SOUND OF JAGUAR I-PACE PROTECTS ROAD USERS

With no engine sound, the electric Jaguar I-PACE required a new way to warn blind, visually impaired and other vulnerable road users it is approaching at low speed.

Jaguar has designed a unique Audible Vehicle Alert System (AVAS) for its first EV that meets and exceeds all forthcoming global legislation. Jaguar’s engineers have developed a sound that can be heard at speeds up to 20km/h and exceeds the 56dB(A) minimum required by forthcoming European legislation – the strictest in the world – for all new EVs from July 2019.

The I-PACE’s sound was tested by members of Guide Dogs for the Blind, the UK’s leading charity for people affected by sight loss, as part of the testing undertaken by Jaguar. It also marks the start of an on-going relationship between the two organisations.

Iain Suffield, Jaguar NVH Technical Specialist, said: “The absence of traditional engine noise from electric vehicles creates a problem for vulnerable pedestrians, such as the blind or visually impaired. This is especially true at low speeds in town centres and car parks. We developed the Audible Vehicle Alert System for the I-PACE to ensure the safety of all road users. Our potentially life-saving technology cannot be switched off and as the leading charity for people with sight loss, we are pleased to have the support of Guide Dogs to ensure real people are at the heart of our product testing.”

 

Jaguar’s engineers worked for four years to develop a soundtrack that is audible yet discreet and cannot be heard from inside the vehicle. Initial attempts to create a noise inspired by the sound of sci-fi spacecraft had to be shelved after pedestrians reacted by looking up to the sky, rather than at the road, as the vehicle approached.
