OEMs Delay Vehicle Alert Sounds For Pedestrians On EVs, Hybrids
As quiet as electric vehicles and hybrids are, plans to make them noisy for the benefit of pedestrians et al have been delayed until 2018.
Edmunds reports accidents involving pedestrians climbed 6 percent in 2012 over the previous year, totaling 76,000 injuries and 4,743 deaths. Though EVs and hybrids only account for less than 2 percent of all vehicles traversing the United States, were they equipped with engine sound technology — and were the percentage to increase to a projected 4 percent in 2016 — the National Highway Traffic Safety Administration says 2,790 fewer accidents with pedestrians would result.
To help introduce the technology in all EVs and hybrids, Congress enacted the Pedestrian Safety Enhancement Act in January 2011, which mandates the U.S. Department of Transportation to develop standards for automakers to use in implementing “recognizable” sounds meant to alert pedestrians that a vehicle is approaching when the vehicle is moving down the road at 18 mph or less. The full power of the act would have come into play three years after the final rule is passed down, but delays in getting to that point — the result of comments by automakers and industry groups — have pushed the mandate to September 2018.
Meanwhile, a handful of automakers have moved ahead with implementing their versions of the safety system. Nissan has the Vehicle Sound for Pedestrians on its Leaf, while Chevrolet has a driver-operated noise onboard the Volt. However, the sounds don’t always resemble that of the ICE; Fisker’s Karma, for example, pulls its alert from Tron light-cycles and Motorola Droids, while the Kia Soul EV is waving its light saber in front of a field of crickets. Most manufacturers, though, are sitting out the PSEA until they know what the final rule will say on the matter.

- SCE to AUX I've never been teased by a bumper like that one before.
- 3SpeedAutomatic R&T could have killed the story before it was released.Now, by pulling it after the fact, they look like idiots!! What's new??
- Master Baiter "That said, the Inflation Reduction Act apparently does run afoul of WTO rules..."Pfft. The Biden administration doesn't care about rules. The Supreme Court said they couldn't forgive student load debt; they did it anyway. Decorum and tradition says you don't prosecute former presidents; they are doing it anyway. They made the CDC suspend evictions though they had no constitutional authority to do so.

When will we put audibles on pedestrians and bicycle riders? When that happens, then you can do it to my Prius.
Normal Dino Juice engines are virtually inaudible, unless 3/4 to full throttle. But half throttle to coasting? Not so much. I'm constantly pulling on to blind curves from dirt roads and easements, so I'll wait til I can no longer hear traffic approaching. Windows down, everything off, dead quiet and I'll go for it. Same with 2-way-stop intersections in near zero visibility, dense fog. But I'm not so much listening for engine sounds. But I can hear a Corolla's tires from up to a mile away. Sit a block away from a freeway and tires humming are the constant (freeway "breathing"), with an occasional WOT, modded exhaust, Harleys, compression brakes, etc.
