Hella Develops Acoustic Vehicle Alerting System for EVs

The acoustic warning system increases the road safety of electric, hybrid and fuel cell vehicles

Hella has developed a new Acoustic Vehicle Alerting System (AVAS) for electric vehicles. The system has been created to offer an acoustic warning system to enhance road safety of electric, hybrid and fuel cell vehicles by creating a sound that is similar to a conventional internal combustion engine.

The company will be presenting the new AVAS technology at the Bus world trade fair in Brussels from October 18 – 23. As electric, hybrid and fuel cell powered vehicles are usually silent the new technology will ensure pedestrians, cyclists and visually impaired people will be alerted of an approaching vehicle.

The system simulates a noise which rises in intensity as speed increases. The AVAS automatically creates an engine sound that reduces or is silenced as the sound of rolling tyres increases in intensity and is loud enough.
