To improve safety, Volvo Trucks has developed an acoustic alert system with unique sounds for its electric truck models. The Volvo designed alert will increase safety by making pedestrians, cyclists and other road users aware of approaching trucks, which would otherwise be nearly silent. At the same time, the sounds are designed to be pleasant and unobtrusive, both for the driver and others close by. Starting on 1st July 2021, all new electric vehicles in the EU will be required to emit a certain sound level when travelling at speeds below 20 kph. The sound level required depends on the speed and gets higher as it increases. At the maximum speed of 20 kph it should be at least 56 decibels. The US has similar legislation for vehicles when driving 30 kph or slower. If the vehicle is too quiet, an external acoustic vehicle alerting system must be added.
To meet the new requirements, and at the same time maintain the benefits of lower noise levels that come with electric vehicles, Volvo Trucks has developed a unique set of premium sounds for its electric truck models. The range of sounds is the result of thorough research and testing by the Volvo Group’s own acoustics experts. It is important to note that the trucks will still be much quieter than conventional trucks.
The Volvo developed acoustic alert system for electric vehicles is actually not just one but four different sounds, informing people close by about what the truck is doing: moving forward, idling, reversing, etc. The sounds will vary in intensity, based on truck speed and will shift in frequency during acceleration and deceleration.
Ramping up electric transports
With the recently announced start of sales of three new heavy duty electric truck models – the Volvo FH, FM and FMX – Volvo Trucks now has an impressive line-up of six medium and heavy duty electric trucks. This is currently the most complete commercial electric truck range in the industry.
