Product Description

Brigade QVS bbs-tek Quiet Vehicle Sounder (AVAS) 12/24v QVS-001-75 – 5385

The NEW Brigade QVS quiet vehicle sounder warns pedestrians and other VRU’s that a quiet vehicle is approaching. Incorporating bbs-tek technology – multi-frequency, directional and instantly locatable sound whicih is only heard in the hazard zone.

A front speaker system where pitch and volume increase with vehicle speed in a similar way as an internal combustion engine (sound cuts out above a pre-set speed threshold). Designed for electric and hybrid-electric vehicles of all types.

  • 12-24 v
  • IP68 speaker
  • IP30 ECU
  • Speaker Size (W x H x D) 120 x 135 x 120 mm
  • ECU Size (W x H x D) 93 x 26 x 185 mm
  • 2 Year Warranty
  • Requires TACHO or a CAN interface*


The QVS requires a 4 pulse per metre speed signal.

Tachograph – Speed signal provided by vehicle tachograph pin B8. Cut off speed of system may vary depending on tachograph type.

*CAN interface (requires additional CAN interface) – Connect the required QVS inputs to your CAN interface. Connect the CAN interface to a suitable CAN bus on the vehicle. The CAN interface will then convert the vehicle CAN signals to output signals that are compatible with the QVS input signals. The CAN interface is NOT included.

The problem with silence

Without an acoustic vehicle alerting system, 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.

The solution

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.

Heard Only Where it Matters – 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.
