The NHTSA will require that hybrids and EVs generate a “minimum sound”.
ECCO’s Electric Vehicle Alert System (EVAS) technology will help manufacturers comply with the regulation.
Electric vehicles and hybrids can operate in extreme silence which can be dangerous for pedestrians. In order to avoid or limit accidents and injuries, these vehicles will soon be required to emit “running noises” and ECCO has a solution.
ECCO designs and builds commercial vehicle lighting and safety solutions and their latest piece of technology is the Electric Vehicle Alert System or EVAS. It uses a reliable and robust speaker to projects a 360-degree sound perimeter around a vehicle. This speaker has been tested to resist corrosion, vibrations, dust and for us above the snow belt, salt as well.
A unique tone can be programmed through a variety of approved sounds but what is important is that the “noise”, or audible signature, must be louder than ambient street sounds. This is made possible thanks to its wide frequency band (350Hz to 5KHz).
The National Highway Traffic Safety Administration (NHTSA) details the framework of the FMVSS 141 regulation and ECCO says it’s EVAS speaker and technology are up to the task.
