捷豹电动车增加行人警告噪音 From July 2019, by the EU law every new electric car sold will have to make a noise so that pedestrians* can hear them coming. But despite having nine months until that deadline, Jaguar has revealed the sound its electrified vehicles will make in the future, including the I-Pace SUV, and it is likely to divide opinion. With no engine sound at all, road safety groups have previously referred to electric cars as silent killers. Called the Audible Vehicle Alert System, it has been developed for Jaguar’s first electric car, the I-Pace. With the help of Guide Dogs for the Blind, Jaguar engineers have developed a sound that can be heard at speeds up to 20km/h and exceeds the 56 decibel minimum required by the forthcoming European legislation, which will be the most strict in the world. It is reported that it sounds like a low-level air-raid siren. The alert increases in pitch and volume in line with the speed of the vehicle and, when in reverse, is accompanied by an additional tone that indicates the change in direction.(SD-Agencies) |
