Brigade Quiet Vehicle Sounder (AVAS)

Compact, windscreen-mounted dual camera system that uses AI technology to provide event warnings, high-definition incident recording and monitor driver behaviour.

Main Features

  • Warns pedestrians and other VRU’s that a quiet vehicle is approaching
  • Multi-frequency sound
  • Directional and locatable – The sound is only heard in the hazard zone
  • Front speaker system
  • Pitch and volume increase with vehicle speed to mimic an internal combustion engine
  • Operational below speeds of 20MPH
  • Front sounder operational when ignition activated (silenced when parking brake applied)
  • CE marked, E-Marked: UNECE R10 compliant, FCC approved, IC Marked, UNECE R138 compliant, 49 CFR Part 571 and 585 Federal Motor Vehicle Safety Standards compliant

Description

The Quiet Vehicle Sounder (known as an Acoustic Vehicle Alerting System (AVAS)warns vulnerable road users of an approaching electric/hybrid vehicle. Since 2010, Brigade has been involved in the QRTV (Quiet Road Transport Vehicles) working group to establish requirements for a UN standard.
 
 
Brigade has developed a multi-frequency Quiet Vehicle Sounder, integrating the patented bbs-tek® technology. bbs-tek® uses a wide range of White Sound® frequencies. This enables anyone in the direct path of the vehicle to instantly locate where and what direction the sound is coming from and take evasive action if required. There is no safer alternative.
 
 
Without an Acoustic Vehicle Alerting System (AVAS), electric and hybrid vehicles are almost silent; they are only audible once they have built up some speed (approximately 20kph) when wind and road noise generate enough sound that they can be heard. Studies have concluded that electric and hybrid vehicles pose a danger to vulnerable road users (VRU) and increase the risk of incidents with pedestrians by up to 80%. Sound is an important contributor to road safety for pedestrians, not only for the blind or visually impaired.
 
 
Brigade’s Quiet Vehicle Sounder creates a “sssshhhhh” sound which is gentle on the ear and dissipates quickly once the vehicle has passed, meaning it can only be heard in the danger zone (0-20mph). People living and working in the surrounding areas will not be impacted by unnecessary sound, reducing the impact on peoples health.
 
 
Both the US and the EU are introducing standards to ensure minimum sound requirements for electric and hybrid vehicles to protect VRUs. An Acoustic Vehicle Alerting System (AVAS) will need to be fitted to make electric or hybrid vehicles “sound similar” to vehicles with combustion engines when travelling at low speed. From July 2019, all new hybrid and electric vehicles to be sold in Europe will need an acoustic vehicle alerting system to emit sound when travelling at low speeds.
