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.

    Consumers who purchase an electric vehicle will find that costs to own the vehicle are competitive with conventional and hybrid vehicles, according to an analysis conducted by the US Electric Power Research Institute (EPRI). The study compares the Chevrolet Volt and Nissan Leaf with petrol-fueled cars that reflect average costs for different makes and models. Nissan lowered the price of the Leaf by about US$6,000 in January. It looks at several factors, including petrol and power prices, incentives, financi

    According to a study by the Norwegian University of Science and Technology, electric cars might pollute much more than petrol or diesel-powered cars. Researchers found greenhouse gas emissions rose dramatically if coal was used to produce the electricity. Electric car factories also emitted more toxic waste than conventional car factories, claims their report in the Journal of Industrial Energy. However, in some cases electric cars still made sense, the researchers said.

    The effect of moving objects on the electromagnetic landscape set up by cellular telephony networks can be detected and interpreted to give real-time traffic data across large geographical areas at low cost. Here, we revisit the Celldar concept. Global economic downturn has pushed public-sector agencies, transport administrations among them, to push even harder for cost efficiencies. Unfortunately, when it comes to transport safety and efficiency the public sector often has to work up to a cost rather than

    Volvo Cars is developing kangaroo detection technology to solve one of the most costly causes of traffic collisions in Australia. A team of Volvo Cars safety experts is in the Australian Capital Territory to film and study the roadside behaviour of kangaroos in their natural habitat. The data Volvo Cars collects will be used to develop the first ever kangaroo detection and collision avoidance system. According to the National Roads & Motorists’ Association (NRMA) there are over 20,000 kangaroo strikes on A
