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.
