The 2011 Nissan Leaf was the first electric car equipped with Nissan's Vehicle Sound for Pedestrians called 'Canto'.. Electric vehicle warning sounds are sounds designed to alert pedestrians to the presence of electric drive vehicles such as hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and battery electric vehicles (BEVs) travelling at low speeds.
A white-noise back-up beeper provides a less disruptive alert than the original pure-tone alert. A back-up beeper, also known as back-up alarm or vehicle motion alarm, is a device intended to warn passers-by of a vehicle moving in reverse. Some models produce pure tone beeps at about 1000 Hz and 97-112 decibels. [1]
The first crash related fire was reported in China in May 2012, after a high-speed car crashed into a BYD e6 taxi in Shenzhen. [4] Two incidents occurred with the Tesla Model S in October 2013, one when a Model S caught fire after the electric car hit metal debris on a highway in Kent, Washington , [ 5 ] and another involving a loss of control ...
The noise levels at the sidewalk ranged from 60 to 77 decibels, higher than the 60 decibel noise level limit in the Town's Noise Ordinance during nighttime hours. [53] In 2005, the London borough of Bromley removed transverse rumble strips after residents complained of the excessive "machine gun fire" noise. [ 54 ]
Hyundai and Kia are recalling over 208,000 electric vehicles to fix a pesky problem that can cause loss of drive power, increasing the risk of a crash. The recalls cover more than 145,000 Hyundai ...
The electric motors are powered by a 4.5 kWh, 800 volt, 75 kg liquid cooled battery pack developed by Rimac Automobili, making it the first 800-volt production car. [27] [28] Koenigsegg claims that the battery pack is the most power-dense battery pack ever created for a production car. [12] [13] [22] [29]
Contrary to popular belief, differential signalling does not affect noise cancellation. Balanced lines with differential receivers will reject noise regardless of whether the signal is differential or single-ended, [1] [2] but since balanced line noise rejection requires a differential receiver anyway, differential signalling is often used on balanced lines.
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
