Till today, we have heard of Active Sound Design inside the car’s cabin (apart from ANC= active noise cancellation) …. but never thought of Active Vibrations Design…. It is not control or cancellation --- but additional vibrations generated on the body panels for a pleasure of the passengers !!
Not content with pumping in artificial engine noises of roaring exhaust of Ferrari cars into an EV cabin, Hyundai wants its future cars to vibrate even on smooth roads like an ICE powered car [Reference: https://jalopnik.com/hyundai-sets-evs-to-vibrate-so-they-feel-more-like-gas-1848660797]
Hyundai Engineers hope that this new vibration setting could cut out any “soft” feelings of an EV! Continuous driving of the EV with very small motor-train vibrations, may make the drivers journey "boring"!
But majority of Team-BHP members ( a community of car-enthusiasts) did not like this idea. All of us seem to be under the influence of our past / present experience of the vibrations perceived on the floor or steering wheel due to combustion forces of ICE engine.
But do we not welcome the vibrations given to our Body by Electric Massager installed in various Malls ?
3 parameters for the artificial vibrators for an EV, viz., amplitude, frequency & duration, need be well selected as per ISO 2631: human perception of vibrations. Then they will bring pleasure for EV users over a long drive and their journey will be felt sportive or something interesting !
It appears, as our future vehicles become quieter and vibration-free thanks to electrification and if the road-surfaces, too, become smoother, then the Active Vibrations Design could be offered as a regular feature to these EVs to make their driving experience something special !
