AVAS / eCALL

AVAS for electric cars

The silence of electric vehicles is highly appreciated by most drivers and people outside the vehicle. But in some situations a driving noise  is required in order to increase safety for pedestrian in front of the vehicle. At low speeds below 30 kmh, the cars will be required in USA  to emit some kind of sound to make their presence better known to others in the surrounding area. The European Parliament approved legislation too that requires the mandatory use of "Acoustic Vehicle Alerting Systems" for all new electric and hybrid electric vehicles. Currently Contitec is devloping  for electric vehicles  (EV-Cars) a specific speaker generating driving noise to draw attention of the pedestrian.  We have many years of experience in automotive acoustic solutions.
