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.

    To complement its existing WIM offering, IRD has introduced a system to detect under-inflated and flat tyres at highway speeds. Tyre inflation pressure has both safety and economic impacts for road users and none more so than with commercial vehicles. An underinflated tyre has decreased directional control, increased risk of catastrophic failure, and negatively impacts tyre life and fuel economy. In June 2014 the USDOT published Large Truck and Bus Crash Facts 2012 in which the Federal Motor Carrier Safety

    Traffic management has largely been shielded from the sort of malicious hacking that is commonplace in other industries – but with billions of connected devices in the world it won’t stay that way, warn internet experts Keith Golden and Brandon Johnson. Traditionally isolated from networks and the internet over most of its history, the traffic management industry has largely been shielded from malicious hacking and system intrusion that have become commonplace in other industries. However, as the rate of

    Local authorities and communities must understand the impacts of the new mobility options and regulate to get the transport systems they want, according to a new report. Colin Sowman takes a look. Outside of the big cities plagued with congestion, the existing transportation system(s) often cope adequately, and the ongoing workload (maintenance, safety…) is more than enough to keep local transport authorities busy. Is it, therefore, a good use of public service employees’ time to keep abreast of the raft

    Simplifying the delivery of data and information gathered by traffic management, ticketing and other systems can improve travel efficiency and the traveller’s experience. Having quantified and analysed the previously unmonitored movement of road vehicles, trains, metros, cyclists and pedestrians, the ITS sector is a prime example of the digital world. Patterns discerned from those previously random happenings enable authorities to design more efficient transport systems, allow transport operators to run
