AVAS - Acoustic Vehicle Alerting System

Electric and hybrid vehicles are quiet and barely audible, especially at speeds up to 20 km/h. The lack of engine and rolling noise thus eliminates a safety-relevant noise source that automatically warns other road users of an approaching vehicle. Since the advent of electric vehicles, pedestrians have increasingly fallen victim to this source of danger. This circumstance has forced the industry’s hand; the result is AVAS.

Our Acoustic Vehicle Alerting System is a sound module controlled via the CAN-BUS of each electric vehicle. Thus, it can emit a driving sound during start-up (0-20km/h), which warns other road users of an approaching vehicle; it is thus safety-relevant and a marketing tool. We have recognized the extended advantage of AVAS and use the sound reproduction for their own individual electric vehicle sound, thus creating a recognition value, which is significantly incorporated into the vehicle design.
