Brigade launches QVS sound system for hybrid and EVs

Electronic vehicles (EVs) are a technical marvel – but vulnerable road users (VRUs) can’t hear them, which creates obvious safety problems.


4065 Brigade Electronics says help is at hand with its Quiet Vehicle Sounder (QVS), a speaker system which the company says reduces collisions between pedestrians and hybrid and EVs.  

The QVS, also known as an acoustic vehicle alerting system, simulates the sound characteristics of an internal combustion engine by emitting a blend of bbs-tek white sound frequencies that are used in vehicle reversing alarms.

According to Brigade, the solution changes pitch according to the speed of the vehicle and produces a sound that a VRU can identify as a vehicle.

The QVS can be retrofitted to most commercial vehicles and works from a 12 or 24 volt power source to avoid draining the power of a hybrid vehicle or EV, the company adds.

    Flir has upgraded its thermal traffic sensor and detector with traffic data collection features. The company says ThermiCam2 uses thermal energy emitted from road users – rather than light - to detect vehicles and vulnerable road users at night, over long distances and in harsh weather conditions. According to Flir, the solution can be used to detect vehicles and bicycles approaching an intersection, detect wrong-way drivers, count and distinguish vehicles from bicycles and collect traffic data using the
