00e0 combustion interne et deux \u00e9lectriques) effectuant diff\u00e9rentes man\u0153uvres (conduite \u00e0 vitesse constante, d\u00e9c\u00e9l\u00e9ration, acc\u00e9l\u00e9ration et marche arri\u00e8re).<\/span><\/p>\n

De plus, Vias a fait participer 70 personnes, dont la moiti\u00e9 \u00e9taient aveugles ou malvoyantes, qui ont \u00e9cout\u00e9 des enregistrements de voitures ICE, \u00e9lectriques et hybrides dans diff\u00e9rents niveaux de bruit de fond. Le pourcentage de voitures que les participants n\u2019ont pas r\u00e9ussi \u00e0 d\u00e9tecter \u00e9tait le suivant :<\/p>\n

\"\"<\/p>\n

Les r\u00e9sultats montrent qu'\u00e0 une vitesse de 10 km\/h, tous les moteurs \u00e0 combustion interne produisent un niveau sonore comparable (environ 55 dB), tandis que les voitures \u00e9lectriques \u00e9quip\u00e9es d'un syst\u00e8me AVAS actif pr\u00e9sentent des diff\u00e9rences les unes par rapport aux autres.\u00a0<\/span><\/p>\n

\u00c0 10 km\/h, les voitures hybrides et \u00e9lectriques passent plus souvent inaper\u00e7ues que les voitures \u00e9quip\u00e9es d'un moteur \u00e0 combustion interne. <\/span>\u00c0 20 km\/h, 18% de v\u00e9hicules hybrides ne sont pas d\u00e9tect\u00e9s, contre 11% pour les voitures \u00e0 moteur \u00e0 combustion interne et 7% pour les voitures \u00e9lectriques.<\/span><\/p>\n

De mani\u00e8re g\u00e9n\u00e9rale, les personnes aveugles ou malvoyantes ont eu un peu plus de mal que le groupe t\u00e9moin \u00e0 rep\u00e9rer les voitures lorsque le bruit de fond \u00e9tait faible.\u00a0<\/span>\u00c0 faible vitesse, les usagers vuln\u00e9rables de la route ne remarquent pas toujours les voitures \u00e0 temps. C'est particuli\u00e8rement vrai pour les personnes aveugles et malvoyantes.<\/span><\/p>\n

La conception sonore est importante<\/h4>\n

Dans cette \u00e9tude, Vias a d\u00e9montr\u00e9 que la conception sonore jouait un r\u00f4le important et recommande donc d\u2019am\u00e9liorer le syst\u00e8me \u00e0 plusieurs \u00e9gards : normaliser le son utilis\u00e9, relever le seuil sonore minimal (dans des limites raisonnables afin d\u2019\u00e9viter les nuisances sonores) et privil\u00e9gier les fr\u00e9quences qui contribuent le plus efficacement \u00e0 am\u00e9liorer la d\u00e9tectabilit\u00e9 des v\u00e9hicules \u00e9lectriques.<\/span><\/p>\n

Une remarque \u00e0 propos de cette \u00e9tude, toutefois : les v\u00e9hicules \u00e9lectriques ne sont jamais vraiment totalement silencieux lorsqu'ils roulent.\u00a0<\/span>Apr\u00e8s tout, il y a toujours le bruit des pneus \u2013 l'interaction pneu\/route \u2013, ainsi que celui des roulements, celui de la transmission et, enfin, le bruit a\u00e9rodynamique.<\/span><\/p>\n

Autres bruits provenant du v\u00e9hicule<\/h4>\n

Des \u00e9tudes sur le bruit des v\u00e9hicules ont m\u00eame montr\u00e9 que le bruit de roulement des pneus peut constituer la composante la plus importante jusqu'\u00e0 environ 20 km\/h, en fonction notamment du type de pneu, du rev\u00eatement routier et du v\u00e9hicule.<\/p>\n

L'institut n\u00e9erlandais SWOV (Institut national de recherche scientifique sur la s\u00e9curit\u00e9 routi\u00e8re) <\/span>avait d\u00e9j\u00e0 soulev\u00e9 ce point il y a plusieurs ann\u00e9es : sur les routes n\u00e9erlandaises limit\u00e9es \u00e0 30 km\/h, dont le rev\u00eatement est irr\u00e9gulier ou pav\u00e9 de klinkers, le bruit de roulement des pneus peut prendre le dessus, rendant ainsi un v\u00e9hicule \u00e9lectrique parfaitement audible.<\/p>\n

En conclusion : l'\u00e9tude Vias a montr\u00e9 qu'un v\u00e9hicule \u00e9lectrique se d\u00e9pla\u00e7ant lentement peut \u00eatre plus difficile \u00e0 entendre, en particulier pour les personnes qui s'appuient fortement sur les informations auditives, ce qui constitue un argument de poids en faveur de l'am\u00e9lioration et, peut-\u00eatre, de l'harmonisation des signaux sonores des syst\u00e8mes d'alerte audio-visuels (AVAS).<\/p>","protected":false},"excerpt":{"rendered":"
