To address concerns of low noise emission increasing risk for vulnerable road users, especially visually-impaired pedestrians, the approaching Vehicle Sound for Pedestrians (VSP) system has been developed by Nissan.
Discussion of the development of Nissan’s Approaching Vehicle Sound for Pedestrians (VSP) system.
Designed for implementation in Nissan’s first mass produced Electric Vehicle, the VSP emits one type of sound during forward motion, another type during ‘take-off’, when the vehicle first begins to move and a third type of sound for reverse motion.
The characteristics of the sound profile utilise knowledge of human ear sensitivity, age-related hearing loss, typical background noise conditions and visually-impaired pedestrian feedback and preferences gathered by surveys in Japan and USA.
