“We have developed a system alert sound for the I-Pace to ensure the safety of all road users. Our potentially cost-effective technology is not disabled, and we are delighted to support the programme “assistance Dogs” as the leading charity organization for people with vision loss,” – said the technical specialist Jaguar NVH Ian Suffield.
The system is always on and is activated at speeds of up to 12 miles per hour, in the form of sound generated by the speaker, hidden behind the front grille of the car. The volume of the signal increases as you increase the speed, and additional tone indicates a change of direction when the vehicle changes direction.
System AVAS not required at higher speeds as wind noise and road noise are considered to be sufficient warnings about the approaching car.
According to representatives of Jaguar, the sound cannot be heard by the occupants inside the I-Pace. It took four years to design and build such a system.
