The Infiniti M35h hybrid will become the world’s first hybrid to feature an audible pedestrian warning system as standard when it goes on sale in six months time. The new Approaching Vehicle Sound for Pedestrians (VSP) system is computer controlled and links an in-car sound synthesiser with a speaker built in to the front bumper. A range of high-low sounds at different volume levels has proved to be the most effective and least intrusive noise.
The noise from the VSP system on the Infiniti M35h sweeps from high to low frequency depending on vehicle speed and whether the M35h is accelerating or decelerating. It is loudest at start-up to give a clear indication the vehicle is beginning to move off, while an intermittent tone is used when reversing, both sounds have been calculated to ensure the Infiniti M35h cannot surprise pedestrians and the visually impaired as it approaches.
Unlike other manufacturers and in keeping with Infiniti’s generous standard features policy across all its models, Approaching Vehicle Sound for Pedestrians will come ready installed on every Infiniti M35h in Europe when sales commence from spring 2011 (depending on country). Approaching Vehicle Sound for Pedestrians joins a host of innovative safety systems available on the Infiniti M35h including the Dynamic Safety Shield, standard on Premium versions.
